for this update to the City of Pismo Beach's established Sewer System Management Plan (SSMP). A list of abbreviations used in this SSMP update has been provided at the end of this chapter to assist the reader to understand the information presented. 1.1 PURPOSE This SSMP update has been prepared by Cannon Corp. for the City of Pismo Beach (City) in order to comply with the State Water Resources Control Board (SWRCB) Order No. 2006-0003 (Order No. 2006-0003), adopted May 2, 2006, and amended MRP Order No. WQ 2008-0002-EXEC, and WQ 2013-0058-EXEC, adopted February 20, 2008 and September 9, 2013, respectively. A copy of Order No. 2006-0003 is included in Appendix A, and a copy of WQ 2008-0002-EXEC and WQ 2013-0058- EXEC is included in Appendix B. The purpose of this SSMP update is to provide a plan and schedule to properly manage, operate, and maintain all parts of the sanitary sewer system.This will help reduce and prevent sanitary sewer overflows (SSOs), as well as mitigate any SSOs that do occur. 1.2 STUDY AREA The City is located mid-way between Los Angeles and San Francisco in the southern portion of San Luis Obispo County(Figure 1.1). It is located along Highway 101, approximately eight miles south of the City of San Luis Obispo.The City is a popular resort community situated directly on the Pacific Ocean and extends to the east into the foothills of the coastal mountain range. 1.3 BACKGROUND Nationally, SSOs have been in the regulatory spotlight since 1995.The number and frequency of SSOs was identified as a public health and water quality issue in the Environmental Protection Agency Report to Congress (August 2004). On May 2, 2006,the California SWRCB adopted Statewide General Waste Discharge Requirements for Sanitary Sewer Collection Systems (SSS WDRs),focusing on the reduction of SSOs. The WDRs required all collection systems with more than one mile of sewer pipe to apply for coverage under the WDRs by November 2, 2006. The Monitoring and Reporting Program (MRP) was amended twice, once in 2008 and again in 2013, to re-establish monitoring, record keeping, reporting, public notification requirements, and SSO categories for Order 2006-0003-DWQ. June 2020 1-1 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\01.doc • y 1 �I 5 u h js I'v u S • e''�• '• s;- E Q1_ It e a t M ME , Or 140 I - PISMO BEACHPISMO BEACH, I � CALIFORNI - - OBISPO COUNT • . • . • A • NI'L11'1,N111110 • • Several Regional Water Quality Control Boards (RWQCBs) have existing requirements for collection systems and SSOs.The statewide WDRs supplement the existing RWQCB requirements, with the intent to gradually make requirements consistent statewide. However, RWQCBs have the authority to adopt more stringent regional requirements. The requirements for the SSMPs are closely related to the Environmental Protection Agency's Capacity, Management, Operation, and Maintenance (CMOM) rule (published in the Federal Register in January 2001) and they constitute a best management practices approach to the regulation of collection systems.The SSMP elements are: • Goals • Organization • Legal Authority • Operation and Maintenance Program • Design and Performance Provisions • Overflow Emergency Response Plan • Fats, Oils, and Grease (FOG) Control Program • System Evaluation and Capacity Assurance Plan • Monitoring, Measurement, and Program Modifications • SSMP Program Audits • Communication Program The SWRCB adopted a resolution in November 2004, supporting the SSMP approach to regulating collection systems.The SWRCB acted at its meeting on May 2, 2006 to require all public wastewater collection system agencies to be regulated under General Waste Discharge Requirements.The SWRCB action mandates the development of an SSMP and the reporting of SSOs using an electronic reporting system.The SWRCB requires periodic performance audits for the SSMP as well as updating and recording changes to the SSMP. 1.4 SCHEDULE - NOT USED 1.5 REPORT ORGANIZATION This SSMP update contains twelve chapters.

This will help reduce and prevent SSOs, as well as mitigate any SSOs that do occur." 2.2 SSMP GOALS This SSMP has been prepared in order to achieve the following goals: • To properly manage, operate, and maintain all aspects and components of the City's wastewater collection system. • To provide the wastewater collection system with adequate capacity to convey peak wastewater flows. • To minimize the occurrence of SSOs to the extent possible. • To mitigate the impacts that are associated with any SSO that may occur. • To meet all regulatory requirements related to the SSMP and SSO reporting system. 2.3 DEFINITIONS An SSO is defined as any overflow, release, discharge or diversion of untreated or partially treated wastewater from a sanitary sewer system.There are four categories of SSOs as established by the SWRCB's Order: • Category 1:This category includes discharges of any volume of sewage resulting from a failure in the City's sanitary sewer system that: a. Result in a discharge to a drainage channel and/or surface water; or b. Discharge to a Municipal Separate Storm Sewer System (MS4)that was not fully captured and returned to the sanitary sewer system. • Category 2:This category includes all discharges of sewage resulting from a failure in the City's sanitary sewer system that: June 2020 2-1 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\02.doc a. Equal or exceed 1,000 gallons b. Does not reach surface water, a drainage channel, or a MS4 • Category 3: This category includes all other discharges of sewage resulting from a failure in the City's sanitary sewer system. • Private Lateral Sewage Discharges: Sewage discharges that are caused by blockages or other problems within a privately owned lateral. As part of Order No. 2006-0003, all agencies that own or operate sanitary systems greater than one mile in length that collect and/or convey untreated or partially treated wastewater to a publicly owned treatment facility are required to report Category 1, 2 &3 SSOs.The reporting of Private Lateral Sewage Discharges is optional. 2.4 PROHIBITION The statewide Waste Discharge Requirements (WDRs) prohibit any SSO that results in a discharge of untreated or partially treated wastewater to waters of the United States or that causes a "nuisance," as defined in California Water Code Section 13050(m).There is no "affirmative defense" for unforeseen or unavoidable SSOs. Instead,the WDRs include the concept of "enforcement discretion," and identify seven specific factors that must be considered in an enforcement action, such as the extent to which the discharger has complied with the provisions of the WDRs. In the event of an SSO, all feasible steps are taken to limit the released volume and prevent untreated water from entering storm drains, creeks, etc.All SSOs are reported through a new statewide online reporting system (the California Integrated Water Quality System). The procedures for controlling, cleaning, and reporting SSO's are described in the Chapters 3 &7 of this SSM P. June 2020 2-2 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\02.doc Chapter 3 ORGANIZATION This chapter identifies the responsible representative from the City of Pismo Beach (City)for the implementation of this Sewer System Management Plan (SSMP). It also includes an organizational chart and a chain of communication for reporting sanitary sewer overflows (SSOs). 3.1 REGULATORY REQUIREMENT Order No. 2006-0003 specifies that the SSMP must identify the following: a. The name of the responsible or authorized representative for the implementation of the SSMP. b. The names and telephone numbers for management, administrative, and maintenance positions responsible for implementing specific measures of the SSMP program.The SSMP must identify lines of authority through an organizational chart or similar document with a narrative explanation; and C. The chain of communication for reporting SSOs,from receipt of a complaint and other information, including the person responsible for reporting SSOs to the State and Regional Water Board and other agencies if applicable (such as County Health Officer, County Environmental Health Agency, Regional Water Quality Control Board, and/or State Office of Emergency Services (OES). 3.2 AUTHORIZED REPRESENTATIVE The City's authorized representative for the implementation of the provisions set forth in this SSMP is Mr. Russell Fleming, Utilities Manager. Mr. Fleming is authorized to submit electronic spill reports to the State Water Regional Control Board (SWRCB), as well as reporting SSOs to other applicable agencies (such as County Health Officer, County Environmental Health Agency, Regional Water Board, and/or State Office of Emergency Services (OES)). The City's authorized representative is permitted to establish a data entry designee for the online reporting requirement of Order No. 2006-0003. Mr. Fleming may therefore establish a data entry designee, should he choose to do so. 3.3 ORGANIZATIONAL HIERARCHY The organizational hierarchy for the implementation of the measures specified in this SSMP is shown in Figure 3.1.Table 3.1 contains the contact information for the positions specified in Figure 3.1.A description of those positions is provided in this section.

Successful performance of the work requires skill in coordinating the work of the assigned function with other departments.This class is distinguished from the Wastewater System Supervisor in that the latter is full supervisory-level class in the wastewater systems operations series responsible for organizing, assigning, supervising, and reviewing the work of assigned staff involved in wastewater collection and treatment systems, facilities, and operations. 3.4 CHAIN OF COMMUNICATION FOR REPORTING SSO'S The City's Overflow Emergency Response Plan (OERP) contains the procedures utilized by the City to notify the primary SSO response crews. In general, calls from the public during business hours (7:30 AM to 4:00 PM) regarding possible SSOs are forwarded to the Utilities Manager, who is responsible for the coordination of an appropriate response, depending on the type and severity of the problem. During non-business hours,weekends, and holidays,the designated "wastewater standby operator" is contacted by phone. If no response from the standby operator is received within 30 minutes,the Utilities Manager is contacted by phone or Pismo dispatch. The SSO reporting procedure is dependant upon the type and volume of spill that has occurred.The SWRCB has developed an online SSO reporting system, called the California Integrated Water Quality System (CIWQS), which is available at http://ciwgs.waterboards.ca.gov/ciwqs/index.jsp.The City is required to use this reporting system to submit SSO spill reports, should they occur, or no spill certification reports. June 2020 3-5 FAproj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\03.doc Appendix B contains screen captures from the CIWQS.All reports on CIWQS are completed and submitted electronically.The system is password protected and has been created in such a way as to facilitate the ease of use. Figure 3.2 is a flow chart that outlines the reporting procedure that the City will follow should an SSO occur. A description of the Category 1 & 2 and Category 3 SSO reporting procedure is also provided in Sections 3.4.1 and 3.4.2, respectively. It is not anticipated that the City will report SSOs caused by blockages or problems within a privately owned lateral, although the City may choose to do so. 3.4.1 Category 1 & 2 SSO Reporting Procedure The current Order No. 2006-0003-specifies certain requirements for the reporting of SSOs.The City intends to comply with these requirements. Upon notification that an SSO has occurred, an initial report is prepared by the Utilities Manager's established data entry designee, should he choose to establish one, and submitted through the SWRCB's online reporting system,which is called the California Integrated Water Quality System (CIWQS).This initial report is submitted as soon as is practicable, but no later than three business days after the City has been made aware of the SSO. The initial report is then expanded and updated if new information on the overflow is made available. Upon review of the updated report by the Utilities Manager, it is finalized and certified on CIWQS.This final certification is completed as soon as possible, but no later than 15 calendar days of the conclusion of SSO response and remediation. In the event a Category 1 SSO equals or exceeds 1,000 gallons, Cal OES shall be notified and obtain a control number as soon as possible, but no later than 2 hours after (A)the City has knowledge of the discharge, (B) notification is possible, and (C) notification can be provided without substantially impeding cleanup or other emergency measures. If an SSO discharges 50,000 gallons or greater to surface waters, an SSO technical report will be submitted in the CIWQS Database as soon as possible, but no later than 45 calendar days after the SSO end date. In addition, the City will collect water quality samples within 48 hours of the SSO.The SSO technical report will include the water quality results and sampling locations. 3.4.2 Category 3 SSO Reporting Procedure The requirements for the reporting of Category 3 spills by the SWRCB are far less stringent than the Category 1 requirements. Upon notification that a Category 3 spill has occurred, all information relating to that spill is gathered. Once all the data on the spill is available, a report is completed by the Utilities Manager established data entry designee,should he choose to establish one.The report is then reviewed by the Utilities Manager and submitted on CIWQS.This report is submitted as soon as possible, but no later than 30 days after the end of the calendar month in which the SSO occurs.

By following this program, the City will reduce blockages and SSOs to the greatest extent practicable. This program is summarized in the following sections. Selected forms used by City Staff in the performance of routine maintenance are included in Appendix D. 5.3.1 Sanitary Sewer Main Line Cleaning In order to reduce the frequency and extent of stoppages caused by clogged sewers,the City has developed a procedure for sanitary sewer main line cleaning.All sanitary sewer main lines are cleaned once every two years. Routine cleanings are tracked in the office on a collection system map. Sewer lines are crossed off after the field crew finish cleaning.The map is replaced after every cleaning cycle. Other designated "hot spots' have been identified by the City for more frequent cleaning and maintenance, due to various maintenance issues.These "hot spots" are cleaned more frequently, as identified in Table 5.1 and shown in Figure 5.2. "Hot spots" are identified during regular cleaning procedures from video inspections of the lines. 5.3.2 Pump Station Maintenance Program The City has ten pump stations throughout the City,which are monitored through the City's Supervisory Control and Data Acquisition (SCADA) system.This system will notify the City of a power failure or high water levels. Each pump is physically inspected weekly.This includes checking for unusual operating noises and vibrations, oil leaks, water leaks, and other problems that may be apparent. All maintenance log sheets from the field are electronically filed. 5.4 PISMO BEACH'S REHABILITATION AND REPLACEMENT PLAN The City has developed a system for the identification and prioritization of needed rehabilitation projects,through the 2000 Master Plan.The result of this system is the City's capital improvement program (CIP),which identifies rehabilitation projects and the time for which they are scheduled to be undertaken. As of 2019, a vast majority of the CIP projects identified in the SSMP in 2007 have been completed or are nearing completion.The CIP has been updated to capture any remaining rehabilitation projects.The results of the CIP updates are tabulated in Table 9.12.This 2019 CIP was developed in collaboration with Cannon's Engineer and Pismo's collections staff.

USA training and basic electrical training is required for all staff. Licensing and certification requirements vary depending on position.Table 5.2 lists these requirements for the City's maintenance positions. The City has a two level operator structure,which facilitates staff training. In this system,the higher-level maintenance workers(Wastewater Plant Operator II) provide training to lower level maintenance workers (Wastewater Plant Operator 1). Lower level maintenance workers thereby gain valuable experience by working under and learning from the more experienced workers. 5.6 EQUIPMENT AND REPLACEMENT PART INVENTORIES A list of major equipment used for the sewer collection system is included in Table 5.3.This major equipment includes portable pumps, a backhoe, a portable generator, an air compressor, and other equipment and vehicles.This equipment is used by operations staff in the performance of routine and emergency maintenance to the City's sewer system. Additionally,the City has identified contract tanker trucks and generator rentals that can be utilized should the City require them.

The County standards are summarized in the following subsections. 6.2.2.1 Wastewater Generation Factors The County improvement standards specify that an average wastewater generation factor of 100 gallons per capita per day(gpcd) be used for the determination of average wastewater flow. Average flow is determined by multiplying the average wastewater generation coefficient by the by the estimated future population served by the facility.The future population is determined for a 50-year period, which is the length of time that the capacity of the sanitary sewer will be adequate. Because the City and County are very popular tourist destinations,the number of visitors that are served by each facility,which is associated with recreational uses, should be converted into equivalent full-time residents by multiplying the number of visitors by the appropriate factor, determined as follows: • Day User: 0.1 -0.2 • Seasonal Visitor: 0.5 -0.8 June 2020 6-2 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\06.doc Day-use visitors are defined as those who do not stay overnight (e.g. boaters or picnickers), and seasonal visitors are those who stay for short multi-day stays during peak recreational seasons (e.g. for camping or cabins). 6.2.2.2 Peaking Factor For the design of sewer facilities, a peaking factor of 2.0 should be applied to the average wastewater flow computed pursuant to Section 6.2.2.1 of this report to account for peak flow. 6.2.2.3 Depth to Diameter(d/D) Criteria Pipes shall be designed with the maximum flow depth to pipe diameter(d/D) ratios presented in Table 6.2, depending on the pipe diameter. Table 6.2 Design d/D Ratios Sewer System Management Plan City of Pismo Beach Pipe Diameter Maximum Allowable d/D Ratio 15-inches or Less 0.50 Greater than 15-inches 0.67 Source: San Luis Obispo County Public Improvement Standards 6.2.2.4 Minimum Velocity Sanitary sewer grades are to be designed to provide a minimum velocity of 2 feet per second (ft/s) when flowing at peak discharge as defined in Section 6.2.2.2 of this report.The purpose of such a minimum velocity is to prevent the deposition of solids (or to provide self-cleaning velocities).Table 6.3 presents the minimum pipe slopes required by the County improvement standards. 6.2.2.5 Maximum Velocity The County improvement standards specify that in order to provide erosion protection in sewer pipelines, sanitary sewers shall not exceed 10 ft/s at peak flow. Additionally,the maximum design discharge shall not exceed the flow at critical slope and velocity. Sanitary sewers should not be designed for flow conditions at critical slope and velocity. 6.2.2.6 Changes in Pipe Size or Angle Point The County improvement standards specify that whenever a change in pipe size or an angle of 20 degrees or greater in alignment occurs,the flow line of the pipe flowing into the manhole shall be a minimum of 0.17 feet above the flow line of the pipe flowing from the manhole, or an amount that is necessary to match the inside crowns of the pipe,whichever is greater.

Source: City of Pismo Beach Public Works Department Engineering Standards and San Luis Obispo County Public Improvement Standards. 6.3 INSPECTION AND TESTING STANDARDS The County improvement standards provide guidelines for the testing and inspection of sanitary sewer facilities.These standards are summarized in the following subsections. 6.3.1 Cleaning Prior to acceptance of any sewer line by the City,the sewer line shall be cleaned with a Wayne-type sewer-cleaning ball under hydrostatic pressure. Any stoppage, dirt, or foreign material shall be removed from the lines. All materials removed shall be collected and vacuumed out of the system at a manhole selected by the City, and no debris shall be washed or otherwise deposited into the system. 6.3.2 Hydrostatic Test Procedure Prior to testing, a section of sewer line shall be prepared for testing by plugging the upper side of the downstream manhole and all openings in the upstream manhole except the downstream opening. Where grades are slight,two or more sections between manholes may be tested at once. Where grades are steep, and excessive test heads would result from testing from one manhole to another,test tees the full size of the main shall be installed at intermediate points so the maximum head on any section under test will not exceed 12 feet.The following sequence shall be used: 1. The section of sewer line prepared as above shall be tested by filling with water to an elevation five feet above the top of the pipe at the upstream end of the test section, or five feet above the existing ground water elevation, whichever is greater.The water should be introduced into the test section four hours in advance of the official test period to allow the pipe and joint material to become saturated.The pipe shall then be refilled to the original water level. 2. At the beginning of the test,the elevation of the water in the upper manhole shall be carefully measured from a point on the manhole rim. After a period of four hours, or less with the approval of the City,the water elevation shall be measured from the same point on the manhole rim and the water loss during the test period calculated. If this calculation is determined to be difficult,then enough water should be added to restore the water to the original level, and the amount added taken as the total leakage. 3. Should an initial test show excess leakage in a section of line, it is permissible to draw the water off and test the manholes that contained water.This test shall be made by plugging all the openings in the manholes and filling with water to the same elevation as existed during the test.The leakage from the manhole may be deducted from the total leakage of the test section in arriving at the test leakage. After the testing is complete,the manhole shall be waterproofed by grouting. Other waterproofing methods may be used if approved by the City. June 2020 6-7 FAproj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\06.doc 4. The allowable leakage in the test section shall not exceed 500 gallons per mile, per 24 hours, per inch diameter of pipe tested at the 5-foot test head. 5. If it is necessary or desirable to increase the test head above five feet,the allowable leakage will be increased at the rate of 80 gallons for each foot increase in head. 6. Test sections showing leakage in excess of that allowed shall be repaired or reconstructed as necessary to reduce the leakage to that specified above, and the line retested, after a minimum period of 24 hours during which no additional water shall be introduced into the line. 6.3.3 Air Test Procedure Each section of sanitary sewer between two successive manholes shall be tested by plugging all pipe outlets with suitable test plugs. Air shall be slowly added until the internal pressure is raised to 4.0 pounds per square inch gauge (psig). The compressor used to add air to the pipe shall have a blowoff valve set at 5 psig to assure that at no time the internal pressure exceeds 5 psig.The internal pressure of 4 psig shall be maintained for at least two minutes to allow the air temperature to stabilize, after which the air supply shall be disconnected and the pressure allowed to decrease to 3.5 psig.The time in minutes that is required for the internal pressure to drop from 3.5 psig to 2.5 psig shall be measured and the results compared with the values tabulated in Table 6.6. The values tabulated in Table 6.6 shall be used for the respective diameter pipes except where the distance between successive manholes is less than the tabulated values, or the pipe diameter is less than eight inches, in which case the following formula will be used to determine the test time: T=0.000183 d2 L Where: T=test time (minutes) d = inside diameter of pipe (inches) L= distance between successive manholes (feet) If the pressure drop from 3.5 psig to 2.5 psig occurs in less time than the tabulated or calculated values,the pipe shall be repaired and, if necessary, replaced and relaid at the contractor's expense until the joints and pipe shall hold satisfactorily under this test.The contractor shall furnish all labor, air test equipment, and all other materials for making the required air test at his or her own expense.After the sewer lines have been properly backfilled to a depth where additional backfilling will not disturb the position of the pipe, all or any sections that the City may select may be tested. In no case shall the required minimum backfill be less than four feet above the top of the pipe before subjecting the line to the test.The contractor shall supply all equipment, material and perform all tests as required prior to final approval.

A rigid mandrel, with a circular cross-section having a diameter of at least 95 percent of the specified average inside diameter, shall be pulled through the pipe by hand.The minimum length of the circular portion of the mandrel shall be equal to the nominal diameter of the pipe. Unless otherwise permitted by the City, any over-deflected pipe shall be uncovered and, if not damaged, reinstalled. Damaged pipe lengths shall not be reinstalled but shall be removed from the work site.Any pipe subjected to any method or process other than removal, which attempts (even successfully)to reduce or cure any deflection, shall be uncovered, removed from the work site, and replaced with new pipe. 6.3.5 TV Inspection The County improvement standards specify that if a sewer facility fails either the air, hydrostatic, or deflection tests,video (or TV) inspection shall be required for the main. June 2020 6-9 FAproj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\06.doc 6.3.6 Force Mains Each section of pipe to be tested shall be slowly filled with water and all air expelled from the pipe. After the pipe has been filled, it shall be allowed to set for a period of not less than 24 hours.The pipe shall then be refilled to the original water level and subjected to a pressure of not less than 150 pounds per square inch, or the service pressure plus 50 pounds,whichever is greater, for a period of two hours.All exposed joints, bends, angles, and fittings shall be closely examined during the test. Any part of the line which proves to be defective shall be replaced and the line retested. The maximum allowable leakage shall not exceed 100 gallons per mile, per 24 hours, per inch of nominal diameter.

SSO response and reporting requirements were revised with the July 30, 2013 amendment to State Water Board's GWDRs for sanitary sewer systems. At a minimum,this plan must include the following: a. Proper notification procedures so that the primary responders and regulatory agencies are informed of all sanitary sewer overflows (SSOs) in a timely manner; b. A program to ensure an appropriate response to all overflows; C. Procedures to ensure prompt notification to appropriate regulatory agencies and other potentially affected entities (e.g. health agencies, Regional Water Boards,water suppliers, etc.) of all SSOs that potentially affect public health or reach the waters of the State in accordance with the monitoring reporting program (MRP),the California Water Code, other State Law, and other applicable Regional Water Board waste discharge requirements (WDRs) or National Pollutant Discharge Elimination Program (NPDES) permit requirements.The SSMP should identify the officials who will receive immediate notification; d. Procedures to ensure that appropriate staff and contractor personnel are aware of and follow the Emergency Response Plan and are appropriately trained; e. Procedures to address emergency operations, such as traffic and crowd control and other necessary response activities; and f. A program to ensure that all reasonable steps are taken to contain and prevent discharge of untreated or partially treated wastewater to waters of the United States and to minimize or correct any adverse impact of the environment resulting from the SSOs, including such accelerated or additional monitoring as may be necessary to determine the nature and impact of the discharge. 7.2 OVERFLOW EMERGENCY REPSONSE PLAN An Overflow Emergency Response Plan (OERP) was developed for the City in order to comply with the requirements of Order No. 2006-0003.The OERP was revised to comply with the amended SSO response and reporting requirements from Order No. WQ 2013-0058 EXEC.The updated OERP is included in Appendix G of this SSMP.

The response program is summarized as follows: • Spill Response Procedure.The following general procedure should be followed in the response to an SSO: — Inspect reported spill location — Identify cause of spill and equipment and manpower required for termination of spill — Record the following information ■ SSO location ■ Did SSO reach surface water, a drainage channel, or drainage structure? If so, name of affected body of water ■ Did SSO reach an MS4? Was the total SSO volume recovered? ■ Estimated SSO volume from all discharge points (gallons) ■ If ongoing, estimated SSO discharge rate (gallons per minute) June 2020 7-2 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\07.doc ■ Estimated SSO volume that reached surface water, a drainage channel, or drainage structure ■ Estimated SSO volume recovered ■ Number of SSO appearance points along with a description and location of each point ■ Date and time of notification, or self-discovery, of SSO ■ Time of Arrival ■ Estimated start date and time of SSO ■ Was Cal OES contacted? If so, date and time of call and assigned control number Public Health Hazard - Report Findings to Supervisor Other procedures for SSO containment, mitigation, and clean up have also been provided in the City's OERP. 7.5 NOTIFICATION OF REGULATORY AGENCIES The City's OERP provides a discussion of the procedures that should be followed by the City in the notification of the appropriate regulatory agencies of an SSO.The following agencies are required to be notified by the OERP: California Emergency Management(Cal-EMA): If the sewage spill is over 1000 gallons or reaches waterway, call (800-852-7550) or(916-845-8911). Record case number for reference and report. Regional Water Quality Control Board (RWQCB): If spill is over 1000 gallons, reaches waterway, or occurred in area with likely public contact, call (805-549-3147) as soon as possible. (Must be reported within two (2) hours of the time you have knowledge of the spill.) Give the required spill information. If you leave a message, leave your name and call back number. A follow-up call within 24 hours of the spill must be made confirming that all required agencies have been notified within the two hour timeframe.Written report must be submitted within 5 days. Spills that meet CIWQS criteria shall be appropriately reported by the City's Utilities Manager. SLO County Environmental Health: If spill is over 50 gallons, call (805-781-5544). Give the spill information and let them know that the written report will be sent via fax. (Fax: 805-781-4211) California Department of Fish and Wildlife: If spill reaches waterway, call state office (916-445- 0045) or Business Phone at (916-358-1300). Contact local warden:Jim Solis, (805-610-3919). Leave message with same information as above. Speak fast, or the machine will cut you off. June 2020 7-3 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\07.doc Proposition 65/County Board of Supervisors: If spill is a threat to the environment or human health, call the County's Public Works Department at (805-781-5450). Provide the spill information and let them know that the written Sewage Spill Report will be sent via fax(Fax: 805-781-1229). The major regulatory agency that has not been considered by the OERP is the State Water Resources Control Board (SWRCB). Notification of this agency is required by Order No. 2006-0003 and will be accomplished through the California Integrated Water Quality System (CIWQS) (the SWRCB's online SSO reporting database).The time frames and reporting requirements for the SWRCB are dependant upon the size and type of the SSO. Spills defined as a Category 1 SSO are the most serious, and hence have the most stringent reporting requirements.The specific requirements for CIWQS are provided in greater detail in Section 3.4.1 and 3.4.2 of this report. 7.6 EMERGENCY RESPONSE PLAN AWARENESS AND TRAINING Section 2 of the City's OERP and Appendix C of the OERP contains procedures so that all City Staff who are involved in the implementation of specific provisions of the SSMP or OERP, or are involved in any way with the response to SSOs,should be very familiar with the standard operating procedures for responding and mitigating SSOs. Copies of the OERP should be made available to these key City Staff members. Additionally,Section 7 of the OERP addresses training for all City personnel who may have a role in responding to, reporting, and/or mitigating an SSO. 7.7 EMERGENCY OPERATIONS Section 2 of the City's OERP contains the emergency response procedures that should be followed by SSO response crews.This includes provisions for dispatching, crew instruction, requests for additional resources, assessing property damage, field supervision and inspection, hazardous materials, and crowd control, traffic diversion, and other emergency operations. 7.8 SSO SURFACE WATER IMPACT MITIGATION PROGRAM Section 2.3.5 of the City's OERP contains procedures for City Staff to follow in the event of an SSO that discharges into waters of the United States.These procedures will vary on a case-by-case basis. June 2020 7-4 FAproj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\07.doc Chapter 8 FOG CONTROL PROGRAM This chapter discusses the need for a Fat, Oil, and Grease (FOG) control program.The purpose of such a program is to limit the amount of fats, oils, and greases that enter the collection system to conform to the requirements of the SWRCB. 8.1 REGULATORY REQUIREMENT Order No 2006-0003 specifies that each SSMP must include an evaluation of the service area of the City to determine whether a FOG control program is needed. If no FOG program is needed, justification for why it is not needed must be provided. If FOG is considered to be a problem, a FOG source control program must be prepared and implemented, including the following as appropriate: a. An implementation plan and schedule for a public education outreach program that promotes the proper disposal of FOG; b. A plan and schedule for the disposal of FOG generated within the sanitary sewer system service area.This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of FOG generated within a sanitary sewer system service area; C. The legal authority to prohibit discharges into the system and identify measures to prevent sanitary sewer overflows (SSOs) and blockages caused by FOG; d. Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, Best Management Practice (BMP) requirements, record keeping and reporting requirements; e. Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the FOG ordinance; f. An identification of sanitary sewer system sections subject to FOG blockages and establishment of a cleaning maintenance schedule for each section; and g. Development and implementation of source control measures for all sources of FOG discharged into the sanitary sewer system for each section identified in (f) above. 8.2 EXISTING FOG CONTROL MEASURES The City has developed a system of FOG control measures,which have formed the basis of this plan.The City's existing FOG control measures,which are summarized in Appendix H.1, mainly consist of requiring grease traps for Food Service Establishments (FSEs)within the City and performing annually or biannually inspections of each FSE. It is recommended that the City continue to implement these existing measures, as well as those additional measures identified in this plan. June 2020 8-1 FAproj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\08.doc 8.3 SERVICE AREA FOG EVALUATION The City's FOG Control Plan notes that a good deal of the City's SSO and maintenance "hot spots" have been determined to have originated from FOG related problems (Figure 8.1).This is primarily due to the City's heavy tourism industry,which includes a large number of FSEs. As is true with many other municipalities,the City conducts investigations of problem areas of the sewer collection system on an "as-needed" basis. In the City, major FOG problems have been identified by operator experience with areas that have posed problems in the past. Limited video inspection projects have been conducted on areas if the system where it is suspected that a problem may be present.The following problem areas identified with the above procedure are summarized in Table 8.1. Table 8.1 FOG "Hot Spots" SSMP- FOG Control Plan City of Pismo Beach Number Location Description 1 Spyglass Drive S-01 to S-10 2 Placentia Street V-69 to V-73 8.4 PUBLIC EDUCATIONAL OUTREACH The City utilizes personal contact with business owners for the proper disposal of FOG and other SSO prevention measures.The City's website posts information for FSEs regarding the recommended BMPs for FOG control, requirements for grease interceptor and inspections and educational information for FOG related issues in the sewer system.The City's online public documents are included in Appendices H.1, H.2, and H.3 of the SSMP. 8.5 FOG DISPOSAL The City's FOG Control Plan has identified methods for FOG disposal within the City.The following companies have been identified as capable of accepting and disposing of FOG: Clay's Septic and Jetting 3547 South Higuera Street, Suite E San Luis Obispo, CA 93401 Phone: (805) 543-5552 June 2020 8-2 FAproj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\08.doc t �� �` r ►r � s �r� 7 BARCELONA 2� eRgVq FOOTHILL FREEWAY LS r '• s M 14 r SPYGLASS ST ANDREWS LS VISTA DEL MAR LS CC 2 2 ,..

Enforcement of the FOG Control Program is implemented by the Regulatory Compliance Coordinator, Lauren Herrick.The City's enforcement measures are outlined in Section 9 of this chapter. 8.7 GREASE REMOVAL DEVICE REQUIREMENTS The City requires all FSEs, as well as other establishments as necessary,to install grease removal devices, in order to prevent the discharge of FOG in large quantities into the sanitary sewer system. The City uses the California Plumbing Code as its standard for the design and installation of grease traps. Excerpts of the California Plumbing Code,which are supplied to the City's FSEs, are included in Appendix H.4. 8.8 BEST MANAGEMENT PRACTICES The City provides guidance for FSEs and other FOG producing users in the City to conform to BMPs for FOG control.These BMPs are practices and procedures that should be performed by FSEs to reduce the quantity of FOG discharged into the sanitary sewer system. Not all BMPs may be applicable to all users;therefore,the following should be used as a starting point for the development of individualized BMPs.These BMPs are described in Appendix H.2, and summarized below: • BMP 1- Employee Training and Awareness: This BMP is meant to adequately train employees and FOG producing establishments on the steps that should be taken to reduce FOG disposal into the sanitary sewer system.

Additionally,the use of drain screens is recommended by this BMP to capture food and other particles from being discharged into the sanitary sewer system.These screens should be cleaned frequently and emptied into the trash. • BMP 3-Spill Clean Up:This BMP summarizes the steps that should be taken by FOG producers when cleaning up spills.The use of"dry" methods should be used to the greatest extent possible. If"dry' methods are insufficient, water use and discharge to the sanitary sewer system should be limited as much as possible. • BMP 4- Equipment Cleaning and Maintenance: This BMP recommends that FOG producers should limit the discharge of FOG into the sanitary sewer system to the greatest extent practicable in the cleaning and maintenance of equipment. • BMP 5-Grease Handling and Disposal: This BMP requires that oils,grease, or other oily liquids (such as salad dressing) should not be discharged in large quantities into the sanitary sewer system. These materials should be recycled, if possible. • BMP 6-Grease Traps:This BMP recommends steps that should be taken by FOG producers for the installation and maintenance of grease traps. • BMP 7- Residential and Private Dwellings: It is important to note that not all FOG problems are caused by FSEs. In certain cities, residential FOG discharge may be a significant amount of the City's FOG production. For this reason, it is recommended that residential customers also adopt the aforementioned BMPs as applicable. 8.9 INSPECTION AND ENFORCEMENT PROCEDURES The City's FOG Control Plan provides provisions for the inspection of FOG producing facilities and the enforcement actions that should be taken by the City in the event of a violation of the provisions of the plan. 8.9.1 FOG Database The City currently performs inspections of all FSEs located within City boundaries.Table 8.2 lists the major FSEs in the City and their respective inspection recurrence. 8.9.2 Inspection The City currently inspects its major FSEs on an annual or biannual basis, see Table 8.2 for the FSE list.Through such inspections, the City can identify which FSEs conform to the City's existing grease trap requirements and set dates for compliance for those which do not conform with City June 2020 8-5 FAproj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\08.doc Table 8.2 FSE List Business Name Street Address ecurrence Ada's Fish House 558 Price St Annually ALFA Mobile Detailing 506 N.1st St Biannually All American Cafe 1053 Price St Annually Beachin Biscuits 783 Price St Annually Brad's Restaurant 209 Pomeroy Ave Annually Brook's Burgers 220 Five Cities Dr Annually Cal Fresh Market 555 Five Cities Dr Biannually Chipwrecked 246 Pomeroy Ave Annually Chop Street 779 Price St Annually Cliffs Resort 2757 Shell Beach Rd Annually Coco's Bakery Restaurant 412 Five Cities Dr Biannually Cool Cat Cafe 198 Pomeroy Ave Annually Cracked Crab 751 Price St Annually De Paulo&Sons 2665 Shell Beach Rd Annually Del's Pizzeria 1101 Price St Annually Denny's 611 Five Cities Dr Annually El Mirador 187 Pomeroy Ave Annually F.McLintock Salon 750 Mattie Rd Annually Fa 's Asian Fusion 222 Hinds Annually Flagship 1601 Price St Annually Gino's Pizza 539 Five Cities Dr Annually Golden Donuts 863 Oak Park Blvd. Annually Guiseppe's Cucina Italiana 891 Price St Annually Guiseppe's Express 800 Price St Annually Hapy 821 N.Oak Park Annually Hilton Garden Inn 601 James Way Annuallly Hoagie's Sandwiches 580 Cypress St Biannually Honeymoon Cafe 999 Price St Annually Hot Shots 250 Pomeroy Ave Annually Huckleberry's 300 Five Cities Dr Biannually Jack in the Box 334 Five Cities Dr Annually Kanpai Sushi 2665 Shell Beach Rd Biannually La Bode a 790 Price St Annually Lido at Dolphin Bay 2727 Shell Beach Rd Annually Los Amigos 690 Dolliver St. Annually McDonald's 350 Five Cities Dr Annually Meals on Wheels 780 Bello St. Annually Meat Market 841 Dolliver Biannually Mei's Chinese Restaurant 1759 Shell Beach Rd Annually Miller's 76 Station 542 Five Cities Dr Annually Mon Am! 230 Pomeroy Ave Annually Mo's BBQ 221 Pomeroy Ave Annually Oasis 1351 Price St Biannually Old West Cinnamon Rolls 861 Dolliver St Annually Oxford Suites 651 Five Cities Dr Annually Oyster Loft 101 Pomeroy Ave Annually Papi's 1090 Price St Biannually Pismo Beach Automotive 1001 Price St Biannually Pismo Bowl 277 Pomeroy Ave Biannually Pismo Brewing Company 500 Cypress St. Annually Pismo Coast RV Service 180 S.Dolliver St Annually Pismo Coast Village Grill 165 S.Dolliver St Annually Pismo Fish&Chips 505 Cypress St. Annually Pizmo 270 Pomeroy Ave Annually Rosa's Italian Restaurant 491 Price St Annually Sando's Deli 1255 Shell Beach Rd Annually Scotty's Bar&Grill 750 Price St Annually Sea Venture 100 Ocean View Ave Annually Seaside Cafe&Bakery 1327 Shell Beach Rd Biannually Shell Beach Brew House 1527 Shell Beach Rd Annually Shell Beach Liquor 601 Shell Beach Rd Annually Splash Cafe 197 Pomeroy Ave Annually Spyglass Restaurant 2703 Spyglass Dr Biannually St.Anthony's Hall 390 Bello Annually Surfside Donuts 603 Dolliver Annually Sushi Kokku 581 Five Cities Dr Annually Taco Bell 867 Oak Park Blvd. Annually Thai Elephant 561 Five Cities Dr Annually Thai Talay Restaurant 601 Price St Annually The Boardroom 160 Hinds#1 Annually Ventana Grill 2575 Price St Annually Willow Market 2131 Price St Annually Wool 's 175 Pomeroy Ave Annually WOW Yanagli Sushi 869 Oak Park Blvd. Annually Yana i Sushi&Grill 555 James Way Annually Zorro's Cafe&Cantina 927 Shell Beach Rd Annually Updated:10/14/2019 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\First Draft Comments\Restaurant List.xlsx standards. An example of the FOG and Storm Water form used during inspection is included in Appendix H.S.The City should continue with its current inspection procedures. 8.9.3 Enforcement Actions The City currently has a procedure in place for the enforcement of its existing FOG and grease trap requirements. It is anticipated that this procedure should be adequate for use with the FOG Control Plan, as well.Through the City's annual or biannual FSE inspections,violators of City standards are identified. A "Notice of Violation" is then issued to the violator(Appendix H.5).The violator is then given a time-frame for which they are to comply with the requirements of the notices that have been issued. Should the violator choose not to comply,then a non-compliance fine of an amount not to exceed $250 for each day the violation continues to exist is issued. 8.10 SOURCE CONTROL MEASURES It is expected that the City's existing discharge prohibitions, grease trap requirements, and inspection procedures, coupled with the additional recommendations provided in the FOG Control Plan (such as the implementation of BMPs by individual FSEs), should provide substantial success in terms of FOG source control. If, upon implementation of the FOG Control Plan and SSMP recommendations, it is determined that more stringent source control measures are needed, they may be implemented at the discretion of the City. June 2020 8-7 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\08.doc Chapter 9 SYSTEM EVALUATION AND CAPACITY ASSURANCE PLAN This chapter provides an evaluation of the City of Pismo Beach's (City's) sanitary sewer system facilities, identifies and proposes improvements for deficiencies, identifies design criteria, and provides a Capital Improvement Program (CIP) and schedule for improvements. 9.1 REGULATORY REQUIREMENT Order No. 2006-0003 requires that the City prepare and implement a CIP that will provide hydraulic capacity for peak dry weather flows as well as the appropriate design storm or wet weather event. The Sewer System Management Plan (SSMP) must address, at a minimum,the following: a. Evaluation. Actions needed to evaluate those portions of sanitary sewer system that are experiencing or contributing to a sanitary sewer overflow(SSO) discharge caused by hydraulic deficiency.The evaluation must provide estimates of peak flows (including flows from SSOs that escape from the system) associated with conditions similar to those causing overflow events, estimates of the capacity of key system components, hydraulic deficiencies (including components of the system with limiting capacity) and the major sources that contribute to the peak flows associated with overflow events; b. Design Criteria. Where design criteria do not exist or are deficient, undertake the evaluation identified in (a)above to establish appropriate design criteria; C. Capacity Enhancement Measures.The steps needed to establish a short-and long- term CIP to address identified hydraulic deficiencies, including prioritization, alternatives analysis, and schedules.The CIP may include increases in pipe size, 1/1 reduction programs, increases and redundancy in pumping capacity, and storage facilities.The CIP shall include an implementation schedule and shall identify sources of funding; and d. Schedule. The Enrollee shall develop a schedule of completion dates for all portions of the capital improvement program developed in (a) - (c) above. The schedule shall be reviewed and updated consistent with the SSMP review and update requirements as described in Section D.14 (of Order 2006-0003). 9.2 SYSTEM EVALUATION AND CAPACITY ASSURANCE PLAN The City of Pismo Beach previously completed Wastewater Collection System Master Plan, in 2000. The 2000 Master Plan recommended improvements to address the City's system deficiencies at that time and to recommend improvements to plan for future development. A copy of this Master Plan is included in the 2007 Sewer System Management Plan.The major priority projects identified in the Master Plan have been completed At the time of completion of the 2000 Master Plan, the City's average daily sewer discharge was 1.3 MGD with peak wet hour wet weather flows at about 6 mgd.These flows and projected flows were June 2020 9-1 FAproj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\09.doc used in developing the 2000 Master Plan's model. In 2006,the City completed a WWTP upgrade with a design capacity at 1.6 MGD and a 6.0 MGD peak flow. Since the completion of Collection System Master Plan and the WWTP upgrades, the City's average daily sewer discharge has decreased to 1.0 MGD or less (from 1.3 mgd early 2000s).The decrease in flows is primarily attributed to the water conservation efforts throughout the city as a result of the 2012-2016 drought impacts. With the completion of nearly most all the CIP projects identified in the 2000 Collections System Master Plant and the City wide decrease in wastewater flows is an indication that the City has capacity assurance in the system. 9.2.1 Analysis Method The City's sewer collection system was analyzed as part of the 2000 Master Plan with the aid of a sewer analysis computer program, Hydra Version 6,which was developed by Pizer, Inc. Hydra is a quasi-dynamic model, using Manning's equation to calculate system capacity. Two hydraulic computer models were developed to analyze the City's collection system. One hydraulic model was developed to analyze the City's gravity collection system, whereas the second model was developed to analyze the City's force mains and lift stations. These analyses resulted in the preparation of a comprehensive CIP in 2000. 9.2.2 Planning and Design Criteria The 2000 Master Plan established several criteria to model and evaluate the City's sewer system, as described in this section. For a more detailed account of the planning criteria used in the 2000 Master Plan, see Appendix I. 9.2.2.1 Flow Generation The 2000 Master Plan accounted for flows originating from several sources, including residential, hotel rooms, commercial, infiltration and inflow (1/1), RV Park, and Public Facilities. This is consistent with the requirements of Order No. 2006-0003.The average flows have since decreased over time. 9.2.2.2 Infiltration and Inflow The City historically experiences high peak flows during periods of wet weather as a result of 1/1. For this reason,the 2000 Master Plan included an 1/1 analysis.Through the analysis, it was determined that significant inflow reductions were possible,through video inspection and other mitigation measures.Thru normal consistent maintenance efforts,the City collections staff has no reason to believe that 1/1 has increased over time. 9.2.2.3 Peak Conditions and Peaking Factors The 2000 Master Plan established historical and design peaking factors to be used in the evaluation and planning of future facilities for the City's sewer collection system (Table 9.1).The peak conditions of interest are summarized as follows. June 2020 9-2 FAproj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\09.doc • Average Annual Flow(AAF): Obtained by dividing the total flow conveyed by the City's collection system in one year by 365 days. Other peak conditions are derived by multiplying the AAF by a peaking factor. • Peak Day Dry Weather Flow(PDF):The maximum flow occurring in one day during the dry season. In the City,this condition normally occurs during the Fourth of July weekend. • Peak Hour Wet Weather Flow(PHWWF):The maximum flow rate that occurs in a single hour during wet weather. 1/1 contributes a substantial amount to this flow rate in the City. • Average Day Maximum Month Dry and Wet Weather Flows:These flows reflect the maximum flow rate during the peak months of summer and winter, respectively. Table 9.1 2000 Master Plan Peaking Factor Summary Sewer System Management Plan City of Pismo Beach Design Peaking Historical Peaking Factor Factor Peak Flow Condition (City-Wide) (City-Wide)Z Average Annual Flow (AAF) Peak Day Dry Weather Flow 1.49 1.50 (PDF) Peak Hour Wet Weather Flow 2.67 3.00 (PHWWF) Average Day Maximum Month 1.07 1.20 Dry Weather Flow Average Day Maximum Month 1.35 1.35 Wet Weather Flow Notes: 1. Source: City of Pismo Beach Collection System Master Plan, February 2000. 2. Design peaking factors were used in the master planning effort. 9.2.2.4 Flow Depth Criteria Flow depth criteria were established as part of the master planning effort.These criteria are typically expressed in terms of the maximum flow depth the pipe diameter(d/D) ratio. Many municipalities establish variable d/D criteria based on the size of pipe considered. For simplicity, however,the 2000 Master Plan established a single maximum d/D ratio of 0.70 for gravity pipes under build out conditions. June 2020 9-3 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\09.doc 9.2.2.5 Flow Coefficients The 2000 Master Plan established flow coefficients to determine average flow for the City (Table 9.2).There are several methods for the determination of flow for municipalities.The units for the flow coefficients used in the 2000 Master Plan varied depending on the type of user. For example,for residential users the flow coefficient was in the units of gallons per day per person, whereas the flow coefficient for hotel rooms was in the units of gallons per day per room. Table 9.2 Master Plan Flow Coefficients Sewer System Management Plan City of Pismo Beach Unit Average Flow Coefficient Source of Flow Units (gal/day/unit) Residential persons 95 Hotel Rooms rooms 100 Commercial Square feet 0.10 RV Park Number of RVs 50 Public Facility' N/A N/A Infiltration/Inflow' N/A N/A Notes: 1. Source: City of Pismo Beach Collection System Master Plan, February 2000 2. Flows for 1/1 and Public Facilities were not calculated based on flow coefficients. 9.2.2.6 Pipeline Velocity Minimum and maximum gravity pipeline velocities were established as part of the 2000 Master Plan in order to establish proper performance evaluation criteria for the sewer collection system. The established minimum gravity pipeline velocity of 2 ft/s is a standard minimum velocity for the maintenance of self cleaning velocities in a sewer collection system. The maximum allowable gravity pipeline velocity, 10 ft/s,was established in order to eliminate any potential pipeline scour or other problems associated with high pipeline velocities.Additionally, minimum and maximum pipeline velocities of 2 ft/s and 5 ft/s have been established for the analysis and design of force mains, respectively. 9.2.3 Evaluation The 2000 Master Plan utilized two hydraulic computer models to analyze the City's collection system. One model was constructed for the City's gravity collection system,whereas the other model was created for the City's force mains and lift stations. In order to construct the computer models of the City's collection system,the arrangement of the City's system was laid out for each model using AutoCAD and then imported into the Hydra Version June 2020 9-4 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\09.doc 6 computer model.The Hydra program includes "GIS Master,"which is an AutoCAD "add-on"tool that facilitates the assembly of the hydraulic model. Input data associated with the model included pipe size, pipe length, upstream and downstream invert elevations, and ground elevations. Following the digitization of the City's collection system, flows were allocated to the appropriate areas of the collection system. Model runs were then conducted using the Hydra modeling software and the performance of the system was evaluated based on the criteria established in the 2000 Master Plan. 9.2.4 Capacity Enhancement Measures The 2000 Master Plan identified existing system deficiencies and recommended improvements to plan for future development. In conjunction with the 2000 Master Plan, most projects have been and completed prior to the MP completion. Of the lift station projects from the 2000 CIP, 4 encompassed complete removal and replacement of the old lift station.The newly constructed lift stations, since 2000, include Pismo Oaks, Addie Street, Price Street and Five Cities (to be completed end of Fall 2019). Although most project have been completed, a new CIP has been developed as part of this SSMP update. The projects include Lift Station rehabilitation and upgrades. Most of the components identified are from staff observations through normal maintenance efforts on the system. As a result of operational observations during a 2014 spill,the wastewater staff now redirects flows in order to not overload the manifold force main serving the Vista Del Mar Lift Station.The flow from lift stations Sunset Palisades, Spyglass, and St Andrews are redirected from the shell beach road FM to the Mattie Rd FM during storm events, in order to keep the head pressure off of the flow of Vista Del Mar lift station. This is achieved through existing valves and piping in the intersection of Shell Beach road and Spyglass. 9.2.4.1 2000 Gravity Collection System Deficiencies Although a detailed condition assessment has not been performed,the wastewater staff has recommended (through field observations) the rehabilitation of 19 manholes in upper Maddie Road. There are no known capacity issues as a result of the existing manhole deteriorations. 9.2.4.2 2019 Lift Station CIP Thru on-going maintenance efforts by wastewater staff, a lift Station CIP was developed.This CIP should be implemented in the 1-5-year timeframe.There are no know system deficiencies as a result of the projects identified in the CIP. 9.2.4.2.1 Addie Street Lift Station The Lift station was completely replaced in 2003 and has functioned well over the years.At the time of the 2000 Master Plan,the Addie Street lift station was both the largest and oldest in the June 2020 9-5 FAproj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\09.doc City. In addition,this lift station was one of the main causes of SSOs and other capacity issues within the City, as well as odor issues. The lift station was re-built to address the capacity and foul-air issues. Since its construction,the City has not had any more additional problems with capacity or odor. However,the lift station has corrosion issues with key components which need to be addressed. The sluice gates controlling inflow into the two wet wells and the isolation sluice gate between the wet well chambers have extensive corrosion and require replacement. In addition,the gate stem, stem guide and operating nuts will need to be replaced with the gates. It is recommended the City replace the components in the wet well with a higher quality corrosion resistant material such as stainless steel to lengthen the lifespan of the gates.The maintenance improvements in the wet well will also include replacing the old, degraded foul-air piping with flanged PVC for better corrosion resistance. Given the proximity to the ocean,the pump building is showing signs of corrosion from the ocean air. The City provided feedback for replacing the building skylights where there is noticeable corrosion on the sheet metal. 9.2.4.2.2 Freeway Foothills Lift Station Major maintenance was completed for the Freeway Foothills lift station in 2019. However,there several long-term items identified for improvement. The City staff with a field observation of the Lift Station resulted in the development of a few upgrades.The proposed upgrades include the complete replacement of pump electrical equipment and SCADA panel. A new permanent stand-by generator is to be installed to replace the mobile generator on-site.The installation of a VFD will be considered with the electrical upgrade. In addition, a potable water source (for washdown purposes) is needed for the proper maintenance of the LS. It is recommended that the City install a perimeter fence around the site, an area light for the City's maintenance crew and replace the deteriorated on-site pavement. 9.2.4.2.3 Vista Del Mar Lift Station The Vista Del Mar lift station serves the Shell Beach planning area. The lift station was upgraded in 1995, and after it was placed in service,the new Cornell pumps began to exhibit cavitation problems.This problem was mitigated by injecting air into the pump system, but the system uses small diameter piping that frequently clogs. Additionally, operations staff have reported that the pumps routinely air lock. Since the upgrade,the City has recoated the inlet manhole, wet well and the piping in the drywell. Float level controls were installed in the wet well during the recoating. June 2020 9-6 FAproj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\09.doc The proposed improvements for the updated CIP include a complete electrical upgrade with VFDs and new electrical cabinet, new permanent stand-by generator with a new ceiling slab and hatch. Upsizing the suction line from 4-inch to 8-inch has been rolled over into the updated CIP. 9.2.4.2.4 Spyglass Lift Station The Spyglass lift station serves the Spyglass, St.Andrews, and Spindrift planning areas. The station was 26 years old at the time of the 2000 Master Plan but is adequately sized for build-out.The City's maintenance project included recoating the wet well, dry well and piping, installing new float level controls, replacing the cast-iron discharge piping with PVC and installing a new permanent stand-by generator and building. The CIP identified for Spyglass are to provide a complete electrical upgrade with a new electrical enclosure cabinet for both MCC and SCADA and for an VFD on the pumps for level control in the wet well. Replacement of the manhole rim and concrete collar for the wet well as well as a replacement FRP hatch for the dry well access. 9.2.4.2.5 PG&E Lift Station The PG&E lift station serves a small area within the Pismo Heights and Industrial planning zones. Due in part to small flows,the station functioned adequately during the peak flows at the time of the 2000 Master Plan. Operation staff periodically replace pumps and perform other maintenance functions on the station.The most recent improvements completed are recoating the wet well and installing float level controls and electrical upgrades. The proposed improvements for the PG&E lift station are the relocation of the control panel from the dry well to the electrical backboard.The electrical backboard will also be replaced. For the site, a new security gate along with an area light and the pavement will be rehabilitated. 9.2.4.2.6 Saint Andrews Lift Station The Saint Andrews lift station serves a small residential area in Saint Andrews planning area. Similar to the PG&E lift station, the station handles minor flows. The lift station was built with a combination wet/dry well with a separating plated set in the well to isolate the dry well from the effluent sewage. The proposed improvements to Saint Andrews include rehabilitating the wet well and converting it into a traditional wet well operation with by- pass.The lid and hatch on the existing well will be replace after the well is converted to a formal wet well. A formal dry well with new pumps will be installed adjacent to the wet well. A new valve vault will be installed in the grass area adjacent to the street.The improvements will also include a complete electrical upgrade and new electrical cabinet. June 2020 9-7 FAproj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\09.doc 9.2.4.2.7 Sunset Palisades Lift Station The Sunset Palisades lift station serves residential neighborhoods with the Ontario Ridge,Sunset Palisades, and South Palisades planning areas. In June 1999,the lift station was upgraded to address capacity and reliability problems. Other improvements completed include recoating the wet well, dry well and discharge piping, lining the cast iron discharge piping, and installing float level controls in the wet well. The proposed improvements include replacing the old antenna and removing the old transformer pad. 9.2.5 Schedule 9.2.5.1 2006 to 2016 Updated Capital Improvement Program Table 9.3 summarizes the City's most recently completed CIP and improvement schedule.

Maintain relevant information that can be used to establish and prioritize appropriate SSMP activities; b. Monitor the implementation and, where appropriate, measure the effectiveness of each element of the SSMP; C. Assess the success of the preventative maintenance program; d. Update program elements, as appropriate, based on monitoring or performance evaluations; and e. Identify and illustrate SSO trends, including frequency, location, and volume. 10.2 SSMP INFORMATION MAINTENANCE PROGRAM The City maintains and tracks information related to the SSMP and SSO's from the resources provided on the CIWQS website.The reports are downloaded off the website into an excel format which is modified for the City's purpose of easily tracking the performance of the SSMP through the requirements set out in section 3 of this Chapter.The CIWQS's Public Sewage Spill Incident Map provides an overview of the City's SSO's locations with attributes linked to SSO point data (i.e. spill volume, category no., etc.). The City maintains their own GIS collection system map based off construction improvements.They track"hot spots" and FOG pipelines through GIS and compile an excel table for frequent cleaning intervals of all problem areas. Information collected from experienced maintenance crews and CIQWS reports are used to update the list when new"hot spots" emerge. The City maintains information that is appropriate to the SSMP through an SSO tracking table (Appendix 1).The information recorded in the SSO tracking table allows the City to draw conclusions and trends related to SSOs and the performance of the SSMP.The table is kept in up to date in Microsoft excel and is easily accessible for individuals involved in the SSMP. June 2020 10-1 FAproj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\10.doc 10.3 PERFORMANCE MEASURMENT The City's SSMP database tracks a few key performance indicators that are used to measure the progress of the SSMP implementation and the performance of the City's sanitary sewer collection system. Some key performance indicators considered for tracking by the City are: • Number of Service Calls, blockages, and SSOs over a one year period; • SSO events by cause; • Total spillage volume and total volume contained; • SSO events by location within the City. • Volume of sewage discharged to surface water 10.4 PERFORMANCE EVALUATION The City's performance data is based on the performance measurements listed in Section 10.3. Table 10.1 shows an in-depth analysis of the City's SSMP over the last five years and Table 10.2 provides the number of annual SSO's and their associated category level since 2007. The categories assigned to SSO's are based on the requirements set in Order No. WQ 2013-0058 EXEC. As identified in the City's SSMP database,the leading cause of SSO's are debris blockages which account for approximately 30%of the City's SSO's since 2007. Debris blockages are considered episodic and are generally not related to maintenance performance issues. Typically, debris blockages are caused by non-dissolvable materials like disposable wipes, rags, feminine hygiene products and cement in the system. The City has recorded an SSO due to debris blockage every year for the past five years, with the exception of 2017. Recorded debris blockages range from rags,to construction related, or are sometimes unidentified. The second leading cause is mechanical/electrical failure with old/failing equipment and piping. Mechanical/electrical failure accounts for another 30%of the City's SSO's. Equipment and piping failures are common at ARV's and valves.The City is reviewing its Engineering Standards for improving their piping and valve standards.The City will review and update its CIP to proactively replace old appurtenances before failure occurs.

In 2014,the City experienced a higher than usual rate of failed air release valve appurtenances for the lift station force mains.The failed components were replaced after the leaks were isolated. It is recommended the City review their Engineering Standards for ARV's to prevent future leaks in the ARV's and piping. In addition, 2014 had two SSO's caused by maintenance crews during routine cleaning operations. 10.5 SSMP MODIFICATIONS Based on the Performance Evaluation conducted in Section 10.4,the City has been meeting the performance standards in the SSMP. A plan for modifying the City's standards and infrastructure to improve the SSMP's performance it summarized below. Due to the lack of cleaning maintenance related SSO's,the City will continue with their procedure for maintaining their sewer pipe infrastructure. Other proactive options, (i.e. CCTV)will be explored in aiding the determination of new "hot spots" and FOG problem areas.The City will continue to update their GIS database and cleaning schedule tables based off information from field observations and CCTV'ing. The City is in the process of updating its CIP, as part of the SSMP update,to address maintenance issues in the City owned lift stations and piping infrastructure. Data from previous SSO's is cataloged so the City can determine the proper improvements needed to prevent future SSO's on top of the routine replacement of aging sewer system equipment. Updates to existing infrastructure will include increase capacity in known problem areas where past overflows have occurred.The updates to the CIP are summarized in Chapter 9 of this SSMP. The City is currently reviewing and updating their Engineering Standards. Standards for dissimilar materials in ARV vaults is being discussed for better alternatives to prevent future failures in the ARV's and connecting pipes. The City's FOG related blockages have decreased in recent years due to the City's public outreach and frequent cleaning of FOG "hot spots" in the collection system. FOG blockages that occur in previously unrecorded "hot spots" are added to the Preventive Maintenance Program for more frequent cleaning. However, debris blockages have occurred at a consistent rate in recent years. The City will continue with its FOG public outreach program to continue reducing improper disposal of oils, grease and maintenance for grease traps and inceptors. In addition,the prohibition of discharging non-dissolvable materials into the collection system will be added into the City's updated outreach program. For subsequent years,the City will conduct an annual review of the SSMP performance measurements and make modifications to the program.All program updates and modifications are June 2020 10-4 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\10.doc approved by the City's Authorized Representative and incorporated into the SSMP report,when necessary. Formalizing modifications will be part of updating the SSMP every five years. The City will determine the need to update its SSMP more frequently based on the results of the audits and performance of its collection system. If there are major changes to the SSMP, it will be re-certified by the City's Authorized Representative on CIWQS.The costs associated with the SSMP updates should be budgeted for by the City and included in the City's CIP.

June 2020 12-2 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\12.doc City of Pismo Beach Sewer System Management Plan APPENDIX A - SWRCB ORDER NO. 2006-0003 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\Appendices\App.doc STATE WATER RESOURCES CONTROL BOARD ORDER NO. 2006-0003-DWQ STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS FOR SANITARY SEWER SYSTEMS The State Water Resources Control Board, hereinafter referred to as "State Water Board", finds that: 1. All federal and state agencies, municipalities, counties, districts, and other public entities that own or operate sanitary sewer systems greater than one mile in length that collect and/or convey untreated or partially treated wastewater to a publicly owned treatment facility in the State of California are required to comply with the terms of this Order. Such entities are hereinafter referred to as "Enrollees". 2. Sanitary sewer overflows (SSOs) are overflows from sanitary sewer systems of domestic wastewater, as well as industrial and commercial wastewater, depending on the pattern of land uses in the area served by the sanitary sewer system. SSOs often contain high levels of suspended solids, pathogenic organisms, toxic pollutants, nutrients, oxygen-demanding organic compounds, oil and grease and other pollutants. SSOs may cause a public nuisance, particularly when raw untreated wastewater is discharged to areas with high public exposure, such as streets or surface waters used for drinking, fishing, or body contact recreation. SSOs may pollute surface or ground waters, threaten public health, adversely affect aquatic life, and impair the recreational use and aesthetic enjoyment of surface waters. 3. Sanitary sewer systems experience periodic failures resulting in discharges that may affect waters of the state. There are many factors (including factors related to geology, design, construction methods and materials, age of the system, population growth, and system operation and maintenance), which affect the likelihood of an SSO. A proactive approach that requires Enrollees to ensure a system-wide operation, maintenance, and management plan is in place will reduce the number and frequency of SSOs within the state. This approach will in turn decrease the risk to human health and the environment caused by SSOs. 4. Major causes of SSOs include: grease blockages, root blockages, sewer line flood damage, manhole structure failures, vandalism, pump station mechanical failures, power outages, excessive storm or ground water inflow/infiltration, debris blockages, sanitary sewer system age and construction material failures, lack of proper operation and maintenance, insufficient capacity and contractor- caused damages. Many SSOs are preventable with adequate and appropriate facilities, source control measures and operation and maintenance of the sanitary sewer system. State Water Resources Control Board Order No. 2006-0003-DWQ Page 2 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 SEWER SYSTEM MANAGEMENT PLANS 5. To facilitate proper funding and management of sanitary sewer systems, each Enrollee must develop and implement a system-specific Sewer System Management Plan (SSMP). To be effective, SSMPs must include provisions to provide proper and efficient management, operation, and maintenance of sanitary sewer systems, while taking into consideration risk management and cost benefit analysis. Additionally, an SSMP must contain a spill response plan that establishes standard procedures for immediate response to an SSO in a manner designed to minimize water quality impacts and potential nuisance conditions. 6. Many local public agencies in California have already developed SSMPs and implemented measures to reduce SSOs. These entities can build upon their existing efforts to establish a comprehensive SSMP consistent with this Order. Others, however, still require technical assistance and, in some cases, funding to improve sanitary sewer system operation and maintenance in order to reduce SSOs. 7. SSMP certification by technically qualified and experienced persons can provide a useful and cost-effective means for ensuring that SSMPs are developed and implemented appropriately. 8. It is the State Water Board's intent to gather additional information on the causes and sources of SSOs to augment existing information and to determine the full extent of SSOs and consequent public health and/or environmental impacts occurring in the State. 9. Both uniform SSO reporting and a centralized statewide electronic database are needed to collect information to allow the State Water Board and Regional Water Quality Control Boards (Regional Water Boards) to effectively analyze the extent of SSOs statewide and their potential impacts on beneficial uses and public health. The monitoring and reporting program required by this Order and the attached Monitoring and Reporting Program No. 2006-0003-DWQ, are necessary to assure compliance with these waste discharge requirements (WDRs). 10. Information regarding SSOs must be provided to Regional Water Boards and other regulatory agencies in a timely manner and be made available to the public in a complete, concise, and timely fashion. 11.Some Regional Water Boards have issued WDRs or WDRs that serve as National Pollution Discharge Elimination System (NPDES) permits to sanitary sewer system owners/operators within their jurisdictions. This Order establishes minimum requirements to prevent SSOs. Although it is the State Water Board's intent that this Order be the primary regulatory mechanism for sanitary sewer systems statewide, Regional Water Boards may issue more stringent or more State Water Resources Control Board Order No. 2006-0003-DWQ Page 3 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 prescriptive WDRs for sanitary sewer systems. Upon issuance or reissuance of a Regional Water Board's WDRs for a system subject to this Order, the Regional Water Board shall coordinate its requirements with stated requirements within this Order, to identify requirements that are more stringent, to remove requirements that are less stringent than this Order, and to provide consistency in reporting. REGULATORY CONSIDERATIONS 12. California Water Code section 13263 provides that the State Water Board may prescribe general WDRs for a category of discharges if the State Water Board finds or determines that: • The discharges are produced by the same or similar operations; • The discharges involve the same or similar types of waste; • The discharges require the same or similar treatment standards; and • The discharges are more appropriately regulated under general discharge requirements than individual discharge requirements. This Order establishes requirements for a class of operations, facilities, and discharges that are similar throughout the state. 13.The issuance of general WDRs to the Enrollees will: a) Reduce the administrative burden of issuing individual WDRs to each Enrollee; b) Provide for a unified statewide approach for the reporting and database tracking of SSOs; c) Establish consistent and uniform requirements for SSMP development and implementation; d) Provide statewide consistency in reporting; and e) Facilitate consistent enforcement for violations. 14.The beneficial uses of surface waters that can be impaired by SSOs include, but are not limited to, aquatic life, drinking water supply, body contact and non- contact recreation, and aesthetics. The beneficial uses of ground water that can be impaired include, but are not limited to, drinking water and agricultural supply. Surface and ground waters throughout the state support these uses to varying degrees. 15.The implementation of requirements set forth in this Order will ensure the reasonable protection of past, present, and probable future beneficial uses of water and the prevention of nuisance. The requirements implement the water quality control plans (Basin Plans) for each region and take into account the environmental characteristics of hydrographic units within the state. Additionally, the State Water Board has considered water quality conditions that could reasonably be achieved through the coordinated control of all factors that affect State Water Resources Control Board Order No. 2006-0003-DWQ Page 4 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 water quality in the area, costs associated with compliance with these requirements, the need for developing housing within California, and the need to develop and use recycled water. 16.The Federal Clean Water Act largely prohibits any discharge of pollutants from a point source to waters of the United States except as authorized under an NPDES permit. In general, any point source discharge of sewage effluent to waters of the United States must comply with technology-based, secondary treatment standards, at a minimum, and any more stringent requirements necessary to meet applicable water quality standards and other requirements. Hence, the unpermitted discharge of wastewater from a sanitary sewer system to waters of the United States is illegal under the Clean Water Act. In addition, many Basin Plans adopted by the Regional Water Boards contain discharge prohibitions that apply to the discharge of untreated or partially treated wastewater. Finally, the California Water Code generally prohibits the discharge of waste to land prior to the filing of any required report of waste discharge and the subsequent issuance of either WDRs or a waiver of WDRs. 17.California Water Code section 13263 requires a water board to, after any necessary hearing, prescribe requirements as to the nature of any proposed discharge, existing discharge, or material change in an existing discharge. The requirements shall, among other things, take into consideration the need to prevent nuisance. 18.California Water Code section 13050, subdivision (m), defines nuisance as anything which meets all of the following requirements: a. Is injurious to health, or is indecent or offensive to the senses, or an obstruction to the free use of property, so as to interfere with the comfortable enjoyment of life or property. b. Affects at the same time an entire community or neighborhood, or any considerable number of persons, although the extent of the annoyance or damage inflicted upon individuals may be unequal. c. Occurs during, or as a result of, the treatment or disposal of wastes. 19.This Order is consistent with State Water Board Resolution No. 68-16 (Statement of Policy with Respect to Maintaining High Quality of Waters in California) in that the Order imposes conditions to prevent impacts to water quality, does not allow the degradation of water quality, will not unreasonably affect beneficial uses of water, and will not result in water quality less than prescribed in State Water Board or Regional Water Board plans and policies. 20.The action to adopt this General Order is exempt from the California Environmental Quality Act (Public Resources Code §21000 et seq.) because it is an action taken by a regulatory agency to assure the protection of the environment and the regulatory process involves procedures for protection of the environment. (Cal. Code Regs., tit. 14, §15308). In addition, the action to adopt State Water Resources Control Board Order No. 2006-0003-DWQ Page 5 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 this Order is exempt from CEQA pursuant to Cal.Code Regs., title 14, §15301 to the extent that it applies to existing sanitary sewer collection systems that constitute "existing facilities" as that term is used in Section 15301, and §15302, to the extent that it results in the repair or replacement of existing systems involving negligible or no expansion of capacity. 21.The Fact Sheet, which is incorporated by reference in the Order, contains supplemental information that was also considered in establishing these requirements. 22.The State Water Board has notified all affected public agencies and all known interested persons of the intent to prescribe general WDRs that require Enrollees to develop SSMPs and to report all SSOs. 23.The State Water Board conducted a public hearing on February 8, 2006, to receive oral and written comments on the draft order. The State Water Board received and considered, at its May 2, 2006, meeting, additional public comments on substantial changes made to the proposed general WDRs following the February 8, 2006, public hearing. The State Water Board has considered all comments pertaining to the proposed general WDRs. IT IS HEREBY ORDERED, that pursuant to California Water Code section 13263, the Enrollees, their agents, successors, and assigns, in order to meet the provisions contained in Division 7 of the California Water Code and regulations adopted hereunder, shall comply with the following: A. DEFINITIONS 1. Sanitary sewer overflow (SSO) - Any overflow, spill, release, discharge or diversion of untreated or partially treated wastewater from a sanitary sewer system.

Untreated or partially treated wastewater— Any volume of waste discharged from the sanitary sewer system upstream of a wastewater treatment plant headworks. 6. Satellite collection system — The portion, if any, of a sanitary sewer system owned or operated by a different public agency than the agency that owns and operates the wastewater treatment facility to which the sanitary sewer system is tributary. 7. Nuisance - California Water Code section 13050, subdivision (m), defines nuisance as anything which meets all of the following requirements: a. Is injurious to health, or is indecent or offensive to the senses, or an obstruction to the free use of property, so as to interfere with the comfortable enjoyment of life or property. b. Affects at the same time an entire community or neighborhood, or any considerable number of persons, although the extent of the annoyance or damage inflicted upon individuals may be unequal. c. Occurs during, or as a result of, the treatment or disposal of wastes. B. APPLICATION REQUIREMENTS 1. Deadlines for Application — All public agencies that currently own or operate sanitary sewer systems within the State of California must apply for coverage under the general WDRs within six (6) months of the date of adoption of the general WDRs. Additionally, public agencies that acquire or assume responsibility for operating sanitary sewer systems after the date of adoption of this Order must apply for coverage under the general WDRs at least three (3) months prior to operation of those facilities. 2. Applications under the general WDRs — In order to apply for coverage pursuant to the general WDRs, a legally authorized representative for each agency must submit a complete application package. Within sixty (60) days of adoption of the general WDRs, State Water Board staff will send specific instructions on how to State Water Resources Control Board Order No. 2006-0003-DWQ Page 7 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 apply for coverage under the general WDRs to all known public agencies that own sanitary sewer systems. Agencies that do not receive notice may obtain applications and instructions online on the Water Board's website. 3. Coverage under the general WDRs — Permit coverage will be in effect once a complete application package has been submitted and approved by the State Water Board's Division of Water Quality. C. PROHIBITIONS 1. Any SSO that results in a discharge of untreated or partially treated wastewater to waters of the United States is prohibited. 2. Any SSO that results in a discharge of untreated or partially treated wastewater that creates a nuisance as defined in California Water Code Section 13050(m) is prohibited. D. PROVISIONS 1. The Enrollee must comply with all conditions of this Order. Any noncompliance with this Order constitutes a violation of the California Water Code and is grounds for enforcement action. 2. It is the intent of the State Water Board that sanitary sewer systems be regulated in a manner consistent with the general WDRs. Nothing in the general WDRs shall be: (i) Interpreted or applied in a manner inconsistent with the Federal Clean Water Act, or supersede a more specific or more stringent state or federal requirement in an existing permit, regulation, or administrative/judicial order or Consent Decree; (ii) Interpreted or applied to authorize an SSO that is illegal under either the Clean Water Act, an applicable Basin Plan prohibition or water quality standard, or the California Water Code; (iii) Interpreted or applied to prohibit a Regional Water Board from issuing an individual NPDES permit or WDR, superseding this general WDR, for a sanitary sewer system, authorized under the Clean Water Act or California Water Code; or (iv) Interpreted or applied to supersede any more specific or more stringent WDRs or enforcement order issued by a Regional Water Board. 3. The Enrollee shall take all feasible steps to eliminate SSOs. In the event that an SSO does occur, the Enrollee shall take all feasible steps to contain and mitigate the impacts of an SSO. 4. In the event of an SSO, the Enrollee shall take all feasible steps to prevent untreated or partially treated wastewater from discharging from storm drains into State Water Resources Control Board Order No. 2006-0003-DWQ Page 8 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 flood control channels or waters of the United States by blocking the storm drainage system and by removing the wastewater from the storm drains. 5. All SSOs must be reported in accordance with Section G of the general WDRs. 6. In any enforcement action, the State and/or Regional Water Boards will consider the appropriate factors under the duly adopted State Water Board Enforcement Policy. And, consistent with the Enforcement Policy, the State and/or Regional Water Boards must consider the Enrollee's efforts to contain, control, and mitigate SSOs when considering the California Water Code Section 13327 factors. In assessing these factors, the State and/or Regional Water Boards will also consider whether: (i) The Enrollee has complied with the requirements of this Order, including requirements for reporting and developing and implementing a SSMP; (ii) The Enrollee can identify the cause or likely cause of the discharge event; (iii)There were no feasible alternatives to the discharge, such as temporary storage or retention of untreated wastewater, reduction of inflow and infiltration, use of adequate backup equipment, collecting and hauling of untreated wastewater to a treatment facility, or an increase in the capacity of the system as necessary to contain the design storm event identified in the SSMP. It is inappropriate to consider the lack of feasible alternatives, if the Enrollee does not implement a periodic or continuing process to identify and correct problems. (iv)The discharge was exceptional, unintentional, temporary, and caused by factors beyond the reasonable control of the Enrollee; (v) The discharge could have been prevented by the exercise of reasonable control described in a certified SSMP for: • Proper management, operation and maintenance; • Adequate treatment facilities, sanitary sewer system facilities, and/or components with an appropriate design capacity, to reasonably prevent SSOs (e.g., adequately enlarging treatment or collection facilities to accommodate growth, infiltration and inflow (I/I), etc.); • Preventive maintenance (including cleaning and fats, oils, and grease (FOG) control); • Installation of adequate backup equipment; and • Inflow and infiltration prevention and control to the extent practicable. (vi)The sanitary sewer system design capacity is appropriate to reasonably prevent SSOs. State Water Resources Control Board Order No. 2006-0003-DWQ Page 9 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 (vii) The Enrollee took all reasonable steps to stop and mitigate the impact of the discharge as soon as possible. 7. When a sanitary sewer overflow occurs, the Enrollee shall take all feasible steps and necessary remedial actions to 1) control or limit the volume of untreated or partially treated wastewater discharged, 2) terminate the discharge, and 3) recover as much of the wastewater discharged as possible for proper disposal, including any wash down water. The Enrollee shall implement all remedial actions to the extent they may be applicable to the discharge and not inconsistent with an emergency response plan, including the following: (i) Interception and rerouting of untreated or partially treated wastewater flows around the wastewater line failure; (ii) Vacuum truck recovery of sanitary sewer overflows and wash down water; (iii) Cleanup of debris at the overflow site; (iv) System modifications to prevent another SSO at the same location; (v) Adequate sampling to determine the nature and impact of the release; and (vi) Adequate public notification to protect the public from exposure to the SSO. 8. The Enrollee shall properly, manage, operate, and maintain all parts of the sanitary sewer system owned or operated by the Enrollee, and shall ensure that the system operators (including employees, contractors, or other agents) are adequately trained and possess adequate knowledge, skills, and abilities. 9. The Enrollee shall allocate adequate resources for the operation, maintenance, and repair of its sanitary sewer system, by establishing a proper rate structure, accounting mechanisms, and auditing procedures to ensure an adequate measure of revenues and expenditures. These procedures must be in compliance with applicable laws and regulations and comply with generally acceptable accounting practices. 10.The Enrollee shall provide adequate capacity to convey base flows and peak flows, including flows related to wet weather events. Capacity shall meet or exceed the design criteria as defined in the Enrollee's System Evaluation and Capacity Assurance Plan for all parts of the sanitary sewer system owned or operated by the Enrollee. 11.The Enrollee shall develop and implement a written Sewer System Management Plan (SSMP) and make it available to the State and/or Regional Water Board upon request. A copy of this document must be publicly available at the Enrollee's office and/or available on the Internet. This SSMP must be approved by the Enrollee's governing board at a public meeting. State Water Resources Control Board Order No. 2006-0003-DWQ Page 10 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 12.In accordance with the California Business and Professions Code sections 6735, 7835, and 7835.1, all engineering and geologic evaluations and judgments shall be performed by or under the direction of registered professionals competent and proficient in the fields pertinent to the required activities. Specific elements of the SSMP that require professional evaluation and judgments shall be prepared by or under the direction of appropriately qualified professionals, and shall bear the professional(s)' signature and stamp. 13.The mandatory elements of the SSMP are specified below. However, if the Enrollee believes that any element of this section is not appropriate or applicable to the Enrollee's sanitary sewer system, the SSMP program does not need to address that element.

The plan shall include a time schedule for implementing the short- and long-term plans plus a schedule for developing the funds needed for the capital improvement plan; (d) Provide training on a regular basis for staff in sanitary sewer system operations and maintenance, and require contractors to be appropriately trained; and State Water Resources Control Board Order No. 2006-0003-DWQ Page 12 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 (e) Provide equipment and replacement part inventories, including identification of critical replacement parts. (v) Design and Performance Provisions: (a) Design and construction standards and specifications for the installation of new sanitary sewer systems, pump stations and other appurtenances; and for the rehabilitation and repair of existing sanitary sewer systems; and (b) Procedures and standards for inspecting and testing the installation of new sewers, pumps, and other appurtenances and for rehabilitation and repair projects. (vi) Overflow Emergency Response Plan - Each Enrollee shall develop and implement an overflow emergency response plan that identifies measures to protect public health and the environment. At a minimum, this plan must include the following: (a) Proper notification procedures so that the primary responders and regulatory agencies are informed of all SSOs in a timely manner; (b) A program to ensure an appropriate response to all overflows; (c) Procedures to ensure prompt notification to appropriate regulatory agencies and other potentially affected entities (e.g. health agencies, Regional Water Boards, water suppliers, etc.) of all SSOs that potentially affect public health or reach the waters of the State in accordance with the MRP. All SSOs shall be reported in accordance with this MRP, the California Water Code, other State Law, and other applicable Regional Water Board WDRs or NPDES permit requirements. The SSMP should identify the officials who will receive immediate notification; (d) Procedures to ensure that appropriate staff and contractor personnel are aware of and follow the Emergency Response Plan and are appropriately trained; (e) Procedures to address emergency operations, such as traffic and crowd control and other necessary response activities; and (f) A program to ensure that all reasonable steps are taken to contain and prevent the discharge of untreated and partially treated wastewater to waters of the United States and to minimize or correct any adverse impact on the environment resulting from the SSOs, including such accelerated or additional monitoring as may be necessary to determine the nature and impact of the discharge. State Water Resources Control Board Order No. 2006-0003-DWQ Page 13 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 (vii) FOG Control Program: Each Enrollee shall evaluate its service area to determine whether a FOG control program is needed. If an Enrollee determines that a FOG program is not needed, the Enrollee must provide justification for why it is not needed. If FOG is found to be a problem, the Enrollee must prepare and implement a FOG source control program to reduce the amount of these substances discharged to the sanitary sewer system. This plan shall include the following as appropriate: (a) An implementation plan and schedule for a public education outreach program that promotes proper disposal of FOG; (b) A plan and schedule for the disposal of FOG generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of FOG generated within a sanitary sewer system service area; (c) The legal authority to prohibit discharges to the system and identify measures to prevent SSOs and blockages caused by FOG; (d) Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, BMP requirements, record keeping and reporting requirements; (e) Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the FOG ordinance; (f) An identification of sanitary sewer system sections subject to FOG blockages and establishment of a cleaning maintenance schedule for each section; and (g) Development and implementation of source control measures for all sources of FOG discharged to the sanitary sewer system for each section identified in (f) above. (viii) System Evaluation and Capacity Assurance Plan: The Enrollee shall prepare and implement a capital improvement plan (CIP) that will provide hydraulic capacity of key sanitary sewer system elements for dry weather peak flow conditions, as well as the appropriate design storm or wet weather event. At a minimum, the plan must include: (a) Evaluation: Actions needed to evaluate those portions of the sanitary sewer system that are experiencing or contributing to an SSO discharge caused by hydraulic deficiency. The evaluation must provide estimates of peak flows (including flows from SSOs State Water Resources Control Board Order No. 2006-0003-DWQ Page 14 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 that escape from the system) associated with conditions similar to those causing overflow events, estimates of the capacity of key system components, hydraulic deficiencies (including components of the system with limiting capacity) and the major sources that contribute to the peak flows associated with overflow events; (b) Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation identified in (a) above to establish appropriate design criteria; and (c) Capacity Enhancement Measures: The steps needed to establish a short- and long-term CIP to address identified hydraulic deficiencies, including prioritization, alternatives analysis, and schedules. The CIP may include increases in pipe size, 1/1 reduction programs, increases and redundancy in pumping capacity, and storage facilities. The CIP shall include an implementation schedule and shall identify sources of funding. (d) Schedule: The Enrollee shall develop a schedule of completion dates for all portions of the capital improvement program developed in (a)-(c) above. This schedule shall be reviewed and updated consistent with the SSMP review and update requirements as described in Section D. 14. (ix) Monitoring, Measurement, and Program Modifications: The Enrollee shall: (a) Maintain relevant information that can be used to establish and prioritize appropriate SSMP activities; (b) Monitor the implementation and, where appropriate, measure the effectiveness of each element of the SSMP; (c) Assess the success of the preventative maintenance program; (d) Update program elements, as appropriate, based on monitoring or performance evaluations; and (e) Identify and illustrate SSO trends, including: frequency, location, and volume. (x) SSMP Program Audits - As part of the SSMP, the Enrollee shall conduct periodic internal audits, appropriate to the size of the system and the number of SSOs. At a minimum, these audits must occur every two years and a report must be prepared and kept on file. This audit shall focus on evaluating the effectiveness of the SSMP and the State Water Resources Control Board Order No. 2006-0003-DWQ Page 15 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 Enrollee's compliance with the SSMP requirements identified in this subsection (D.13), including identification of any deficiencies in the SSMP and steps to correct them. (xi) Communication Program — The Enrollee shall communicate on a regular basis with the public on the development, implementation, and performance of its SSMP. The communication system shall provide the public the opportunity to provide input to the Enrollee as the program is developed and implemented. The Enrollee shall also create a plan of communication with systems that are tributary and/or satellite to the Enrollee's sanitary sewer system. 14.Both the SSMP and the Enrollee's program to implement the SSMP must be certified by the Enrollee to be in compliance with the requirements set forth above and must be presented to the Enrollee's governing board for approval at a public meeting.

Over 85 percent of historic wetland and riparian acreage in California has been lost according to published research estimates. Remaining resources continue to be vulnerable to future impacts from projected population growth, land development, sea level rise, and climate change in California. 2. Although physically occupying only a small percentage of California watersheds, wetlands and riparian areas provide valuable water quality functions such as flood control, pollutant filtration, water supply and replenishment, recreation, and habitat for a wide variety of plants and animals. Wetlands and riparian areas act to promote the health and existence of other vital natural resources, and provide significant economic benefits to California. 3. The value of wetlands and riparian areas has been recognized in California through the enactment of the California Wetlands Conservation Policy that sets a goal to "ensure no overall net loss and achieve a long-term net gain in the quantity, quality, and permanence of wetlands acreage and values in California in a manner that fosters creativity, stewardship, and respect for private property" (Executive Order W-59-93). 4. The State has relied primarily on requirements of the Federal Water Pollution Control Act (33 U.S.C. § 1251 et seq.) (Clean Water Act) to protect wetlands and riparian areas for water quality goals. 5. Recent U.S. Supreme Court rulings (Solid Waste Agency of Northern Cook County v. U.S. Army Corps of Engineers, 2001 and Rapanos v. United States, 2006) have reduced the jurisdiction of the Clean Water Act over wetland and riparian areas by limiting the definition of "waters of the United States." These decisions necessitate the use of California's independent authorities under the Porter-Cologne Water Quality Control Act (Wat. Code, § 13000 et seq.) to protect these vital resources. 6. In 2003, the State Water Resources Control Board (State Water Board) issued a report to the Legislature titled, Regulatory Steps Needed to Protect and Conserve Wetlands Not Subject to the Clean Water Act (Supplemental Report of the 2002 Budget Act Item 3940-001-0001). This report reviewed the critical role that wetlands and riparian areas have in protecting the beneficial uses of waters throughout the State. Consistent with the State Water Board and Regional Water Quality Control Boards' (Regional Water Boards) (collectively California Water Boards) 2001 Watershed Management Initiative, this report further recognizes that a watershed-level approach is needed to protect wetlands and riparian areas and their associated water quality functions. 7. In 2004, State Water Board staff initiated a Workplan upon the California Environmental Protection Agency's request (Workplan: Filling the Gaps in Wetland Protection) to address the waters of the State that are no longer protected under the Clean Water Act. This Workplan specified the need to adopt a State wetland definition to "provide a standard metric to help determine compensatory mitigation requirements and compliance with [the] 'no net loss' policy [Executive Order W-59-93]." In addition, the Workplan included developing a statewide policy for wetland protection "at least as protective as the federal requirements." To immediately address part of"the gap," the State Water Board adopted general waste discharge requirements for minor discharges to non-federal waters (Water Quality Order 2004-0004 May 4, 2004). 8. California continues to lose "functional wetlands" at an increasing rate despite the efforts of the State's 401 Water Quality Certification Program. This fact is documented in a State Water Board research study contracted with UCLA titled An Evaluation of Compensatory Mitigation Projects Permitted Under Clean Water Act Section 401 by The California State Water Resources Control Board, 1991-2002. The current implementation of the 401 Water Quality Certification Program does not adequately protect functional wetlands. Unfortunately, compliance with regulatory requirements has not resulted in resource protection. Clearly, there is a need for a strong statewide policy that provides both guidance on the protection and restoration of wetlands, as well as assessing and measuring net change in wetland functions. . The purpose of the proposed Policy is to ensure no further net loss and ultimate long-term gain in the quantity and quality of"functional" wetlands and riparian areas within the State. Successful implementation of the proposed Policy will be assessed via measurable environmental outcomes. 9. In 2007, State Water Board staff completed public scoping meetings on wetland and riparian area policy alternatives and considered comments received in accordance with the California Environmental Quality Act. THEREFORE BE IT RESOLVED THAT: 1. The State Water Board recognizes the beneficial services of wetlands and riparian areas for people and wildlife in protecting and improving water quality, providing fish and wildlife habitat including unique plant communities (i.e., wetland and riparian vegetation), storing floodwaters, maintaining surface water flows in dry periods, and other valuable functions. California has a rich ecological diversity, therefore, the State Water Board further recognizes that watershed focused planning is the most effective strategy for maintaining and enhancing these functions. 2. The State Water Board will take action to ensure the protection of the vital beneficial services provided by wetlands and riparian areas through the development of a statewide policy to protect wetlands and riparian areas (Policy) that is watershed-based. 3. The Development Team, as defined below, will examine the environmental issues, evaluate the relevant alternatives, and make recommendations regarding the Policy. To ensure a comprehensive scope, the staff is directed to consider additional alternatives and recommendations other than those outlined in the 2004 Workplan. 4. In recognition that successful Policy implementation will require a supporting level of internal program infrastructure, major policy areas should be addressed in a step-wise fashion and implemented in phases to allow for commensurate program development. The Policy shall -2- support efforts to collect wetland data to monitor progress towards statewide wetland protection and to evaluate the level of program resources needed, including staffing, to undertake the next phases. 5. (a) The State Water Board staff is directed to develop the Policy using a collaborative process that involves the Regional Water Boards and bring that Policy to the State Water Board for consideration. A California Water Board development team (Development Team) will be formed for the Policy. The Development Team will consider and utilize relevant plans, policies, and technical documents already adopted or being developed by the Regional Water Boards, including the Stream and Wetland Systems Protection Policy Basin Plan Amendment being prepared by Regions 1 and 2. (b) The Development Team will coordinate with other State and federal agencies and interested stakeholders to ensure a high degree of public involvement and agency coordination throughout the Policy development process. (c) A charter will be developed by the Development Team defining the Development Team's purpose, responsibilities, goals and objectives, operating procedures, and timelines. The charter will identify the relationship of the Development Team to the water boards, other public agencies, and stakeholders. In July 2008, the Development Team will report back to the State Water Board on the proposed charter, before adoption by the Development Team. (d) The State Water Board will review the Development Team's progress in July 2008, and periodically thereafter to provide oversight guidance as needed. (e) The Policy, as well as the work of the Development Team, will inform and shape proposed Regional Basin Plan amendments. At a minimum for the proposed Regional Basin Plan amendments, this would include a review following the completion of the peer review process, and also a review within the public comment period prior to adoption hearings by the Regional Water Boards. 6. The Development Team will develop the Policy in three phases: Phase 1 — establish a Policy to protect wetlands from dredge and fill activities. The Development Team is directed to develop and bring forward for State Water Board consideration: (a) a wetland definition that would reliably define the diverse array of California wetlands based on the United States Army Corps of Engineers' wetland delineation methods to the extent feasible, (b) a wetland regulatory mechanism based on the 404 (b)(1) guidelines (40 C.F.R. parts 230-233) that includes a watershed focus, and (c) an assessment method for collecting wetland data to monitor progress toward wetland protection and to evaluate program development. Phase 2 — expand the scope of the Policy to protect wetlands from all other activities impacting water quality. The Development Team is directed to develop and bring forward for State Water Board consideration: (a) new beneficial use definitions, (b)water quality objectives, and (c) a program of implementation to achieve the water quality objectives, as necessary, to protect wetland-related functions. -3- Phase 3 — extend the Policy's protection to riparian areas. The Development Team is directed to develop, and bring forward for State Water Board consideration: (a) new beneficial use definitions, (b) water quality objectives, and (c) a program of implementation to achieve the water quality objectives, as necessary, to protect riparian area-related functions. 7. The Development Team will begin Phase 1 immediately with a target completion date of mid- 2009. Work on Phases 2 and 3 will proceed in parallel or in sequence as appropriate and will follow in subsequent years. Phase 1 work products will include: a. An overarching policy statement establishing the intent of the California Water Boards to protect all waters of the State using a watershed approach in coordination with the Regional Water Boards; other local, State, and federal agencies; and local watershed and stakeholder groups and forums; b. A wetland definition that would reliably define the diverse array of California wetlands based on the United States Army Corps of Engineers' wetland delineation methods to the extent feasible; C. A framework for protecting water quality and beneficial uses that relies on sequential avoidance, minimization, and mitigation of impacts; and, d. Guidance on tracking wetland condition and function to monitor wetland protection and other required data to evaluate necessary program development resources. 8. At all phases, the Policy is intended to complement and support Region-specific plans and policies to protect the functionality of wetlands and riparian areas and should recognize the Regional Water Boards' essential role in implementing and informing statewide policy.

WQ 2013-0058-EXEC AMENDING MONITORING AND REPORTING PROGRAM FOR STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS FOR SANITARY SEWER SYSTEMS The State of California, Water Resources Control Board (hereafter State Water Board) finds: 1. The State Water Board is authorized to prescribe statewide general Waste Discharge Requirements (WDRs)for categories of discharges that involve. the same or similar operations and the same or similar types of waste pursuant to Water Code section 13263(i). 2. Water Code section 13193 et seq. requires the Regional Water Quality Control Boards (Regional Water Boards) and the State Water Board (collectively, the Water Boards)to gather Sanitary Sewer Overflow (SSO) information and make this information available to the public, including but not limited to, SSO cause, estimated volume, location, date, time, duration, whether or not the SSO reached or may have reached waters of the state, response and corrective action taken, and an enrollee's contact information for each SSO event. An enrollee is defined as the public entity having legal authority over the operation and maintenance of, or capital improvements to, a sanitary sewer system greater than one mile in length. 3. Water Code section 13271, et seq. requires notification to the California Office of Emergency Services (Cal OES), formerly the California Emergency Management Agency, for certain unauthorized discharges, including SSOs. 4, On May 2, 2006, the State Water Board adopted Order 2006-0003-DWQ, "Statewide Waste Discharge Requirements for Sanitary Sewer Systems"' (hereafter SSS WDRs) to comply with Water Code section 13193 and to establish the framework for the statewide SSO Reduction Program. 5. Subsection G.2 of the SSS WDRs and the Monitoring and Reporting Program (MRP) provide that the Executive Director may modify the terms of the MRP at any time. 6. On February 20, 2008, the State Water Board Executive Director adopted a revised MRP for the SSS WDRs to rectify early notification deficiencies and ensure that first responders are notified in a timely manner of SSOs discharged into waters of the state. 7. When notified of an SSO that reaches a drainage channel or surface water of the state, Cal OES, pursuant to Water Code section 13271(a)(3), forwards the SSO notification information to local government agencies and first responders including local public health officials and the applicable Regional Water Board. Receipt of notifications for a single SSO event from both the SSO reporter ' Available for download at: http:/Iwww.waterboards.ca.gov/board decisions/adopted orders/water quality/2006/wcio/wgo2006 0003.pdf 2 Cal OES Hazardous Materials Spill Reports available Online at: http://w3.calema.ca.gov/operational/malhaz.nsf/$defaultview and http://w3.calema.ca.gov/operational/malhaz.nsf Monitoring and Reporting Program Order No. WQ 2013-0058-EXEC Page 2 of 2 Statewide Waste Discharge Requirements for Sanitary Sewer Systems and Cal OES is duplicative. To address this, the SSO notification requirements added by the February 20, 2008 MRP revision are being removed in this MRP revision. 8. In the February 28, 2008 Memorandum of Agreement between the State Water Board and the California Water and Environment Association (CWEA), the State Water Board committed to re- designing the CIWQS3 Online SSO Database to allow"event" based SSO reporting versus the original "location" based reporting. Revisions to this MRP and accompanying changes to the CIWQS Online SSO Database will implement this change by allowing for multiple SSO appearance points to be associated with each SSO event caused by a single asset failure, 9. Based on stakeholder input and Water Board staff experience implementing the SSO Reduction Program, SSO categories have been revised in this MRP. In the prior version of the MRP, SSOs have been categorized as Category 1 or Category 2. This MRP implements changes to SSO categories by adding a Category 3 SSO type. This change will improve data management to further assist Water Board staff with evaluation of high threat and low threat SSOs by placing them in unique categories (Le., Category 1 and Category 3, respectively). This change will also assist enrollees in identifying SSOs that require Cal OES notification. 10. Based on over six years of implementation of the SSS WDRs, the State Water Board concludes that the February 20, 2008 MRP must be updated to better advance the SSO Reduction Program4 objectives, assess compliance, and enforce the requirements of the SSS WDRs. IT IS HEREBY ORDERED THAT: Pursuant to the authority delegated by Water Code section 13267(f), Resolution 2002-0104, and Order 2006-0003-DWQ, the MRP for the SSS WDRs (Order 2006-0003-DWQ) is hereby amended as shown in Attachment A and shall be effective on September 9, 2013.

WQ 2013-0058-EXEC AMENDING MONITORING AND REPORTING PROGRAM FOR STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS FOR SANITARY SEWER SYSTEMS This Monitoring and Reporting Program (MRP) establishes monitoring, record keeping, reporting and public notification requirements for Order 2006-0003-DWQ, "Statewide General Waste Discharge Requirements for Sanitary Sewer Systems" (SSS WDRs). This MRP shall be effective from September 9, 2013 until it is rescinded. The Executive Director may make revisions to this MRP at any time. These revisions may include a reduction or increase in the monitoring and reporting requirements. All site specific records and data developed pursuant to the SSS WDRs and this MRP shall be complete, accurate, and justified by evidence maintained by the enrollee. Failure to comply with this MRP may subject an enrollee to civil liabilities of up to $5,000 a day per violation pursuant to Water Code section 13350; up to $1,000 a day per violation pursuant to Water Code section 13268; or referral to the Attorney General for judicial civil enforcement. The State Water Resources Control Board (State Water Board) reserves the right to take any further enforcement action authorized by law. A.

Public Health Considerations Waterborne disease outbreaks attributed to the entry of sewage-contaminated groundwater into the distribution systems of public water supplies continues to be an issue in the united states. A community with its buried water mains in close proximity to sanitary sewers is vulnerable to waterborne disease outbreaks. Sanitary sewers frequently leak and saturate the surrounding soil with sewage.This is caused primarily by structural failure of the sewer line, improperly constructed joints, and subsidence or upheaval of the soil encasing the conduit. A serious public health hazard exists when the water mains are depressurized and no pressure or negative pressures occur. The hazard is further compounded when, in the course of installing or repairing a water main,existing sewer lines are broken.Sewage spills into the excavation and, hence, enters into the water main itself. Additionally, if a water main fails in close proximity to a sewer line, the resultant failure may disturb the bedding of the sewer line and cause it to fail. In the event of an earthquake or man-made disaster,simultaneous failure of both conduits often occurs. The water supplier is responsible for the quality of the water delivered to consumers and must take all practical steps to minimize the hazard of sewage contamination to the public water supply. Protection of the quality of the water in the public water system is best achieved by the barrier provided by the physical separation of the water mains and sewer lines. This document sets forth the construction criteria for the installation of water mains and sewer lines to prevent contamination of the public water supplies from nearby sanitary sewers. B. Basic Separation Standards The"California Waterworks Standards"sets forth the minimum separation requirements for water mains and sewer lines. These standards, contained in Section 64630,Title 22,California Administrative Code,specify: a. (1) Parallel construction:the horizontal distance between pressure water mains and sewer lines shall be a minimum of 10 feet. (2) Perpendicular construction(crossing): pressure water mains shall be at least one foot above sanitary sewer lines where these lines must cross. b. Separation distances specified in(c)shall be measured from the edge of the nearest facility. C. (2) Common trench:water mains and sewer lines must not be installed in the same trench. When water mains and sanitary sewers are not adequately separated, the potential for contamination of the water supply increases. Therefore, when adequate physical separation cannot be attained, an increase in the factor of safety should be provided by increasing the structural integrity of both the pipe materials and joints. C. Exceptions to Basic Separation Standards Local conditions, such as available space, limited slope, existing structures, etc., may create a situation where there is no alternative but to install water mains or sewer lines at a distance less than that required by the Basic Separation Standards. In such cases, alternative construction criteria as specified in Section E should be followed,subject to the special provisions in Section D. Water mains and sewers of 24 inches diameter or greater may create special hazards because of the large volumes of flow. Therefore, installations of water mains and sewer lines 24 inches in diameter or larger should be reviewed and approved by the health agency prior to construction. CIO`� O� REVISIONS BY APP DATE Y WATER-SEWER -� SEPARATION SCALE: NTS SHEET NO: 1 OF 2 0 Q STANDARD CURRENT AS OF: APRIL 2020 205 D.Special Provisions 1. The basic separation standards are applicable under normal conditions for sewage collection lines and water distribution mains. more stringent requirements may be necessary if conditions such as high groundwater exist. 2. Sewer lines shall not be installed within 26 feet horizontally of a low head(5 psi or less pressure)water main. 3. New water mains and sewers shall be pressure tested and videoed where the conduits are located 10 feet apart or less. 4. In the installation of water mains or sewer lines, measures should be taken to prevent or minimize disturbances of the existing line. Disturbance of the supporting base of this line could eventually result in failure of this existing pipeline. 5. Special consideration shall be given to the selection of pipe materials if corrosive conditions are likely to exist. The conditions may be due to soil type and/or the nature of fluid conveyed in the conduit,such as a septic sewage which produces corrosive hydrogen sulfide. 6. Sewer force mains A. Sewer force mains shall not be installed within 10 feet(horizontally)of a water main. B. When a sewer force main must cross a water line,the crossing should be as close as practical to perpendicular.The sewer force main should be at least 12 inches below the water line. C. When a new sewer force main crosses under an existing water main, all portions of the sewer force main within 10 feet (horizontally)of the water main shall be enclosed in a continuous sleeve. D. When a new water main crosses over an existing sewer force main,the water main shall be constructed of pipe materials with a minimum rated working pressure of 200 psi or equivalent pressure rating. E. Alternative Criteria for Construction The construction criteria for sewer lines or water mains where the Basic Separation Standards cannot be attained are shown in Figures 1 and 2, Engineering Standard#205,Sheets 3 and 4.There are two situations encountered: Case 1 -New sewer line-new or existing water main. Case 2-New water main-existing sewer line. For Case 1,The alternative construction criteria apply to the sewer line. For Case 2,The alternative construction may apply to either or both the water main and sewer line. The construction criteria should apply to the house laterals that cross above a pressure water main but not to those house laterals that cross below a pressure water main.

Wastewater Disposal Sanitary sewer lines and appurtenances within County-operated special districts shall be constructed in accordance with the details shown on plans and specifications approved by the Department. Where a sewer system in the unincorporated area of the County is to be operated and/or maintained by any public agency other than the County, or local purveyor regulated by the State of California, the plans and specifications and construction must be approved by both the Department and by that entity. In the event of any discrepancy or conflict between these Public Improvement Standards and the requirements of said wastewater service purveyor,that entity's requirements shall take precedence. 7.1 Design Standards 7.1.1 Quantity of Flow A. Average Flow Rate. An average flow of 100-gallons per person per day shall be used for design purposes, with the peak flow double the average flow. Pipes shall be sized to handle peak flows with the pipe flowing half full for sewers up to 15-inches in diameter. Larger sanitary sewers shall be designed to flow 3/4 full. B. Number of Persons Served. Accurate population estimates will be required to determine the quantity of flow. Multiply the future population by the average per capita wastewater flow, given in (A) above. Estimates of the number of visitors associated with recreational uses, which experience high seasonal fluctuation, can be converted to equivalent full-time residents by multiplying the number of visitors by the appropriate multiplier below: Day-use visitor 0.1 - 0.2 Seasonal visitor 0.5 - 0.8 The number of persons shall be determined for a 50-year period, which is the length of time that the capacity of the sanitary sewer will be adequate. Day-use visitors are those who do not stay overnight (for example, boating or picnicking), and seasonal visitors are those who stay for short multi-day stays during peak recreational seasons (for example, camping or cabins). 7.1.2 Collection System A. Minimum Velocity. Sanitary sewer grades shall be designed to provide a minimum velocity of 2 fps when flowing at peak discharge as determined in section 7.1.1 A, above. The minimum velocity requirement is necessaryto prevent the deposition of solids. The following table indicates the slopes which will provide that velocity, and these shall be used as the minimum standard for design.

Sewer Lines Within Easements. Where sewer lines are located within easements, the easements shall be offered for dedication to the public.The minimum width of any easement for sanitary sewer purposes shall be 10-feet. In special cases of terrain, depth of sewer line, etc., the required easement width shall be increased. All easements shall include right of ingress and egress over adjoining property for maintenance, replacement and operation. G. Alignment. Sewerage systems shall be designed so as to have a minimum of curvature, both horizontal and vertical. Whenever possible, sewer lines shall be laid out in a straight line between structures. Curved sewer lines will be allowed only under the following conditions: • All curve data shall be shown on the plans. • Minimum radius of curvature shall be as recommended by the pipe manufacturer and approved by the Department. Wastewater Disposal: 7-2 County of San Luis Obispo- 2019 Public Improvement Standards • No deflections shall be made at the pipe joints. H. Depth.

Sewer mains shall be placed with 48-inch minimum cover and shall be located deeper than any nearby potable or reclaimed water mains. I. Size. The normal minimum sewer main size shall be 8-inches inside diameter. 7.1.3 Areas of Conflict between Sewer and Water Lines In the interest of public health and to minimize the possibility of contamination of the public water supply, the construction requirements included in Standard Drawing Series U-3 shall be met at any time that the separation between water and sewer lines is less than the basic separation standards contained in State regulations. These requirements apply to construction of a water main, sewer main, sewer lateral, or any other type construction causing the separation to be less than that indicated. All special construction required herein is to be discussed thoroughly with the Department, and the Department of Public Health/Environmental Health Services, prior to starting any work and is subject to Department approval. 7.1.4 Areas of Conflict between Sewer and Storm Drain Lines In the interest of public health and to minimize the possibility of contamination of the drainage system and water course, at least four feet of clearance shall be maintained between parallel sewer lines and storm drains (and structures). Where either pipe is protected by concrete encasement, the separation shall be measured to the outside of the concrete encasement. Where maintaining the four feet of separation is not practical, special designs may be approved by the Department(via a design exception)to minimize the potential for cross contamination. 7.2 Construction Specifications 7.2.1 Materials All material that is to become a permanent part of any sanitary sewer or appurtenant structure, shall conform to the requirements for the particular material as set forth in these specifications.

In addition, a string line shall be used in the bottom of the trench to ensure proper alignment and grade. 2. Pipe shall be laid continuously upgrade, with the bell of the pipe forward. Each length of pipe shall be laid on a firm bed and shall have a true bearing for the entire length. No wedging or blocking up of the pipe will be permitted. 3. Both bell and spigot shall be clean before the joint is made, and care shall be taken that nothing but the joint-making material enters the joints. 4. When, for any reason, pipe laying is discontinued for an hour or more, the open end of each line shall be closed with a close-fitting stopper. 5. The Contractor's attention is called to the required use of short lengths of sewer pipe to provide curves, flexibility, and prevent cracking or shearing failures. The use of short lengths of pipe is particularly required for, but not necessarily limited to, these locations: (1) inlets and outlets to all manholes; and (2)vertical and horizontal curvilinear sewers. E. Pipe to be Placed by Boring or Jacking. This work consists of placing cast iron pipe or other pipe of approved material, usually in a conductor pipe, under a paved roadway or railroad to a true line and grade as shown on the plans, by means of boring or jacking operations. The equipment and method of operation shall be approved by the Department before proceeding with the work, and shall meet the following requirements: 1. The excavation for the boring operation shall be kept to a minimum but shall be of sufficient dimensions to satisfactorily complete the work. If so required, bracing and shoring shall be provided to adequately protect the workers and the roadway or railroad. 2. The conductor pipe shall be placed closely behind and in conjunction with the boring operation. The bored hole shall be not more than 2-inches in diameter larger than the conductor pipe. Guide rails shall be accurately set to line and grade so as to achieve close adherence to the line and grade shown on the plans. 3. The pipe to be placed inside the conductor pipe shall have non-rigid joints and shall be installed by the use of suitable centering devices. Sand, or other approved material, shall then be pumped into the conductor pipe to completely fill the annular space around the pipe for its full length. Wastewater Disposal: 7-6 County of San Luis Obispo- 2019 Public Improvement Standards F. Trench Bedding and Backfill. Trench bedding and backfill shall be placed in the same manner as described for water mains in Chapter 6, including use of tracer wire and warning tape, except as follows: The non-detectable warning tape shall be 3-inch wide polyethylene,APWA uniform color-coded green, permanently printed "CAUTION BURIED SEWER LINE BELOW." G. Manholes. Manholes shall be watertight structures constructed by placing precast concrete sections on a poured concrete base. Poured-in-place manholes shall not be used unless specifically called for in the Special Provisions. The following requirements shall apply: 1. Temporary covers of 3/8-inch steel plate of sufficient size to adequately cover the opening shall be placed on the cone until the pavement is completed. Suitable locating ribs shall be welded to the underside of the cover to hold it in place during the grading and paving operations. 2. When adjusting an existing manhole to grade and the total depth of the throat from the top of the frame to the bottom of the throat exceeds 24-inches, the upper portion of the manhole shall be removed to the first full-size manhole section. The upper portion shall then be reconstructed as outlined above. 3. Manholes shall be tested for water tight integrity either jointly with testing of sewer line or as separate units, in accordance with the Testing specifications, in section 7.2.4 below. The allowable leakage for one manhole shall not exceed one (1)gallon during a two-hour test period. H. Connection to Existing Manholes. Connections to existing manholes shall conform to the requirements of Standard Drawing S-1 and shall be made by coring a hole in the wall of the manhole, inserting the end of the pipe through the opening, flush with the inside wall, and packing the opening around the pipe with a non-shrink grout,thoroughly compacted to form a watertight connection. The grout shall be troweled smooth and flush with the interior surface of the manhole. A manhole adapter or water stop shall be placed on the pipe prior to placement in hole, and the pipe shall be installed as specified by the manufacturer. Channelizing of the flow through the manhole shall conform to the details shown on the Standard Drawings for new manholes. The Contractor shall notify the Department, 24 hours in advance, before any connection is made to existing structures. The Contractor shall schedule the work so that interruption of flow is held to a minimum. I. House Service Laterals. House service laterals shall be constructed as shown on the Standard Drawing S-3 and S-3a, and shall conform to the following requirements: 1. If it becomes necessary to locate a house service lateral less than 100-feet from a well, it shall be constructed of a suitable material approved by the Department and the Public Health Department/ Environmental Health Services. Approved construction materials for sewer lines in critical zones are listed in Section 7.1.3 above. 2. Whenever house service laterals are to be installed as part of the contract for the construction of the lateral sewer, the use of wye or tee saddles will not be permitted. 3. That portion of any house service lateral to be placed under an existing curb and gutter and/or sidewalk shall be done by tunneling. Cutting of the existing curb and gutter and/or sidewalk will not be permitted. Wastewater Disposal: 7-7 County of San Luis Obispo- 2019 Public Improvement Standards 4. All house service laterals shall be considered as part of the lateral sewers for purposes of the hydrostatic test as set forth in Testing, below. 5. The location of house service laterals shall be permanently indicated by embedding the letter"S" in the curb directly above the line. In new subdivisions when the house service laterals are installed, before the curb is constructed, it shall be the sewer contractor's responsibility to place the "S" in the curb after it is poured. When house service laterals are constructed in existing easements or streets where curbing does not exist, a 2-inch by 2-inch by 36-inch maximum (2"x2"x36") construction grade redwood stake shall be driven in the ground to within two inches of the surface, directly above the service line at the property line and an "S" stamped in the top. Every house service lateral shall be so marked before final acceptance will be given of any job. 7.2.4 Testing Prior to final approval, all sewer lines shall be cleaned and tested for leakage by standard hydrostatic or low-pressure air test,for deflection by mandrel test, and for standing water/other debris by TV inspection. All cleaning and testing shall take place after all utilities are installed, and up to, but not including the final paving is completed. Any damage to the system during final paving and cleanup shall be corrected prior to final approval. A. Cleaning. Prior to acceptance of any sewer line by the Department, the sewer line shall be cleaned with a Wayne-type sewer cleaning ball under hydrostatic pressure. Any stoppage, dirt or foreign matter shall be removed from the lines. All materials and debris removed shall be collected and vacuumed out of the system at a manhole selected by the Department, and no debris shall be washed or otherwise deposited into the system. B. Hydrostatic Test Procedure. A section of sewer line shall be prepared for testing by plugging the upper side of the downstream manhole and all openings in the upstream manhole except the downstream opening. Where grades are slight,two or more sections between manholes may be tested at once. Where grades are steep, and excessive test heads would result by testing from one manhole to another, test tees the full size of the main shall be installed at intermediate points so the maximum head on any section under test will not exceed 12-feet. The following sequence shall be used: 1. The section of sewer line prepared as above shall be tested by filling with water to an elevation 5-feet above the top of pipe at the upstream end of the test section, or 5-feet above the existing ground water elevation, whichever is greater. The water should be introduced into the test section four hours in advance of the official test period to allow the pipe and joint material to become saturated. The pipe shall then be refilled to the original water level. 2. At the beginning of the test, the elevation of the water in the upper manhole shall be carefully measured from a point on the manhole rim. After a period of four hours, or less with the approval of the Department, the water elevation shall be measured from the same point on the manhole rim and the loss of water during the test period calculated. If this calculation is difficult, enough water shall be measured into the upper manhole to Wastewater Disposal: 7-8 County of San Luis Obispo- 2019 Public Improvement Standards restore the water to the level existing at the beginning of the test, and the amount added taken as the total leakage. 3. Should an initial test show excess leakage in a section of line, it is permissible to draw the water off and test the manholes that contained water. This test shall be made by plugging all the openings in the manholes and filling with water to the same elevation as existed during the test. The leakage from the manhole may be deducted from the total leakage of the test section in arriving at the test leakage. After the testing is complete, the manhole shall be waterproofed by grouting. Other approved waterproofing methods may be used if satisfactory to the Department. 4. The allowable leakage in the test section shall not exceed 500-gallons per mile, per 24- hours per inch diameter of pipe tested at the 5-foot test head. 5. If it is necessary or desirable to increase the test head above 5-feet,the allowable leakage will be increased at the rate of 80-gallons for each foot of increase in head. 6. Test sections showing leakage in excess of that allowed shall be repaired or reconstructed as necessary to reduce the leakage to that specified above, and the line retested, after a minimum period of 24-hours during which no additional water shall be introduced into the line. C. Air Test Procedure. Each section of sanitary sewer between two successive manholes shall be tested by plugging all pipe outlets with suitable test plugs. Air shall be slowly added until the internal pressure is raised to 4-pounds per square inch gauge (psig). The compressor used to add air to the pipe shall have a blow-off valve set at 5 psig to assure that at no time the internal pressure exceeds 5 psig. The internal pressure of 4 psig shall be maintained for at least two minutes to allow the air temperature to stabilize, after which the air supply shall be disconnected and the pressure allowed to decrease to 3.5 psig. The time in minutes that is required for the internal pressure to drop from 3.5 psig to 2.5 psig shall be measured and the results compared with the values tabulated below. Air Test Procedure Pipe Diameter Minimum Distance (inches) Test Time (minutes) Between Manholes (feet) 8 4 340 10 5 260 12 6 230 15 7 170 18 9 150 21 10 120 24 11 110 27 13 100 30 14 90 33 16 80 36 17 70 Wastewater Disposal: 7-9 County of San Luis Obispo- 2019 Public Improvement Standards Pipe Diameter Test Time (minutes) Minimum Distance (inches) Between Manholes (feet) 39 18 60 42 19 50 The above tabulated values shall be used for the respective diameter pipes except where the distance between successive manholes is less than the above tabulated values, or the pipe diameter is less than 8-inches, in which case the following formula will be used to determine the test time: (1) T= 0.000183 dz L T =test time (minutes) d = inside diameter of pipe (inches) L = distance between successive manholes (feet) If the pressure drop from 3.5 psig to 2.5 psig occurs in less time than the above tabulated or calculated values, the pipe shall be repaired and, if necessary, replaced and re-laid at the Contractor's expense until the joints and pipe shall hold satisfactorily under this test. The Contractor shall furnish all labor, air test equipment, and all other materials for making the required air test at his or her own expense. After the sewer lines have been properly backfilled to a depth where additional backfilling will not disturb the position of the pipe, all or any sections that the Department may select may be tested. In no case shall the required minimum backfill be less than 4-feet above the top of the pipe before subjecting the line to the test. The Contractor shall supply all equipment, material and perform all tests as required prior to final approval. D. Deflection Test. Following the placement and densification of backfill, and prior to the placing of permanent pavement, all pipe shall be cleaned and then mandrel measured for obstructions (deflections, joint offsets, and lateral pipe intrusions). A rigid mandrel, with a circular cross-section having a diameter of at least 95% of the specified average inside diameter, shall be pulled through the pipe by hand. The minimum length of the circular portion of the mandrel shall be equal to the nominal diameter of the pipe. Unless otherwise permitted by the Department, any over-deflected pipe shall be uncovered and, if not damaged, reinstalled. Damaged pipe lengths shall not be reinstalled but shall be removed from the work site. Any pipe subjected to any method or process other than removal, which attempts - even successfully-to reduce or cure any deflection, shall be uncovered, removed from the work site, and replaced with new pipe. The mandrel used shall be: 1. effective length not less than its nominal diameter 2. fabricated of steel 3. fitted with pulling rings at each end 4. furnished in a suitable carrying case labeled with the same data as stamped or engraved on the mandrel Wastewater Disposal: 7-10 County of San Luis Obispo- 2019 Public Improvement Standards 5. rigid, nonadjustable, with an odd number of legs (9 legs minimum) 6. stamped or engraved, on some segment other than a runner, indicating the pipe material specification, nominal size, and mandrel OD E. TV Inspection. For wastewater collection systems operated by the County, a TV inspection and report shall be required prior to acceptance. F. Force Mains. Each section of pipe to be tested shall be slowly filled with water and all air expelled from the pipe. After the pipe has been filled, it shall be allowed to set for a period of not less than 24-hours. The pipe shall then be refilled to the original water level and subjected to a pressure of not less than 150-pounds per square inch, or the service pressure plus 50-pounds, whichever is greater, for a period of 2-hours. All exposed joints, bends, angles, and fittings shall be closely examined during the test. Any part of the line which proves to be defective shall be replaced and the line retested. The maximum allowable leakage shall not exceed 100-gallons per mile, per 24-hours per inch of nominal diameter. 7.2.5 Replacement of Road Surfaces A. Timing of Pavement Replacement. Paving replacement shall not proceed until the full requirements of Installation and Testing, above, have been met to the satisfaction of the Department, but in no less than ten (10) days after backfilling has been completed. B. Pavement Replacement Requirements. The replacement of all pavement and shoulder surfaces shall be in conformance with Section 3 of these Public Improvement Standards, as to materials and methods of construction.

G\OERP.doc City of Pismo Beach - Sewer System Management Plan OVERFLOW EMERGENCY RESPONSE PLAN 1.0 INTRODUCTION The City of Pismo Beach (City) is committed to the proper operation and management of their sanitary sewer collection system to minimize sanitary sewer overflows (SSOs).The City's Overflow Emergency Response Plan (OERP) summarizes the procedures that are used by City employees to respond, investigate, and report SSOs to the appropriate agencies.This plan is intended to serve as an update to the City's OERP implemented in 2007 to incorporate the requirements of Order No. WQ 2013-0058-EXEC. 1.1 Regulatory Requirement Order No. 2006-0003 specifies that a Sewer System Management Plan (SSMP) must include an Overflow Emergency Response Program. SSO response and reporting requirements were revised with the July 30, 2013 amendment to State Water Board's GWDRs for sanitary sewer systems. At a minimum,this plan must include the following: a. Proper notification procedures so that the primary responders and regulatory agencies are informed of all sanitary sewer overflows (SSOs) in a timely manner; b. A program to ensure an appropriate response to all overflows; C. Procedures to ensure prompt notification to appropriate regulatory agencies and other potentially affected entities (e.g. health agencies, Regional Water Boards, water suppliers, etc.) of all SSOs that potentially affect public health or reach the waters of the State in accordance with the monitoring reporting program (MRP), the California Water Code, other State Law, and other applicable Regional Water Board waste discharge requirements (WDRs) or National Pollutant Discharge Elimination Program (NPDES) permit requirements.The SSMP should identify the officials who will receive immediate notification; d. Procedures to ensure that appropriate staff and contractor personnel are aware of and follow the Emergency Response Plan and are appropriately trained; e. Procedures to address emergency operations, such as traffic and crowd control and other necessary response activities; and f. A program to ensure that all reasonable steps are taken to contain and prevent discharge of untreated or partially treated wastewater to waters of the United States and to minimize or correct any adverse impact of the environment resulting from the SSOs, including such accelerated or additional monitoring as may be necessary to determine the nature and impact of the discharge. June 2020 1 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\Appendices\Appendix G\OERP.doc 1.2 Definition of a Sanitary Sewer Overflow An SSO included any overflow, spill, release discharge or diversion of untreated or partially treated wastewater from a sanitary sewer system.Temporary storage and conveyance facilities under City control (such as vaults,temporary piping, construction trenches, wet wells, impoundment,tanks, etc.) are considered to be part of the sanitary sewer system, and discharges to these temporary storage facilities are not considered to be SSOs.There are four categories of SSOs as established by the SWRCB's Order: • Category 1: Discharges of untreated or partially treated wastewater of any volume resulting from an enrollee's sanitary sewer system failure or flow condition that: a. Result in a discharge to a drainage channel and/or surface water; or b. Discharge to a Municipal Separate Storm Sewer System (MS4)that was not fully captured and returned to the sanitary sewer system.Any volume of wastewater not recovered from the municipal separate storm sewer system is considered to have reached surface water unless the storm drain system discharges to a dedicated storm water or groundwater infiltration basin (e.g., infiltration pit, percolation pond) C. Conduct water quality sampling within 48 hours after initial SSO notification for Category 1 SSO that exceed 50,000 gallons or greater to a surface water. (See Appendix B) Notification: Within two hours of becoming aware of any Category 1 SSO greater than or equal to 1,000 gallons discharged to a surface water or spilled in a location where it probably will be discharged to surface water notify the California office of Emergency Services (Cal OES) and obtain a notification number. Reporting: Submit draft report within three business days of becoming aware of the SSO and certify within 15 calendar days of the SSO and date. Technical Report: Submit within 45 calendar days after the end date of any Category 1 SSO in which 50,000 gallons or greater are spilled to surface waters. • Category 2: Discharges of untreated or partially treated wastewater of 1,000 gallons or greater resulting from an enrollee's sanitary sewer system failure or flow condition that do not reach surface water, a drainage channel, or a municipal separate storm sewer system unless the entire SSO discharged to the storm drain system is fully recovered and disposed of properly. Reporting: Submit draft report within three business days of becoming aware of the SSO and certify within 15 calendar days of the SSO and date. • Category 3: All other discharges of untreated or partially treated wastewater resulting from an enrollee's sanitary sewer system failure or flow condition. June 2020 2 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\Appendices\Appendix G\OERP.doc Reporting: Submit certified report within 30 calendar days of the end of the month in which SSO occurred. • Private Lateral Sewage Discharges: Discharges of untreated or partially treated wastewater resulting from blockages or other problems within a privately owned sewer lateral connected to the enrollee's sanitary sewer system or from other private sewer assets. As part of Order No. 2006-0003, all agencies that own or operate sanitary systems greater than one mile in length that collect and/or convey untreated or partially treated wastewater to a publicly owned treatment facility are required to report Category 1, 2 &3 SSOs.The reporting of Private Lateral Sewage Discharges is optional. 1.3 Objectives The primary objectives of the OERP are to protect public health and the environment, meet the requirements set forth by the SWRCB Order No. 2006-0003 and Order No. WQ 2013-0058-EXEC, and minimize risk of enforcement actions against the City. Additional objectives of the OERP are as follows: • Provide appropriate customer service; • Protect wastewater treatment plant and collection system personnel; • Protect the collection system,wastewater treatment facilities, and all appurtenances; and • Protect private and public property beyond the collection and treatment facilities. This plan shall not supersede existing emergency plans or standard operating procedures (SOPS), unless directed by the Utilities Manager or his superiors. 2.0 OVERFLOW RESPONSE PROCEDURE The Overflow Response Procedure presents a strategy for the City to mobilize labor, materials, tools, and equipment to correct or repair any condition that may cause or contribute to an unpermitted discharge.The plan considers a wide range of potential system failures that could create an overflow to surface waters (including the ocean), land (including the beach), or buildings. A summary of the Overflows Response Standard Operating Procedures is included in Appendix C. 2.1 Receipt of Information Regarding an SSO An overflow may be detected by City Staff or by others. During regular business hours (7:30 AM to 4:00 PM, Monday through Friday), calls from the general public regarding possible SSOs are routed to the Utilities Manager,who will notify the appropriate field staff and determine the most appropriate course of action.Table 2.1 summarizes the notification procedures of City Staff. June 2020 3 FAproj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\Appendices\Appendix G\OERP.doc Table 2.1 Primary Notification Procedures Overflow Emergency Response Plan City of Pismo Beach First Contact During Normal Working Hours(7:30 AM to 4:00 PM) Contact Utilities Manager(Russell Fleming) at 805.773.7075 After 4:00 P.M.,Weekends and Holidays Contact • Contact Standby Operator, at 805.441.7687. • If there is no response from Standby Operator within 30-minutes, contact Utilities Manager (Russell Fleming) by cell on file or Pismo dispatch 805.773.2208. Source: Data provided by City Staff During non-business hours and holidays,the City's designated "Standby Operator" is contacted at home or by cell phone. Following is a list of the City's current wastewater treatment systems operators,who serve as "Standby Operators," depending on schedules: • Hailie Hix • Justin Musick • Peter Fukushima • Jeff Gorham • Reno Evans If no response is received from the Standby Operator within 30-minutes of the call,then the Utilities Manager should be contacted by cell on file or by Pismo dispatch (805.773.2208). In order to respond to calls regarding SSOs efficiently, all relevant information regarding the SSO should be obtained from the caller.The following information regarding the SSO should be obtained from the reporting party: a. Name; b. Address; C. Telephone Number; d. Spill Location, Nearest Cross Street; e. Rate of Sewer Spill (gallons estimated) and Direction of Flow; f. Time; June 2020 4 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\Appendices\Appendix G\OERP.doc A Sanitary Sewer Overflow Report form (Appendix B) should be completed by field staff and other appropriate personnel within 24-hours of the SSO's confirmation.This report will aid the City in submitting an SSO report to the State Water Resources Control Board (SWRCB)through its online reporting system (the California Integrated Water Quality System, or CIWQS).This report is discussed in greater detail in Section 2.4. 2.2 Dispatch of Appropriate Crews to Site of Sanitary Sewer Overflow Failure of any element within the wastewater collection system that threatens to cause or causes an SSO will trigger an immediate response to isolate and correct the problem. Crews and equipment shall be available to respond to any SSO locations. Crews will be dispatched to any site of a reported SSO immediately. In addition, maintenance personnel shall be "on call" should extra crews be needed. 2.2.1 Dispatching Duties Dispatchers should receive notification of SSOs as outlined in Section 2.1 and dispatch the appropriate crews and resources as required.The Utilities Manager normally performs dispatching duties. 2.2.2 Crew Instructions and Work Orders Responding crews should be dispatched through the acting dispatcher(usually the Utilities Manager), and should receive instructions regarding appropriate crews, materials, supplies, and equipment needed. Dispatchers shall ensure that the entire message has been received and acknowledged by the crews who were dispatched.All standard communications procedures should be followed. All employees being dispatched to the site of an SSO shall proceed immediately to the site of the overflow.Any delays or conflicts in assignments must be immediately reported to the acting dispatcher for resolution. Response crews should report their findings, including possible damage to private and public property, to the acting dispatcher immediately upon making their investigation. If the acting dispatcher has not received findings from the field crew within a reasonable amount of time,they shall contact the response crew to determine the status of the investigation. The acting dispatcher shall refer all pertinent information to the next shift, including any details of the problems described by customers. The Utilities Manager is responsible for confirming that the Overflow Report was provided to the Regional Water Quality Control Board and County Environmental Health within the specified time. June 2020 5 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\Appendices\Appendix G\OERP.doc 2.2.3 Additional Resources The acting dispatcher will receive and shall convey to appropriate parties requests for additional personnel, material, supplies, and equipment from crews working at the site of an SSO. 2.2.4 Preliminary Assessment of Damage The response crew shall use discretion in assisting the property owner/occupant as reasonably as they can. In the event that damage to private property occurs, staff should seek approval of the property owner and contact the City's insurance adjuster to assess any damages. Appropriate still photographs and video footage, if possible, should be taken of the outdoor area of the sewer overflow and impacted area in order to thoroughly document the nature and extent of impacts. Applicable photographs are to be forwarded for filing with the Overflow Report. 2.2.5 Field Supervision and Inspection The Utilities Manager should visit the site of the overflow, if possible,to ensure that provisions of this overflow response plan and other directives are met. He is responsible for confirming that the Sanitary Sewer Overflow Report was completed and that the CIWQS online SSO Report is completed within the timeframes established in SWRCB Order No. 2006-0003.These timeframes are summarized in the City's SSMP. 2.2.6 Coordination with Hazardous Material Response Upon arrival at the scene of a sanitary sewer overflow, should a suspicious substance (e.g., oil sheen, foamy residue) be found on the ground surface, or should a suspicious odor(e.g., gasoline) not common to the sewer system be detected, the response crew should immediately alert the City's Fire Department. If safe to do so, staff shall stay at the site to await the arrival of the City's Fire Department to take over the scene. Upon arrival of the City's Fire Department, the response crew will take direction from the person with the lead authority of that team. Only when that authority determines it is safe and appropriate for the response crew to proceed can they then proceed with the containment, clean-up activities, correction, and reporting described in the Sewer Overflow Response Plan. 2.2.7 Crowd Control,Traffic Diversion, and Other Emergency Operations Should an SSO be of such a size or at such a location as to cause major disruptions to the flow of traffic at any point in the City,the responding crew shall notify the Utilities Manager as soon as possible.The Utilities Manager will then coordinate with the appropriate City Staff to set up a traffic diversion to move motorists away from the SSO location. Steps should be taken barricade off the site of an SSO to eliminate the potential of large crowds to inhibit the response crew's ability to effectively work.This is particularly important in areas of the June 2020 6 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\Appendices\Appendix G\OERP.doc City with a large number of visitors, such as the City's beaches. If necessary, additional assistance may be required (from the City's Police Department or other departments). 2.3 Overflow Correction, Containment, and Clean-Up SSOs of various volumes occur from time to time, in spite of concerted prevention efforts. Spills may result from blocked sewers, pipe failures, or mechanical malfunctions among other natural or man-made causes.The City is constantly on alert and should be ready to respond upon notification and confirmation of an overflow.This section describes specific actions to be performed by the crews during an SSO. The objectives of these actions are: • To protect public health, environment, and property from sewage overflows and restore surrounding area back to normal as soon as possible; • To establish perimeters and control zones with appropriate traffic cones and barricades, vehicles or use of natural topography(e.g., hills, berms); • To promptly notify appropriate regulatory agencies, including the SWRCB; • To contain the SSO to the maximum extent possible including preventing the discharge of sewage into surface waters; and • To minimize the City's exposure to any regulatory agency penalties and fines. Under most circumstances,the City will handle all response actions with its own maintenance forces, who have the skills and experience to respond rapidly and in the most appropriate manner. An important issue with respect to an emergency response is to ensure that the temporary actions necessary to divert flows and repair the problem do not produce a problem elsewhere in the system. For example, repair of a force main could require the temporary shutdown of the pump station and diversion of the flow at an upstream location. If the closure is not handled properly, sewage system back-ups may create other overflows. Circumstances may arise when the City could benefit from the support of private-sector construction assistance.This may be true in the case of large diameter pipes buried to depths requiring sheet piling and dewatering, should excavation be required.The City may also choose to use private contractors for open excavation operations that might exceed one day to complete. 2.3.1 Responsibilities of Response Crew Upon Arrival It is the responsibility of the first personnel who arrive at the site of an SSO to protect the health and safety of the public by mitigating the impact of the overflow to the extent possible. Should the overflow not be the responsibility of the City, but there is imminent danger to public health, public June 2020 7 FAproj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\Appendices\Appendix G\OERP.doc or private property, or to the quality of waters of the United States,then prudent emergency action should be taken until the responsible party assumes responsibility and provides actions. Upon arrival at an SSO,the response crew should do the following: • Determine the cause of the overflow, e.g. sewer line blockage, sewer line break, pump station mechanical or electrical failure, etc.; • Identify and request, if necessary, assistance or additional resources to correct the overflow or to assist in the determine of its cause; • Determine if private property is impacted. If yes, staff will advise County Environmental Healthl • Take immediate steps to stop the overflow, e.g. relieve pipeline blockage, manually operate lift station controls, repair pipe, etc. Extraordinary steps may be considered where overflows from private property threaten public health and safety(e.g., an overflow running off of private property into the public right-of-way); and • Request additional personnel, materials, supplies, or equipment that will expedite and minimize the impact of the overflow. 2.3.2 Initial Measures for Containment Following their preliminary assessment, the response crew will: • Initiate measures to contain the overflow and, where possible, recover sewage which has already been discharged, minimizing impact to public health or the environment • Determine the immediate destination of the overflow, e.g. storm drain, street curb gutter, creek, water body, etc. • Identify and request the necessary materials and equipment to contain or isolate the overflow, if not readily available • Take immediate steps to contain the overflow, e.g., block or bag storm drains, recover through vacuum truck, divert into downstream manhole, etc. 2.3.3 Additional Measures Under Potentially Prolonged Overflow Conditions In the event of a prolonged sewer line blockage or a sewer line collapse,the response crew will determine whether to set up a portable by-pass pumping operation around the obstruction. • Appropriate measures shall be taken to determine the proper size and number of pumps required to effectively handle the sewage flow. • Continuous or periodic monitoring of the by-pass pumping operation shall be implemented as required. • Regulatory agency issues shall be addressed in conjunction with emergency repairs. June 2020 8 FAproj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\Appendices\Appendix G\OERP.doc 2.3.4 Cleanup Sewer overflow sites are to be thoroughly cleaned after an overflow. No readily identified residue (e.g., sewage solids, papers, rags, plastics, rubber products) is to remain.Appropriate cleanup actions that shall be addressed, as applicable, are: • Where practical,the area is to be thoroughly flushed and cleaned of any sewage or wash- down water. Solids and debris are to be flushed, swept, raked, picked-up, and transported for proper disposal. • The overflow site is to be secured to prevent contact by members of the public until the site has been thoroughly cleaned. Posting if required should be undertaken pursuant to Section 3.1. • Where appropriate,the overflow site is to be disinfected and deodorized. • Where sewage has resulted in ponding,the pond should be pumped dry and the residue disposed in accordance with applicable regulations and policies. • Use of portable aerators may be required where complete recovery of sewage is not practical and where severe oxygen depletion in existing surface water is expected. • If a ponded area contains sewage which cannot be pumped/vacuumed dry, it may be treated with bleach. If sewage has discharged into a creek or other water body that may contain fish or other aquatic life, bleach or other appropriate disinfectant should not be applied and the California Department of Fish &Game should be contacted for specific instructions. • Equipment and tools used shall be thoroughly cleaned and returned to the storage locations that were used during the sewer spill abatement procedure.Vehicles shall be re-supplied with any materials used during the incident. In general,the following information should be recorded regarding the SSO abatement and clean up procedure: • Equipment and Manpower used; • Cause of Spill; • Volume of Spill; • Time of Spill Stoppage; • Duration of Spill; • Disinfection Performed; • State Whether Warning Signs Were Posted; • Time of Completion. June 2020 9 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\Appendices\Appendix G\OERP.doc 2.3.5 SSO Surface Water Mitigation The City shall take the appropriate steps to prevent surface water degradation as a result of an SSO. These steps will vary on a case-by-case basis, and may include the use of portable aerators or other means. Should an SSO result in a discharge to the ocean,the City, in conjunction with County Environmental Health Department and other appropriate departments or agencies, shall take immediate mitigation steps.These steps should include, as appropriate, posting warning signs, providing barricades, overflow containment, clean up and disinfection of the beach. 2.4 Overflow Report A Sanitary Sewer Overflow Report (Appendix D) shall be completed by response crews and designated City Staff and provide photographic or video graphic evidence to support all estimation and containment claims. The Utilities Manager shall be promptly notified when the overflow is eliminated. 2.5 Spill Estimation Use the methods outlined in (Appendix E) and worksheets (Appendix F) Methods for Estimating Spill Volume and the Spillonator to reenact flows and volumes when estimating the volume of the spilled sewage. Wherever possible, document the estimate using photos of the SSO site before and during the recovery operation. 2.6 Customer Satisfaction The Utilities Manager or response crew confirming the overflow should follow-up in person or by telephone with the citizen(s) reporting the overflow.The cause of the overflow and its resolution should be disclosed. 3.0 PUBLIC ADVISORY PROCEDURE In consultation with County Environmental Health, Wastewater Collection staff will post signs and place barricades, cones,traffic arrow board, and caution tape as needed to keep vehicles and pedestrians away from contact with spilled sewage. Creeks or drainage channels that have been contaminated as a result of an SSO should be posted at visible access locations until the risk of contamination has subsided to acceptable background levels.The warning signs, once posted, should be checked every day to ensure that they are still in place. Signs shall not be removed until directed by the Utilities Manager. Major spills may warrant broader public notice such as placing door tag in the surrounding neighborhood.The approval of the Director of Public Works/City Engineer is required prior to contacting local media when significant areas may have been contaminated by sewage. June 2020 10 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\Appendices\Appendix G\OERP.doc The City continues to work with County Environmental Health on public notification procedures following sanitary sewer overflows and will revise these procedures as necessary in the future to ensure public health and safety. 4.0 REGULATORY AGENCY NOTIFICATION PLAN The Regulatory Agency Notification Plan establishes procedures that the City shall follow to provide formal notice to the appropriate regulatory agencies as necessary in the event of SSOs. Agency notifications will be performed in parallel with other internal notifications.The procedures for providing notification of an SSO to the media are presented in Section 5. Internal notification and mobilization of personnel are detailed in Section 2. In general,the following persons shall be notified in the order specified below: 1. Utilities Manager 2. Public Works/Engineering 3. Required Agencies 4.1 SWRCB Notification Plan Using data supplied during the verification process and updates from the response crew,the appropriate City Staff designee shall prepare a Sanitary Sewer Overflow Report(Appendix D).This report will be used to complete the SWRCB online SSO Report through CIWQS. The City's authorized representative, Mr. Russell Fleming(Utilities Manager), may choose to establish a data entry designee for the completion of the CIWQS online SSO reports. Should one be established,this designee will use the data collected by the response crew, and the Sanitary Sewer System Overflow Report,to complete a draft SSO Report. Otherwise,the Utilities Manager will complete the draft SSO Report himself.This draft report shall comply with the time-frame requirements of the SWRCB order No. 2006-0003, as summarized in the City's SSMP.These requirements depend on the type of SSO that has occurred (i.e. Category 1, Category 2) The draft report will then be submitted to the Utilities Manager for review (if a data entry designee has been established).Additional data will also be collected as necessary. Upon review of the draft SSO Report, the Utilities Manager certifies the draft report through CIWQS. 4.2 Other Agency Notification The City is required to report wastewater overflows and discharges consistent with the California Water Code and the Health and Safety Code. Agency notification requirements vary depending on the quantity of sewage spilled and the location the spill reaches (Table 4.1).

The City has designated the following reporting persons for the notification of the preceding agencies: • Russell Fleming, Utilities Manager(805.773.7075). 5.0 MEDIA NOTIFICATION PROCEDURE When an overflow has been confirmed and is a threat to public health,the following actions should be taken, if necessary,to notify the media: • Response crew verifies overflow and reports back to the Utilities Manager. • The Utilities Manager,with the approval of his superiors, informs the appropriate City department responsible for public information.This department will report to the media of an overflow. • Calls received by the dispatcher from the media at any time are referred to the City department responsible for public information. • Only specified personnel within the City department responsible for public information should conduct interviews with the media. June 2020 12 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\Appendices\Appendix G\OERP.doc 6.0 FAILURE INVESTIGATION Following an SSO event, a failure investigation will be conducted to determine the cause of the SSO and identify corrective actions needed to reduce or eliminate the potential for the SSO to recur. The investigation will include reviewing all relevant data to determine appropriate corrective actions for the sewer line segment or lift station.The investigation will be conducted by the response team or Utilities Manager.The investigation will include: • Reviewing past maintenance records; • Reviewing original construction plans and regulatory reports; • Reviewing available photographs; • Conducting a CCTV inspection to determine the condition of the line segment immediately following the SSO and reviewing the video and logs; and; • Interviewing staff who responded to the spill, as well as interviewing customers and residents. The product of this investigation should be the determination of the cause of the SSO and identification of corrective actions. 7.0 SSO RESPONSE TRAINING This section provides information on the training required to support the City's Overflow Emergency Response Plan. All City personnel who may have a role in responding to, reporting, and/or mitigating a sanitary sewer overflow will receive training on the contents of the City's Overflow Emergency Response Plan. New employees will receive training before they are placed in a position where they may have to respond. Current employees will receive annual refresher training on this plan and the overflow emergency response procedures. All contractor personnel who may have a role in responding to, reporting to the City, and/or mitigating a wastewater collection system overflow will receive training on the contents of the Overflow Emergency Response Plan. Records will be kept of all training that is provided in support of the City's Overflow Emergency Response Plan. The records for all scheduled training courses and for each overflow emergency response training event will include date, time, place, content, name of trainer, and names of attendees. 8.0 DISTRIBUTION AND MAINTENANCE OF OERP The SSMP report recommends that the SSMP be reviewed at some pre-determined interval, such as annually,to determine where improvements can be made.This OERP should be updated in June 2020 13 F:\proj\2019\190108\5 Deliverables\Reports\SSMP.2019\Word Doc Chapters\Appendices\Appendix G\OERP.doc conjunction with the SSMP evaluations. Updates to the OERP should be made to reflect all changes in policies and procedures as may be required to achieve its objectives. 8.1 Submittal and Availability of OERP Copies of the OERP and any amendments should be distributed to all of the departments, divisions, and personnel that are heavily involved with the SSMP or OERP programs. All other personnel who may become incidentally involved in responding to overflows should be familiar with the OERP. A program to train such personnel on the provisions of this plan should also be considered by the City. 8.2 Review and Update of OERP The City is responsible for keeping the OERP up to date.The OERP should be reviewed at a predefined time interval, such as annually,for outdated material and should be updated whenever: • Directed by the Utilities Manager or his superiors; • The SSMP plan audit indicates that material needs to be revised or added; • Responsibilities of personnel involved in SSO response, mitigation or reporting change for various reasons; or • Governing laws, rules or regulations change.

AMENDED MONITORING AND REPORTING PROGRAM FOR THE STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS FOR SANITARY SEWER SYSTEMS BACKGROUND Water Code section 13193 (2001, AB. 285) requires the State Water Resources Control Board (State Water Board) and Regional Water Quality Control Boards (collectively Water Boards) to gather comprehensive and specific Sanitary Sewer Overflow (SSO) information. Water Code section 13193 also requires the Water Boards to make available to the public information including but not limited to the cause, estimated volume, location, date, time, and duration of the SSO; whether the SSO reached or may have reached surface waters; the response and corrective action taken by the collection system owner or operator (hereafter, Enrollee}for each SSO event; and the contact information for each Enrollee. On May 2, 2006 the State Water Board adopted Water Quality Order 2006-0003-DWQ, "Statewide Waste Discharge Requirements for Sanitary Sewer System (hereafter, SSS WDRs)to address Water Code section 13193 requirements and develop the framework for the statewide Sanitary Sewer Overflow Reduction Program. The SSS WDRs' Monitoring and Reporting Program (MRP) includes specific SSO notification and reporting and record keeping requirements to meet SSO reporting requirements in the Water Code and facilitate compliance monitoring and enforcement for violations. The State Water Board Executive Officer issued a revised MRP for the SSS WDRs on February 20, 2008 to rectify notification deficiencies that occurred early in program implementation and to ensure that first responders (e.g., Water Boards, California Office of Emergency Services,and County Health Departments)are notified in a timely mannerfor SSOs discharged to surface waters. Based on over six years of implementation of the SSS WDRs, the State Water Board concluded that the February 20, 2008 revised MRP is no longer adequateto advance the Sanitary Sewer Overflow Reduction Program objectives,assess compliance,and enforcethe requirements of the SSS WDRs. Following is January 24, 2012 workshop with stakeholders for the review and update of the SSS WDRs, the State Water Board directed staff to review and evaluate the existing monitoring and reporting requirements and prepare an amended MRP for the Executive Director's issuance.Staff worked with the key stakeholders (e.g.,California Association of Sanitation Agencies)to revise the monitoring and reporting requirements. State Water Board staff distributed the draft versions of the MRP to all stakeholders registered on the Lyris e-mail list for the Sanitary Sewer Overflow Reduction Program, solicited comments on the draft versions of the MRP in January and March 2013, and considered all comments received in developing the final revised MRP. INSPECTION AND AUDIT FINDINGS Since January 2007, numerous violations of the SSS WDRs have been documented by the Water Boards through data review,compliance mortoring, and onsite inspections. The most common violations related to the MRP that the Water Boards have documented are: • Failureto properly estimate and report SSO volumes discharged and recovered [violation of section G ofthe SSS WDRs] • Failure of the Enrollee to comply with all minimum MRP record keeping requirements [violation of section G of the SSS WDRs) • Failure of the Enrollee to implement feasible alternatives and actions necessary to identify and correct problems causing SSOs [violation of subsection D.6 of the SSS WDRs] • Unauthorized use of legally responsible official's SSO Online Database login password and electronic signature; [violation of section J of the SSS WDRs) • Failure of the Enrollee to develop and/or implement an Overflow Emergency Response Plan to ensure all reasonable steps are taken to contain and prevent the discharge of untreated and partially treated wastewater to waters of the United States and to minimize or correct any adverse impact on the environment resulting from the SSOs, including accelerated or additional monitoring necessary to determine the nature and impact of the SSO [violation of subsection D.13{vi) of the SSS WDRs] • Failure of the Enrollee to implement required training for sewer system operators and contractors [violation of subsections D.13{iv) and D.13(vi) of the SSS WDRs] Amendments madetothe MRP in Order 2013-0058-EXEC address these and otherissuesthat have become apparent in the implementation of the SSS WDRs in over six years. MONITORING AND REPORTING PROGRAM AMENDMENTS State Water Board staff and other members of the Data Review Committee reviewed the current SSS WDRs reporting requirements as part of the SSS WDRs review and update process. The Data Review Committee is open to all stakeholders.Consequently,enrollees, non-governmental organizations,and other agencies have participated. As a result of this process, new reporting requirements have been developed that address the compliance and enforcement issues noted above and improve the quaty and usefulness of SSO data collected. While the proposed changes streamline the reporting process overall, some fields have been added to the reports. These addtions address critical information gaps in the current reporting that have been identified both internally and by stakeholders. For example,many enrollees have noted thatwe need to be able to separate sewer lateral spills from spills occurring in other asset types like main lines or pump stations.The"where did the failure occur"question on the electronic spill report form was nota requiredfield inthe original or revised 2008 MRP.Many SSO reports do not have this information, thus,we cannot differentiate lateral spills from main line, pump station, or other types of spills. This is one example of the additions in the required data entry that have been addressed in the 2013 MRP revisions. The following is a summary of major changes made to the existing MRP (Order 2008-0002- EXEC) and incorporated in the final revised MRP (Order 2013-0058-EXEC): 1. Change in Notification Requirement for spills that reach surface water: • Three notification calls were required (California Office of Emergency Services, Regional Water Quality Control Boards, and local Health Departments). Required notification has been changed to call California Office of Emergency Services (Cal OES) only since Cal OES notifies the Regional Water Quality Control Boards and local Health Departments when a spill notification is received. • Elimination of requirement to submit a certification to Regional Water Quality Control Boards within 24 hours of making notification calls. • Alignment of notification requirementwith California Code of Regulations section 2250, Reportable Quantity of Sewage, by requiring notification calls for only spills of 1,000 gallons or more. Notification of Cal OES was required for all spills to surface water. • Addition of requirement to update Cal OES when there are substantial changes to previously reported spill volume estimates or impacts. 2. Defined new spill categories and refined spill report fields: • Replacement of spill Categories 1 and 2 with Categories 1,2, and 3. Spills are now classified as follows: • Category 1—Spillsof any volumethat reach surfacewater • Category 2—Spills greaterthan or equal to 1,000 gallons that do'not reach surface water • Category 3(formerly Category 2)—Spills less than 1,000 gallons that do not reach surface water All spills to surface water will be in a distinct category with this change. Spil reporting fields were refined and streamlined with stakeholder input. 3. Addition of requirement to submit a technical report within 45 days of the end date for spills to surface water over 50,000 gallons. 4. Addition of requirementfor all Permit enrolleesto develop a Water Quality Monitoring plan to be implemented withi n48 hours after initial notification for spills where 50,000 gallons or more reach surface water. - 5. Addtion of requirement for Permit enrollees to submit an electronic copy of their Sewer System Management Plan (SSMP) or provide the web address where their SSMP is posted. 6. Addition of enhanced record keeping requirements. 7. Elimination of requirement to certify Private Lateral Sewer Discharge reports. 8. Addition of a 120-day time limit for amending and re-certifying spill reports. Appendix B - WATER QUALITY MONITORING REQUIREMENTS AND SSO SAMPLING PLAN WATER QUALITY MONITORING REQUIREMENTS (from SSS WDR): To comply with subsection D.7(v) of the SSS WDRs, the enrollee shall develop and implement an SSO Water Quality Monitoring Program to assess impacts from SSOs to surface waters in which 50,000 gallons or greater are spilled to surface waters. The SSO Water Quality Monitoring Program, shall, at a minimum: 1. Contain protocols for water quality monitoring. 2. Account for spill travel time in the surface water and scenarios where monitoring may not be possible (e.g. safety, access restrictions, etc.). 3. Require water quality analyses for ammonia and bacterial indicators to be performed by an accredited or certified laboratory. 4. Require monitoring instruments and devices used to implement the SSO Water Quality Monitoring Program to be properly maintained and calibrated, including any records to document maintenance and calibration, as necessary,to ensure their continued accuracy. 5. Within 48 hours of the enrollee becoming aware of the SSO, require water quality sampling for, at a minimum, the following constituents: i. Ammonia ii. Appropriate Bacterial indicator(s) per the applicable Basin Plan water quality objective or Regional Board direction which may include total and fecal coliform, enterococcus, and e-coli. 1. Sewer System Overflow Sampling Plan: The City of Pismo Beach Wastewater Collection Staff will first determine whether or not the SSO has reached receiving water, by calculating travel paths, flow rates, and containment measures. If the spill is 50,000 gallons or greater and has come in contact with a receiving water, the SSO Sampling Plan will be followed. The receiving water will be monitored at three locations: 1) At the SSO discharge point to the receiving water. 2) Upstream from the point of the SSO. 3) Downstream from the point of the SSO. Three parameters will be monitored per Standard Methods or EPA protocol: 1) Ammonia. 2) Fecal Coliform. 3) Enterococci. Notify City's State certified, #2438,laboratory personnel of field sampling requirement related to spill over 50,000 gallons in waterway. In the event that the SSO occurs after hours, contact aforementioned laboratory at start of business hours the following morning. Use Personal Protective Equipment(PPE)while performing sampling. Proceed with testing and/or sampling only when it is determined to be feasible and safe. 1.1 Point of Discharge Sampling/Testing Step 1: Move to the point where the SSO entered receiving water. Step 2: Photograph,map and mark the location for future reference. Step 3:Label the field samples with the date,time,location,and sampler's initials Record the testing results. Step 4: Collect 2 bacteriological samples (Fecal Coliform and Enterococci) using the supplied containers labeled "micro". Step 5: Collect a 500 ml sample for ammonia using a plastic 16 oz container that contains H2SO4 (gold colored) preservative. Step 6:Keep the samples under ice or refrigeration until transferred to the laboratory's process refrigerator. • Use of a cooler 1.2 Upstream Sampling/ Testing Step 1: Move 10' upstream from the point where SSO enters the receiving water (to obtain a non- contaminated baseline sample). Step 2: Follow the procedure mentioned in"1.1 Point of Discharge Sampling/Testing" (Steps 2—6). 1.3 Downstream Sampling Step 1: Determine how far the SSO has traveled downstream • Estimate rate of flow of stream using established City of Pismo Beach SOP. • Use a floating item on the water to determine how far it travels in one minute x estimated number of minutes since SSO first reached the water. Then measure and record width of stream and in the same location measure the depth of stream in five locations from left to right. Step 2: Move to 3 locations downstream. • 50' and 200'downstream from the point where the SSO enters the receiving water and • A point nearest the extent of how far the SSO traveled following calculation in Step 1 Step 3: Follow the directions mentioned in "1.1 Point of Discharge Sampling/ Testing" (Steps 2 - 6) NOTE: (Do not touch micro sample container's opening rim or bottom of the lid once the lid is removed. Do Not overfill sample containers because they contain preservatives including concentrated acids and caustics that are dangerous and harmful if contacted with skin, eyes etc.) All samples should be labeled with location, date, time,preservation and other pertinent. Follow-up sampling and testing will be performed if determined to be necessary.A Technical report summarizing spill event and associated analytical results will be prepared and submitted within the required 45 days. Laboratory service hours are: Monday through Friday, 8AM to 5:30PM. Samples will be collected and preserved by the City's state certified laboratory using established SOP protocol and using per the Environmental Laboratory Accreditation Program (ELAP) certificate number#2438. Laboratory materials, reagents, and equipment are all maintained as a part of the laboratory's quality assurance program to produce legally defensible data as required by ELAP Appendix C - Overflows Response Standard Operating Procedures Overflow Response SOP The purpose of this Standard Operational Procedure (SOP) is to aid staff in prompt and responsible SSO response and is intended only as a condensed version of the Overflow Emergency Response Plan (OERP). Responding to SSOs • The Responder shall visit the site immediately in an attempt to minimize or eliminate an overflow. Respond with the Hydro Cleaning truck and/or spill response vehicle depending on the situation. • Upon arrival at the site,clearly assess the situation and comply with all safety precautions (traffic,confined space,etc.) and verify the existence of a sewer system spill or backup. • Identify and assess the affected area and extent/impact of the spill and request additional help as needed for line cleaning or repair, containment,recovery,lab analysis and site cleanup. • Using the appropriate cleaning equipment, set up downstream of the blockage and hydro clean upstream from a clear maintenance hole. Attempt to remove the blockage from the system and observe the flows to ensure that the blockage does not recur downstream. • If the blockage cannot be cleared within a reasonable time or conveyance system requires construction repairs, contingency plans must be employed as needed, including containment, bypass pumping, contractual assistance etc. If assistance is required,immediately contact other employees, contractors and equipment suppliers as required. • Use barricades, caution tape, cones, etc. as needed to keep the public away from a sewage release. Signs warning the public of a sewage release should be posted in the affected area if directed by the proper authority or Collection System Supervisor,Warning signs should remain posted until authorized removal. • If the spill reaches a drainage channel or water body, refer to the sampling requirements in Appendix B of the OERP. • The response crew shall complete the Spill report (OERP Appendix D) and forward to Collections Supervisor and Environmental Staff as stated at the bottom of the report. • SSO Notification and Reporting: Accurate and responsive reporting is vital. Refer to the SSO Reporting Requirement Flow Chart(OERP Appendix D).

This appendix documents the three methods that are most often employed. The person preparing the estimate should use the method most appropriate to the sewer overflow in question and use the best information available. Method 1: Eyeball Estimate The volume of small spills can be estimated using an"eyeball estimate".To use this method imagine the amount of water that would spill from a bucket or a barrel. A bucket contains 5 gallons and a barrel contains 50 gallons. If the spill is larger than 50 gallons, try to break the standing water into barrels and then multiply by 50 gallons. This method is useful for contained spills up to approximately 200 gallons. Method 2: Measured Volume The volume of most small spills that have been contained can be estimated using this method. The shape, dimensions, and the depth of the contained wastewater are needed. The shape and dimensions are used to calculate the area of the spills and the depth is used to calculate the volume. Common Shapes and Dimensions RECTANGLE CIRCLE TRIANGLE AL �L' E D G T H H T 4am LENGTH BASE Step 1 Sketch the shape of the contained sewage (see figure above). Step 2 Measure or pace off the dimensions. Step 3 Measure the depth at several locations and select an average. Step 4 Convert the dimensions,including depth, to feet. Step 5 Calculate the area in square feet using the following formulas: Rectangle: Area = length (feet) x width (feet) Circle: Area = diameter (feet) x diameter (feet) x 0.785 Triangle: Area = base (feet) x height (feet) x 0.5 Step 6 Multiply the area (square feet) times the depth (in feet) to obtain the volume in cubic feet. Step 7 Multiply the volume in cubic feet by 7.5 to convert it to gallon Method 3: Duration and Flow rate Calculating the volume of larger spills,where it is difficult or impossible to measure the area and depth,requires a different approach. In this method,separate estimates are made of the duration of the spill and the flow rate.The methods of estimating duration and flow rate are: Duration The duration is the elapsed time from the time the spill started to the time that the flow was restored. Start Time:The start time is sometimes difficult to establish. Here are some approaches: 1. Local residents can be used to establish start time. Inquire as to their observations. Spills that occur in rights-of-way are usually observed and reported promptly. Spills that occur out of the public view can go on longer. Sometimes observations like odors or sounds (e.g. water running in a normally dry creek bed) can be used to estimate the start time. 2. Changes in flow on a downstream flowmeter can be used to establish the start time. Typically the daily flow peaks are "cut off' or flattened by the loss of flow. This can be identified by comparing hourly flow data during the spill event with flow data from prior days. This method will likely only be effective with consistent weather. 3. Conditions at the spill site change over time and can be used to establish the start time. Initially there will be limited deposits of toilet paper and other sewage solids. After a few days to a week, the sewage solids form a light-colored residue. After a few weeks to a month, the sewage solids turn dark. The quantity of toilet paper and other materials of sewage origin increase over time. These observations can be used to estimate the start time in the absence of other information. Taking photographs to document the observations can be helpful if questions arise later in the process. This method is valid for spills that have been occurring for a long time and may be used in conjunction with either of the above methods. 4. It is important to remember that spills may not be continuous. Blockages are not usually complete (some flow continues). In this case the spill would occur during the peak flow periods (typically 10:00 to 12:00 and 13:00 to 16:00 each day). Spills that occur due to peak flows in excess of capacity will occur only during, and for a short period after, heavy rainfall. End Time: The end time is usually much easier to establish. Field crews on-site observe the "blow down" that occurs when the blockage has been removed. The "blow down" can also be observed in downstream flowmeters. Flow Rate The flow rate is the average flow that left the sewer system during the time of the spill. Two common ways to estimate the flow rate: 1. Flowmeter: Changes in flows in downstream flowmeters can be used to estimate the flow rate during the spill. 2. Counting Connections: Once the location of the spill is known, the number of upstream connections can be determined from the sewer maps. Multiply the number of connections by 200 to 250 gallons per day per connection or 8 to 10 gallons per hour per connection. For example: 22 upstream connections * 9 gallons per hour per connection = 198 gallons per hour / 60 minutes per hour = 3.3 gallons per minute Spill Volume Once duration and flow rate have been estimated,the volume of the spill is the product of duration (hours or days) and the flowrate (gallons per hour or gallons per day). For example: Spill start time = 11:00 Spill end time = 14:00 Spill duration = 3 hours 3.3 gallons per minute x 3 hours x 60 minutes per hour = 594 gallons Appendix F1- Spill Estimation Worksheets (Area and Volume) Area and Volume PURPOSE The purpose of this guide is to assist with the estimation of the Volume of a Sewage Spill. It has limited application, as it can be used on dry surfaces where the limits of the spill footprint can be determined and in instances when the spill is contained. It does not require that the Spill Duration and Spill Flow Rate be known. However, any and all information available should be used if it helps to make a more accurate estimate. HOW IT WORKS This guide contains formulas for determining the volume of some basic geometric shapes and some simple conversions that are necessary to determine volume (in gallons.) Any sewage spill will leave a`wetted footprint'on the surfaces affected. This guide will help you to determine the area of the wetted footprint of the spill. The wetted footprint will not likely be a geometric shape that is easy to determine the area. You will have to be creative and find the familiar shapes within the shape. This will be demonstrated later in the guide. After determining the area contacted by the spill,the depth of the spilled sewage must be determined, which,combined with the area,will lead to the volume spilled. CONVERSIONS Chart A Conversion: **To convert inches into feet: Divide the inches by 12. Inches to Feet Example: 27" / 12 = 2.25' 1/8" = 0.01' 1/4" = 0.02' Or Use Chart A 3/8" = 0.03' 1/2" = 0.04' Example: 1 3/4" = ? 5/8" = 0.05' 3/4" = 0.06' 1" (0.08') + 3/4" (0.06) = 0.14' 7/8" = 0.07' 1" = 0.08' 2" = 0.17' 3" = 0.25' 4" = 0.33' 5" = 0.42' ** One Cubic Foot can contain 7.48 gallons of liquid. 6 = 0.50 7" = 0.58' 8" = 0.67' 9" = 0.75' 10" = 0.83' 11" = 0.92' 12" = 1.00' GEOMETRY For the purposes of this guide, the unit of measurement will be in feet for formula examples. Area is two-dimensional- represented in square feet. (Length x Width) Volume is three-dimensional- represented in cubic feet. (Length x Width x depth) or (Diameter Squared) DZ x 0.785 x depth. A Note about Depth Wet Stain on a Concrete Surface - For a stain on concrete,use 0.0026'. This number is 1/32" converted to feet. For a stain on asphalt use 0.0013' (1/64"). These were determined to be a reasonable depth to use on the respective surfaces through a process of trial and error. A known amount of water (one gallon) was poured onto both asphalt and concrete surfaces. Once the Area was determined as accurately as possible, different depths were used to determine the volume of the wetted footprint until the formula produced a result that (closely) matched the one gallon spilled. 1/32"was the most consistently accurate depth on concrete and 1/64" for asphalt. This process was repeated several times. Sewage "Ponding" or Contained—Measure actual depth of standing sewage whenever possible. When depth varies, measure several (representative) points, determine the average and use that number in your formula to determine volume. Area/Volume Formulas Area is two dimensional and is represented as Square Feet (SQ/FT) Volume is three dimensional and is represented as Cubic Feet (CU/FT) One Cubic Foot can hold 7.48 gallons AREA/VOLUME OF A RECTANGLE OR SQUARE Formula: Length x Width x Depth = Volume in Cubic Feet Chart A Conversion: Inches to Feet - 1/8" 0.01' 1/4" = 0.02' 12' Depth = 1 3/" 3/8" = 0.03' 1/2" = 0.04' 5/8" = 0.05' 3/4" = 0.06' 25' 7/8" = 0.07' 1" = 0.08' 2" = 0.17' Length (25') x Width (12') x Depth (0.14') 3" = 0.25' 4" = 0.33' " = 0.42' 25' x 12' x 0.14' = 42 Cubic Feet. 5" = 0.42' 7" = 0.58' 8" = 0.67' Now the Volume in Cubic Feet is known. 9" = 0.75' 10" = 0.83' There are 7.48 Gallons in one Cubic Foot 11" = 0.92' So, 42 Cubic Feet x 7.48 gallons/cubic feet = 314 Gallons AREA/VOLUME OF A RIGHT TRIANGLE Chart A Conversion: Inches to Feet Base x Height x 0.5 x Depth = Volume in Cubic Feet 1/8" = 0.01' 1/4" = 0.02' 3/8" = 0.03' 1/2" = 0.04' 5/8" = 0.05' 3/4" = 0.06' 7/8" = 0.07' 1" = 0.08' 2" = 0.17' 3" = 0.25' 10' Depth = 5/8" 33 5" = 0.

If this was the shape of your spill, break it down, as best you can,with the shapes we know. If the spill depth is of varying depths, take several measurements at different depths and find the average. 1. Determine the volumes of each shape. In this example, after the volume of the circle is determined, multiply it by 55%(+/-)so that the overlap area won't be counted twice. 2. Add all the volumes to determine total spill volume. Step 1 NOTE: This can be used in a (Dry)dirt or grassy area that is not regularly irrigated like a field or If the spill affects a dry, a dirt parking lot. unimproved area such as a field or Wet weather would make this method dirt parking lot,determine the ineffective. Area of the wetted ground in the same manner as you would on a hard surface. Using a round-point 2" shovel,dig down into the soil until you find dry soil. Do this in several 1.5" locations within the wetted area and measure the depth of the wet soil. Average the measurement/thickness of the 1.25" wet soil and determine the average depth of the wet soil. 3" Step 2 Take a Test Sample 5" (See Next Page) 1.25" 2"+ 1.5"+ 1.25"+3"+ 5"+ 1.25"= 14.0„ EXAMPLE: 14.0"/6 measurements=2.33" If the Area of the spill was determined to be 128 Sq/Ft Average Depth =2.33"(0.194) and the average depth of the wet soil is 2.33 inches: 128 Sq/Ft x 0.194' =24.83 Cu/Ft 24.83 Cu/Ft x 7.48 Gals/Cu/Ft= 185.74 gallons 185.74 x 18%=33 Gallons(water in soil) (Test) SAMPLING SOIL FOR WATER CONTENT Once you have determined the wetted footprint of the spill,you will want to determine the water (sewage) content in the soil. 1. Select an area of dry soil (near the wetted footprint of the spill) to sample. 2. Pour a known amount of water onto the soil and let it soak in for an adequate amount of time. If possible,use a form to keep the water contained to a geometric shape (circle, square,rectangle,etc.). 3. Determine the Area of the wetted footprint. 4. Using a small hand tool, dig down into the soil until dry soil is reached. Measure the depth of the wet soil. Do this in multiple locations and average the measurements. 5. Multiply the Area by the Average Depth of the wet soil to determine the volume of the wet soil. 6. Determine the water content in the soil a. Since you started with a known amount,you know how much water is in the soil. b. Divide that known amount by the volume determined in step 5 to arrive at the percent of water content in the soil. c. Arrive at the water content of the soil (percent) Example: 1. Place a 2-foot diameter form onto an area of dry soil. 2. Pour one gallon of water into the form and let it soak in for 15 minutes. 3. Pull the form and measure the Area of the wetted soil (it will likely be larger than the form). Let's say 26" diameter. 4. Dig into the soil in 3 locations and measure the depth of the wetted soil. 5. Average the 3 measurements. (Let's say 2.5", 1.5" &3.75" = 7.75". divide by 3 = 2.58" or 0.215') 6. Determine the Area of the Circle (D2 x 0.785) 2.16'x 2.16'x 0.785 = 3.66 Sq/Ft 7. Multiply the Area by the Average Depth to get the Volume (3.66 x 0.215' = 0.79 Cu/Ft) 8. Multiply 0.79 cubic feet by 7.48 gallons/Cu/ft = 5.9 gallons. 9. Divide 1 Gallon (known Amount) by 5.9 gallons = .17 or 17%is the water content in the soil. 10. Now you have determined that the water content in the soil is 17%. Apply this to your actual spill area.

During Wet Weather conditions consult the Technical Services Department (TSD) for flow characteristics based on current conditions. A residential building is typically one EDU. For commercial buildings: • Refer to Service Line in the WWMS database for actual EDU's, or • Contact the District's Administration office. o Provide the Administration personnel with the address and they will provide the information. For small portions of the collection system such as a residential neighborhood the District's Grid Map Book can be used. 1. Locate the portion of the system in the Grid Map Book 2. Determine the limits of the collection system that flows through the overflowing manhole 3. Count the number of lots that are served by that portion of the collection system.

Many times, a combination of methods will need to be employed. Here are some approaches: Nearby Witnesses: Local residents can be used to establish start time. Inquire as to their observations. Spills that occur in public rights-of-way (streets, shopping centers, etc.) are usually observed and reported promptly. Spills that occur out of the public view (fields, access roads, etc) can go on longer. Observed Flow Rate + Volume: If the flow rate and volume spilled can be reasonably determined, this information can be used to work backwards to better determine the spill start time. Example. If the spill was discovered at 9:00 am, crews determined the spill rate was 10 GPM and you were able to completely contain and measure the spill,which was 540 gallons. The spill end time was 9:26 am. 540 gals / 10 GPM = 54 minutes. Spill end time was 9:26. Go back 54 minutes from the spill end time and you would arrive at a spill start time of 8:32 am. This assumes that the flow rate was the same throughout the entire spill. You can consider the diurnal flow patterns,if available, and fine- tune the start time. Flow meter Data: On larger trunk lines, changes in flow on a downstream flow meter can be used to establish the start time. Typically the daily flow peaks are"cut off' or flattened by the loss of flow. This can be identified by comparing hourly flow data during the spill event with flow data from prior days. For smaller lines,use flow data to determine typical flow for the same time period of the spill event. Though flows are not exactly the same for the same time period each day, an average of several days can be used to establish a reasonable flow rate. Site Conditions: Conditions at the spill site change over time. Initially there will be limited deposits of toilet paper and other sewage solids.After a few days to a week, the sewage solids form a light- colored residue. After a few weeks to a month, the sewage solids turn dark. The quantity of toilet paper and other materials of sewage origin increase over time. These observations can be used to estimate the start time in the absence of other information. Taking photographs to document the observations can be helpful if questions arise later in the process. Accounting for Flow Variation: It is important to remember that spills may not be continuous. Blockages are not usually complete (some flow continues). Refer to City diurnal flow patterns for typical flow variations. Response personnel should open the manhole downstream from the blockage and,if flow is observed,measure, document and take pictures. Spills that occur due to peak flows in excess of capacity will occur only during, and for a short period after, heavy rainfall. Use City rainfall data as appropriate. End time: The end time is usually much easier to establish. Field crews on-site observe the "blow down" that occurs when the blockage has been removed. The "blow down" can also be observed in downstream flow meters. Appendix F5- Spill Estimation Worksheets (Single Home Spill Estimation) Spill Estimation Single Home 150 GPD per Household (City-wide diurnal flow patterns are applied to estimate usage during each period) R 6 AMM A D (40%) (5%) 0.20 GPM 0.03 GPM Spill Rate Spill Rate Noon Midnight (30%) (25%) ■ 0.15 GPM 0.13 GPM Spill Rate Spill Rate B C 6 PM Time Period Gals per Minute Gals per Hour Gals per Period A - 6 AM to Noon 0.20 12.0 72 B - Noon to6PM 0.15 9 54 C - 6PM to 9 PM 0.13 7.5 45 D - 9 PM - Midnight 0.03 1.5 9 Spill Start Time - Spill End Time = Spill Duration Spill Duration x Spill Rate x EDUs = Spill Volume This estimation method works only for spills where the blockage is in the lower lateral. It assumes 150 gallons per EDU,which is based on the City-wide average. When a spill affects landscaped areas, dirt, fields or any surface that tends to absorb the spill,it is often difficult to use the `eyeball method' to make a valid estimation. This method will be useful in these cases. Once the Spill Start Time and End Time are determined, this method can be applied. Example: It is determined that the spill start time was 9:45 AM and the Spill End time was 1:30 (3 hours and 45 minutes) From 9:45 to Noon (2 Hrs, 15 Minutes would be calculated using 0.20 GPM (135 minutes x 0.20 = 27.0 gallons). From Noon to 1:30 PM (1 Hr, 30 Minutes would be calculated using 0.15 GPM (90 minutes x 0.15 = 13.5 gallons). Total would be 27.0 gallons + 13.5 gallons = 40.5 gallons. This information alone likely does not tell the whole story. Typically, sewage does not run continuously from a home. If at all possible the resident should be interviewed. Be respectful and ask the resident if they would mind if you asked them a few questions to help determine the volume of the spill. Example: Since the time you noticed the spill: • How many people have been home? • Have you done any laund (30 gallons/load) or ran the dish washer (9 gallons/load) or taken a shower (25 gallons) Next,put all of the information you have gathered: • The size of the stain or water mark on the ground + any tissue, etc. • The answers to the questions about use. • The volume the Spill Estimation Method suggested Does the information gathered suggest that the volume determined by the estimation tool be adjusted,up, down or the left as is?

A grease trap is a device designed and installed in order to separate and retain grease and oil from the normal wastes and permit normal liquid wastes to discharge into the sewer system. In the City of Pismo Beach service area, grease traps are a major concern for all of us, since the leading industry is tourism. In order to accommodate these tourists, the City of Pismo Beach provides some varied and unique restaurants. Presently, there are over fifty of these establishments serving the area and a proportionate amount of grease and oil derived from their operation is entering the regional sewer system and creating pumping and processing problems. This excess of grease and oil is mainly due to inefficient pretreatment practices. With installation and proper maintenance of grease traps/interceptors, there should be a minimum amount of grease and oil entering the sanitary sewer system, therefore reducing the problems at the City of Pismo Beach pump stations and the Wastewater Treatment Plant. Our goal at the City of Pismo Beach Wastewater Treatment Division is to make sure every industry and commercial business activity in the City of Pismo Beach service area is providing the proper pretreatment for their wastewater as mandated by the Regional Water Quality Control Board, Environmental Protection Agency as well as our own Sewer Use Ordinance. How Does A Grease Trap Operate? A grease trap is a relatively simple device composed of a flow restrictor, an inlet, two or three baffles (depending on the brand), a lid and airtight seal, and an outlet. Baffles are scientifically placed to allow efficient separating of grease and oils and are easily removable. Water draining to the grease trap passes through a flow control fitting which regulates the velocity of the water to the capacity of the trap. As the water enters the grease trap at this controlled rate of flow it is free of turbulence. It then passes over a series of separator baffles that are designed to cause greases, fats and oils to become separated and released from the wastewater. Once released, these contaminants rise to the top of the grease trap by natural flotation and are accumulated until removed. The wastewater now relieved of over 90 per cent of the contaminant oils and greases, continues to flow through the trap/interceptor and into the sanitary sewer system. Separation efficiencies for each trap are determined by the shape of the inlet, outlet baffles, and by flow travel characteristics within the trap. Separation efficiency decreases as the retained 1 VISMp& 9LIFOR�l volume of grease/oil products increases. For example, a 40-pound grease trap may have 95 per cent separation efficiency with no grease present in the trap and only 20 per cent separation efficiency with a full 40 pounds of grease in the trap. In other words, the more grease in the grease trap, the less grease will separate from the water and float to the top. Instead, the grease will go down the drain, with the rest of the water and thus defeat the whole purpose of having the grease trap. It is, the responsibility of each restaurant as a regulated business activity to ensure the pretreatment of wastewater by performing the following tasks: 1. Make sure the FLOW RESTRICTOR is present 2. Make sure ALL appropriate PLUMBING FIXTURES drain through the trap/interceptor 3. Make sure the BAFFLES are present(two or three, depending on the brand) 4. Make sure the trap is CLEANED as often as necessary to ensure that the grease/oil is separating out from the water; this will vary from restaurant to restaurant 5. Make sure the attached MAINTENANCE LOG is completed every time maintenance is performed on the trap/interceptor and that it is posted nearby for inspection. CLEANING GREASE TRAPS Every grease trap/interceptor needs to be cleaned. The length of time between cleanings will vary with the type and size of the grease trap/interceptor relative to the amount of grease and oil washed down the sink to the trap. If the sink in which the greasy pots and/or dishes are washed is not connected to the grease trap, then, of course, no grease will be collected in the trap at all (just on the inside of the restaurants'drain pipes). Many restaurants clean their grease traps each week at a designated time and day(i.e., Wednesday evenings after closing or Sunday morning before opening). It is beneficial to clean the trap often for the following reasons: 1. Keeps the rancid grease and oil odors at a minimum 2. Helps keep the grease from emulsifying (mixing with water) and then going down the drain Grease Interceptor/Grease Trap Maintenance Procedure for Food Preparation Facilities The City of Pismo has implemented a Regional Grease Program in our service area to reduce the amount of grease entering the sanitary sewer system from food serving establishments. Incorporated with this program is the need for proper cleaning and maintenance of grease interceptors and grease traps located at these establishments. 2 VISMp& 9LIFOR�l In order to meet all City requirements and keep these food serving establishments in full discharge compliance, the following procedures should be followed for servicing these grease removal units: Grease Interceptors shall be completely pumped (i.e.- dry-pumped removing the grease mat, liquids, sludge, and wash down material from the interior walls). Grease Traps shall be completely pumped (i.e.-dry-pumped removing the grease mat, liquids, and solids from walls, screens, baffles and air-relief chambers). Report any problems/damage with the interceptor/trap to the business manager/owner and the City of Pismo Beach Pre-treatment Inspector(i.e.- missing or broken baffles, screens, and pipes). The City of Pismo Beach prohibits the discharge of wastes pumped from a grease interceptor/trap back into the sanitary sewer or the clean interceptor/trap. Bacteria products used in the maintenance of interceptors or traps must be pre-approved by the City of Pismo Beach. Products having a content of enzymes, surfactants or solvents that is greater than 10% of the volume will not be approved for use. The City of Pismo Beach appreciates your cooperation in this matter. Please contact the Wastewater Treatment Plant Pre-treatment Inspector at(805) 773-7067 if you have any questions concerning the above requirements. 3 4 PISMp d` 9LIFOVL CITY OF PISMO BEACH Grease Interceptor Maintenance Log D.

Their purpose is to limit the discharge of FOG by the FSE to the extent possible. Not all BMPs may be applicable to all users; therefore, the following should be used as a starting point for the development of individualized BMPs. BMP 1 — Employee Training and Awareness The success of any FOG reduction program is dependant mainly on the participation of the individuals involved in such a program. It is therefore crucial to the success of the BMPs that employees and individuals be appropriately trained on the provisions thereof. Each FSE should do the following to establish adequate employee training and awareness procedures: • Train all employees on the provisions of the FSE's individual BMP program; • Require that employees follow the BMPs; • Instruct employees not to dispose of FOG into sinks; • Post "No Grease" signs above sinks and other appropriate discharge points (the language on these signs is dependent upon the business). BMP 2 — Garbage Disposal Limitation A large volume of FOG can be eliminated from the sanitary sewer system by limiting or eliminating the discharge of food particles to the system. The use of garbage disposals is discouraged for this reason. Food particles should be discharged into the trash rather than a sink drain. Additionally, the use of drain screens is recommended to capture food and other particles from being discharged into the sanitary sewer system. These screens should be cleaned frequently and emptied into the trash. FSE Best Management Practices 1 BMP 3 — Spill Clean UP FSEs should develop applicable practices to limit the amount of spills that occur. These spills cause unneeded discharge of FOG into the sanitary sewer system. Clean up of any spills that do occur should follow these guidelines: • Stop the spill at its source; • Perform a 'dry" clean up if possible. Use paper towels, brooms, rubber scrapers, or other means to dispose of the spilled food particles or FOG to the trash; • If a "dry"cleanup is not possible, follow these guidelines; o Clean up as much as possible with rags; o Use granular or absorbent material (such as sand, cat litter, sawdust, etc.) o Remove spilled material to the trash; o Mop or wash as sparingly as possible and discharge to the sanitary sewer system. Each FSE and other FOG producer should have a plan that will be followed in the event of a spill. This should include a step-by-step procedure that is known by all employees, as well as a responsible person who will monitor cleanup measures. Training to employees on such a plan should be periodically provided to employees. BMP 4— Equipment Cleaning and Maintenance When cleaning and maintaining equipment, it is possible to reduce the amount of FOG that enters the sanitary sewer system. This may include emptying or removing grease from equipment prior to washing and placing in the trash. The use of other "dry" cleaning methods, such as use of paper towels rather than water rinsing, is also encouraged. BMP 5 — Grease Handling and Disposal Oils, grease, or other oily liquids (such as salad dressing) should not be discharged in large quantities into the sanitary sewer system. These materials should be recycled, if possible. BMP 6 — Grease Traps To properly perform, grease traps should be adequately sized and installed in accordance with the requirements of the City. They should also be located in such a way as to facilitate cleaning. FSE Best Management Practices 2 It is recommended that each FSE inspect and clean its grease trap as often as is necessary to ensure proper performance. Cleaning and inspection records for each FSE shall be completed and kept on file for three years. Grease collected from grease traps should be disposed of through appropriately licensed disposal companies. BMP 7 — Residential and Private Dwellings It is important to note that not all FOG problems are caused by FSEs. In certain cities, residential FOG discharge may be a significant amount of the City's FOG production. For this reason, it is recommended that residential customers also adopt the aforementioned BMPs as applicable.
