Element 1 – Goals

City of Alameda Sewer System Management Plan, July 2025 1

1.0: Element 1 – Goals

1.1: SWB Requirements:

The goal of the Sewer System Management Plan ( SSMP) is to provide a plan and schedule to:
(1) properly manage, operate, and maintain all parts of the Enrollee’s sanitary sewer system(s), (2) reduce and prevent spills, and (3) contain and mitigate spills that do occur.

The Plan must include a narrative Introduction section that discusses the following items:
a. Regulatory Context
b. Sewer System Management Plan Update Schedule
c. Sewer System Asset Overview

1.2: Regulatory Context
This Sewer System Management Plan ( SSMP) describes the City of Alameda’s (City’s) wastewater collection system management activities . The purpose of these activities is to:

1. Maintain and improve the condition of the collection system infrastructure,

2. Control infiltration/inflow (I/I) and provide appropriate sewer capacity, and to

3. Minimize the number and impact of sanitary sewer spills that occur.

The State Water Resources Control Board (SW RCB) has previously issued statewide waste discharge requirements for sanitary sewer systems which include requirements for development of an SSMP . The State Water Board requirements were outlined in Order No. 2006-0003-DWQ, Statewide General Waste Discharge Requirements for Sanitary Sewer Systems, dated May 2, 2006 (WDR) and the Monitoring and Reporting Plan (MRP) WQ 2013-0058-Exec. These two SW RCB requirements were replaced on December 6, 2022, by SWRCB Order WQ 2022 -0103-DWQ Statewide Waste Discharge Requirements, General Order for Sanitary Sewer Systems, which became effective for all enrolled agencies on June 5, 2023.

Wastewater generated in the City’s collection system is conveyed to the EBMUD interceptor system, and is treated at EBMUD’s Main Wastewater Treatment Plant (MWWTP) (WDID 2 19014001) located near the eastern terminus of the San Francisco -Oakland Bay Bridge.

EBMUD also receives flows from six other “Satellite” collection system agencies: the citi es of Albany, Berkeley, Emeryville, Oakland, and Piedmont, and the Stege Sanitary District.

The Regional Water Board first issued an NPDES permit to EBMUD in 1976 for the wet weather discharges from EBMUD’s interceptors. This permit required EBMUD to eliminate the discharge of untreated overflows from its interceptors and to protect water quality in San Francisco Bay. The Regional Water Board issued similar permits in 1976 to members of the East Bay Communities, including the City of Alameda’s NPDES NO. CA0038474.

Element 1 – Goals

City of Alameda Sewer System Management Plan, July 2025 2

The Regional Water Board has reissued the NPDES permits every 5 years with the most recent renewal in 2025. The City’s permit can be located here: https://alamedaca.gov/public - works/public-works-key-documents.

During the 1980s, EBMUD and the seven Satellite agencies conducted studies to address the problem of overflows and bypasses of untreated wastewater that occurred during large wet weather events due to excessive infiltration and inflow (I/I) into the collection systems. These studies resulted in a long -term program of construction of collection system relief sewers and sewer rehabilitation (called the East Bay I/I Correction Program), and construction by EBMUD of improvements at the MWWTP as well as three ne w remote Wet Weather Facilities (WWFs) designed to store, provide primary -level treatment, and discharge flows that exceeded the capacity of its interceptor system during wet weather.

Over a period of 20 years, separated into multiple phases, the City installed relief lines, as well as removed and replaced sewer mains, manholes and lower laterals in targeted areas identified as being cost-effective for rehabilitation to reduce I/I. In addition, the City has carried out cyclic sewer rehabilitation projects on lines identified by the Maintenance Division as significantly deficient. Through the I/I Correction and Cyclic Sewer Rehabilitation programs, the City has rehabilitated or replaced about 27 miles of its gravity sewers and associated lower laterals (over 20 percent of the system) since 1987. Since 1988, the City has also implemented a private sewer lateral (PSL) certification program requiring the testing and/or repair or replacement of private (upper) sewer laterals at the time of property transfer.

On January 1, 2015, the City joined the regional Private Sewer Lateral program implemented by EBMUD, per Consent Decree requirement.

In 2009, the U.S Environmental Protection Agency (EPA), State Water Resources Control Board (SWRCB), and the San Francisco Bay Regional Water Quality Control Board (RWQCB) prohibited future discharges from the WWFs, and entered into a legal settlement with EBMUD to establish programs focused on reducing wet weather flows. Shortly thereafter, the EPA issued Findings of Violation and Orders for Compliance, also called Administrative Orders (AOs), to each of the seven EBMUD Satellite agencies requiring the development of specific plans and programs to reduce spills and control wet weather I/I into the collection systems. The AOs were subsequently replaced in 2011 by a Stipulated Order for Preliminary Relief (SO) with the EPA, SWRCB, and RWQCB. As required by the SO, the City has prepared various plans and reports related to the management, operation, and maintenance of its sewer system, including a n Asset Management Implementation Plan (AMIP), Inflow Identification and Elimination Plan, Subbasin Flow Monitoring and I/I Assessment Plan and Report, Pump Station Prioritization and Renovation Plans, as well as annual progress reports. The programs and practices described in those plans and reports have been incorporated into the relevant sections of this SSMP.

The seven Satellites and EBMUD entered into a Consent Decree with EPA, the SWRCB, and the RWQCB (Case Nos. C09 -00186-RS and C09-05684-RS) with the San Francisco Bay Element 1 – Goals

1.3: Sewer System Management Plan Internal Audits and Update Schedule The reissued WDR for sanitary sewers has been revised and defined new requirements for the auditing and updating of the Enrollee’s SSMP including the preparation of internal audits of the SSMP. Audits must be completed, and an Internal Audit Report prepared covering a three- year period ending August 2, 2024 . The Audit Report must then be completed, certified, and uploaded to the CIWQS system no later than February 2, 2025 . Upon completion of the audit , the City must update the Plan along with readoption by the City Council no later than August 2, 2025.

The next three-year audit period covers the period from August 3, 2024, thru August 2, 202 7.

The Internal Audit R eport must be completed, certified, and uploaded to CIWQS no later than February 2, 202 8. Thereafter, the internal audits shall be competed every three years on the same schedule. The first SSMP revision under the reissued WDR shall be publicly considered and approved by the City Council and uploaded and LRO certified to CIWQS no later than August 2, 2025. Thereafter , the updates must be complete d every six years from August 2, 2025. Failure by the City in complying with the new audit schedules requires the City to update the CIWQS system, notify the RWQCB with a justification for the failure to conduct the timely audit and a schedule for the completion of the audit . This does not change the required audit schedules for the future.

1.4: Sewer System Asset Overview
The City’s collection system includes approximately 1 38 miles of City-owned sanitary sewers, 46 sewage pump stations , and 6 miles of force mains, approximately 3,129 manholes and other sewer structures.

The City has a service area of 22.7 square miles and a service population of 80,000. The percentage of service connection customer classes are stated in Table 1 – 1 below. The information in Table 1 – 1 is from the City of Alameda Sewer Rate Study, Final R eport February 2025.

City of Alameda Sewer System Management Plan, July 2025 4

The original sewers in Alameda were primarily terra cotta pipe and were installed between 1890 and 1920. The sewers constructed after 1920 can be divided into three major groups based on the date of construction: those built prior to 1950; between 1950 and 1970; and 1970 to the present.

In Alameda, the property owner owns the entire service lateral from the building to the connection to the City’s sewer main; however, the City takes responsibility for maintenance and replacement of the lower portion of the lateral - owner operated laterals . Lower laterals are rehabilitated when the public sewer main to which it is connected to is rehabilitated, or if the lower lateral fails, whichever occurs first. The upper lateral remains the responsibility of the private property owner for operations, m aintenance and repair , and replacement. The City participates with the other agencies tributary to EBMUD, in the lateral replacement program .

This requires testing and possible repair or replacement of the upper lateral at the time of sale of the property.

This SSMP incorporates the sewer system programs and practices that are required as part of the Consent Decree and comply with the reissued WDR .

The following tables provide information on the sewer program assets under management by the City’s Department of Public Works Staff.

Element 4 – Operations and Maintenance Program

City of Alameda Sewer System Management Plan, July 2025 20

4.0: Element 4 – Operations and Maintenance Program
The Sewer System Management Plan ( SSMP) must include the items listed below that are appropriate and applicable to the Enrollee’s system:
a. Updated map of the sanitary sewer system
b. Preventative Operations and Maintenance
c. Training
d. Equipment Inventory

4.1: Collection System Map
The City maintains a set of sanitary sewer collection maps that contain information about the sewer, manhole, and pump station locations, pipe sizes, rim and flow line elevations, and references to construction drawings. The sewer map books are periodically published from the data contained in the City's Geographical Information System (GIS). The GIS (spatial and attribute data) is updated, as field edits are identified and/or following capital improvement projects. The GIS mapping is used for hydraulic mod eling and is integrated (ESRI SDE) with the City's maintenance management system, Lucity.

The City also maintains storm drain maps that contain GIS data and map books similar to the sanitary sewer asset information . The maps show the location of storm sewers and catch basins, pipe diameters and materials, manhole rim and flow line elevations, and flow directions. These systems can be overlaid in the GIS.

Field crews primarily use the GIS and Lucity available on their phones and/or Surface Tablets to locate assets .

4.2: Preventative Operations and Maintenance Program
The City implements a preventive maintenance program where all sewer mains are cleaned on a schedule ranging from a 90 -day to 10-year return frequency. A line's cleaning interval is based on its maintenance history, results of TV inspection, proximity to environmentally sensitive areas as well as other factors. This approach is intended to minimize the occurrence of repeat blockages and/or spills from sewer line segments. Line segments that are on a 90 - day return frequency are part of the "hot spot" cleanin g program. All other sewer line segments are on a condition -based return frequency with no return frequency to exceed 5 years for non-grid sewers and 10 years for grid sewers.

4.2.1: “Hot Spot” Program
Sewer mains and lower laterals with previous repeat spills and/or that are identified by maintenance staff as having recurring maintenance issues (e.g., roots, grease, or debris accumulation) are defined as “hot spots.” Sewer main hot spots are cleaned on a 90-day or 6- month schedule. Lower lateral hotspots are either cleaned on a 6 month schedule or have Element 4 – Operations and Maintenance Program

City of Alameda Sewer System Management Plan, July 2025 21

chemical root control applied every 9 or 12 months. The majority of locations part of the hotspot program are areas of known grease and/or root intrusion. A pipe segment can be removed from the hot spot list if repair or replacement work resolved the maint enance issues or if the maintenance issue is not present for three consecutive cleanings.

Pipe segments on the hot spot list are managed in Lucity. An attribute of each pipe segment is the return frequency for cleaning or root control. Staff can add or remove lines from the hot spot list by adjusting the applicable attribute .

4.2.2: System-Wide Routine Cleaning
Sewer pipelines not assigned an aggressive preventive maintenance frequency are cleaned as part of a system -wide (routine) preventive maintenance program. The gravity sewer mains in the City’s collection system are classified into two basic types: “grid” a nd “non-grid”. The sewers in the grid system are characterized by having multiple pathways for flow should a temporary pipe blockage and flow backup occur. This allows the flow to be bypassed to another, non-obstructed sewer main and be conveyed downstream in another direction, thereby preventing a sanitary sewer overflow. Over 60 percent of the gravity sewers in the main Alameda collection system are part of the grid system. Each pipe is flagged as “grid” or “non-grid” in the City’s GIS based on the config uration of the surrounding system.

The Consent Decree requires the City to complete cleaning of all pipes in the system (except for the Alameda Point system) by or before June 30, 2019. Thereafter, the City will clean all non-grid sewer mains at least once every five years and all grid sewer mains at l east once every ten years. Mains that are greater than 15 inches in diameter may be cleaned based on condition assessment, which shall, at a minimum, take into consideration any information concerning the accumulation of fats, oil and grease, sediment, and debris derived from CCTV inspection or cleaning history.

In 2016, the City finished cleaning and filming all accessible pipes, to have the necessary condition data to develop the City's Sewer Master Plan, which contains a 20 Year Sewer Rehabilitation program. This cleaning and inspection work was performed by a contractor with QA/QC performed by City staff. The date of last cleaning and inspection is stored in Lucity for each pipe segment with an assigned return frequency, which will generate a work order when the next cleaning or inspection activity is due.

4.2.3: Pump Station Preventative Maintenance
All 46 pump stations in the City are monitored 24 hours/7 days per week using SCADA technology. Each of the City’s pump stations is inspected and cleaned once per month. Lucity issues a monthly work order with the Monthly Pump Station Checklist . Any issue identified during the inspection requiring repair or other maintenance action is recorded in Lucity with applicable follow up work orders generated. Small issues are addressed immediately (the same day). Standby generators are also inspected monthly and ru n per manufacturer specifications.

Element 4 – Operations and Maintenance Program

City of Alameda Sewer System Management Plan, July 2025 22

4.2.4: Pump Station Force Mains
The City has about 5 miles of force mains ranging in size from 4 to 16 inches and in length from approximately 25 to over 3,300 feet, constructed of various types of pipe materials. The condition of the force mains is largely unknown; however, in 2015, the City started to replace force mains when pump stations are renovated. Since that time, 10 force mains (approximately 1,600 ft) were replaced with C900 restrained joints force mains. In addition, the Park/Otis force main was redesigned allowing for the abandonment of 3,248 feet of 8” asbestos concrete pipe. The new force main is 400 feet in length with C900 restrained joint. The City is currently working to develop and implement a force main condition assessment program for those force mains not scheduled for replacement in the near future. The force mains will be prioritized, and assessment methods tailored to each pipe based on age, material, size (or flow), location, and length, and whether or not the associated pump station has a high-level gravity pipeline bypass. Based on the results of the assessments, potential improvements to address identified force main condition deficiencies should be incorporated into the sewer system CIP.

4.2.5: Manhole Inspections
The City inspects manholes at the time of the cleaning of the pipe. These ins pections identify any issues or problems found in the manhole. The inspections do not use any defined standards for the conditions or issues found in the manholes. The condition from the visual inspection is input to Lucity and/or work orders are prepared and issued to repair any issue identified from the inspection.

4.2.6: Root Control
The City uses chemical root control on pipes identified to have root intrusion via CCTV inspection. Pipes treated are kept on a two -year treatment schedule until the pipe is replaced or otherwise repaired in a manner that prevents future root intrusion. Pi pe segments that are on the root foaming list are managed in Lucity. An attribute of pipe segments is Yes/No for the Root Control program. Those marked Yes have a Date Last Treated and Date Next Due for root foaming. Once a year, the PW Supervisor or Direc tor will query those pipes due for root control and prepare a work request for the root foaming contractor.

4.2.7: Non-Routine Maintenance
Non-routine maintenance activities include investigation and response to any reports or complaints regarding a sewer overflow or backup; missing, shifted, or noisy manhole covers; pump station malfunction; unexpected sewer odor, etc. Sewer complaints recei ved by the Public Works Department are entered into SeeClickFix, if the report is taken by administrative staff, or directly in Lucity if report is taken by sewer staff . SeeClickFix integrates with Lucity .

The reports are investigated, and appropriate acti ons are taken to resolve the source of the problem.

Element 4 – Operations and Maintenance Program

City of Alameda Sewer System Management Plan, July 2025 23

4.3: Training
The City's training activities fall into two categories, safety and job skills. The two are closely related insofar as safety is of prime consideration in performance of any job activity. Safety training is conducted by City staff or outside consultants in the areas listed below. One or more topics are covered during monthly training sessions. • Chemical Hygiene
• CPR / First Aid
• Driver Training
• Electrical lockout/tagout
• Emergency Response
• Fire Prevention/Fire Extinguishers
• Hearing Protection
• Forklift
• Hazard Communication
• Heat Stress
• Respiratory Protection
• Wastewater Pathogens
• Confined Space
Job skills training involves annual Spill Emergency Response Plan training, including methods to collect the information required for notification and reporting of spills under Order 2022-1030-DWQ, field exercises and volume estimation. All designated officials (LROs and DSs) receive regular training on the CIWQS system. Annual training also includes water quality monitoring. Specialized off -site training for specific job skills include National Association of Sewer Service Companies (NAS SCO) Pipeline Assessment Certification Program (PACP) train ing and CWEA conferences and other events. Each employee has a file which documents training received.

The City designated LROs and DSs receive regular training on the State CIWQS system. All training is individually tracked by employee for all training provided from attendee sign -in sheets.

4.4: Contingency Equipment and Replacement Inventories
Equipment, tools, and material for the collection system are maintained at the Maintenance Service Center located at 1616 Fortmann Way and the Pump Storage House at 950 West Ranger Avenue, and are accessible to the crews. The City keeps two emergency bypas s pumps Element 4 – Operations and Maintenance Program

5.0: Element 5 – Design and Construction Standards
The Plan must include the following items as appropriate and applicable to the Enrollee’s system:
a. Updated design criteria, and construction standards and specifications, for the construction, installation, repair, and rehabilitation of existing and proposed system infrastructure components, including but not limited to pipelines, pump stations, and other system appurtenances.
b. Procedures, and standards for the inspection and testing of newly constructed, newly installed, repaired, and rehabilitated system pipelines, pumps, and other equipment and appurtenances.

5.1: Standard Specification for Sewer System Facilities The City’s standards pertaining to the design, construction, inspection, and testing of gravity sewer systems, sewer force mains, and other facilities to be operated and maintained by the City are contained in the Regional Standards for Sanitary Sewer Syst em Installation, Rehabilitation and Repair, June 30, 2021 (revised), the California Plumbing Code, the California Department of Transportation Standard Specifications , and project-specific specifications for cyclic sewer replacement and pump station upgra de projects. The Regional Standards were developed per Consent Decree requirement and submitted to the Environmental Protection Agency. The City’s sewer design standards are required for both new installation and replacement facilities.

The City participates in the Regional Private Sewer Lateral Program, implemented by EBMUD. The program requires that private laterals be repaired or replaced as necessary, and pass an air or water verification test per the testing standards contained here:
http://www.eastbaypsl.com/eastbaypsl/doc/PSLContractorGuidelines.pdf

5.2: Standards for Inspection and Testing of New Facilities Sanitary sewer force mains require pressure testing for tightness after the completion of backfilling but prior to the request for final inspection . Sewer gravity lines are tested for water tightness, obstructions, and vertical deflection. Hydrostatic or air pressure methods, depending on the specific project, can be used to ensure test requirements are satisfied . Cases with geotechnical considerations require an internal television inspection to detect defects.

i. Clean the spill area and drainage conveyance system in a manner that does not inadvertently impact beneficial uses in the receiving waters; j. Implement technologies, practices, equipment, and interagency coordination to expedite spill containment and recovery;
k. Implement pre-planned coordination and collaboration with storm drain agencies and other utility agencies/departments prior, during, and after a spill event; l. Conduct post-spill assessments of spill response activities; m. Document and report spill events as required in this General Order; and n. Annually, review and assess effectiveness of the Spill Emergency Response Plan, and update the Plan as needed.

6.1: Existing Documentation
The City, pursuant to the reissued WDR, completed and updated the original Overflow Emergency Response Plan to a Spill Emergency Response Plan (SERP). The SERP includes Element 6 – Spill Emergency Response Plan

City of Alameda Sewer System Management Plan, July 2025 29

all new requirements, and the revised sampling and testing requirements formally contained in the City Water Quality Monitoring Plan (WQMP).

The City’s goals with respect to responding to sewer spills are:
• Respond quickly to minimize the volume of the spill;
• Contain the overflowed wastewater to the extent feasible; • Eliminate the cause of the spill;
• Minimize public contact with the overflowed wastewater; • Mitigate the impact of the spill; and
• Meet the regulatory reporting requirements.

6.2: Purpose
The purpose of the City of Alameda Spill Emergency Response Plan (SERP) is to support a prompt, orderly and effective response to spills (sanitary), reduce spill volumes, and collect information for prevention of future spills. A “spill” in this document is defined, by State Water Board Order No. WQ 2022 -0103-DWQ as a discharge of sewage from any portion of a sanitary sewer system due to a sanitary sewer system overflow, operational failure, and/or infrastructure failure.

The SERP provides guidelines for City personnel to follow in responding to, cleaning up, reporting, and properly documenting spills that may occur within the City’s service area. This SERP satisfies the State Water Board Order No. WQ 2022 -0103-DWQ, which require wastewater collection agencies to have a Spill Emergency Response Plan.

Additionally, the SERP outlines procedures for responding to sanitary sewer spill backups into structures as required by the City’s insurer. See definitions. “Backup” is a term typically used by insurers to describe property damage resulting from exposure and contact to untreated or partially treated sewage.

6.2.1: SSO Detection and Notification
The City can be notified of a sewer issue and/or spill in a variety of ways including a phone call from a member of the public, receipt of an alarm, and/or observation by City staff during the normal course of their work. The notification and response proc edure flow chart is shown in Figure 6 – 1.

Element 6 – Spill Emergency Response Plan

City of Alameda Sewer System Management Plan, July 2025 30

Figure 6 – 1: Notification and Response Procedure Flow Chart

6.2.2: Public Observation
Public observation is the most common way that the City is notified of blockages and spills.

Contact information for reporting spills and backups is on the City’s website:
www.alamedca.gov and messaged though Alameda See ClickFix, a mobile service request

Element 6 – Spill Emergency Response Plan

City of Alameda Sewer System Management Plan, July 2025 31

platform. The direct line to Public Works is (510) 747 -7930. If the public contacts local police, fire, or other city department, calls are forwarded to the Public Works Department during business hours and to on call Public Works staff after hours. A summary of the notification and response process is shown in Figure 6 – 1.

6.2.3: Normal Work Hours
Public Works normal working hours are Monday through Friday, 8:00 a.m. to 6:00 p.m., except holidays. When a report of a spill or backup is made during normal work hours, Public Works administrative staff receive the call, take information from the caller, and dispatch the appropriate staff.

The information regarding the service call is documented on a “Receiving a Sewer Service Call Report”, which is then scanned and uploaded to SeeClickFix, the City’s customer relations manager. This information is then available to responding staff and ulti mately is stored in Lucity as the spill documentation file.

6.2.4: After Work Hours
If a call comes into Public Works outside business hours, they are directed to press a number to connect to Police Dispatch in case of an emergency. The Public can also contact Police Dispatch directly at (510) 337 -8340. Police Dispatch contacts the on-call staff Public Works staff member. The on-call staff member carries a cell phone and pager. The cell phone and pager also receives alarm signals from the pump station SCADA monitoring system.

If the on-call staff member does not respond, Police Dispatch has a backup list of phone numbers, including the Sewer Shop Foreperson and Public Works Supervisor. The Police Dispatcher continues to call Public Works staff until one can be reached to respon d to the call.

Police Dispatch communicates the information received to the respondent staff member.

After hours response information is entered directly into Lucity, the City’s maintenance management system, by the on-call staff member.

6.2.5: City Staff Observation
Maintenance staff may observe sewer system emergencies while performing their routine activities. Maintenance Staff are instructed to report problems to the general Public Works Department number so administrative staff can receive the call and follow the procedures to document and dispatch staff for the incident . Any other City staff that observe a sewer issue are instructed to forward any reports of sewer problems to the Public Works Department.

6.2.6: Alarms
Pump station alarms are transmitted via SCADA to the Maintenance Service Center during working hours and the on -call staff member after hours.

Element 6 – Spill Emergency Response Plan

City of Alameda Sewer System Management Plan, July 2025 32

6.3: Spill Notification, Reporting, Monitoring and Record Keeping All spills caused in the public system should be thoroughly responded to with documentation maintained in a unique incident file. Each incident should have the Spill File Incident Checklist Form completed and associated materials stored in that file. Notification, reporting, monitoring and record keeping provisions follow in the below sections.

6.3.1: Spill Categories
The California State Water Resources Control Board (SWRCB) has established guidelines for classifying and reporting spills in the WDR . Notification, reporting and monitoring requirements may vary based on the category of spill. The spill categories defined in the WDR are included in Table 6 – 1.

Table 6 – 1: Spill Categories and Definitions
Categories Category Definitions
Category 1
A Category 1 spill of any volume of sewage from or caused by a sanitary sewer system regulated under WDR 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.

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.

Element 6 – Spill Emergency Response Plan

City of Alameda Sewer System Management Plan, July 2025 33

Categories Category Definitions
Private Lateral
Sewage Discharge
(PLSD)*
Discharges of untreated or partially treated wastewater resulting from blockages or other problems within a privately owned sewer lateral connected to the enrollee’s sanitary sewer system or from other private sewer assets. PLSDs that the enrollee becomes aware of may be voluntarily reported to the CIWQS Online spill Database.
* In the City of Alameda, the property owns the entire lateral (upper and lower); however, the City has maintenance responsibility for the lower lateral. Therefore, only discharges that are caused by a failure/blockage from the upper are considered Private L ateral Sewage Discharges.

6.3.2: Requirements by Category
Table 6 – 2 contains a summary of the regulatory notification, reporting, monitoring and record keeping requirements by category. California Integrated Water Quality Information System, http://ciwqs.waterboards.ca.gov, should be used for reporting spill information to the SWRCB.

If a spill reaches one of the lagoon systems in the City or the Robert Crown State Beach shoreline:
• South Shore Lagoon System : In the event any spill enters the South Shore Lagoon, the Public Works Supervisor will notify the Alameda West Homeowners Association (HOA) President and the East Bay Regional Park District. Contact information is included in Appendix B of this SERP.
• Bay Farm Island Lagoon System : In the event any spill enters one of the Bay Farm Island Lagoons, the Public Works Supervisor will notify Harbor Bay Security. The Harbor Bay Security number is (510) 865 -0417.

In addition, internal notification procedures – The Maintenance Service Center (working hours) or on-call staff (after hours) will immediately notify the Sewer Shop Foreperson and Public Works Supervisor of any Category spill. The Public Works Supervisor will notify the Public Works Director .

6.4: Training
This section provides information on the training that is required to support this Spill Emergency Response Plan.

6.5: Initial and Annual Refresher Training
All City personnel who may have a role in responding to, reporting, and/or mitigating a sewer system overflow should receive training on the contents of this SERP. All new employees should receive training before they are placed in a position where they ma y have to respond.

Current employees should receive annual refresher training on this plan and the procedures to be followed.

6.6: Spill Response Drills
Periodic training drills should be held to ensure that employees are up -to-date on the procedures, the equipment is in working order, and the required materials are readily available. The training drills should cover scenarios typically observed during sewer -related emergencies (e.g., mainline blockage, mainline failure, force main failure, pump station failure, and lateral blockage). The results and the observations during the drills should be recorded and action items should be tracked to ensure completion.

6.7: Tailgate Sessions
The Maintenance Service Center tailgate meetings that cover a variety of topics applicable to their responsibilities and safety requirements. Spill emergency response is a topic at these tailgate sessions on a routine basis.

6.8: Spill Training Record Keeping
Records should be kept of all training that is provided in support of this plan. The records for all scheduled training courses and for each overflow emergency response training event and should include date, time, place, content, name of trainer(s), and n ames of attendees.

City of Alameda Sewer System Management Plan, July 2025 38

6.9: Contractors Working on City Sewer Facilities
Any contractors that work or otherwise utilize the sewer system are required to comply with all legal requirements associated with SSO responses, be provided a copy of the City’s SERP and have knowledge of the City’s response procedures and requirements.

6.10: Policy
The City’s employees are required to report all spills from agency owned sewer mains and publicly owned laterals found and to take the appropriate action to secure the spill area, properly report to the appropriate regulatory agencies, relieve the cause of the spill, and ensure that the affected area is cleaned as soon as possible to minimize health hazards to the public and protect the environment. The City’s goal is to respond to sewer system spills as soon as possible following notification. The City wil l follow reporting procedures regarding sewer spills as set forth by the San Francisco Regional Water Quality Control Board and the State Water Board Order No. WQ 2022 -0103-DWQ (WDR).

The cover of the Spill Emergency Response Plan document is included in the SSMP Appendix D that contains all documents used to properly document the City response activities to all spill events.

Element 7 – Sewer Pipe Blockage Control Program

City of Alameda Sewer System Management Plan, July 2025 39

7.0: Element 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:
a. An implementation plan and schedule for a public education and outreach program that promotes proper disposal of pipe -blocking substances;
b. 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;
c. The legal authority to prohibit discharges to the system and identify measures to prevent spills and blockages;
d. 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; e. 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;
f. An identification of sanitary sewer system sections subject to fats, oils, and grease blockages and establishment of a cleaning schedule for each section; and g. Implementation of source control measures for all sources of fats, oils, and grease reaching the sanitary sewer system for each section identified above.

7.1: Public Education and Outreach Program
Data on spills and causes were analyzed to define the nature and extent of FOG problems in the City’s sewer system. The City has reported 36 spills during the past five years (as of July 2024), 20 of which were caused by FOG, or an average of about four FOG-related spill per year.

The City’s preventive maintenance efforts combined with the EBMUD FOG Source Control Programs appear to be effective in minimizing the problems associated with commercial FOG sources; however, FOG discharges do cause increased maintenance in sewer mainlines , lower laterals and at City pump stations. City staff intends to pursue Council approval of a FOG ordinance, similar to other East Bay jurisdictions, with better definition around prohibited FOG discharges, Food Service Establishment requirements for the installation and Element 7 – Sewer Pipe Blockage Control Program

City of Alameda Sewer System Management Plan, July 2025 40

maintenance of grease control devices, and enforcement . The City will continue to contract with EBMUD for FOG Source Control Program services.

EBMUD’s services include targeted FOG hot spot investigations (as reported by the City), food service establishment (FSE) and grease interceptor inspections, and public outreach and education. EBMUD also maintains a FOG control database to manage informati on about FSEs, inspections, FOG hotspots, and enforcement status. A quarterly report is prepared for each agency.

The City’s building plan check records for FSEs are provided to EBMUD on a regular basis so that EBMUD has a record of all such establishments within the City. FSEs must have grease interceptors per the California Plumbing Code (CPC).

EBMUD prepares materials to be used as the basis for a focused public education/outreach program. EBMUD and the City provide public education/outreach materials at public events and to commercial and residential sources that are tributary to sewers that ex perience FOG- related stoppages and spills.

7.2: Plan and Schedule for Disposal of Pipe-Blocking Substances A list of grease haulers approved by EBMUD is included as Supplement 7 – A. There is adequate disposal capacity for FOG from commercial sources within the City’s service area.

7.3: Legal Authority
The City’s legal authorities to control the discharge of FOG to its sanitary sewer system are described in Chapter 3, Legal Authority; however, staff intends to pursue Council approval of a FOG Ordinance, as described in Section 8.2. EBMUD currently issue two Notice of Violations, as applicable, for non -compliance identified during FSE inspections. Enforcement action beyond the two notices is the City’s responsibility.

7.4: Identification and Sewer Cleaning
The City’s preventive maintenance program is focused on the problematic sewer line segments. Historically, FOG hot spots were located in the business districts with restaurant establishments, namely Park Street, Webster Street, and the Town Centre Shopping Center.

The City uses the results from sewer cleaning operations to revise se wer cleaning frequencies as required to address FOG issues. City staff provides the EBMUD FOG Source Control Program staff with timely notice when gravity sewers experience FOG -related blockages or spills.

7.5: Authority for Grease Control Devices, Inspections and Enforcement The City Building Department is responsible for the determination of the need for grease control devices as part of the application of new or modified food service establishments.

They also are responsible for the inspection and approval of the final construction at the s ite.

Once installation is completed and approved by the City, EBMUD is then notified and Element 7 – Sewer Pipe Blockage Control Program

City of Alameda Sewer System Management Plan, July 2025 41

conducts all future inspections and preliminary enforcement activities. The City is ultimately responsible for any legal enforcement requirements with the assistance of EBMUD.

Element 8 – System Evaluation and Capacity Assurance Plan

City of Alameda Sewer System Management Plan, July 2025 42

8.0: Element 8 – System Evaluation and Capacity Assurance Plan
The SSMP must include procedures and activities for:
a. Routine evaluation and assessment of system conditions; b. Capacity assessment and design criteria;
c. Prioritization of corrective actions; and
d. A capital improvement plan.

8.1: Routine Evaluation and Assessment of System Conditions

8.1.1: Pipeline Condition Assessment
CCTV inspection is the basic method used by the City to gather the data required to assess sewer condition. The City’s CCTV inspection program was initiated in 2009 and has been ongoing since. Both contract resources and in -house staff perform CCTV inspect ions of the system. The inspections (both by contractor and City) include digital capture of CCTV data, video, and still images using Granite.NET sewer inspection data management software .

The City uses the Pipeline Assessment and Certification Program (PACP) system developed by the National Association of Sewer Service Companies (NASSCO), which has become the standard of the industry for sewer condition assessment . PACP utilizes standard observation codes to describe different types of structural and maintenance -related defects and construction features, with defect grades assigned to each defect based on its type and severity.

Under the PACP standard, all structural defects are assigned a Structural Grade of 1 to 5, with Grade 5 representing severe defects and Grade 1 representing minor defects. (Maintenance defects are assigned similar O&M grades.) The grades for individual def ects observed on a manhole-to-manhole pipe segment can be combined in various ways to determine an overall structural condition rating for the pipe. The PACP manual suggests several approaches for this purpose, including summing the grades of all defects o r averaging the grades . While such approaches may be useful for screening pipes in terms of overall condition, they may not be particularly useful for prioritizing pipe replacement. What is most important in such decisions is the presence of major defects and the number of such d efects. For example, a single Grade 5 defect in a pipe may require immediate action, while five Grade 1 defects would not, even though they both have a PACP overall segment grade score of 5.

8.1.2: Manhole Assessments
The City regularly assesses manholes along with the cleaning operation. Work orders are issued for staff to handle minor repairs or if the repairs is more complicated, private contractors would be hired to accomplish the repair.

Element 8 – System Evaluation and Capacity Assurance Plan

City of Alameda Sewer System Management Plan, July 2025 43

8.1.3: Lift Station Assessment
The City has conducted extensive assessments of its sewer pump stations as part of separate studies. Information on estimated peak wet weather flows from hydraulic modeling have been considered in developing recommendations for pump station improvements, a s well as other considerations including safety, reliability, structural condition, and ease of operation and maintenance. The City’s 2012 Pump Station Renovation Plan developed a program for pump station improvements to be implemented . The pump station im provements varied by station but may include new pumps, conversion to submersible pumps, relocation, or re -building.

Standardization of pumps and equipment was also a major objective of the pump station renovations.

8.1.4: Force Mains, and Pressure Pipes
It is recommended that the City develop and implement a force main condition assessment program to address the condition of its sewer force mains . The force mains should be prioritized for assessment based on age, material, size (or flow), location, and length, and whether or not the associated pump stations also have high level bypass gravity pipelines.

Initially, the assessment could focus on the longest force mains (e.g., the seven that are over 1,000 feet in length) and the 15 force mains associated wit h pump stations that do not have gravity bypass lines.

Methods of inspection should be tailored to the pipe material, size and length, location and access, and other factors, but could include CCTV inspection (if possible), external corrosion investigations, or various pipe wall thickness and pipe leakage asse ssment methods. Based on the results of the assessments, potential improvements to address any identified force main condition deficiencies should be developed and incorporated into the sewer system CIP.

8.2: Capacity Assessment and Design Criteria

8.2.1: Hydraulic Analysis and Capacity Assurance
In May 2010, the City completed a Sanitary Sewer System Hydraulic Analysis study that included development of a dynamic hydraulic model of the collection system and use of the model to identify potential capacity deficiencies in the system. A model of the future Alameda Point sewer system was developed separately, as discussed later in this section. In 2015, the City updated the dynamic hydraulic model to incorporate new sewers and developments constructed since 2010 and additional flow data collected by EB MUD and the City since the original model was developed. Data from flow monitoring programs conducted by the City and by EBMUD during the 2009/10 and 2010/11 wet weather seasons were used to estimate the amount of I/I for various areas of the system and to confirm, through model calibration, that the hydraulic model reasonably simulates the actual performance of the system during both dry and wet weather conditions. The model was also expanded to include the proposed future sewer system in Alameda Point, as described below.

Element 8 – System Evaluation and Capacity Assurance Plan

City of Alameda Sewer System Management Plan, July 2025 44

The capacity of the system was assessed with respect to a design storm condition, defined as a design rainfall event falling under saturated soil conditions with the timing of the storm such that the peak I/I flows occur at about the same time as the peak diurnal base wastewater flow in most areas. The design rainfall is a 7 -hour historical storm (known as the “EBMUD design event”), which was defined for the 1980s I/I studies and has been used since that time by the Satellites and EBMUD for wet weather eval uations. The storm has an approximate rainfall return period of 5 years, but based on the assumed timing of the storm under design event conditions, it is generally thought to create a return period of peak wastewater flow that is greater (less frequent) t han the return period of the rainfall event.

The hydraulic model was run with the design event to identify areas of the sewer system that would not have adequate capacity to convey the peak wet weather flows generated by that event. Capacity was considered inadequate whenever the model predicted that the peak flows would result in surcharge (flow above the crown of sewer pipes) to within five to six feet of manhole rims.

The modeling indicated that overall, the Alameda system has adequate capacity to convey peak wet weather flows. Only two potential capacity deficiencies were identified, both located within and/or downstream of the Harbor Bay Business Park area. Proposed s ewer capacity improvements (pipe upsizing along Harbor Bay Parkway and Beach Road) were developed for these areas. The project along Harbor Bay Parkway is required to address a predicted existing capacity deficiency; the Beach Road project would only be re quired in the future when additional development in the Harbor Bay Business Park occurs. The City has experienced no capacity related overflows at either of these locations to date. The Hydraulic Analysis report recommends, and the City has , monitored these locations and will continue to do so before constructing improvements to confirm the capacity issues under peak wet weather flows.

The modeling also provided updated estimates of peak wet weather flows to the modeled system pump stations, which were compared to the existing and planned station firm capacities (firm capacity is the capacity of the pump station with the largest pump out of service). The City completed all pump station improvements identified in the Pump Station Renovation Program.

Note that climate change and predicted sea level rise may result in increased rainfall and higher groundwater levels in the system in the future. However, as the City continues to rehabilitate and replace sanitary sewers, and property owners replace their private service laterals, these changes are not expected to result in any further capacity issues in the Alameda sewer system.

Model results indicating peak I/I rates from different areas of the system were used as inputs to the pipe rating model, described previously in Section 4.4 .

Note that overflow events (SSOs) in the City’s sewer system have generally been associated with maintenance or construction related issues (e.g., blockages due to roots, debris, or Element 8 – System Evaluation and Capacity Assurance Plan

City of Alameda Sewer System Management Plan, July 2025 45

construction material or defects) rather than wet weather. As a result of the 1980s I/I and wet weather studies conducted by EBMUD and the Satellites, the City constructed a number of relief trunk sewers, completed sewer rehabilitation to reduce I/I the sy stem, and removed any wet weather bypasses that existed at the time. These efforts over the past 45 years have eliminated capacity -related overflows in the system. As indicated by the Hydraulic Analysis results, virtually no existing pipe capacity restrict ions remain in the system; and the City upgraded its pump stations where needed to provide adequate capacity for design peak wet weather flows.

A complete overview of the 2015 Hydraulic Analysis is contained in the City Sewer Master Plan, November 2015: https://www.alamedaca.gov/files/assets/public/v/1/publicworks/sewer - master-plan-final-novemeber-2015.pdf

8.2.2: Prioritization of Corrective Actions
The City’s 2015 Sewer Master Plan developed a customized Pipe Rating Model which assigns a risk score to each pipe based on likelihood and consequence of failure factors and provides a means of prioritizing pipes for rehabilitation and replacement. The Pipe Rating Model, described below, was the key tool used for project prioritization for this Sewer Master Plan for sewer renewal and replacement and capital planning program. The methodology embodied in the Pipe Rating Model is based on guidelines recommende d by the National Association of Clean Water Agencies (NACWA). The methodology involves quantifying and assessing the risks posed by the failure or inability of the sewer system to provide the level of service needed to meet the City’s sewer system managem ent goals. Using this approach, risk scores are calculated for each sewer pipe individually. Individual pipe scores can then be used to prioritize and group pipes into sewer rehabilitation and replacement projects.

The risk of asset failure is calculated by quantifying the likelihood of failure (LOF) and the consequence of failure (COF) of a sewer asset. The likelihood of failure is the possibility of asset failure and is synonymous with the “probability” of failure. The consequence of failure is defined as the impact on level of service resulting from asset failure. The risk equation is defined as follows:

Risk = [(Likelihood) x (Consequence)]
Likelihood of Failure
Four indicators of likelihood of failure were utilized in the Pipe Rating Model:
• Structural Condition: Structural condition was determined based CCTV inspection results, as stored in the Granite XP database. If CCTV inspection data did not exist for a pipe segment, then the likelihood of failure was estimated based on pipe segment age. Structural conditio n is a strong indicator of likelihood of failure and was heavily weighted.

Element 8 – System Evaluation and Capacity Assurance Plan

City of Alameda Sewer System Management Plan, July 2025 46

• Operations & Maintenance (O&M) Condition : The required frequency of sewer cleaning is an indicator of the likelihood of asset failure due to a maintenance -related issue that could lead to an SSO. In addition, pipes that have roots and grease are also indicators of structural integrity which coul d lead to eventual failure. Data from the City’s CCTV inspection program were used to quantify likelihood of failure due to maintenance condition. This likelihood of failure factor was given a lower weighting than other factors since, unlike structural, capacity and I/I issues, preventive maintenance cleaning can be performed to reduce the risk of SSOs due to recurring maintenance problems.
• Capacity Deficiency : This likelihood of failure factor is calculated from hydraulic modeling results. Sewers with insufficient capacity that are predicted to result in significant surcharge or potential overflows under a design event peak wet weather flow condition were cons idered to have a high likelihood of failure due to capacity deficiency.
• I/I Contribution : This factor is based on the relative impact of I/I in the City’s system on flows in the EBMUD interceptor system that contribute to discharges from EBMUD’s Wet Weather Facilities (WWFs). Basins contributing higher amounts of I/I (based on peak I/I flow p er foot of pipe) are assigned a higher I/I score and may be targeted for improvements to reduce flows to the EBMUD system.

Consequence of Failure
Consequence of failure is assessed by examining the impact on economic, social and environmental factors. This approach, often referred to as the Triple -Bottom-Line approach, involves identifying and quantifying suitable indicators that represent these core categories .

For this study, the following indicators were used to assess the Consequence of Failure:
• Flow Volume (Economic) : Larger sewer spills or failure of a sewer asset serving a large tributary area can have a significant impact on the cost of fixing the pipe and restoring damaged property and the surrounding area. The size of the sewer was chosen as an indicator of the p otential impact of large spills or failure of a major sewer asset.
• Community (Social) : Sewer failures can significantly impact commuters, commercial areas, public facilities, and the community in general. Location in major roads or commercial areas, or proximity to critical facilities such as emergency services, hospitals and schools were used as indicators of potential community impact. In addition, sewers located in easements (i.e., not in a public right -of-way) are considered to have a greater social impact, hence, were included as a community impact factor.

Element 8 – System Evaluation and Capacity Assurance Plan

City of Alameda Sewer System Management Plan, July 2025 47

• Environmental: Sewer overflows that reach surface waters can adversely impact water quality and the environment. Distance to surface water and storm drain inlets was used as an indicator of the potential environmental impact of a sewer spill.

Risk Score Calculations
The Pipe Rating Model utilizes data directly from GIS and Granite XP, and indirectly from the hydraulic model developed and used for the Master Plan, to compute LOF scores.

Structural and O&M conditions were derived from data from previous and recent CCTV inspection programs collated and managed through Granite XP. Community and environmental COF scores were derived from GIS mapping. The risk score calculations were processed using ArcGIS ModelBuilder tools, which combine a series of GIS processes to automate the risk analysis calculations.

The resulting ranking was then used to develop the capital improvement program schedule and availability of funding for the priority projects and to meet the required schedules for replacement in the City Consent decree. Based on the above program, by the end of 20 years the City will have rehabilitated or replaced over 75 percent of its gravity sewer system. The City may elect to modify the CIP schedule as needed to accommodate budget constraints and changes in project priorities as additional inspection d ata and other information are collected over time. Such information may include coordination with street paving or other infrastructure or utility projects; new or recurring maintenance problems in the system; or incorporate specific information provided b y EBMUD as to priority areas for focusing I/I reduction efforts.

8.2.3: Capital Improvement Program (CIP)
The City Engineering Division is responsible for the preparation, management, administration and construction of the long-term capital improvement program. The 2015 Sewer Master Plan developed a 20 year gravity pipeline rep lacement program based on the pipe rating model described above.

The sewer rehabilitation CIP was developed from the Sewer Master Plan based on the following three primary criteria:
• Meet the minimum annual sewer rehabilitation footage requirements of the Consent Decree.
• Maintain consistency with the City’s annual capital improvement budget based on the financial plan and sewer service charge schedule that has been adopted by the City Council.
• Prioritize sewers for rehabilitation based on risk scores as calculated by the Pipe Rating Model and other factors such as pipe material, pavement condition, and proximity.

Element 8 – System Evaluation and Capacity Assurance Plan

City of Alameda Sewer System Management Plan, July 2025 48

8.2.4: Biennial CIP Budget
The City Public Works Department is responsible for the preparation and approval of a biennial capital improvement program (CIP) for all city operations including the sanitary sewer program. The CIP is prepared using the Sewer Master Plan prioritization process and schedules developed therein. The adopted CIP was last approved in June 2023 for the period 2023-24 thru 2024-25. The next CIP is estimated to be considered by the City Council in June 2025.

8.2.5: Project Funding
The City generally relies on sewer service charges and sewer fund reserves to fund the biennial capital program work. The City last conducted a sewer rate study in 2025 to set rates for Fiscal Years 2025/26 through 2029/30 . A 3% annual increase over the 5 year rate period was determined optimal to:
• Fund sewer pipeline replacements and other capital improvements . • Maintain adequate operating and capital reserves .
• Meet or exceed debt coverage requirements .
• Mitigate impacts on the ratepayers .

8.2.6: Joint Coordination
The City staff from both Engineering and Operations Divisions regularly meet to discuss and develop the capital program and to review changes and funding required for any changes proposed in the Capital Budget.

9.1: Adaptive Management
The City regularly tracks and updates the performance results of the sanitary sewer program .

In addition, the SERP is also reviewed for effectiveness and any changes are made to assure proper and timely responses prior to the annual report certification requirement. The City also pursues and evaluates the SSMP Audit Report corrective actions to dete rmine when and how the program should be modified and changed. Finally, the sewer program uses the historical performance results, post spill assessments and ope ration and maintenance results during the development of the Annual Sewer Report to assess the need for further adaption of the program to reduce spills to Waters of the State and to review and consider implementing technology changes to further improve op erations of the program. All modification and changes to the SSMP are then included in the SSMP Change Log.

9.2: Effectiveness
The effectiveness of each SSMP element is measured through the use of selected performance indicators. These indicators are tracked and reported regularly and include the annual performance requirements in the SSMP for the Annual Report submitted to the CIWQS system. The results are used to evaluate the effectiveness of the overall sewer program comparing regular operations and maintenance results against the effectiveness of the spill response program protecting Waters of the State. Performance indicator results are incorporated into historical graphs displayed in Appendix E . Below are some of the indicators that the City will use as they evaluate the success of the maintenance program and adapt the sewer program in the future :
• Annual total number of spills
• Annual spills by spill category

• Net volume spill indices, gallons/1000 capita/year
• Annual linear feet of routine cleaning
• Annual linear feet of CCTV inspection performed
• Annual linear feet of chemical root control performed • Annual linear feet of gravity sewer rehabilitated or replaced

9.3: Updating Plan Procedures and Activities
Based on the above monitoring, performance criteria and historical graphs, the audit reports and any changes identified in the SSMP Change Log, the elements of the SSMP will be updated or modified, as appropriate during the six -year period. At a maximum, t he SSMP will be updated every six (6) years and include any significant program changes. In accordance with Subsection D.14 of the Order, the updated SSMP will be re -certified by the City Council and uploaded and certified by the City LRO into the CIWQS da tabase. All SSMP changes resulting from the adaptive management process and audits will be identified in detail in the SSMP Change Log between Council adoptions.

9.4: Identifying and Illustrating Trends
Performance indicator data are compiled from information regularly collected and maintained by the Public Works Supervisor. Current and readily available sources, which are described throughout this SSMP, include spill field report forms, CIWQS database reports, sewer system cleaning schedules, and FOG inspection reports. Historical graphs of spill and operational performance results are displayed in Appendix E.
