TO:Andrew P. Powers, City Manager
FROM:Clifford G. Finley, Public Works Director
DATE:May 24, 2022
SUBJECT: City of Thousand Oaks Sewer System Management Plan Update (MI 2632)
RECOMMENDATION:
Approve the recently updated 2022 Sewer System Management Plan and its findings and recommendations (MI 2632).
FINANCIAL IMPACT:
No Additional Funding Requested. $130,000 is included in the Adopted FY 2021-23 Wastewater Fund Capital Budget. The total project cost was estimated at $120,000. The State requires an update of the Sewer System Management Plan (SSMP) document every five years, as well as a biennial internal audit. As part of the budgeting process, funding for future audits and updates will be included in subsequent capital budget cycles.
BACKGROUND:
The California State Water Resources Control Board (SWRCB) issued a waste discharge requirement (WDR) permit on May 2, 2006, to regulate sanitary sewer systems. This permit is known as SWRCB Order No. 2006-0003, Statewide General Waste Discharge Requirements for Sanitary Sewer Systems. This permit, among other regulations, requires local public sewer collection system agencies to develop a SSMP (Attachment #1). SSMPs must be self-audited at least every two years and updated every five years from the original adoption date by City Council. The original SSMP was approved by City Council at a public meeting and adopted on September 9, 2008, followed by the first update to the SSMP adopted by City Council on March 22, 2016. The second update to the SSMP was completed in March 2022. As part of the updating requirement, the SSMP must be reviewed, updated, and approved by City Council, then posted to the SWRCB website.

1 DISCUSSION/ANALYSIS:
To prepare the SSMP update, staff solicited proposals from professional engineering firms with experience in the preparation of SSMPs, as well as the current regulations and requirements from the SWRCB.
In accordance with Government Code section 4526 and Thousand Oaks Municipal Code (TOMC) section 3-10.401, staff solicited an informal Request for Proposals (RFP) to existing on-call wastewater consultant firms for the SSMP Update and Audit. City Council authorized a task order with HDR, Inc., on March 16, 2021, and the SSMP document was finalized in March 2022.
The SSMP documents plan for properly managing, operating, and maintaining the City of Thousand Oaks’ (City) sanitary sewer collection system, preventing sanitary sewer overflows (SSOs) from occurring, preventing SSOs that do occur from reaching waterways, and minimizing and mitigating any adverse impacts from SSOs. The SSMP audit goal is the review of the following tasks:
Operate the collection system in a safe manner to avoid personal injury and property damage.
Provide a plan and schedule to properly manage, operate, and maintain all parts of the City’s sanitary sewer collection system. Reduce and prevent both dry weather and wet weather sewer overflows. Minimize and mitigate the adverse impacts of SSOs that may occur, especially to waterways.
Prevent public health hazards associated with sewer system management. Protect the collection system by performing preventive maintenance and extending its useful life.
Provide adequate capacity to convey peak wastewater flows associated with the design storm events.
Ensure compliance with all regulatory requirements.
A thorough review of the previous SSMP document and the interim audits, as well as several workshop meetings with different City Public Works departments were performed to document existing systems for the SSMP update. The SSMP update document provides an in-depth overview of the existing City systems that are in place for the required maintenance and operation of the sanitary sewer network. The SSMP is a living document that will require scheduled reviews/audits/updates to remain in compliance with the SWRCB regulations.
This project meets City Council Priority #9 to “Adopt and implement two-year Operating and Capital Improvement budgets that are aligned with best practices on fiscal sustainability and financial resiliency. Make strategic investments in existing critical public works infrastructure including pavement Item No.7K

1 Introduction and Goal
1.1 Purpose
This Sewer System Management Plan (SSMP) documents plans for properly managing, operating, and maintaining all parts of the City of Thousand Oaks (City)’s sanitary sewer collection system, preventing sanitary sewer overflows (SSOs) from occurring, preventing SSOs that do occur from reaching waterways, and minimizing and mitigating any adverse impacts from SSOs.
1.2 SSMP Goals
The goal of this SSMP and SSMP program implementation is to:
• Operate the collection system in safe manner to avoid personal injury and property damage
• Provide a plan and schedule to properly manage, operate, and maintain all parts of the City’s sanitary sewer collection system.
• Reduce and prevent both dry weather and wet weather SSOs • Minimize and mitigate the adverse impacts of SSOs that may occur, especially to waterways
• Prevent public health hazards associated with sewer system management • Protect the collection system by performing preventive maintenance and extending its useful life
• Provide adequate capacity to convey peak wet weather wastewater flows • Comply with all regulatory requirements related to the sewer system Achieving these goals will help to reduce and prevent SSOs, as well as mitigate any SSOs that occur. These goals are in alignment with the City’s strategic goals and objectives.
1.3 Regulatory Background
On May 2, 2006, the State Water Resources Control Board (SWRCB) adopted Order 2006-0003-DWQ1, the Statewide General Waste Discharge Requirements for Sanitary Sewer Systems (WDR), included as Attachment A1. The WDR prohibits any sanitary sewer overflow that results in a discharge to waters of the United States or that creates a nuisance as defined by California Water Code Section 13050(m). The WDR contains provisions requiring the City to:
1 State Water Resources Control Board has proposed a new Statewide Waste Discharge Requirements General Order for Sanitary Sewer Systems. If adopted, the reissued General Order will require future changes to the City’s SSMP and SSMP implementation.
The City will monitor the adoption of the new General Order and, if adopted, will address the new requirements according to the timelines for compliance stipulated in the Order.
Item No.7K
City of Thousand Oaks Sewer System Management Plan
2022 Sewer System Management Plan Update
1-2 | March 2022
• Report all SSOs.
• Take all feasible steps to eliminate SSOs.
• Take all feasible steps to prevent wastewater from discharging from storm drains into flood control channels or waters of the United States by blocking the storm drainage system and removing the wastewater from the storm drains. • Take all feasible steps and necessary remedial actions to control or limit the volume of the SSO, terminate the discharge, and recover as much of the wastewater discharged as possible for proper disposal, including any wash down water.
• Properly manage, operate, and maintain all parts of the sewer system and ensure system operators are adequately trained and possess adequate knowledge, skills and abilities.
• Allocate resources for the operation, maintenance and repair of the sewer system by establishing a proper rate structure, accounting mechanisms, and auditing procedures to ensure an adequate measure of revenue and expenditures.
• Provide adequate capacity to convey base flows and peak flows, including flows related to wet weather events. Capacity shall meet or exceed the design criteria as defined in the System Evaluation and Capacity Assurance Plan for all parts of the sanitary sewer system.
• Develop and implement a Sewer System Management Plan and make it available to the State and/or Regional Water Board as well as publicly available.
The SSMP must be approved by the governing board at a public meeting. • Conduct periodic audits at least once every two years to evaluate the effectiveness of the SSMP and compliance with SSMP requirements including identification of deficiencies and steps to correct them. • Update the SSMP every 5 years and have the governing board recertify the SSMP when significant updates are made
2. On August 6, 2013, the SWRCB amended Order 2006-003-DWQ by adopting Order WQ 2013-0058-EXEC, which modifies the monitoring and reporting requirements from the original order. Order WQ 2013-0058-EXEC is included as Attachment A2.
1.4 Application for Coverage
The City applied for coverage under the WDR on October 30, 2006 and was assigned a Wastewater Discharger Identification (WDID) for the City’s sanitary sewer system in the State Water Board’s SSO Database.
2 The timeline for SSMP updates may change if the proposed Statewide Waste Discharge Requirements General Order for Sanitary Sewer Systems is adopted. The City will monitor the adoption of the new General Order and, if adopted, will perform the next SSMP update according to the timeline for compliance stipulated in the new General Order.

1.5 System Overview
The City’s sewer service area encompasses approximately 55 square miles and has approximately 35,000 connections collecting wastewater from approximately 130,000 people. The sewer service area boundary largely coincides with the boundaries of the City and is not tributary to neighboring systems; however, a small southeastern portion of the City is serviced by Triunfo Water and Sanitation District.
The City’s sanitary sewer system, illustrated on Figure 1-1, consists of approximately:
• 415 miles of gravity sewer pipelines
• 35,000 connections
• 8,300 maintenance holes
• 2.5 miles of force mains
• 2 lift stations
The City does not own, operate nor maintain any portion of the service laterals connecting to the City’s sewer system mainlines. All wastewater collected by the City’s sanitary sewer system is conveyed to the Hill Canyon Treatment Plant for treatment to advanced tertiary levels suitable for unrestricted reuse. The treated effluent is recycled for agricultural irrigation and local landscaping projects (by other agencies). Any treated effluent not reused is disposed through a permitted surface water outfall to the North Fork of Arroyo Conejo Creek.
1.5.1 Gravity Sewer System
The City’s gravity sewer system consists of approximately 415 miles of pipelines ranging in diameter from 6 inches to 48 inches. Most of the sewer pipelines are comprised of vitrified clay or polyvinyl chloride (PVC) plastic. Other materials include asbestos cement, ductile iron, and cast iron.
1.5.2 Force Mains
The City has approximately 2.5 miles of force main pipelines ranging in diameter from 3 inches to 42 inches. Most of the force main pipelines are comprised of PVC plastic material. Other materials include reinforced concrete, asbestos cement, and ductile iron.
1.5.3 Lift Stations
The City owns and operates 2 active sewer lift stations, which are Lawrence Drive and Olsen Road Lift Stations.

This chapter describes the City’s SSMP Program organization and identifies the City’s authorized representative and key staff responsible for the implementation and development of the SSMP. This chapter also identifies the chain of communication for responding to and reporting an SSO.
2.1 Regulatory Requirements
The SWRCB Order No. 2006-0003-DWQ, Section D.13.ii – Organization requires the SSMP to have an organization section with the following information:
a. The name of the responsible or authorized representative as described in Section J of the order.
b. The names and telephone numbers for management, administrative, and maintenance positions responsible for implementing specific measures in the SSMP Program. The SSMP must identify lines of authority through an organization chart or similar document with a narrative explanation. c. The chain of communication for reporting SSOs, from receipt of a complaint or other information, including the person responsible for reporting SSOs to the SWQCB and RWQCB and other agencies if applicable (such as County Health Officer, County Environmental Health Agency, RWQCB, and/or California State Emergency Management Agency [now California Office of Emergency Services]).
2.2 Authorized Representatives
The City has identified an authorized representative in the California Integrated Water Quality System Project (CIWQS).

2.3 Sewer System Management Plan Program
Organization
The Public Works Department is responsible for providing water and wastewater service in the City. Within the Public Works Department, several groups are involved with implementation of the SSMP Program, including Engineering Division, Capital Improvement Projects, Operations, and Laboratory. Attachment B1 provides the complete SSMP Program organization chart, illustrating the lines of authority for staff responsible for implementing specific elements or measures of the SSMP Program.
Attachment B2 lists the contact information of City staff responsible for implementing SSMP elements or measures.
2.4 Sanitary Sewer Overflow Chain of Communications
Figure 2-1 illustrates the primary chain of communication from receipt of a complaint to notification and reporting of the SSO event by the City’s authorized representative during normal working hours, Monday through Thursday from 6:30 AM to 5 PM. Figure 2-2 illustrates the chain of communication during after-hours, which are considered all times outside of normal working hours. Refer to Chapter 6, Overflow Emergency Response Plan (OERP), for detailed SSO response and reporting procedures.
Other forms of communication that can indicate a potential SSO include Supervisory Control and Data Acquisition (SCADA) alarms from lift stations or alarms from one of the ten stationary flow meters throughout the sanitary sewer collection system. SCADA alarms directly alert field staff during working hours or personnel assigned to standby during after-hours, while flow meter alarms alert the City’s flow metering contractor, currently Hach, who will then notify the City.

4 Operation and Maintenance Program
This chapter describes the City’s collection system O&M Program, including sewer system mapping, preventative O&M, rehabilitation and replacement, staff training, and inventory of vehicles, equipment, and replacement parts.
4.1 Regulatory Requirements
The SWRCB Order No. 2006-0003-DWQ, Section D.13.iv – Operation and Maintenance Program requires the SSMP include the following elements:
a. Maintain an up-to-date map of the sanitary sewer system, showing all gravity line segments and maintenance holes, pumping facilities, pressure pipes and valves, and applicable stormwater conveyance facilities;
b. Describe routine preventive O&M 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 Preventive Maintenance 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 television inspections of maintenance holes 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.
4.2 Mapping
The City maintains sewer system mapping in the form of a geographical information system (GIS) database and a Sewer Atlas Map Book.
4.2.1 GIS Database
The City implemented a GIS database that includes quarterly updates, based on as- builts, from the County Assessor’s office of parcel and right-of-way GIS data. The street centerline data originated with TIGER street data and has been refined over the last Item No.7K
City of Thousand Oaks Sewer System Management Plan
2022 Sewer System Management Plan Update
4-2 | March 2022
decade with street name and shape data consistent with recorded documents. The GIS uses the NAD 83 State Plane California V projection.
The comprehensive GIS database contains detailed and up-to-date information on the sanitary sewer collection system network. Sewer facilities include gravity sewer lines, force mains, laterals, and lift stations, with information such as installation date, pipeline diameter, material, length, and interior lining.
All sewer maintenance holes, cleanouts and mainlines were digitized into the GIS database from as-built drawings. Each of the sewer assets on GIS include a hyperlink that connects directly to each corresponding as-built drawing. The vast majority of sewer drawings are at a horizontal scale of 1” = 40’ and georeferenced to property line intersections on the parcel GIS. In addition, these as-built drawings have been scanned and indexed in the City’s Laserfiche system, a content management platform. All as-built numbers are listed as an attribute of all sewer features in the GIS and can be used to access the as-built drawings using the City’s Laserfiche system. Figure 4-1 illustrates the City’s sanitary sewer collection system using GIS.

Item No.7K
City of Thousand Oaks Sewer System Management Plan
2022 Sewer System Management Plan Update
4-4 | March 2022
City office personnel, engineers, permit processing staff, and planners utilize the GIS database for a variety of purposes, including planning, engineering, permitting, inspecting, and O&M, as summarized below:
Planning: The GIS databases have information on existing sewer mains and piping network, which is used to evaluate the capacity of existing sewer mains and determine the size of proposed improvements.
Engineering: GIS contains attribute data of key sewer main elements (i.e., gravity sewer mains, laterals, maintenance holes, pump stations, force mains) that are essential to sewer improvement design.
Permitting: GIS contains attribute data of key sewer main elements that are essential to permitting for replacement of sewer lines.
Inspection: GIS sewer line attributes can be accessed outside the firewall by Public Works Construction inspectors in the field.
O&M: City field crews have electronic devices with GIS mapping in cleaning trucks to locate and identify sewer system assets. The Wastewater Utilities field crews utilize Windows 10 Toughpads that are synchronized with the latest GIS data once a week, while the Wastewater Utilities CCTV crew utilize Windows 10 desktop computers and are taken out, rather than synchronized live, once every two years to update with the latest GIS data.
All City office personnel have access to the GIS database through the web browser and, in the event of an emergency, City office personnel can access GIS data through mobile phone. The public currently does not have access to the GIS sewer system database.
The City is developing an online map for public homeowners to access as-built drawings.
4.2.2 Reasons and Data Sources for Sewer System Mapping Changes Mapping changes are not frequent; however, when staff identify errors, inconsistencies, or discrepancies with existing data, changes are conducted in a timely manner. As-built drawings are also simultaneously updated. Furthermore, capital improvements to the sewer system trigger the need for mapping updates. The Engineering Division and Capital Improvement Project (CIP) Division provides the Engineering Division GIS team with a list of capital improvement projects to update system mapping. Rehabilitation of sewer system assets are tracked as an attribute of a pipe segment and will not result in any changes to the unique identifier for a pipe segment or to how a pipe is spatially represented in the GIS database.
4.2.3 Sewer Atlas Map Book
The Sewer Atlas Map Book is developed from the GIS databases and includes a map sheet (1.5"=200' scale, 11"x17" paper) for each index area showing the location of force mains, abandoned lines, maintenance holes, cleanouts, valves, network structures (i.e. diversion, inlet, junction, sampling station, treatment plant, and wet well), and lift stations in relation to the City streets and property lines. The Atlas Map Book is secondary source of mapping information, with the GIS mapping being the primary data source for field crews. As a secondary source of mapping data, the Atlas Map Book is infrequently reprinted with the most recent published version printed in 2009. Wastewater Utilities Item No.7K
City of Thousand Oaks Sewer System Management Plan
2022 Sewer System Management Plan Update
March 2022 | 4-5
Maintenance values the Atlas Map Book as a backup source for locating sewer infrastructure when electronic databases are not available. The 2009 Atlas Map Book has outdated maintenance hole numbers; therefore, care should be taken to document work activities against updated maintenance hole numbers when documenting work activities. There are printed copies available within the City Hall and Emergency Operations Center, and if needed, the City has the capability to print individual pages from the Atlas Map Book.
4.3 Operation and Maintenance Standard Operating
Procedures
Wastewater Utilities Maintenance has developed a set of standard operating procedures (SOP) to support consistency in delivery of maintenance activities by the different Wastewater Utilities field crews as well as to support training of new crew members.
Table 4-1, on the following page, summarizes the SOPs utilizes by the Wastewater Utilities Maintenance.
Attachment D1 provides SOP (4001), SOP (4002), and SOP (4003) as examples of these SOPs. The SOPs are documented in the MaintStar maintenance management system and are available to crews at all times as a reference.
4.4 Preventive Maintenance
The City conducts an array of preventive maintenance activities to prevent service interruptions and system failures that could result in sewer overflows and to manage sewer system performance. Preventive maintenance activities include:
• Gravity sewer main cleaning
• Chemical root control
• Siphon maintenance
• Maintenance hole inspection and cleaning
• Canyon sewer visual inspections
• Flow meter maintenance
• Easement access maintenance
• Lift station maintenance
• Supervisory Control and Data Acquisition monitoring

4.4.1 Gravity Sewer Main Cleaning
Wastewater Utilities Maintenance field crews perform hydroflushing to clean the gravity sewer mains using the following cleaning strategies:
• Routine cleaning: Routine cleaning is performed on accessible gravity sewer mains from 6 to 12 inches in diameter at a frequency of 18 to 24 months. To Item No.7K
City of Thousand Oaks Sewer System Management Plan
2022 Sewer System Management Plan Update
March 2022 | 4-7
improve response times to customer pipes, the City cleans the sewer system from outward to inward where pipes are older.
• Hot spot “Trouble Areas” cleaning: Hot spot “trouble areas” cleaning is a form of accelerated preventive maintenance and is used on pipe segments with a history of maintenance issues. These pipelines are assigned more frequent cleaning with a 1-, 3-, or 6-month cleaning cycle.
• Reactive cleaning: Reactive cleaning is performed when Wastewater Utilities Maintenance becomes aware of a sewer overflow or potential blockage affecting sewer system performance resulting. A sewer cleaning crew will respond to customer complaints to investigate the issue and will clean pipe segments suspected of having a blockage to restore service.
Sewer Cleaning Frequency Adjustments
Wastewater Utilities Maintenance is continually evaluating the performance of the sewer system and the causes of maintenance issues. Hydroflushing crews document the type and severity of material encountered when cleaning a pipe segment in their field notes.
This information is then used to determine whether a change to maintenance cycle is needed.
4.4.2 Chemical Root Control
Pipe segments with pervasive root intrusion issues are chemically treated with a root growth inhibitor. The City uses a contractor to perform root foaming on approximately 19,700 feet of pipelines and some maintenance holes. The Wastewater Utilities Maintenance Supervisor maintains a “root” file containing information on pipe segments with known root issues. If a pipe has light roots at a joint, it will be placed in the folder for potential root foaming.
4.4.3 Inverted Siphon Maintenance
The City has two inverted siphons that are inaccessible to cleaning equipment. The last mile of Unit W trunk line is an inverted siphon. The last 2000 feet of Unit Y trunk line is an inverted siphon. These inverted siphons are operating under pressure and at flow rates well above scouring velocity. Wastewater Utilities Maintenance treats the siphons with grease removal enzymes approximately every 3 months to prevent grease build-up.
4.4.4 Maintenance Hole Inspection and Cleaning
In addition to sewer cleaning, the City initiated a system-wide maintenance hole inspection program in 2015 and conducted visual inspections of the City’s 8,000 maintenance holes over the past 7 years. Field crews performing visual inspection measured maintenance hole size and material leading to updates to GIS attribute data.
Field crews also documented condition or maintenance issues requiring action resulting in maintenance hole repair and maintenance hole cleaning.

4.4.5 Canyon Sewer Visual Inspections
Canyon inspections are performed periodically on either a monthly or bi-monthly cycle depending on the canyon. Canyon inspection are also performed after significant rain events. Monthly inspection or bi-monthly inspection activities vary by pipeline and include above grade pipelines and supports, maintenance holes, laterals, and vents. Monthly canyon inspection locations include the following:
• Unit W W-U67 structure to Hill Canyon Treatment Plan (HCTP) • Lynn Ranch to Unit W (W-U-31 structure)
• Calle Brusca
• Box Canyon
Inspection activities occurring every 2 months vary by infrastructure and include maintenance holes, junction box, access roads, creek crossings, pipe encasement, brush, security doors, structures, valves, and pipe condition. Locations inspected every 2 months include the following:
• Unit X Maintenance holes from California Lutheran University (CLU) to A-37.1 • Unit A A-20 to A37.1
• Unit Y Y-1 to HCTP
• Unit W
• Lower Tunnel Door
• W-2 Structure
• W-J Structure
• Rancho Conejo Lateral
• Calle Salto Lateral
• W-D and W-1 Structures
• Shapell Lateral
• W/F Structure and W-A Structure
Attachment D3 includes the data collection forms used to document the results of canyon visual inspections.
4.4.6 Flow Meter Maintenance
The City leases 10 permanent flow meters from a flow meter contractor. The flow meter contractor maintains the flow meters and coordinates maintenance access with O&M staff. City provides traffic control and access to flow meter locations. The flow meter contractor uses cloud-based tools to collect, manage and store flow meter data and to make the data available to City staff for review and analysis.

4.4.7 Easement Access Maintenance
Natural vegetation growth in easements can restrict access to sewer infrastructure.
Wastewater Utilities Maintenance field crews maintain easements to keep sewer infrastructure accessible for maintenance activities, as well as for visual inspection. Work orders are created in the MaintStar MMS and are tracked according to the sewer infrastructure associated with the easement.
4.4.8 Lift Station Maintenance
Wastewater Utilities Maintenance performs lift station preventive maintenance and weekly inspection for two active lift stations. The two lift stations, Olsen Road and Lawrence Drive, are inspected once per week on Mondays. Staff records power, pressure, and flowrate. Maintenance crews also perform scheduled quarterly maintenance activities at each of the lift stations. The lift station maintenance activities are described below.
Lift Station Site Check List
In addition, staff uses a site check list to log conditions of the lift station, which includes the following:
• Outside of Building
o Graffiti
o Doors are secured
o Valves are chained and locked
o Chain link fences are secured
o “No Trespassing” signs are posted
o Weeds or debris

Wet Well Grease Control
Approximately once a month, Wastewater Utilities Maintenance adds degreaser into the wet wells to reduce grease buildup.
Lift Station Quarterly Maintenance
Lift stations are maintenance on a quarterly schedule. In the first and third quarter, the Wastewater Utilities Maintenance crew will perform 6-month maintenance activities and will adjust the pump wear plates. Second and fourth quarter maintenance focuses on changing the pump oil.
Olsen Road Lift Station Generator Checks
A Wastewater Utilities Maintenance crew will run the generator at Olsen Road Lift Station at least every other week to confirm the generator is functioning adequately.
4.4.9 Supervisory Control and Data Acquisition Monitoring The City owns two different SCADA systems, one serving both the water distribution and sewer system and the other serving the Hill Canyon Treatment Plant. The main control center for SCADA is located at the Municipal Service Center and is reviewed daily. The Municipal Services Center is open 24 hours a day, 7 days a week. Screens displaying SCADA information are visible in a common area with the administrative personnel. If a SCADA alarm is triggered, administrative staff will be alerted. During after-hours, the alarms will transmit to a standby phone and are answered by standby personnel.
4.4.10 Odor Control
Odor complaints are not frequent; however, if received, the City will investigate, troubleshoot, and clean the line to address the source of the issue. The City will also take the additional measure of corking and sealing the maintenance hole cover. Odor complaint response is documented in MaintStar. If issues are reported via email or phone, administrative staff will document the issue into Maintstar and will contact Wastewater Utilities Maintenance to address the issue.
4.4.11 Underground Service Alerts Utility Locates
Wastewater Utilities Maintenance field crews respond to Underground Service Alerts on an as-needed basis to locate sewer system infrastructure within the work zone of pending construction activities. This reduces the likelihood contractors will damage City sewer pipelines during construction activities.
4.5 Work Management System
The City utilizes various computerized system to management maintenance activities, including the following:
• GIS: The City uses GIS to collect maintenance hole inspection data and document pipe lining history.
Item No.7K
City of Thousand Oaks Sewer System Management Plan
2022 Sewer System Management Plan Update
March 2022 | 4-11
• MaintStar Maintenance Management System (MMS): This program includes a work management module for documenting work activities, such as customer complaints, work orders, and emergency and preventive maintenance activities against specified wastewater assets. The module allows City staff to computerize its maintenance program and track the maintenance history on individual maintenance holes and pipe segments. The City plans to will integrate GIS into MaintStar through automated nightly synchronization and to include work order information on the map. This program may integrate condition assessment data in the future.
• InfraMap: Wastewater Utilities Maintenance field crews use this GIS-based, third-party software program to collect field data such as cleaning and field observations. Pipes that require cleaning are color-coded from red to green, with red pipes requiring cleaning and green pipes indicating the pipes have been recently cleaned. Field data collected using InfraMap is them migrated from InfraMap to MaintStar.
• GraniteNet: CCTV vans utilize this software to manage condition of assets.
CCTV vans generate work orders for lift stations canyons, and maintenance holes, which documents number of hours, hydrocleaning, maintenance hole inventory, pipe material replacement, or any other issues (i.e., root intrusion).
Repairs and CCTV are currently not documented by asset ID unless noted within the notes field of the work order. Inspection data from the vans are uploaded once a month to GraniteNet. Unlike MaintStar, this process is not currently automated.
• Infrastructure Reinvestment Intelligence System (IRIS): IRIS is an asset management dashboard that utilizes asset data and performs asset management calculations and analyses. The software is designed to supplement asset record systems (e.g., MMS, GIS) by performing asset management calculations that these systems cannot perform. IRIS projects the future asset Rehabilitation and Replacement (R&R) needs, highlights high-risk assets, calculates the appropriate budget required to mitigate the high-risk assets.
4.6 Condition Assessment and Rehabilitation and
Replacement Planning
The City has processes to identify and prioritize sewer system needs and to identify near-term and long-term actions to address system needs. Processes include inspection, condition assessment and rehabilitation planning processes. The City also performs long-term rehabilitation forecasting to estimate the long-term financial requirements associated with sewer system rehabilitation and renewal.

4.6.1 Gravity Main Closed-Circuit Television Inspection and Rehabilitation Planning
Gravity Main CCTV Inspection
The City has a goal to inspect the sewer system on a 15-year cycle. Wastewater Utilities Maintenance has one CCTV crew performing CCTV inspection and is inspecting approximately 15,000 feet per month and 34 miles annually. The City recently invested in new CCTV inspection equipment. The City documents inspection observations using the National Association of Sewer Service Companies (NASSCO) Pipeline Assessment and certification Program (PACP) standard.
The plan and schedule for CCTV inspection is prioritized based on pipe age, pipe material and maintenance history. The City has inspected approximately 65 percent of the sewer system since the beginning of the latest 15-year inspection cycle, including the middle of town and older portions of the system. In addition to on-going CCTV inspection and condition assessment, the City televises newly constructed pipelines and newly rehabilitated pipelines as the basis for acceptance, providing a baseline CCTV inspection for new and rehabilitated pipelines.
The most recent inspection conducted since 2019 are stored electronically in GraniteNet software. Inspections conducted between 2013 and 2019 are stored electronically on an external drive. Prior to that, the CCTV documentation is only accessible via hardcopy files. Some of the CCTV inspections the City is performing are repeat inspections to investigate complaints and support other departments. The City is inspecting pipelines up to 30 inches in diameter, with pipes ranging from 15-inch to 30-inch inspected every 24 months during low flows.
Gravity Main Rehabilitation Planning
The City is continually evaluating the rehabilitation needs of the gravity sewer system to identify capital improvements. Wastewater Utilities Maintenance collaborates with the Capital Improvements Program Division to conduct CIPP lining projects on a cycle of approximately two years. Over the past decade, the City has been diligent with investing in pipeline rehabilitation and there is currently very little backlog in either the “lining” file or the “root” file. Most capital improvements projects on the sewer system over the last decade have been lining projects to rehabilitate older gravity sewer pipelines.
Lining projects are identified based on recommendations from Wastewater Utilities Maintenance based on review of CCTV inspection observations. The Wastewater Utilities Maintenance Supervisor maintains a “lining” file documenting the pipe segments that are candidates for lining. The pipe segments in the lining folder are evaluated periodically to create a lining project. The decision criteria for selecting pipe segments for repair, rehabilitation or replacement includes:
• Severe structural defects such as collapse, missing wall, and broken pipe. This is not very common.
• Significant sags
• Offset joints
Item No.7K
City of Thousand Oaks Sewer System Management Plan
2022 Sewer System Management Plan Update
March 2022 | 4-13
• Fractures
• Pervasive root intrusion
The Wastewater Utilities Maintenance Supervisor also maintains a separate root intrusion file documenting pipe segments with known root intrusion issues. These pipe segments are evaluated at the same time and possibly included in a lining project.
If a pipe segment has a significant defect and it is localized, the City may decide to perform a localized point repair. Repair projects are categorized into three tiers:
• Small Projects – In House Repair
• Medium – On Call Contractors (if requires trenching) may do lining using this approach.
• Large Projects over $60,000 to $75,000 are bid out
4.6.2 Maintenance Hole Rehabilitation
Wastewater Utilities Maintenance field crews recently completed a multi-year inspection program of the City’s 8,000 maintenance holes. Field crews identified maintenance holes with repair and rehabilitation needs. These maintenance holes repair and rehabilitation needs are either addressed by in-house crews, added to lining projects, or are grouped into separate maintenance hole rehabilitation projects.
4.6.3 Force Main Inspection and Rehabilitation
The City’s two force mains were recently rehabilitated with cured-in-place pipe (CIPP) lining and are in good condition.
4.6.4 Lift Station Inspection and Improvements
In addition to weekly inspections and quarterly maintenance activities, Wastewater Utilities Maintenance will team with Capital Improvements Program Division staff to perform lift station condition assessment every two years to identify lift station capital investment needs. The Capital Improvements Program Division gets involved with larger projects related to the lift station. The CIP Division initiates CIP projects every 2 years with sewer, electrical, or instrumentation crew input to identify the needed improvements.
The lift station condition needs are identified by a multi-disciplinary team consisting of Wastewater Utilities Maintenance crew providing expertise in mechanical systems, while an electrical and instrumentation crew identify the needs of the electrical and instrumentation systems. Capital Improvements Program Division staff provide expertise with lift station structural components. Currently from a structural perspective, both lift stations are reported to be in good condition.
4.6.5 Financial Planning for Sewer System Needs
In addition to system-wide inspection and condition assessment, the City utilizes IRIS software to model the long-term investment needs of the sewer system. IRIS is an asset management software program that models the lifecycle costs associated with sewer system assets based on the age and expected useful life of pipeline and lift station Item No.7K
City of Thousand Oaks Sewer System Management Plan
2022 Sewer System Management Plan Update
4-14 | March 2022
assets. The model forecasts the long-term investment required to address rehabilitation and replacement needs. The final result is a Water and Wastewater Asset Management Plan with forecast outputs that inform financial rate setting and support the City with justifying investment in sewer system rehabilitation and replacement. The most recent Water and Wastewater Asset Management Plan can be found online at:
https://www.toaks.org/Home/ShowDocument?id=25688
The City also maintains an internal 10-year capital improvement plan and includes a line item for sewer system rehabilitation every 2 years.
4.7 Training
Safety Procedures
The City provides safety and training programs on a regular basis for staff in sewer collection system operations, maintenance, and monitoring. For instance, Job Safety Analysis reviews are completed once a month on various equipment, such as combination hydroflushing vacuum units (i.e., Vactor and VacCon) or shoring. Key safety aspects reviewed include required personal protective equipment, sequence of basic job steps, potential accidents or hazards, additional safety job procedure. The reviews also include descriptive operating procedures and precautions for proper usage. The Job Safety Analysis calendar is included as Attachment D4. Project specifications require contractor certifications or training to complete work.
Onboarding and Training Rotations
New Wastewater Utilities Maintenance staff are onboarded through training rotations every two weeks to become familiar with how to conduct canyon inspections and how to operate each key piece of equipment, such as combination hydroflushing vacuum units (i.e., Vactor truck and VacCon truck) and CCTV trucks. The trainings address the skills necessary to perform proper operations and maintenance, to provide timely and effective emergency response, and to incorporate recognized safety practices.
According to Figure 2-2, either a Water Utilities Maintenance or Wastewater Utilities Maintenance crew member will be assigned to the Duty response and respond to sanitary sewer overflow calls during after-hours. Therefore, new Wastewater Utilities Maintenance staff are cross trained in water distribution system operations and maintenance activities for about 2 to 3 months, while new Water Utilities Maintenance staff are cross trained in sewer system operations and maintenance activities.
Certification
Certification in Collection System Maintenance is preferred, but not required to work in Wastewater Utilities Maintenance. Even so, several crews members have attained Collection System Maintenance certification through the California Water Environment Association’s certification program (CWEA). Water Utilities Maintenance staff are required to have a Distribution Grade 1 certification from the State Water Resource Control Board’s Drinking Water Operator Certification Program (DWOCP). Several Water Utilities Maintenance staff also have CWEA Collection System Maintenance certification.

The City owns and maintains a variety of vehicles and equipment used for operations and maintenance of the sewer collection system and emergency response. The City utilizes the Fleet Maintenance shop at the Municipal Service Center for any issues and for regular equipment maintenance. Combination hydroflushing and vacuum units and CCTV vans are replaced approximately every 10 years. If cameras cannot be fixed in- house, cameras are sent to Plumber’s Depot for repair at CUES.
4.8.1 Major Vehicles and Equipment
The following list summarizes the City’s major vehicles and equipment at the Municipal Center:
• Combination hydroflusher/vacuum units (2)
• CCTV Van and Camera Equipment (1)
• Backhoe and Trailer (1)
• Pickup Trucks (4)
• Bypass pumps (2)
• Portable Generators (3)
• Pressure Washers (2)
4.8.2 Contingency Equipment and Spare Replacement Parts Wastewater Utilities Maintenance maintains an inventory of contingency equipment and spare replacement parts intended to minimize vehicle, equipment, and facility downtime.
Replacement parts for vehicles and appropriately maintained emergency response equipment and accessories, such as one check valve and two extra rotating assemblies, allow field crews to effectively respond to incidents and efficiently perform routine maintenance. In emergencies, a 6-inch portable bypass pump that connects to Olsen Road Lift Station and can be used to bypass sewer pipelines at the lift station. Any pipes over 8-inch will require support from Rain-for-Rent for temporary assistance in bypassing flows. In addition, the City has installed a permanent generator to provide backup power for Olsen Road Lift Station and owns three portable generators that Wastewater Utilities can utilize to perform bypass pumping activities.

a. Design and construction standards and specifications for the installation of new sanitary sewer systems, pump stations and other appurtenances; and for the rehabilitation and repair of existing sanitary sewer systems; and; b. Procedures and standards for inspecting and testing the installation of new sewers, pumps, and other appurtenances and for rehabilitation and repair projects.
5.2 Design and Construction Standards and Specifications The City engineers, developers, and consultants currently utilize a set of Wastewater Design and Construction Standards as the basis for design and construction of sanitary sewer collection systems. The Wastewater Design and Construction Standards, approved and adopted by City Council in 1979 (revised in 1980), are accessible on the City’s webpage at:
https://www.toaks.org/departments/public-works/engineering-traffic/wastewater-design- construction-standards
The Wastewater Design and Construction Standards provide the design criteria, construction requirements, and construction standards for new sewer system infrastructure as well as standards for inspecting and testing the installation of new sewer system infrastructure.
5.2.1 New Sanitary Sewer Infrastructure
The Wastewater Design and Construction Standards provide a comprehensive set of standards for the major component of new sewer system infrastructure including sewer pipelines, maintenance holes, cleanouts, laterals, lift stations, and force mains. Design and construction specifications for air release valves are prepared as part of the corresponding sewer system capital improvement project and are subject to review and approval by City staff.
5.2.2 Rehabilitated and Repaired Sewer System Infrastructure The City is largely built out and most of the capital improvement efforts are rehabilitation and repair, rather than installation of new pipelines. Standards for design and construction are prepared individually for specific sewer system capital improvement Item No.7K

projects. Sewer pipeline rehabilitation specifications are developed by consultants in collaboration with City engineering staff. Over time, City staff have assembled a library of sewer pipeline rehabilitation specifications from various projects. This is necessary due to the constant flux in pipeline rehabilitation technologies and tools available in the industry.
5.2.3 Design Review and Approval
Standards are enforced through a permitting process to ensure design and construction is adequately performed. City engineering staff perform plan checks to ensure the design drawings are calling out and referencing the standards. The City performs plan check at different stages of the design process. Typically, plan checks are performed at the 30%, 60%, and 90% design phase on projects.
5.3 Inspection and Testing of New and Rehabilitated
Sewer Infrastructure
New and rehabilitated sewer infrastructure require inspection and testing under specific procedures and standards. The City requires contractors to maintain a performance bond for 10 years to address latent construction defects on capital improvement projects.
5.3.1 Inspection and Testing Procedures and Standards
The City performs various types of inspection and testing during and after construction to ensure sewer system infrastructure is built properly before accepting new or rehabilitated infrastructure into the sewer system. The City’s construction inspector and capital improvement Project Engineer are responsible for sewer infrastructure acceptance and approval of capital improvements or new development. Table 5-1 lists the various inspection and testing procedures the City employs to ensure sewer system infrastructure is properly constructed.
5.3.2 Inspection and Testing Resources
City staff evaluate upcoming capital improvement projects to determine the project management and construction inspection workload requirements and assign project management and construction inspection duties to either in-house staff or to a third party, depending on the size of the project and the workload demands.
Regardless of who performs project management and construction inspection duties, the resources assigned to perform these duties are performed in conformance with plans, contract documents, and City standards.

7 Fats, Oils, and Grease Control Program
This chapter describes the City’s FOG control program. Oil and grease contributions to the City's wastewater collection system have been regulated by the City Municipal Code since the late 1970s, mandating installation and maintenance provisions for grease control devices (i.e., grease trap or grease interceptor) to alleviate grease discharged into the sanitary sewer collection system in over 400 food service establishments (FSE) and auto service repairs.
The Public Works and Community Development (Building Division) Departments have worked closely to ensure that appropriate fixtures, drains , and mop sinks associated with commercial kitchen and restaurant clean- up facilities are plumbed through these oil and grease separation devices. A new ordinance is in development to establish clarity on which establishments require a grease trap and guidance for determining the appropriate type, flow, operations, and size for grease removal device.
The Environmental Compliance group, within the Public Works Department , has worked closely with the Collection System Maintenance group. This effort is conducted to identify hotspot areas, isolate problematic sources, conduct stepped-up inspections, and require increase pumping and cleaning of traps and interceptors as needed. Where specific sources cannot be isolated, more routine cleaning and jetting of the collection system has been initiated.
7.1 Regulatory Requirements
The SWRCB Order No. 2006-0003-DWQ, Section D.13.vii – FOG Control Program requires the City to prepare and implement a FOG source control program to reduce the amount of FOG substances discharged to the sanitary sewer collection system. This plan will 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 control devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, best management practice (BMP) requirements, record keeping and reporting requirements;
e. Authority to inspect grease producing facilities, enforcement authorities, and whether the Public Agency has enough staff to inspect and enforce the FOG ordinance;
Item No.7K
City of Thousand Oaks Sewer System Management Plan
2022 Sewer System Management Plan Update
7-2 | March 2022
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 pipe segments found to be prone to grease blockages.
7.2 Fats, Oils, and Grease Public Outreach Program
The City focuses public outreach education towards residential customers through sustainability blogs on the public website and towards the commercial kitchen and restaurant business sectors through inspections. Inspectors verbally educate proper disposal of FOG concurrently with facility inspections, such as during the review of pretreatment devices at auto repair services, inspection of restaurants for stormwater compliance with the MS4 permit, or inspection of school cafeterias.
7.3 Plan and Schedule for Disposal of Fats, Oils, and
Grease
The City supports proper disposal of fats, oils and grease generated within the City limits either by providing residential customers with a means for proper disposal and by requiring and enforcing proper disposal by commercial establishments.
7.3.1 Residential FOG Disposal
Among the services the City provides to residents, a Household Hazardous Waste Day (one day per month) is conducted for disposal of accumulations of household grease and cooking oil. The City also has an agreement with the neighboring city of Camarillo for residents to use their facilities for disposal on two additional days per month. Residents may also allow small accumulations of grease to congeal in a container and dispose of grease waste through solid waste/curbside collection and disposal to a landfill.
7.3.2 Commercial and Industrial FOG Disposal
Regarding the commercial and industrial community, the Municipal Code identifies thresholds for maintenance required for the operators of interceptors and traps based on the accumulation of both settled solids and oil and grease. According to Section
10.1-6.04, Control of Regulated Wastes, these units are required to be pumped out if at least 25 percent accumulated with grease. The new Ordinance in development will state the need for certified contract pumper to pump the grease. Although there is no mandated cleaning frequency, the grease interceptors and traps are typically checked by the establishments on a regular basis, either quarterly or biannually.
Removed material is either hauled to the City’s Hill Canyon Treatment Plant or legally disposed of outside of the city limits. Small grease traps under the sink are typically cleaned weekly.
There are three inspectors under the Public Works Environmental Compliance Group that delegate the facility inspections. The stormwater permit mandates inspectors to alternate inspecting FSEs and auto service repairs annually (1 year inspect FSE, next Item No.7K
City of Thousand Oaks Sewer System Management Plan
2022 Sewer System Management Plan Update
March 2022 | 7-3
year inspect auto service repairs), in which the inspectors use this session to check the manifest for record of cleaning.
7.4 Fats, Oils, and Grease Program Legal Authorities
Fats, oils and grease source control program legal authorities can be found in the Municipal Code in Title 10, Article 6. Industrial Waste Regulation. The Municipal Code can be accessed online at:
https://www.toaks.org/departments/city-clerk/municipal-code
7.4.1 Authority to Inspect and Enforce Fats, Oils, and Grease Program Requirements
The authority to inspect and enforce is contained in Municipal Code Section 10-1.604 - Control of Regulated Wastes, and Municipal Code Section 10-1.605 - Industrial Wastewater Monitoring and Reporting, of the Municipal Code. The Code provides two avenues to pursue compliance. The first is through capacity inhibition and maintenance with regards to grease removal devices. The second avenue is through monitoring by performing an oil and grease concentration analysis.
The City enforces FOG requirements by issuing a warning if the grease removal device is improperly maintained. If conditions persist through subsequent inspections, a fine is issued to the owner and/or user of the property.
The City employs three full time Environmental Compliance Inspectors to inspect facilities and enforce the regulations as well as document and correct compliance issues of the existing oil and grease discharge community.
7.5 Fats, Oils, and Grease Program Requirements
7.5.1 Requirements to Install Grease Control Devices
The requirement to install, maintain, and keep records of grease control devices is specified in Section 10-1.604, Control of Regulated Wastes, of the Municipal Code. The Code relies on the discretion of the establishment Director to identify that the property produces enough grease to warrant a grease control device. On a case-by-case basis, the City Engineering Department assists in the determination by evaluating the property and the menu. The establishments are responsible to report to the City if menus change.
7.5.2 Design Standards for Grease Control Devices
City code requires a restaurant, or other establishment, that discharges wastewater containing grease to install and regularly maintain an interceptor to prevent excessive discharges of grease into the waste-water system. The type and size shall be as regulated by the building provisions of the Municipal Code or as required by the Public Works Director.
In practice, the Building Division will review building permits to determine whether a permit application for a new or existing establishment triggers the requirement for a grease trap or interceptor. All commercial kitchens requiring a hydromechanical grease Item No.7K
City of Thousand Oaks Sewer System Management Plan
2022 Sewer System Management Plan Update
7-4 | March 2022
interceptor or gravity grease interceptor are required to size the device according to the most recent adopted California Plumbing Code. Grease traps are installed inside the restaurant and can have capacity ranging from 50 to as high as 250 gallons, while grease interceptors are installed outdoors with a minimum capacity of 750 gallons to as high as 1,200 or 1,500 gallons. The maximum size for a grease interceptor is 3,000 gallons.
7.5.3 Maintenance Requirements for Grease Control Devices Each commercial kitchen with a grease control device is required to employ an appropriate service or procedures for periodic collection of accumulated grease from any grease control device. Inspectors from Public Works Environmental Compliance will review maintenance records and compliance with the 25% rule. The 25% rule requires grease control devices to have no more than 25% of the volume of the device consumed by accumulated grease. Commercial kitchens are not allowed to introduce grease into any sewer lateral, public sewer, storm drain, or public right-of-way. FSEs are required to supply documentation, such as invoices, to prove compliance with grease control device maintenance requirements.
7.5.4 Record Keeping and Reporting Requirements
Each commercial kitchen with a grease control device is required to keep 2 years of records of cleaning, maintenance, and grease removal. A separate maintenance log must be maintained for each grease control device and posted in the immediate vicinity of each device. Maintenance logs will include the following information: grease control device location and volume; maintenance dates; volume removed (gallons); disposal methods; and name of person performing maintenance; and, if the person is not employed by the commercial kitchen, the name, address, and phone number of the person or company performing the maintenance activities.
7.6 Fats, Oils, and Grease Control Program Resources
The City has assigned FOG program inspection and enforcement duties to three Environmental Compliance Inspectors in the Public Works Department who perform compliance inspections to enforce auto, stormwater, industrial and grease control requirements in the Municipal Code. This level of staffing enables the City to accomplish an inspection of each food service establishment kitchen once approximately every two years.
7.7 Sewer System Maintenance Program for Fats, Oils,
and Grease
Identification of pipe segments prone to blockage and the cause of the blockages is based on review of available information potentially including one or more of the following sources: blockage history, CCTV inspection data, FOG investigations, and FOG source control inspections of FSEs. Pipes prone to blockages can be addressed through more frequent cleaning and targeted outreach and/or inspection of upstream dischargers. Areas known to be a problem have been put into monthly, quarterly, or Item No.7K

2022 Sewer System Management Plan Update
March 2022 | 7-5
semiannual cleaning frequencies. This program is described in detail in Chapter 4, Operations and Maintenance Program.
Wastewater Utilities Maintenance has identified sections of the sewer system subject to grease blockages and established a cleaning maintenance schedule for each section.
When a grease-related SSO occurs, Wastewater Utilities Maintenance will monitor the site quarterly to determine whether grease accumulation in the pipe segment is a pervasive issue. If grease build-up continues to be an issue, Wastewater Utilities Maintenance will place the pipe segment on a 1, 3, or 6-month trouble spot cleaning cycle depending on the severity of the grease accumulation detected. If nearby food service establishments are suspected, Environmental Compliance Inspectors will perform an inspection of the nearby FSEs upstream of the blockage, including the review of maintenance records for grease control devices. If a private residence is suspected as the source of the grease discharge, Wastewater Utilities Maintenance will notify and educate the residence on practices they can employ to prevent the grease discharges.
7.8 Preventive and Source Control Measures
The City uses a combination of preventive and source control measures to address FOG discharges to the sewer system, including the following:
FSE inspections: This involves source control inspections of FSEs to determine compliance with FOG ordinance requirements.
Trouble Spot Program: This involves scheduled recurrent cleaning of known grease problem areas on frequencies of 1, 3, or 6 months.
Sewer Main and Maintenance Hole Inspection Program: This involves the visual and/or televised inspection of mains and maintenance holes.
Sewer main replacement: This involves the repair, replacement, or rehabilitation of impacted sewers to improve sewer flow velocities. An outside contractor is engaged if the line can be repaired from maintenance hole to maintenance hole.

8 System Evaluation and Capacity Assurance
Plan
This chapter describes the City’s System Evaluation and Capacity Assurance Plan. The System Evaluation and Capacity Assurance Plan utilizes information from the most current wastewater master plan, the City of Thousand Oaks Wastewater Interceptor Master Plan Final Report (Master Plan) from July 2002. The Master Plan can be found online at:
https://www.toaks.org/home/showpublisheddocument?id=14934
8.1 Regulatory Requirements
The SWRCB Order No. 2006-0003-DWQ, Section D.13.viii – System Evaluation and Capacity Assurance Plan requires that the City prepare and implement a CIP that will provide hydraulic capacity of key sanitary sewer collection system elements for peak dry weather flow conditions, as well as for peak flows under an 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 CIP 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 of the order.
8.2 System Evaluation
The City’s 2002 Wastewater Interceptor Master Plan was prepared to provide a comprehensive assessment of the structural condition and hydraulic capacity of the City’s interceptor sewer system and a phased 10-year plan for capital improvements.
The Wastewater Interceptor Master Plan analyzed the City’s wastewater service area, Item No.7K

which largely coincides with the boundaries of the City. The Wastewater Interceptor Master Plan is developed to reflect the ultimate buildout of the City collection system.
The projected near-term and long-term average dry weather flows and peak wet weather flow, as estimated from the 2002 Wastewater Interceptor Master Plan and 2020 Treatment Plant Master Plan, are presented in Table 8-1. The current average dry weather flow in the system (total of flows to Hill Canyon Treatment Plant) is approximately 9 million gallons per day (MGD).

1. Peak wet weather flows are estimated using average dry weather flows from the 2020 Treatment Plant Master Plan and wet weather peaking factor of 2.5 per the 2002 Wastewater Interceptor Master Plan.
The City currently monitors flows at 10 flow monitoring locations throughout the collection system, including influent flows to the Hill Canyon Treatment Plant. The City conducted a treatment plant analysis as part of the 2020 Hill Canyon Treatment Plan Master Plan, which provided an updated projection of City wastewater flows into the plant.
Recent project-specific sewer studies evaluated the sewer collection system capacity against projected flows in the 2002 Interceptor Master Plan as well as the existing flow meter data. While the 2002 Interceptor Master Plan did not identify capacity deficiencies within the system at the time, several projects were identified to address potential capacity deficiencies until buildout conditions. The City has since implemented nearly all the capacity projects recommended in the 2002 Interceptor Master Plan and continues to monitor the system for flows and SSOs using field inspections, flow monitoring data, and influent data for the Hill Canyon Treatment Plant.
8.3 Design Criteria
Design criteria for evaluating the capacity of the existing sewer system and new facilities were developed as part of the 2002 Wastewater Interceptor Master Plan, City Wastewater Design and Construction Standards, and subsequent project-specific sewer studies. For gravity sewers, the criteria are based on maximum flow depth under design peak wet weather flow, expressed as the ratio of flow depth to pipe diameter. These criteria are presented in Table 8-2.

The City’s Wastewater Design and Construction Standards also includes criteria for design of sewer facilities. These criteria are primarily intended for design and construction of new sewer facilities to serve new development and include average sewage generation rates based on land use type, peaking factors based on population (for residential developments), or a specified peaking factor equation, and criteria for minimum sewer velocities and slopes. The sewage generation rates are shown in Table 8-3 and are consistent with those used in the 2002 Wastewater Interceptor Master Plan and project sewer studies. Minimum slope criteria from the Wastewater Design and Construction Standards are also presented in Table 8-4.

8.4 Capacity Enhancement Measures
The 2002 Wastewater Interceptor Master Plan recommended eight capacity-related improvement projects to accommodate future development, as shown in Table 8-5.
Projects identified to address short-term capacity deficiencies were proposed to be constructed within 2 years of the Wastewater Interceptor Master Plan, while projects identified to address medium or long-term capacity deficiencies would be constructed within 5 to 10 years, depending on timing of need. The capacity-enhancing projects identified in the 2002 Wastewater Interceptor Master Plan have almost all been implemented by the City since 2002, with the exception of Unit Y capacity and condition projects, which are currently included in the City’s FY2021-2022/2022-2023 CIP Budget.
The City is in the process of constructing four new maintenance hole structures within the siphon and relining 4,500 feet of interceptor within the siphon reach (Unit Y). While the projects are not specifically driven by capacity-related issues, the CIP projects will address the future capacity concerns identified in the 2002 Wastewater Interceptor Master Plan for CIP project Y3.
8.5 Capital Improvement Program Schedule
As noted above, the City is planning a major update of its Wastewater Interceptor Master Plan in 2022 and will use the results of that study to update its capacity CIP schedule and budget. The City’s FY2021-2022/2022-2023 CIP includes the following capacity-related projects:
• Interceptor Capital Improvement Program Phase V - Unit Y2 (anticipated end date Spring 2022)
• Collection System Master Plan Update (FY 2022/2023)
The City will also be conducting a flow monitoring program to obtain data for use in the Wastewater Collection System Master Plan update, although the work may be conducted in conjunction with the Master Plan Update. After completion of the updated Master Plan, the schedule for additional capacity improvements will be updated and incorporated into the City’s CIP.

9 Monitoring, Measurement, and Program
Modifications
This chapter describes the City’s approach to maintaining, monitoring, and updating information relevant to evaluating the effectiveness of this SSMP.
9.1 Regulatory Requirements
The SWRCB Order No. 2006-0003-DWQ, Section D.13.ix – Monitoring, Measurement, and Program Modifications requires the City to:
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 Preventive 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.
9.2 Maintenance of Information Used to Prioritize Activities The City has multiple databases for tracking sewer system asset attributes, maintenance activities, and sewer pipeline inspection.
GIS: The City maintains information of pipelines, such as installation date, size, depth, length, material, and location, through as-built drawings and GIS. Maintenance hole inspections and pipeline linings are logged into GIS. Refer to Section 4.2.1 for details regarding GIS database.
MaintStar and InfraMap: Sewer pipeline maintenance activities are tracked using a combination of MaintStar and InfraMap. MaintStar is the data repository for sewer pipeline maintenance data while InfraMap provides the means to collect maintenance data in the field using mobile data collection devices.
GraniteNet: Sewer pipeline CCTV inspection data is collected and stored using GraniteNet software. The database documents the date, crew, and inspection data for all pipeline inspections.
IRIS: IRIS is an asset management dashboard that utilizes asset data and performs asset management calculations and analyses. The software is designed to supplement asset record systems (e.g., MMS, GIS) by performing asset management calculations that these systems cannot perform. IRIS projects the future asset R&R needs, highlights high-risk assets, calculates the appropriate budget required to mitigate the high-risk assets.
Item No.7K
City of Thousand Oaks Sewer System Management Plan
2022 Sewer System Management Plan Update
9-2 | March 2022
IRIS uses the asset database to calculate a life-cycle cost of ownership for each asset.
IRIS models financial requirements and average investment requirements for any planning horizon, and it will identify the following for each year:
• Estimated replacement cost of each asset
• Estimated total R&R budget required for each year
• Average annual R&R budget for the planning horizon
• Number of assets and estimated replacement cost budget required to address the highest risk assets
• An estimated annual budget required to sustain the future R&R after all highest risk assets have been replaced
The long-range financial needs will be viewable at any level in the asset hierarchy (i.e., by system, by facility, by asset). Where limited budget is a concern, IRIS supports the City with prioritizing investment actions based on risk. This ensures all investments are prioritized and provides a transparent and consistent way to communicate how effectively asset investments are being made.
9.3 Measuring Program Effectiveness and Monitoring
Program Implementation
The City measures and monitors SSMP Program effectiveness and implementation on an annual basis through internal performance reporting, an annual report to the Los Angeles RWQCB, and monthly updates submitted online to SWRCB. These performance measures are used to guide the City’s focus and ultimately improve the City’s effectiveness and efficiency in delivering services. Table 9-1 summarizes the key performance indicators the City uses to track SSMP Program effectiveness and implementation.

9.4 Assessing Success of Preventive Maintenance
Program
The City assesses the success of the preventive maintenance program through after- action review of sewer overflow causes and through review of the performance indicators listed in Table 9-1. Based on sewer overflow performance over the past 5 years and the on-going collection system performance summarized in the Annual Wastewater Reports Item No.7K
City of Thousand Oaks Sewer System Management Plan
2022 Sewer System Management Plan Update
March 2022 | 9-5
over the past 5 years, the City has proven to be highly effective at minimizing the number of sewer overflow events.
9.5 Sewer System Management Plan Program Updates
The City is continually reviewing SSO events and SSO performance to identify both site-specific corrective actions to address the cause of a specific sewer overflow event, as well as trends in sewer overflows leading to identification and implementation of targeted or programmatic sewer overflow reduction strategies. Based on this review, the City determines whether the SSO event is likely to be a one-time event, a potentially recurring event at that specific site, or an indicator of a trend that requires a programmatic solution. As a result of this determination, the City may choose to employ one or more of the actions identified in Table 9-2 to address or mitigate the impacts of a potential failure.

10 Sewer System Management Plan Program
Audit and Updates
The WDR requires periodic internal audits to evaluate the effectiveness of the SSMP and SSMP program implementation. This chapter details the City’s plans to conduct such internal audits.
10.1 Regulatory Requirements
The SWRCB Order No. 2006-0003-DWQ, Section D.13.x – SSMP Program Audits requires the City to:
• Conduct periodic internal audits, appropriate to the size of the system and the number of SSOs.
• At a minimum, these audits must occur every two years and a report must be prepared and kept on file
3. This audit shall focus on evaluating the effectiveness of the SSMP and the City’s compliance with the SSMP requirements identified in subsection (D.13), including identification of any deficiencies in the SSMP and steps to correct them.
10.2 Sewer System Management Plan Program Audit
Process
The City plans to perform an SSMP program audit once every 2 years. The Utilities Superintendent is responsible for initiating the SSMP program audit process. The program audit reviews performance trends and the overall SSMP Program implementation and develops a set of audit findings and proposed corrective actions.
The previous audit, input gathered throughout the term, and an assessment of current SSMP performance, are used to construct the initial draft of a new audit. This initial set of audit findings and proposed corrective actions are provided to City staff responsible for various SSMP elements for their review, comments and additions. The staff responsible for various elements of the SSMP are listed in Attachment B2.
Each SSMP element is evaluated for compliance with SSMP requirements, as well as effectiveness. Any deficiencies are identified, along with recommendations for correction.
The Utilities Superintendent oversees collection and compilation of input from the program stakeholders and documentation of the findings in the audit report. The final audit report is reviewed by the Primary Authorized Representative (Wastewater Utilities Maintenance Supervisor) before final acceptance. Audit reports and related materials are maintained in a hard copy, and an electronic file is stored on the City’s server.
Table 10-1 shows the anticipated schedule for SSMP audits and SSMP updates for the next 5 years.
3 The timeline for SSMP program audits may change if the proposed Statewide Waste Discharge Requirements General Order for Sanitary Sewer Systems is adopted. The City will monitor the adoption of the new General Order and will perform future SSMP program audits according to the timelines for compliance stipulated in the Order.

2027 5-year SSMP update planned in March 2027
Note: The schedule for SSMP program audits and SSMP updates may change if the proposed Statewide Waste Discharge Requirements General Order for Sanitary Sewer Systems is adopted.
The City will monitor the adoption of the new General Order and will perform future SSMP program audits and SSMP updates as required.
10.3 Audit Implementation and Tracking of Results
Once SSMP Program audit findings and corrective actions are finalized, City staff responsible for the various elements of the SSMP Program implementation review the audit findings to determine an appropriate course of action. The Utilities Superintendent tracks implementation progress of audit corrective actions. Any deficiencies in meeting the schedule are identified, and mitigation measures are developed and implemented to ensure corrective actions are addressed.
10.4 Sewer System Management Plan Update Process
The Utilities Superintendent and Utilities Maintenance Supervisor are responsible for ensuring the SSMP is updated when major changes to the SSMP Program implementation occur. If no major changes occur, the SSMP is updated 5 years (at a minimum) from the previous SSMP update, approval, and recertification. The results of the prior SSMP Program audit reports are factored into the SSMP update process.
Attachment J includes the Change Log documenting and authorizing the changes associated with this SSMP update.

11 Communication Program
This chapter describes the program in place to communicate with the public on the development, implementation, and performance of the SSMP and with tributary systems to the City’s sewer system.
11.1 Regulatory Requirement
SWRCB Order No. 2006-0003-DWQ, Section D.13.xi – Communication Program requires the City to:
• Communicate on a regular basis with the public on the development, implementation, and performance of its SSMP. The communication system shall provide the public the opportunity to provide input to the City as the program is developed and implemented.
• Create a plan of communication with systems that are tributary and/or satellite to the City’s sanitary sewer system.
11.2 Communications with Public
The City employs multiple modes of communication with the public regarding SSMP development, implementation, and performance. These modes include:
• City Council Meetings
• Operating Budget
• Social Media
The City’s engagement with the public provides an opportunity for the public to comment on the Sewer System Management Plan and program implementation.
11.2.1 City Council Approval
After review and approval by the Public Works Director, the SSMP is approved by City Council at a public meeting. The Sewer System Management Plan is provided as an attachment to the City Council agenda and available to the public on the City Council Agenda Public Portal:
https://toaks.primegov.com/public/portal
This provides the public with an opportunity to review and comment on the SSMP prior to approval by City Council. The public can either attend the City Council via video or watch live on Frontier Channel 3, Spectrum Channel 10, or YouTube (CTOMeetings).
The public can register to speak to the City Council at a City Council meeting either by video or phone. The public can also submit a written comment and it will be provided to Item No.7K

STATE WATER RESOURCES CONTROL BOARD
ORDER NO. 2006-0003
STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS
FOR
SANITARY SEWER SYSTEMS
The State Water Resources Control Board, hereinafter referred to as “State Water Board”, finds that:
1. All federal and state agencies, municipalities, counties, districts, and other public entities that own or operate sanitary sewer systems greater than one mile in length that collect and/or convey untreated or partially treated wastewater to a publicly owned treatment facility in the State of California are required to comply with the terms of this Order. Such entities are hereinafter referred to as “Enrollees”.
2. Sanitary sewer overflows (SSOs) are overflows from sanitary sewer systems of domestic wastewater, as well as industrial and commercial wastewater, depending on the pattern of land uses in the area served by the sanitary sewer system. SSOs often contain high levels of suspended solids, pathogenic organisms, toxic pollutants, nutrients, oxygen-demanding organic compounds, oil and grease and other pollutants. SSOs may cause a public nuisance, particularly when raw untreated wastewater is discharged to areas with high public exposure, such as streets or surface waters used for drinking, fishing, or body contact recreation. SSOs may pollute surface or ground waters, threaten public health, adversely affect aquatic life, and impair the recreational use and aesthetic enjoyment of surface waters.
3. Sanitary sewer systems experience periodi c failures resulting in discharges that may affect waters of the state. There are many factors (including factors related to geology, design, construction methods and materials, age of the system, population growth, and system operation and maintenance), which affect the likelihood of an SSO. A proactive approach that requires Enrollees to ensure a system-wide operation, maintenance, and management plan is in place will reduce the number and frequency of SSOs within the state. This approach will in turn decrease the risk to human health and the environment caused by SSOs.
4. Major causes of SSOs include: grease blockages, root blockages, sewer line flood damage, manhole structure failures, vandalism, pump station mechanical failures, power outages, excessive storm or ground water inflow/infiltration, debris blockages, sanitary sewer system age and construction material failures, lack of proper operation and maintenance, insufficient capacity and contractor- caused damages. Many SSOs are preventable with adequate and appropriate facilities, source control measures and operation and maintenance of the sanitary sewer system.
Item No.7K
State Water Resources Control Board Order No. 2006-0003 Page 2 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06
SEWER SYSTEM MANAGEMENT PLANS
5. To facilitate proper funding and management of sanitary sewer systems, each Enrollee must develop and implement a system-specific Sewer System Management Plan (SSMP). To be effective, SSMPs must include provisions to provide proper and efficient management, operation, and maintenance of sanitary sewer systems, while taking into consideration risk management and cost benefit analysis. Additionally, an SSMP must contain a spill response plan that establishes standard procedures for immediate response to an SSO in a manner designed to minimize water quality impacts and potential nuisance conditions.
6. Many local public agencies in Calif ornia have already developed SSMPs and implemented measures to reduce SSOs. These entities can build upon their existing efforts to establish a comprehensive SSMP consistent with this Order.
Others, however, still require technical assistance and, in some cases, funding to improve sanitary sewer system operation and maintenance in order to reduce SSOs.
7. SSMP certification by te chnically qualified and experienced persons can provide a useful and cost-effective means for ensuring that SSMPs are developed and implemented appropriately.
8. It is the State Water Boar d’s intent to gather additional information on the causes and sources of SSOs to augment existing information and to determine the full extent of SSOs and consequent public health and/or environmental impacts occurring in the State.
9. Both uniform SSO reporting and a centralized statewide electronic database are needed to collect information to allow the State Water Board and Regional Water Quality Control Boards (Regional Water Boards) to effectively analyze the extent of SSOs statewide and their potential impacts on beneficial uses and public health. The monitoring and reporting program required by this Order and the attached Monitoring and Reporting Program No. 2006-0003, are necessary to assure compliance with these waste discharge requirements (WDRs).
10. Information regarding SSOs must be provided to Regional Water Boards and other regulatory agencies in a timely manner and be made available to the public in a complete, concise, and timely fashion.
11. Some Regional Water Boards have issued WDRs or WDRs that serve as National Pollution Discharge Elimination System (NPDES) permits to sanitary sewer system owners/operators within their jurisdictions. This Order establishes minimum requirements to prevent SSOs. Although it is the State Water Board’s intent that this Order be the primary regulatory mechanism for sanitary sewer systems statewide, Regional Water Boards may issue more stringent or more Item No.7K
State Water Resources Control Board Order No. 2006-0003 Page 3 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 prescriptive WDRs for sanitary sewer systems. Upon issuance or reissuance of a Regional Water Board’s WDRs for a system subject to this Order, the Regional Water Board shall coordinate its requirements with stated requirements within this Order, to identify requirements that are more stringent, to remove requirements that are less stringent than this Order, and to provide consistency in reporting.
REGULATORY CONSIDERATIONS
12. California Water Code section 13263 provides that the State Water Board may prescribe general WDRs for a category of discharges if the State Water Board finds or determines that:
• The discharges are produced by the same or similar operations; • The discharges involve the same or similar types of waste; • The discharges require the same or similar treatment standards; and • The discharges are more appropriately regulated under general discharge requirements than individual discharge requirements.
This Order establishes requirements for a class of operations, facilities, and discharges that are similar throughout the state.
13. The issuance of general WDRs to the Enrollees will:
a) Reduce the administrative burden of issuing individual WDRs to each Enrollee;
b) Provide for a unified statewide ap proach for the reporting and database tracking of SSOs;
c) Establish consistent and unifo rm requirements for SSMP development and implementation;
d) Provide statewide co nsistency in reporting; and
e) Facilitate consistent enforcement for violations.
14. The beneficial uses of surface waters that can be impaired by SSOs include, but are not limited to, aquatic life, drinking water supply, body contact and non- contact recreation, and aesthetics. The beneficial uses of ground water that can be impaired include, but are not limited to, drinking water and agricultural supply.
Surface and ground waters throughout the state support these uses to varying degrees.
15. The implementation of requirements set forth in this Order will ensure the reasonable protection of past, present, and probable future beneficial uses of water and the prevention of nuisance. The requirements implement the water quality control plans (Basin Plans) for each region and take into account the environmental characteristics of hydrographic units within the state. Additionally, the State Water Board has considered water quality conditions that could reasonably be achieved through the coordinated control of all factors that affect Item No.7K
State Water Resources Control Board Order No. 2006-0003 Page 4 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 water quality in the area, costs associated with compliance with these requirements, the need for developing housing within California, and the need to develop and use recycled water.
16. The Federal Clean Water Act largely prohibits any discharge of pollutants from a point source to waters of the United States except as authorized under an NPDES permit. In general, any point source discharge of sewage effluent to waters of the United States must comply with technology-based, secondary treatment standards, at a minimum, and any more stringent requirements necessary to meet applicable water quality standards and other requirements.
Hence, the unpermitted discharge of wastewater from a sanitary sewer system to waters of the United States is illegal under the Clean Water Act. In addition, many Basin Plans adopted by the Regional Water Boards contain discharge prohibitions that apply to the discharge of untreated or partially treated wastewater. Finally, the California Water Code generally prohibits the discharge of waste to land prior to the filing of any required report of waste discharge and the subsequent issuance of either WDRs or a waiver of WDRs.
17. California Water Code section 13263 requires a water board to, after any necessary hearing, prescribe requirements as to the nature of any proposed discharge, existing discharge, or material change in an existing discharge. The requirements shall, among other things, take into consideration the need to prevent nuisance.
18. California Water Code section 13050, subdivision (m), defines nuisance as anything which meets all of the following requirements:
a. Is injurious to health , or is indecent or offensive to the senses, or an obstruction to the free use of property, so as to interfere with the comfortable enjoyment of life or property.
b. Affects at the same time an entire community or neighborhood, or any considerable number of persons, although the extent of the annoyance or damage inflicted upon individuals may be unequal.
c. Occurs during, or as a result of, the treatment or disposal of wastes.
19. This Order is consistent with State Water Board Resolution No. 68-16 (Statement of Policy with Respect to Maintaining High Quality of Waters in California) in that the Order imposes conditions to prevent impacts to water quality, does not allow the degradation of water quality, will not unreasonably affect beneficial uses of water, and will not result in water quality less than prescribed in State Water Board or Regional Water Board plans and policies.
20. The action to adopt this General Order is exempt from the California Environmental Quality Act (Public Resources Code §21000 et seq.) because it is an action taken by a regulatory agency to assure the protection of the environment and the regulatory process involves procedures for protection of the environment. (Cal. Code Regs., tit. 14, §15308). In addition, the action to adopt Item No.7K
State Water Resources Control Board Order No. 2006-0003 Page 5 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 this Order is exempt from CEQA pursuant to Cal.Code Regs., title 14, §15301 to the extent that it applies to existing sanitary sewer collection systems that constitute “existing facilities” as that term is used in Section 15301, and §15302, to the extent that it results in the repair or replacement of existing systems involving negligible or no expansion of capacity.
21. The Fact Sheet, which is incorporated by reference in the Order, contains supplemental information that was also considered in establishing these requirements.
22. The State Water Board has notified all affected public agencies and all known interested persons of the intent to prescribe general WDRs that require Enrollees to develop SSMPs and to report all SSOs.
23. The State Water Board conducted a public hearing on February 8, 2006, to receive oral and written comments on the draft order. The State Water Board received and considered, at its May 2, 2006, meeting, additional public comments on substantial changes made to the proposed general WDRs following the February 8, 2006, public hearing. The State Water Board has considered all comments pertaining to the proposed general WDRs.
IT IS HEREBY ORDERED, that pursuant to California Water Code section 13263, the Enrollees, their agents, successors, and assigns, in order to meet the provisions contained in Division 7 of the California Water Code and regulations adopted hereunder, shall comply with the following:
A. DEFINITIONS
1. Sanitary sewer overflow (SSO) - Any overflow, spill, release, discharge or diversion of untreated or partially treated wastewater from a sanitary sewer system. SSOs include:
(i) Overflows or releases of untreated or partially treated wastewater that reach waters of the United States;
(ii) Overflows or releases of untreated or partially treated wastewater that do not reach waters of the United States; and
(iii) Wastewater backups into buildings and on private property that are caused by blockages or flow conditions within the publicly owned portion of a sanitary sewer system.
2. Sanitary sewer system – Any system of pipes, pump stations, sewer lines, or other conveyances, upstream of a wastewater treatment plant headworks used to collect and convey wastewater to the publicly owned treatment facility.
Temporary storage and conveyance facilities (such as vaults, temporary piping, construction trenches, wet wells, impoundments, tanks, etc.) are considered to be part of the sanitary sewer system, and discharges into these temporary storage facilities are not considered to be SSOs.
Item No.7K

C. PROHIBITIONS
1. Any SSO that results in a discharge of untreated or partially treated wastewater to waters of the United States is prohibited.
2. Any SSO that results in a discharge of untreated or partially treated wastewater that creates a nuisance as defined in California Water Code Section 13050(m) is prohibited.
D. PROVISIONS
1. The Enrollee must comply with all cond itions of this Order. Any noncompliance with this Order constitutes a violation of the California Water Code and is grounds for enforcement action.
2. It is the intent of the State Water Board that sanitary sewer systems be regulated in a manner consistent with the general WDRs. Nothing in the general WDRs shall be:
(i) Interpreted or applied in a manner inconsistent with the Federal Clean Water Act, or supersede a more specific or more stringent state or federal requirement in an existing permit, regulation, or administrative/judicial order or Consent Decree;
(ii) Interpreted or applied to authoriz e an SSO that is illegal under either the Clean Water Act, an applicable Basin Plan prohibition or water quality standard, or the California Water Code;
(iii) Interpreted or applied to prohibit a Regional Water Board from issuing an individual NPDES permit or WDR, superseding this general WDR, for a sanitary sewer system, authorized under the Clean Water Act or California Water Code; or
(iv) Interpreted or applied to supersede any more specific or more stringent WDRs or enforcement order issued by a Regional Water Board.
3. The Enrollee shall take all feasible steps to eliminate SSOs. In the event that an SSO does occur, the Enrollee shall take all feasible steps to contain and mitigate the impacts of an SSO.
4. In the event of an SSO, the Enrollee sh all take all feasible steps to prevent untreated or partially treated wastewater from discharging from storm drains into Item No.7K
State Water Resources Control Board Order No. 2006-0003 Page 8 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 flood control channels or waters of the United States by blocking the storm drainage system and by removing the wastewater from the storm drains.
5. All SSOs must be reported in accor dance with Section G of the general WDRs.
6. In any enforcement action, the State and/or Regional Water Boards will consider the appropriate factors under the duly adopted State Water Board Enforcement Policy. And, consistent with the Enforcement Policy, the State and/or Regional Water Boards must consider the Enrollee’s efforts to contain, control, and mitigate SSOs when considering the California Water Code Section 13327 factors. In assessing these factors, the State and/or Regional Water Boards will also consider whether:
(i) The Enrollee has complied with the r equirements of this Order, including requirements for reporting and developing and implementing a SSMP;
(ii) The Enrollee can identify the cause or likely cause of the discharge event;
(iii) There were no feasible alternatives to the discharge, such as temporary storage or retention of untreated wastewater, reduction of inflow and infiltration, use of adequate backup equipment, collecting and hauling of untreated wastewater to a treatment facility, or an increase in the capacity of the system as necessary to contain the design storm event identified in the SSMP. It is inappropriate to consider the lack of feasible alternatives, if the Enrollee does not implement a periodic or continuing process to identify and correct problems.
(iv) The discharge was exceptional, unintentional, temporary, and caused by factors beyond the reasonable control of the Enrollee;
(v) The discharge could have been prevented by the exercise of reasonable control described in a certified SSMP for:
• Proper management, operation and maintenance;
• Adequate treatment facilities, sanitary sewer system facilities, and/or components with an appropriate design capacity, to reasonably prevent SSOs (e.g., adequately enlarging treatment or collection facilities to accommodate growth, infiltration and inflow (I/I), etc.);
• Preventive maintenance (including cleaning and fats, oils, and grease (FOG) control);
• Installation of adequate backup equipment; and
• Inflow and infiltration prevention and control to the extent practicable.
(vi) The sanitary sewer system design capacity is appropriate to reasonably prevent SSOs.
Item No.7K
State Water Resources Control Board Order No. 2006-0003 Page 9 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 (vii) The Enrollee took all reasonable steps to stop and mitigate the impact of the discharge as soon as possible.
7. When a sanitary sewer overflow occurs, the Enrollee shall take all feasible steps and necessary remedial actions to 1) control or limit the volume of untreated or partially treated wastewater discharged, 2) terminate the discharge, and 3) recover as much of the wastewater discharged as possible for proper disposal, including any wash down water.
The Enrollee shall implement all remedial actions to the extent they may be applicable to the discharge and not inconsistent with an emergency response plan, including the following:
(i) Interception and rerouting of untreated or partially treated wastewater flows around the wastewater line failure;
(ii) Vacuum truck recovery of sani tary sewer overflows and wash down water;
(iii) Cleanup of debris at the overflow site;

STATE OF CALIFORNIA
WATER RESOURCES CONTROL BOARD
ORDER NO. WQ 2013-0058-EXEC
AMENDING MONITORING AND REPORTING PROGRAM
FOR
STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS FOR
SANITARY SEWER SYSTEMS
The State of California, Water Resources Control Board (hereafter State Water Board) finds:
1. The State Water Board is authorized to prescribe statewide general Waste Discharge Requirements (WDRs) for categories of discharges that involve the same or similar operations and the same or similar types of waste pursuant to Water Code section 13263(i).
2. Water Code section 13193 et seq. requires the Regional Water Quality Control Boards (Regional Water Boards) and the State Water Board (collectively, the Water Boards) to gather Sanitary Sewer Overflow (SSO) information and make this information available to the public, including but not limited to, SSO cause, estimated volume, location, date, time, duration, whether or not the SSO reached or may have reached waters of the state, response and corrective action taken, and an enrollee's contact information for each SSO event. An enrollee is defined as the public entity having leg a! authority over the operation and maintenance of, or capital improvements to, a sanitary sewer system greater than one mile in length.
3. Water Code section 13271, et seq. requires notification to the California Office of Emergency Services (Cal OES), formerly the California Emergency Management Agency, for certain unauthorized discharges, including SSOs.
4. On May 2, 2006, the State Water Board adopted Order 2006-0003-DWQ, "Statewide Waste Discharge Requirements for Sanitary Sewer Systems"1 (hereafter SSS WDRs) to comply with Water Code section 13193 and to establish the framework for the statewide SSO Reduction Program.
5. Subsection G.2 of the SSS WDRs and the Monitoring and Reporting Program (MRP) provide that the Executive Director may modify the terms of the MRP at any time.
6. On February 20, 2008, the State Water Board Executive Director adopted a revised MRP for the SSS WDRs to rectify early notification deficiencies and ensure that first responders are notified in a timely manner of SSOs discharged into waters of the state.
7. When notified of an SSO that reaches a drainage channel or surface water of the state, Cal OES, pursuant to Water Code section 13271 (a)(3), forwards the SSO notification information2 to local government agencies and first responders including local public health officials and the applicable Regional Water Board.

and Cal OES is duplicative. To address this, the SSO notification requirements added by the February 20, 2008 MRP revision are being removed in this MRP revision.
8. In the February 28, 2008 Memorandum of Agreement between the State Water Board and the California Water and Environment Association (CWEA), the State Water Board committed to re designing the CIWQS3 Online SSO Database to allow "event" based SSO reporting versus the original "location" based reporting. Revisions to this MRP and accompanying changes to the CIWQS Online SSO Database will implement this change by allowing for multiple SSO appearance points to be associated with each SSO event caused by a single asset failure.
9. Based on stakeholder input and Water Board staff experience implementing the SSO Reduction Program, SSO categories have been revised in this MRP. In the prior version of the MRP, SSOs have been categorized as Category 1 or Category 2. This MRP implements changes to SSO categories by adding a Category 3 SSO type. This change will improve data management to further assist Water Board staff with evaluation of high threat and low threat SSOs by placing them in unique categories (i.e., Category 1 and Category 3, respectively). This change will also assist enrollees in identifying SSOs that require Cal OES notification.
10. Based on over six years of implementation of the SSS WDRs, the State Water Board concludes that the February 20, 2008 MRP must be updated to better advance the SSO Reduction Program4 objectives, assess compliance, and enforce the requirements of the SSS WDRs.
IT IS HEREBY ORDERED THAT:
Pursuant to the authority delegated by Water Code section 13267{f), Resolution 2002-0104, and Order 2006-0003-DWQ, the MRP for the SSS WDRs (Order 2006-0003-DWQ) is hereby amended as shown in Attachment A and shall be effective on September 9, 2013.

Procedure for Wastewater-Related Spills and Overflows
PROCEDURES:
Regardless of size, the primary focus of overflows, spills and collection (main line) breaks should be on public and employee safety. During any wastewater emergency, follow the steps included below.
Appendix B includes additional contact information and a list of emergency equipment. Appendix C includes a flow chart for quick-reference by staff.
The Municipal Service Center (805) 449-2499 may be informed of a spill and authorized staff (such as the Utilities Maintenance Supervisor during normal hours or standby phone after normal hours) are notified. Normal working hours are Monday through Thursday from 6:30 AM to 5 PM. Other forms of communication that can indicate a potential SSO include SCADA alarms from lift stations or alarms from one of the ten stationary flow meters throughout the sanitary sewer collection system. SCADA alarms directly alert field staff during working hours or personnel on standby phone after hours, while flow meter alarms alert US3 , in which US3 then verifies then notifies the City.
Upon notification, responding staff shall arrive at the scene, perform preliminary assessment, take appropriate action, and communicate results to the designated supervisor. Upon notification of a potential sewer overflow, a City responder is dispatched onsite with the goal to arrive within 30 minutes.
The Utilities Maintenance Supervisor (Supervisor) or Crew Leader shall respond immediately to any emergencies. Crew Leaders or field staff may investigate other service requests or less-
urgent complaints...
The Supervisor or Crew Leader shall evaluate the situation and make the following determinations:
i. City service area or Triunfo Water and Sanitation District (under contract with Ventura Regional Sanitation District) - All wastewater emergencies occurring outside the City's wastewater service area are included in Triunfo Water and Sanitation District and will be the responsibility of that District; the City of Thousand Oaks will only respond as a mutual-assistance agency when requested and resources are deemed available. The Triunfo Water and Sanitation District and/or its contractor (VRSD) will be responsible for making the appropriate notifications to the necessary agencies and directing City personnel activities if applicable through mutual aid.
Ventura Regional Sanitation District Contact Info:

ii. Public vs. private Issue – The City of Thousand Oaks ownership and responsibility does not include sewer laterals. Private property situations will be handled by the Building Division of the Community Development Department (CDD). Public facilities such as; parks, libraries, Los Robles Greens golf cour se, etc. must be handled through CDD (Appendix C). City crews will typically check the City main to determine responsibility by opening upstream and downstream sewer main manholes. City staff will attempt to contain Item No.7K

The City is operating under two different sets of requirements for collection system spill water quality monitoring, spill notification and spill reporting with one set provided in the Statewide General Waste Discharge Requirements for Sanitary Sewer Systems (WDR) and the other set provided in Order R4-2019-0137 (Hill Canyon Treatment Plant NPDES permit)1. The following list summarizes the City’s approach regarding the two sets of requirements.
1 The City summarized these two different sets of requirements in an email to the Regional Water Quality Control Board staff Andrew Choi and Veronica Cuevas on 8/17/2021 and scheduled a meeting to discuss these requirements. The City received an email cancelling the meeting and identified that Regional Water Quality Control Board staff would work on a response. No response was received by the City at the time of developing this document.
Item No.7K
Procedure for Wastewater-Related Spills and Overflows
o The City will perform water quality monitoring for all Category 1 SSOs per Order R4- 2019-0137. The City will identify in CIWQS when sampling is completed, which parameters were sampled, and attach the monitoring results. o The City will provide notifications and reporting of collection system SSOs per the WDR and this reporting will be through CIWQS. Hill Canyon Treatment Plan unauthorized discharge notification and reporting will be per Order R4-2019-0137.
Environmental Compliance staff and HCTP Laboratory Supervisor shall be notified of any discharge. HCTP Laboratory Supervisor is responsible for NPDES compliance related to Order R4-2019-0137 (Hill Canyon Treatment Plant NPDES permit) including annual report for NPDES regarding SSOs.
For discharges reaching an active waterway (Category 1 spills) the HCTP Lab Supervisor will oversee water quality monitoring per the Water Quality Monitoring Program Plan (Appen dix D).
The HCTP Laboratory Supervisor will arrange posting notices as directed by Ventura County Environmental Health Division (VCEHD). Typically, signs shall be posted at the spill site and as necessary to reasonably warn the public if a spill occurs and there is a possibility of wastewater entering recreational water or other waterways where the public may come in contact.
Additional contacts that may be notified on a case- by-case basis or utilized for improved response are included in Appendix B.
Prepare an appropriate plan and address the spill. This should take into consideration all reasonable steps to minimize or prevent any discharge that has a reasonable likelihood of adversely affecting human health or the environment. Addressing the spill shou ld generally adhere to the following procedures:
i. Secure the area and restrict access to only authorized and relevant personnel. Traffic control and area security may include signage, caution tape, traffic cones and truck mounted arrow board.
ii. Typically, relieve any stoppage immediately with Hydro truck or bypass the stoppage (or pipeline break) by pumping from an upstream manhole to a downstream manhole. iii. Containment should begin in a safe and orderly manner, before any repair work. Use sandbags, dirt, absorbent towels or other materials where appropriate. Main concern is to clear the stoppage.
iv. Dam the spill or watercourse so all contaminated water is contained. All attempts must be made to prevent any amount from reaching an active watercourse or storm drain, or from impairing public access or health.
v. Pump any spillage including solid and liquid materials to a downstream manhole, or vacuum spillage for transport. Normally, if the spill is in the gutter, procedure is to vacuum residual out of the gutter, wash down area and then vacuum what is washed down.
Remove contaminated dirt if spill is not on a street. Chemicals are not typically applied for disinfection.
vi. Refer to storm drain atlas to follow storm drain routes for vacuuming any amount that reached a storm drain.
Item No.7K
Procedure for Wastewater-Related Spills and Overflows
vii. If necessary and when large volumes are released, use portable pumps and bypassing or vactor trucks to recover the spill.
The Supervisor will request or dispatch any equipment, tools, or safety equipment necessary to address the s ituation, contain the spill, break any stoppage, and/or commence repair/cleanup activities.
After the spill has been addressed, the Supervisor or Crew Leader will initiate any additional repair or cleanup activities needed. City equipment will be mobilized, and contractors and suppliers should be contacted as necessary and appropriate. i. After sewer main spill recovery, the line may be televised to evaluate condition of line and cause of stoppage. Sewer main may become a hot spot for cleaning or recommended for replacement/rehabilitation.
Lift Station Failures
i. Olsen Road Lift Station includes a containment tank that can contain flow for approximately 72 hours under typical flow rates in the event of lift station failure. The lift station may also be by-passed using a 6-inch pump owned by the City.
ii. Lawrence Drive Lift Station includes a by-pass that can transfer flow to the Unit E gravity main in the event of lift station failure.
Record Keeping
i. Maintain individual SSO records for a minimum of 5 years from the date of the SSO including but not limited to:
a. Complaint records documenting how the enrollee responded to all notifications of possible or actual SSOs, both during and after business hours, including complaints that do not result in SSOs. Each complaint record shall, at a minimum, include the following information:
5. Date, time, and method of notification.
6. Date and time the complainant or informant first noticed the SSO.
7. Narrative description of the complaint, including any information the caller can provide regarding whether or not the complainant or informant reporting the potential SSO knows if the SSO has reached surface waters, drainage channels or storm drains.

SANITARY SEWER OVERFLOW ONLINE REPORTING
Both uniform SSO reporting and a centralized statewide electronic database are needed to collect information to allow the State Water Board and Regional Water Quality Control Boards (Regional Water Boards) to effectively analyze the extent of SSOs statewide and their potential impacts on beneficial uses and public health. The monitoring and reporting program required by the Order and the attached Monitoring And Reporting Program Order No. WQ 2013-0058-EXEC, are necessary to assure compliance with these waste discharge requirements (WDRs). All information required to be reported into the CIWQS Online SSO Database shall be certified by the authorized individual (designee), having responsibility for the overall operation of the regulated facility or activity. Note:
this requires designee registration with the State in the CIWQS database. This designated person is also known as the legally responsible official (LRO). An enrollee may have more than one LRO.

To comply with subsection D of the State Water Resources Control Board Order No. WQ 2013- 0058-EXEC, the City has developed and implemented this SSO Water Quality Monitoring Program to assess impacts from SSOs to for Category 1 SSOs to surface waters.
The SSO Water Quality Monitoring Program required by the SSS WDR, shall include, at minimum:
1. Contain protocols for water quality monitoring.
2. Account for spill travel time in the surface water and scenarios where monitoring may not be possible (e.g. safety, access restrictions, etc.).
3. Require water quality analyses for ammonia and bacterial indicators to be performed by an accredited and certified laboratory.
4. Require monitoring instruments and devices used to implement the SSO Water Quality Monitoring Program to be properly maintained and calibrated, including any records to document maintenance and calibration, as necessary, to ensure their continued accuracy.
5. Within 48 hours of the enrollee becoming aware of the SSO, require water quality sampling for, at a minimum, the following constituents:
i. Ammonia.
ii. Appropriate Bacterial indicator(s) per the applicable Basin Plan water quality objective or Regional Board direction which may include total and fecal coliform, enterococcus, and e- coli.
Additionally, for Category 1 SSOs of 50,000 gallons or more, an SSO technical report is required and must be submitted within 45 calendar days from the SSO end date.

All City staff shall be aware and follow all safety precautions in order to comply with this Water Quality Monitoring Program. Therefore, all staff needs to take into account where monitoring will not be possible which may include:
• Heavy rain / storm events where access points may be compromised; • Flooding around low areas; or
• Fast moving waters.
City staff should evaluate and keep safety first when encountering these scenarios and are encouraged to exercise proper judgment to limit health risk.
ESTIMATION OF SPILL TRAVEL TIME
The following method is recommended to estimate spill travel direction:
• Take visual ft/sec measurement from above, based on a floating debris, to estimate the number of feet the debris has traveled in seconds. (Note: If the first measurement is uncertain, this time estimate may be performed three to five times, and the values averaged to determine Item No.7K
Procedure for Wastewater-Related Spills and Overflows
the estimate travel time. The velocity in the upper portion of the water body can then be calculated by dividing the measured distance by the average time.) •
WATER QUALITY SAMPLING
In the event that that a Category 1 SSO reaches surface waters or flowing drainage channel tributary to a larger body of water, City staff should take samples within 48 hours. Environmental Compliance staff are notified.
Laboratory staff, Environmental Compliance staff and crews may be involved in sampling efforts.
The purpose of water quality sampling is to determine the nature and extent of the impact of the SSO. Water quality sampling typically includes the following unless otherwise directed by Ventura County Environmental Health Division (VCEHD) or other regulators:
• Ammonia. Performed by Hill Canyon Treatment Plant (HCTP) Laboratory. • Appropriate Bacterial indicator. The HCTP Laboratory performs total and fecal coliform.
The HCTP Laboratory is ELAP certified for these tests identified above.
Samples should be collected as stipulated in Water Quality Sampling Procedure below. Lab sample procedures and the locations should be recorded on an area map depicting each location of sampling. The samples should be collected as follows:
• First sample at the discharge location
• Second sample up stream of discharge location approximately 500 feet up stream from the discharge location.
• Third sample approximately 1,000 feet down stream of the discharge location.
After collecting the samples, the samples should be tested at HCTP Laboratory . This sampling and testing should continue until the results from the lab indicates that they are back to baseline levels.
Collaboration with VCEHD or other regulators and sampling should continue until they determine that the sampling is no longer needed.
WATER QUALITY SAMPLING EQUIPMENT
The following guideline describes the equipment and supplies to be stocked and readily available for any water quality sampling event.
a. Sterile sample bottles
b. Ice chest with ice/ blue ice
c. Chain of custody forms
d. Ball point pens and label ing tapes
e. Sampling pole
f. Syringes
g. Gloves
Item No.7K
Procedure for Wastewater-Related Spills and Overflows
h. Other PPE (i.e. rubber boots, apron, mask, etc.)
Laboratory staff should ensure that there are adequate quantities of sample containers to accommodate sampling locations.
WATER QUALITY SAMPLING PROCEDURE
Call Laboratory Supervisor to notify them about the sampling event.
1. Disposable un-powdered gloves are recommended for sample collection to protect you and to assure the integrity of the samples. Disposable gloves should be changed at each sampling location.
2. Determine the correct location for sample collection.
3. Samples for bacteria/coliform analysis shall be collected in a sterile, colilert container. Sampler will submerge container, midstream of the effluent, point top into the effluent, remove cap and fill container to fill line, or as close as possible in an effort to allow air space in the container for mixing. Label sample bottle with:
a. sampling site
b. date and time sampled
c. sampler first and last name
4. Keep the samples packed on blue ice or equivalent for delivery to the laboratory.
5. Deliver all samples to the laboratory within 4 hrs.
6. Fill out Chain of Custody (COC) with the same information to match the sample bottles.
Complete the COC as thoroughly as possible with you and your supervisor’s names and phone numbers. Be sure to relinquish the COC with your signature, printed name, date, and time.
WATER QUALITY ANALYSIS-PROTOCOLS
Typical monitoring parameters may include: Ammonia, total and fecal coliform bacteria, or other analyses as required.
Laboratory:
• All samples will be sent to the Laboratory. The laboratory methods will be performed according to the laboratory’s Standard Operation Procedures (SOPs).
Maintenance and Calibration of Monitoring Instruments and Devices:
• In order to be accredited and maintain their certification, the HCTP Laboratory follows stringent quality assurance and quality control protocols that includes regular monitoring, calibration and maintenance of their equipment. The frequency of monitoring and calibration varies based on equipment type and method requirements. Records of the calibration receipts are kept on file and readily available up on request.
