CITY OF SIMI VALLEY
MEMORANDUM
April 21, 2025
TO: City Council
FROM: Department of Public Works
SUBJECT: ADOPTION OF AN UPDATED AND REVISED SEWER SYSTEM
MANAGEMENT PLAN
STAFF RECOMMENDATION
It is recommended that the City Council adopt an updated and revised Sewer System Management Plan (SSMP) (Attachment A, page 4).
BACKGROUND AND OVERVIEW
As of June 5, 2023, the Statewide Waste Discharge Requirements (WDR) General Order for Sanitary Sewer Systems, Order No. 2022-0103-DWQ (Attachment B, page 76), now serves as the new statewide waste discharge requirements regulating sanitary sewer systems with the requirement to implement and update a SSMP. This Order requires all California public agencies operating a sanitary sewer system greater than one mile in length to develop and implement a SSMP and update the plan every six years, beginning May 2, 2025. The City Council adopted the previous SSMP update on April 22, 2019.
The SSMP creates a plan of action to reduce sanitary sewer overflows and maintain a reliable system. The goals are to facilitate sewer system management, operation, and maintenance to sustain the infrastructure, protect public health, protect the environment, and achieve compliance with all regulations. The City certified and received a Notice of Applicability (Attachment C , page 155 ) as confirmation of the Continuation of Existing Regulatory Coverage under the new Order.
FINDINGS AND ALTERNATIVES
The original SSMP was approved and adopted by the City Council at a public meeting on April 7, 2014. A five-year update was approved and adopted on April 22, 2019. The six- year SSMP update must also be approved and certified, as do all significant updates. The SSMP, all references in the document, and the adoption documents by the City Council are available on the city’s website or submitted to the S tate Water Resources Control Board (SWRCB) upon adoption or recertification. Enrollees do not send their SSMP to the State or Regional Water Boards for review or approval but must make it publicly available and upload an electronic copy to the California Integrated Water Quality System (CIWQS) database.
AGENDA ITEM NO.
Consent (2)
The SSMP has been updated and revised in compliance with Order No. 2022-0103-DWQ, Statewide General WDR for Sanitary Sewer Systems . It required updating the Element sections: Goals and Introduction ; Organization; Legal Authority; Operation and Maintenance Program ; Design and Performance Provisions; Spill Emergency Response Plan; Sewer Pipe Blockage Control Program; System Evaluation, Capacity Assurance, Capital Improvements; Monitoring, Measurement, Program Modifications; Internal Audits; and Communication Program including the following updates and edits:
• Updated the Sewer Spill/Backup Response Workbook
• Updated the Sewer System Service Area Map
• Updated the historical summary of sanitary sewer system overflows • Updated the Responsible and Authorized Representatives • Updated the vehicle equipment inventory
• Updated the required Training
• Update Plan Capital Improvement Program based on Closed Caption Television Assessment
• Made edits to make the document easier to read
Updating and filing the SSMP is self-enforced; therefore, the city maintains all records related to updating the SSMP and its adoption by the City Council . A copy must be immediately available to regulatory agencies upon request and must be publicly available.
The updated SSMP is available at www.simivalley.org/SSMP, in the City Clerk’s Office, and at the Department of Public Works. City staff must self-audit the SSMP annually for the first two years following adoption and biennially thereafter. The SSMP is exempt from the California Environmental Quality Act (CEQA) pursuant to Section 15308 of the CEQA Guidelines.
The following alternatives are available to the City Council:
1. Adopt an updated and revised Sewer System Management Plan;
2. Do not adopt the updated Sewer System Management Plan and provide staff with further direction.
Staff recommends Alternative No. 1.
SUGGESTED CITY COUNCIL MOTION
I move to adopt the updated Sewer System Management Plan.
SUMMARY
The SWRCB requires that the City develop and implement a SSMP and update the plan every six years, beginning May 2, 2025. The City Council previously adopted an updated SSMP on April 22, 2019. Under General Order 2022-0103-DWQ, staff has prepared an updated and revised SSMP and is recommending that the City Council adopt the updated 2 SSMP. The updated SSMP is available at www.simivalley.org/SSMP, in the City Clerk’s Office, and at the Department of Public Works.

Sewer System Management Plan Goals
The City of Simi Valley Sewer System Management Plan (SSMP) is a living planning document that documents ongoing local sewer system management program activities, procedures, and decision making, and which aims to achieve the following three goals:
1. To effectively manage, operate, and maintain all parts of the sanitary sewer system,
2. To reduce and prevent spills, and
3. To contain and mitigate spills.
The information and data presented in this SSMP demonstrates its continued effectiveness to meet or exceed these goals, thus providing a cost effective, proactive management tool for the City’s collection system.
Regulatory Context
Sanitary sewer overflows, or spills, are a critical water quality issue in the State of California. On May 2, 2006, under Order No. 2006-0003-DWQ, the State Water Resources Control Board (SWRCB) issued the Statewide General Waste Discharge Requirements for Sanitary Sewer Systems. On December 6, 2022, under Order No. WQ 2022-0103-DWQ, the SWRCB issued the Statewide Waste Discharge Requirements General Order for Sanitary Sewer Systems, which become effective on June 5, 2023.
Order No. WQ 2022-0103-DWQ requires agencies that own and/or operate a sanitary sewer system greater than one mile in length to develop and implement a Sewer System Management Plan. The City Council first adopted an SSMP in 2009, in response to Order No. 2006-0003- DWQ, and the City has kept it updated and internally audited as required since then.
Sewer System Management Plan Update Schedule
In accordance with Order No. WQ 2022-0103-DWQ, the City SSMP is updated and re-certified by its City Council at least every six years; this was last completed in April of 2019.
Introduction / Sewer System Asset Overview
The City of Simi Valley is situated Ventura County. The City maintains approximately 380 miles of sewer line, 7,500 manholes, and 3 lift stations with pipelines ranging from 6” to 48” that transport wastewater from residential and commercial properties to the wastewater treatment plant. The city serves a population of 126,365 people. The systems average daily flow is currently at 7.9 MGD.
9 The City’s records indicate a very low rate of spills, based upon the ratio or metric of spills per 100 miles of sewer. In the past five years the collection system has had an average of 3.6 spills per year and averaged less than 1 spill per hundred miles of sewer per year.
All spills were mitigated in a timely manner and had no negative impact to public health or the environment. The City of Simi Valley is not responsible for service laterals. Property owners are responsible for the installation, maintenance, and repair of service laterals from the building to the City’s mainline sewer.

18 Element 3 Legal Authority
SSS WDR Requirement:
Each Enrollee must demonstrate, through sanitary sewer system use ordinances, service agreements, or other legally binding procedures, that it possesses the necessary legal authority to:
a) Prevent illicit discharges into its sanitary sewer system (examples may include I/I, storm water, chemical dumping, unauthorized debris and cut roots, etc); b) Require the sewers and connections to be properly designed and constructed; c) Ensure access for maintenance, inspection, or repairs for portions of the lateral owned or maintained by the Public Agency;
d) Limit the discharge of fats, oils, and grease and other debris that may cause blockages and
e) Enforce any violation of its sewer ordinances.
The City’s legal authority to prevent illicit discharges, require proper design and construction of sewers and connections, and require proper installation, testing, and inspection of sewers is provided in the Sewer Use Ordinance No. 1170 adopted on March 21, 2011.
3. A Illicit Discharge Prevention
The Sewer Use Ordinance No. 1170 and Enforcement Response Plan provide authority to prevent illicit discharges into the City’s sanitary sewer system.
The Ordinance sets forth uniform requirements for direct and indirect use of the wastewater collection and treatment system of the City of Simi Valley (City) to comply with all applicable State and Federal standards required by the Clean Water Act of 1977 (ACT), and all related and applicable Federal regulations and grant conditions, as they are now constituted, or as they may hereafter be amended or re-codified.
The Enforcement Response Plan (ERP) outlines operational procedures intended to ensure industrial users, and the small commercial/industrial dischargers to the City’s sanitary sewer system are appropriately permitted and monitored. The Environmental Compliance Division (ECD) administers the ERP. To assure compliance by these dischargers, the ECD i mplements enforcement procedures specified by the U.S. Environmental Protection Agency (EPA) in accordance with 40CFR 403.5 (a), (b) and (c). The ERP specifies criteria by which ECD personnel determine the enforcement action most appropriate to the nature of the violation.
19 3.B Proper Design and Construction Requirements
The City adopted Sewer Use Ordinance No. 1170 on March 21, 2011 regulating and controlling sewage, liquid waste, process and industrial wastewater discharges and provides the authority to establish sewer standards and connection requirements. The Manual and Standard Plans for the Design and Construction of Sanitary Sewerage Facilities (Sewer Manual) establishes uniform policies and procedures for the design and construction of sanitary sewerage facilities operated by the City . The Manual identifies facilities within the City ’s jurisdiction that require review and City approval.
Applicable codes and polic ies are outlined in Section 1.6 of the Sewer Manual. Ordinances, policies, requirements, and standards adopted by the City and within its service area shall be used in the design and construction of sewers. Such requirements include but are not limited to the latest edition of the following:
▪The Uniform Building Code as amended by the local authorities ▪The Uniform Plumbing Code as amended by the local authorities ▪Road Encroachment Regulations of the City and the County of Ventura. ▪State Standard Specifications
▪Manual & Standard Plans for the Design Construction of Sanitary Sewerage Facilities. ▪Road Standards for the City and the County of Ventura. ▪Standard Specifications for Public Works Construction. ▪Storm water Ordinance No. 1195
▪Recycled Water Standards, City of Simi Valley Waterworks District No.8. ▪Water Standards, City of Simi Valley Waterworks District No.8.
Public/Private sewage disposal requirements are addressed in Section 1.7 of the Sewer Manual.
A public sewer connection is required if any one of the following conditions exists:
The City or County Health Department declares a private disposal facility within the City sewer service area to be a public nuisance or health hazard.
Septic tank system fails and needs replacement and a public sewer is available within 200 feet.
20 All new tract residential or commercial developments.
All individual single-family lot developments, except where the property line is more than 200 feet away from the closest point of connection.
Connections of any cesspool seepage pit, septic tank or any other private disposal system to any sewer main line or service lateral is strictly prohibited.
The City must approve all design plans and specifications of all wastewater facilities within the public right-of-way and on easements to assure all designs and final construction adhere to t he City’s design and construction standards as outlined in the Sewer Manual.
Sewer Lateral Policy
This Sewer Lateral Policy establishes various criteria and verification procedures necessary for the City to ascertain whethe r plumbing expenses for the sewer lateral line repairs are reimbursable to the property owner. The lateral consists of two adjoining segments as shown in Figure 5-1; the upper lateral on private property from the building to the right -of-way, and the lower lateral from the right-of-way to the public sewer main.
The public sewer main is owned and maintained by the City. However, the connecting sewer lateral line from the house/building to the sewer main in the street is owned and maintained by the property owner. It is the responsibility of the property owner to properly maintain the sewer lateral line. Internal problems in the sewer lateral line, such as internal blockages, misalignments, or deterioration, are the property owner’s responsibility.
3.C FOG and Debris Discharge Prohibitions
The Sewer Use Ordinance No. 1170 provides Environmental Compliance the following authority to require interceptors:
Restaurants: All restaurants or other similar establishments discharging grease wastes which, under the conditions existing in the downstream sewers, could cause or threaten to cause stoppage or grease accumulations, shall be required to install an approved interceptor and to regularly maintain it so as to prevent excessive discharges of fats, oils and grease into the sewerage system. The interceptor shall be easily accessible for inspection by the City.
Exceptions to the installation of an interceptor shall be determined on a case -by-case basis by the City.
Car Washes, Vehicle Service Stations and Garages: A ll new car washes, vehicle service stations and garages which have facilities for the wash down of vehicles shall install an appropriate sand and oil interceptor of a size and design approved by the City. 21 Establishments in existence prior to the effective date of Ordinance No. 1170 shall install appropriate sand and oil interceptor, if in the opinion of the City, the establishment has the potential of contributing non-compatible materials to the sewerage system.
Existing Interceptors: An interceptor legally and properly installed at a vehicle service station, garage, car wash, restaurant or similar establishment prior to the effective date of the Sewer Use Ordinance No. 1170 shall be acceptable as an alternative to the interceptor specified in Subsections (1) and (2) of Section 604 provided such interceptor is effective in removing sand, oil and grease and is so designed and installed so that it can be inspected and properly maintained. If the City determines that an interceptor is incapable of adequately re taining the sand, oil, or grease in the wastewater flow from a service station, garage, car wash, restaurant or similar establishment, a written notice shall be issued requiring that an adequate interceptor be installed within ninety (90) days.
Approved In terceptor Designs : Interceptors shall exceed a recommended minimum size standard of 750 -gallon capacity except when a variance is granted, in writing, by the City.
Existing facilities may apply for a sizing variance to a recommended minimum 70 -pound capacity interceptor. The City of Simi Valley Environmental Compliance Division maintains an information file, available for public use, of acceptable designs of interceptors. The installation of an interceptor of standard design meeting the requirements set forth in Section 604 of Ordinance No. 1170 or any recommendation or requirements made by the City, shall not impute any liability to the City for the adequacy of the interceptor under the actual conditions of use. A civil engineer registered in the State of California shall design the installation of the interceptor; such installation shall not relieve the owner or proprietor of the responsibility for keeping sand, oil and grease out of the sewer. If the interceptor is not adequate under the conditions of use, one shall be constructed which is effective in accomplishing the intended purpose.
Variances on Interceptor Sizing: An interceptor sizing variance may be granted by the City when the following conditions are met:
The discharger applies for the variance, in writing, including the volume of all fixtures required to be pretreated by the unit.
Where a variance is sought for an under the counter interceptor, no garbage disposals, dishwashers, floor sinks or floor drains exist at the facility which require pretreatment by the unit.
The sizing variance is calculated based on the discharge flow rate of all fixtures required to be pretreated and is certified by a civil engineer registered in the State of California.
22 Maintenance of Interceptors: Any interceptor required by Ordinance No. 1170 Section 604 shall be readily accessible for inspection and properly maintained to assure that the accumulations of sand, oil and grease do not impair the efficiency of the interceptor to prevent discharges of sand, oil and grease into the sewerage system. All locations required to use and maintain an interceptor shall keep a record of every time the interceptor is cleaned out. This record shall include the date, the name of the pumper or person who cleaned it and the disposal site of the waste. This record may be reviewed by the City at its option. Persons hauling liquid wastes removed from interceptors shall be registered to do so by the State of California in accordance with the California Administrative Code, Title 23, Waters, Chapter 3; Subchapter 1 and as called out in Section 512 of Ordinance No. 1170. An interceptor shall not be considered properly maintained if sand, oil and grease accumulations total more than twenty-five percent (25%) of the operative fluid capacity. The City Environmental Compliance Division shall routinely inspect all interceptors within its jurisdiction. If it is found that an interceptor is improperly maintained or adequate records are not being kept, a warning will be issued to the owner and/or user of the property. If on subsequent inspections, it is found that one of the above conditions continues to exist, an administrative liability as set by the City will be levied against the facility owner and/or user of the property.
3.D Sewer Ordinance Enforcement
Title 1, Chapter 2 of City of Simi Valley Municipal Code provides the Environmental Compliance Division authority to enforce code violations and the Sewer Use Ordinance No. 1170
23 This Sewer Lateral Policy establishes various criteria and verification procedures necessary for the City to ascertain whether plumbing expenses for the sewer lateral line repairs are reimbursable to the property owner.
The main public sewer line in the street is owned and maintained by the City. However, the connecting sewer lateral line running from the house/building to the main sewer line in the street is owned and maintained by the property owner. It is the responsibility of the property owner to properly maintain the sewer lateral line. Internal problems in the sewer lateral line, such as internal blockages, misalignments, or deterioration, are the property owner’s responsibility.
Tree roots themselves are not generally able to penetrate a properly maintained sewer lateral line without a pre- existing entryway. Inferior materials, poor installation and/or maintenance may cause the sewer lateral line and/or seals to decay, disintegrate or otherwise deteriorate, loosen joints, develop fissures, spaces, openings, and/or other potential entryways for tree roots: such entryways may leak and discharge sewage into the ground, in violation of the City of Simi Valley Municipal Code, Section 6-6.06.
If a property owner believes that roots from a City -owned tree may have caused damage to a properly maintained and sealed private sewer lateral line, and wishes to be reimbursed for the necessary repair/replacement work, the property owner must complete the following steps so that the City may investigate, verify the facts, and evaluate the circumstances:
24 1. Whether the private sewer line lateral repair or replacement work is to be done within private property (Upper Lateral) or public right-of-way (Lower Lateral), the property owner or contractor must contact the City of Simi Valley Sanitation Division at (805) 583- 6440, 24-hours prior to any work, for the City’s inspection of the roots and sewer lateral line. If this step is not followed, the City’s staff will be unable to confirm the cause of the problem, and the property owner will not receive reimbursement consideration.
2. If sewer lateral line repair/replacement work is to be done within the public right -of-way, the property owner’s A-licensed contractor must first obtain an Encroachment Permit from the Public Works Department by calling (805) 583-6786.
3. All sewer lateral line work must follow the City’s guidelines for evacuation, including the City’s “Procedures for Trenching or Construction Near Trees” available through the Public Works Department.
4. The property owner’s contractor must, in the presence of the City Inspector(s), uncover the sewer lateral line, not removing it or any roots, in order to allow for proper inspection and tracing of tree roots. The City Inspector(s) will check the sewer lateral line for its condition; including whether improperly sealed or failed joints, pipe damage or deterioration have caused root entryways. The inspection will also include review of the type and age of pipe materials, the proper installation and maintenance, and whether earthquake movement may have damaged the sewer lateral line or otherwise caused root entryways, as the City is not responsible for the consequences of earthquakes or sewer lateral line deterioration.
5. In the event that the City Inspector determines that a City-owned tree has caused damage to an otherwise properly maintained and sealed sewer lateral line, the City will request a reasonable cost estimate from a qualified and appropriately licensed, insured, and bonded contractor, for the repair work. The City will consider reimbursement for only that portion of the sewer lateral line repair work damaged by City property.
WHERE THERE IS NO INSPECTION, THERE IS NO REIMBURSEMENT! However none of the above is intended to preclude the property owner or contractor/plumber from cleaning the sewer lateral line to reestablish drainage. Should you have any questions or need further assistance, please call (805) 583-6440.

25 Element 4 Operation and Maintenance Program
SSS WDR Requirement:
The SSMP must include those elements listed below that are appropriate and applicable to the Enrollee’s system:
A) Maintain an up to date map of the sanitary sewer system, showing all gravity line segments and manholes, pumping facilities, pressure pipe and valves, and applicable storm water conveyance facilities;
B) Describe routine preventive operation and maintenance activities by staff and contractors, including a system for scheduling regular maintenance and cleaning of the sanitary sewer system with more frequent cleaning and maintenance targeted at known problem areas. The preventative Maintenance (PM) program should have a system to document scheduled and conducted activities, such as work orders; C) Develop a rehabilitation and replacement plan to identify and prioritize system deficiencies and implement short term and long term rehabilitation actions to address each deficiency. The program should include regular visual and T V inspections of manholes and sewer pipes, and a system for ranking the condition of sewer pipes and scheduling rehabilitation. Rehabilitation and replacement should focus on sewer pipes that are at risk of collapse or prone to more frequent blockages due to pipe defects. Finally, the rehabilitation and replacement plan should include a capital improvement plan that addresses proper management and protection of the infrastructure assets. The plan shall include a time schedule for implementing the short and long term plans plus a schedule for developing the funds needed for the capital improvement plan;
D) Provide training on a regular basis for staff in sanitary sewer system operations and maintenance, and require contractors to be appropriately trained; and E) Provide equipment and replacement part inventories, including identification of critical replacement parts.
4.A Map of the Sanitary Sewer System
The City maintains comprehensive maps of its collection system in an electronic format, linked to a database through a geographic information system (GIS). The linked GIS database contains the following additional information for manholes, pipes and pump stations. The City’s GIS has developed a separate layer showing the locations of storm drains. City engineerin g staff enters as built plan information on an ongoing basis into the GIS database. 26 Map of Sewer Lines

27 4.B Preventive Operation and Maintenance Program
The City has a preventive maintenance program based on its experience with spills and sewer service calls. This program also identifies problem sewer mains that cause accumulation of debris and grease. Pipe segments are identified by upstream and downstream manhole identification numbers. The collection crew goes out with a Line Maintenance Daily sheet, after cleaning a line segment it is inputted onto the sheet. After returning from the day’s work the line segments are captured into the GIS database.
Sewer Main Cleaning
The City conducts regular cleaning and maintenance of its 380 miles of mains, with more frequent cleaning in priority areas based on specific cleaning needs. The frequencies for priority areas range from quarterly to yearly. Over all system is to be cleaned within a three year range.
Cleaning is accomplished using the City’s two Vactors (Combination Hydroflusher and Vacuum Truck) and one Hydroflusher. The City typically cleans all of its sewer mains ranging from 6” to 48”.
28 Pump Station Preventive Maintenance
There are three pump stations in the City’s collection system (Big Sky, Wood Ranch, and Arroyo).
The pump stations are all connected to Mission Dialogic.
City staff maintains pump station reliability by performing weekly rounds and ongoing maintenance of the pump station components and generator for power outages.
QA/QC
The City implements a QA/QC program. In this program the Collection Supervisor provides feedback to the cleaning crews to support modification of the cleaning process, practices, techniques and tool use to improve line cleaning quality. Feedback is usually provided in staff meetings and one on one meetings with employees.
4.C Rehabilitation and Replacement Plan
Over the past several years, the City has completed various sewer rehabilitatio n projects and maintains a list of identified sewer rehabilitation needs.
29 A sewer trunk r ehabilitation-replacement p lan incorporates the findings of a comprehensive inspection of the system and identifies defects utilizing standardized manhole and pipe inspection logs. NASSCO rating system is utilized for rating defects within the pipeline. Each pipe segment and manhole is assigned a facility identification number and once inspected is then assigned a NASSCO rating score that includes factors for the probability of failure and the criticality of the asset risk assessment. Pipes and manholes are categorized in the rehabilitation- replacement plan which evaluates the appropriate action needed, the anticipated cost , and a schedule for implementation.
The i nformation collected through CCTV inspection provides the basis for identifying system needs and develops priorities and schedules for projects that are incorporated into the City Wastewater Capital Improvement Program.
Sanitation projects represent three categories of capital improvements:
Facilities Replacement
Sewer Line Rehabilitation and Replacement
Expansion/Upgrade the City Sanitation System.
Rehabilitation and replacement projects are financed from Sanitation operation fund revenue from special assessments and sewer service charges collected from sewer customers. Expansion and upgrade projects are financed from connection fee revenue generated by new development .
Capital improvement projects costs are projected and each fiscal year funding is authorized by City Council as part of the overall Sanitation Budget.
CCTV Inspections
The City conducts CCTV line inspections on a nearly daily basis. Inspections occur before or after the following activities:
Collection system engineering projects: Video inspections occur as a part of engineering projects, including for the capital improvement program.
Emergency calls:
Video inspections provide important information for sewer line emergencies. For instance, staff can perform a CCTV inspection on a main line that was 30 plugged to determine the cause of the blockage. Both the onsite crew and the Collection Supervisor can investigate the cause and determine the need for preventive maintenance and repair.
Food Service Establishment (FSE) Areas: The City televises all main line and lateral connections in the vicinity of food service establishments.
As-Needed: If other reasons indicate that CCTV are needed, a crew is sent to the scene to collect the information.
Asset Management: Asset management activities for CCTV line inspections are conducted to maintain an appropriate level of effort and resources for condition assessment of assets.
Condition Assessment: The City dedicates one crew to the pipeline CCTV inspection program. The City’s mainline sewer condition assessment program includes CCTV inspection of main line pipes to determine their condition and to identify cleaning issues. The City also follows up all SSOs with video inspections. Using the industry- standard National Association of Sewer Service Companies (NASSCO) Pipeline Assessment and Certification Program (PACP), all structural and O&M defects discovered in main lines are assigned a condition grade from 1 to 5. NASSCO provides the following general guidelines to aide in the interpretation of PACP condition grades • PACP Structural Grade 5 – has failed or is likely to fail in five years • PACP Structural Grade 4 – likely to fail in 5 to 10 years • PACP Structural Grade 3 – may fail in 10 to 20 years
• PACP Structural Grade 2 – unlikely to fail for at least 20 years • PACP Structural Grade 1 – failure unlikely in the foreseeable future CCTV inspections are recorded and stored in the City’s servers. The Collection System Supervisor reviews PACP coding of video inspection results and identifies and prioritizes system deficiencies to assist the Engineering department in development of short and long term plans for rehabilitation of the collection system.
CCTV Inspection
31 Capital Improvement Plan
The City updates its Capital Improvement Plan (CIP) annually, to ensure proper management and protection of infrastructure assets. The CIP is developed for each fiscal year. Element 8 of this SSMP provides additional details for short and long term projects.
4.D Training
Employees receive annual SSO training to comply with the requirements of the State Waste Discharge Requirements (WDR). This training involved both classroom and practical scenario based training in the response, mitigation, and reporting of overflows. The recurrent training will cover any updates/changes to documentation and/or process since the most recent training event. Training is provided by in-house supervisory staff that have been qualified to provide overflow training.
The City uses a combination of on-the-job training, conferences, seminars, and other training opportunities to provide technical training for its wastewater collection system staff. Vendors provide training for new tools or equipment.
32 The Collections crew receives regular training on the following topics: volume estimation, storm water pollution prevention, confined space entry, biological and chemical hazards, Combination cleaning machine, jetter, underground construction, gas detector use, back injury prevention, overflow reporting and field documentation, and the content and procedures of the SSMP.
4.E Equipment and Replacement Part Inventories
The City uses the following major equipment for its sewer system O&M:
Combination Cleaning/Vacuum Trucks (2): The combination vacuum/jetter trucks are used for regular sewer line maintenance. The City also uses a high-volume vacuum to remove broken up grit and debris. The 1” hose can deliver a high-pressure spray to effectively break up blockages in sewer lines and flush out debris. This type of truck is also used for hydro- excavation.
Jetter Truck: The Jetter truck is used for regular sewer line maintenance cleaning. The ¾” hose delivers a high pressure spray to effectively break up blockages in the sewer lines and flush out the debris.
Easement Machine: The Ramvac Stanley Easement Machine is used to assist cleaning sewer lines in easement locations. The ¾” hose delivers a high pressure spray to effectively break up blockages in the sewer lines and flush out the debris. The machine is connected to the ¾” hose of the Jetter truck.
CCTV Truck: CCTV is the cornerstone of the condition assessment portion of the City’s asset management program. Each camera on a TV truck is deployed into the sewer to look for sewer line integrity issues such as roots intruding into the pipe, cracked or broken lines, and offset joints or pipes. The video information is transmitted real-time to a screen in the TV Truck, and is also recorded digitally for future reference. Pipe segments and manholes are thoroughly viewed, commented on, and coded.
Envirosight Quickview 360 Manhole Camera: Quickview 360 is designed with twin cameras for 360-degree footage and a rangefinder for rapid guided descent and precision measurement. Maneuverable pan/tilt controls are fed directly from your hand- held app through Wi-Fi, and a smooth, telescopic pole makes for quick ascent so you can keep moving to the next manhole.
Envirosight Zoom Pole Camera: Quickview app-based touchscreen controls wirelessly operate camera zoom and tilt, adjust illumination, overlay text, view live and recorded video

38 1. Purpose
The purpose of Simi Valley Spill Emergency Response Plan (SERP) is to support a prompt, orderly and effective response to spills (sanitary), reduce spill volumes, and collect information for prevention of future spills. A “spill” in this document is defined, by State Water Board No. WQ 2022- 0103-DWQ as 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.
The SERP provides guidelines for city personnel to follow in responding to, cleaning up, reporting, and properly documenting spills that ma y occur within the City of Simi Valley’s service area. This SERP satisfies the State Water Board Order No. WQ 2022-0103-DWQ, which require wastewater collection agencies to have a Spill Emergency Response Plan.
2.Policy
The city of Simi Valley employees are required to report all spills from city owned sewer mains found and to take the appropriate action to secure the spill area, properly report to the appropriate regulatory agencies, relieve the cause of the spill, and ensure that the affected area is cleaned as soon as possible to minimize health hazards to the public and protect the environment. The City of Simi Valley’s goal is to respond to sewer system spills as soon as possible following notification. The city will follow reporting procedures regarding sewer spills as set forth by the Los Angeles Water Quality Control Board and the State Water Board order No. WQ 2022-0103-DWQ (SSSWDR).

6. Spill Detection and Notifiacation
Ref. State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR), Attachment D, Element 6, Page D-6 The processes that are employed to notify the city of the occurrence of a spill include: observation by the public, receipt of an alarm, or observation by City staff during the normal course of their work.
6.1 Lift Station Alarms
The city operates 3 wastewater liftstations. In the event of a station fa ilure the Dialogic alarm system is activated and the City is contacted. To prevent spills, wastewater from the wet well can be pumped into a vacuum t ruck for disposal to a nearby sanitary sewer manhole or bypassed around the station into the sanitary sewer system.
6.2 Public Observation
Public observation is the most common way that the city is notified of blockages and spills.
Contact numbers and information for reporting sewer spills and backups are on e the city website; https:// simivalley.org. The cityies telephone number is 805 -583-6400 and direct to Sanitation is 805-583-6440
● Normal Work Hours: When a report of a sewer spill or backup is made during work hours city hall receives the call. City hall will transfer the call to Sanitation. ● After Hours: After hour calls will be answered by the standby service who will call th e on call employee. The standby service will follow the phone tree until an employee is reached.
When calls are received, either during normal work hours or after hours, the individual receiving the call will collect and include in the spill event file, at a minimum, the following information to record the spill. ● Date, time, and method of notification,
● Date and time the complainant first noticed the spill, if available, ● Narrative description of the complaint, including any information the caller provided regarding whether the spill has reached surface waters or a drainage conveyance system, if available, ● Complainant’s contact information, if available, and ● Final resolution of the complaint.
45 6.3 City Staff Observation
City staff conducts periodic inspections of its sewer system facilities as part of their routine activities. Any problems noted with the sewer system facilities are reported to appropriate city staff that, in turn, responds to emergency situations. Work orders are issued to correct non emergency conditions.
6.4 No Observation
If there are no witnesses or no call was received for a spill, the city staff will contact nearby residences or business owners in the vicinity of the spill, in an attempt to obtain information that brackets a given start time that the spill began.

●Properly document the spill and response activities on the forms provided in the Sanitary Sewer Spill Response packet, including photos and video where practicable. 46 7.3 Safety
The first responder is responsible for following safety procedures at all times. Special safety precautions must be observed when performing sewer work. There may be times when City personnel responding to a sewer system event are not familiar with potential safety hazards peculiar to sewer work. In such cases it is appropriate to take the time to discuss safety issues, consider the order of work, and check safety equipment before beginning response activities.
If the first responders encounter access restrictions or unsafe conditions that prevent its compliance with spill response requirements or monitoring requirements in this General Order, the City of Simi Valley provides documentation of access restrictions and/or safety hazards in the corresponding required report.
7.4 Initial Response
The first responder must respond to the site of the spill/backup and visually check for potential sewer stoppages.
The first responder will:
● Note arrival time at the site of the spill/backup.
● Verify the existence of a public sewer system spill or backup. ● Identify and assess the affected area and extent of spill. ● Assess the spill location(s) and spread using photography, global positioning system (GPS), and other best available tools.
● Contact caller
● Document the spill according to the requirements described in Section 10 of this SERP, including taking photos and/or videos of overflowing manhole(S)/Cleanout(S). ● Take steps to contain, recover, and return the spill to the sanitary sewer as feasible. ● Protect surface waters to the extent practicable.
● Implement pre-planned coordination and collaboration with Simi Valley Streets Storm Drain Department or/and Ventura County Watershed prior, during and after a spill event.
7.5 Initiate Spill Containment Measures
The first responder will attempt to contain as much of the spilled sewage as possible using the following steps:
● Determine the immediate destination of the overflowing sewage. ● Attempt to stop the flow of sewer from entering the storm drain. ● Contain/direct the spilled sewage using dike/dam or sandbags ● Vacuum retrieve sewage whenever practicable.
● Pump around the blockage/pipe failure
Containment effeorts will be documented.
7.6 Restore Flow
Using the appropriate cleaning equipment, set up downstream of the blockage and hdro -clean upstream form a clear manhole. Attempt to remove the blockage from the system and observe the flows to ensure that the blockage does not reoccur downstream. If the blockage cannot be 47 cleared within a reasonable time from arrival, or seweer requires construction repairs to restore flow, then initiate containment and/or bypass pumping. If other assistance is required, immediatel contact Collections Supervisor and Deputy Director of Sanitation.
7.7 Equipment
This section provides a list of specialized equipment that may be used to support this Spill Emergency Response Plan.
● Combination Sewer Cleaning Trucks—Combination high velocity sewer cleaning trucks with vacuum tanks are required to clear blockages in gravity sewers, vacuum spilled sewage, and wash down the impacted area following a spill event. ● Sewer Cleaning Truck—High velocity sewer cleaning truck used to clear blockages and wash down the impacted area following a spill event.
● Closed Circuit Television(CCTV) Inspection Truck—A CCTV Inspection truck is required to determine the root cause for all spills from gravity sewers. ● Emergency Response Truck—A utility body pick up truck, to store and transport the equipment needed toeffectively respond to sewer emergencies. ● Portaable pump—Equipment used to bypass, divert, a sewer spill.
8. Recovery and Cleanup (Ref. State Water Board Order No. WQ 2022 -0103-DWQ (SSSWDR), Element 6 Attachment D, Page D-6)
The recovery and cleanup phase begins immediately after the flow has been restored and the spilled sewage has been contained to the extent possible. The spill r ecovery and cleanup procedures are described in the following sections.
8.1 Estimate The Flow and Volume of Spilled Sewage
A variety of approaches exist for estimating the volume of a sanitary sewer spill. The Collections crew members should use the method most appropriate to the sewer overflow in question. ● Eyeball Estimation Method
● Duration and Flow Rate Calculation Method
● Area/Volume Method
● Upstream Connections Method
In addition, the following will be documented on the Sewer Spill Report form:
1. Description, photographs, and GPS coordinates of the system location where the spill originated. If a single spill event results in multiple appearance points, provide GPS coordinates for the appearance point closest to the failure point and des cribe each additional appearance point in the spill appearance point.
2. Estimated total spill volume exiting the system;
3. Description and photographs of the extent of the spill and spill boundaries.
4. Did the spill reach a drainage conveyance system? If yes:
● Description of the drainage conveyance system transporting the spill; ● Photographs of the drainage conveyance system entry location(s); ● Estimated spill volume that reached the drainage conveyance system; ● Estimated spill volume fully recovered from the drainage conveyance system; ● Estimated spill volume remaining within the drainage conveyance system; 48 ● Estimated spill volume discharged to a groundwater basin or facility, if applicable;
● Estimated spill travel time from the point of entry into the drainage conveyance system to the point of discharge into the receiving water.
5. Estimated total spill volume recovered.
8.2 Recovery of Spilled Sewage
Vacuum up and/or pump the spilled sewage and wash down water and discharge it back into the sanitary sewer system. Thoroughly recover and dispose of sewage and wash down water.
8.3 Clean Up and Disinfection
Clean up procedures will be implemented to reduce the potential for human health and adverse environmental impacts associated with a spill event. The procedures described are for dry weather conditions and will be modified as required for wet weather conditions. Where cleanup is beyond the capabilities of City staff, a cleanup contractor may be used.
Hard Surface Areas
Collect all signs of sewage solids and sewage related material either by protected hand or with the use of rakes and brooms. Wash down the affected area with clean water. The flushing volume will be approximately three times the estimated volume of the spill. Take steps to contain and vacuum up the wastewater. Allow the area to dry. Repeat the process if additiona l cleaning is required.
Landscaped and Unimproved Natural Vegetation
Collect all signs of sewage solids and sewage related material either by protected hand or with the use of rakes and brooms. Wash down the affected area with clean water. The flushing volume will be approximately three times the estimated volume of the spill. Take steps to contain and vacuum up the wastewater. Allow the area to dry. Repeat the process if additional cleaning is required.
Natural Waterways
The Department of Fish and Wildlife will be notified by Cal OES and City of Simi Valley Environmental Compliance for spills greater than or equal to 1000 gallons. For spills less than 1000 gallons contact the City of Simi Valley Environmental Compliance and the Ventura County Health Department for direction.
Wet Weather Modifications
Collect all signs of sewage solids and sewage related material either by protected hand or with the use of rakes and brooms. Omit flushing and sampling during heavy storm events (i.e. sheets of rainwater acro ss paved surfaces) with heavy runoff where flushing is not required and sampling would not provide meaningful results.
49 8.4 Public Notification
Signs will be posted and barricades put in place to keep vehicles and pedestrians away from contact with spilled sewage. Ventura County Environmental Health Department instructions and directions regarding placement and language of public warnings will be followed. Additionally, the Collections Supervisor will use their best judgement regarding supplemental sign placement in order to protect the public and local environment. Signs will not be removed until directed by the Ventura County Health Department.
Creeks and streams that have been contaminated as a result of a spill will be posted at visible access locations until the risk of contamination has subsided to acceptable background bacteria levels. Document the number and location of posted signs. The area and warning sign, once posted, will be checked every day to ensure that they are still in place. Photographs of sign placement will be taken.
In the event that an overflow occurs at night, the location will be inspected first thing the following day. The field crew will look for any signs of sewage solids and sewage related material that may warrant additional cleanup activities.
When contact with the local media is deemed necessary, the Public Works Director or their designee will provide the media with all relevant information.
9. Surface Waters of Concern
● Arroyo Simi
For sewage spills in which an estimated 50,000 gallons or greater are discharged into a surface water, the City will conduct the following water quality sampling as soon as possible but no later than 18 hours after the city’s knowledge of a potential discharge to a surface water, Collect one water sample, each day of the duration of the spill at; ● The DCS-001 location as described in section 9.7 (Receiving Water Sampling Locations) below, if sewage discharges to a surface water via a drainage conveyance system; and/or ● Each of the three receiving water sampling locations in section 9.7 (Receiving Water Sampling Locations) below;
If the receiving water has no flow during the duration of the spill, the city must report “No Sampling Due To No Flow” for its receiving water sampling locations.
The Environmental Compliance Staff will collect the samples with a complete Chain of Custody prior to transferring the samples to the Sanitation laboratory.
The city of Simi Valley Laboratory shall analyze the collected receiving water samples for the following constituents:
● Ammonia, and
● Appropriate bacterial indicator(s) per the applicable Basin Plan water quality objectives, including one or more of the following from the table below, unless directed otherwise by the Regional Water Board.
●Total Coliform Bacteria
●Fecal Coliform Bacteria
50 ●E-Coli
●Enterococcus
Dependent on the receiving water(s), sampling of bacterial indicators shall be sufficient to determine post spill (after the spill) compliance with the water quality objectives and bacterial standards of the California Ocean Plan, or the California Inland Surface water Enclosed Bays, and Estuaries Plan, including the frequency and/or number of post spill receiving water samples as may be specified in the applicable plans.
The City shall collect and analyze additional samples as required by the applicable Regional Water Board Executive Officer or designee.
9.3 Lab Selection
Analytical lab
Samples collected for spill response and background monitoring purposes will be analyzed at the City of Simi Valley Sanitation laboratory, which is accredited through the California State Water Resources Control Board Environmental Laboratory Accreditation Program (ELAP). ELAP provides evaluation and accreditation of environmental testing laboratories to ensure the quality of analytical data used for regulatory purposes to meet the requirements of the State’s drinking water, wastewater, food and hazardous waste programs. The State agencies that monitor the environment use the analytical data from these accredited labs. The ELAP accredited laboratories have demonstrated capability to analyze environmental samples using approved methods.
Once samples are collected, they will be transported by Environmental Compliance Inspectors to the lab to be processed.
9.4 Water Quality Analysis Specifications
Spill monitoring must be representative of the monitored activity (40 Code of Federal Regulations section 122.41 (j)(1)).
Sufficiently Sensitive Methods
Sample analysis must be conducted according to sufficiently sensitive test methods approved under 40 Code of Federal Regulations Part 136 for the sample analysis of pollu tants. For the purposes of this General Order, a method is sufficiently sensitive when the minimum level of the analytical method approved under 40 Code of Federal Regulations Part 136 is at or below the receiving water pollutant criteria.
Environmental Laboratory Accreditation Program-Accredited Laboratories The analysis of water quality samples required per this General Order must be a laboratory that has accreditation pursuant to Article 3 (commencing with section 100825) of Chapter 4 of Part 1 of Division 101 of the Health and Safety Code. (Water Code section 13176(a)). The State Water Board accredits laboratories through its Environmental laboratory Accreditation Program (ELAP).
51 9.5 Receiving Water Sampling Locations
The City shall collect receiving water samples at the following locations.
Sampling of Flow in Drainage Conveyance System (DCS) Prior to Discharge
Sampling Location Sampling Location Description
DCS-001 A point in a drainage conveyance system before the drainage Conveyance system flow discharges into a receiving water.
Receiving Surface Water Sampling (RSW)
Sampling Location Sampling Location Description
RSW-001: A point in the receiving water where sewage initially enters RSW-001D: A point in the receiving water, downstream of the point of sewage discharge,
Where the spill material is fully mixed with the receiving water.
9.7 Sample Types
Grab Samples
Grab samples are appropriate for the characterization of surface waters at a particular time and place, to provide information about minimum and maximum concentrations, and to allow for the collection of variable sample volume.
Grab samples may be collected directly into the sample container, or a clean decontaminated intermediate container may be used if a wading sample is not possible or safe. If an intermediate container is used, when in the field, double rinse the sampling device (bucket, automatic sampler) with sample water prior to collecting the sample and be sure to discard rinse water downstream of where sample will be collected. If samples are collected in a bucket and d istributed a consolidation collection container, swirl the contents of the bucket as it is being poured into the consolidation collection container to avoid settling of solids (and pour in back and forth pattern – e.q., 1-2-3-3-2-1).
●Grab Sample: A grab sample is defined as an individual sample collected at a given time.
Grab samples represent only the condition that exists at the time the sample is collected (US EPA 1977).
●Surface Grab Sample: A sample collected at the water surface (i.e., skimming) directly into the sample container or into an intermediate container such as a clean bucket. A single or discrete sample collected at a single location.
Field Blanks
Field Blanks are used to elevate the potential for contamination of a sample by site contaminants from a source not associated with the sample collected (airborne, dust etc.) Sterile, deionized water is taken into the field in a sealed container. This is the stock water. The stock water is then 52 poured into the sample container. The containers and sample submission forms are labeled “Field Blank.” The same template selected for t he test samples should be used. Field blanks are subject to the same holding time limitations as samples. The appropriate Field QC box on the sample Chain of Custody form should be checked.
9.8 Sample Labeling and Chain of Custody Procedures
At a minimum, the following grab samples will be collected, in duplicate:
● Field Blank: See section 9.7 for discussion
● Upstream: A point in the receiving water, upstream of the point of sewage discharge, to capture ambient conditions absent of sewage discharge impacts. ● Source: A point in the receiving water where sewage initially enters the receiving water. ● Downstream of spill: A point in the receiving water, downstream of the point of sewage discharge, where the spill material is fully mixed with the receiving water. This location will vary with the velocity of the surface water to be sampled (See Section 9.6).
Sample labels shall be completed for each sample, using waterproof ink.
Photos or video of each sample location will be taken, properly labeled with date, time, and view direction and a map of the photo locations completed. Photos and videos shall include relevant landmarks to identify sampling locations and their surroundings.
Due to the evidentiary nature of samples collected during enforcement investigations, possession must be traceable from the time the samples are collected until they are analyzed. To maintain and document sample possession, a Surface Water Sample Chain of Custody Record must be completed. A sample is under custody if:
● It is in your possession, or
● It is in your view, after being in your possession, or ● It was in your possession and under your control to prevent tampering, or ● It is in a designated secure area.
As few people as possible should handle samples. The person taking the samples is personally responsible for the care and custody of the samples collected until they are transferred or dispatched properly.
Samples are accompanied by a chain of custody record. When transferring the possession of samples, the individuals relinquishing and receiving will sign, date, and note the time on the record. This record document sample custody transfer from the sampler, often through another person, to the analyst at the laboratory. The samples are typically transferred to the sample receiving custodian at the laboratory.
9.9 Sampling Equipment
The following are examples of sampling equipment used by the City:
●Sampling pole with fixed container
●Sampling pole with removable container
●Sampling Pail and Rope
53 9.10 Decontamination Procedures
Removing or neutralizing contaminants form sampling equipment minimizes the likelihood of sample cross contamination, reduces or eliminates transfer of contaminants to clean areas, and prevents the mixing of incompatible substances.
Gross contamination can be removed by physical decontamination procedures. These abrasive and non-abrasive methods include the uses of brushes, air and wet blasting, and high and low pressure water cleaning.
The decontamination procedures for the sample types and sampling equipment used at the City may summarized as follow:
1. Physical removal
2. Tap water rinse
3. Air dry
9.12 Sampling Procedures
9.12.1 Sample Location and Identification Procedures
Samples will be collected by the Environmental Compliance Department . It is impossible to establish hard and fast rules concerning sampling locations. However, the following general guidelines should be applied whenever surface waters are sampled:
●The sampling location should be far enough upstream or downstream of confluences or point sources so that the surface water and spill volume is well mixed. Natural turbulence can be used to provide a good mixture.
●Samples should be collected at a locatio n where the velocity is sufficient to prevent deposition of solids, and to the extent practical, should be in a straight reach having uniform flow. All flow in the reach should be represented, so divided flow areas should be avoided and samples should be taken towards the middle of the reach where feasible.
●Sampler must always stand downs tream of the collection vessel, and sample “into the current.” Care must be taken to avoid introducing re -suspended sediment into the sample.
9.12.2 Surface Water Sampling Standard Operating Procedure (SOP) The surface water sampling to collect samples and deliver them for analysis in accordance with State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR), Element 6
9.12.3 Follow Up Sampling
Sampling will be repeated every 24 hours, or as Directed by the Ventura County Environmental Health Department, until such time as one of the following criteria have been met:
●The Ventura County Environmental Health Department follow up sampling is no longer required or
●Both the ammonia and bacteria levels downstream are approximately equal to or less than the upstream levels.
54 9.13 Safety and Access Expectations
If the City encounters access restrictions or unsafe conditions that prevents its compliance with spill response requirements or monitoring requirements in this General Order, the City shall provide documentation of access restrictions and/or safety hazards in the corr esponding required report.
Personal safety of staff engaged in any fieldwork activity (e.g. in transit, walking or hiking, and any field activities while at the sample site) is of primary importance. Staff should never place themselves in dangerous or ris ky situations. Any hazards that are known by field personnel should be communicated to other members of the field crew.
Field work should be postponed if there is indication that engagement in the field activity could cause bodily harm. Working during lightning storm, in heavy vegetation or poison oak, near aggressive wildlife or domestic animals, traversing steep or rugged terrain, unstable slopes or creek banks, near swiftly moving water or potential flash flood conditions, or during snow weather is not considered “normal risk.” If any member of the field crew is uncomfortable with a reasonable self-determined hazardous field condition, it is that person’s responsibility to bring this to the attention of the onsite field supervisor or their supervisor. A “reasonable self - determined hazardous field condition” is defined as other than normal risk. Supervisors shall not dismiss any person’s spoken concerns that field conditions are too hazardous to complete the work assignment.
The person taking the samples must have adequate protection, including protective clothing.
They must wear gloves, as protection against chemical and/or bacteriological hazards, while they are sampling or handling samples that are known or suspected to be hazardous (e.g. visible solids,
or sheens, downstream from sewage spills, etc.), or if hands have open wounds. The type of gloves worn shall be determined by the sampling circumstance and type of pollutants expected- for instance longer gloves are needed when samples must be taken well below the surface.
When in boat or wading in a stream and where the danger of drowning exists, a personal floatation device shall be worn at all times in addition to following the other requirements of Title 8 CCR 1602 Working Over or Near Water. Other protective measures shall be taken in accordance with City Safety procedures.
Upon arrival at a sampling site, safety equipment such as cones, signs, lights, etc. shall be set out as appropriate. Vehicles shall be parked in locations and directions to minimize traffic disruption and avoid sample contamination. Photos should be ultimately taken of the placement of all safety equipment and signage.
The following guidelines apply to all field work by City staff. ●No sample or measurement is worth the risk of injury.
●All staff shall use proper personnel protective gear as appropriate for the incident. 55 ●Field sampling crews should consist of at least two members unless otherwise approved by a supervisor.
●Be conscious of the whereabouts of rattlesnakes, mountain lions, and other dangerous animals.
●Open body wounds are entry sites for infection; take the necessary precautions for self- protection.
●If there is storm activity in the work area, wait for safer conditi ons to develop or postpone the sampling.
●Do not sample at night without approval from your supervisor. ●If strange or suspicious looking people are in the work area, either wait for them to leave or postpone the work to a later time. Do not force confrontations with strangers and back away from any confrontations with the public. Be courteous and understanding of public concerns of the situation.
●Take the necessary precautions against exposure to harmful weather conditions such as heat, wind, snow, cold, rain, etc.
●Carefully evaluate a given on site situation to determine if the task can be performed safely.
●Streams will not be entered unless the responding employees have the necessary protective footwear (rubber boots, waders) and the footwear does not pose an additional risk to worker safely.
●Streams will not be entered if deemed unsafe to so by the most senior employee on the responding crew and if entered, will only be done so in accordance with Title 8 CCR Section 1602 Work over or near water.

Each enrollee shall evaluate its service area to determine whether a FOG control program is needed. If an Enrollee determines that a FOG program is not needed, the Enrollee must provide justification for why it is not needed. If FOG is found to be a problem, the Enrollee must prepare and implement a FOG source control program to reduce the amount of these substances discharged to the sanitary sewer system. This plan shall include the following as appropriate:
a) An implementation plan and schedule for a public education outreach program that promotes proper disposal of FOG:
b) A plan and schedule for the disposal of FOG generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of FOG generated within a sanitary sewer system service area:
c) The legal authority to prohibit discharges to the system and identify measures to prevent SSOs and blockages caused by FOG;
d) Requirements to install grease removal devises (such as traps or interceptors), design standards for the removal devices, maintenance requirements, BMP requirements, record keeping and reporting requirements; e) Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the FOG ordinance; f) An identification of sanitary sewer system sections subject to FOG blockages and establishment of a cleaning maintenance schedule for each section; and g) Development and implementation of source control measures for all sources of FOG discharged to the sanitary sewer system for each section identified in (f) above.
7.A Public Education and Outreach Program
The Environmental Compliance Division (ECD) performs the following public education outreach plan:
An outreach program to the residential and commercial community on the proper disposal of FOG: This program includes school handouts, flyers, grease scrapers, and site visits to food service establishments.
Educate residents and food service establishments on the proper disposal of FOG to meet the FOG Control Program requirements set in this Plan.
Conduct a multi -media public awareness and marketing campaign to meet objectives by targeting Simi Valley residents and food service establishments.
The residential campaign provides Best Management Practices (BMPs) for FOG disposal. 62 The food service establishment campaign provides specific FOG reduction information needed to comply with WDR. The messages in this campaign are distributed directly during site visits.
7.B FOG Disposal
The Environmental Compliance Division/Sewer Use Ordinance provides the following FOG disposal criteria for grease interceptors:
The Permittee shall be required to keep all manifests, receipts, and invoices of all cleaning, maintenance, and grease removal from the grease control device, disposal carrier, and disposal site location for no less than three years.
Persons hauling liquid wastes removed from interceptors shall be registered to do so by the State of California in accordance with the California Code of Regulations, Title 23, Waters, Chapter 3; Sub-chapter 1. An interceptor shall not be considered properly maintained if solids, fats, oil, and grease accumulations total more than twenty -five percent (25%) of the operative fluid capacity of the final chamber.
7.C Legal Authority
The Sewer Use Ordinance provides the following authority to require grease interceptors:
All food service facilities discharging grease wastes which, under the conditions existing in the downstream sewers, could cause or threaten to cause stoppage or grease accumulations, shall be required to install an appropriately sized and approved grease interceptor and to regularly maintain it so as to prevent excessive discharges of fats, oil, grease, and solids into the sewerage system.
7.D Grease Trap Requirements
Grease interceptors shall meet or exceed a minimum size standard of 750-gallon capacity, except when a written variance is granted by the City. Facilities may apply for a sizing variance on a case by case basis to a minimum 70-pound capacity grease trap in accordance with this Section.
The design of such installations shall be completed and stamped by a civil engineer registered in the State of California. Such installation shall not relieve the owner or proprietor of responsibility for keeping grease, oil, and solids out of the sew er. If the interceptor or other pretreatment device is not adequate under the conditions of use, one shall be constructed which is effective in accomplishing the intended purpose.
63 7. E Facility Inspections and Enforcement
All food service establishments, or other similar establishments, discharging grease are required to install appropriately sized and approved grease and oil interceptor shall be easily accessible for inspection by the City.
Inspection Reports are completed by the Environmental Compliance Inspectors in the field. The Inspection Report is a permanent record of the meeting between Environmental Compliance staff and the business representative. All relevant information should be documented on the Report, for example, location of grease int erceptor, cleaning schedules, BMPs discussed, etc.
Inspectors use the report for routine inspections, as well as to issue warnings, violation notices, requirements, and follow-up inspection dates.
Maintenance of Interceptors: Any interceptor required by this Section shall be readily accessible for inspection and properly maintained to assure that the accumulations of solids, fats, oil, and/or grease do not impair the efficiency of the interceptor or escape with the effluent. All locations required to use and maintain a grease interceptor shall keep a record of every cleaning/maintenance event. This record shall include the date, the name of the company or person who cleaned it, and disposal site of the waste. This record may be reviewed by the City at its option. Persons hauling liquid wastes removed from interceptors shall be registered to do so by the State of California in accordance with the California Code of Regulations, Title 23, Waters, Chapter 3, Sub-chapter 1. An interceptor shall not be cons idered properly maintained if solids, fats, oil, and grease accumulations total twenty -five percent (25%) or more of the operative fluid capacity of the final chamber. The City will inspect all grease interceptors periodically. If it is found that an interceptor is improperly maintained or adequate records are not being kept, a warning will be issued to the owner and/or user of the property. If on subsequent inspections, it is found that one of the above conditions continues to exist, additional enforcement actions may be taken as outlined in Chapter 9 of the Sewer Use Ordinance 1170 and in the Enforcement Response Plan.
7. F Priority Areas
Collections staff Identify problem areas through CCTV inspection and past spills to create a sewer pipe blockage control program. Issuing work orders for enhanced cleaning cycles of trouble areas.
Review of CCTV footage to identify new portions of the collection system experiencing grease build up or other pipe blocking defects. The Collections Supervisor shall establis h a QA process for evaluating pipe cleaning effectiveness. Inspect assets directly downstream of grease producing business to ensure source control is effective.
64 If build up is found, investigate were the FOG or pipe blocking defect is coming from. If the problem is related to a discharge from a food service establishment or other grease -discharging business, follow the city’s source control procedures to rectify the problem.
7. G Source Control
The Sewer Use Ordinance provides the following record keeping requirements:
All Industrial Users are subject to the Federal Pretreatment Requirements and the Sewer Use Ordinance and are required to retain records of waste manifests, monitoring results, or related wastewater generation, and pretreatment activities , for a minimum period of three (3) years.
Records shall be made available for inspection and copying by the City’s Director at any time. The period of retention shall be extended during the course of unresolved litigation regarding the discharger or the City or upon request of the Director.
All locations required to use and maintain a grease interceptor shall keep a record of every cleaning/maintenance event. This record shall include the date, the name of the company or person who cleaned it, and the disposal site of the waste.
65 Element 8 System Evaluation and Capacity Assurance Plan SSS WDR Requirements:
The Enrollee shall prepare and implement a capital improvement plan (CIP) that will provide hydraulic capacity of key sanitary sewer system elements for dry weather peak flow conditions, as well as the appropriate design storm or wet weather event. At a minimum, the plan must include:
A) Evaluation: Actions needed to evaluate those portions of the sanitary sewer system that are experiencing or contributing to an SSO discharge caused by hydraulic deficiency. The evaluation must provide estimates of peak flows (including flows from SSOs that escape from the system) associated with conditions similar to those causing overflow events, estimates of the capacity of key system components, hydraulic deficiencies (including components of the system with limiting capacity) and the major sources that contribute to the peak flows associated with overflow events;
B) Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation identified in (a) above to establish appropriate design criteria; and C) Capacity Enhancement Measures: The steps needed to establish a short- and long term CIP to address identified hydraulic deficiencies, including prioritization, alternatives analysis, and schedules. The CIP may include increases in pipe size, I/I reduction programs, increases and redundancy in pumping capacity, and storage facilities. The CIP shall include an implementation schedule and shall identify sources of funding.
D) Schedule: The Enrollee shall develop a schedule of completion dates for all portions of the capital improvement program developed in (a)-(c) above. This schedule shall be reviewed and updated consistent with the SSMP review and update requirements as described in Section D. 14
8. A Evaluation
The City of Simi Valley completed its Sewer System Evaluation and Capacity Assurance Plan in August of 2010 by Brown and Caldwell. The report includes information about current and future capacity based on flow monitoring and hydraulic modeling for the collection system. Based on the flow data and rainfall data the City’s collection system experiences a very small amount of I/I even during large storm events. Additionally, observed peaking factors did not vary significantly between dry and wet weather seasons. Based on the observed peaking factors from the historical WWTP flow data, the peaking factor at the system outfall in the hydraulic model should fall
66 between 1.5 a nd 2.5During the we t 2004/2005 winter, nearly 2 MGD of seasonal GWI was observed. The total precipitation during this season was close to the 100 year return period. An average rain year experienced closer to 1 MGD of season GWI. Based on historical spill performance the City does not anticipate capacity failures will drive improvements as much as condition based, given the age and material in the collection system.
8. B Design Criteria
Currently based on historical data we have the capacity to handle peak flows caused by storms.
Currently, Sewage flows shall be determined from maximum potential sewage generation of the tributary area. Average flow rates shall be determined using the designated land use or number of equivalent dwelling units (EDU) assigned. The method which produces the greater rate of flow shall be used as the governing factor. The peak flow rate at any point shall be the average flow of all tributary areas times the peak factor using the Average Flow Peak Flow Graph (Standard Plan No. SV 40-310).
Hydraulics of the sewers shall be designed to accommodate future tributary flows, in addition to those from the project. Pipe capacities shall be determined from peak flow rates by Manning's Formula using an "n" value of 0.011 (or higher when appropriate) for all pipelines. Sewers less than 12 inches in diameter shall be designed to flow half full at peak flow rates. Sewers 12 inches and larger shall be designed to flow two-thirds full at peak flow rate.
When the design involves non-uniform flow, backwater calculations shall be made to the extent necessary to locate hydraulic jumps, to assure that the design depth of flow is not exceeded, and to assure that flow conditions meet all preceding design requirements for the conduit and structures.
The invert drop across junction (confluence) and transition structures shall be calculated and not arbitrarily established. Where calculations indicate a rise of the invert across the structure from the inlet to outlet, the structure shall be designed with the invert level. An additional amount for infiltration shall be added when a sewer is to be constructed below the ground water level. This amount must first be approved by the City. Over sizing of certain tract sewers may be required where such sewers can logically serve an upstream tributary area.
67 8. C Capacity Enhancement Measures
The City includes the identification of short and long-term Capital Improvement Projects (CIP) for interceptor pipelines 8 inches in diameter and greater as part of the “Sewer Collection System Asset Evaluation and Rehabilitation Plan”. This was a condition -based CIP project, but the City has budgeted to supplement that with a capacity-based CIP evaluation also. Based on historical SSO performance the City does not anticipate capacity failures will drive improvements as much as condition-based, given the age and material of pipe in the network.
The television inspection records pipeline condition data pursuant to the National Association of Sewer Service Companies (NASSCO) standard rating system. The program includes manhole condition assessment inspections as well, also conducted pursuant to NASSCO. The condition assessment data gathered and the NASSCO ratings generated during the program are uploaded to the City’s GIS. The data of the pipeline television inspection data with other factors that define each pipeline’s likelihood and consequence of failure. Once compiled, the risk of failure data is used to prioritize defective pipelines, to scope out repair / rehabilitation / replacement projects, and to support preparation of the City’s Capital Improvement Program (CIP) updates. During the District’s CIP update and planning process, condition and capacity -driven pipeline / manhole projects are cross checked for overlap and evaluated for opportunities to improve CIP efficiency and economics. Our current CIP rehabilitation of Asbestos Concrete Pipe using Cured in Place Pipe, will not only repair failing infrastructure but also reduce inflow and infiltration into the collection system.
8. D Schedule
The City’s Capital Improvement Program encompasses all engineered studies and projects related to improvements, repairs, rehabilitation, and replacement of the City’s plant, collection system (includes pump stations and force mains). The 10-year CIP update is a planning tool that manifests proactive asset management, facilitates financial planning (sewer service charges and cash flow), promotes organizational balance (staff’s ability to manage and support the workload), and informs the City Council and the public about the City’s infrastructure needs, upcoming projects, and proposed capital expenditures. Currently we a re working on SLR LA Ave Phase a CIPP of 12” and greater Asbestos Concrete Pipe, and a manhole rehabilitation project the Easy- Arroyo Simi.

69 Element 9 Monitoring, Measurement, and Program Modifications SSS WDR Requirement:
The Enrollee shall:
a) Maintain relevant information that can be used to establish and prioritize appropriate SSMP activities;
b) Monitor the implementation and, where appropriate, measure the effectiveness of each element of the SSMP;
c) Assess the success of the preventative maintenance program; d) Update program elements, as appropriate, based on monitoring or performance evaluations; and
e) Identify and illustrate SSO trends, including: frequency, location, and volume.
9. A Data Management
The City maintains relevant sewer-related information in its Computerized Maintenance Management System (CMMS), Geographic Information System (GIS), digital spreadsheets, and word processing documents, as well as the California Integrated Water Quality System (CIWQS) sanitary sewer overflow (SSO) database. The City also uses pipeline inspection software to manage closed circuit television (CCTV) inspection videos.
Examples of the types of data and information maintained by the City include the following:
• Asset location, material, and installation date
• Sewer line priority area locations
• Records of collection system maintenance
• Service call information
• Work order information to assign and track cleaning and repair activities • Spills main history
• CCTV inspection results, such as PACP ratings
70 9. B Monitoring and Assessment
The City is currently using the sewer GIS to more efficiently track and utilize records related to any segment of pipe in the system. The City is able to track maintenance and inspection activities. The City tracks the following parameters with which to measure effectiveness of the SSMP and its effectiveness in reducing spills.
• Number of Spills per year
• Volume of Spills per year
• Number of Spills per year by cause
• Number of dry weather Spills per year
• Length of gravity sewers cleaned annually
• Length of gravity sewers CCTV inspected annually
• Record of pump station maintenance work orders completed annually • Footage of sewer mainlines rehabilitation
• Capital projects completed

Any operational changes that are made to improve specific performance indicators will be documented in the SSMP Audit and reflected in the revised language of the SSMP. Element 10 discusses the SSMP Audit process in detail.
9. E Spill Trends
Performance indicator data, described in Section 9.c, are useful to assess the success of SSMP programs in meeting the goals listed in Element 1. SSO trends are displayed graphically in District’s annual Performance Measurement Reports. The City continues to evaluate overflow records to determine if repeat overflows have occurred. When location-specific capacity issues occur, the City installs bypass piping, and this method has proven successful in preventing additional overflows during heavy rain events. The City will continue to evaluate SSO trends to prevent and potentially reduce overflows.

78 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
4 1. 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. 79 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
5 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 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(l)(1)). 82 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
8 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 83 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
9 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. 84 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
10 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 December 6, 2022
11 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)

• 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:
87 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
13 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.
88 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
14 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. A sewage discharge from sanitary sewers to waters of the State is prohibited by this Order. Therefore, this Order does not allow degradation of waters of the State. In addition, this Order: (1) further expands the existing prohibition of sewage discharges to include waters of the State, in addition to waters of the United States as provided in previous Order 2006-0003-DWQ, and (2) enhances the ability for Water Board enforcement of violations of the established prohibitions.
3.3.2. State Water Board Sources of Drinking Water Policy On May 19,1988, the State Water Board adopted Resolution 88-63 (amended on February 1, 2006), titled Sources of Drinking Water, establishing state policy that all waters of the State, with certain exceptions, are suitable or potentially suitable for municipal or domestic supply.
3.3.3. State Water Board Cost of Compliance Resolution
On September 24, 2013, the State Water Board adopted Resolution 2013-0029, titled Directing Actions in Response to Efforts by Stakeholders on Reducing Costs of 89 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER

15 Compliance While Maintaining Water Quality Protection. Through this resolution, the State Water Board committed to continued stakeholder engagement in identifying and implementing measures to reduce costs of compliance with regulatory orders while maintaining water quality protection and improving regulatory program outcomes.
3.3.4. State Water Board Human Right to Water Resolution On February 16, 2016, the State Water Board adopted Resolution 2016-0010, titled Adopting the Human Right to Water as a Core Value and Directing its Implementation in Water Board Programs and Activities, addressing the human right to water as a core value and directing Water Board programs to implement requirements to support safe drinking water for all Californians.
On November 16, 2021, the State Water Board adopted Resolution 2021-0050 titled Condemning Racism, Xenophobia, Bigotry, and Racial Injustice, and Strengthening Commitment to Racial Equity, Diversity, Inclusion, Access, and Anti-racism. Among other actions, through Resolution 2021-0050, the State Water Board, in summary as corresponding to this General Order, reaffirms its commitment to its Human Right to Water resolution, upholding that every human being in California deserves safe, clean, affordable, and accessible water for human consumption, cooking, and sanitation purposes. Resolution 2021-0050 provides the State Water Board commitment to:
• Protect public health and beneficial uses of waterbodies in all communities, including communities disproportionately burdened by wastes discharge of waste to land and surface water;
• Restore impaired surface waterbodies and degraded aquifers; and • Promote multi-benefit water quality projects.
Through Resolution 2021-0050, the State Water Board also commits to expanding implementation of its Climate Change Resolution to address the disproportionate effects of extreme hydrologic conditions and sea-level rise on Black, Indigenous, and people of color communities, prioritizing:
• The right to safe, clean, affordable, and accessible drinking water and sanitation; • Sustainable management and protection of local groundwater resources; • Healthy watersheds; and
• Access to surface waterbodies that support subsistence fishing.
On June 7, 2022, the State Water Board adopted a Resolution, titled Authorizing the Executive Director or Designee to Enter into One or More Multi-Year Contracts Up to a Combined Sum of $4,000,000 for a Statewide Wastewater Needs Assessment, supporting the equitable access to sanitation for all Californians and implementation of Resolutions 2016-0010 and 2021-0050.
This General Order supports the State Water Board priority in collecting a comprehensive set of data for California’s wastewater systems, including sanitary sewer systems. Data reported per the requirements of this Order will be used with data from other Water Boards’ programs, to further develop criteria and create a statewide risk 90 STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
16 framework to prioritize critical funding and infrastructure investments for California’s most vulnerable populations, including disadvantaged or severely disadvantaged communities with inadequate or failing sanitation systems and threatened access to healthy drinking water supplies.
3.3.5. State Water Board Open Data Resolution
On July 10, 2018, the State Water Board adopted Resolution 2018-0032, titled Adopting Principles of Open Data as a Core Value and Directing Programs and Activities to Implement Strategic Actions to Improve Data Accessibility and Associated Innovation, directing regulatory programs to assure all monitoring and reporting requirements support the State Water Boards’ Open Data Initiative.
3.3.6. State Water Board Response to Climate Change
On March 7, 2017, the State Water Board adopted Resolution 2017-0012, titled Comprehensive Response to Climate Change, requiring a proactive response to climate change in all California Water Board actions, with the intent to embed climate change consideration into all programs and activities.
3.4. California Environmental Quality Act
The adoption of this Order is an action to reissue general waste discharge requirements that is exempt from the California Environmental Quality Act (Public Resources Code section 21000 et seq.) because it is an action taken by a regulatory agency to assure the protection of the environment and the regulatory process involves procedures for protection of the environment (Cal. Code Regs., Title 14, section 15308). In addition, the action to adopt this Order is exempt from CEQA pursuant to Cal. Code Regs., Title 14, section 15301, to the extent that it applies to existing sanitary sewer collection systems that constitute “existing facilities” as that term is used in sections 15301 and 15302, to the extent that it results in the repair or replacement of existing systems involving negligible or no expansion of capacity.
3.5. State Water Board Funding Assistance for Compliance with Water Board Water Quality Orders
The State Water Board, Division of Financial Assistance administers the implementation of the State Water Board financial assistance programs, per Board-adopted funding policies. Among other funding areas, the Division administers loan and grant funding for the planning and construction of wastewater and water recycling facilities per funding program-specific policies and guidelines. Applicants may apply for Clean Water State Revolving Fund low-interest loan, Small Community Wastewater grant funding assistance, and other funding available at the time of application, for some of the costs associated with complying with this General Order.
Funding applicants may obtain further information regarding current funding opportunities, and Division of Financial Assistance staff contact information at the following website: Financial Assistance Funding - Grants and Loans | California State Water Resources Control Board.

17 Section 13477.6 of the Water Code authorizes the Small Community Grant Fund.
The Small Community Grant Fund allows the State Water Board to provide grant funding assistance to small, disadvantaged communities and small severely disadvantaged communities that may not otherwise be able to afford a loan or similar financing for projects to comply with requirements of this General Order. The State Water Board also considers loan forgiveness on a disadvantaged community-specific basis.
For disadvantaged communities’ wastewater needs, the State Water Board places priority on the funding of projects that address:
• Public health;
• Violations of waste discharge requirements and National Pollutant Discharge Elimination System (NPDES) permits;
• Providing sewer system service to existing septic tank owners; and • High priority public health and water quality concerns identified by a Regional Water Board.
3.6. Notification to Interested Parties
On January 31, 2022, the State Water Board notified interested parties and persons of its intent to reissue Sanitary Sewer Systems General Order 2006-0003-DWQ by issuing a draft General Order for a 60-day public comment period. State Water Board staff conducted extensive stakeholder outreach and encouraged public participation in the adoption process for this General Order. On March 15, 2022, the State Water Board held a public meeting to hear and consider oral public comments. The State Water Board considered all public comments prior to adopting this General Order.
THEREFORE, IT IS HEREBY ORDERED, that pursuant to Water Code sections 13263, 13267, and 13383 this General Order supersedes Order 2006-0003-DWQ, Order WQ 2013-0058-EXEC, and any amendments made to these Orders thereafter, except for enforcement purposes and to meet the provisions contained in Division 7 of the Water Code (commencing with section 13000) and regulations adopted thereunder, and the provisions of the Clean Water Act and regulations and guidelines adopted thereunder, the Enrollee shall comply with the requirements in this Order.
