1.2 SSMP Goal and System Management Objectives
The following SSMP has been developed by the City of Glendale (City) to comply with the General Order in each of these milestones. Moreover, the SSMP meets all requirements of the General Order while at the same time serving as a valuable reference tool for City staff. The City established the following goals during the development of this SSMP:
• Proper selection and training of personnel and safe execution of all maintenance activities.
• Eliminate preventable sanitary sewer spills that close beaches. • Minimize preventable sanitary sewer overflows.
• Reduce gallons of sanitary sewage that contact water ways from preventable sanitary sewer spills .
• Optimize use of post -work inspection.
• Extend the system’s useful life of the sewer system by proactively correcting structural deficiencies identified from assessment activities . • Reduce reporting compliance errors to zero.
These SSMP goals are supported by documentation and modification procedures that will assist City staff as they implement the SSMP and complete the SSMP goals on a year-by-year basis. The goals are ambitious, but due to the pro -active and forward- looking management of the sewer system already practiced by the City, they mainly represent an enhancement in the documentation and review of sewer system management activities that are already performed by City staff. As such, these goals are appropriate and ach ievable.
These procedures will allow the sewer system to maintain reliability and capacity into the future, and enable the City to meet its strategic sewer system goals.
1.3 SSMP Update Schedule
Pursuant to the General Order, the City conducts program monitoring and triennial audits of its SSMP , prepares SSMP updates, and implements planned activities to achieve the City’s collection system program objectives. This SSMP update was prepared upon completion of the most recent SSMP Program Audit dated October 30, 2024.
The schedule for auditing and updating th is SSMP is provided in Table 1-2 and also discussed in SSMP Element 10, Section 10.1 .

A comprehensive set of sewer maps show all the features of the City’s sanitary systems .
These maps have been converted to electronic GIS maps that are used in the field for locating pipelines, maintenance holes, service connections and other features of the City’s system. These maps are maintained and kept up-to-date through an efficient workflow involving field crews, operations and maintenance staff, and GIS professionals.
Crews use Cityworks on their iPads to access sewer maps and provide electronic markups when discrepancies are found . They capture screenshots, annotate them with marking tools, and email the updates to the Wastewater Crew Supervisor, who forwards them to the GIS team. A dedicated GIS professional then reviews and edits the maps to accurately reflect the changes, typically completing updates within a day or two. Once finalized, the updated maps are made available to staff, ensuring th at the city's sewer infrastructure records remain current and reliable. When the sections sanitary sewer system are updated as part of a CIP, as -builts are used to update the GIS map in Cityworks.
4.1.1 Procedures for Maintaining and Providing Access to Water Boards Staff
State Water Board or Regional Water Board staff can gain access to system mapping by contacting a Legally Responsible Official for the City of Glendale, Dan Hardgrove or Roy Rodriguez, using the contract information provided in Section 2.2.
4.1.2 Procedures for Maintaining and Providing Access to City Field Staff
Collection system field staff have access to Cityworks on smart devices . For operation and maintenance, customized GIS datasets of the sewer system are used in work prioritization and decision -making processes. If any system defects are observed during routine maintenance checks , maintenance crews use Cityworks create electronic markups on devices in the field to communicate necessary updates to sewer mapping.
All updates are performed by a GIS professional .
4.2 Preventative Maintenance Program
The City employs several sewer maintenance program strategies to manage the collection syste m, and uses of a computerized maintenance management system (CMMS) and Standard Operating Procedures, along with equipment -specific manuals, to guide the frequency of sewer cleaning and pump station maintenance. Task schedules are based on operational experience, past p erformance, manufacturer recommendations, and site -specific conditions.
The City’s maintenance program includes preventive, proactive, and corrective maintenance, along with control. Table 4-1 outlines preventive operation and Sewer System Management Plan

The City employs several sewer maintenance program strategies to manage collection system performance. These strategies include:
• System-Wide Cleaning: The City has organized its 360 miles of gravity sewer mains into 12 cleaning districts, with a goal of completing a full cleaning cycle every 18 months. To achieve this target, crews clean approximately 240 miles of sewer mains each year.
• Trouble Spot Cleaning: The City proactively identifies pipe segments with recurring issues and places them on a Trouble Spot list. These high-maintenance areas are cleaned at scheduled intervals of 2, 3, 4, 6, or 12 -month flush intervals. To optimize internal resources, the City pauses Trouble Spot cleaning in December to focus on Restaurant Runs, described further below. Overall, the Trouble Spot cleaning program covers approximately 40 miles of sewer mains annually . • Restaurant Runs: Each winter, the City conducts targeted cleaning of sewer pipelines prone to grease accumulation, particularly those receiving discharges from food service establishments (FSEs). This effort also includes other facilities that contribute to grease buildup, such as convalescent homes and adult daycare centers, ensuring the system remains free of blockages and operates efficiently. • Targeted Root Control: The City has a list of pipe segments with known root intrusion issues and performs either mechanical root removal (i.e. Trouble Spot Sewer System Management Plan
2025 SSMP Update
14 | FINAL - April 11, 2025
cleaning) or chemical root control using contract root control application services.
Chemical root control is performed in addition to sewer cleaning activities and is not used as the primary means to manage pipe segment performance. This work is performed using contract services with City staff providing contract management including planning, contractor oversight and contractor field support. Roots are causing approximately 70 percent of the City’s sewer overflows. The City is using a combination of mecha nical cleaning and chemical root control to manage pipelines with significant root intrusion issues. Additionally, the City takes a proactive approach by identifying pipelines prone to root intrusion and prioritizes them for repairs or rehabilitation, eliminating root -related issues at their source. • Manhole Inspection: Each manhole is inspected at least once every 18 months. If Operations & Maintenance (O&M) staff or contractors identify issues such as a cracked rim or cover, a damaged shelf, or other structural concerns, they document the condition with photographs and notify the Engineering team via email. This notification initiates a Level 1 inspection, during which Engineering staff conduct a detailed assessment to determine the severity of the issue and recommend appropriate corrective actions. A n example of the Level 1 Inspection Form is provided in Attachment D1.
• Cleaning Quality Control Inspections (Spot Checks): The City conducts CCTV inspections of recently cleaned pipe segments to assess cleaning effectiveness and identify opportunities for improving maintenance practices. This program is operator - driven, initiated when staff detect issues during routine system -wide cleaning. Pipes requiring further evaluation are referred for CCTV inspection to ensure proper maintenance and identify any necessary corrective actions. • Investigative and Operational Support CCTV Inspection: The CCTV crew inspects issues identified by Wastewater Maintenance to determine the root cause of the issue. The results are used to determine the best course of action to address the issue, if an issue exists.
• Street Resurfacing Capital Project CCTV Pre-Inspection: The CCTV operation supports the Engineering Division's street resurfacing program with pre -work condition assessment of collection system assets located below streets designated for resurfacing. To minimize disruptions, most inspections are performed outside regular hours. Lower traffic streets are inspected during afternoon and evening shifts (typically 4 :30PM – 9:30PM) without impacting day -shift productivity. High traffic streets are inspected betw een midnight and 6: 00 AM, with the three-person crew continuing work until 11:00 AM the same morning. To manage workload, staff operates under a self -imposed limit of two early morning shifts per week, one of which must be Thursday midnight into Friday morning. This shift must be staffed by personnel who would typically be off that Friday, ensuring balanced scheduling between A- and B-week staff rotations .
• CCTV Condition Assessment Program: Multi-year project. The City is currently in the middle of a multi -year project to televise all 360 miles of the City’s sewer pipelines. The project will be completed in the following three phases:
o Phase 1 – 95 miles - COMPLETED
Sewer System Management Plan
2025 SSMP Update
FINAL - April 11, 2025 | 15
o Phase 2 – 169 miles. Started in January 2024 with planned completion by June 2025.
o Phase 3 – 96 miles. Planned start in July 2025 with planned completion by June 2027.
Once complete, the City will evaluate the CCTV data to identify the next set of pipe repairs and pipe segment rehabilitation and replacement projects to build into the 10 - year CIP program. The City will coordinate these projects with the projects identified in the upcoming Sewer Master Plan update commencing in the 2026-2027 timeframe.

7 Sewer Pipe Blockage Control Program
Approximately 85 percent of spill events in the City’s sewer system over the past three years are attributed to blockages caused by roots (17), debris (4) or grease (1). The City primarily manages root intrusion and debris sedimentation using a preventive maintenance sewer cleaning strategy. Grease accumulation is managed using both a source control strategy and a preventive maintenance sewer cleaning strategy.
7.1 Source Control Program Overview
The City of Glendale has over 600 food service establishments (FSEs) and has a goal to inspect each FSE at least once every 18 months. The City provides best management practices guidance to FSEs, reviews maintenance records for FSEs, and checks grease removal equipment for conformance with maintenance requirements (i.e., 25 percent rule). Each inspection requires approximately 45 to 60 minutes at the site. Additional time is required to process inspection documentation and resulting inspection findings in cases where FSEs fail an inspection. Minor non -conformances can usually be resolved with a follow -up phone call and transmittal of proof of compliance. Major non - conformances and violations typically require a return inspection.
The City’s FOG Control Program demonstrates the City’s pro -active approach to management of the sanitary sewer system, and helps reduce the amount of fats, oils and grease discharges to the sanitary sewer system, by including:
• A plan and schedule for the disposal of FOG generated within the sanitary sewer system service area and a list of acceptable disposal facilities. • Legal authority to prohibit discharges to the system and identify measures to prevent SSO’s and blockages caused by FOG.
• Requirements to install grease removal devices, design standards for the removal devices, maintenance requirements, BMP requirements, record keeping and reporting requirements.
• Authority to inspect grease producing facilities, enforcement authorities, and staff to inspect and enforce the FOG Ordinance.
• Identification of sanitary sewer system sections subject to FOG blockages and establishment of a cleaning maintenance schedule for each section. • Development and implementation of source control measures for sources of FOG discharged to the sanitary sewer system for each pipe segment found with grease accumulation.
• Implementation of a plan and schedule for a public education outreach program that promotes proper disposal of FOG.

7.2 Implementation Plan and Schedule for Public Outreach
7.2.1 Summary of Outreach Activities
The City has developed a public education program that promotes proper disposal of FOG. This program includes letters to customers on appropriate FOG disposal and letters to plumbing professionals describing adequate maintenance techniques to prevent fats, oils, grease, rags and debris from entering the City's sanitary sewer lines.
To increase the amount of information available to customers, the City has developed an instructional mailer to be included in billing correspond ence each year.
7.2.2 Industrial Waste Program
In 1996, the City consolidated the Industrial Waste Program with the Fire Departments hazardous material operation within the functions of the Environmental management Center. The objective of the industrial waste program is to prevent hazardous materials from di scharging into the sanitary sewer system through comprehensive permitting, inspection and sampling. Industrial wastewater is regulated by Section 307 of the Federal Water Pollution Control (also known as the Clean Water Act) and the Glendale Municipal Code.
Beginning in early 2019, the Public Works Maintenance Services Division began administrating Industrial Waste Permits for FSE’s only. At this same time the permit application for FSE’s was simplified to reflect the narrower range of constituent waste coming from an FSE. The City of Glendale Public Works Department administers the FOG Ordinance and inspects FSE’s on an 18 -month schedule to ensure compliance.
Inspectors for the City of Glendale Public Works Department have the authority to enter food service facilities (FSE) to inspect flow and constituent control devices (including grease traps, hydro -mechanical devices and grease interceptors), and inspect maintenance records.
7.3 Plan and Schedule for Disposal of FOG within the
Service Area
FSEs contract directly with grease haulers to collect grease from FSEs and to properly dispose the grease . The City requires grease to be disposed of properly. FSEs are required to record of all manifests, receipts and invoices of all cleaning, maintenance, grease removal from pretreatment devices, hauling and disposal of waste , and cleaning of pretreatment facilities, such as grease traps, by facility employees. The record must log the date and time of cleaning, the name of the employee who performed the cleaning and the volume removed. The City’s

8 System Evaluation, Capacity Assurance and
Capital Improvements
8.1 System Evaluation and Condition Assessment
8.1.1 Evaluation of Sanitary Sewer System Assets
The City uses the following procedures to evaluate sanitary sewer systems assets .
Sewer Pipelines: The City uses Closed-Circuit television (CCTV) inspection to evaluate sewer pipelines. The City has one in-house CCTV crew focused on investigative inspection s and quality control inspections of sewer cleaning activities. The City is also performing CCTV inspection of all sewer pipelines over a 3 -year period using contract CCTV services.
Sewer Manholes: City cleaning crews open and visually inspect the upstream and downstream manhole when a sewer pipe segment is cleaned. When a significant structural defect is observed, the sewer cleaning crew will refer the manhole for repair. In addition, Engineering will inspect all manholes included within a sewer pipeline rehabilitation and replacement project to determine if sewer manhole repair, rehabilitation or replacement needs to be included within the project scope.
Doran Pump Station : Doran Pump Station is periodically inspected by third party contractor s. Recent improvement to Doran : SCADA, pumps, emergency bypass, electrical approximately 2015. The station was overhauled in 2010-2011 and bypass piping was set up in 2015. The pump station has 2 spare pumps. Maintenance contract s are in place for pump repair and preventative maintenance checks .
8.1.2 Condition Assessment Strategy
The City is inspecting the entire sewer system over a 3 -year period to document a baseline condition for all sewer pipelines. The City has divided baseline CCTV inspection into three phases: Phase 1 will inspect 95 miles, Phase 2 will inspect 169 miles, an d Phase 3 will inspect 96 miles. All phases will be completed by June 2027.Once the initial baseline is completed, the City will be developing a re -inspection schedule for all pipelines based on current state condition. The re -inspection schedule for all p ipelines will be developed and included in the next Sewer System Management Plan update in May 2031.
8.1.3 Inspection and Condition Assessment Prioritization The primary driver of CCTV inspection prioritization includes past failure events, known maintenance issues, age , material, and district. The City included all p ipes with past failure events and known maintenance issues in the 95 miles of Phase 1 CCTV inspection. Phase 2, which includes 196 miles of CCTV inspection, will inspect the older areas and materials within the City. Phase 3 , which includes all remaining 96 miles of pipes in the sewer syste m, will include all of the newer pipelines.
Sewer System Management Plan
2025 SSMP Update
FINAL - April 11, 2025 | 25
The City will review the CCTV inspection data and will prioritize evaluation and planning activities on areas with pipe segments with past failure events, known maintenance issues, and significant structural issues.
All spills from the City’s sewer system reaching the storm drainage system are conveyed directly to the Los Angeles River or to the Verdugo Wash and then to the Los Angeles River. Therefore, all pipelines in the system have a similar environmental impact if not intercepted and recovered.
8.1.4 Assessment of System Conditions
Engineering reviews CCTV inspection data for pipe segments with past failure events, known maintenance issues, and significant structural defects to identify sewer repair, rehabilitation and replacement needs.
The potential for subsurface leakage from the sewer system to the storm drainage system, Verdugo Wash or Los Angeles River is minimal. Storm drainage pipelines a re constructed at a higher elevation than the City’s sewer pipelines. The Verdugo Wash and Los Angeles River are concrete-lined drainage channels with no likelihood of subsurface leakage entering these waterways. Engineering will review the structural condition of pipe segments within 50 feet of these waterways and will identify repair, rehabilitation or replacement of pipe segments with severe structural defects with potential for subsurface leakage. Severe structural defects include NASSCO PACP Structural Grade 5 defects such as pipe collapse, broken void visible, broken soil visible, hole void visible, hole soil visible , and missing wall .
8.1.5 Inspection and Assessment Recordkeeping
CCTV inspection observations and videos are all maintained in GraniteNet . GraniteNet is a cloud -based CCTV software enabling City staff to access from any computer in the City. GraniteNet is also GIS -based, enabling results to be easily linked with the City’ s GIS-based computerized maintenance management system (i.e., Cityworks). Results from CCTV are easily accessed and viewed by staff.
8.1.6 Assessing Assets Vulnerable to Climate Change
The City performed a high -level review of assets vulnerable to climate change during the 2024 SSMP audit. The high-level review resulted in the f ollowing findings:
• Sea level rise: The City is several hundred feet above sea level and is not impacted by sea level rise.
• Flooding: The City does have some areas susceptible to flooding. A vulnerability exists if these manholes are opened during a flooding event. • Erosion Due to Intense Rain Events: The City has built a robust storm drainage system and does not own any pipelines in canyons or near streams that are susceptible to erosion due to intense rain events.
• Wildfires: Wildfire is not an issue for the gravity sewer system. The location of Doran Pump Station is not susceptible to wildfire.
Sewer System Management Plan
2025 SSMP Update
26 | FINAL - April 11, 2025
• Power Disruption: The Doran Pump Station is susceptible to power disruption. The City has mitigated this vulnerability with an backup power generator with 1,000 gallons of fuel providing 72 hours of power. The Doran Pump Station can be affected by power outages; however, the City keeps a 1 000-gallon generator for backup power and is working towards a larger a backup power source.
8.2 Capacity Assessment and Design Criteria
In 2020, the City completed an update to their Wastewater Master Plan (WWMP), which included the development of a computerized hydraulic model for the City’s wastewater system. This model was used to perform hydraulic analyses to assess the performance of the existing wastewater system under dry and wet weather conditions, evaluate the impact of future growth, and recommend improvements that may be needed to provide the needed capacity under both existing and future conditions. The goal of the hydraulic model development and system evaluation was to:
• Determine additional infrastructure requirements for resolving current model - predicted hydraulic capacity limitations,
• Evaluate the system under both dry weather and wet weather flows for the current conditions and future planning horizons, and
• Identify infrastructure needed to resolve limitations.
8.2.1 Procedures for Identifying and Addressing Hydraulic Deficiencies and Capacity Limits
Dry-Weather Peak Flow Conditions that Cause or Contribute to Spill Events Existing average dry weather flow (ADWF) was determined by using flow monitoring data to analyze the dry days only. A dry day is defined as a day when no rainfall occurred 72 hours prior to that day and when there were no lingering effects from a previous rainfall. The average hourly dry-weather flow rate for each of the flow meters reflects the dominant LU that drains to each meter. ADWF diurnal patterns were derived from hourly flow data recorded by the City’s permanent and temporary flow monitors or meters installed in the wastewater collection system as part of a flow monitoring program.
To calculate peak flows, ADWF was used and multiplied by an appropriate peaking factor ( PF). The PF was established based on the data gathered during the conduct of the 2019 Wastewater Flow Monitoring Program. To create the PDWF scenario, which models the peak flow experienced in the collection system under dry conditions, the base wastewater flow (BWF) component is peaked to account for the variation in wastewater generation that occurs over the course of a typical day. This peaking is accomplished by applying diurnal curves to the BWF.
Appropriate Design Storm or Wet Weather Event Criteria
Evaluation of the City’s wastewater collection system during dry and wet weather conditions involves evaluation of both capacity and general operational issues. The dry weather flow in the system is primarily controlled by population and significant commercial/ industrial dischar gers. Operational issues that may lead to inadequate level Sewer System Management Plan
2025 SSMP Update
FINAL - April 11, 2025 | 27
of service system performance include roots, fats, oils, and grease. The model evaluates the system as designed, assuming clean pipes. The hydraulic model is an important utility management tool to assist in identifying locations of capacity constraints or velocity concerns that may exist in the existing system, or are project ed to arise under future dry or wet weather flows. The primary design criteria used to evaluate potential pipe capacity or operational problem areas are shown in Table 8-1.

Depth of flow in relation to pipe diameter, or depth -to-diameter (d/D) ratio is an element of the City’s existing design criteria and is used to identify potential capacity problems within the system. It is important to note that the current state and feder al regulations require wastewater agencies to accommodate the impact of wet weather events on their system through the development and use of a wet weather analysis. Design storms are primarily defined by their hyetograph, duration and the return period. The hyetograph is the representation of temporal variation of storm intensity. Duration is the amount of time over which a rain event occurs, where the return period is a measurement of the likelihood a particular event will occur. For example, a 5 -year storm will theoretically occur once every 5 years.
Because the selection of the design storm can have a significant impact on determining the adequacy of system capacity, this design criteria driven level of service element of the Master Plan had careful consideration in this planning effort. To provide the City with the necessary information to make an appropriate decision, both 5 - and 10-year design storms were discussed with the City. Based on discussions with City staff, the design storm selected to be incorporated in the hydraulic model simulation was a 10-year 24- hour event. A 10-year 24-hour design criterion is more conservative criteria than has been used in the past. This criterion is also being used by several agencies in southern California including the City of L os Angeles and the City of Santa Monica in the ir hydraulic capacity programs to contain peak wet weather flows in the sewer system to avoid spills .
Capacity of Key System Components
Under existing dry and wet weather flow conditions, a large majority of the City’s wastewater collection system pipelines have excess or reserve capacity. The existing hydraulic modeling simulation identified less than two percent of the total wastewater pipeline system had d/D ratios greater than the system performance evaluation criteria.
Sewer System Management Plan
2025 SSMP Update
28 | FINAL - April 11, 2025
This finding indicates the City’s wastewater system has available capacity in the majority of the local wastewater system.
Similarly, the hydraulic analysis of the depth of wastewater within the maintenance hole (MH) structure indicated that the majority of these structures fell within the evaluation criterion for surcharge depths. Maintenance hole surcharge depths are calculated by the hydraulic model under both dry and wet weather conditions.
The results of the hydraulic analysis of the pipeline network under existing wet weather design storm conditions are shown in Table 8-2, and depicted graphically for d/D ratio and MH performance findings on Figure 8-1 and Figure 8-2, respectively . Areas of potential high -risk surcharging are also reflected in Figure 8-2. As shown, the City’s wastewater system operates well under current peak dry and peak wet weather conditions and has minimal areas of potential capacity limitations .

Major Sources Contributing to Peak Flows Associated with Sewer Spills PWWF is estimated as PDWF plus RDI/I and BWI, combined as a single inflow/infiltration (I/I) value herein. RDI/I is stormwater that enters the wastewater collection system in direct response to the intensity and duration of individual rainfall events. RDI/I may recede gradually after a storm; however, any residual flow is considered to be a general increase in GW I. Figure 8-3 shows the peak measured flow schematic derived from the flow monitoring program.
Figure 8-3. Peak Measured Flow Schematic
Based on the flow monitoring data collected from the various basins during the 2019 Wastewater Flow Monitoring Program , site-specific measured flows were obtained and new PFs were established. These findings are shown in Table 8-3.

Flow monitoring basins are localized areas of a wastewater collection system upstream of a given location (often a flow meter), including all pipelines, inlets, and appurtenances.
The basin refers to the ground surface area near and enclosed by the pipelines. A basin may refer to the entire collection system upstream from a flow meter or may exclude separately monitored basins upstream. I/I analysis was conducted on a basin -by-basin basis. For this study subtraction of flows was required to isolate the drai nage areas of some flow monitoring basins. The flow monitoring basins and basin isolation equations used to define the limits of the basin boundaries are listed in Table 8-4.

8.2.2 Capacity Assessment Considerations
Data from Existing Condition Assessments, Maintenance and Other Available Information
Engineering considers data from sewer pipeline condition assessment s, system inspections, spill history and other available information during pro ject planning and formation to bundle and prioritize CIP projects.
Capacity of systems subject to flooding and increased infiltration and inflow due to larger and/or higher-intensity storm events as a result of climate change The City performed flow monitoring in 2019 and measured site -specific flows , including areas impacted by flooding or inflow and infiltration, to establish new peak flows within the sewer system. The City used these new peak flows to update and calibrate the City’s hydraulic model , which was then used to perform system capacity analysis to identify potential capacity deficien cies documented in the 2020 Wastewater Master Plan.
Sewer System Vulnerability to Erosive Forces in Canyon and Streams The City has built a robust storm drainage system and does not own any pipelines in canyons or near streams that are susceptible to erosion due to intense rain events.
8.3 Prioritization of Corrective Action s
Corrective actions a re prioritized based on the following classes . • Capacity Projects: These are capacity -related improvement projects identified in the Wastewater Master Plan. The City derived these projects using the hydraulic model
Sewer System Management Plan
2025 SSMP Update
FINAL - April 11, 2025 | 37
to evaluate the response of the wastewater system under existing and future peak wet weather conditions.
• Pipeline Replacement and Renewal Projects : These rehabilitation projects and programs are identified by Engineering to remediate pipelines with known condition deficiencies to establish a condition assessment and pipeline renewal program to promote long -term system reliability.
8.3.1 Sewer Pipeline Condition Remediation Prioritization Engineering reviews sewer pipeline CCTV and assigns an A,B or C rating. • An “A” rating is assigned to pipe segments with imminent issues such as deformed pipe, voids, or pipes with recurring failures.
• A “B” rating is assigned to pipe segments with significant structural issues such as step-up offsets that restrict flow or trap debris or broken pipe resulting in pipe wall movement or an irregular pipe cross -section.
• A “C” rating is assigned to structural defects that can be ad dressed at the City’s discretion . This includes low spots, pipe sags, and mismatched merging flows. These issues are managed using preventive maintenance until a long -term solution is delivered to remove these defects from the system.
8.3.2 Sewer Capacity Remediation Prioritization and Additional CIP Considerations
Potential capacity improvements identified under existing peak wet weather conditions have a higher priority than the additional pipelines that were adequate under existing conditions, but needed additional capacity to meet future system flow conditions. In addition to the individual prioritization of capacity -related projects, other key factors have been integrated in the overall prioritization process. While some of these factors are external to the performance of the City’s Wastewater Enterprise, they w ill influence the timing and potential cost aspects of the program’s implementation and have an influence on the level of community disruption and overall quality of life in Glendale.
These implementation elements include spatial demand triggers that link to CIP requirements and associated development projects, inclusion of a broader infrastructure management perspective by coordinating the CIP with other projects (e . g., underground utility and paving projects) to minimize community disruption, consideration for cost segregation so that growth pays an appropriate share of costs, and an effort to develop a leveled CIP to match the programmed improvements with capital budgeting and ratepayer affordability and acceptance . The important end-result of this planning effort is the identification of a comprehensive CIP that is:
• Time-phased to support needed budgetary considerations, • Work plan based to confirm and field verify system facility data to maximize the use of available funds and attain operational concurrence,
• Flow-based to react to specific spatial triggers for implementing "just in time" design and construction,
Sewer System Management Plan
2025 SSMP Update
38 | FINAL - April 11, 2025
• Holistic through the integration of broad community infrastructure management considerations including utility pipeline replacement efforts and programmatic street management services, and
• Affordable by matching the current program with the current level of capital funding and allocating these funds across the variety of improvement program activities.
By proceeding in the purposeful manner, the resulting CIP program provides the City with a proactive and adaptive plan for a reliable wastewater collection system.
8.4 Capital Improvement Plan
8.4.1 CIP Project Schedule and Funding Sources
Currently, the sewer CIP includes two upcoming projects to televised the remainder of the sewer system. Once completed, t he CCTV data will be used to identify the next set of sewer repair, rehabilitation and replacement projects. The City is also planning to initiate an update to the Sewer Master Plan in late 2025.

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.
3.3.2. State Water Board Sources of Drinking Water Policy On May 19,1988, the State Water Board adopted Resolution 88-63 (amended on February 1, 2006), titled Sources of Drinking Water, establishing state policy that all waters of the State, with certain exceptions, are suitable or potentially suitable for municipal or domestic supply.
3.3.3. State Water Board Cost of Compliance Resolution
On September 24, 2013, the State Water Board adopted Resolution 2013-0029, titled Directing Actions in Response to Efforts by Stakeholders on Reducing Costs of
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
15 Compliance While Maintaining Water Quality Protection. Through this resolution, the State Water Board committed to continued stakeholder engagement in identifying and implementing measures to reduce costs of compliance with regulatory orders while maintaining water quality protection and improving regulatory program outcomes.

1 Authority
As part of the Clean Water Act, the U.S. Environmental Protection Agency implemented the National Pollutant Discharge Elimination System (NPDES) program to reduce contamination of the nation’s surface waters. Issued in 1996 and renewed in 2001 and 2012, the Los Angeles Regional Water Quality Control Board issued a Municipal Storm Water Permit to the County of Los Angeles and 84 co -permittees which includes t he City of Glendale. The City of Glendale has developed this Spill Emergency Response Plan (SERP) to fulfill the National Pollutant Discharge Elimination System (NPDES) requirement. This plan also fulfills the requirement of State Water Resources Control Board Order WQ 2022-103-DWQ Statewide Waste Discharge Requirements General Order for Sanitary Sewer Systems, Attachment D - Sewer System Management Plan, Section (6) Spill Emergency Response Plan.
2 Introduction to Sanitary Spills
2.1 Sanitary Sewer Spills:
The Spill Emergency Response Plan (SERP) is designed to ensure that every report of a sewage spill is immediately dispatched to the appropriate crews so that the effects of the spill can be minimized with respect to impacts to public health and the environment.
This document outlines the spill response procedure to be followed by sewer maintenance employees and other responders when responding to a potential or actual sewage spill.
A spill is a discharge of sewage from any portion of a sanitary sewer system due to a sanitary sewer system operational failure, and/or infrastructure failure. Exfiltration of sewage is not considered to be a spill under the General Order if the exfiltrated sewage remains in the subsurface and does not reach a surface water of the State.
The Public Works Division shall act upon every reported sewage spill directly affecting or potentially affecting public or private property within the City of Glendale.

Spill Emergency Response Plan
Table 2-1: Spill Categories and Definitions
Spill
Category
Definition
Category 1 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.
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 an Enrollee -owned and/or operated lateral that discharges to a surface water is a Category 1 spill; the Enrollee shall report all Category 1 spills per section 3.1 of Attachment E1 (Notification, Monitoring, Reporting and Recordkeeping Require ments) of the General Order.
Category 2 A Category 2 spill is a spill of 1,000 gallons or greater, from or caused by a sanitary sewer system regulated under 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.
Category 3 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.
Category 4 A Category 4 spill is a spill of less than 50 gallons, from or caused by a sanitary sewer system regulated under this General Order that does not discharge to a surface water.
A spill of less than 50 gallons that spills out of a lateral and is caused by a failure or blockage in the sanitary sewer system is a Category 4 spill.

2.2 Objectives
The primary objectives of the SERP are to protect public health, to protect the environment, to satisfy regulatory agencies and waste discharge requirement conditions which address procedures for managing sewer spills, and to minimize risk of enforcement actions against the City of Glendale due to violations.
Additional objectives include:
• Provide excellent customer service.
• Protect private and public property from damage.
• Maintain a proper recordkeeping system to track problematic areas as well as to fulfill regulatory requirements.
2.3 General Order Requirements for a Spill Emergency
Response Plan
The Plan must include an up -to-date Spill Emergency Response Plan to ensure prompt detection and response to spills to reduce spill volumes and collect information for prevention of future spills. The Spill Emergency Response Plan must include procedures to:
• Notify primary responders, appropriate local officials, and appropriate regulatory agencies of a spill in a timely manner;
• Notify other potentially affected entities (for example, health agencies, water suppliers, etc.) of spills that potentially affect public health or reach waters of the State;
• Comply with the notification, monitoring and reporting requirements of this General Order, State law and regulations, and applicable Regional Water Board Orders; • Ensure that appropriate staff and contractors implement the Spill Emergency Response Plan and are appropriately trained;
• Address emergency system operations, traffic control and other necessary response activities;
• Contain a spill and prevent/minimize discharge to waters of the State or any drainage conveyance system;
• Minimize and remediate public health impacts and adverse impacts on beneficial uses of waters of the State;
• Remove sewage from the drainage conveyance system;
• Clean the spill area and drainage conveyance system in a manner that does not inadvertently impact beneficial uses in the receiving waters; Spill Emergency Response Plan
Glendale Public Works – Maintenance Services

Spill Emergency Response Plan
• Implement technologies, practices, equipment, and interagency coordination to expedite spill containment and recovery;
• Implement pre-planned coordination and collaboration with storm drain agencies and other utility agencies/departments prior, during, and after a spill event; • Conduct post -spill assessments of spill response activities; • Document and report spill events as required in this General Order; and • Annually, review and assess effectiveness of the Spill Emergency Response Plan, and update the Plan as needed.
2.4 Post Spill Response
For every sewer spill or potential sewer spill on public or private property coming from the city’s sewer system, the following guidelines shall be followed. • Immediate dispatch to appropriate crews upon receipt of report of a spill. • The first responder on scene shall do a visual assessment of the area to determine the nature, location, and type of problem. The first responder on scene shall confirm the existence of a spill and if other than the Standby Team Leader, will confirm the existence of a spill to a Standby Team Leader.
• The Standby Team Leader shall direct responding crew members to bring needed equipment to appropriate locations to recover spilled sewage and to relieve the cause of the spill.
• The responding crew members shall contain the spill, correct the cause of the spill and clean up the spill site in a timely manner.
• Proper documentation, and notification(s) shall be completed as soon as possible, including notification of the County Health Department within 15 minutes of the first responder’s arrival on scene and the California Office of Emergency Services (C al OES) within two (2) hours of becoming aware of a Category 1, 2, or enrollee owned lateral Spill greater than 1000 gallons.
• After every spill the City must do an assessment and review of all the previous spill response steps.
2.5 Record Keeping and Tracking
All Service Requests will be documented by Maintenance Services using the City Works software.
Any actual sanitary sewer spill will be documented on the Sewer Spill Field Worksheet which is part of the Stoppage Report . The Worksheet will be completed in the field by one of the responding crew members. The Stoppage Report will be completed in the Wastewater Shop. The Stoppage Report will be forwarded directly to the Wastewater Superintendent, as soon as the Draft Report has been created in the California Integrated Water Quality System (CIWQS) Database. The Wastewater Superintendent Spill Emergency Response Plan
Glendale Public Works – Maintenance Services

will then use the Stoppage Report in the process of readying the Draft Report for certification.
3 Standard Spill Response Procedure
The following decisions and procedures are summarized for reference in the City of Glendale’s Sewer Spill Emergency Response Flowchart.
3.1 Handling the Service Request/Complaints:
A spill may be detected by City employees or by others (e.g., general public). The Public Works Call Center is the primary recipient of telephone calls from the public regarding possible sewer spills from the sanitary collection system, The Maintenance Ser vices Division -Wastewater Section is responsible for responding to and mitigating spills.
The telephone operator/dispatcher should obtain all relevant information available regarding the spill including:
• Time and date call was received.
• Specific location.
• Description of problem.
• Any reference to a possible earlier start time for the event prior to the call time noted in 1. above.
• Caller’s name and phone number.
• Observations of the caller (e.g., odor, duration, back or front of property); and • Any other relevant information that will enable the responding investigator and crews, if required, to quickly locate, assess and stop the spill.
Note: Reference the Maintenance Services Division Standard Operating Procedure- Sanitary Sewer Spill Narrative and Talking Points which is an attachment to this Spill Emergency Response Plan.
Based on the service request information, and location of the problem, a crew will be dispatched.
3.2 Dispatch of Appropriate Crews to Site of Reported
Sewer Spill
Failure of any element within the wastewater collection system that threatens to cause a sewer spill triggers an immediate response to isolate and correct the problem. Dispatch of crews to any site of a reported sewer spill shall be done immediately. The r eport of a sanitary sewer spill should always be dispatched to the Standby Team Leader. While a Wastewater Crew Supervisor may or may not be available on any given day there is always an assigned Standby Team Leader.

Spill Emergency Response Plan
3.3 Spill Correction, Containment, and Clean-up
The following procedures shall be followed in response to sewage spills within the City of Glendale.
1. Site Assessment and initial response (performed by first person on scene). a. Do a visual assessment of the area .
b. If the visual assessment reveals other than a sewer -related problem, attempt to contact the service requestor for further information. Call -off other Wastewater Section personnel in route to the scene and if possible, determine the nature of the problem and relay the matter to the appropriate response group within the City.
c. If the visual assessment reveals a sewer spill, observe direction/location of spill flow or ponding, and determine if additional personnel or special equipment will be needed.
d. Call the Los Angeles County Health Department (LACHD) – within 15 mins of first responders’ arrival on scene. Phone number on the Sewer Spill Field Worksheet.
Special Notification Notes:
• If the spill is outside City limits, Section representatives shall notify the appropriate agency as soon as possible. See agency phone numbers attached. • If the spill has the potential to impact students at a school, the Standby Team leader shall inform the Maintenance Services Division office and identify the affected school(s). The office personnel shall contact the school principal by telephone to inform the school of the potential health risks and ask that students and staff be advised to stay away from posted area. Proper signage must be posted warning of possible health effects.
2. Begin Initial Containment of the Sewage Spill – Possible options:
a. Direct the flow into a nearby manhole.
b. Build a sandbag dike in the gutter line.
c. Vacuum truck recovery once combination flusher unit on site.
3. Set Up Traffic Control – Ensure that delineation is appropriate for the street speed and configuration of the work area.

(See Note 2 at the end of this section)
5. Continue Containment Efforts
a. Direct the flow into a nearby manhole to return sewage back to the sewage system.
b. If necessary, plug a catch basin and direct the flow into catch basin. c. Recover impounded sewage in catch basins or behind dikes with a vacuum truck.
d. If prolonged spill conditions are expected, a bypass pump operation is put in place.
6. Recover Downstream – As quickly as practicable, move to a point downstream in the receiving storm drainage conveyance system and attempt to recover as much of the sewage that entered the storm drainage conveyance system as possible.
7. Post Community Warning Signs – If a spill is occurring where the public could possibly be exposed, post warning signs on barricades along the area of potential public exposure to sewage discharge.
8. Clean-up Operations – Spill sites are to be thoroughly clean after a spill. No identifiable residue shall remain.
a. Cleaning products and other chemicals are not to be introduced to spill areas and drainage conveyance systems.
b. Disinfect all areas where people can be exposed to sewage. Use the Street Bleaching S.O.P. attached to this plan.
c. Thoroughly wash-down the area. Spilled sewage and wash- down water shall be vacuumed-up and disposed of in the sanitary sewer.
d. Remove sandbags, plugs, traffic control equipment, etc.
9. Inspect the next manhole downstream to ensure that the blockage has not reoccurred.
10. Estimation of Spill Volume – The volume of the spill (in gallons) shall be estimated as soon as possible, so that spill notification procedures can be initiated.

4 Hazardous Material Response
4.1 Handling Suspected Hazardous Materials When
Responding to a sewer Spill
Upon arrival at the scene of a sewer spill, should a suspicious substance (e.g., oil sheen, discoloration) be found on the ground surface, or should a suspicious odor (e.g., gasoline) not common to the sewer system be detected, the sewer investigator or response crew shall immediately contact the supervisor for guidance before taking further action.
Should the supervisor determine the need to alert the hazardous material response team, the sewer investigator or crew shall await the arrival of the Fire Department for assistance. The crew may attempt to contain and abate the spill if safe and if the substance is known but must observe caution until assistance arrives. Proper personal protective equipment must be used.
Upon arrival of the Fire Department, the sewer crew will take direction from the Fire Department Representative with the lead authority. When determined safe and appropriate, the sewer investigator and crew shall proceed under this SERP with the containment, clean-up activities and correction.
4.2 Handling Suspected Hazardous Waste Spills
Encountered During Other Field Work
Background: Occasionally Public Works Staff are asked to assist with clean- up of various spills of liquid materials on City streets or elsewhere within the public right of way. Materials most often encountered include spilled paint, slurry from concrete washout bins at construction sites, lubricating oil or hydraulic fluid from vehicles, and infrequently spills of fuels, gasoline, and diesel.
General Precautions: Public Works Staff will typically rely on the vehicle driver’s knowledge of what the material is and handle the materials appropriately. Without knowledge of what the material is staff will assume the materials are hazardous and secure the area pending i dentification via testing for hazardous waste characteristics.
Public Works Staff will not get involved with the clean- up of any unknown substance and those known to be hazardous, such as gasoline, will be referred to hazmat trained personnel at the Glendale Fire Department.
Recovery: Typically, granular absorbents are used to soak -up as much of the liquid as possible and they are manually recovered by crews with push brooms. Used absorbents that are lightly soaked will be recovered and used again.
