The SSMP document consists of the City's policies, procedures, and programs for the safe, effective, and compliant operation of Rosemead's wastewater collection system, and is required to be periodically updated and approved by the local governing body to ensure compliance and improve system management. On October 9, 2018, the City Council adopted Resolution No. 2018-61 approving the Sewer System Management Plan (SSMP) as mandated by the State of California, General Waste Discharge Requirements (GWDR) for sanitary sewer systems Order No. 2006-0003. In 2022, the State Water Resources Control Board adopted General Order 2022-0103-DWQ, updating the previous order (Order No. 2006-0003-DWQ) requiring all agencies that own or operate a sanitary sewer system to develop and maintain a Sewer System Management Plan that details City sewer system operations, maintenance, and emergency response procedures and programs. The update reflected changes such as modern risks, including discharges to waters of the State as opposed to only waters of the United States, full electronic reporting, and enhanced system maintenance and resilience expectations. The City of Rosemead's local sewer system provides wastewater collection service to a population of approximately 51,185 (2020 Census), as well as numerous commercial and industrial customers. The sanitary sewer system consists of approximately 79 miles of gravity sewer mains ranging in sizes from 6 -inches to 12 -inches in diameter and assisted by one pump station. The City's collection system discharges to the Los Angeles County Sanitation District trunk sewers at various locations within the City. The City of Rosemead's sewer system is entirely within the Consolidated Sewer Maintenance District (CSMD) and Los Angeles County Sanitation District No. 15. The AGENDA ITEM 5.I City Council Meeting December 9, 2025 Page 2 of 3 local sewage system is under the jurisdiction of the City of Rosemead and is operated and maintained by the Los Angeles County Department of Public Works.

FINAL- November 30, 2025 1 vii Sewer System Management Plan Rosemead /Los Angeles County Public Works Goal and Introduction 1.1 Regulatory Context The City of Rosemead along with Los Angeles County Public Works (LACPW) has prepared this updated Sewer System Management Plan (SSMP) pursuant to the State Water Resources Control Board (SWRCB) December 6, 2022, Statewide Sanitary Sewer Systems General Order 2022- 0103-DWQ (General Order). This SSMP provides a management plan for Los Angeles County Department of Public Works (PWj, which administers the following Sewer Maintenance Districts (Districts) in Los Angeles County responsible for operating and maintaining the collection systems: a Consolidated Sewer Maintenance District (CSMD); and a Marina Sewer Maintenance District (MSMD); In addition, through service agreements, PW operates and maintains the collections systems for the Cities of Irwindale, West Hollywood, and Montebello. This SSMP provides a management plan for Rosemead, which is part of the CSMD. Table 1-1 summarizes the General Order requirements addressed by this SSMP'. These requirements are defined by General Order specifications and associated General Order attachments. All agencies that own and operate collection systems greater than one mile in length must comply with these requirements. Table 1-1: Summary of General Order Requirements and implementation of a SSMP Requires City to certify and upload the SSMP to CIWQS Entire SSMP Entire SSMP Requires update of the SSMP every 6 years, ata minimum. Requires governing board approval of SSMP. Requires Entire SSMP City to certify and upload SSMP to CIWQS. Requires IACPW to include and implement system- D.4 Operations and specific procedures to proactively prioritize operations and Maintenance maintenance, condition assessments and repair and D.8 System Evaluation, rehabilitation to address system resilience Capacity Assurance and Capital Planning Requires City to maintain system rapacity to convey dry D.8 System Evaluation, weather and forecasted wet weather flows Capacity Assurance and Capital Planning ' Summarized from the SWRCB Order No. 2022-0103-DWQ Statewide Waste Discharge Requirements General Order for Sanitary Sewer Systems Sewer System Management Plan Rosemead /Los Angeles County Public Works Table 1-1: Summary of General Order Requirements Requires City and LACPW to maintain in good working order and operate as design any facilities, treatment or 0.4 Operations and control systems design to contain and convey sewer. Maintenance D.8 System Evaluation, Capacity Assurance and Capital Planning This document serves as the 2025 update to the SSMP approved and adopted by the City Council at a public meeting. Appendix Al includes documentation of approval by the Board. Appendix A2 includes the General Order. The sewer -related services that the Districts provide vary from city to city depending on the service agreements. Table 1-2 summarizes the CSMD cities and the sewer -related services currently provided by the LACPW to each of the cities. LACPW applied for coverage under the reissued General Order for facilities it owns, and the CSMD member cities applied for coverage under the reissued General Order for facilities they own. LACPW and the member cities own the sewer mainlines and the point of connection to the sewer mainlines, but do not own any portion of the sewer lateral beyond the sewer connection. LACPW, as operator of the CSMD and MSMD, prepares and updates the SSMP for activities LACPW perform for managing, operating, and maintaining sewer systems including the Districts. The cities, as well as the other County departments serviced by CSMD, as owners of their respective systems, are responsible for preparing and updating an SSMP specific to the collection system owned by those entities. Some cities within the CSMD have either adopted the Los Angeles County Code or have established local ordinances or resolutions governing the performance of items stipulated in the General Order. Cities are responsible for implementing the legal authorities required by the General Order. Cities also are responsible for conducting capacity studies of their collection system when necessary and correcting identified hydraulic deficiencies. The CSMD performs functions required by the General Order related to the operation and maintenance of sanitary sewer systems. A pdf copy of this SSMP is available on the intemet at: LACPW: hftps://dpw.lacounty.gov/sewer/ssmi).pdf Rosemead: hftps://www.rosemeadca.gov/services/i)ublic works/engineering services/sewer system management plan.php 12 Sewer System Management Plan Rosemead /Los Angeles County Public Works Table 1-2: LACDPW Sewer -Related Services to the 38 CSMD Cities' x X X X X X X X X X X X 13 Sewer System Management Plan Rosemead /Los Angeles County Public Works Table 1-2: LACDPW Sewer -Related Services to the 38 CSMD Cities' 'Through the General Services Agreement, a city can request LACPW resources upon specific request LACDPW currently provides at least some degree of service to all 88 cibes in the County of Los Angeles. 1.2 SSMP Goal and System Management Objectives The goal of the SSMP is to provide a plan and schedule to properly manage, operate, and maintain all parts of the collection system. This will help reduce and prevent spills, as well as mitigate any spills that do occur. The City and LACPW has adopted and is dedicated to achieving the following collection system management objectives: • Proper operation, maintenance, and management of the Districts' sanitary sewer collection system facilities to reduce the frequency and severity of sewer spills and their potential impacts on public health, safety, and the environment. • Prompt action when sewer spills occur to identify, contain, and remove the cause, promptly report the event to appropriate regulatory authorities, and ensure the public is adequately and timely notified. • Document all sewer spills and system deficiencies and the remedial actions taken. • Adequately train and equip the Districts' sewer system operators, employees, contractors, responders, or other agents to address a sewer spill event. • Maintain and repair the Districts' sewer system to provide adequate capacity to convey base flows and peak flows while meeting or exceeding applicable regulations, laws, and generally accepted practices relative to sanitary sewer system operations and maintenance. This SSMP documents how the City and LACPWs collection system practices are integrated toward the achievement of the City's and LACPWs objectives. The City's and 14 1.3 Sewer System Management Plan Rosemead /Los Angeles County Public Works LACPW have identified the following actions to be taken under this SSMP to ensure the accomplishment of these goals: • Conduct a planned and scheduled maintenance program that will minimize the risk and occurrence of sewer spills, in support of the SSMP goals. • When sewer spills do occur, respond to the reported site in a timely manner and undertake feasible remedial actions to contain the spill to minimize impacts, including stopping the flow from reaching the storm drain, if possible. • Stop the spill as soon as possible and limit public access to the spill area to prevent public contact with any wastewater contamination. • Recover the spill to the extent feasible and return it to the sewer system and then clean up the contaminated area. • Gather and compile all pertinent information regarding the spill event, investigate as necessary to determine probable cause, document findings, report to the appropriate regulatory agencies in a timely manner, and file the completed report. SSMP Update Schedule Pursuant to the General Order, CSMD conducts program monitoring and triennial audits of its SSMP, prepares SSMP updates, and implements planned activities to achieve the City's and LACPWs collection system program objectives. Rosemead's SSMP update was prepared upon completion of the most recent SSMP Program Audit, dated April 15, 2025, and LACPWs SSMP update. The schedule for auditing and updating this SSMP is provided in Table 1-3. Element 10 of the SSMP includes a longer-term schedule for SSMP audits and updates.

These personnel, in collaboration with LACPW personnel, administer the City's sewer collection system operation, provide engineering evaluation of proposed and existing sewer facilities, administer preventive maintenance and sewer construction programs, and oversee the maintenance of sewer collection system facilities and related records and plans. Appendix A3 provides a summary of assets for all collection systems. Other relevant information regarding the City's collection systems and management program includes: • Location: Collection systems are located in Los Angeles County. • Service Area Boundary: Figure 1-1a and 1-1 b shows the geographic service area boundary in the City and Districts. • Community Served: Rosemead covers 4.69 square miles including both residential, commercial areas, industrial, recreational, agricultural, institutional, and miscellaneous. • Data Management Systems: Districts use the following data management systems. o Maximo: LACPW legacy Maintenance Management System (MMS) used for managing maintenance activities. Field crew activities are recorded in various forms such as service requests, cleaning reports, sewer maintenance daily reports, manhole adjustments, overflow report forms, etc., and are stored in the MMS. The LACPW is in the process of implementing Cityworks Maintenance Management System to schedule and track maintenance activities. o Cityworks: LACPW is implementing Cityworks Maintenance Management System to schedule and track maintenance activities. The condition assessment schedule and eventually closed-circuit television (CCN) is planned to be added to Cityworks. Cityworks will be used to record what sections have been inspected, the schedule of activities, and whether work has been completed or not. It will also be used to schedule and track fats, oils, and grease (FOG) source control inspections of industrial and commercial establishments. o HMS: LACPW utilizes the HMS database to maintain records of all sites and their locations under the FOG program. Inspectors document their findings and enter data into the HMS database, which automates the Sewer System Management Plan Rosemead /Los Angeles County Public Works inspection process and is used to track and manage permit inspection and source control data. o PowerBI: PowerBl is utilized to display spill trends and analysis, as well as city profiles, which include detailed information on manholes, pipes, pump stations, and properties. Additionally, Power BI is used to display productivity reports, detailing maintenance activities for each city. o CCN Database: Wincan and GraniteNet are used to document inspection events, inspection observations and associated videos. These systems serve as the repository for historical CCTV inspection data. LACPW is in the process of linking GraniteNet with Cityworks to maintain CCTV records. o CADD: As -built plans of the Districts' facilities are maintained by LACPW for unincorporated Los Angeles County areas and by each city within the CSMD for their own jurisdiction, with LACPW maintaining a copy for maintenance operations. Data gathered from the plans, such as system locations and alignment, pipe material, size, etc., are stored in the SMD's Computer -Aided Design and Drafting (CADD) System and Geographical Information System (GIS). o GIS: LACPW utilizes GIS to generate a mapping system that includes sewer features and map base layers such as aerial images, streets, parcels, and storm drain systems also available from other Divisions within LACPW, County Departments and other governmental agencies. SCADA: Supervisory Control and Data Acquisition system used to collect and store pump station alarm and instrumentation data. Microsoft Office: Various collection system programs are managed using Microsoft Office applications as an electronic database. Currently, Office is used to store the schedule for FOG program activities, but this will eventually be performed using Cityworks. Lateral Ownership and Operational Responsibilities: LACPW and the City do not own any portion of the service lateral. Private service laterals are the responsibility of the property owner and must be maintained by the property owner. Operation and maintenance of the local main sewer lines are the responsibility of LACPW. Regional trunk sewer lines are the responsibility of the publicly owned treatment works, such as the Los Angeles County Sanitation Districts (LACSD), for operation and maintenance. • Breakdown of Service Connections: Rosemead's breakdown of services connections is roughly 92 percent residential, 6 percent commercial, and 2 percent of other mix use. • Unique Service Boundary Conditions and Challenges: The service area faces issues with conflicts involving local lines and jurisdictional determinations between agencies like the LACSD and the City of Los Angeles, impacting operations and maintenance. 19 Q R 2 cu d L a a) L d E d In 0 w d rn LL V 0-0 g « d R aU i p ^rte m o may: E $ 8 5 cmc c y c� �Sdu�LLOS .:1 u J e • o iy a' Q R 2 cu d L a a) L d E d In 0 w d rn LL E m to $ i Cl) S ( LL ! ;.0 ! i ./ ƒ ƒ} r ) $ 4!!!=!!4! | {0010§1§1I/] \) ! £ k }� !_ &� \{ \ .)

The City on August 4, 1959, granted the LACPW the consent and jurisdiction to annex portions of the City's sewer system into the CSMD. By that action, the City has entrusted the management, operation, and maintenance of its local sanitary sewer system to the CSMD. The City, however, still maintains ownership of the sewer system. The legal authorities for the specific areas stipulated in the General Order are covered in various sections of the City Municipal Codes (CIVICS). The City adopted the 2022 California Plumbing Code as amended by Los Angeles County Title 28 — Plumbing Code and The Los Angeles County Title 20 — Utilities, which regulates sanitary sewers and industrial waste in in the County as its Sanitary Sewer and Industrial Waste Ordinance. Rosemead Municipal Code— hftps:Hlibrary.municode.com/ca/rosemead/codes/code of ordinances Plumbing Code Chapter 15.12 — hftps:Hlibrary.municode.com/ca/rosemead/codes/code of ordinances?nodeld= CD ORD TIT15BUCO CH15.12PLCO 15.12.010CAPLCOAMLOANCOPLCO AD Sanitary Sewers and Industrial Waste Chapter 13.12 - httos://library.municode.com/ca/rosemead/codes/code of ordinances?nodeld= CD ORD TIT13PUSE CH13.12SEINWA The Districts were formed pursuant to Chapter 4 of the State of California Health and Safety Code (Section H4870 — 8), with the County of Los Angeles Board of Supervisors acting as their governing body. By law, the Board of Supervisors may make and enforce all rules and regulations necessary for the administration of the Districts and for the cleaning, repair, construction, rehabilitation, renewal, replacement, operation, and maintenance of collection sewers within the Districts. Consistent with the law, several ordinances have been established by the Board of Supervisors to govern all aspects of the Districts' operations. The legal authorities for the specific areas stipulated in the WDRs are covered in various sections of the Los Angeles County Plumbing Code (LACO Plumbing Code) and Chapters 20.20, 20.24, 20.26, 20.32, 20.34, 20.36, and 20.40 of the Los Angeles County Code (LACO Code) Title 20 — Utilities, some of which are discussed below. Table 3-1 and Table 3-2 summarizes these authorities and relate them to elements of the SSMP that are impacted or utilize these authorities. Specific legal authorities are described in more detail in the elements that follow. For the contracted cities that have service agreements with the Districts, the provision of services is dependent on the specific terms of the agreement. It is assumed that the legal authorities are extended to the Districts to provide services to these Cities. 23 Sewer System Management Plan Rosemead /Los Angeles County Public Works The LACO Code, LACO Plumbing Codes, standard plans, specifications, and other materials cited in this Section are filed at the office of the Director of Public Works and can be found online in the links below: • Los Angeles County Code (hftos:Hlibrary.municode.com/callos angeles county/codes/code of ordinances) • Los Angeles County Plumbing Code htt�s://Iibrary.municode.com/caAos angeles county/codes/code of ordinances? nodeld=TIT28PLC0) Table 3-1: Summary of Legal Authorities Relating Legal Authority Element of General Order Prevent illicit discharges into the wastewater LACO 20.24.020 –Applicability of Division 2 provisions collection system LACO 20.24.200 – Notification of uncontrolled discharges required LACO 20.32.080 – Excessive discharge of sewage – Conditional permit requirements LACO 20.32.650 – Dumping of effluent - Conditions LACO 20.36.010 – Discharge of offensive or damaging substances prohibited LACO 20.36.400 – Deposit of certain substances prohibited CPC 714.1 – Unlawful Practices CPC 714.2 – Prohibited Water Discharge Collaborate with storm sewer agencies to The City is part of Consolidated Sewer Maintenance District, coordinate emergency spill responses, which is managed by LACPW.

The illegal dumping of offensive or damaging substances such as chemicals and debris, which are considered inflows, is prohibited by LACO Code, Section 20.36.010. 3.2.1 Prevention of Illicit Discharge of FOG Section 20.36.400 of the LACO Code prohibits the discharge of Fats, Oils, and Grease and other substances that may, among other things, clog, obstruct, fill, or necessitate frequent repairs, cleaning out, or flushing of sewer facilities in the sewer system. 3.2.2 Prevention of Illicit Discharge of Infiltration/Inflow LACPW have an Inflow/Infiltration (1/1) control program as part of their ongoing sewer line cleaning and maintenance program, which includes closed-circuit television and other mechanisms to detect 1/1. By ordinance, the Board of Supervisors has established a financial plan to ensure capital replacement or rehabilitation of sewer lines prone to 1/1 within the Consolidated Sewer Maintenance District (LACO Code, Section 20.40.045). The Marina Sewer Maintenance District provides adequate funding to eliminate 1/1 sources in the mainline sewers and manholes. 1 25 Sewer System Management Plan Rosemead /Los Angeles County Public Works The LACO Code, Section 20.24.080, requires property owners to maintain their house laterals, including the elimination of cracks, tree roots, and other debris. A similar requirement is found in Section 101.3.2 of the LACO Plumbing Code Title 28. 3.3 Authority to Collaborate with Storm Sewer Agencies Spills from the City collection systems flow into City storm drainage systems and Los Angeles County Flood Control drainage systems. When spills occur from collection systems in unincorporated areas, flow either goes directly into the County storm drain system or enters a local cities storm drain system, eventually discharging into the Los Angeles County Flood Control's storm drain system. Los Angeles County Public Health requires all cities in the Districts to report sewer spills that reach a drainage system within 15 minutes of knowledge of the event. As a result, Los Angeles County Flood Control is notified and can provide support to provide information and access to County drainage system facilities, if needed. The Sewer Maintenance Division, being a sister division to Stormwater Maintenance Divisions that manages the Flood Control System, allows for direct collaboration, allowing for efficient management and resolution of spills and drainage issues. With regards to preventing cross connections of sanitary sewer infrastructure to storm sewer infrastructure, cities are responsible for connections and either have their own permitting services or are under the services of the LACPWs Building and Safety Division (BSD). Unincorporated areas work directly with the BSD for permitting. 3.4 Authority to Require Proper Design and Construction of Sewers The LACO Code Sections 20.32.330 and 20.32.340 require that the design of new mainline sewers and pumping plants, respectively, be in conformity with requirements of Part 3 of Chapter 20.32 of the LACO Code. Similarly, Section 20.32.350 of the LACO Code requires that the design of new house laterals conform to the requirements of Part 3, Chapter 20.32 of the LACO Code unless otherwise covered by the LACO Plumbing Code, Title 28. The construction of a collection sewer system, by law (LACO Code 20.32.580), is required to conform to all the requirements prescribed by Division 2 of the LACO Code, by the Standard Specifications for Public Works Construction (Green Book) and by the Special Provisions and Standard Plans, all on file in the office of the Director of Public Works (County Engineer). The inspection and construction of mainline sewers and pumping plants to ensure proper construction is covered under Section 20.32.590 of the LACO Code. The construction of house laterals is covered under the LACO Plumbing Code. 3.5 Authority to Ensure Access to Publicly Owned Portion of Lateral The City and County do not own or maintain private lateral sewer lines. Property owners are responsible for proper installation, operation, and maintenance laterals (the pipe that connects from the building to the main) and clean -outs (which provide access to clean and 1 26 Sewer System Management Plan Rosemead /Los Angeles County Public Works repair the pipe from the building to the main). This includes laterals on the County -owned easement. 3.6 Limit the Authority to Discharge of FOG and other Debris The Director of Public Works under the LACO Plumbing Code, Title 28, has the legal authority to require the installation of grease interceptors at restaurants and other food establishments that generate grease. Section 20.36.560 of LACO Code also gives the Director of Public Works the authority to require the installation of treatment facilities, including grease interceptors, at any facility that generates FOG in the amount that will damage or increase the maintenance costs of the sewer collection system. The LACO Code Section 20.24.090 gives the Director of Public Works the legal authority to inspect mainline sewers, sewage pumping plants, interceptors, etc., as often as he deems necessary, to ascertain whether such facilities are maintained and operated in accordance with the provisions of Division 2 of the LACO Code. Authority to Enforce Violations of Sewer Ordinances Under Section 20.24.100 of the LACO Code, the Director of Public Works is empowered to enforce all of the requirements prescribed in Division 2 — Sanitary Sewers and Industrial Waste of the Code and in accordance with Section 20.24.110 may delegate this authority. LACO Code Section 20.24.160 allows criminal penalties for any violations of the Sewer and Industrial Waste Ordinances. 3.7 Authority to Obtain Easement Accessibility Agreements When Applicable Title 20, Division 2 of the LACO Code gives the LACPW the legal right to set requirements that allow unrestricted maintenance access to the public sewer infrastructure. This access is secured through the LACPW unwavering enforcement of the requirement for sewer easements around all public sewer appurtenances located in private properties. These easements are detailed by the designer on the sewer construction plans and are reviewed through the iterative plan check process. Plan checkers take special care to ensure that maintenance crews will have room for access and equipment usage for both routine maintenance and replacement or repair construction as necessary. Title 20 requires easements to be free of obstruction, and this is reiterated on all sewer plans that contain easements. The potential for conflict or restriction of access is reviewed exhaustively during plan check. 1 27 Sewer System Management Plan Rosemead /Los Angeles County Public Works 4 Operation and Maintenance Program 4.1 Up -to -Date Map of the Collection System LACPW gathers as -built plans and compiles into a central Document Management System, CADD System, and GIS system maintained by the Districts. For unincorporated areas, LACPW maintains the as-builts. For CSMD Cities, each city is responsible for maintaining as -built maps and the LACPW collects a copy for maintenance operations. Data gathered from the plans, such as system locations and alignment, pipe material, size, etc., are stored in LACPWs Computer -Aided Design and Drafting System and Geographical Information System. 4.1.1 Procedures for Maintaining and Providing Access to Water Boards Staff LACPW provides access to up-to-date maps of the sewer system via: Interactive GIS -maps Electronically available as-builts • Printed and electronically available Map Books GIS Maps The interactive GIS -based map of the sewer system is available online on the LACPWs website: https://dpw.lacounty.gov/smd/sewernetwork/ Within GIS, the Districts maintains a mapping system as seen in Figure 4-1 that includes sewer features such as pipe or manhole location, diameter, material, flow direction, etc. The system includes map base layers such as aerial images, streets, parcels, and storm drain systems also available from other Divisions within LACPW and other governmental agencies. The maps are regularly updated to reflect any changes in the system. Once Cityworks is implemented, valves will be included into the system map. 1 28 Sewer System Management Plan Rosemead /Los Angeles County Public Works / e UCounWY nitary5 rNe rk-ConsolidatMS tM_. mu.....u. ..wn. dn.w A 05uUoa+et�.mH. •.

When discrepancies are identified in sewer mapping, crews note them on printed map pages or through GIS on a phone and forward them to SMD GIS resources for updates. Field crews have access to both paper maps and the GIS phone application, depending on their preference. Cityworks will eventually be downloaded onto cell phones and new LACPWs tablets, allowing crews to access facility information in real-time and log operation and maintenance activities directly into the system. 1 31 Sewer System Management Plan Rosemead /Los Angeles County Public Works 4.2 Preventive Maintenance Program LACPWs maintenance services are provided from six maintenance yards strategically located within the County of Los Angeles for efficient management of maintenance activities including Spills and other emergencies. A map showing locations of the field maintenance yards and pump stations in Appendix D. The cornerstone of LACPWs maintenance operation is the Preventive Maintenance Program as described in LACPWs training guide maintained in each of the field maintenance yards. This program consists of regular inspection of the sewer system including manholes, pipes, siphons, pump stations, treatment plants, regular cleaning, repair, and related activities. This program is designed and carried out to detect and correct potential problems before they develop into major problems. The Preventative Maintenance Program is implemented through the following key activities: • CCN Inspection • Sewer Line and Manhole Visual Inspection • Gas Trap Manholes and Siphons • Drop Manholes • Sewer Line Cleaning • Root Foaming • Periodic Maintenance • Vermin and Odor Control • Sewage Pump Stations The Preventive Maintenance Program utilizes LACPWs Sewer Maintenance Division Maintenance and Operations Manual, which describes these activities in detail. This manual is available on the SMD's webpage: • hftps://dpw.lacounty.gov/sewer/maintenanceandol)erationmanual.pdf For each activity, the tasks and their frequency are determined periodically, while others are determined based on inspection findings and yard determinations. The descriptions of inspection and maintenance activities and the frequencies for each activity are detailed below. 4.2.1 CCTV Inspection Closed-circuit television (CCN) inspections of sewer pipes are conducted to investigate and diagnose issues. Factors such as maintenance history, past overflow records, sewer line locations, and age are used to determine which pipes will be televised. Additionally, LACPW implements CCN inspections at a programmatic level through the Condition Assessment Program. This program aims to perform CCN inspections and structurally rate approximately 500 miles of sewer infrastructure each year. Inspections are prioritized based on the number of spills per 100 miles for each jurisdiction. 1 32 Sewer System Management Plan Rosemead /Los Angeles County Public Works 4.2.2 Sewer Line and Manhole Visual Inspection The interior and exterior of manholes are inspected twice a year for any structural defects, sewage flow condition, presence of vermin or rodents, deleterious industrial waste, odors, and any signs of unusual settlement around or evidence of debris within the manholes and along sewer alignments. 4.2.3 Gas Trap Manholes and Siphons In the south area, gas traps are inspected and cleared of any stoppages or flow restrictions every 6 months. In other parts of the County, they are inspected and cleared of any blockages on a monthly basis. Siphons may differ in timeframe depending on the type of lines but are generally performed monthly. 4.2.4 Drop Manholes These facilities are inspected and cleared of stoppages and flow restrictions on a variable frequency and are dependent on prior inspection. The inspection cycle of the drop manholes aligns with the manhole inspection cycle in Section 4.2.2. 4.2.5 Sewer Line Cleaning Sewer lines are cleaned by hydro jet or rodding. Frequency of cleaning is based on inspection records. Sewer lines known to accumulate grease, garbage grinds, or sand are put on monthly, quarterly, or semi-annual cleaning schedule and those prone to root growth are periodically rodded or chemically treated. 4.2.6 Root Foaming Root foaming is performed on main sewer lines based on root intrusion and need, usually associated with overflowing. The frequency of root foaming is initially 1 year, then increases to an 18 -to -24 -month frequency. 4.2.7 Periodic Maintenance Periodic Maintenance (PMs) are sites that require higher -frequency cleanings due to maintenance issues. These "hot spots" are identified in the field during maintenance and inspections of sewer facilities and are often caused by debris, root intrusion, or other factors. Segments that experience spills are also added under periodic maintenance. 4.2.8 Vermin and Odor Control When evidence of infestations is observed during an inspection or a service request or complaint is received, sewers and structures are dusted or baited. Sewers infested by insects are chemically treated. 33 Sewer System Management Plan Rosemead /Los Angeles County Public Works 4.2.9 Treatment Plants and Pumping Stations The majority of the LACPWs pump stations are equipped with SCADA/alarm systems and are inspected at least once a week. Pumps and motors are lubricated, control mechanisms and valves are checked and adjusted as necessary, and equipment is repaired or modified as required. Treatment Plants are inspected daily to comply with permit -required sampling and testing and perform routine maintenance. The equipment is cleaned and calibrated, and mechanical components and process units are checked. 4.3 Scheduling and Data Collection Historically, LACPW generated and tracked work orders using the Maximo Maintenance Management System. The LACPW is in the process of implementing Cityworks Maintenance Management System to schedule and track maintenance activities. The activities the field crew performs are recorded in various forms such as service requests, cleaning reports, sewer maintenance daily reports, manhole adjustments, overflow report forms, etc., and are stored in the maintenance management system. All the asset inventory documenting maintenance activities and data collected are transferred over to the Cityworks Maintenance Management System to aid in the electronic filing and tracking. 4.4 Training LACPWs staff responsible for the operation and maintenance of the sewer collection system attend formalized training classes or seminars provided by agencies such as California Occupational Safety and Health Administration (CALOSHA), California Water Environment Association (CWEA), and International Brotherhood of Electrical Workers (IBEW). Through this training, staff are well -versed in the latest industry, the best practices for safely and efficiently performing their tasks. Training is required for new staff and when new procedures are introduced. LACPW also utilizes informal training approaches, including tailgate meetings, monthly safety meetings, and apprenticeship training programs led by higher-level staff. New Legally Responsible Officials and staff responsible for submitting data are informally instructed by an internal reporting expert. Additionally, only companies with well-trained and experienced staff are considered for either emergency spill mitigation or sewer construction and rehabilitation work. The Sewer Operations Superintendents manage field operations and maintenance activities and are responsible for making sure all collection system field employees receive training in emergency response, spill investigation, and spill reporting duties. LACPW maintains records for all SERP-related training. The date, content, trainers, and attendees are recorded for all scheduled training courses. 1 34 4.5 Sewer System Management Plan Rosemead /Los Angeles County Public Works With regards to spill response training and spill volume estimation training, the field crews operate a large system with enough spill events to provide opportunities for senior crew members to provide live -drill training for new and less experienced staff. When these events occur, new crew members are invited to observe until they can perform activities on their own. This on-the-job training involves shadowing experienced crew members and learning directly on site, rather than through drills. To estimate spill volume, the LACPW uses three methods most regularly: eyeball, measure volume, duration and flowrate. The District Staff preparing the estimate employ the method most appropriate to the sewer spill in question and use the best information available. Table 4-1: Summary of Training Program Review of General Order Requirements performed throughout the year in morning briefings at each yard. Staff are trained in the field during live spill events. Staff being trained observe trained crew members perform activities to learn and then perfonn the activities under supervision to check the training was received. New Data Submitters are trained by experienced in-house Data Submitters. Staff also attend industry provided training by CWEA and CASA and utilize training videos from the State Water Board website. Equipment Inventory Monthly — One element discussed each month. Performed as -needed or at least once annually. Performed as -needed or at least once annually. The maintenance crews are equipped with standard industry technologies including radio equipped trucks for easy communication, cellular phones, heavy and light construction equipment, vacuum trucks, pumps, generators, trucks equipped with closed-circuit television units for interior inspection of sewer lines, and various types of safety equipment. Equipment is regularly checked, adjusted, repaired, or replaced as necessary. However, major fixed assets are replaced when they meet or exceed LACPW established fixed assets replacement criteria based on the age of the equipment, mileage, hours of use, repair history, etc. Equipment categorized as Class 9 (less than 1/4 ton) or lower is automatically replaced by the Fleet Management Group when it meets the replacement criteria. The request to replace equipment higher than Class 9 is made as part of LACPW annual budget. In addition to the above replacement criteria, an analysis and recommendation by trained staff of LACPW and approval by LACPWs administration is required to replace equipment higher than Class 9. 1 35 Table 4-2: List of Major Equipment Inspection Rodder Vacuum Compressor Jetter Pickup utility Pump Masonry Dump Construction Sedan Van/Passenger Crane 2Axle Stake Tractor TOTAL Sewer System Management Plan Rosemead /Los Angeles County Public Works 22 12 7 2 10 25 4 6 4 4 2 1 2 2 3 5 2 113 These criteria, notwithstanding, a piece of equipment can also be replaced if its reliability or safety of operation becomes questionable. New and additional equipment is also acquired when fully justified based on increased workload, new activity, additional personnel, technological improvements, time and cost savings, employee or public safety requirements, etc. Each Collection System Yard maintains the spare equipment and parts needed by that yard to maintain the sewer pipelines and pump stations within the yard's service area and each is responsible for ordering replacements. 1 36 Sewer System Management Plan Rosemead /Los Angeles County Public Works 5 Design and Performance Provisions 5.1 Design and Construction Standards and Specifications The City requires that all sewers be designed in accordance with LACPWs standards. The LACPW has standard plans and specifications for the construction of sanitary sewers and appurtenances to ensure that sewer lines and connections are properly designed and constructed. The LACPW specifications by reference incorporate the: • Standard Plans for Public Works Construction; • Standard Specifications for Public Works Construction ("Green Book"); • Standard Plans Public Works 2000 Edition; • Special Provisions; and • Standard Drawings. In addition, LACPW has other publications such as the Private Contract Sanitary Sewer Procedural Manual, Guidelines for the Design of Pump Stations, etc., to maintain consistency in the design of collection systems within the unincorporated County areas and CSMD member cities. The City requires that these publications also be followed in the design of sewer systems within the City. To further ensure that sewer facilities are properly designed, the City requires construction drawings to be prepared by licensed engineers. The construction drawings are thoroughly reviewed by the City and SMDs engineers prior to approval for construction and inspection of the actual construction work. SMD review plans to ensure that appropriate maintenance standards are integrated into the design from a maintenance standpoint only. 5.2 Procedures and Standards for Inspecting and Testing System Improvements To further assure that sewer facilities are properly designed and constructed, the LACPW requires that sanitary sewer plans are designed by licensed engineers and provides thorough review of plans prior to approval for and conducting inspection of construction work. Each city within CSMD has its own design and construction standards and requirements. Prior to accepting a newly completed sewer system for maintenance, each city is responsible for assuring sewers are designed and constructed to standard. The following procedures are used to ensure compliance with LACPW standards for portions of the system designed and constructed in unincorporated areas: The following procedures are used to ensure compliance with LACPW standards for portions of the system designed and constructed within the City: The City provides inspection by outsourcing to qualified consultants for the inspection of new sewer construction projects. The City requires that as -built plans of the completed projects be submitted prior to final approval for acceptance of sewer facilities for public use. 1 37 Sewer System Management Plan Rosemead /Los Angeles County Public Works • Within the City new sewers, as well as sewer lines rehabilitated by lining, be televised and the video reviewed by SMD's personnel prior to the acceptance of the completed project. In compliance with LACPW's policy, the City requires that all new or rehabilitated pumping stations be inspected by experienced SMD Electro -Mechanics prior to acceptance for maintenance by the SMD. • LACPWs inspectors are well trained in pipeline and pump station construction. They attend training classes and educational seminars to stay familiar with advancements in the industry. The inspectors are also provided with adequate materials to perform their jobs, including the Standard Specification for Public Works Construction Inspection Manual, the Green Book, etc. 1 38 Sewer System Management Plan Rosemead /Los Angeles County Public Works 6 Spill Emergency Response Plan The LACPW's Spill Emergency Response Plan (SERP), included in Appendix F provides guidelines for LACPW's maintenance crew to follow in responding to, cleaning up, and reporting sewer spills that may occur within the Districts' service area. The purpose of the SERP is to support an orderly and effective response to sewer spills that ensure all regulatory requirements are met. The LACPWs SERP comprehensively addresses notification, response, assessment, and recordkeeping requirements of the SWCRB General Order as summarized in Table 6-1. Table 6-1: Spill Emergency Response Plan General Order Compliance Wk r' 1111111110imw,,- -1arl�crrarrls Notify primary responders, appropriate local officials, and appropriate regulatory 2, 3.4 agencies of a spill in a timely manner; Notify other potentially affected entities (for example, health agencies, water 2, 3.4, 3.7 suppliers, etc.) of spills that potentially affect public health or reach waters of the State; Comply with the notification, monitoring and reporting requirements of this 4 General Order, State law and regulations, and applicable Regional Water Board Orders; Ensure that appropriate staff and contractors implement the Spill Emergency 6 Response Plan and are appropriately trained; Address emergency system operations, traffic control and other necessary 3 response activities; Contain a spill and prevent/minimize discharge to waters of the State or any 3.4 drainage conveyance system; Minimize and remediate public health impacts and adverse impacts on beneficial 3.4, 3.6 uses of waters of the State; Remove sewage from the drainage conveyance system; 3.6 Clean the spill area and drainage conveyance system in a manner that does not 3.6 inadvertently impact beneficial uses in the receiving waters; Implement technologies, practices, equipment, and interagency coordination to 3.6 expedite spill containment and recovery, Implement pre -planned coordination and collaboration with storm drain agencies - and other utility agencies/departments prior, during, and after a spill event; Conduct post -spill assessments of spill response activities; 3.8, 4.5 Document and report spill events as required in this General Order; and 4 Annually, review and assess effectiveness of the Spill Emergency Response 6.1 Plan, and update the Plan as needed. 6.1.1 Pre -Planned Coordination with Other Agencies or Departments Member cities hold periodic meetings to review roles and responsibilities. For example, the role of the City is to support securing the site and initial containment before SMD field crews arrive. When appropriate, LACPW invites LACSD staff to discuss any jurisdictional inquiries or investigations of spills. 1 39 Sewer System Management Plan Rosemead /Los Angeles County Public Works 7 Sewer Pipe Blockage Control Program 7.1 Program Overview Analysis of sanitary sewer overflows over the last 3 years indicates an average of 88 percent of spills within the Districts collection system is linked to roots, debris, grease, pipe structural failure, and pump station failure either as a primary or secondary cause factor. Between 2021 and 2024, an average of 30 percent of spills were linked to grease accumulation and 18 percent linked to debris accumulation. To prevent the build-up of Fats, Oils, and Grease (FOG) that can cause blockages and restrictions in flow, the County has implemented a FOG program to prevent sewage overflows into the environment, as well as to reduce the discharge of FOG to the sewer system. Rosemead experienced 4 sewer overflows between 2001 through 2024, all spills caused by FOG. The Environmental Programs Division (EPD) is responsible for performing fats, oils, and grease source control inspections of food service establishments (FSEs). The EPD regulates industrial waste disposal for 36 cities by contract and all unincorporated areas. The number of FSEs per City and within the unincorporated areas are listed in Table 7-1. 40 Sewer System Management Plan Rosemead /Los Angeles County Public Works Table 7-1: Number of FSEs per City/Area Unincorporated Area 1025 Lakewood 181 Artesia 118 Cerritos 144 Paramount 52 Bellflower 51 La Mirada 74 Hawaiian Gardens 21 Carson 169 Culver City 188 Rolling Hills Estate 20 Lawndale 46 Cudahy 12 Lomita 58 Rosemead 114 Duarte 53 Irwindale 39 Temple City 55 Commerce 102 Bell Gardens 91 La Canada Flintridge 49 Beverly Hills 135 San Fernando 52 Westlake Village 50 Agoura Hills 65 West Hollywood 255 Calabasas 53 San Dimas 80 Walnut 52 Diamond Bar 75 Santa Clarita 376 Total 1324 1 41 Sewer System Management Plan Rosemead /Los Angeles County Public Works A list of cities that EPD supports with industrial waste disposal, including FOG source control inspections, can also be found on the Los Angeles County official website: hftps://cleanla.lacounty.gov/industrial-waste/#Jurisdictions For the other Cities that are not on this list, the City handles all their own FOG -related source control activities. The EPD's FOG program guidelines and procedures can be found on the Industrial Waste page on the LACPW's website: httos:Rclean la.lacounty.aov/industrial-wastet#Obtaini na-Clearance The website provides FOG guidelines, standard drawings for grease pretreatment devices, permit forms, and details on EPD's FOG program. 7.2 Implementation Plan and Schedule for Public Outreach 7.2.1 Summary of Outreach Activities The LACPW conducts public outreach through various channels to educate the community about Fats, Oils, and Grease management: Community Events: LACPW participates in resource fairs, park events, and Earth Day- themed events, where staff distribute FOG brochures and answer questions from the community. • Website Resources: The FOG page on LACPW's website provides a comprehensive list of FOG do's and don'ts: hfti)s://Pw.lacounty.gov/SMD/�grease/Index.cfm • Inspections: During inspections of FSEs, FOG inspectors provide educational materials on best management practices (BMPs) for grease traps and interceptors. Newly permitted FSEs also receive BMP materials. By engaging with the community and FSEs through these activities, LACPW aims to promote effective FOG management practices and prevent blockages in the sewer system. To complement LACPW efforts, the City will initiate its own Public Education Outreach Program. This will consist of including SSO- and FOG -related articles from the LACPW and other sources, such as the City's newsletters and webpage (https://www.citvofrosemead.or-q), and by maintaining continuous communication with the LACPW, City residents, and other stakeholders on these and other issues. City personnel also disseminate information to residents during meetings or while conducting right-of-way lateral work inspections. 7.2.2 Plan and Schedule of Events The schedule of outreach activities is based on opportunities for public engagement and the frequency of FSE inspections. When an opportunity arises for SMD to participate in a public event, the Community and Government Relations Group (CGRG) notify them. Many of these events occur annually and SMD tries to be involved if notified by the CGRG in Sewer System Management Plan Rosemead /Los Angeles County Public Works time to coordinate. CGRG keeps track of all the events the LACPW participates in annually, providing a summary of events at the end of the year. FSE Outreach is timed around FSE inspections. FSE owners are provided with educational material when FOG inspectors visit to inspect grease traps and interceptors and check for any violations. 7.3 Plan and Schedule for Disposal of FOG For the disposal of grease and other pipe -blocking substances, FSE's must obtain an Industrial Waste Disposal Permit from EPD that requires a schedule of frequent maintenance and documentation of maintenance and disposal of waste. Under the permit, grease traps are required to be maintained/pumped daily while grease traps/interceptors that can handle 750 gallons or greater require quarterly maintenance. FOG haulers have multiple options for grease disposal, including Baker Commodity in Vernon and designated disposal locations in Los Angeles and the County Sanitation Districts of Los Angeles County. These disposal sites are regulated and require a fee. The solidified fats found in the City and LACPW collection system during cleaning operations are trapped, collected, and taken to the maintenance yard dump bins. Once the bins are full, these and other debris collected from the system are taken to the County Sanitation Districts of Los Angeles County facilities. 7.4 Authority to Prohibit FOG Discharges and Identify Measures to Prevent FOG Spills 7.4.1 Authority The City and LACPW legal authority to prevent illicit discharges into the sanitary sewer system and to limit the discharge of FOG and other debris that may cause blockages in the sewer lines is discussed in Chapter 3. 7.4.2 Preventative Measures The LACPW utilize semiannual manhole inspection of all manholes and the scheduled and unscheduled sewer line cleaning and television inspection of the interior of sewer pipes to identify pipe segments experiencing heavy grease accumulation and in mitigating the problem. These legal mandates and maintenance practices are complemented by the LACPW's Public Education and Outreach Program discussed in Section 7.1 to minimize Spills and blockages caused by FOG. 7.5 FOG Program Requirements and Design Standards A pretreatment system/device is required for any new and existing food service establishment or similar facility where FOG from food preparation is discharged into the sewer system in quantities that may cause blockages or interfere with sewage treatment or disposal. All pretreatment facilities, whether required by EPD or installed voluntarily, shall be maintained and operated under a valid Industrial Waste Disposal Permit (IWDP) for the operating life of the facility. 1 43 Sewer System Management Plan Rosemead /Los Angeles County Public Works FOG program requirements are outlined in the IDWP Conditions and Limitations (Appendix G1) and are supported by the Pretreatment Guidelines For Restaurants And Food Service Operations. 7.5.1 Requirements to Install Grease Removal Devices The LACPWs legal authorities to enforce the requirements stipulated in this section are discussed in Chapter 3. The Director of Public Works has enforcement authority for industrial waste permitting per Section 20.36.040 of the LACO Code and charged the EPD with permitting and inspecting more than 1,300 food service establishments that discharge into the sanitary sewer system in the unincorporated areas and 36 contract cities within the CSMD. New or remodeled FSEs and those under new ownership must also secure a permit from the Building and Safety Division (BSD). If there is a FOG- related problem associated with an industrial waste permit, DPW will take enforcement action against the permittee, or where applicable, refer the problem to the contract city for enforcement action. The EPD requires that industrial waste generating facilities and any FSE with the potential to produce grease install a grease control device (GRD). The LACPW does not issue permits or inspect domestic sewage disposal to the sanitary sewer system. However, the LACO Code prohibits the discharge of "any material, which may create a public nuisance, or menace to the public health or safety, or which may pollute underground or surface waters, or which may cause damage to any storm drain channel or public or private property" (Section 20.36.010). If during inspection of the sanitary sewer system LACPWs personnel determine that a FOG -related problem exists and is traceable to a domestic sewage source of such character that is not satisfactory, under the LACO Code (section 20.20.100), pretreatment could be required or the discharge required to be eliminated. Domestic waste containing FOG can lead to spills, which are public nuisances and is a violation of California Health and Safety Code Division 5, Part 3, Chapter 6, Article 2, which can also be used to impose appropriate domestic sewage discharge requirements. 7.5.2 Design Standards for Grease Removal Devices FSEs are required to size, design and construct grease traps and interceptors according to the LACO Plumbing Code. Additionally, they are required to be approved, installed, and operated in a manner to control discharges of FOG into the sanitary sewer system and to ensure that the facilities do not create nuisances, menaces to the public peace, health or safety hazards, or adverse impacts to the public sewer system, soil, underground, and/or surface waters. The Industrial Waste online page on the County's website provides standard drawings for grease pretreatment devices: httos://cleanla.lacounty.00v/industrial-waste/#Obtaining- Clearance 7.5.3 Maintenance Requirements The IWDP Conditions and Limitations have a minimum maintenance frequency condition and a requirement to maintain the GRD in proper working order. During inspections, inspectors physically examine the GRD. If a grease interceptor (GI) is used, FSEs are I" Sewer System Management Plan Rosemead /Los Angeles County Public Works required to open and inspect it. If issues are identified, they are documented, and a job order is created. The FSE signs off on the order and receives a receipt. If cleaning records are not provided, or if the GI cannot be accessed, the FSE must clean it. Permit conditions require: GIs to be cleaned at least once every three months FSEs with grease traps are required to perform daily maintenance 7.5.4 Best Management Practices Requirements 7.5.5 The Pretreatment Guidelines for Restaurants and Food Service Operations provide guidelines and best management practices for selecting and installing pretreatment devices. These guidelines outline the installation requirements for grease interceptors and offer a list of alternative pretreatment devices that can be used in lieu of a grease interceptor. During inspections, inspectors verify whether best management practices are being followed, such as maintaining proper documentation, using adequate devices, and employing appropriate disposal methods. In incorporated areas, inspectors distribute flyers outlining the dos and don'ts of fog management and request that these flyers be displayed at workstations for workers to see. 7.5.6 Record Keeping and Reporting Requirements As a condition of the Industrial Waste Permit, FSEs must record the maintenance of grease trap/interceptors on a maintenance log report. The log records date of the service performed, types of services performed, and person/company providing service. Additionally, for any liquid or solid industrial wastes transported from the site, FSEs must obtain and keep copies of receipts for grease trap/interceptor maintenance and pumping for at least 180 days. The maintenance log report and receipts shall be made available to LACPW and the City (if applicable) upon request. 7.5.7 Procedures The LACPW implements the following procedure to identify and manage sections of the system impacted by FOG blockages: Identification: Sections impacted by FOG blockages are identified through regular inspections conducted by cleaning crews, CCTV inspections, and reports of spills. • Investigation: Once identified, these sections are thoroughly investigated to assess the extent of the blockages and determine the appropriate actions needed to address them. • Maintenance: Based on the investigation findings, a periodic cleaning schedule is defined and implemented for each affected section to ensure ongoing maintenance and prevent future blockages. Sewer System Management Plan Rosemead /Los Angeles County Public Works 7.6 Inspection and Enforcement Program 7.6.1 Authority to Inspect Grease Producing Facilities As discussed in Chapter 3 of this document, Section 20.36.400 of the LACO Code provides legal authority to inspect FOG -producing facilities, prohibiting the discharge of substances that may obstruct or require frequent maintenance of the sewer system. The source control inspection process follows standard workflow, including researching plans, preparing for the inspection, reviewing operations, and requesting GRD maintenance documentation. Inspectors may ask questions about waste oil management, changes in operations that affect the permit, and maintenance frequency. They also check for compliance with Best Management Practices such as ensuring BMP posters are visible in the kitchen. Inspectors document their findings and enter data into the HMS database. When SMD encounters FOG issues in the collection system, whether from spills CCN inspections, or sewer cleaning, the source of the problem is evaluated as either residential, commercial, or both. For residential spills, SMD may notify residents door-to-door, providing information on proper grease disposal practices. For recurring issues, the affected area is placed on a preventive maintenance schedule. In the case of commercial spills, the incident is referred to EPD for investigation. EPD checks GRD maintenance and requires corrective actions when needed. If an FSE without a GRD is responsible for a spill, EPD mandates the installation of a GRD. If a GRD -equipped FSE causes a spill, more frequent maintenance may be required. All investigations are documented in the HMS database, and results are communicated to SMD as relevant. 7.6.2 Authority to Enforce The enforcement process for violations varies based on location. In unincorporated areas, inspectors issue a Notice of Violation or Order to Comply with a set deadline. Follow-up inspections verify compliance, and unresolved issues may be escalated to supervisors. In rare instances, compliance issues are referred to headquarters, possibly resulting in legal action with the District Attorney. In CSMD cities, violations are handled similarly, but escalation may involve the City's Code Enforcement and, if necessary, the City Attorney. 7.6.3 Resource Plan to Inspect and Enforce The EPD has sufficient inspection and enforcement staffing to achieve an annual FSE inspection cycle and follow up on requirements and violations identified. LACPWs current funding allows for increases in permit and other services charges if necessary to hire additional staff. 46 Sewer System Management Plan Rosemead /Los Angeles County Public Works 7.7 Maintenance Program to Address FOG Issues As described in Section 4, FOG prone sections of LACPWs collection system, referred to as "hot spots," are identified during routine maintenance operations and investigation of stoppages and spills. These portions of the system found to have persistent FOG problems are put on monthly, quarterly, or semi-annual periodic cleaning schedule, depending on the magnitude of the problem. Furthermore, segments of the collection system with persistent FOG problems are referred to the EPD for additional investigation and enforcement actions. 7.8 Implementation of Source Control Measures to Address FOG Issues 7.8.1 Summary of Source Control Measures Pretreatment devices are used to remove grease from sewage to prevent the accumulation of FOG that can lead to blockages. LACPW provides pretreatment guidelines to FSEs, offering guidance on how to adequately select, size, and install a pretreatment device based on the amount of grease produced. The maintenance of these devices is outlined in the IWDP to ensure proper operation and functionality. Under the IWDP, LACPW or City may require upgrades to grease interceptors if maintenance is inadequate or if the interceptor is too small to handle the waste stream. 7.8.2 Summary of Source Control Program Enforcement The EPD conducts routine inspections of FSEs and inspects new establishments. Investigations are also performed when spills occur. When SMD receives complaints and determines that FOG may have caused a spill or has the potential to cause a spill (e.g., grease accumulation), they reach out to the EPD for further investigation. Upon investigation, the EPD may make adjustments to the permit and treatment requirements to prevent such incidents and/or place the impacted area under periodic maintenance as described in Section 4.2.7. Under the Industrial Waste Discharge Permit (IWDP), LACPW or City may modify the permit and its conditions and limitations as necessary to ensure proper waste disposal. 47 Sewer System Management Plan Rosemead /Los Angeles County Public Works 8 System Evaluation, Capacity Assurance and Capital Improvements The LACPW has implemented procedures for system evaluation, capacity assurance, investment prioritization, and capital improvement planning. This section documents the procedures and activities for: • Routine evaluation and assessment of system conditions; • Capacity assessment and design criteria; • Prioritization of corrective actions; and • Capital improvement planning. 8.1 System Evaluation and Condition Assessment 8.1.1 Best Practices and New Technology LACPW uses CCTV as the primary tool for condition assessment of pipelines which is in accordance with industry standards for small diameter pipelines. Use of CCN is the industry best practice for sewer pipeline condition assessment given the pipe size range (6 -inch to 36 -inch) the County owns and operates. 8.1.2 Amount of System Condition Assessment Under the Condition Assessment Program (CAP), SMD plans to perform CCN inspections at a rate of approximately 500 miles of sewer infrastructure each year starting in 2025. The complete cycle is scheduled to last a total of approximately 10 years, with the period between inspections dependent upon age and results from the last inspection. Newer pipe segments found to be in good condition in the prior inspection will have a low priority in the next inspection cycle. SMD inspects all manholes twice a year. 8.1.3 Inspection and Condition Assessment Prioritization Historically, LACPWs CAP prioritized condition assessment projects based on jurisdiction/cities with ordering based on spill rate. The assessment prioritized sewer lines with the most potential for repair needs based on maintenance history, past overflow records, sewer line locations, and age. Based on the reissued General Order LACPW will incorporate additional factors into condition assessment prioritization. These include areas that: • Hold a high level of environmental consequences if vulnerable to collapse, failure, blockage, capacity issues, or other system deficiencies; • Are located in or within the vicinity of surface waters, steep terrain, high groundwater elevations, and environmentally sensitive areas; • Are within the vicinity of receiving water with a bacterial -related impairment on the most current Clean Water Act section 303(d) List; 1 48 Sewer System Management Plan Rosemead /Los Angeles County Public Works The LACPW plans to develop and implement an approach to incorporate these factors into condition assessment prioritization by May 2027. 8.1.4 Inspection Methods The LACPW uses CCTV inspection as the primary means for collecting visual observations of system conditions. This CCTV inspection program digitally records the condition of the pipe interior from manhole to manhole using a robotic camera tethered to a camera van. While the video is being captured, a National Association of Sewer Service Companies (NASSCO) Pipeline Assessment and Certification Program (PACP) certified crew member views and logs events such as defects and observations using the standardized NASSCO PACP observation codes. With GraniteNet, the digital video inspections files are transferred via cloud enabling access to anyone with credentials and password access using a laptop or mobile device. In addition to CCN inspection, visual inspection is conducted on sewer facilities during sewer system maintenance activities. In the past, a field crew would document visual observations and system issues on a form to trigger follow up inspections and repair actions. Once the Cityworks is implemented, field crews can provide these observations electronically using mobile devices for immediate communication to SMD Superintendents and Supervisors to trigger follow-on actions to address issues. 8.1.5 Utilizing Observations for Condition Assessment The LACPW utilizes the NASSCO rating system to identify defects and observations using PACP observation codes. The City plans to continue using the NASSCO PACP condition rating for sewer pipelines and is planning to incorporate the MACP for manhole condition assessments. The LACPW prioritizes repairs of critical structural defects. These include NASSCO PACP Structural Grade 5 defects with potential for soil migration and undermining of pipe bedding leading to pipe movement and having potential for accelerated deterioration (i.e., pipe collapse, broken void visible, broken soil visible, hole void visible, hole soil visible, missing wall, and severe offsets impeding flow). These types of defects also have potential for leakage. Other less severe NASSCO PACP Structural Grade 5 and NASSCO PACP Structural Grade 4 defects are not prone to leakage due to collimation and sealing of the defects with sedimentation and biological growth. Throughout Los Angeles County, historical rivers and creeks have been concrete -lined or replaced with storm drainage piping. LACPW is not aware of any locations in the CSMD service area where there is potential for subsurface leakage reaching water of the State. The LACPW also performs visual inspections weekly at pump stations to verify the pumps are performing well, are properly maintained, and are in compliance with standards. If issues are identified, they are addressed via a corrective maintenance work order or elevated to be included in a project. 8.1.6 Inspection and Assessment Recordkeeping The LACPW documents and recordkeeping of system evaluation and condition assessment inspections and activities have historically been maintained using WinCan 1 49 Sewer System Management Plan Rosemead /Los Angeles County Public Worcs software with videos stored on LACPW servers. LACPW recently transitioned to using GraniteNet, a cloud -based CCN software, which will enable access to CCTV data and videos to anyone with password access and credentials from mobile devices or laptops connected to the internet. In the past, when field crews conduct visual inspections during maintenance activities, system deficiencies requiring action were recorded as footnotes on forms for replacements, repairs, and issue identification. Once the Cityworks is implemented, field crews can use mobile devices to document these issues in the Cityworks Maintenance Management System to better manage and keep record of findings and address issues. 8.1.7 Assessing Assets Vulnerable to Climate Change The District's service area has sections of the system that are susceptible to climate change impacts from flooding, landslides, wildfires, and power disruptions that may cause service disruptions. LACPW plans to develop and implement procedures to identify and address system assets vulnerable to direct and indirect impacts of climate change by November 2027, including but not limited to: • Sea level rise • Flooding and/or erosion due to increased storm volumes, frequency, and/or intensity • Wildfires • Increased power disruptions LACPW has an overarching Emergency Response Plan for addressing large-scale emergency events. These procedures provide comprehensive guidelines for personnel to effectively respond to various emergency situations including communication directives, preparatory assignments, and specific actions for different types of emergencies. Specific Emergency Procedures related to climate change include: • Earthquake Response Procedures • Fire Response Procedures • Storm Response Procedures • Electrical Power and Telecommunication Outage • Tsunami (Large Wave) and High Tide Procedures • Sewage Leakage and Overflows • Air Pollution Emergency Response Procedures • Land Movement and Rockslide Response so Sewer System Management Plan Rosemead /Los Angeles County Public Works 8.2 Capacity Assessment and Design Criteria 8.2.1 Gravity Facilities The City is responsible for confirming that newly constructed pipelines are constructed with adequate hydraulic capacity. A study is required for each development to analyze the capacity of the existing system and will set forth mitigation requirements for developers to ensure adequate capacity sizing of proposed sewer lines to accommodate the current design and future base, peak, and wet weather flows. CSMD member cities are responsible for capacity assurance within their jurisdictional boundaries. A preliminary assessment determines whether a sewer area study is required, based on zoning and acreage to estimate the load. If the estimated load exceeds thresholds, a sewer area study is triggered. Sewer load calculations are lot -based, determined using parcel size and zoning type. A standard measure, such as cubic feet per second (cfs) per acre, is used, with flow rates varying by zoning type. This methodology results in sewer lines are designed to handle the specific load for each parcel. Increased densification due to new zoning or development to full capacity may necessitate resizing existing sewer pipes. For all new projects impacting the capacity of the public sewer system, the LACPW requires the submission of a sewer area study. The capacity assessment assumes an ideal system with no illegal connections and uses a design criterion of 1/2 -full pipe capacity as adequate for lines smaller than 15 -inch in diameter, and 3/4 -full pipe for lines 15 -inch and greater. Reports are submitted and reviewed through a plan check process. The sewer area study procedure and support materials for the unincorporated areas of Los Angeles County can be found on the Land Development Division website: • https://pw.lacounty.aov/ldd/Iddservices/sewerAreaStudy/sewerAreaStudy.shtml The City is responsible for ensuring that the public sewer infrastructure is correctly designed, adequately sized, and easily maintained. LACPW provides a supporting role in reviewing all proposed sewer plans for new developments in the City to ensure that they conform to LACPWs design standards and to ensure that requirements for acceptability for maintenance are met. The Director of Public Works/City Engineer or hired qualified private company provides thorough review of all sewer plans for proposed development projects in the City to ensure that (1) they are properly designed with sufficient capacity for current and future base, peak, and wet -weather flow demands; and (2) any impact of proposed project on existing sewer system is mitigated prior to being approved by the Director of Public Works/City Engineer. During construction, the projects are continuously inspected by the Director of Public Works/City Engineer or hired construction inspectors to ensure that sewer facilities are constructed in accordance with the approved plans and specifications. 8.2.2 Pressure Facilities Pump stations within the City and LACPW are designed for full buildout and include redundancy in controls and pumping systems. If developers seek to connect additional 1 51 Sewer System Management Plan Rosemead /Los Angeles County Public Works tracts, they must hire an engineer to evaluate the pump station's capacity needs. Flow studies are conducted on a case-by-case basis through the permitting process. Sewer line flow measurements are performed to assess the capacity of lines suspected of being surcharged. These measurements are straightforward for established sewer systems, though more remote systems require additional permissions for access. 8.2.3 Infiltration and Inflow The assessment of increased infiltration and inflow (1/1) is conducted in collaboration with LACSD. LACSD performs studies to identify sources of 1/1 into their system, which may include LACPWs collection systems, potentially triggering an assessment of LACPWs system. Mitigation strategies include sealing manholes and sewer lining, LACPW with LACSD providing the sealant and lining materials. Additionally, LACSD and LACPW develop a list of manholes affected by 1/1. LACSD typically requests that manholes be sealed, and peepholes corked. Sampling and analysis are performed as needed. 8.2.4 Erosive Forces in Canyons and Streams The LACPW mitigates erosive forces for pipelines crossing or near rivers and streams by requiring these pipelines to be concrete encased. The methods of encasement are defined in LACPWs Design Standards Manual. 8.2.5 Design Flow and Weather Events The system is designed according to LACPWs Design Standards to accommodate dry weather peak flow conditions and design storm and wet weather events. Approximately 91 percent of pipelines in CSMD system are 8 -inch vitrified clay pipes and approximately 8 percent are 10 -inch to 15 -inch diameter. The City has approximately 96 percent of pipes that are 8 -inch vitrified clay pipe and approximately 4 percent are 9 -inch to 18 -inch diameter. These pipelines collect flows from small sewer catchment areas and convey the flows to the nearest LACSD trunk sewers for conveyance to an LACSD treatment plant for treatment and disposal. 8.2.6 Capacity Assessment Data When performing sewer capacity studies within the City's boundary, developers can obtain reference data for the development of sewer studies and capacity assessments directly from the City. LACPWs Land Development Division (LDD) can assist upon request from the City. When performing sewer capacity studies within the unincorporated areas of Los Angeles County, developers can obtain reference data for the development of sewer studies and capacity assessments on LDD's website. The website provides guidance on the approval process, links to information such as as-builts and sewer locators, and examples of required documents. If contractors need additional information, they may reach out to LDD directly to request any additional materials. The LDD collects, maintains, and archives all sewer studies and flow data performed, and can provide this information upon request. Additionally, LDD has access to and can provide information as needed from sewer pipeline condition assessments, system 52 Sewer System Management Plan Rosemead /Los Angeles County Public Works inspections, spill history, and other available data used to assess system deficiencies and identify necessary system repairs and rehabilitation. 8.2.7 Capacity Enhancement Plan The Sewer Collection System Capacity Enhancement Program is a combined effort between the City and LACPW. LACPWs Capacity Enhancement Plan focuses on managing infiltration and inflow (1/1) by requiring proper system design through plan checks, careful inspection during construction, and the use of appropriate pipe materials. After installation, multiple strategies are employed to identify and eliminate 1/1 sources where feasible. Detection strategies include visual inspections, CCTV, and smoke and dye testing. • If the sources are due to illicit connections such as sump pumps, roof drainage, surface water diversion into a manhole, etc., applicable laws are enforced to eliminate them. • Significant structural issues like collapses, breaks, holes, or severe offsets are corrected through repair, replacement, or lining. • Maintenance issues such as grease accumulation and debris are addressed through regular sewer line cleaning, and flow measurements are used to assess the capacity of sewer lines suspected of surcharging. 8.3 Prioritization of Corrective Actions LACPW prioritizes corrective action based on: • Likelihood of failure which is determined from findings of condition assessment (e.g., prioritizing NASSCO PACP rating, 4 and 5) and; • Consequence of failure (e.g., proximity to water body, railroad, road type, and easement) Areas with multiple priority segments to factor in areas to be repaired at a time Based on the condition grading and observed defects, LACPW prioritizes sewer segments for remediation. NASSCO PACP Structural Grade 5 defects are significant structural deficiencies. Pipe segments with these defects are placed on a repair list with the highest priority focused on pipes with NASSCO PACP Structural Grade 5 defects prone to accelerated deterioration. Sewer repairs are also prioritized based on maintenance history, past overflow records, sewer line locations, and age as they contribute to the likelihood and severity of spills. 8.4 Capital Improvement Plan Responsibility for capital improvements varies based on the type of improvement required. For new sewer installations, collection systems owned by the Cities receive funding from the City. New connections and capacity -related improvements in unincorporated areas are funded and constructed by the developers, including construction contracting (refer to Section 8.2). The County provides oversight throughout the design and construction of the capacity related improvements, including review and acceptance during permitting, 1 53 ME Sewer System Management Plan Rosemead /Los Angeles County Public Works design reviews, and construction. The Design Division is responsible for developing the design criteria for CIP projects, and Project Management Division III manages the development, design and construction. The Land Development Division manages the County Improvement Projects in unincorporated areas, including tracking budget, scope, and schedule. The City manages their own CIP schedule, tracking budget, scope, design, and construction of new connections and capacity -related improvements within their boundary. For rehabilitation and repair, the Districts manage and funds projects for both City systems and unincorporated areas. The Districts focuses on lining and emergency point repairs for damaged pipes to maintain operations and reduce the risk of sewer spills. Most repairs are delivered through on-call contracts, including work on gravity mains, force mains, pump stations, and treatment plants. The Accumulative Capital Outlay Program (ACO) and special zones fund the repair and maintenance of SMD facilities. Accumulative Capital Outlay Program The Accumulative Capital Outlay (ACO) Program fund was established in 1987 as a mechanism to pay for sewer pipe replacements, relief sewer construction, and maintenance improvements to sewage pumping stations. The objectives of the fund are to establish a charge to be collected from each parcel of real property in the CSMD and utilize these monies for sewer line repair and rehabilitation projects (emergency or scheduled). Additionally, some deteriorated lines are discovered during preventive maintenance of our sewer lines. These lines are either immediately repaired by force account, using emergency contractors, or added to the list of future ACO projects. Table 8-1 lists the contracts under the ACO program as of May 5, 2025. All sewer pipe segments within the District's service areas found to have significant structural deficiencies will continue to be repaired or rehabilitated under the ACO program. Table 8-1: ACO Program Contract List Fountain Springs Pump Station 1,214,199 Sept, 2026 Sept, 2028 San Dimas Pump Station 1,214,199 January, 2026 April, 2027 On -Call As -Needed Contract 62,202,057 Est. July 2025 Est. July 2030 8.4.2 Joint Coordination and Interagency Coordination The majority of collection system improvements are managed by Sewer Maintenance Division staff using resources from on-call contracts for planning, design, and construction. In some cases, projects are managed by PMD III. In either case, coordination between operation and maintenance staff, County engineering staff, consultants and contractors 154 CJ 9.1 Sewer System Management Plan Rosemead /Los Angeles County Public Works occur throughout the planning, design and construction phases of project delivery. Project delivery incorporates coordination meetings and milestone deliverable reviews by all stakeholders. Early in the project delivery process, impacted agencies and entities are identified to initiate communication and permitting to streamline project delivery. This includes communication and coordination with CSMD Cities if the work is being performed on their collection system. Another primary impact agency is LACSD, since there are numerous connections between LACPWs collection systems and LACSD trunk sewers. LACPW also coordinates with the City of Los Angeles and Las Virgenes when necessary, when working in areas where their systems connect to LACPWs systems. Other impacted entities can include Army Corps of Engineers, Department of Fish and Wildlife, railroads, schools, neighboring cities, or CSMD member cities. Collaboration helps align project planning, and resource allocation for engineering, design, and construction. Regular communication, data sharing, and joint meetings support the coordination of timelines, permitting, and infrastructure improvements while reducing conflicts across jurisdictions. All coordination of stakeholders and community engagement is managed by LDD staff. Monitoring, Modifications Measurement and Program Maintenance of Information to Prioritize SSMP Activities Relevant information for prioritization of SSMP activities is collected in an array of information systems, databases, and spreadsheets. • WinCan and GraniteNet are used to video and log events from CCN inspection. WinCan is the legacy repository. LACPW recently implemented GraniteNet and will be using GraniteNet for all future inspections. • Historically, LACPW documented maintenance activities in the field using paper forms and work orders and later entered into Maximo. LACPW is transitioning from Maximo to Cityworks for management of maintenance activities. The implementation of Cityworks will streamline data collection and improve asset management efficiency. FOG inspection activities are recorded on paper and stored in the HMS database. • Spill data is stored in the State Water Resources Control Board's CIWQS database and SMD internal PowerBl database. Productivity reports documenting and summarizing the work performed per City can be generated by PowerBl. • Previous audits findings are documented in an Audit Progress Tracker updated by SMD staff. 55 Sewer System Management Plan Rosemead /Los Angeles County Public Works Table 9-1: Information Svstems Relevant to SSMP Im Maintenance management system for managing maintenance activities.

The effectiveness of the program is primarily monitored and tracked by overall sewer overflow performance such as amount of sewer spills, spill response time, and reduction of repeated spills. Monthly meetings between SMD Superintendents and Supervisors focus on discussing safety procedures, operational and personnel issues, and the status of spills. Additionally, productivity reports on Power BI are reviewed to track progress in meeting inspection and maintenance targets, which are set and monitored by the superintendents. Collection supervisors meet bi-weekly to go over status and tracking of maintenance activities. These meetings serve as a forum to facilitate communication between SMD Management and SMD Superintendents and Supervisors. 9.3 Program Audits Every three years, LACPW performs an internal audit of the SSMP and the SSMP program implementation. Every three years, the City will perform their own internal audit of the SSMP and the SSMP program implementation. The various LACPW and City's divisions and positions responsible for SSMP implementation, as identified in Table 2-2a and 2-2b, are involved in the audit. Each element of the SSMP is reviewed for effectiveness towards reducing the frequency and/or mitigating the impacts of spills and for compliance with the General Order requirements. Corrective actions to address identified deficiencies are prioritized, scheduled and incorporated into division plans. 9.4 Assessment of Preventative Maintenance Program LACPW assesses the success of its Preventative Maintenance Programs by monitoring spill trends and spill events to identify improvements in their operation. By keeping track of sewer blockages and overflow, LACPW can respond with the appropriate corrective measure and program adjustments. 9.5 Identification and Illustration of Spill trends Data acquisition, analysis, and management of sewer spills is supported by a dynamic information management system. Spill data is visualized in SMD's PowerBl database which allows for the identification and tracking of spill trends. PowerBl can generate spill analysis reports and figures, illustrating these trends and providing the metrics needed to identify spill trends and evaluate the overall success of the SSMP program. This system enables LACPW to review spill performance based on frequency (seasonal variations, year -over -year comparisons), location (known problem areas, system characteristics such as pipe material and installation timeline), and volume (totals reaching surface waters, average volumes, and changes over time, which can indicate the effectiveness of response times). 1 57 Sewer System Management Plan Rosemead /Los Angeles County Public Works 9.6 Approach to Program Modifications and Plan Updates The City and LACPW update the SSMP every six years. The update consists of: • Reviewing the existing SSMP language and updating any outdated information. This includes updates to staff positions, names and organizational lines of authority that have changed, changes to system characteristics such as basin areas, etc. Incorporation of the adopted and implemented recommendations from previous SSMP program audits. Upon completion of the six-year SSMP update, the SSMP is provided to the Board of Supervisors by LACPW and to the City Council by the City with a request for approval. Upon acceptance by the Board for LACPW SSMP update and City Council for the City's SSMP update, the SSMP is uploaded to the State Water Board CIWQS database and certified. SMD also posts the SSMP on the LACPW webpage and City also posts their SSMP on City's webpage. 1 58 Sewer System Management Plan Rosemead /Los Angeles County Public Worcs 10 SSMP Program Audits LACPW and City audit the SSMP and program implementation to identify actions for improving how it manages, operates, and maintains the collection system. This process identifies the tasks and actions that are required to meet SSMP goals and defines and prioritizes them. Cities are responsible for either performing their own SSMP development and audits on their collection systems or requesting support from CSMD to complete their audit through a City Service Request. 10.1 Schedule of Program Audits and Updates LACPW and City perform an internal audit of its SSMP every three years in accordance with General Order requirements. Every six years, LACPW and City update and recertify the SSMP. Table 10-1 shows the anticipated schedule for SSMP audits and updates for the next six years. While the various unincorporated areas have different audit and update cycles, LACPW completes one SSMP audit report covering all collection systems in unincorporated County areas according to the Group 1 schedule. The audit and SSMP update prepared for Group 1 is utilized for all other collection systems in unincorporated County areas. LACPW provide operation and maintenance services for the City's sewer facilities; therefore, some components of the City's audit and SSMP may be similar to LACPWs audit and SSMP update prepared in group 1.

Over the course of approximately three months, the audit team, including representatives from the divisions responsible for each SSMP section, conducts a series of in-person meetings to evaluate the effectiveness of each SSMP Part and Sub -part, identify any deficiencies, and make recommendations for improvements and updates. This process involves reviewing the program documentation in the Sewer System Management Plan, assessing current procedures and practices employed by staff, and discussing potential program modifications to enhance program effectiveness. 10.3 SSMP Audit Report The findings from the SSMP audit are documented in an audit report. The audit report includes the following elements: Audit findings and recommended corrective actions; • A statement that sewer system operators' input on the audit findings has been considered; and • A proposed schedule to address identified deficiencies Once the audit report is complete, a quality check review of the audit report is performed, with a focus on consistency and completeness. The final audit report is reviewed by the CSMD and City's LRO before final acceptance. Audit reports and related materials are maintained in a hard copy and an electronic document tracking and management system. Copies of the SSMP will be maintained in the SMD's Alhambra Headquarters Office and all SMD Maintenance Yards and posted on the LACPWs internet site. A copy of the City's SSMP will be maintained by the City's Director of Public Works at 8838 East Valley Boulevard, Rosemead, CA 91770 and posted on City's webpage. The document shall also be made readily available to State Water Resources Control Board or Regional Water Quality Control Board representatives upon request, to all CMSD cities, and to the operators of any collection system or treatment facility downstream of the LACPW's system. 10.4 Audit Implementation and Tracking of Results The SSMP program audit recommended corrective actions are incorporated into the CIP development and budgeting process to provide the necessary resources to implement audit corrective actions and recommendations. Through that process, implementation progress is measured and reported on an ongoing basis to ensure timely completion of corrective actions. Deficiencies in meeting the schedule are identified or anticipated and mitigation measures developed and implemented to manage completion of the corrective 1 60 Sewer System Management Plan Rosemead /Los Angeles County Public Works actions from the audit. Each subsequent audit update begins with a review of the previous audit to determine if the corrective action remains relevant and, if so, to reiterate the program deficiency and recommended corrective action in the current SSMP audit report. Sewer System Management Plan Rosemead /Los Angeles County Public Works 11 Communication Program LACPW employs a variety of means for communicating with the public and contract agencies on the development, implementation and update of the SSMP. The following sections describe LACPWs procedures for: • Communicating with the public for spills and discharges resulting in closures of public areas, or that enter a source of drinking water. • Communicating with the public on the development, implementation, and update of its SSMP, including opportunities for public input to Plan implementation and updates. • Owners/operators of systems that connect into the Enrollee's system, including tributary systems, for system operation, maintenance, and capital improvement - related activities. 11.1 Procedures to Communicate with Public for Spills and Discharges LACPWs procedures for communication with the public for spills and discharges are included in the Spill Emergency Response Plan in Appendix F. Chapter 3 of these procedures provides instructions for communicating with the public when spills result in closure of public areas or enter a source of drinking water. Within 15 minutes of receiving confirmation that a spill with the potential to reach a storm drain or public waterway has occurred, LACPWs Field Crew must contact Los Angeles County Department of Public Health through LACPWs Operator. The Department of Public Health will post and remove signage for waterways and beach closures as required and will not remove the signs until the effects of the spill have been mitigated. A public press release will be made of temporary closure due to a spill. 11.2 Procedures for General Communication with Public on SSMP LACPW provides operation and maintenance services for the City's collection system.

F-1 ORDER 2022-0103-DWQ December 6, 2022 3 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER INTRODUCTION This General Order regulates sanitary sewer systems designed to convey sewage. For the purpose of this Order, a sanitary sewer system includes, but is not limited to, pipes, valves, pump stations, manholes, siphons, wet wells, diversion structures and/or other pertinent infrastructure, upstream of a wastewater treatment plant headworks. A sanitary sewer system includes: • Laterals owned and/or operated by the Enrollee; • Satellite sewer systems; and/or Temporary conveyance and storage facilities, including but not limited to temporary piping, vaults, construction trenches, wet wells, impoundments, tanks and diversion structures. Sewage is untreated or partially treated domestic, municipal, commercial and/or industrial waste (including sewage sludge), and any mixture of these wastes with inflow or infiltration of stormwater or groundwater, conveyed in a sanitary sewer system. Sewage contains high levels of suspended solids, non -digested organic waste, pathogenic bacteria, viruses, toxic pollutants, nutrients, oxygen -demanding organic compounds, oils, grease, pharmaceuticals, and other harmful pollutants. For the purpose of this General Order, a spill is a discharge of sewage from any portion of a sanitary sewer system due to a sanitary sewer system overflow, operational failure, and/or infrastructure failure. Sewage and its associated wastewater spilled from a sanitary sewer system may threaten public health, beneficial uses of waters of the State. and the environment. This General Order serves as statewide waste discharge requirements and supersedes the previous State Water Resources Control Board (State Water Board) Order 2006-0003-DWQ and amendments thereafter. All sections and attachments of this General Order are enforceable by the State Water Board and Regional Water Quality Control Boards (Regional Water Boards). Through this General Order, the State Water Board requires an Enrollee to: • Comply with federal and state prohibitions of discharge of sewage to waters of the State, including federal waters of the United States; • Comply with specifications, and notification, monitoring, reporting and recordkeeping requirements in this General Order that implement the federal Clean Water Act, the California Water Code (Water Code), water quality control plans (including Regional Water Board Basin Plans) and policies; • Proactively operate and maintain resilient sanitary sewer systems to prevent spills; • Eliminate discharges of sewage to waters of the State through effective implementation of a Sewer System Management Plan; • Monitor, track, and analyze spills for ongoing system -specific performance improvements; and • Report noncompliance with this General Order per reporting requirements. ORDER 2022-0103-DWQ 4 December 6, 2022 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER An Enrollee is a public, private, or other non-governmental entity that has obtained approval for regulatory coverage under this General Order, including: • A state agency, municipality, special district, or other public entity that owns and/or operates one or more sanitary sewer systems: o greater than one (1) mile in length (each individual sanitary sewer system); o one (1) mile or less in length where the State Water Board or a Regional Water Board requires regulatory coverage under this Order; or • A federal agency, private company, or other non-governmental entity that owns and/or operates a sanitary sewer system of any size where the State Water Board or a Regional Water Board requires regulatory coverage under this Order in response to a history of spills, proximity to surface water, or other factors supporting regulatory coverage. For the purpose of this Order, a sanitary sewer system includes only systems owned and/or operated by the Enrollee. 2. REGULATORY COVERAGE AND APPLICATION REQUIREMENTS 2.1. Requirements for Continuation of Existing Regulatory Coverage To continue regulatory coverage from previous Order 2006-0003-DWQ under this General Order, within the 60 -days -prior -to the Effective Date of this General Order, the Legally Responsible Official of an existing Enrollee shall electronically certify the Continuation of Existing Regulatory Coverage form in the online California Integrated Water Quality System (CIWQS) Sanitary Sewer System Database. The Legally Responsible Official will receive an automated CIWQS-issued Notice of Applicability email, confirming continuation of regulatory coverage under this General Order. All regulatory coverage under previous Order 2006-0003-DWQ will cease on the Effective Date of this Order. An Enrollee continuing existing regulatory coverage is not required to submit a new application package or pay an application fee for enrollment under this General Order. The annual fee due date for continued regulatory coverage from previous Order 2006-0003-DWQ to this General Order remains unchanged. A previous Enrollee of Order 2006-0003-DWQ that fails to certify the Continuation of Existing Regulatory Coverage form in the online CIWQS database by the Effective Date of this Order is considered a New Applicant, and will not have regulatory coverage for its sanitary sewer system(s) until: • A new application package for system(s) enrollment is submitted per section 2.2 (Requirements for New Regulatory Coverage) below; and • The new application package is approved per section 2.2.2 (Approval of Application Package (For New Applicants Only)). 2.2. Requirements for New Regulatory Coverage No later than 60 days prior to commencing and/or assuming operation and maintenance responsibilities of a sanitary sewer system, a duly authorized representative that ORDER 2022-0103-DWQ December 6, 2022 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER maintains legal authority over the public or private sanitary sewer system is required to enroll under this General Order by submitting a complete application package as specified below and as provided in Attachment B (Application for Enrollment Form) of this General Order. Unless required by a Regional Water Board, a public agency that owns a combined sewer system subject to the Combined Sewer Overflow Control Policy (33 U.S. Code § 1342(q)), is not required to enroll, under this Order, the portions of its sanitary sewer system(s) that collects combined sanitary wastewater and stormwater. 2.2.1. Application Package Requirements The Application for Enrollment package for new applicants must include the following items: Application for Enrollment Form. The form in Attachment B of this General Order must be completed, signed, and certified by a Legally Responsible Official, in accordance with section 5.1 (Designation of a Legally Responsible Official) of this General Order. If an electronic Application for Enrollment form is available at the time of application, a new applicant shall submit its application form electronically; and Application Fee. A fee payable to the "State Water Resources Control Board" in accordance with the Fee Schedule in the California Code of Regulations, Title 23, section 2200, or subsequent fee regulations updates. The application fee for this General Order is based on the sanitary sewer system's threat to water quality and complexity designations of category 2C or 3C, which is assigned based on the population served by the system. The current Fee Schedule for sanitary sewer systems is listed under subdivision (a)(2) at the following website: Fee Schedule (https://www.waterboards.ca.gov/resources/fees/water quality/). 2.2.2. Approval of Application Package (For New Applicants Only) The Deputy Director of the State Water Board, Division of Water Quality (Deputy Director) will consider approval of each complete Application for Enrollment package. The Deputy Director will issue a Notice of Applicability letter which serves as approved regulatory coverage for the new Enrollee. If the submitted application package is not complete in accordance with section 2.2.1 (Application Package Requirements) of this General Order, the Deputy Director will send a response letter to the applicant outlining the application deficiencies. The applicant will have 60 days from the date of the response letter to correct the application deficiencies and submit the identified items necessary to complete the application package to the State Water Board. 2.2.3. Electronic Reporting Account for New Enrollee Within 30 days after the date of the Approval of Complete Application Package for System Enrollment, a duly authorized representative for the Enrollee shall obtain a CIWQS Sanitary Sewer System Database user account by clicking the "User Registration" button and following the directions on the CIWQS Login Page ORDER 2022-0103-DWQ December 6, 2022 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER (https://ciwqs.waterboards.ca.gov). If additional assistance is needed to establish an online CIWQS user account, contact State Water Board staff by email at CIWQS(a)waterboards.ca.00v. The online user account will provide the Enrollee secure access to the online CIWQS database for electronic reporting. 2.3. Regulatory Coverage Transfer Regulatory coverage under this General Order is not transferable to any person or party except after an existing Enrollee submits a written request for a regulatory coverage transfer to the Deputy Director, at least 60 days in advance of any proposed system ownership transfer. The written request must include a written agreement between the existing Enrollee and the new Enrollee containing: • Acknowledgement that the transfer of ownership is solely of an existing system with an existing waste discharge identification (WDID) number; The specific ownership transfer date in which the responsibility and regulatory coverage transfer between the existing Enrollee and the new Enrollee becomes effective; and • Acknowledgement that the existing Enrollee is liable for violations occurring up to the ownership transfer date and that the new Enrollee is liable for violations occurring on and after the ownership transfer date. The Deputy Director will consider approval of the written request. If approved, the Deputy Director will issue a Notice of Applicability letter which serves as an approved transfer of regulatory coverage to the new Enrollee. 3. FINDINGS 3.1. Legal Authorities 3.1.1. Federal and State Regulatory Authority The objective of the Clean Water Act is to restore and maintain the chemical, physical, and biological integrity of the waters of the United States (33 U.S.C. 1251). The Water Code authorizes the State Water Board to implement the Clean Water Act in the State and to protect the quality of all waters of the State (Water Code sections 13000 and 13160). 3.1.2. Discharge of Sewage A discharge of untreated or partially treated sewage is a discharge of waste as defined in Water Code section 13050(d) that could affect the quality of waters of the State and is subject to regulation by waste discharge requirements issued pursuant to Water Code section 13263 and Chapter 9, Division 3, Title 23 of the California Code of Regulations. A discharge of sewage may pollute and alter the quality of the waters of the State to a degree that unreasonably affects the beneficial uses of the receiving water body or facilities that serve those beneficial uses (Water Code section 13050(1)(1)). ORDER 2022-0103-DWQ December 6, 2022 7 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER 3.1.3 Water Boards Authority to Require Technical Reports, Monitoring, and Reporting Water Code sections 13267 and 13383 authorize the Regional Water Boards and the State Water Board to establish monitoring, inspection, entry, reporting, and recordkeeping requirements. Water Code section 13267(b), authorizes the Regional Water Boards to `require any person who has discharged, discharges, or is suspected of having discharged or discharging, or who proposes to discharge waste within its region... or is suspected of having discharged or discharging, or who proposes to discharge, waste outside of its region that could affect the quality of water within its region shall furnish, under penalty of perjury, technical or monitoring reports which the regional board requires ... In requiring those reports, the regional board shall provide the person with a written explanation with regard to the need for the reports and shall identify the evidence that supports requiring that person to provide the reports." Water Code section 13267(f) authorizes the State Water Board to require this information if it consults with the Regional Water Boards and determines that it will not duplicate the efforts of the Regional Water Boards. The State Water Board has consulted with the Regional Water Boards and made this determination. The technical and monitoring reports required by this General Order and Attachment E (Notification, Monitoring, Reporting and Recordkeeping Requirements) are necessary to evaluate and ensure compliance with this General Order. The effort to develop required technical reports will vary depending on the system size and complexity and the needs of the specific technical report. The burden and cost of these reports are reasonable and consistent with the interest of the state in protecting water quality, which is the primary purpose of requiring the reports. Water Code section 13383(a) authorizes the Water Boards to "establish monitoring, inspection, entry, reporting, and recordkeeping requirements... for any person who discharges, or proposes to discharge, to navigable waters, any person who introduces pollutants into a publicly owned treatment works, any person who owns or operates, or proposes to own or operate, a publicly owned treatment works or other treatment works treating domestic sewage, or any person who uses or disposes, or proposes to use or dispose, of sewage sludge." Section 13383(b) continues, "the state board or the regional boards may require any person subject to this section to establish and maintain monitoring equipment or methods, including, where appropriate, biological monitoring methods, sample effluent as prescribed, and provide other information as may be reasonably required." Reporting of spills from privately owned sewer laterals and systems pursuant to section 5.15 (Voluntary Reporting of Spills from Privately -Owned Sewer Laterals and/or Private Sanitary Sewer Systems) of this General Order is authorized by Water Code section 13225(c) and encouraged by the State Water Board, wherein a local agency may investigate and report on any technical factors involved in water quality control provided the burden including costs of such reports bears a reasonable relationship to the need for the report and the benefits to be obtained therefrom. The burden of reporting private spills under section 5.15 (Voluntary Reporting of Spills from Privately -Owned Sewer Laterals and/or Private Sanitary Sewer Systems) is minimal and is outweighed by the benefit of providing Regional Water Boards an opportunity to respond to these spills ORDER 2022-0103-DWQ December 6, 2022 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER when an Enrollee, which in many cases has a contractual relationship with the owner of the private system, has knowledge of the spills. 3.1.4. Water Board Authority to Prescribe General Waste Discharge Requirements Water Code section 13263(i) provides that the State Water Board may prescribe general waste discharge requirements 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 waste discharge requirements than individual waste discharge requirements. Since 2006, the State Water Board has been regulating over 1,100 publicly owned sanitary sewer systems (See section 3.1.5 (Previous Statewide General Waste Discharge Requirements) of this General Order). California also has a large unknown number of unregulated privately owned sanitary sewer systems. All waste conveyed in publicly owned and privately owned sanitary sewer systems (as defined in this General Order) is comprised of untreated or partially treated domestic waste and/or industrial waste. Generally, sanitary sewer systems are designed and operated to convey waste by gravity or under pressure; system -specific design elements and system -specific operations do not change the common nature of the waste, the common threat to public health, or the common impacts on water quality. Spills of waste from a sanitary sewer system prior to reaching the ultimate downstream treatment facility are unauthorized and enforceable by the State Water Board and/or a Regional Water Board. Therefore, spills from sanitary sewer systems are more appropriately regulated under general waste discharge requirements. As specified in Water Code sections 13263(a) and 13241, the implementation of requirements set forth in this Order is for 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 Regional Water Board and take into account the environmental characteristics of sewer service areas and 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 water quality, costs associated with compliance with these requirements, the need for developing housing within California, and the need to protect sources of drinking water and other water supplies. 3.1.5. Previous Statewide General Waste Discharge Requirements On May 2, 2006, the State Water Board adopted Order 2006-0003-DWQ serving as Waste Discharge Requirements pursuant to Article 4, Chapter 4, Division 7 of the Water Code (commencing with section 13260) for inadvertent discharges to waters of the State. Order 2006-0003-DWQ prohibited discharges of untreated or partially treated sewage. Order 2006-0003-DWQ also required system -specific management, operation, and maintenance of publicly owned sewer systems greater than one mile in length. ORDER 2022-0103-DWQ December 6, 2022 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER To decrease the impacts on human health and the environment caused by sewage spills, the previous Order required enrollees to develop a rehabilitation and replacement plan that identifies system deficiencies and prioritizes short-term and long-term rehabilitation actions. The previous Order also required enrollees to: 1. Maintain information that can be used to establish and prioritize appropriate Sewer System Management Plan activities; and 2. Implement a proactive approach to reduce spills. The previous Order required Sewer System Management Plan elements for "the proper and efficient management, operation, and maintenance of sanitary sewer systems, while taking into consideration risk management." On July 30, 2013, the State Water Board amended General Order 2006-0003-DWQ with Order WQ 2013 -0058 -EXEC, Amending Monitoring and Reporting Program for Statewide General Waste Discharge Requirements for Sanitary Sewer Systems. Many enrollees of Order 2006-0003-DWQ have already implemented proactive measures to reduce sewage spills. Other enrollees, however, still need technical assistance and funding to improve sanitary sewer system operation and maintenance for the reduction of sewage spills. 3.1.6. Existing Memorandum of Agreement with California Water Environment Association The California Water Environment Association is a nonprofit organization dedicated to providing water industry certifications, training, and networking opportunities. The Association's Technical Certification Program provides accredited sanitary sewer system operator certification for collection system operators and maintenance workers. On February 10, 2016, the State Water Board entered into a collaborative agreement with the Association titled Memorandum of Agreement Between the California State Water Resources Control Board and the California Water Environment Association - Training Regarding Requirements Set Forth in Statewide General Waste Discharge Requirements for Sanitary Sewer Systems. The Memorandum sets forth collaborative training necessary for regulated sanitary sewer system personnel to operate and maintain a well operating system and ensure full compliance with statewide sewer system regulations. On March 15, 2018, the State Water Board and the California Water Environment Association amended the existing Memorandum of Agreement to include collaborative outreach and expand training needs associated with further updates to Water Board regulations for sanitary sewer systems. The State Water Board encourages further Agreement updates as necessary to support improved sewer system operations and the professionalism of collection system operators. ORDER 2022-0103-DWQ fibs December 6, 2022 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER 3.2. General 3.2.1. Waters of the State Waters of the State include any surface water or groundwater, including saline waters, within the boundaries of the state as defined in Water Code section 13050(e), and are inclusive of waters of the United States. 3.2.2. Sanitary Sewer System Spill Threats to Public Health and Beneficial Uses Sewage contains high levels of suspended solids, pathogenic organisms, toxic pollutants, nutrients, oxygen -demanding organic compounds, oil and grease and other pollutants. Sewage spills may cause a public nuisance, particularly when sewage is discharged to areas with high public exposure such as streets and surface waters used for drinking, irrigation, fishing, recreation, or other public consumption or contact uses. More specifically, sanitary sewer spills may: • Adversely affect aquatic life and/or threaten water quality when reaching receiving waters; • Inadvertently release trash, including plastics; • Impair the recreational use and aesthetic enjoyment of surface waters by polluting surface water or groundwater; • Threaten public health through direct public exposure to bacteria, viruses, intestinal parasites, and other microorganisms that can cause serious illness such as gastroenteritis, hepatitis, cryptosporidiosis, and giardiasis; • Negatively impact ecological receptors and biota within surface waters; and • Cause nuisance including odors, closure of beaches and recreational areas, and property damage. Sanitary sewer system spills may pollute receiving waters and threaten beneficial uses of surface water and groundwater. Potentially threatened beneficial uses include, but are not limited to the following (with associated acronym representations as included in statewide water quality control plans and Regional Water Boards' Basin Plans): • Municipal and Domestic Supply (MUN) • Water Contact Recreation (REC-1) and Non -Contact Water Recreation (REC-2) • Cold Freshwater Habitat (COLD) • Warm Freshwater Habitat (WARM) • Native American Culture (CUL) • Wildlife Habitat (WILD) • Rare, Threatened, or Endangered Species (RARE) • Spawning, Reproduction, and/or Early Development (SPWN) • Wetland Habitat (WET) • Agricultural Supply (AGR) • Estuarine Habitat (EST) ORDER 2022-0103-DWQ 11 December 6, 2022 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER • Commercial and Sport Fishing (COMM) • Subsistence Fishing (SUB) • Tribal Tradition and Culture (CUL) • Tribal Subsistence Fishing (T -SUB) • Aquaculture (AQUA) • Marine Habitat (MAR) • Preservation of Biological Habitats of Special Significance (BIOL) • Migration of Aquatic Organisms (MIGR) • Shellfish Harvesting (SHELL) • Industrial Process Supply (PROC) • Industrial Service Supply (IND) • Hydropower Generation (POW) • Navigation (NAV) • Flood Peak Attenuation/Flood Water Storage (FLD) • Water Quality Enhancement (WQE) • Fresh Water Replenishment (FRSH) • Groundwater Recharge (GWR) • Inland Saline Water Habitat (SAL) 3.2.3. Proactive Sanitary Sewer System Management to Eliminate Spill Causes Finding 3 of the previous Order, 2006-0003-DWQ, states: "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 [sanitary sewer overflow]. 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." Many spills are preventable through proactive attention on sanitary sewer system management using the best practices and technologies available to address major causes of spills, including but not limited to: • Blockages from sources including but not limited to: o Fats, oils and grease; o Tree roots; o Rags, wipes and other paper, cloth and plastic products; and o Sediment and debris. Sewer system damage and exceedance of sewer system hydraulic capacity from identified system -specific environmental, and climate -change impacts, including but not limited to: ORDER 2022-0103-DWQ December 6, 2022 12 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER o Sea level rise impacts including flooding, coastal erosion, seawater intrusion, tidal inundation and submerged lands; o Increased surface water flows due to higher intensity rain events; o Flooding; o Wildfires and wildfire induced impacts; o Earthquake induced damage; o Landslides; and o Subsidence. • Infrastructure deficiencies and failures, including but not limited to: o Pump station mechanical failures; o System age; o Construction material failures; o Manhole cover failures; o Structural failures; and o Lack of proper operation and maintenance. Insufficient system capacity (temporary or sustained), due to factors including but not limited to: o Excessive and/or increased storm or groundwater inflow/infiltration; o Insufficient capacity due to population increase and/or new connections from industrial, commercial and other system users; and o Stormwater capture projects utilizing a sanitary sewer system to convey stormwater to treatment facilities for reuse. • Community impacts, including but not limited to: o Power outages; o Vandalism; and o Contractor -caused or other third party -caused damages. 3.2.4. Underground Sanitary Sewer System Leakage Portions of some sanitary sewer systems may leak, causing underground exfiltration (exiting) of sewage from the system. Exfiltrated sewage that remains in the underground infrastructure trench and/or the soil matrix, and that does not discharge into waters of the State (surface water or groundwater) may not threaten beneficial uses. Underground exfiltrated sewage may threaten beneficial uses if discharged to waters of the State. Exfiltrated sewage that discharges to groundwater may impact beneficial uses of groundwater and pollute groundwater supply. Additionally, if in close proximity, exfiltrated sewage may enter into a compromised underground drainage conveyance system that discharges into a water of the United States, or into groundwater that is hydrologically connected to (feeds into) a water of the United States, thus potentially causing: (1) a Clean Water Act violation, (2) threat and impact to beneficial uses, and/or (3) surface water pollution. ORDER 2022-0103-DWQ ik3 December 6, 2022 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER 3.2.5. Proactive Sanitary Sewer System Management to Reduce Inflow and Infiltration Excessive inflow (stormwater entering) and infiltration (groundwater seepage entering) to sanitary sewer systems is preventable through proactive sewer system management using the best practices and technologies available. The efficiency of the downstream wastewater treatment processes is dependent on the performance of the sanitary sewer system. When the structural integrity of a sanitary sewer system deteriorates, high volumes of inflow and infiltration can enter the sewer system. High levels of inflow and infiltration increase the hydraulic load on the downstream treatment plant, which can reduce treatment efficiency, lead to bypassing a portion of the treatment process, cause illegal discharge of partially treated effluent, or in extreme situations make biological treatment facilities inoperable (e.g., wash out the biological organisms that treat the waste). 3.3. Water Quality Control Plans, Policies and Resolutions The nine Regional Water Boards have adopted region -specific water quality control plans (commonly referred to as Basin Plans) that designate beneficial uses, establish water quality objectives, and contain implementation programs and policies to achieve those objectives. The State Water Board has adopted statewide water quality control plans, policies and resolutions establishing statewide water quality objectives, implementation programs and initiatives. 3.3.1. State Water Board Antidegradation Policy On October 28, 1968, the State Water Board adopted Resolution 68-16, titled Statement of Policy with Respect to Maintaining High Quality of Waters in California, which incorporates the federal antidegradation policy. Resolution 68-16 requires that existing water quality be maintained unless degradation is justified based on specific findings. The continued prohibition of sewage discharges from sanitary sewer systems into waters of the State aligns with Resolution 68-16.

This plan provides guidelines for the County of Los Angeles District's maintenance crew to follow in responding to, cleaning up, and reporting sewer spills that may occur within the Consolidated and Manna Sewer Maintenance District's service area. 1.1 Regulatory Requirements The Districts arerequired to have an up-to-date Spill Emergency Response Plan to ensure prompt detection and response to spills to reduce spill volumes and collect information for prevention of future spills. The Spill Emergency Response Plan must include procedures to: • Notify primary responders, appropriate local officials, and appropriate regulatory agencies of a spill in a timely manner, • Notify other potentially affected entities (for example, health agencies, water suppliers, etc.) of spills that potentially affect public health or reach waters of the State; • Comply with the notification, monitoring and reporting requirements of this General Order, State law and regulations, and applicable Regional Water Board Orders, • Ensure that appropriate staff and contractors implement the Spill Emergency Response Plan and are appropriately trained; • Address emergency system operations, traffic control and other necessary response activities; • Contain a spill and prevent/minimize discharge to waters of the State or any drainage conveyance system; • Minimize and remediate public health impacts and adverse impacts on beneficial uses of waters of the State; • Remove sewage from the drainage conveyance system; • Clean the spill area and drainage conveyance system in a manner that does not inadvertently impact beneficial uses in the receiving waters; • Implement technologies, practices, equipment, and interagency coordination to expedite spill containment and recovery; • Implement pre -planned coordination and collaboration with storm drain agencies and other utility agencies/departments prior, during, and after a spill event; • Conduct post -spill assessments of spill response activities; • Document and report spill events as required in this General Order, and • Annually, review and assess effectiveness of the Spill Emergency Response Plan, and update the Plan as needed. March 2025 1 3 Spill Emergency Response Plan Los Angeles County. Department of Public Works 2 Spill Detection and Dispatch to Investigate The processes employed to notify Districts maintenance staff of the occurrence of a spill include: observation by the public, calls from outside agencies such as the cities served by the Districts, Los Angeles County Sheriff's Department, Los Angeles County Fire Department or Public Works, receipt of an alarm, or observation by Districts staff during the normal course of their work. The Sewer Maintenance Districts provide 24-hour emergency services to investigate complaints from citizens. The 24-hour emergency telephone number is 1 -800 -675 -HELP (4357). Personnel are available each day of the year to receive and act on any calls or automated alarms related to problems in the sewer system including overflows. During business hours, compliant calls are received by the Department of Public Works' Operator. The Operatorwill dispatch the nearest Sewer Maintenance crew to the problem site. Normal Business hours are Monday through Friday from 6:30 a.m. to 5:00 p.m. For after -hour calls (i.e., any calls outside of business hours), the Operator will call the Sewer Maintenance Superintendent or Supervisor in the order listed on the Emergency Home Telephone list. The Superintendent or Supervisor who receives the emergency call will investigate the complaint and take appropriate action, including immediate dispatch of a standby crew with necessary equipment to take care of the problem or referthe call to other agencies if the problem is found not to be in our jurisdiction. All contact information can be found in the Combined Resources Phone List in Appendb( A. 4 1 March 2025 Spill Emergency Response Plan Los Angeles County, Department of Public Works 3 Spill Response Procedures Sewer service calls are high priority events that demand a prompt response to the location of the problem. During normal working hours, the nearest Sewer Maintenance Crew is the Primary Responder. During after hours, the staff assigned to the Emergency Call List is the Primary Responderwho will investigate the service call to determine the appropriate response. All contact information can be found in the Combined Resources Phone List in Appendix A. The response procedures for spills caused by sewers managed by the Department of Public Works along with a notification table are depicted in Appendix B. The following information provides the orderof operations forcrew response procedures relating to spills: The crew shall also document the overflow with photographs of the point of overflow, property damage, traffic control, containment method, and point of entry to storm drain system. At this time, crews identify the probable cause of the overflow (i.e. grease, roots, rocks, etc.)and then remedial actions are taken to ensure the mainline is down and running normal. The complainant of the overflow is informed of the cause of the problem and the remedial action taken. 3.1 Safety All responding Districts personnel are responsible forfollowing Los Angeles County Public Works safety procedures at all times. Assume that the overflow contains hazardous materials, particularly if it occurs in an industrial area. Crews shall stay upwind of arty potential air contamination orf umes until it is determined to be safe to approach the origin of the spill. If hazardous materials are suspected, ourcrews are to notify the Department of Public Works' Dispatch Unit so that a Hazmat investigation can be made immediately. 3.2 Traffic and Crowd Control Traffic control requirements vary depending on the location and the risk to operating personnel and the public. The Districts use the following traffic control devices, as appropriate: • Warning signs (signs with the symbol for person working are preferred); • Directional arrow signs on rear of the truck; • Traffic cones clearly delineating traffic lanes and directions, and • One or more flaggers utilized to control and direct traffic where visibility is limited or the possibility of collision exits. Place warning signs, cones, barricades and caution tape as needed to keep vehicles and pedestrians away from contact with spilled sewage. March 2025 1 5 Spill Emergency Response Plan Los Angeles County, Department of Public Worcs 3.3 Primary Responder Priorities The Primary Responder's priorities, as the first person to respond to the call, are: • To follow safe work practices; • To respond promptly with appropriate equipment; • To contain the spill wherever feasible; • To restore the flow as soon as practicable; • To minimize public access to and/or contact with the spilled sewage; • To ensure proper cleanup has occurred with contractor, and • To restore the area to its original condition (or as close as possible). 3.4 Initial Response Upon notification of a possible sewer spill to the Public Works 24-hour Emergency phone number, the operator receiving the call gathers as much information as available through the caller. Information typically available includes the time the spill was noticed, address of the spill, general location of the spill (street, alley, easement, parking lot, private property, etc.) as well as a call back telephone number of the calling party in case additional information is needed. The Service request form to befilled by theoperatorafter receiving the notification of a spill is provided in Appendix C. The receiving operatorwill call the nearest crew during normal working hours orthe staff assigned to the Emergency Call List during after-hours. All known information about the spill will be provided to the responding party. Upon arrival, the responding crew will • Field verify the address and nearest cross street to determine whether the spill or backup is located in LACPW's service area. If in LACPW s service area, call the County Operator within 75 minutes to notify Department of Public Health. Notify the responsible maintenance agency if it is not a LACPW facility. • Note arrival time at spill site. • Use best judgment to determine whether to proceed immediately with blockage removal versus containment. • If the spill/backup is caused by a private lateral, the responding crew should contain/mitigate the spilled sewage to prevent sewage from entering the public right of way without LACPW staff going on private property. • Set up absorbent socks or sandbags to prevent flowfromentering any nearby storm drain or catch basin. The cleaning truck crew will also locate the dry sewer manhole for the jetter truck to clear the upstream stoppage. • Setup traffic and pedestrian control as necessary for safety of the public and the response crew. 6 1 March 2025 Spill Emergency Response Plan Los Angeles County, Department of Public Works 3.4.1 Restore Flow Using the appropriate cleaning tools, the LACPWs jetter truck will set up downstream of the blockage and hydro clean upstream from a clear manhole. The crew will 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 the sewer requires construction repairs to restore flow, then initiate additional containment measures and/or bypass pumping. • If the blockage is too large for the sewer operations crew to bypass, Sewer Maintenance Division will access additional resources through Emergency On - Call contracts to assist with a larger bypass. 3.4.2 Initiate Spill Containment Measures The responding crew should attempt to contain as much of the spilled sewage as possible using the following steps: • Determine the immediate destination of the overflowing sewage. Department of Public Works, Stormwater Maintenance Division (SWMD), is notified of all overflows that discharge into the storm drain system orflood control channel. SWMD's role is to assist in tracing and capturing as much of the spill before it reaches waters of the United States. A sewage spill greater than 1,000 gallons and likely to entera facility is considered a significant release and should be handled in the same way as an illicit discharge as per County of Los Angeles Department of Public Works' Stormwater Maintenance Division'lllicit Discharge Emergency Response Procedures'. The SWMD Illicit Discharge Emergency Response Flowchart is shown in Appendix D. Implement immediate containment measures consisting of containing flowfrom reaching catch basins using absorbent socks, and/or other dam construction material to contain the spill, whenever appropriate. Additional containment measures include containing/directing thespilled sewage by digging a dike/dam or using sandbags. • LACPW is only responsible for sewer mainline maintenance and is not responsible for maintenance of any portion of the private property sewer lateral. The private property sewer lateral extends from the building to the connection at the sewer mainline. If the spill is caused by a sewer lateral, LACPW will check the mainline and ensure this is clear. If this is not, LACPWw 11 proceed to unblockthe line to restore flow. If the mainline is clear of any blockages, LACPW will contact the owner of the lateral, who will be responsible to contacta plumberto clearthe blockage and restore flow. General precautions for sewage contamination on residential property is detailed below: March 2025 1 7 Spill Emergency Response Plan Los Angeles County, Department of Public Works General Precautions for Sewage Contamination of Residential Property If a sewer backup caused flooding in a home, the property owner should: • Keep people and pets away from the affected area(s). • Do not attempt to clean it themselves. • Tum off central heat and air-conditioning systems and prevent flow from reaching floorvents by using towels or blankets as a bene. Remove the vent cover and stuff a towel in the opening to help prevent the flow from entering. • Leave items in the affected area for the experts to handle. Homeowner Responsibilities: The homeowner is responsible forclearing any blockage in the home's plumbing system or private lateral and forany resulting flood damageto the structure. The homeowner is also responsible for damage that happens because a lateral was not properly installed. If the sewage flooding was caused by blockage in the private sewer lateral: • Call an experienced restoration company for cleanup and removal of affected surfaces. Report a claim to the homeowner's insurance carrier. • If there was recent plumbing work performed, contactthe plumberor contractor. If the sewage flooding was caused by a blockage in the public sewer main, LACPW may be responsible forthe damages. If this occurs, the property owner will file a claim as soon as possible, and LACPWwill respond accordingly. If a blockage occurs in the private sewer lateral, it is the homeowner's responsibility to clear the blockage. All blockages occurring in the Private Sewer Lateral, are the responsibility of the homeowner. 3.5 Water Quality Sampling and Testing As part of this effort, a waterquality monitoring plan was developed for LACPW as shown in Appendix E. Spill volume estimation can be determined following one of the steps in Appendix F. 3.6 Recovery and Clean Up 3.6.1 Recovery of Spilled Sewage Use a vacuum truck to vacuum up all spilled sewage and any water used to flush the area. 3.6.2 Clean Up and Disinfection Implement clean up and disinfection procedures to reduce the potential for human health issues and adverse environmental impacts that are associated with a spill event. The procedures described are fordry weather conditions and should be modified as required for wet weather conditions. 8 1 March 2025 Spill Emergency Response Plan Los Angeles County, Department of Public Works Hard Surface Areas Take reasonable steps to contain and vacuum up the wastewater. Collect all signs of sewage solids and sewage -related material either by hand or with the use of rakes and brooms. Wash down the affected area with high pressure water using nozzles on provided on the hydro/combo unit and vacuum the wash water utilizing the hydro/combo unit. Allow area to dry. Repeat the process if additional cleaning is required. Use disinfection. Landscaped and Unimproved Natural Vegetation If spill occurs in landscape, either flush the landscape with wash water or take off the top inch or the amount that has been affected and replace the soil. The approach will be determined by the Primary Responder. Wet Weather Modifications Omit flushing and sampling during heavy storm events with heavy runoff where flushing is not required and sampling would not provide meaningful results. 3.6.3 Follow Up Activities If sewage has reached the storm drain system, use the hydro/combo unit to vacuum/pump out the catch basin. Flush the storm drain system with wash water and capture all residual wash water at a point of containment downstream. Stormwater Maintenance Division staff will request the amount/quantity of storm drain to clean/flush. If LACPW sewer causes an overflowon a private property, a remediation contractorwill be called to clean and sanitize the affect areas of the home. If the blockage occurs in the main, LACPW will report this as a spill and restore flow. The Primary Responder will notify the Sewer Operations Superintendent or Supervisor to determine if any immediate steps to rectify the issue are required. Provide the customer with the contact information of LACPW to make a claim, pending investigation. 3.7 Public Notification If a spill enters the ocean ora waterway requiring posting of signage, contact Los Angeles County Department of Public Health through the County Operator. The Department of Public Health will post and remove signage for waterways and beach closures as required and will not remove the signs until the effects of the spill have been mitigated. A public press release will be made of the temporary closure due to a spill. 3.8 Spill Event Investigation The objective of the spill event investigation is to determine the cause of the spill and to identify corrective action(s) needed that will reduce or eliminate potential forthe spill to recur. The investigation includes reviewing all relevant data to determine appropriate corrective action(s)forthe line segment. The investigation will beconducted by the Supervisorand/or and reported to the Superintendent or his/her designee. The investigation should include. March 2025 1 9 Spill Emergency Response Plan Los Angeles County.. Department of Public Worcs • A review of and verification of the information reported on the Spill Report Form (Appendix G); • A review of available photographs; • A review of historical maintenance activities; • Completion of a postspiB CCN inspection to determine the condition of the line segment immediately upstream and downstream of the spill and review the results. • A review of the results of a FOG source control investigation, if the spill is FOG - related; and • Debrief with staff who responded to the spill. The goal of the spill event investigation is to determine the cause of the spill event and to identify appropriate corrective actions. LACPWs standard practice is, at a minimum, to perform a CCTV inspection of the pipe containing the blockage that caused the spill event along with the pipes immediately upstream and downstream to find a resolution on how to decrease the chance this will happen again. LACPW has a book of sewer cleaning periodics for pipe segments that are cleaned more frequently. These are put on a more regular cleaning schedule to reduce the potential of another spill if one had occurred previously. 10 1 March 2025 Spill Emergency Response Plan Los Angeles County, Department of Public Works 4 Spill Documentation and Reporting 4.1 Spill Categories The Calif omia State Water Resources Control Board (SRWCB) has established guidelines for classifying and reporting sewers pills. Reporting and documentation requirements vary based on the type of spill. Currently, there are four categories of spills as defined by the SWRCB and shown in Table 4-11. Table 4-1: Spill Categories and Definitions CATEGORY 1 A Category 1 spill is a spill of any volume of sewage from or caused by a sanitary sewer system regulated under the General Order that results in a discharge to: • Asurface water, including asurfacewater body thatcontains no flow or volume of water; or • A drainage conveyance system that discharges to surface waters when the sewage is not fully captured and returned to the sanitary sewer system or disposed of properly. Any spill volume not recovered from a drainage conveyance system is considered a dischargeto surfacewater, unless the drainage conveyance system discharges to a dedicated stormwater infiltration basin or facility. A spill from a Districts -owned and/or operated lateral that discharges to a surface water is a Category 1 spill; the Districts shall report all Category 1 spills per section 3.1 of Attachment E1 (Notification, Monitoring, Reporting and Recordkeeping Requirements) of the General Order. CATEGORY 2 A Category 2 spill is a spill of 1,000 gallons or greater, from or caused by a sanitary sewer system regulated under the General Order that does not discharge to a surface water. A spill of 1,000 gallons orgreater thatspilis outof a lateral and is caused by a failure or blockade in the sanitary sewer system, is a Cateqory 2 spill. CATEGORY A Category 3 spill is a spill of equal to orgreater than 50 gallons and less than 1,000 gallons, from or caused by a sanitary sewer system regulated under this General Order that does not discharge to a surface water. A spill of equal to or greater than 50 gallons and less than 1,000 gallons, that spills out of lateral and is caused by a failure or blockage in the sanitary sewer system is a Catedory 3 spill. CATEGORY 4 A Category 4 spill is a spill of less than 50 gallons, from or caused by a sanitary sewer system regulated under this General Order that does not discharge to a surface water. A spill of less than 50 gallons that spills out of a lateral and is caused by a failure or blockaqe in the sanitary sewer system is a Cateqory 4 spill. 4.2 Internal Spill Reporting Procedures State Water Resources Control Board General Order for Sanitary Sewer Systems, Order WQ 2022- 0103-D WQ March 2025 1 11 Spill Emergency Response Plan Los Angeles County, Department of Public Woks The Primary Responder will fill out the Service Request Form (Appendix C) and the Spill Report Form (Appendix G) and tum it in to the Superintendent or Supervisor.

Water Quality Monitoring Program To comply with of the State Water Resources Control Board Order No. WQ 2022-0103-DWQ, the County has developed and implemented this Water Quality Monitoring Program to assess impacts from spills. The Water Quality Monitoring Program required by the General Order, shall include, at minimum: 1. Contain protocols for water quality monitoring. 2. Account for spill travel time in the receiving water and scenarios where monitoring may not be possible (e.g. safety, access restrictions, etc.). 3. Require samples and measurements taken forthe purpose of monitoring be representative of the monitored activity. 4. Require water quality analyses forammonia and bacterial indicators to be performed by an accredited and certified laboratory. 5. Require monitoring instruments and devices used to implement the 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. 6. Within 48 hours of the staff becoming aware of the spill, require water quality sampling for, at a minimum, the following constituents: Ammonia. ii. Appropriate Bacteria[ indicator(s) perthe applicable Basin Plan waterquality objective or Regional Board direction which may include total and fecal coliform, enterococcus, and ecoli. Safety All County staff shall be aware and followall safety precautions in orderto complywith this Water Quality Monitoring Program. Therefore, all staff needs to take into account where monitoring will not be possible which may include: 1. Heavy rain / storm events where access points may be compromised; 2. Flooding around lowareas; or 3. Fast moving waters. County staff should evaluate and keep safetyfirst when encountering these scenarios and are encouraged to exercise properjudgment to limit health risk. Water Quality Sampling The LA County currently does not have an ELAP certified laboratory on site. Hence, a third -party laboratory will perform sampling and testing for the County. For sewage spills in which an estimated 50,000 gallons orgreater are discharged into a surface water, the County Staff shall conduct the following water quality sampling no later than 48 hours after the County staff's knowledge of a potential discharge to a surface water. 32 1 March 2025 Spill Emergency Response Plan Los Angeles County, Department of Public Works Collect one water sample, each day of the duration of the spill, at: 1. The DCS -001 location as described in Table 1 below if sewage discharges to a surface water via a drainage conveyance system; and/or 2. Each of the three receiving water sampling locations in Table 1. Sampling of flow in Drainage Conveyance System (DCS) Prior to Discharge Sampling Location Sampling Location Description A point in a drainage conveyance system before the drainage DCS -001 conveyance system flow discharges into a receiving water. Receiving Surface Water Sampling (RSW)1 Sampling Location Sampling Location Description RSW-001 A point in the receiving water where sewage initially enters the receiving water. Point of Discharge RSW-001U: A point in the receiving water, upstream of the point of sewage Upstream of Point of Discharge discharge, to capture ambient conditions absent of sewage discharge impacts. RSW-001D: A point in the receiving water, downstream of the point of sewage Downstream of Point of Discharge discharge, where the spill material is fully mixed with the receiving water. 1 The staff must use their best professional judgment to determine the upstream and downstream distances based on receiving water flow, accessibility to upstream/downstream waterbody banks, and size of visible sewage plume. If the receiving water has no flow during the duration of the spill, the staff must report "No Sampling Due to No Flow" for its receiving water sampling locations. Collect one water sample, each day of the duration of the spill. Coordinate with the regional water board to determine if additional sampling is required or if the spill is beyond 50,000 gallons. Samples collected inthe field must follow Standard Methods(APHA2005) collection protocol. Sample must be collected in a watertight, sterile container. Label the sample container with the location of the spill and sample collection time. If the sample cannot be delivered to lab within 1 hour, it must be placed on ice immediately and delivered to the lab within six hours of collection. Any sample not meeting these criteria is "Invalid". Recommended container is a 4 oz Sterile Sample Container, Fisher Brand Catalog No. 14-375-147 or equivalent. Sample Delivery after working hours: The sample collectors will notify lab staff of delivery and deliver samples. These samples must meet the required six -hour delivery (holding) time to be considered valid. Analysis: The lab shall analyze the collected receiving water samples for the following constituents: March 2025 1 33 Spill Emergency Response Plan Los Angeles County, Department of Public Works 1. Ammonia, and 2. Appropriate bacterial indicator(s) per the applicable Basin Plan water quality objectives, including one or more of the following, unless directed otherwise by the Regional Water Board: i. Total Coliform Bacteria ii. Fecal Coliform Bacteria iii. Ecoli iv. Enterococcus Spill monitoring must be representative of the monitored activity as adhering to the following requirements: Sufficiently Sensitive Methods Sample analysis must be conducted according to sufficiently sensitive test methods approved under 40 Code of Federal Regulations Part 136 (eCFR :: 40 CFR 136.6 — Method modifications and analytical reouirements.) for the sample analysis of pollutants. Forthe purposes of this General Order, a method is sufficiently sensitive when the minimum level of the analytical method approved under40 Code of Federal Regulations Part 136 is at or below the receiving water pollutant criteria. Water Quality Sampling Equipment The following guideline describes the equipment and supplies to be stocked at the third party laboratory and readily available for any water quality sampling event. 1.

Disposable un -powdered gloves are recommended for sample collection to protect you and to assure the integrity of the samples. Disposable gloves should be changed at each sampling location. 2. Determine the correct location for sample collection. 3. Samples for bacteria/coliform analysis shall be collected in a sterile, container. Sampler will submerge container, midstream of the effluent, point top into the effluent, remove cap and fill container to fill line, oras close as possible in an effort to allowair space in the container for mixing. Label sample bottle with: i. sampling site ii. date and time sampled iii. Initials 4. Keep the samples packed on blue ice or equivalent for delivery to the laboratory. 5. Deliver all samples to the laboratory within 6 hrs. 6. Fill out Chain of Custody (COC) with the same information to match the sample bottles. Completethe COC as thoroughly as possible with you and yoursupervisor's namesand phone numbers. Be sure to relinquish the COC with your signature, printed name, date, and time. Water Quality Analysis -Protocols Typical monitoring parameters may include Ammonia, total and fecal coliform bacteria, or other analyses as required. Laboratory: All samples will be sent to the Laboratory. The laboratory methods will be performed according to the laboratory's Standard Operation Procedures (SOPS). Maintenance and Calibration of Monitoring Instruments and Devices: In orderto be accredited and maintain their certification, the Laboratory identified will followstringent quality assurance and quality control protocols that includes regular monitoring, calibration and maintenance of their equipment. The frequency of monitoring and calibration varies based on equipment type and method requirements. Records of the calibration receipts are kept on file and readily available up on request. Reporting Requirements The Laboratory Supervisor will provide reporting results to the LRO. The LRO is responsible for submitting water quality monitoring information with the certified respective spill report on CIWOS database within 15 calendar days of the spill end date. The LRO is also responsible for submitting information related to the Technical Report in CIWQS database, which must be completed within 45 calendar days of the spill end date. The Spill Technical Report must include the following water quality monitoring information: March 2025 1 35 Spill Emergency Response Plan Los Angeles County, Department of Public Works 1. Description of all water quality sampling activities. 2. Analytical results and evaluation of the results; and 3. Detailed location maps and photos depicting all water sampling points. 36 1 March 2025 Spill Emergency Response Plan Los Angeles County, Department of Public Works Appendix F. LACPW Methods for Estimating Spill Volume A variety of approaches exist for estimating the volume of a sanitary sewer spill. 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 spill 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 TRIANGI.Ee H w E I D METER I D H H T 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 0.79 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 gallons. METHOD 3 DURATION AND FLOWRATE March 2025 1 37 Spill Emergency Response Plan Los Angeles County, Department of Public Works 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 flowrate. The methods of estimating duration and flowrate 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: • 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. • Changes in flow on a downstream flowmeter can be used to establish the start time. Typically, the daily flow peaks are "out off" or flattened by the loss of flow. This can be identified by comparing hourly flowdata during the spill event with flow data from prior days. • Conditions at the spill site change over time. Initially there will be limited deposits of toilet paper and other sewage solids. Altera few days to a week, the sewage solids forma light- colored residue. After fewweeks to a month, the sewage solids tum dark. The quantity of toilet paper and other materials of sewage origin increase overtime. 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. • 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 occuronly 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 flowrate is the average flow that left the wastewater collection system during the time of the spill. There are three common ways to estimate the flowrate: • The San Diego Manhole Flowrate Chart: This chart, included on the following page, shows sewage flowing from manhole covers at a variety of flowrates. The observations of the field crew can be used to select the appropriate flowrate from the chart. If possible, photographs are useful in documenting the basis for the flowrate estimate. Flowmeter: Changes in flows in downstream flowmeters can be used to estimate the flowrate during the spill. • 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 x 9 gallons per hour per connection 38 1 March 2025 Spill Emergency Response Plan Los Angeles County, Department of Public Works = 198 gallons per hour / 60 minutes per hou-3.3 gallons per minute Spill Volume: Once duration and flowrate have been estimated, the volume of the spill is the product of the duration in hours or days and the flowrate in 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 hou-594 gallons MANHOLE SPILL FLOWRATE GUIDE Oty of San Dm o ' MMOPOM n Wasteraw DopaNpnt Reference Sheet for Estimating Sewer Spills from Overflowing Sewer Manholes All.r••u7.::..r -a ktdaNOIn,a, r,o rvPml WasMwabrCatloceon DMYon 161):54-4160 2 LBaAobswfenFm Ong.6enmmnb,rnanneeaoa a..Mo-�+rn:.xw,�..:.puri n._ r.1f Dbg SMl Iomay.r. METHOD 4 SINGLE HOME —Na This estimation method works only for single family residential home spills. It assumes 180 gallons per EDU. Single -Family Residential homes = One EDU. 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) March 2025 139 Spill Emergency Response Plan Los Angeles County, Department of Public Works 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 laundry (30 gallons/load) or ran the dish washer (9 gallons/load) or taken a shower (25 gallons) Next, put all 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? Use the following and consider it to be Typical Use for each activity. The amounts listed below consider the water use difference of newerappliances and older appliances. It appears that around 1994 was watershed year. The amounts listed below assume that more appliances are newer than older.
