City of Pasadena Sewer System Management Plan Page ix
Purpose and Background
In December 2022, the State of California’s Water Resources Control Board (SWRCB) adopted Order Number WQ 2022-0103-DWQ that updated General WDRs for sanitary sewer systems designed to convey sewage greater than one (1) mile in length . The order became effective on June 5, 2023. This order supersedes the previous Order Number 2006-0003-DWQ and all amendments thereafter (i.e., Order No. WQ 2013-0058-EXEC). The WDR requires that all enrolled agencies develop a Sewer System Management Plan (SSMP) that describes the activities of the enrollee in managing, operating, and maintaining their sanitary sewer collection system. The purpose of the Order is to prevent sanitary sewer spills and to provide a plan and schedule for measures to be implemented for spill prevention including measures to effectively clean up and report spills. A copy of the reissued 2022 WDR is included in Appendix A.
The reissued WDR includes directives for owners and operators of sanitary sewer systems to demonstrate adequate and efficient management, operation, and maintenance of the sanitary sewer system. Generally, the WDR requires that:
In the event of a spill, all feasible steps are taken to control the released volume and prevent untreated wastewater from entering storm drains, creeks, etc.
If a spill occurs, it must be reported to the SWRCB using California Integrated Water Quality System (CIWQS), the online reporting system developed by the SWRCB.
An SSMP with all mandatory elements be developed and approved by the governing body that owns or is responsible for the operation of the sanitary sewer system. The SSMP must include provisions to provide proper and efficient management, operation, and maintenance of the sanitary sewer system.
Spills often contain high levels of suspended solids, pathogenic organisms, toxic pollutants, nutrients, oxygen - demanding organic compounds, oil and grease and other pollutants. Spills may cause a public nuisance and/or a public health hazard 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. Spills may pollute surface or ground waters, threaten public health, adversely affect aquatic life, and impair the recreational use and aesthetic enjoyment of surface waters.
Sanitary sewer systems experience periodic failures resulting in discharges that may affect waters of the state.
There are many factors (including factors related to geology, design, construction methods and materials, age of the system, population growth, and system operation and maintenance), or excessive infiltration and inflow (I/I) which affect the likelihood of a spill. A proactive approach that requires agencies to ensure a system-wide operation, maintenance, and management plan is in place that will reduce the number and frequency of spills within the state.
This approach will in turn decrease the risk to human health and the environment caused by spills.

This enables a unified collaboration and flow of information between staff members. This department provides resources in responding to spills and access to storm sewer systems during spill events. Communication and training with staff Element 3: Legal Authority
City of Pasadena Sewer System Management Plan Page 18
allow both agencies to know their part in responding to spills and recognizing areas at risk, develop strategies in containing and preventing spills, and reduce risks of cross contamination. Additionally, the City’s personnel maintain knowledge of the locations of storm water collection facilities that are nearby sewer facilities.
Installation of sewer and storm water facilities are coordinated to prevent unintentional cross connections. To ensure that cross-connections between the City’s sanitary sewer and storm drain systems do not occur, the City maintains records of the alignments of both systems and when they were constructed. Additionally, the City coordinates with LACFCD in the event of a spill.
No connections to either system are allowed without a permit being first obtained from the City’s Public Works Department. Each such permit issued is to contain the following information:
• Line to which the connection was made
• Location of connection on the line
• Depth of the connection at property line
All connections to either system are inspected by a City inspector to ensure that all the above information is accurate and that the connection is made in accordance with established standards. Public Works inspectors , under the Engineering Division, are responsible for inspecting all connections within the public rights-of-way.

This chapter describes the City’s ability to properly manage, operate, and maintain all parts of the sanitary sewer system owned and operated by the City, and that the system operators (including employees, contractors, or other agents) are adequately trained and possess adequate knowledge, skills, and abilities.
Requirements:
D.4. OPERATION AND MAINTENANCE PROGRAM: The Plan must include the items listed below that are appropriate and applicable to the Enrollee’s system.
4.1. Updated Map of Sanitary Sewer System: An up-to-date map(s) of the sanitary sewer system, and procedures for maintaining and providing State and Regional Water Board staff access to the map(s). The map(s) must show gravity line segments and manholes, pumping facilities, pressure pipes and valv es, and applicable stormwater conveyance facilities within the sewer system service area boundaries.
4.2. Preventive Operation and Maintenance Activities : A scheduling system and a data collection system for preventive operation and maintenance activities conducted by staff and contractors.
The scheduling system must include:
• Inspection and maintenance activities;
• Higher-frequency inspections and maintenance of known problem areas, including areas with tree root problems;
• Regular visual and closed-circuit television (CCTV) inspections of manholes and sewer pipes. The data collection system must document data from system inspection and maintenance activities, including system areas/components prone to root-intrusion potentially resulting in system backup and/or failure.
4.3. Training: In-house and external training provided on a regular basis for sanitary sewer system operations and maintenance staff and contractors. The training must cover:
• The requirements of the General Order;
• The Enrollee’s Spill Emergency Response Plan procedures and practice drills; • Skilled estimation of spill volume for field operators; and • Electronic CIWQS reporting procedures for staff submitting data.
4.4. Equipment Inventory : An inventory of sewer system equipment, including the identification of critical replacement and spare parts.
Element 4: Operation and Maintenance Program
City of Pasadena Sewer System Management Plan Page 22
4.1 Updated Map of Sanitary Sewer System
The City has created a comprehensive, customized, electronic based Geographic Information System (GIS) sewer collection system map, showing all pipeline segments and manholes within the City’s jurisdictional boundary. The City will prioritize keeping the GIS up-to-date and will establish a formal procedure for updating it when new assets are added to the City’s collection system or when existing assets are abandoned. The City has a full-time GIS/CAD technician that maintains the City’s GIS. The City’s engin eering staff will improve communication with the Department of Information Technology to ensure new or rehabilitated sewer system assets are accurately reflected in the GIS.
At the current time, digital maps are available indicating general pipelin e, lift station, and manhole locations. The City’s iMap database’s manhole and sewer pipeline IDs are used to store information in the City’s scheduled preventive maintenance, repair, and cleaning database, such as work order history . The City’s maintenance crew uses Lucity for accessing sewer line information and recording details of repairs and cleanings.
The City is responsible for maintaining the stormwater system and does have access to maps of the nearby storm water inlets and pipelines, as these are City-owned facilities.
The City will provide State and Regional Water Board staff with access to the map(s) through submitting the sewer geodatabase to the State and Regional Water Boards as well as including the map within this SSMP Update, which will be submitted to CIWQS once a year. An updated map of the sewer collection system is included in Appendix E.
4.2 Preventive Operation and Maintenance Activities
The City currently performs in -house preventive operation and maintenance activities. This includes periodic cleaning, regular inspection of pump stations, and investigation of customer complaints.
4.2.1 Sewer Cleaning & CCTV Inspection
The City has five dedicated crew s, made up of two staff each, for sewer line cleaning. A regular schedule is performed to ensure that the entire system is cleaned annually by zone with hot spots cleaned at least quarterly.
The City’s maintenance crew, along with th e current active CIP contractor, treat s the sewer system for roots and addresses any emergency repairs.
CCTV inspection has recently been performed on an as-needed basis rather than on a regular schedule by the street maintenance crew. If a problem is identified in the CCTV inspection, the Street Maintenance Supervisor notifies the Capital Improvements Engineer. The engineer documents the defects found and includes the repair into the Annual Sewer Relining and Point Repair Project, which is a component of the Capital Improvement Program (CIP).
The City plans to develop and implement a regular CCTV inspection schedule to ensure th at the entire system is CCTV inspected every 7 years (or approximately 14% a year). The City is planning to achieve this goal by developing a CCTV inspection schedule, including areas prone to root-intrusion. These inspections will be collected and filed in the City’s system.
4.2.2 Lift Station Maintenance
Two of the City’s sewer lift stations (Rosemont and Busch Garden) are maintained through an ongoing contract with MultiTech Pumps & Accessories, Co. The City has contracted Sigma to maintain one lift station (Rockwood). The Element 4: Operation and Maintenance Program
City of Pasadena Sewer System Management Plan Page 23
City has access to two backup generators in the case of a power outage. The contractors responsible for lift station maintenance are available 24 hours a day to service the pump stations as needed.
4.2.3 Odor Control
The City has received approximately 16 isolated odor complaints in the past 3 years , most of which were investigated and addressed. Although t he City has no official odor control program in place , it responds to complaints by inspecting the condition of the pipe sections and ensuring proper flow.
4.2.4 Corrosion Control
Over 90 percent of the pipe material in the City’s collection system is vitrified clay pipe (VCP), which is inert and does not need corrosion control. The remaining portion of the collection system is concrete pipe, cast iron pipe (CIP), or ductile iron pipe (DIP) which is not inert and does need corrosion control. To prevent corrosion, the City undertakes numerous relining projects as part of the Annual Sewer Relining and Point Repair Project within the annual Capital Improvement Program.
4.2.5 Investigation of Customer Complaints
The City promptly addresses customer complaints about the sewer system, which are typically related to sewer back-ups. The collection system staff responds immediately by conducting CCTV inspections of the lines and making necessary repairs to the affected sections or manholes. This response i nvolves assessing the complaint and resolving the issue efficiently.
4.2.6 Data Collection
City staff document their cleaning s and CCTV inspections electronically, filing them on the City’s server. They are committed to continuing to thoroughly document all maintenance activities. The City intends to add this information to their GIS database. The City plans to continue documenting and monitoring system deficiencies with recurrent issues based off complaints, field inspections, and CCTV inspection results.
4.3 Training
The City sends staff to trainings on the SSMP and all aspects of the Spill Emergency Response Plan (SERP) one to two times per year. The City also has multiple tailgate safety meetings each year. Currently these tailgate training meetings are focused on certain elements of the SSMP, such as emergency bypass training, equipment inventory, and routine sewer maintenance. The City will continue to review its training program to meet the demands of maintaining the sewer system. The City is planning on performing semiannual meetings to review sections of the SSMP. The City intends to cover the full SSMP over a year long period. The City will continue to implement training on the requirements of the General Order, Spill Emergency Response Plan procedures and practice drills, s killed estimation of spill volume for field operators, and electronic CIWQS reporting procedures for staff submitting data.
Currently, the City’s active CIP contractor does not conduct formal sewer spill response training. The contractor handles spill responses by following the documented SERP. The City plans to include formal SERP and SSMP training to its renewed contract with the active CIP contractor.
The City is committed to all trainings being documented and the records kept readily accessible.
Element 4: Operation and Maintenance Program
City of Pasadena Sewer System Management Plan Page 24
4.4 Equipment Inventory
The City maintains an equipment inventory. All sewer pipeline equipment and replacement parts are stored at the City’s Yards.
The City is responsible for ensuring that their equipment is kept in proper working condition and that backup supplies are available. The City ensures that their sewer trucks are in good working condition. The City has access to two backup generators in the case of a power outage.
The City contracts MultiTech Pumps & Accessories, Co. and Signa Mechanical for sewer pump station maintenance.
Both service providers are responsible for managing their own equipment inventory, such as spare parts for pumps.
The City contracts Herc Rentals, Inc. in case additional equipment and parts are needed for emergency repairs.
The City will create a database for spare parts and track the current inventory, ensuring that staff are updating this as repairs are made and parts are ordered. The equipment and spare parts will be checked regularly to make sure that they are in working order for use in emergencies.

6.1 Background
The City of Pasadena (City) Department of Public Works (DPW) operates and maintains its own sanitary collection system. The City’s sanitary collection system consists of approximately 328 miles of gravity pipelines within its 23.1 Element 6: Spill Emergency Response Plan
City of Pasadena Sewer System Management Plan Page 28
square mile sewer service area. The City’s wastewater collection system conveys untreated wastewater to Los Angeles County Sanitation District’s (LACSD) trunk sewer system via 120 separate connections.
The City of Pasadena collection system is subject to regulation and permitted under the General Order WQ 2022 - 0103-DWQ and is identified under WDID 4SSO10416. The City will annually review and assess the effectiveness of the Spill Emergency Response Plan ( SERP) and update as necessary. The latest version of the SERP, updated in 2024, is available in Appendix F.
Note: During the 10-year period extending from January 1, 2014 to December 31, 2024, the City experienced thirty- one (31) spills from within its sanitary sewer collection system.
6.2 Known Collection System Problems
The following are currently known collection system problems within the City’s system:
1. Heavy root intrusion – Tree roots infiltrate sewer pipes in search of moisture, often entering through small cracks or loose joints. Older pipes made from materials like clay, concrete, or metal are particularly susceptible to root intrusion.
2. Old and deteriorated pipes and manholes - the sanitary sewer system ranges in age from 18-138 years, with an average age of 91 years.
3. Manhole base erosion – There can be many reasons for manhole base erosion, such as heavy traffic loads, water infiltration, and hydrogen sulfide corrosion. Regular maintenance is crucial to prevent further degradation and ensure longevity of manholes.
4. Manhole cover failures - There are various possible reasons for manhole cover failures, such as heavy traffic loads, susceptibility to corrosion, and general wear and tear.
5. Cracks and fractures throughout sewer mains - Existing sewers are mostly clay pipes, which can crack as they deteriorate with age and by earth movement.
6.3 Causes of Sewer Backups
The following are currently known causes for sewer backups within the City’s system:
1. Debris -- Debris (i.e. rags, gloves, construction debris/materials, plastic bags, etc.) has caused frequent backups due to lack of scouring velocity in the laterals and main lines.
2. Root infiltration -- Root infiltration has been identified as a cause of sewer backups in laterals.
3. Grease – Grease has been identified as a cause of sewer backups in laterals.
6.4 Preventative Maintenance
Refer to Section 4.2 for the City’s preventative maintenance program.
Element 6: Spill Emergency Response Plan
City of Pasadena Sewer System Management Plan Page 29
6.5 Overflow Detection
Detection of a sanitary sewer spill may occur in numerous ways:
1. If an outside party calls in to report a spill, the Collection System Crew Supervisor in the Public Works/Street Maintenance Division or his/her designee shall be notified immediately. a. If this occurs after hours, the caller is directed to the Police Dispatch who will notify the on-call personnel.
2. The Collection System Crew Supervisor, or his/her designee, upon determining that the sewer problem is the City's responsibility, will mobilize necessary City personnel and equipment to the spill location and contact the City's active sewer maintenance/cap ital improvement program (CIP) services contractor for emergency service, if needed.
3. If there is a risk or threat to public safety, the Collection System Crew Supervisor will notify the Public Works Superintendent, or his/her designee, to oversee the response.

The City’s Legally Responsible Official (LRO), or his/her designee, shall report the spill event to the State and Regional Water Board and other agencies if applicable (such as County Health Officer, County Environmental Health Agency, Regional Water Board, and/or State Office of Emergency Services).
Section 2.4 of this SSMP details the chain of communication for reporting spills and contact numbers for these points of contact.
Pre-planned coordination and collaboration with the City’s stormwater staff will be implemented prior, during, and after a spill event.
6.6 Initial Spill Response
6.6.1 Containment Procedures
The City’s immediate response to a spill prioritizes containment. Following containment, City staff perform recovery operations, implement any necessary bypass procedures, and conduct emergency repairs. If the City crews require additional support, they may contact the City’s active pipeline CIP contractor s for emergency support. The City’s active CIP contractor s vary per fiscal year. The City’s current emergency pipeline contractor s and contact information are as follows:
Active CIP Contractor Southwest Pipeline and Trenchless Corp 310-329-8717 Active CIP Contractor GRBCon, Inc. 626-699-2380
Element 6: Spill Emergency Response Plan
City of Pasadena Sewer System Management Plan Page 30
The City’s crew will attempt to keep the spill in as small an area as possible. If reasonable, the crew should attempt to keep the spill in the street and out of the storm drain or other surface water bodies. To ensure the spill is contained, the crew will use the following methods:
1. Contain the spill immediately. Contain sewage on the ground using a temporary or manmade berm , if applicable.
2. Isolate, contain, and/or divert sewage flow from any open channels and storm drain structures using sandbags, inflatable dams, or soil barriers. Sandbags or absorbent material can be used around the spill to collect the sewage and prevent it from spreading.
3. Protect storm drains by blocking upstream and downstream storm drain openings or divert ing flow with sandbags and plastic sheets, prioritizing containment within the street or hard surface. Set up traffic control per the WATCH Manual. If traffic or crowd control is required, call police dispatch at (626) 744-4501.
4. Should the spill take place in an off-road area not normally accessible to the public (i.e. field, etc.) the crew will use any reasonable means to pool the flow in that area for recovery.
5. Capture the spill.
a. If necessary, berm flow and start pumping into the closest clear and flowing manhole. b. Contact the Public Works Superintendent at (626) 744-4808. c. Evaluate the sewer system spill rate. The most senior employee on scene will evaluate the spill rate.
6. Determine the source and/or cause of the spill (i.e., evaluate type and amount of debris, illegal activities, etc.). City staff may need to observe downstream manholes to establish the location of the cause of the spill such as a blockage.
a. If the cause is determined to be private ly generated, and the damage is limited to the property, upon request the City may provide a list of cont ractors to the private owner to assist with clean up and/or pipe clearance.
7. Clear the obstruction and restore flow.
a. Restore system flow by hydro jetting, rodding, open cut excavati ng, or any other means to clear the blockage or failure point.
b. If necessary, set up a hydro jetter downstream of the blockage and jet upstream from a clear manhole. c. Capture as much of the material causing the blockage as possible. d. If unable to relieve the blockage, request immediate assistance from additional staff and appropriate equipment.
e. If still unable to clear the blockage, request immediate assistance with the establishment of bypass pumping and CCTV support to determine the problem.
f. If engineering consultation is necessary, contact the Public Works Superintendent (or City Engineer if he/she cannot be reached). He/she shall initiate an emergency work order to the City’s on -call contractor to repair the pipe.
g. Ensure the downstream manholes are clear and flowing.
8. Should the flow be too much to be contained in the street and is identified as a danger to the public the crew will allow the flow to enter the storm drain or catch basin. The crew will plug upstream and downstream portions of impacted storm drains or catch basins and recover it from that point using a vacuum truck and/or set up a diversion to a downstream manhole.
9. If necessary, request additional personnel, materials, supplies, or equipment from Departments of Police, Fire and Health that will expedite and minimize the impact of the spill, such as traffic diversion, crowd control, and street closure.
Element 6: Spill Emergency Response Plan
City of Pasadena Sewer System Management Plan Page 31
10. Upon determining and correcting the source and/or cause of the spill, a sample of the sewage may be taken as evidence for possible analysis.
11. All sewage shall be captured and discharged into the closest clear and flowing manhole. Any contaminated materials unfit for the sewer and likely to cause blockages shall be transported to a local landfill for ultimate disposal. See Section 6.7 for treatment in dry or wet weather conditions and collection instructions.
12. Estimate volume of the spill as detailed in Section 6.13.2.
13. If required, safely perform all spill sampling as detailed in the Water Quality Monitoring Plan.
14. Notify regulatory agencies about the spill and follow any additional instructions they may have.
6.6.2 Sewer Bypassing
If the spill involves damage to or collapse of a pipeline, or the spill has been determined to be prolonged for any reason, and a bypass is necessary:
1. Bypass action is to be administered, as soon as conditions safely allow, by City personnel at the location where the damaged pipeline occurs.
2. Place appropriate pumps and hoses to keep sewage in the sewer line. Appropriate measures shall be taken to determine the proper size and number of pumps required to effectively handle the sewage flow. The City contracted Herc Rentals, Inc. for equipment rental in case additional pumps, piping, or hoses are required to conduct a bypass. The contact information for Herc Rentals, Inc. is provided below:
On-Call Equipment Rental Company Phone

7 Sewer Pipe Blockage
Control Program
This chapter discusses the City’s sewer pipe blockage control measures, including identification of problem areas, focused cleaning, and source control.
Requirements:
D.7. SEWER PIPE BLOCKAGE CONTROL PROGRAM: The Sewer System Management Plan must include procedures for the evaluation of the Enrollee’s service area to determine whether a sewer pipe blockage control program is needed to control fats, oils, grease, rags and debris. If the Enrollee determines that a program is not needed, the Enrollee shall provide justification in its Plan for why a program is not needed. The procedures must include, at minimum:
• An implementation plan and schedule for a public education and outreach program that promotes proper disposal of pipe-blocking substances;
• A plan and schedule for the disposal of pipe -blocking substances 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 substances generated within a sanitary sewer system service area; • The legal authority to prohibit discharges to the system and identify measures to prevent spills and blockages;
• Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, best management practices requirements, recordkeeping and reporting requirements;
• Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the fats, oils, and grease ordinance; • An identification of sanitary sewer system sections subject to fats, oils, and grease blockages and establishment of a cleaning schedule for each section; and • Implementation of source control measures for all sources of fats, oils, and grease reaching the sanitary sewer system for each section identified above.
Fats, oils, and grease (FOG), rags and debris have been identified as one source of blockages in the City’s collection system. The City implements a Sewer Pipe Blockage Control Program, which aims to prevent the discharge of FOG, rags, and debris into the sanitary sewer and storm drain systems. The program also aims to prevent spills and illegal discharge into the storm drain, subsequently improving public health and safety , protecting waterways, and reducing sewer maintenance costs.
Over the last 10 years (2015 -2024), there have been twenty -nine (29) spills total, seven (7) spills of which are known to have been attributed to fats, oils, grease, rags, and debris. The City formally tracks sanitary sewer system sections subject to FOG blockages and cleans each segment on a quarterly basis. Appendix I provides a map showing the FOG cleaning runs across the city.
Element 7: Sewer Pipe Blockage Control Program
City of Pasadena Sewer System Management Plan Page 44
Chapter 8.14 (Grease and Oil Disposal Ordinance) of the City Municipal Code regulates the disposal of food service establishment cooking greases so as to prevent blockages in the city's sewer system caused by the collection of grease, thereby forcing raw sewage to escape through manhole covers, surface drainage systems or other inappropriate exit points.
All industrial dischargers are required to obtain a wastewater discharge permit from the City. All new restaurants are required to install a grease interceptor and must receive approval by the Department of Planning and Development (DPD) and Pasadena Public Health Department. Such establishments may request a variance to allow for the installation o f only a grease trap or an alternative pre -treatment technology. Any device installation must conform to the latest California Plumbing Code (CPC) and are inspected by the Pasadena Public Health Department for conformance with the latest CPC.
Chapter 13.24 (Sewer Construction and Maintenance) of the City Municipal Code prohibit s illicit discharges and identify measures to prevent spills and blockages to the City’s sanitary sewer system. It provides the legal authority for site inspections and enforcement of violations of industrial wastewater discharge regulations and enforcing the 2002 FOG ordinance (see Appendix I).
In January 2023, the City’s Stormwater Program Administrator embarked on a public outreach campaign with industrial and commercial facilities regarding the importance of N ational Pollutant Discharge Elimination System (NPDES) and FOG inspection programs to ensure public health safety, improve water quality and the environment.
To reduce the impacts to municipal infrastructure , t he City developed a formal FOG inspection program for inspecting and enforcing the 2002 FOG ordinance.supported by a new fee assessment.
As of July 1st, 2024, all commercial and industrial facilities whose activities produce FOG, are required to be inspected bi-annually by the City. The inspection will provide educational awareness on proper FOG disposal and will enforce activities found to be in violation of City Code and ordinances through the Code Enforcement staff. The City created a procedure for when the sewer staff notices any problems with the system arising from FOG, and debris, and to coordinate with the discharger to create mitiga tion strategies. The City also ensures all inspections and enforcement measures are being formally tracked in the Stormwater Multiple Application and Report Tracking System (SMARTs).
To continue educating City facilities and the public on proper FOG disposal practices and its importance to protect public health and water quality, the City developed Pasadena-specific NPDES and FOG Fact Sheets that are provided along with other NPDES inspection -related materials during the bi -annual inspection and distributed in annual business license renewal s. Department of Public Works is currently developing a public website that will house these educational links and other related materials on proper FOG disposal and overall best management practices (BMPs) for industrial and commercial facilities.
Additionally, California adopted Senate Bill 1383 (SB 1383) which requires communities to reduce organic waste disposal, such as food waste, by 75% by 2025. To achieve this mandate, the City launched its Curbside Organics Recycling program in 2022. Food waste sh all no longer be going in the trash - residential refuse customers must include bagged food waste in their Yard Waste containers. Businesses and multi-family properties are also required to subscribe and participate in organics collection services through City approved franchise haulers. These organics collection services may contribute to a decreased amount of food waste, including FOG, being disposed of down the drain. Additional information can be found at https://www.cityofpasadena.net/public-works/recycling- resources/organics-recycling/sb-1383-information-and-resources/ The City also participates in the Used Oil Payment Program offered by the Department of Resources Recycling and Recovery (CalRecycle), which provides funding for used oil and used oil filter collection and recycling programs. The funding allocated to the City are used to promote used oil recycling through advertising, Oil Filter Exchange Events, Element 7: Sewer Pipe Blockage Control Program
City of Pasadena Sewer System Management Plan Page 45
and our Curbside Used Motor Oil Pick-Up Program. The City aims to hold Oil Filter Exchange Events four to six times per year, depending on the funding and staffing availability, at local auto parts retailers. The goal of the event is to reward residents for recycling their used oil filters and provide them with oil change supplies that promote recycling and prevent spills. Customers who bring in used oil filters receive a coupon and exchange their used oil filters at the store for up to two new oil filters. The City promotes these events (and used oil recycling in general) via ads in local news outlets, City social media accounts, the City website, and flyers. Appendix I includes a sample flyer from one of the events promoting this program. Residents with City of Pasadena refuse service can also call our City Service Center (CSC) to schedule a pickup of their used motor oil and filters. City staff will deliver up to 5 containers to store the oil and pick them up at their regularly scheduled refuse pickup day by appointment only. The City also dedicates a section of their Waste Management and Recycling webpage to Used Motor Oil and Oil Filter Recycling.
This includes information on the above services, a list of Certified Collection Centers in Pasadena, and emphasizes that motor oil should never be poured into storm drains. Additional information can be found at https://www.cityofpasadena.net/public-works/recycling-resources/universal-hazardous-waste-recycling/used- motor-oil-filter-certified-collection-centers/.
Lastly, the City created maintenance requirements, best management practices requirements, recordkeeping and reporting requirements, and design standards for the removal of grease interceptors for wastewater discharge permit holders. Businesses or residences can contact the City about FOG disposal through CSC. CSC is a centralized service to help Pasadena residents connect with the City. It is available via web, LiveChat, mobile app and phone to assist in answering questions about City programs, services and events. They a re the main point of contact for residents reporting issues related to sewers or storm drains. Link to this application can be found at https://www.cityofpasadena.net/city-service-center/.

8 System Evaluation, Capacity
Assurance, and Capital Improvements
This chapter discusses the City’s capacity management measures, including the most recent Master Plan and recommended capacity improvement projects.
Requirements:
D.8. SYSTEM EVALUATION, CAPACITY ASSURANCE AND CAPITAL IMPROVEMENTS: The Plan must include procedures and activities for:
• Routine evaluation and assessment of system conditions; • Capacity assessment and design criteria;
• Prioritization of corrective actions; and
• A capital improvement plan.
8.1 System Evaluation and Condition Assessment: The Plan must include procedures to:
• Evaluate the sanitary sewer system assets utilizing the best practices and technologies available; • Identify and justify the amount (percentage) of its system for its condition to be assessed each year; • Prioritize the condition assessment of system areas that:
o Hold a high level of environmental consequences if vulnerable to collapse, failure, blockage, capacity issues, or other system deficiencies;
o Are located in or within the vicinity of surface waters, steep terrain, high groundwater elevations, and environmentally sensitive areas;
o Are within the vicinity of a receiving water with a bacterial -related impairment on the most current Clean Water Act section 303(d) List;
• Assess the system conditions using visual observations, video surveillance and/or other comparable system inspection methods;
• Utilize observations/evidence of system conditions that may contribute to exiting of sewage from the system which can reasonably be expected to discharge into a water of the State; • Maintain documents and recordkeeping of system evaluation and condition assessment inspections and activities; and
• Identify system assets vulnerable to direct and indirect impacts of climate change, including but not limited to: sea level rise; flooding and/or erosion due to increased storm volumes, frequency, and/or intensity; wildfires; and increased power disruptions.
8.2. Capacity Assessment and Design Criteria: The Plan must include procedures to identify system components that are experiencing or contributing to spills caused by hydraulic deficiency and/or limited capacity, including procedures to identify the appropriate hydraulic capacity of key system elements for:
• Dry-weather peak flow conditions that cause or contributes to spill events; Element 8: System Evaluation, Capacity Assurance, and Capital Improvements
City of Pasadena Sewer System Management Plan Page 48
• The appropriate design storm(s) or wet weather events that causes or contributes to spill events; • The capacity of key system components; and
• Identify the major sources that contribute to the peak flows associated with sewer spills.
The capacity assessment must consider:
• Data from existing system condition assessments, system inspections, system audits, spill history, and other available information;
• Capacity of flood -prone systems subject to increased infiltration and inflow, under normal local and regional storm conditions;
• Capacity of systems subject to increased infiltration and inflow due to larger and/or higher -intensity storm events as a result of climate change;
• Increases of erosive forces in canyons and streams near underground and aboveground system components due to larger and/or higher-intensity storm events; • Capacity of major system elements to accommodate dry weather peak flow conditions, and updated design storm and wet weather events; and
• Necessary redundancy in pumping and storage capacities.
8.3. Prioritization of Corrective Action: The findings of the condition assessments and capacity assessments must be used to prioritize corrective actions. Prioritization must consider the severity of the consequences of potential spills.
8.4. Capital Improvement Plan: The capital improvement plan must include the following items:
• Project schedules including completion dates for all portions of the capital improvement program; • Internal and external project funding sources for each project; and • Joint coordination between operation and maintenance staff, and engineering staff/consultants during planning, design, and construction of capital improvement projects; and Interagency coordination with other impacted utility agencies.
8.1 System Evaluation and Condition Assessment
The City’s last sewer system master plan was performed in 2019. The master plan included a model of the collection system. Hydraulic simulations were performed for the present (2019), 2035 and build out time frames. Surcharged pipes were identified and recommendations made for upgrade.
Currently, the City performs CCTV inspection on an as-needed basis. If a problem is identified in the CCTV inspection, this is tracked by the maintenance crew and sent to the Engineering Department so it can be added to the Annual Sewer Relining and Point Repair Project so that it can be scheduled for repair.
The City has budgeted a sewer system master plan to be performed in fiscal year 2029. In this upcoming master plan, the City plans to utilize CCTV evaluation to assess their sewer system, identify capacity deficiencies in their system, and identify potential repair and replacement projects. The City plans to establish a regular CCTV inspection and cleaning program with a goal to CCTV inspect and clean the entire system every seven (7) years (or approximately 14% a year).
Element 8: System Evaluation, Capacity Assurance, and Capital Improvements
City of Pasadena Sewer System Management Plan Page 49
With the recent sewer rate increase approved by the City Council in the summer of 2024, the City will be able to address known issues associated with structural damage, corrosion, roots, and manhole degradation.
8.2 Capacity Assessment and Design Criteria
The 2019 Master Plan included a capacity evaluation and identified capacity-related improvement projects for the collection system only. The capacity assessment completed as part of the City’s Sewer Master Plan was based on hydraulic modeling of the City’s collection system under current (2019) and future design flows. Surcharged pipes were identified, and these pipe segments were recommended for upgrade.
City requirements state that new developments proposing a net increase of 50 Equivalent Dwelling Units (EDUs) or more must be simulated in the City’s sewer collection system hydraulic model to ensure the new connection does not negatively impact the existing system.
The City has not experienced any sanitary sewer overflows due to hydraulic deficiencies in the sewer system in the past four years. Likewise, modeling of the City’s sewer system conducted during the preparation of the 2019 Sewer Master Plan indicated no overflows were anticipated due to hydraulic deficiencies.
The City plans to include a hydraulic model in the 2029 master plan that evaluates the sewer system’s ability to convey existing and future peak flows. Additionally, this model will identify areas with limited capacity and the need for system improvements and rehabilitation based on any capacity issues identified.
8.3 Prioritization of Corrective Action
Previously, the City assessed recurring issues identified during CCTV inspections and prioritized them into specific projects. Additionally, problem areas within the sewer system were prioritized for lining as part of the Annual Sewer Relining and Point Repair Project.
8.4 Capital Improvement Plan
For capital improvements, the City has currently been performing rehabilitation and replacement projects as condition-related issues arise. If a pipeline condition-related problem is identified in the CCTV inspection, a work order is produced, and the repair is added to the annual program.
Pipelines needing immediate attention would be schedule d for rehabilitation or replacement immediately by the City’s CIP Contractor. All other rehabilitation or replacements will be generated into a project after consultant review.
The City completed four sewer relining and point repair projects from their 2019 master plan, including multiple relining projects. The City is anticipating pump station upgrade projects in the next fiscal year.
The City rehabilitated or replaced approximately 34,200 LF of pipeline in 2021, 28,250 LF in 2022, and 7,300 LF in 2023 and is anticipating to line 25,000 LF in 2024/2025.
The City only uses local funds from sewer facility charges for sewer construction and maintenance.
Once potential projects are identified in the 2029 master plan, schedules with completion dates will be included for all portions of the capital improvement program. Funding sources will also be identified in the master plan. Any coordination necessary between operation and maintenance staff, and engineering staff/consultants during planning, design, and construction of capital improvement projects will be outlined.

9 Monitoring, Measurement and
Program Modifications
This section of the SSMP discusses parameters the City tracks to monitor the success of the SSMP and how the City plans to keep the SSMP current.
Requirements:
D.9. MONITORING, MEASUREMENT AND PROGRAM MODIFICATIONS : The Plan must include an Adaptive Management section that addresses Plan-implementation effectiveness and the steps for necessary Plan improvement, including:
• Maintaining relevant information, including audit findings, to establish and prioritize appropriate Plan activities;
• Monitoring the implementation and measuring the effectiveness of each Plan Element; • Assessing the success of the preventive operation and maintenance activities; • Updating Plan procedures and activities, as appropriate, based on results of monitoring and performance evaluations; and
• Identifying and illustrating spill trends, including spill frequency, locations and estimated volumes.
In the past, the City did not have a formal process for tracking the success of SSMP elements. As issues arose and elements changed, the City tracked certain segments of each element of the SSMP such as organizational changes and system maintenance. Currently, the City is motivated to be proactive about spill prevention and understand how tracking their SSMP elements will improve efficacy of this goal.
The City will perform regular tracking of the SSMP elements and their effectiveness. The City will develop a database, or similar tool, to maintain specific information related to the SSMP, as a central repository for changes to the SSMP and regularly track the success of SSMP elements, including the preventative maintenance activities noted above. The City will evaluate whether SSMP elements have changed so that changes can be documented in a Change Log to include the specific change, the date of the change and the name of the person making the change.
The Change Log is included in Appendix J. Procedures and activities will be updated based on the tracking and assessment methods described therein. Table 9-1 details a schedule for evaluating the Monitoring, Measurement, and Program Modifications.

The City will use the specific monitoring parameters listed in Table 9 -2 and documented on the tracking sheet included in Appendix K to assist in completion of the annual SSMP Audit described in Plan Element 10, Internal Audits. The City will also continue to collect data for all performance measures currently tracked. This additional information that the City collects, such as customer complaints and length of pipe cleaned, will be used to support or further evaluate the success and limitations of the SSMP as needed.
The City tracked scheduled preventative maintenance, repairs, and cleaning activities and is committed to improve on the consistency of this tracking, including beginning to track system deficiencies with recurrent issues to further support the success of the SSMP. The City has consistently track ed the components listed in Table 9 -3 to quantitatively determine the effectiveness of preventive operation and maintenance activities. Using this data and comparing it to spill data shown in Table 9-4, the current preventative operation and maintenance activities appear to be successful in reducing spills. However, once the City establishes a regular CCTV inspection program, they are confident this will ensure spills are further minimized by reaching their goal to CCTV inspect the entire system every seven (7) years (or approximately 14% a year), as well as performing regular rehabilitation and replacement projects to rectify condition- and capacity-deficient pipelines and infrastructure.

10 Internal Audits
This chapter discusses the City’s SSMP auditing program.
Requirements:
D.10. INTERNAL AUDITS: The Plan shall include internal audit procedures, appropriate to the size and performance of the system, for the Enrollee to comply with section 5.4 (Sewer System Management Plan Audits) of the General Order.
The reissued State Water Resources Control Board’s Order Number WQ 2022-0103-DWQ requires that an agency conduct an internal audit of its SSMP at least once every three (3) years. The audit is to evaluate how the City has developed and implemented each of the eleven elements of the SSMP and how each element is functioning to assist in the prevention of sanitary sewer spills. The audit report shall be kept on file at the City offices and uploaded to the online California Integrated Water Quality System (CIWQS) database within 6 months after the end of the 3- year audit period. Any deficiencies found during the audit are addressed and corrected.
The due dates for the City’s SSMP and SSMP audits can be found here using the City’s WDID (4SSO10416):
https://www.waterboards.ca.gov/water_issues/programs/sso/lookup/ In 2024, the City contracted with Dudek to complete its audit and work closely with the City’s staff to review the SSMP, its implementation, and the effectiveness of the City’s efforts in reducing spills.
The City plans to complete audit requirements and due dates corresponding to the original audit cycle. The City’s next SSMP audit is to be completed and uploaded to CIWQS by 5/2/2027. During this next audit, the City will review the progress of SSMP elements and their success, areas of improvement in implementing the SSMP and preventing spills, evaluate whether they are tracking monitoring, measurement, and program modifications under Element 9, provide a description of system improvements from the previous year, and provide a description and schedule of system improvements for the upcoming year. Audit findings and recommendations will be incorporated into future SSMP Updates.

o Spills and discharges resulting in closures of public areas, or that enter a source of drinking water, and o The development, implementation, and update of its Plan, including opportunities for public input to Plan implementation and updates.
• Owners/operators of systems that connect into the Enrollee’s system, including satellite systems, for:
o System operation, maintenance, and capital improvement-related activities.
The City maintains a website (https://www.cityofpasadena.net) to inform the public about City activities. The City’s website is an effective communication channel for providing alerts and news to the public. The main page of the website provides important announcements, agendas and minutes for City Council meetings , and other key information for City residents.
Once approved by the council on June 2, 2025 , the City will maintain its SSMP on the City’s Public Works section of their website (https://www.cityofpasadena.net/public-works/). The link to the document on the City’s website will include opportunities for public input on plan implementation and updates. The Pasadena City Council incorporates opportunities for public input regarding any sewer system concerns at its Board meetings. The City has presented the 2019 Master Sewer Plan in several public meetings and has provided the public an opportunity to comment on its findings and financial implications related to sewer use fees.
The City plans to communicate with LACSD regularly about any changes with its local industrial waste pretreatment and/or FOG program to enhance local source control efforts and improve local wastewater effluent as appropriate.
The City will use a section of the website to notify the public of important upcoming activities related to sewer system management in addition to information on spills and discharges requiring closures of public areas or that enter a source of drinking water. The City has a Public Information Office through the City Manager’s Office responsible for communicating to the public regarding the SSMP, as well as any spills and discharges. The City plans to hold public awareness events and presentations regarding SSMP implementation and updates.

STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
4 1. INTRODUCTION
This General Order regulates sanitary sewer systems designed to convey sewage. For the purpose of this Order, a sanitary sewer system includes, but is not limited to, pipes, valves, pump stations, manholes, siphons, wet wells, diversion structures and/or other pertinent infrastructure, upstream of a wastewater treatment plant headworks. A sanitary sewer system includes:
• Laterals owned and/or operated by the Enrollee;
• Satellite sewer systems; and/or
• Temporary conveyance and storage facilities, including but not limited to temporary piping, vaults, construction trenches, wet wells, impoundments, tanks and diversion structures.
Sewage is untreated or partially treated domestic, municipal, commercial and/or industrial waste (including sewage sludge), and any mixture of these wastes with inflow or infiltration of stormwater or groundwater, conveyed in a sanitary sewer system.
Sewage contains high levels of suspended solids, non-digested organic waste, pathogenic bacteria, viruses, toxic pollutants, nutrients, oxygen-demanding organic compounds, oils, grease, pharmaceuticals, and other harmful pollutants.
For the purpose of this General Order, a spill is a discharge of sewage from any portion of a sanitary sewer system due to a sanitary sewer system overflow, operational failure, and/or infrastructure failure. Sewage and its associated wastewater spilled from a sanitary sewer system may threaten public health, beneficial uses of waters of the State, and the environment.
This General Order serves as statewide waste discharge requirements and supersedes the previous State Water Resources Control Board (State Water Board) Order 2006-0003-DWQ and amendments thereafter. All sections and attachments of this General Order are enforceable by the State Water Board and Regional Water Quality Control Boards (Regional Water Boards). Through this General Order, the State Water Board requires an Enrollee to:
• Comply with federal and state prohibitions of discharge of sewage to waters of the State, including federal waters of the United States;
• Comply with specifications, and notification, monitoring, reporting and recordkeeping requirements in this General Order that implement the federal Clean Water Act, the California Water Code (Water Code), water quality control plans (including Regional Water Board Basin Plans) and policies;
• Proactively operate and maintain resilient sanitary sewer systems to prevent spills; • Eliminate discharges of sewage to waters of the State through effective implementation of a Sewer System Management Plan;
• Monitor, track, and analyze spills for ongoing system-specific performance improvements; and
• Report noncompliance with this General Order per reporting requirements.
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
5 An Enrollee is a public, private, or other non-governmental entity that has obtained approval for regulatory coverage under this General Order, including:
• A state agency, municipality, special district, or other public entity that owns and/or operates one or more sanitary sewer systems:
o greater than one (1) mile in length (each individual sanitary sewer system); o one (1) mile or less in length where the State Water Board or a Regional Water Board requires regulatory coverage under this Order; or • A federal agency, private company, or other non-governmental entity that owns and/or operates a sanitary sewer system of any size where the State Water Board or a Regional Water Board requires regulatory coverage under this Order in response to a history of spills, proximity to surface water, or other factors supporting regulatory coverage.
For the purpose of this Order, a sanitary sewer system includes only systems owned and/or operated by the Enrollee.
2. REGULATORY COVERAGE AND APPLICATION REQUIREMENTS
2.1. Requirements for Continuation of Existing Regulatory Coverage To continue regulatory coverage from previous Order 2006-0003-DWQ under this General Order, within the 60-days-prior-to the Effective Date of this General Order, the Legally Responsible Official of an existing Enrollee shall electronically certify the Continuation of Existing Regulatory Coverage form in the online California Integrated Water Quality System (CIWQS) Sanitary Sewer System Database. The Legally Responsible Official will receive an automated CIWQS-issued Notice of Applicability email, confirming continuation of regulatory coverage under this General Order. All regulatory coverage under previous Order 2006-0003-DWQ will cease on the Effective Date of this Order.
An Enrollee continuing existing regulatory coverage is not required to submit a new application package or pay an application fee for enrollment under this General Order.
The annual fee due date for continued regulatory coverage from previous Order 2006-0003-DWQ to this General Order remains unchanged.
A previous Enrollee of Order 2006-0003-DWQ that fails to certify the Continuation of Existing Regulatory Coverage form in the online CIWQS database by the Effective Date of this Order is considered a New Applicant, and will not have regulatory coverage for its sanitary sewer system(s) until:
• A new application package for system(s) enrollment is submitted per section 2.2 (Requirements for New Regulatory Coverage) below; and
• The new application package is approved per section 2.2.2 (Approval of Application Package (For New Applicants Only)).
2.2. Requirements for New Regulatory Coverage
No later than 60 days prior to commencing and/or assuming operation and maintenance responsibilities of a sanitary sewer system, a duly authorized representative that

2.3. Regulatory Coverage Transfer
Regulatory coverage under this General Order is not transferable to any person or party except after an existing Enrollee submits a written request for a regulatory coverage transfer to the Deputy Director, at least 60 days in advance of any proposed system ownership transfer. The written request must include a written agreement between the existing Enrollee and the new Enrollee containing:
• Acknowledgement that the transfer of ownership is solely of an existing system with an existing waste discharge identification (WDID) number; • The specific ownership transfer date in which the responsibility and regulatory coverage transfer between the existing Enrollee and the new Enrollee becomes effective; and
• Acknowledgement that the existing Enrollee is liable for violations occurring up to the ownership transfer date and that the new Enrollee is liable for violations occurring on and after the ownership transfer date.
The Deputy Director will consider approval of the written request. If approved, the Deputy Director will issue a Notice of Applicability letter which serves as an approved transfer of regulatory coverage to the new Enrollee.
3. FINDINGS
3.1. Legal Authorities
3.1.1. Federal and State Regulatory Authority
The objective of the Clean Water Act is to restore and maintain the chemical, physical, and biological integrity of the waters of the United States (33 U.S.C. 1251). The Water Code authorizes the State Water Board to implement the Clean Water Act in the State and to protect the quality of all waters of the State (Water Code sections 13000 and 13160).
3.1.2. Discharge of Sewage
A discharge of untreated or partially treated sewage is a discharge of waste as defined in Water Code section 13050(d) that could affect the quality of waters of the State and is subject to regulation by waste discharge requirements issued pursuant to Water Code section 13263 and Chapter 9, Division 3, Title 23 of the California Code of Regulations.
A discharge of sewage may pollute and alter the quality of the waters of the State to a degree that unreasonably affects the beneficial uses of the receiving water body or facilities that serve those beneficial uses (Water Code section 13050(l)(1)).
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
8 3.1.3 Water Boards Authority to Require Technical Reports, Monitoring, and Reporting Water Code sections 13267 and 13383 authorize the Regional Water Boards and the State Water Board to establish monitoring, inspection, entry, reporting, and recordkeeping requirements. Water Code section 13267(b), authorizes the Regional Water Boards to “require any person who has discharged, discharges, or is suspected of having discharged or discharging, or who proposes to discharge waste within its region… or is suspected of having discharged or discharging, or who proposes to discharge, waste outside of its region that could affect the quality of water within its region shall furnish, under penalty of perjury, technical or monitoring reports which the regional board requires…In requiring those reports, the regional board shall provide the person with a written explanation with regard to the need for the reports and shall identify the evidence that supports requiring that person to provide the reports.” Water Code section 13267(f) authorizes the State Water Board to require this information if it consults with the Regional Water Boards and determines that it will not duplicate the efforts of the Regional Water Boards. The State Water Board has consulted with the Regional Water Boards and made this determination.
The technical and monitoring reports required by this General Order and Attachment E (Notification, Monitoring, Reporting and Recordkeeping Requirements) are necessary to evaluate and ensure compliance with this General Order. The effort to develop required technical reports will vary depending on the system size and complexity and the needs of the specific technical report. The burden and cost of these reports are reasonable and consistent with the interest of the state in protecting water quality, which is the primary purpose of requiring the reports.
Water Code section 13383(a) authorizes the Water Boards to “establish monitoring, inspection, entry, reporting, and recordkeeping requirements… for any person who discharges, or proposes to discharge, to navigable waters, any person who introduces pollutants into a publicly owned treatment works, any person who owns or operates, or proposes to own or operate, a publicly owned treatment works or other treatment works treating domestic sewage, or any person who uses or disposes, or proposes to use or dispose, of sewage sludge.” Section 13383(b) continues, “the state board or the regional boards may require any person subject to this section to establish and maintain monitoring equipment or methods, including, where appropriate, biological monitoring methods, sample effluent as prescribed, and provide other information as may be reasonably required.”
Reporting of spills from privately owned sewer laterals and systems pursuant to section
5.15 (Voluntary Reporting of Spills from Privately-Owned Sewer Laterals and/or Private Sanitary Sewer Systems) of this General Order is authorized by Water Code section 13225(c) and encouraged by the State Water Board, wherein a local agency may investigate and report on any technical factors involved in water quality control provided the burden including costs of such reports bears a reasonable relationship to the need for the report and the benefits to be obtained therefrom. The burden of reporting private spills under section 5.15 (Voluntary Reporting of Spills from Privately-Owned Sewer Laterals and/or Private Sanitary Sewer Systems) is minimal and is outweighed by the benefit of providing Regional Water Boards an opportunity to respond to these spills
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
9 when an Enrollee, which in many cases has a contractual relationship with the owner of the private system, has knowledge of the spills.
3.1.4. Water Board Authority to Prescribe General Waste Discharge Requirements Water Code section 13263(i) provides that the State Water Board may prescribe general waste discharge requirements for a category of discharges if the State Water Board finds or determines that:
• The discharges are produced by the same or similar operations; • The discharges involve the same or similar types of waste; • The discharges require the same or similar treatment standards; and • The discharges are more appropriately regulated under general waste discharge requirements than individual waste discharge requirements.
Since 2006, the State Water Board has been regulating over 1,100 publicly owned sanitary sewer systems (See section 3.1.5 (Previous Statewide General Waste Discharge Requirements) of this General Order). California also has a large unknown number of unregulated privately owned sanitary sewer systems. All waste conveyed in publicly owned and privately owned sanitary sewer systems (as defined in this General Order) is comprised of untreated or partially treated domestic waste and/or industrial waste. Generally, sanitary sewer systems are designed and operated to convey waste by gravity or under pressure; system-specific design elements and system-specific operations do not change the common nature of the waste, the common threat to public health, or the common impacts on water quality. Spills of waste from a sanitary sewer system prior to reaching the ultimate downstream treatment facility are unauthorized and enforceable by the State Water Board and/or a Regional Water Board. Therefore, spills from sanitary sewer systems are more appropriately regulated under general waste discharge requirements.
As specified in Water Code sections 13263(a) and 13241, the implementation of requirements set forth in this Order is for the reasonable protection of past, present, and probable future beneficial uses of water and the prevention of nuisance. The requirements implement the water quality control plans (Basin Plans) for each Regional Water Board and take into account the environmental characteristics of sewer service areas and hydrographic units within the state. Additionally, the State Water Board has considered water quality conditions that could reasonably be achieved through the coordinated control of all factors that affect water quality, costs associated with compliance with these requirements, the need for developing housing within California, and the need to protect sources of drinking water and other water supplies.
3.1.5. Previous Statewide General Waste Discharge Requirements On May 2, 2006, the State Water Board adopted Order 2006-0003-DWQ serving as Waste Discharge Requirements pursuant to Article 4, Chapter 4, Division 7 of the Water Code (commencing with section 13260) for inadvertent discharges to waters of the State. Order 2006-0003-DWQ prohibited discharges of untreated or partially treated sewage. Order 2006-0003-DWQ also required system-specific management, operation, and maintenance of publicly owned sewer systems greater than one mile in length.
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
10 To decrease the impacts on human health and the environment caused by sewage spills, the previous Order required enrollees to develop a rehabilitation and replacement plan that identifies system deficiencies and prioritizes short-term and long-term rehabilitation actions. The previous Order also required enrollees to:
1. Maintain information that can be used to establish and prioritize appropriate Sewer System Management Plan activities; and
2. Implement a proactive approach to reduce spills.
The previous Order required Sewer System Management Plan elements for “the proper and efficient management, operation, and maintenance of sanitary sewer systems, while taking into consideration risk management.”
On July 30, 2013, the State Water Board amended General Order 2006-0003-DWQ with Order WQ 2013-0058-EXEC, Amending Monitoring and Reporting Program for Statewide General Waste Discharge Requirements for Sanitary Sewer Systems.
Many enrollees of Order 2006-0003-DWQ have already implemented proactive measures to reduce sewage spills. Other enrollees, however, still need technical assistance and funding to improve sanitary sewer system operation and maintenance for the reduction of sewage spills.
3.1.6. Existing Memorandum of Agreement with California Water Environment Association
The California Water Environment Association is a nonprofit organization dedicated to providing water industry certifications, training, and networking opportunities. The Association’s Technical Certification Program provides accredited sanitary sewer system operator certification for collection system operators and maintenance workers.
On February 10, 2016, the State Water Board entered into a collaborative agreement with the Association titled Memorandum of Agreement Between the California State Water Resources Control Board and the California Water Environment Association - Training Regarding Requirements Set Forth in Statewide General Waste Discharge Requirements for Sanitary Sewer Systems. The Memorandum sets forth collaborative training necessary for regulated sanitary sewer system personnel to operate and maintain a well operating system and ensure full compliance with statewide sewer system regulations.
On March 15, 2018, the State Water Board and the California Water Environment Association amended the existing Memorandum of Agreement to include collaborative outreach and expand training needs associated with further updates to Water Board regulations for sanitary sewer systems. The State Water Board encourages further Agreement updates as necessary to support improved sewer system operations and the professionalism of collection system operators.

11 3.2. General
3.2.1. Waters of the State
Waters of the State include any surface water or groundwater, including saline waters, within the boundaries of the state as defined in Water Code section 13050(e), and are inclusive of waters of the United States.
3.2.2. Sanitary Sewer System Spill Threats to Public Health and Beneficial Uses Sewage contains high levels of suspended solids, pathogenic organisms, toxic pollutants, nutrients, oxygen-demanding organic compounds, oil and grease and other pollutants. Sewage spills may cause a public nuisance, particularly when sewage is discharged to areas with high public exposure such as streets and surface waters used for drinking, irrigation, fishing, recreation, or other public consumption or contact uses.
More specifically, sanitary sewer spills may:
• Adversely affect aquatic life and/or threaten water quality when reaching receiving waters;
• Inadvertently release trash, including plastics;
• Impair the recreational use and aesthetic enjoyment of surface waters by polluting surface water or groundwater;
• Threaten public health through direct public exposure to bacteria, viruses, intestinal parasites, and other microorganisms that can cause serious illness such as gastroenteritis, hepatitis, cryptosporidiosis, and giardiasis; • Negatively impact ecological receptors and biota within surface waters; and • Cause nuisance including odors, closure of beaches and recreational areas, and property damage.
Sanitary sewer system spills may pollute receiving waters and threaten beneficial uses of surface water and groundwater. Potentially threatened beneficial uses include, but are not limited to the following (with associated acronym representations as included in statewide water quality control plans and Regional Water Boards’ Basin Plans):
• Municipal and Domestic Supply (MUN)
• Water Contact Recreation (REC-1) and Non-Contact Water Recreation (REC-2) • Cold Freshwater Habitat (COLD)
• Warm Freshwater Habitat (WARM)
• Native American Culture (CUL)
• Wildlife Habitat (WILD)
• Rare, Threatened, or Endangered Species (RARE)
• Spawning, Reproduction, and/or Early Development (SPWN) • Wetland Habitat (WET)
• Agricultural Supply (AGR)
• Estuarine Habitat (EST)

12 • Commercial and Sport Fishing (COMM)
• Subsistence Fishing (SUB)
• Tribal Tradition and Culture (CUL)
• Tribal Subsistence Fishing (T-SUB)
• Aquaculture (AQUA)
• Marine Habitat (MAR)
• Preservation of Biological Habitats of Special Significance (BIOL) • Migration of Aquatic Organisms (MIGR)
• Shellfish Harvesting (SHELL)
• Industrial Process Supply (PROC)
• Industrial Service Supply (IND)
• Hydropower Generation (POW)
• Navigation (NAV)
• Flood Peak Attenuation/Flood Water Storage (FLD)
• Water Quality Enhancement (WQE)
• Fresh Water Replenishment (FRSH)
• Groundwater Recharge (GWR)
• Inland Saline Water Habitat (SAL)
3.2.3. Proactive Sanitary Sewer System Management to Eliminate Spill Causes Finding 3 of the previous Order, 2006-0003-DWQ, states: “Sanitary sewer systems experience periodic failures resulting in discharges that may affect waters of the state.
There are many factors (including factors related to geology, design, construction methods and materials, age of the system, population growth, and system operation and maintenance), which affect the likelihood of an SSO [sanitary sewer overflow].
A proactive approach that requires Enrollees to ensure a system-wide operation, maintenance, and management plan is in place will reduce the number and frequency of SSOs within the state. This approach will in turn decrease the risk to human health and the environment caused by SSOs.”
Many spills are preventable through proactive attention on sanitary sewer system management using the best practices and technologies available to address major causes of spills, including but not limited to:
• Blockages from sources including but not limited to:
o Fats, oils and grease;
o Tree roots;
o Rags, wipes and other paper, cloth and plastic products; and o Sediment and debris.
• Sewer system damage and exceedance of sewer system hydraulic capacity from identified system-specific environmental, and climate-change impacts, including but not limited to:
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
13 o Sea level rise impacts including flooding, coastal erosion, seawater intrusion, tidal inundation and submerged lands;
o Increased surface water flows due to higher intensity rain events; o Flooding;
o Wildfires and wildfire induced impacts;
o Earthquake induced damage;
o Landslides; and
o Subsidence.
• Infrastructure deficiencies and failures, including but not limited to:
o Pump station mechanical failures;
o System age;
o Construction material failures;
o Manhole cover failures;
o Structural failures; and
o Lack of proper operation and maintenance.
• Insufficient system capacity (temporary or sustained), due to factors including but not limited to:
o Excessive and/or increased storm or groundwater inflow/infiltration; o Insufficient capacity due to population increase and/or new connections from industrial, commercial and other system users; and
o Stormwater capture projects utilizing a sanitary sewer system to convey stormwater to treatment facilities for reuse.
• Community impacts, including but not limited to:
o Power outages;
o Vandalism; and
o Contractor-caused or other third party-caused damages.
3.2.4. Underground Sanitary Sewer System Leakage
Portions of some sanitary sewer systems may leak, causing underground exfiltration (exiting) of sewage from the system. Exfiltrated sewage that remains in the underground infrastructure trench and/or the soil matrix, and that does not discharge into waters of the State (surface water or groundwater) may not threaten beneficial uses.
Underground exfiltrated sewage may threaten beneficial uses if discharged to waters of the State. Exfiltrated sewage that discharges to groundwater may impact beneficial uses of groundwater and pollute groundwater supply. Additionally, if in close proximity, exfiltrated sewage may enter into a compromised underground drainage conveyance system that discharges into a water of the United States, or into groundwater that is hydrologically connected to (feeds into) a water of the United States, thus potentially causing: (1) a Clean Water Act violation, (2) threat and impact to beneficial uses, and/or (3) surface water pollution.
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
14 3.2.5. Proactive Sanitary Sewer System Management to Reduce Inflow and Infiltration Excessive inflow (stormwater entering) and infiltration (groundwater seepage entering) to sanitary sewer systems is preventable through proactive sewer system management using the best practices and technologies available. The efficiency of the downstream wastewater treatment processes is dependent on the performance of the sanitary sewer system. When the structural integrity of a sanitary sewer system deteriorates, high volumes of inflow and infiltration can enter the sewer system. High levels of inflow and infiltration increase the hydraulic load on the downstream treatment plant, which can reduce treatment efficiency, lead to bypassing a portion of the treatment process, cause illegal discharge of partially treated effluent, or in extreme situations make biological treatment facilities inoperable (e.g., wash out the biological organisms that treat the waste).
3.3. Water Quality Control Plans, Policies and Resolutions The nine Regional Water Boards have adopted region-specific water quality control plans (commonly referred to as Basin Plans) that designate beneficial uses, establish water quality objectives, and contain implementation programs and policies to achieve those objectives. The State Water Board has adopted statewide water quality control plans, policies and resolutions establishing statewide water quality objectives, implementation programs and initiatives.
3.3.1. State Water Board Antidegradation Policy
On October 28, 1968, the State Water Board adopted Resolution 68-16, titled Statement of Policy with Respect to Maintaining High Quality of Waters in California, which incorporates the federal antidegradation policy. Resolution 68-16 requires that existing water quality be maintained unless degradation is justified based on specific findings.
The continued prohibition of sewage discharges from sanitary sewer systems into waters of the State aligns with Resolution 68-16. A sewage discharge from sanitary sewers to waters of the State is prohibited by this Order. Therefore, this Order does not allow degradation of waters of the State. In addition, this Order: (1) further expands the existing prohibition of sewage discharges to include waters of the State, in addition to waters of the United States as provided in previous Order 2006-0003-DWQ, and (2) enhances the ability for Water Board enforcement of violations of the established prohibitions.

On November 16, 2021, the State Water Board adopted Resolution 2021-0050 titled Condemning Racism, Xenophobia, Bigotry, and Racial Injustice, and Strengthening Commitment to Racial Equity, Diversity, Inclusion, Access, and Anti-racism. Among other actions, through Resolution 2021-0050, the State Water Board, in summary as corresponding to this General Order, reaffirms its commitment to its Human Right to Water resolution, upholding that every human being in California deserves safe, clean, affordable, and accessible water for human consumption, cooking, and sanitation purposes. Resolution 2021-0050 provides the State Water Board commitment to:
• Protect public health and beneficial uses of waterbodies in all communities, including communities disproportionately burdened by wastes discharge of waste to land and surface water;
• Restore impaired surface waterbodies and degraded aquifers; and • Promote multi-benefit water quality projects.
Through Resolution 2021-0050, the State Water Board also commits to expanding implementation of its Climate Change Resolution to address the disproportionate effects of extreme hydrologic conditions and sea-level rise on Black, Indigenous, and people of color communities, prioritizing:
• The right to safe, clean, affordable, and accessible drinking water and sanitation; • Sustainable management and protection of local groundwater resources; • Healthy watersheds; and
• Access to surface waterbodies that support subsistence fishing.
On June 7, 2022, the State Water Board adopted a Resolution, titled Authorizing the Executive Director or Designee to Enter into One or More Multi-Year Contracts Up to a Combined Sum of $4,000,000 for a Statewide Wastewater Needs Assessment, supporting the equitable access to sanitation for all Californians and implementation of Resolutions 2016-0010 and 2021-0050.

4.6 Spill Detection
Detection of a sanitary sewer spill may occur in numerous ways:
1. If an outside party calls in to report a spill, the Collection System Crew Supervisor in the Public Works/Street Maintenance Division or his/her designee shall be notified immediately. a. If this occurs after hours, the caller is directed to the Police Dispatch who will notify the on-call personnel.
2. The Collection System Crew Supervisor, or his/her designee, upon determining that the sewer problem is the City's responsibility, will mobilize necessary City personnel and equipment to the spill location and contact the City's active sewer maintenance/capital improvement program (CIP) services contractor for emergency service, if needed.
3. If there is a risk or threat to public safety, the Collection System Crew Supervisor will notify the Public Works Superintendent, or his/her designee, to oversee the response.
4. City personnel shall attempt to limit the spread of sewage by safe and appropriate means.
5. If the spill is contained within private property and is the responsibility of the private party. City personnel shall assist the responsible private property owner in contacting a qualified contractor to remove the waste material from their property.
6. City personnel involved in the Sewer Spill Response shall forward a report of the incident to their department head. The report shall detail the cause of the spill, actions taken to limit the spill, damage caused by the spill and action taken to remove the waste.
7. The City’s Legally Responsible Official (LRO), or his/her designee, shall report the spill event to the State and Regional Water Board and other agencies if applicable (such as County Health Officer, County Environmental Health Agency, Regional Water Board, and/or State Office of Emergency Services).
Section 4.2 of this Spill Emergency Response Plan details the chain of communication for reporting spills and contact numbers for these points of contact.
Pre-planned coordination and collaboration with the City’s stormwater staff will be implemented prior, during, and after a spill event.
4.7 Initial Spill Response
The Sanitary Sewer Overflow Response Procedure presents a strategy for the City of Pasadena to mobilize labor, materials, tools and equipment to correct or repair any condition which may cause or contribute to an un-permitted discharge. The plan considers a wide range of potential system failures that could create a sanitary sewer overflow (spill) to surface waters, land or buildings.
4.7.1 Receipt of Information Regarding a Spill
A spill may be detected by system employees or by others. During regular working hours Street Maintenance is primarily responsible for receiving phone calls from the public of possible spill from the wastewater collection system. After hours, the Poli ce Department Dispatch is the primarily responsible for contacting the necessary personnel to respond to a spill. The Police Dispatch (PD) number is staffed 24 hours a day every day of the year.
1. The telephone operator receiving the call should obtain all relevant information available regarding the overflow including:
City of Pasadena Spill Emergency Response Plan Page 10 a. Time and date call was received;
b. Specific location;
c. Description of problem;
d. Time possible overflow was noticed by the caller;
e. Caller’s name and phone number;
f. Observations of the spill (e.g., odor, duration, back or front of property); and g. Other relevant information that will enable the responding personnel to quickly locate, assess, contain and stop the overflow.
If the call is received during working hours the SMIWM division telephone operator then records the spill information and creates a work order for assignment to Collection System Crew Supervisor (CSCS). If the call is received after hours and dispatched by the PD, the responding stand-by personnel will document their actions to be recorded at the first available opportunity.
2. Pump station failures are monitored and received by the CSCS. Should there be a failure; the CSCS will immediately initiate the investigation and response action.
3. Spills detected by any personnel in the course of their normal duties shall be reported immediately to the SMIWM division. Dispatch personnel should record all relevant spill information and dispatch the CSCS or appropriate crew.
4. The CSCS shall confirm the spill. Until verified, the report of a possible spill will not be referred to as a “sanitary sewer overflow or a spill.”
5. Spill incidents will be tracked on the City of Pasadena’s daily sewer maintenance sheet and then downloaded to the Collection System Sections software tracking system
4.7.2 Dispatch of Appropriate Personnel to Site, Site Assessment and Coordination
Failure of any element within the wastewater collection system that threatens to cause or causes a spill will trigger an immediate response from the CSCS, who is on call for duty, to isolate and correct the problem. Personnel and equipment shall be available to respond to any spill location. Response personnel will be dispatched to any site of a reported spill immediately.
1. Dispatching Personnel
• Dispatchers should receive notification of sewer overflows as outlined above in Section 4.7.1 entitled “Receipt of Information Regarding a Spill” and dispatch the CSCS and/or the appropriate personnel and resources as required.
• Dispatchers shall notify the appropriate manager or supervisor by any means necessary regarding spills and field personnel locations.
2. Personnel Instructions and Work Orders
• Responding crews should be dispatched by the Call Center (311) , or any means necessary. Street
City of Pasadena Spill Emergency Response Plan Page 11 Maintenance should receive instructions from sewer investigators or their supervisors regarding appropriate personnel, materials, supplies, and equipment needed. • Dispatchers shall ensure that the entire message has been received and acknowledged by the personnel who are dispatched. All standard communications procedures should be followed. All personnel being dispatched shall proceed immediately to the site of the overflow. Any delays or conflicts in assignments must be immediately reported to the CSCS for resolution. • Response personnel should in all cases report their findings, including possible damage to private and public property, to the CSCS immediately upon making their investigation. If the CSCS has not received findings from the field personnel within 30 minutes of being dispatched, the CSCS shall contact the response personnel to determine the status of the investigation. • CSCS shall refer all pertinent information to the Public Works Superintendent, including any details of the problems described by customers.
3. Additional Resources
• CSCS should receive and shall convey to appropriate parties’ requests for additional personnel, material, supplies, and equipment from crews working at the site of a spill.
4. Site Assessment
City staff shall investigate and assess the site conditions where the spill occurred using the following methods:
• Determine the Category of the spill. (Refer to Section 4.9, “Spill Categories,” for more information.) • Determine the size and extent of the spill.
• Determine any potential hazards, such as vehicle and pedestrian traffic. • Identify receiving water that may be impacted by spill. • Document and recording all pertinent information of the spill. • Implement traffic control measures as needed per the WATCH Manual. Should you need traffic or crowd control assistance, call Police dispatch at (626) 744-4501 to assist with street closure, traffic diversion, or crowd control.
• Post warning signs and block contaminated areas with yellow caution tape and/or barricades if spill poses a public threat or it has or will reach waters of the State. • If spill overflow location calls for it, the CSCS will contact the Public Works Superintendent to arrange for a partial activation of the Emergency Operations Center (EOC).
5. Preliminary Assessment of Damage to Private and Public Property • The response personnel shall not enter private property for purposes of assessing damage. It is the primary responsibility of the response personnel to contain sewage and attempt to clear any blockage in the collection system.
City of Pasadena Spill Emergency Response Plan Page 12 • Given consent by the private property owners, the Public Works Superintendent is responsible for entering private property taking the appropriate still photographs and/or video footage. If possible, pictures should be taken of all indoor and outdoor areas the spill has impacted. • Thoroughly document the nature and extent of impacts. • Available photographs are to be forwarded to Public Works Superintendent for documentation proposes.
6. Field Supervision and Inspection
• The Public Works Superintendent, who is on call, should visit the site of the spill to ensure that provisions of this SERP and other directives are met.
• The Public Works Superintendent is responsible for confirming that the spill is documented correctly, and that information conveyed to the SMIWM Division Administrator.
7. Coordination with Hazardous Material Response
• Upon arrival at the scene of a sewer spill, should a suspicious substance (e.g., oil sheen, foamy residue) be found on the ground surface, or should a suspicious odor (e.g., gasoline) not common to the sewer system be detected, the CSCS or the response personnel should immediately contact their supervisor for guidance before taking further action.
• Should the supervisor determine the need to alert the hazardous material response team, the CSCS and/or personnel on the scene shall await the arrival of the City of Pasadena’s Hazardous Materials Personnel (COPHMP) to take over the scene.
• Remember that any vehicle engine, portable pump or open flame (e.g., cigarette lighter) can provide the ignition for an explosion or fire should flammable fluids or vapors be present. Keep a safe distance and observe cautiously until assistance arrives.
• Upon arrival of the COPHMP, the CSCS and/or Collection System Personnel will take direction from the person with the lead authority of that team. Only when that authority determines it is safe and appropriate for the CSCS and/or Collection System Personnel to proceed under the SERP with the containment, clean-up activities and correction.
4.8 Spill Correction and Containment
Spills of various volumes occur from time to time in spite of concerted prevention efforts. Spills may result from blocked sewers, pipe failures, or mechanical malfunctions among other natural or man -made causes. City of Pasadena is constantly on alert and should be ready to respond upon notification and confirmation of a spill.
This section describes specific actions to be performed by the crews during a spill. The objectives of these actions are:
• To protect public health, environment and property from sewage spills and restore surrounding area back to normal as soon as possible;
• To establish perimeters and control zones with appropriate traffic cones and barricades, vehicles or use
City of Pasadena Spill Emergency Response Plan Page 13 of natural topography (e.g., hills, berms);
• To promptly notify the regulatory agency’s communication center of preliminary spill information and potential impacts;
• To contain the sewer spill to the maximum extent possible including preventing the discharge of sewage into surface waters; and
• To minimize the City of Pasadena’s exposure to any regulatory agency penalties and fines.
Under most circumstances, the City of Pasadena will handle all response actions with its own maintenance forces. They have the skills and experience to respond rapidly and in the most appropriate manner. An important issue with respect to an emergency response is to ensure that the temporary actions necessary to divert flows and mitigate or control the problem. For example, repair of a force main could require the temporary shutdown and diversion of the flow at an upstream location. If the closure is not handled properly, sewage system back-ups may create other SSO.
4.8.1 Responsibilities of Response Crew upon Arrival
It is the responsibility of the first personnel who arrive at the site of a sewer spill to protect the health and safety of the public by mitigating the impact of the overflow to the extent possible. Should the spill not be the responsibility of City of Pasadena but there is imminent danger to public health, public or private property, or to the quality of waters of the State, then prudent emergency action should be taken until the responsible party assumes responsibility and provides actions.
It should be noted that in case of emergency when public health, safety and welfare is jeopardized as declared by the Health Department, the following parties are empowered as Peace Officers to enter into private properties for immediate spill response: Police Officers, Fire Fighters, City Engineer and/or Public Works Director, and Health Officials.
Upon arrival at a spill, the response crew should do the following:
• Determine the cause of the spill, e.g. sewer line blockage, pump station mechanical or electrical failure, sewer line break, etc.;
• Once cause is determined, ownership of the problem needs to be identified. • Identify and request, if necessary, assistance or additional resources to correct and/or contain spill or to assist in the determination of its cause;
• Determine if private property is impacted. If yes, the dispatcher should be informed so that the Pasadena Health Department may be advised.
• Upon determination of private property being damage as a result of City of Pasadena collection system generated spill, the CSCS will contact a water damage clean-up contactor to execute emergency clean up at City expense.
• Take immediate steps to stop the spill, e.g. relieve pipeline blockage, manually operate pump station controls, repair pipe, etc. Extraordinary steps may be considered where spills from private property threaten public health and safety (e.g., a spill running off of private property into the public right-of-way); • If the cause is determined to be private generated spill, and the damage is limited to the property, upon request the CSCS may provide a list of contactors to assist with clean up and/or pipe clearance. • If necessary, request additional personnel, materials, supplies, or equipment from Departments of Police, Fire and Health that will expedite and minimize the impact of the overflow, such as traffic diversion, crowd control, and street closure.
City of Pasadena Spill Emergency Response Plan Page 14
4.8.2 Containment Procedures
Containment of the spill is the top priority. City staff respond initially to spill calls and perform spill to correct blockages, perform spill recovery and any necessary emergency repairs. If the City crews require additional support, they may contact the City’s active pipeline CIP contractor for emergency support. The City’s active CIP contractor varies per fiscal year. The City’s current emergency pipeline contractor and contact information are listed in this section by the City and are noted below:
Active CIP Contractor Southwest Pipeline and Trenchless Corp (310) 329-8717
The City’s crew will attempt to keep the spill in as small an area as possible. If reasonable, the crew should attempt to keep the spill in the street and out of the storm drain or other surface water bodies. To ensure the spill is contained, the crew will use the following methods:
1. Contain the spill immediately. Contain sewage on the ground using a manmade berm if applicable.
2. Isolate, contain, and/or divert sewage flow from any open channels and storm drain structures using sandbags, inflatable dams, or soil barriers. Sandbags or absorbent material can be used around the spill to collect the sewage and prevent it from spreading.
3. Block the storm drain openings or divert flow with sandbags and plastic sheets, which are available at several locations around the City. If reasonable, keep the flow contained on the street. Pay special attention to blocking storm drain inlets of any kind, both downstream and upstream of the spill. Setup traffic control per the WATCH Manual. Should you need traffic or crowd control assistance, call police dispatch at (626) 744-4501.
4. Should the spill take place in an area not normally accessible to the public (i.e. field, etc.) the crew will use any reasonable means to pool the flow in that area for recovery.
5. Capture the spill.
a. If necessary, berm flow and start pumping into the closest clear and flowing manhole. b. Contact the Public Works Superintendent at (626) 744-4808. c. Evaluate the sewer system spill rate. The most senior employee on scene will evaluate the spill rate.
6. Determine the source and/or cause of the spill (i.e., evaluate type and amount of debris, illegal activities, etc.). City staff may need to observe downstream manholes to establish the location of the cause of the spill such as a blockage.
a. If the cause is determined to be privately generated, and the damage is limited to the property, upon request the CSCS may provide a list of contactors to assist with clean up and/or pipe clearance.
7. Clear the obstruction and restore flow.
a. Restore system flow by hydro jetting, rodding, open cut excavating, or any other means to clear the blockage or failure point.
b. If necessary, City Staff should set up a hydro jetter downstream of the blockage and jet upstream from a clear manhole.
c. Capture as much of the material causing the blockage as possible. d. If unable to relieve the blockage, request immediate assistance from additional staff and appropriate equipment.
e. If still unable to clear the blockage, request immediate assistance with the establishment of bypass pumping and CCTV support to determine the problem. f. If engineering consultation is necessary, contact the Public Works Superintendent (or Public
City of Pasadena Spill Emergency Response Plan Page 15 Works Director if he/she cannot be reached). He/she shall initiate an emergency work order to the City’s on-call contractor to repair the pipe.
g. Ensure the downstream manholes are clear and flowing.
8. Should the flow be too much to be contained in the street and is identified as a danger to the public the crew will allow the flow to enter the storm drain or catch basin. The crew will plug upstream and downstream portions of impacted storm drains or catch basins and recover it from that point using a vacuum truck and/or set up a diversion to a downstream manhole.
9. If necessary, request additional personnel, materials, supplies, or equipment from Departments of Police, Fire and Health that will expedite and minimize the impact of the spill, such as traffic diversion, crowd control, and street closure.
10. Upon determining and correcting the source and/or cause of the spill, a sample of the sewage may be taken as evidence for possible analysis.
11. All sewage shall be captured and discharged into the closest clear and flowing manhole. Any contaminated materials unfit for the sewer and likely to cause blockages shall be transported to a local landfill for ultimate disposal. See Section 4.9 for treatment in dry or wet weather conditions and collection instructions.
12. Estimate volume of the spill as detailed in Section 4.16.2.
13. Notify regulatory agencies about the spill and follow any additional instructions they may have.
4.8.3 Sewer Bypassing
If the spill involves damage to or collapse of a pipeline, or the spill has been determined to be prolonged for any reason, and a by-pass is necessary:
1. By-pass action is to be administered, as soon as conditions safely allow, by City personnel at the location where the damaged pipeline occurs.
2. Place appropriate pumps and hoses to keep sewage in the sewerline. Appropriate measures shall be taken to determine the proper size and number of pumps required to effectively handle the sewage flow.
The City is considering keeping a list of contacts for equipment rental companies or contractors in case additional pumps, piping, or hoses are required to conduct a bypass. If this list is created, it will be in the change log.
3. Continuous or periodic monitoring of the by-pass pumping operation shall be implemented as required.
4. Perform repairs to the damaged sewerline as soon as conditions safely allow and as resources are available.
5. Regulatory agency issues shall be addressed in conjunction with emergency repairs.
6. If engineering consultation is necessary, the City has a list of On-Call Engineering Firms. The following includes a current list of the City’s On-Call General Civil Engineering Firms:
On-Call Engineering Firm(s) Phone
Dudek (760) 942-5147
4.9 Recovery and Clean-Up (Mitigation)
1. If the spill occurs during dry weather conditions:
City of Pasadena Spill Emergency Response Plan Page 16 a. If necessary, Police Officers should be dispatched to assist street closure, traffic diversion, or crowd control.
b. The spill site is to be secured to prevent contact by members of the public until the site has been thoroughly cleaned.
c. Once the spill has been eliminated, use rakes, brooms, and other applicable tools to scrape up and remove all solids and debris and transported for proper disposal. d. Any remaining standing sewage shall be vacuum pumped and discharged into the closest manhole (ensure it is clear and flowing).
e. Any contaminated soil shall have free standing sewage or water vacuumed up, lime applied, allowed to dry, and then removed (as necessary) by means of heavy equipment and transported to a local landfill for ultimate disposal.
f. Any contaminated structures such as streets, sidewalks, buildings, etc., shall be disinfected by pressure spraying with a 25 ppm sodium hypochlorite (liquid bleach) solution. After providing a contact time of 1 hour, the disinfected structures shall be rinsed with city water, and the wash water vacuumed and disposed of into the closest manhole (ensure it is clear and flowing). i. BEFORE PRESSURE WASHING CONTAMINATED AREA, ALL CONTAMINATED MATERIALS AND CONTAMINATED SOIL MUST BE REMOVED AND CATCH BASINS MUST BE BLOCKED.
VACUUM MUST BE READY TO PICK UP WATER FROM PRESSURE WASHING. No water, sewage, bleach, or containment materials are to be washed into the storm drain system. ii. If the spill occurred in a heavily populated area or is within 100 feet of surface water, bleach should not be used.
g. If wastewater enters the storm drain or catch basin, a vactor truck may be used to vacuum the sump at a downstream catch basin, while clean water is used to flush the curb, gutter, and pipe upstream.
h. Leave the area as clean as possible picking up rags, papers, etc. Emphasis should be placed on removing all materials that are on or around the contaminated area. i. Restore the area to its original condition, or as close as possible. j. Documentation and recording of all pertinent information of the spill shall be completed prior to leaving the site.
2. If the spill occurs during wet weather conditions:
a. If necessary, Police Officers should be dispatched to assist street closure, traffic diversion, or crowd control.
b. The spill site is to be secured to prevent contact by members of the public until the site has been thoroughly cleaned.
c. Once the spill has been eliminated, use rakes, brooms, and other applicable tools to scrape up and remove all solids and debris and transported for proper disposal. d. Any remaining standing sewage shall be vacuum pumped and discharged into the closest clear and flowing manhole.
e. Any contaminated soil shall have free standing sewage or water vacuumed up, lime applied, allowed to either dry or sit for an hour, and then removed (as necessary) by means of heavy equipment and transported to a local landfill for ultimate disposal. i. Omit lime application during heavy storm events with heavy runoff, where the surface water cannot be contained.
f. Any contaminated structures such as streets, sidewalks, buildings, etc., shall be cleaned with clean water. Avoid using bleach during wet weather as the bleach can harm the environment. g. If wastewater enters the storm drain or catch basin, a vactor truck may be used to vacuum the sump at a downstream catch basin, while clean water is used to flush the curb, gutter, and pipe
City of Pasadena Spill Emergency Response Plan Page 17 upstream.
h. Leave the area as clean as possible picking up rags, papers, etc. Emphasis should be placed on removing all materials that are on or around the contaminated area. i. Restore the area to its original condition, or as close as possible. j. Documentation and recording of all pertinent information of the spill shall be completed prior to leaving the site.
i. If a spill is caused by lack of capacity during wet weather conditions, document the storm event and forward information to the Public Works Manager.
4.10 Spill Categories
Per the Reissued WDR, there are now four (4) categories of spills. Individual spill notification, monitoring and reporting must be in accordance with the following spill categories:
4.10.1 Category 1 Spill
A Category 1 spill is a spill of any volume of sewage from or caused by a sanitary sewer system regulated under this General Order that results in a discharge to:
• A surface water, including a surface water body that contains no flow or volume of water; or • A drainage conveyance system that discharges to surface waters when the sewage is not fully captured and returned to the sanitary sewer system or disposed of properly.
Note: Any spill volume not recovered from a drainage conveyance system is considered a discharge to surface water, unless the drainage conveyance system discharges to a dedicated stormwater infiltration basin or facility.
A spill from a City-owned and/or operated lateral that discharges to a surface water is a Category 1 spill; the City will report all Category 1 spills per Appendix B, Section B-1 of this document.
4.10.2 Category 2 Spill
A Category 2 spill is a spill of 1,000 gallons or greater, from or caused by a sanitary sewer system regulated under this General Order that does not discharge to a surface water.
A spill of 1,000 gallons or greater that spills out of a lateral and is caused by a failure or blockage in the sanitary sewer system, is a Category 2 spill.
4.10.3 Category 3 Spill
A Category 3 spill is a spill of equal to or greater than 50 gallons and less than 1,000 gallons, from or caused by a sanitary sewer system regulated under this General Order that does not discharge to a surface water.
A spill of equal to or greater than 50 gallons and less than 1,000 gallons, that spills out of a lateral and is caused by a failure or blockage in the sanitary sewer system is a Category 3 spill.
City of Pasadena Spill Emergency Response Plan Page 18
4.10.4 Category 4 Spill
A Category 4 spill is a spill of less than 50 gallons, from or caused by a sanitary sewer system regulated under this General Order that does not discharge to a surface water.
A spill of less than 50 gallons that spills out of a lateral and is caused by a failure or blockage in the sanitary sewer system is a Category 4 spill.
4.11 Spill Reporting and Tracking
Spill documentation shall be completed by the CSCS and reviewed by the Public Works Superintendent. Public Works Supervisor shall promptly notify the Street Maintenance (SM) Division Administrator when the overflow is eliminated. Information regarding the spill should include the following:
1. Indication that the spill had reached surface waters, i.e., all spills where sewage was observed running to surface waters or a drainage system where the flows were not fully captured, or there was obvious indication (e.g. sewage residue) that sewage flowed to surface waters; and
2. Indication that the spill had not reached surface waters. Guidance in characterizing these spills to include:
a. Sewage spills to covered storm drains (with no public access) where personnel verify, by inspection, that the entire volume is contained in a sump or impoundment and where complete clean-up occurs leaving no residue.
b. Preplanned or emergency maintenance jobs involving bypass pumping if access by the public to a bypass channel is restricted and subsequent complete clean -up occurs leaving no residue (Any preplanned bypass under these circumstances will not be considered spill); and c. Spills where observation or on-site evidence clearly indicates all sewage was retained on land and did not reach a surface water and where complete cleanup occurs leaving no residue.
3. Determination of the start time of the spill by one of the following methods:
a. Date and time information received and/or reported to have begun and later substantiated by the CSCS or response crew;
b. Visual observation.
4. Determination of the stop time of the spill by one of the following methods:
a. When the blockage is cleared or flow is controlled or contained; or b. The arrival time of the CSCS or response crew, if the spill stopped between the time it was reported and the time of arrival.
5. Visual observations, such as:
a. An estimation of the rate of spill in gallons per minute (GPM) by one of the following criteria:
i. Direct observations of the overflow; or
City of Pasadena Spill Emergency Response Plan Page 19 ii. Measurement of actual overflow from the sewer main.
6. Determination of the volume of the sewer overflow:
a. When the rate of spill is known, multiply the duration of the spill by the spill rate; or b. When the rate of spill is not known, investigate the surrounding area for evidence of ponding or other indications of spill volume; and
c. Refer to Section 4.16.2 for Spill Volume Estimation.
7. Photographs of the event, when possible.
8. Assessment of any damage to the exterior areas of public/private property. CSCS shall enter private property for purposes of estimating damage to structures, floor and wall coverings, and personal property.

4.16 Spill-Specific Monitoring Requirements
4.16.1 Spill Location and Spread
The City shall visually assess the spill location(s) and spread using photography, global positioning system (GPS), and other best available tools. The City shall document the critical spill locations, including:
• Photography and GPS coordinates for:
o The system location where spill originated.
o For multiple appearance points of a single spill event, the points closest to the spill origin. • Photography for:
o Drainage conveyance system entry locations,
o The location(s) of discharge into surface waters, as applicable, o Extent of spill spread, and
o The location(s) of clean up.
4.16.2 Spill Volume Estimation
To assess the approximate spill magnitude and spread, the City shall estimate the total spill volume using updated volume estimation techniques, calculations, and documentation for electronic reporting. The City utilizes direct measurement based on container volume as well as dipstick measurements. The estimated spill volume is calculated by the rate at which the manhole fills during the spill, using the volume inside the manhole. The City shall update its notification and reporting of estimated spill volume (which includes spill volume recovered) as further information is gathered during and after a spill event.
4.17 Public Access and Warning

1 Introduction
The Sanitary Sewer System Spill water Quality Monitoring Plan (Monitoring Plan) provides technical information for water quality monitoring locations and techniques that may be used to characterize the relative impacts to the receiving water quality in the event of a sanitary sewer spill (spill) within the City of Pasadena (City) service area. In the event of a spill, it is assumed response actions identified in the City’s Spill Emergency Response Plan and Sewer System Management Plan (SSMP) will be implemented to protect public health and the environment. This plan covers details on monitoring receiving water quality separate from the emergency response and cleanup efforts.
Recent updates to the waste discharge requirements general order for sanitary sewer systems 1 (WDR) require timely implementation of spill-specific notification, monitoring, and reporting tasks for spill events that exceed certain volume thresholds. In the event of a spill >50,000 gallons, the WDR outlines monitoring requirements generally aligned to estimate spill location and spread as well as receiving water conditions to support impact analysis documented in a spill report. This Monitoring Plan provides technical and procedural details to allow for rapid implementation of water quality monitoring activities that may be used to characterize the extent and magnitude of potential impacts related to a spill. These water quality activities are based on standard procedures implemented as part of municipal and industrial water quality monitoring programs.
Surface runoff in the geographical area served by City flows into both City of Pasadena storm drains and Los Angeles County Flood Control District (LACFCD) storm drains. Receiving water quality monitoring has been conducted in these drains as part of various compliance, special study , and third-party efforts over the past two decades. The suite of previously monitored locations provides a resource for efficient identification of logistically feasible locations for City spill response monitoring. Wet and/or dry weather water quality samples have been collected at these monitored locations. These data may be comparable to samples collected as part of a spill response or for other purposes.
The City operates and maintains a wide array of sanitary sewer piping, manholes, pump stations, force mains, and other associated infrastructure. The location of major collection system assets and components, watershed configuration, drainage characteristics, safety, and accessibility were used to select a distributed array of water quality monitoring locations that may be used during a spill response event. In the event of a spill , it is recommended that City staff evaluate the spill size, location, duration, volume, and ambient weather conditions to develop a focused water quality monitoring strategy and monitoring plan.
The overall purpose of this document is to provide the following information:
• A geographic overview of City assets
• Representative water quality monitoring locations that may be used for a spill response or guide identification of alternative locations in the future
• Site description and access information for the representative water quality monitoring locations

15275.05 2 MAY 2025
• A summary of water quality monitoring methods and protocols The following sections provide background information and sample collection methodology for the proposed monitoring locations. Detailed site descriptions for each proposed monitoring location are provided in Section 6. 2 Background
Wastewater and stormwater 2 discharges from the City are regulated through state issued permits that define management, monitoring, and reporting requirements. These WDRs are created based on evaluation of the City’s threat to water quality and quality of the receiving waters.
The City operates under the Coastal Watersheds of Los Angeles County Phase I municipal separate storm sewer system (MS4) permit (MS4 Permit) and is part of the Upper Los Angeles River Watershed Management Area Group.
Under the MS4 Permit, the City monitors storm drain outfalls during wet- and dry-weather to detect non-storm water discharges to its MS4 and monitoring water quality during storm events as part of the Coordinated Integrated Monitoring Program (CIMP). Non-stormwater discharges may come from many sources including, but not limited to, illicit connections, illicit discharges, and sewage spills. This document pertains to water quality as a result of a sewage spill, however, monitoring results from the regional CIMP are useful for comparison with spill event samples.
2.1 Spill Monitoring Plan Framework
The WDR Attachment E1 (Appendix A) includes spill notification, spill location and spread observations, monitoring, and reporting requirements. Implementation requirements for these elements are summarized below.
Notification
For any spill that discharges in or on any waters of the State, the discharger is to notify the California Office of Emergency Services (Cal OES) as soon as possible but no later than two (2) hours after: a) knowledge of the spill; and b) notification can be provided without interfering with cleanup/emergency measures.
Cal OES Warning Center: (800) 852-7550
Location and Spread Observations
In the event of a spill, the discharger visually assess es the spill locations and extent using photography, global positioning system (GPS) and other tools such as a measuring devices to quantify the spill area/length and depth.
Key documentation includes:
• The system location where spill originated
o For multiple appearance points of a single spill event, the points closest to the spill origin.
2 National Pollutant Discharge Elimination System (NPDES) Waste Discharge Requirements (WDRs) for Municipal Separate Storm Sewer System (MS4) Discharges within the Coastal Watersheds of Los Angeles County, Except those Discharges originating from the City of Long Beach MS4 Order R4-2012-0175-A01 NPDES NO. CAS004001
SANITARY SEWER SPILL MONITORING PLAN
15275.05 3 MAY 2025
• Drainage conveyance system spill entry locations
• Locations where spill discharges to receiving water
• Extent of spread and locations of cleanup
Additionally, the discharger needs to estimate the spill volume using appropriate techniques, calculations, and documentation for electronic reporting.
Following spill volume estimation, the discharger is required to perform visual observations for spills that discharge to receiving waters. Key documentation includes:
• Estimated spill travel time to receiving water
o For spills entering a drainage conveyance system, this includes travel time from entry into the drainage conveyance system to receiving water discharge • Spill volume entering receiving water
• Photography:
o Waterbody bank erosion (if applicable)
o Floating matter
o Surface sheen (oil and grease)
o Discoloration of receiving waters
Monitoring
A spill estimated at 50,000 gallons or greater discharged to receiving water requires the discharger to perform water quality monitoring. Monitoring must be conducted no later than 18-hours after the discharger’s knowledge of a potential discharge to a surface water.
Daily s amples must be collected at the discharge point to the receiving water and at location s upstream and downstream of the discharge point. If the spill entered the receiving water from a drainage conveyance, a sample must be taken from within the conveyance as well, given spill material is still present. Upstream samples should be taken at a sufficient distance from the discharge point to capture ambient conditions absent of spill material. The upstream sample point is ideally collected where the receiving water enters the City boundary, at a point where the water quality is unaffected by discharges from the City. Downstream sample point must be taken far enough from the discharge point where the spill material is fully mixed with the receiving water. The downstream sample point should be evaluated for conditions in the receiving water at the time spill such as flow rate and velocity. If a spill occurs during a large rain event, then mixing will occur more quickly (and less distance downstream from the spill) than during dry weather or low flow conditions. The furthest downstream point before the receiving water leaves the City boundary will yield the best mixing condition.

15275.05 4 MAY 2025
Once collected, the samples must be submitted to a certified laboratory in a timely manner for analysis of ammonia and fecal indicator bacteria.
Reporting
Electronic reporting to the California Integrated Water Quality System (CIWQS)3 is required for all spills. For spills greater than 50,000 gallons and discharged to receiving waters, a Spill Technical Report is required within 45 days of the spill end date. The Spill Technical Report must contain the following:
• Spill causes and circumstances
• Discharger’s response to spill
• Water quality monitoring information
• Evaluation of spill impacts, including short- and long-term impact(s) to beneficial uses of surface waters Spill report information is then used by Regional Water Quality Control Board staff to evaluate the relative impact to the environment and to form the basis of potential spill-specific enforcement actions.
2.2 Geographic Setting
The City’s sewer service area includes 23.1 square miles. Major water bodies within the City include three primary runoff drainages with seasonal and permanent water impoundments (Figure 1).
The City drains to the south and ranges in elevation from approximately 1,800 feet above mean sea level (AMSL) to 466 feet AMSL5. The major drainage areas within the City include Arroyo Seco, Alhambra Wash, Rubio Wash, and Eaton Wash. Generally, these drainage areas flow north to south. Arroyo Seco and Eaton Wash have surface water channels within the City whereas the portions of the City that are in Alhambra and Rubio Wash do not.

2.3 Pasadena Assets
The City operates and maintains a sanitary sewer collection system that provides service to approximately 133,560 residents4. The City operates and maintains approximately 328 miles of gravity pipelines and 41 miles of force mains, which serve the majority of the City’s 23.1 square mile City limits and conveys an annual average flow of approximately 14 million gallons per day 5. The City’s sanitary collection system conveys these untreated flows to the Los Angeles County Sanitation District’s (LACSD) trunk sewer system. A summary of the City’s pump stations and force mains are presented below in Figure 2. In general, these assets constitute infrastructure that have potential to contribute to spills that may require a monitoring program and were used in the sample location assessment presented in Section 3.
2.4 Potential Monitoring Locations
Within the context of the City’s geography and sewer system assets, a suite of p otential spill monitoring locations were identified for this Monitoring Plan. The monitoring locations were selected to provide core representation of locations where critical sewer infrastructure has potential for a large spill event, adjacent stormwater conveyance and other infrastructure has potential to be impacted by a large spill event, and during/post-event monitoring at the selected locations may provide reasonable capacity to characterize impacts to water quality from a spill. While specific monitoring locations have been identified, the City may at any time change these locations because of access constraints and/or changes in operations.
A spill that impacts water quality is likely to be conveyed through the MS4 before reaching the receiving water, however, in limited situations a spill immediately adjacent to a receiving water may discharge directly to the water body. The WDR defines four distinct monitoring location types (Figure 3):
• Flow in MS4 or non-sewer infrastructure conveyance(s) prior to the discharge point • Receiving Surface Water (RSW) discharge point
• RSW upstream of the discharge point
• RSW downstream of the discharge point
The location of a spill event will determine t he exact monitoring location (s) needed to be sampled based on discharge point to the receiving water . However, the core monitoring locations and methods documented in this Monitoring Plan allow for rapid identification and implementation of a monitoring program that will both meet the requirements of the WDR and provide critical information that may be used to inform the required Spill Technical Report impact analysis. Accordingly, this Monitoring Plan only identifies potential upstream and downstream monitoring locations. Monitoring in the MS4 or non -sewer infrastructure conveyance(s) as well as RSW discharge point monitoring locations will be assessed by the City on a spill-by-spill basis.

2.5 Water Quality Sample Constituents
Attachment E of the WDRs list two required constituents to monitor in surface water impacted by a sewer spill. All water quality samples are required to measure the concentration of ammonia and the concentration of the appropriate bacterial indicator(s) per the applicable Basin Plan water quality objectives. For Pasadena, the Los Angeles Regional Board's Basin Plan6 identifies E-coli and Enterococcus as the fecal indicator bacteria for the region. Table 1 identifies the required constituents to sample for and information on the specific requirements for each sample method.

3 Monitoring Site Selection
A desktop analysis was conducted using the location of known City assets, watershed boundaries, and the City boundary in geographic information system (GIS). The analysis resulted in a suite of potential monitoring locations that were prioritized based on the following characteristics:
• Proximity to City sewer assets
• Ability for a spill to flow to a receiving water
• Potential for monitoring site to serve as a reference point for the City The monitoring sites included in this Monitoring Plan were chosen based on their ability to characterize water quality conditions before and after being influenced by a spill. Due to the transient nature of a spill, only specific upstream and downstream monitoring locations are identified at this time.
3.1 Downstream Monitoring Sites
Downstream monitoring locations are defined in the WDR as being “a point in the receiving water, downstream of the point of sewage discharge, where the spill is fully mixed with the receiving water.” Receiving waters in the City are defined by four separate watersheds: Arroyo Seco, Alhambra Wash, Rubio Wash, and Eaton Wash. For Arroyo Seco, only a single downstream point is necessary to monitor a spill since this watershed has a single above ground channel leaving the City boundary. This point represents where a spill that discharged into Arroyo Seco upstream either from a storm drain outfall or direct surface runoff is fully mixed with the receiving water.
Alhambra and Rubio Wash do not have surface level receiving waters within the City boundary. Runoff in Alhambra and Rubio Wash leaves the City boundary through 11 underground discharge points that connect into the adjacent jurisdictions’ storm drains. Since the City does not have control over the water quality in the storm drain once it leaves the City , downstream drainage conveyance monitoring sites have been established for these 11 underground discharge points at the closest manhole before runoff leaves city limits. These specific locations act as the most downstream points in Alhambra and Rubio Wash to monitor water quality in the event of a sewer spill upstream within the washes.
Eaton Wash has both a downstream receiving water monitoring location as well as multiple drainage conveyance monitoring locations. Due to the geography and jurisdictional boundaries along the southeastern edge of the City, There are portions of Eaton Wash that receive runoff (or a spill) from the City but the open channel of the wash itself is outside the City boundary. Therefore, a receiving water monitoring location was placed at the most downstream point of the open channel portion of Eaton Wash before l eaving the City, and downstream drainage conveyance monitoring locations were placed on the storm drains that leave the City south of the surface water monitoring point.
SANITARY SEWER SPILL MONITORING PLAN
15275.05 12 MAY 2025
3.2 Upstream Monitoring Sites
The WDR defines an upstream monitoring site as being “a point in the receiving w ater, upstream of the point of sewer discharge, to capture ambient conditions absent of sewage discharge impacts.” For the Monitoring Plan, upstream monitoring locations were selected for each of the major drain age areas upstream of City sewer assets and storm drain outfalls. Upstream monitoring locations were also selected based on proximity to major roads and ease of access to the receiving water. Upstream monitoring locations presented in this Monitoring Plan are intended to be used for any spill that occurs downstream in the specified drainage area. Specific monitoring locations have been identified in Arroyo Seco, Rubio Wash, and Eaton Wash. Since the Alhambra Wash originates within the City, the upstream monitoring location will be assessed by the City on a case by case basis as there may not be an upstream flow in the storm drain depending on the timing of the spill.
A suite of core monitoring locations derived from this assessment are presented below in Figure 4. More detailed site-specific fact sheets for these locations area presented in Section 6. In the event of a spill, it is recommended that City staff evaluate the spill location with respect to the sample locations presented in Figure 4 to determine an appropriate upstream and downstream monitoring location. Selection of drainage conveyance and discharge point monitoring location should be identified by visually inspecting the spill pattern on the ground surface and identifying if any material has flowed into the MS4 and/or directly discharged into a surface water.

4 Monitoring Procedures Overview
In general, the core monitoring locations are located in open stormwater channels and use methodology derived from industry standard water quality sample collection procedures. Standard methods include documenting site conditions and sample characteristics (color, odor, turbidity, etc.) , flow estimations, and other observations and activities that may be used to evaluate water quality or sample collection specifics.
Water quality monitoring requires the coordination of both field personnel and the selected analytical laboratory during monitoring events, as well as proper management of field and laboratory data. Monitoring event preparation includes allocating sample collection equipment, bottles, labels, and chain of custodies (CoCs). Activities to be performed during a monitoring event include the proper collection and handling of water samples and the submission of samples within laboratory holding times. In addition to the field effort involved with monitoring, such as travel, parking, sample collection and handling, additional effort is required after a monitoring event to ensure the proper management of field and analytical data.
Monitoring locations should be assessed for representative conditions prior to collecting a water sample. For example, collection of a sample should target flowing water in riverine locations and avoid stagnant pools . If a monitoring location does not offer such conditions, a sample may still be collected, but field notes shall include observations such as pooled water, presence of algae (and volume estimates), and other biological conditions. It is recommended that City staff review available sample collection and handling resources [e.g., Caltrans Monitoring Guidance Manual 7 (Caltrans 2020), NPDES Stormwater Sampling Guidance Document 8 (EPA 1992)] prior to a monitoring event, and/or consult a water quality professional, as necessary. A brief synopsis of the key monitoring and flow measurement protocol are provided below in Section 4.1 and 4.2.
4.1 Manual Sample Collection
Manual sample collection involves filling a container from a runoff stream or receiving waterbody. This can be done either by collecting the sample directly into laboratory -supplied bottles or by using an intermediate container to pour the sample into the lab bottles. Note that samples for certain constituents, including oil and grease, bacteria, and low -level mercury, are best if collected directly into the appropriate sample bottle without use of an intermediate container to reduce the potential for cross contamination. However, in certain situations such as high flow it may not be feasible to collect directly into the sample bottle, therefore an intermediate container can be used to collect and transfer the sample.
An intermediate sample container can be an unused laboratory bottle.
Sample collection can be assisted by a device that is extended to dip, lower, or reach the sample container into the waterbody. This method is

Manual sample collection methods
using an intermediate container
SANITARY SEWER SPILL MONITORING PLAN
15275.05 15 MAY 2025
ordinarily used when the waterbody is difficult to access, and an intermediate container must be lowered into the water or reached across some distance to collect a sample. Additionally, the use of an intermediate container when filling pre-preserved laboratory bottles can be beneficial because it eliminates the risk of accidentally rinsing out the preservative while filling the bottles.
4.2 Flow Rate Estimation via Float Velocity Method
To use this method, first it is necessary to determine the cross-sectional area of the flow at a specific location. This requires estimation of flow depth and width, as well as a general assessment of the bottom channel shape such as rectangular or trapezoidal. Then field technicians mark two places on the bank of the channel at least five feet apart (using a longer distance between the two points will result in a more accurate flow measurement).
When this setup is complete, the flow can be measured by releasing a buoyant object into the channel upstream of the two marked points on the bank and measuring the time it takes to flow between them. The rate of flow can be calculated by the following formula:
Equation 1:
𝐹𝑙𝑜𝑤 𝑅𝑎𝑡𝑒 (𝑓𝑡3
𝑠𝑒𝑐⁄ ) = 𝐷𝑖𝑠𝑡𝑎𝑛𝑐𝑒 𝐵𝑒𝑡𝑤𝑒𝑒𝑛 𝑃𝑜𝑖𝑛𝑡𝑠 (𝑓𝑡)
𝑇𝑟𝑎𝑣𝑒𝑟𝑠𝑒 𝑇𝑖𝑚𝑒 (𝑠𝑒𝑐) × 𝐶𝑟𝑜𝑠𝑠 𝑆𝑒𝑐𝑡𝑖𝑜𝑛𝑎𝑙 𝐴𝑟𝑒𝑎 (𝑓𝑡2)
There are some disadvantages to the float method: (1) measuring the cross-sectional area of a large water body can be difficult, and inaccuracies in this value will affect the accuracy of the flow measurement, and (2) the method measures velocity of flow only at the surface of a channel, which may not be representative of the velocity throughout the entire cross section of flow. Therefore, when using this method, multiple measurements should be taken at different points across the channel and the results averaged.
The accuracy of the float method is improved by using an object that has a density similar to water and that tends to float totally submerged. For example, oranges are good floating objects for this method because they are easy to see, remain buoyant, and are environmentally safe.
The float method should only be used if a mechanical flow meter is not available. Mechanical flow meters, such as a turbine flow meter or ultrasonic flow meter, will provide more accurate flow velocity at a given point. The Cross- sectional area will still need to be estimated to calculate a flow rate , however, flow meters help reduce the time, effort, and potential inaccuracy introduced by the manual float method.
4.3 Monitoring Equipment
The use of proper monitoring equipment is necessary to ensure the safety of personnel collecting the samples and integrity of the samples themselves. Contact with raw sewage can have acute and long-term impacts to human health that can be avoided using the proper personal protective equipment (PPE). Additionally, contamination of the sample may occur if inappropriate equipment or handling methods are used.
Recommended PPE for receiving water monitoring includes:
• Disposable latex gloves
SANITARY SEWER SPILL MONITORING PLAN
15275.05 16 MAY 2025
• Close-toed shoes, long pants, and long sleeve shirt
• Optional Tyvek suit or similar if contact with the spill material is likely • Eye protection (glasses or goggles) and/or face shield • Disinfecting wipes and hand sanitizer
To be ready for a spill, it is recommended the following list of equipment is procured and stored in a centralized location. Store enough sampling bottles to be able to collect up to four days of samples at each of the four monitoring location types described in Section 2.4. In the event that any of the bottles are lost or compromised, it is recommended to also have a full set of backup bottles. • Four days’ worth of sample bottles plus one days’ worth of back-up includes:
o 40 100 mL plastic bottles with Sodium thiosulfate preservative o 20 250 mL plastic bottles with Sulfuric acid preservative • Sample bottle labels and water-resistant marker
• CoC sheets (Appendix B)
• Visual observation log (Appendix C)
• Cooler for ice to keep samples at or below 4°C
• Grab pole to safely reach into drains as needed
For additional resources, the Caltrans and/or EPA guidance documents referenced at the beginning of this section can serve as a general guide for collecting water quality samples. While these documents focus on stormwater sampling, the safety protocols and handling methods apply to the receiving water monitoring discussed in this plan.
4.4 Water Quality Laboratory
Monitoring samples must be taken to an Environmental Laboratory Accreditation Program (ELAP) certified laboratory for analysis. The City of Pasadena Water Quality Laboratory and Los Angeles Dept. of Water & Power, Water Quality Laboratory located in Pasadena are classified as non-public certified laboratories. The City should consider creating a purchase order with either of these laboratories to process monitoring results in case of a spill.
Otherwise, the closest public ELAP certified laboratory is in South Pasadena:
• EMSL Analytical, Inc. (public). Located at 520 Mission Street, South Pasadena.
In the event that the local laboratories are unavailable during a spill event , consult the State Water Resources Control Board ELAP webpage9 for a mapping tool that shows the closest laboratories and their contact information.

5 Site Access and Safety Considerations
Access to monitoring locations must be assessed for safety considerations during each visit. Field staff should use caution at all times in evaluating roadway safety and right of way conditions. Specific safety concerns relating to surface water sampling includes potential slip, trip, and fall hazards, biological hazards, and swift water. To reduce safety risks, grab poles should be considered for sample collection at difficult to reach monitoring locations.
Unlike receiving water monitoring locations, drainage conveyance monitoring locations are often located in the street and require some level of traffic control based on the type of road and time of day. Compounding this issue is that spills frequently occur during rain events which make for even more dangerous road conditions. Monitoring locations presented in this plan are intended to represent the most optimal location from a data standpoint, but not necessarily from a personnel safety standpoint. At all times, personnel safety should be the top priority, and monitoring should be delayed or relocated if safety is potentially compromised.
Site-specific access and safety considerations are presented in the following section. 6 Site Descriptions
Site-specific location, access, and monitoring considerations are presented on the following site information sheets.
For the purposes of this document, the core monitoring locations are identified using the name of the drainage and a designation of the monitoring location as upstream (US) or downstream (DS) or drainage conveyance (DC) . A numeric value is added to monitoring location name where there is two or more of the same type within the same drainage area.
As described in Section 3, spill monitoring locations are identified based on location and size of the spill, specific weather and hydrology conditions, and specific management considerations. A geographic reference for all sample location is provided in Figure 3.
6.1 Receiving Water Monitoring Locations
The following sections identify pre-determined US and DS surface water monitoring locations. Since we do not know the location of a potential future spill, the discharge point into the receiving water as well as the DC monitoring point are unknown. Therefore, specific locations for these samples cannot be pre-planned. US and DS monitoring locations can be pre -planned since they are best taken from where a water body enters a city before being influenced by runoff or non-stormwater discharges (i.e. sewer spills) and where a water body leaves a city before it comingles and is influenced by downstream conditions that are outside of the city’s control. Section 6.1.1 through
6.1.6 detail US and DS locations that fit these criteria as closely as possible. However, in certain situations, like with Alhambra and Rubio Wash and the eastern edge of Eaton Wash, there is not a receiving water present (channelized into storm drains). Therefore, DC monitoring locations as shown in Section 6.2.1 through 6.2.15 have been identified where the City may collect samples to categorize water in the storm drain before it crosses over the City boundary.

6.2 Drainage Conveyance Monitoring Locations
Portions of Pasadena, specifically in Alhambra and Rubio Wash and the far eastern edge of the City along Eaton Wash, do not have a receiving water location for the purpose of spill monitoring within city limits. Therefore, the City should consider identifying downstream drainage conveyance monitoring locations (typically in a storm drain manhole or inlet) just upstream of where the storm drains cross the City boundary. Monitoring at these locations will provide valuable data on the impact from spill that made its way into the storm before being influenced by runoff or other non-stormwater discharges from a downstream jurisdiction that’s outside of the City’s control.
The following sections provide overview maps and street view images for the downstream drainage conveyance system monitoring locations identified for Alhambra Wash, Rubio Wash and Eaton Wash . In Eaton Wash, the majority of the area can be monitored at the designed downstream monitoring location (EATON WASH_DS1) except for the eastern most edge of the drainage area that flows into Arcadia and East Pasadena. In this area, a designated drainage conveyance monitoring point is located in the storm drain at the intersection of Foothill Blvd and Michillinda Ave. In Alhambra and Rubio Wash, drainage conveyance monitoring locations have been identified for each storm drain that crosses the City boundary.

7 Summary
This Monitoring Plan provides the City with technical guidance for monitoring receiving water quality in the event of a sewer spill. Water quality monitoring can help the City determine the relative impact of a spill and help guide management decisions relating to remediation and spill response. These monitoring protocols, and site -specific descriptions, provide City staff with a detailed guidance document for performing water quality monitoring and assessing impact to waterbodies following a sewer spill.
Selection of the monitoring locations for this Monitoring Plan was determined based on proximity to City assets, drainage characteristics, safety, accessibility, and ability to isolate runoff from a spill that is only influenced by the City. This document provides multiple locations that may be used as downstream and upstream monitoring locations to assess, not only the downstream impacts of spills, but also the upstream pollutant characteristics to document the relative impact in each receiving water . Drainage conveyance and point of discharge monitoring locations will be determined in real time if a spill reaches the receiving water. All monitoring sites are subject to change should a different site be identified as preferable for properly characterizing impacts to water quality from a spill event. It is recommended that the City annually visit the monitoring locations identified in this plan to ensure access is still available and safe.
