City of Culver City, California
Agenda Item Report
RECOMMENDATION:
Staff recommends the City Council adopt a Resolution approving the 2014 Update to
the City’s Sewer System Management Plan (SSMP) pursuant to State Water
Resources Control Board (SWRCB) Order No. 2006-0003-DWQ as revised by Order
No. WQ 2013-0058-EXEC.
BACKGROUND
On May 2, 2006 the SWRCB) adopted the Statewide General Waste Discharge
Requirement (WDR) and Monitoring and Reporting Program (MRP) to regulate
wastewater collection system management. The WDR applies to all public collection
system agencies in California that own or operate collection systems with more than
one mile of sewer lines that convey untreated wastewater to a publicly owned
treatment facility. One of the requirements of the WDR is that each covered agency
prepare, certify, and implement a SSMP. Staff prepared and the City Council
adopted the City’s SSMP on July 13, 2009 through adoption of Resolution 2009-
R055.
On July 26, 2013 the SWRCB’s Executive Director issued Order No. WQ 2013-
0058-EXEC which revised MRP requirements effective September 9, 2013. These
changes have been developed over the past three years with input from regulated
agencies and professional organizations and are based on six years of SWRCB
Enforcement Office field inspections of collection systems throughout the State.
Some of the changes in the MRP include:

Agenda Item Report
1. Reducing Sanitary Sewer Overflow (SSO) notification requirements to a single
call to the Office of Emergency Services for SSOs greater than 1000 gallons.
2. Requiring a new Water Quality Monitoring Plan and Technical Report for SSOs
greater than 50,000 gallons.
3. Streamlining the information that must be reported to the State SSO system for
small and medium SSOs.
4. Requiring enhanced recordkeeping for SSO events.
5. Requiring an agency to maintain an up-to-date list of Legally Responsible
Officials.
6. Eliminating the reporting requirement for SSOs on private sewer laterals.
7. Adding a 120-day time limit for amending and recertifying SSO reports.
Staff has ensured the City’s compliance with the new MRP requirements since the
September 9, 2013 effective date.
These new regulations required staff to make changes to the City’s July 2009 SSMP
to address the new MPR requirements. The WDR requires the City to certify that the
SSMP is in compliance with the WDR every five years or when significant updates to
the SSMP are made. The SSMP must be formally adopted by the City Council at a
public meeting to assure that the public has opportunity to comment. Previously, the
City designated the Public Works Director/City Engineer as Legally Responsible
Official(s) LRO(s) who must certify all information submitted in the SSO reporting
system.
DISCUSSION
The SSMP describes the City’s wastewater collection system management
activities. The purpose of the SSMP is to establish a formal program for
maintenance, rehabilitation, and operation of the City’s sanitary sewage collection
system. Effective management of a sanitary sewer collection system includes:
1. Maintaining or improving the condition of the collection system infrastructure to
provide reliable service.
2. Cost-effectively minimizing the infiltration/inflow (I/I) of groundwater and providing
adequate sewer capacity to accommodate additional flows during storm events.
3. Minimizing the frequency and impact of SSOs.
The required elements of the SSMP are as follows:
ELEMENT DESCRIPTION
1. SSMP Goals
2. Organization including SSO reporting and chain of command
3. Legal authority to operate the sewer system and to control discharges
4. Operation and Maintenance Program City of Culver City, California
Agenda Item Report
5. Design and Performance of the Sewer System
6. Overflow Emergency Response Plan
7. Fats Oils and Grease (FOG) Program
8. System Evaluation and Capacity Assurance Program.
9. Monitoring, Measurement and Program Modifications
10. SSMP Audits
11. Communication Program
The SSMP has been revised to address the requirements of the new order and to
address the City’s experience over the last five years. The City has made significant
progress in improving the reliability of the City’s sanitary sewer system by performing
closed circuit television (CCTV) inspections of sewer mains and repairing or lining
aging pipe segments. These actions reduce blockages and sewer spills and reduce
exfiltration of sewage into surrounding soils. The City has also been improving
sewage pump stations to provide operational redundancy to reduce the likelihood of
sewage spills. The City continues to pursue a project to eliminate four pump
stations south of Ballona Creek through the construction of a single state-of-the-art
pump station at Bankfield Avenue.
FISCAL ANALYSIS:
The City’s annual budget for operating and maintaining the sewer system is currently
$8.4 million, including $3.8 million paid to the City of Los Angeles to convey and
treat Culver City sewage at the Hyperion Sewage Treatment Plant. Approval and
adoption of the SSMP is a negligible expense; however, additional expenses may be
realized if deficiencies in the sewer infrastructure are revealed.

INTRODUCTION
On May 2, 2006 the State Water Resources Control Board (SWRCB) adopted a Statewide General Waste
Discharge Requirements and Monitoring and Reporting Program (WDRs) by issuing Order No. 2006-003
(Appendix A). The regulations in the Order were born out of growing concern about the water quality
impacts of Sanitary Sewer Overflows (SSOs), particularly those that cause beach closures or pose serious
health and safety or nuisance problems.
Two major components of the WDRs are the requirements that owners and operators of publicly owned
collection sewer systems a mile long or greater apply for coverage under the WDRs and that they
develop and implement a Sewer System Management Plan (SSMP). Culver City owns and operates
eighty five (85) miles of gravity and force main sewers and seven (7) pump stations and is therefore
subject to the WDRs.
This document is separated into eleven (11) chapters and organized to be closely in line with the
requirements contained and as they appear in the WDRs. Every section or subsection of each chapter
addresses one of the key elements of the SSMP guidelines of the WDRs.
This document has been prepared through a joint effort between City Maintenance, Engineering and
Environmental Programs staff. Current practices were evaluated and modified to achieve compliance
with the WDRs and to reduce or eliminate SSOs.
On September 9, 2013, SWRCB adopted Order No. WQ 2013-0058-EXEC amending the monitoring and
reporting procedures listed in the original Order (Amendments). The WDRs require that the SSMP be
updated and recertified a minimum of once every five (5) years. The City of Culver City’s original SSMP
was certified with the SWRCB on July 2009, and this SSMP dated June 2014 is the City’s update to its first
SSMP.
Sewer System Management Plan (SSMP)

1.0 GOALS
The goal of the SSMP is to provide a plan and schedule to properly manage, operate, and maintain all
parts of the sanitary sewer system. This will help reduce and prevent SSOs, as well as mitigate any
SSOs that do occur.
The goals of the City’s SSMP are to ensure that:
1. Culver City collection system facilities are properly operated, maintained, and managed to
minimize sanitary sewer overflows (SSOs) and their impacts on receiving waters and on public
health and safety;
2. When SSOs do occur, response measures are in place and that all feasible steps are taken to
mitigate their impacts to public health and the environment;
3. SSOs are promptly reported to the appropriate regulatory authorities and the public is
adequately notified within the required time frames; and
4. All SSOs events, system deficiencies and remedial actions taken are well documented;
5. To provide a safe working environment for City employees;
6. To provide City employees with the tools and training needed to perform their work effectively
and achieve the City’s goals.

3.0 LEGAL AUTHORITY
The Culver City City Council has the authority to make and enforce all rule and regulations necessary for
the cleaning, repair, construction, reconstruction, renewal, replacement, operation, and maintenance of
collection sewers within the City.
The Culver City Municipal Code (CCMC) Chapter 5.02: Sewers and Chapter 5.05 Stormwater and Urban
Runoff Pollution Control have been adopted by City Council to govern aspects of Culver City sewer
operations. The legal authorities for the specific areas stipulated in the WDRs are discussed below. The
codes, standard plans, specifications and other materials cited in this chapter are filed at the office of
the Director or Public Works/City Engineer.
a) Prevent illicit discharges into its sanitary sewer system (examples may include I/I, stormwater,
chemical dumping, unauthorized debris and cut roots, etc.);
Prevention
CCMC Section 5.02.410.A provides that the City’s collection system will accept liquid wastes
provided the wastes will not:
1. Damage structures;
2. Create nuisances such as odors;
3. Menace public health;
4. Impose unreasonable collection, treatment or disposal costs on the City;
5. Interfere with wastewater treatment processes;
6. Exceed quality requirements set by regulatory government agencies; or
7. Detrimentally affect the local environment.
To further regulate sewer discharges, CCMC Section 5.02.410.B adopted the following provisions of
the County of Los Angeles Code Title 20:
Chapter 20.20, Sections 20.20.010 through 20.20.420, Definitions;
Chapter 20.24, Sections 20.24.010 through 20.24.210, General Provisions;
Chapter 20.32, Sections 20.32.440 and 20.32.640 through 20.32.690, Sanitary Sewers;
Chapter 20.36, Sections 20.36.010 through 20.36.550, Industrial Waste.
All of the above provide adequate legal authority to prevent infiltration and inflow, stormwater,
chemical dumping, unauthorized debris and cut roots, etc.
b) Require that sewers and connections be properly designed and constructed;
Proper Design & Construction
CCMC Section 5.02.020, Connection Specifications, provides construction specifications for the
construction of connections to any City sewer. The City has adopted the Standard Specifications for
Public Works Construction (SSPWC). The SSPWC is used for the construction of all sewer facilities
constructed in the public right-of-way and inspections are performed by City staff through the Public
Works Encroachment Permit process authorized by CCMC Section 5.02.005.
Sewer System Management Plan (SSMP)
10
c) Ensure access for maintenance, inspection, or repairs for portions of the lateral owned or
maintained by the Public Agency;
Accessibility
Through adoption of the portions of Title 20, Division 2 of the Los Angeles County Code, Culver City
has the legal right to set requirements that allow unrestricted maintenance access to public sewer
infrastructure. This access is secured through enforcement of the requirement for sewer easements
around all public sewer appurtenances located in private properties and through prescriptive
easements. These easements are detailed by the designer on the sewer construction plans and are
reviewed through the iterative plan check process. Plan checkers take special care to ensure that
maintenance crews will have room for access and equipment usage for both routine maintenance
and replacement or repair construction as necessary. The Title 20 requirements to leave these
easements free of obstruction are also reiterated on all sewer plans that contain easements, and the
potential for conflict or restriction of access is reviewed carefully during plan check.
d) Limit the discharge of fats, oils, and grease and other debris that may cause blockages, and
Limiting the Discharge of FOG and other Debris
Culver City, under CCMC 5.02.410 and LACO Code Section 20.36.400, prohibits the discharge of
wastes that will damage the system or cause interference with conveyance or treatment processes.
Additionally, non-residential discharges are specifically subject to additional regulation as may be
required to protect the sewer system or to maintain its operation. Additional regulation would take
the form of the installation of grease interceptors at restaurants and other food establishments that
generate grease. Through adoption of LACO Code Section 20.24.090, Culver City has the legal
authority to inspect main-line sewers, sewage pumping plants, interceptors, etc., as often as
deemed necessary to verify that such facilities are maintained and operated in accordance with the
provisions of Division 2 of LACO Code.
Culver City contracts with the County of Los Angeles Department of Public Works, Environmental
Programs Division (Formerly Industrial Waste Division) (LACDPW) for the control of deleterious
substances. LACDPW administers the Industrial Waste Permit program in Culver City that reviews
development plans and requires pre-treatment devices where warranted. LACDPW also administers
the commercial site inspection program used to verify compliance with permit conditions and to
verify proper maintenance of pretreatment devices.
e) Enforce any violation of its sewer ordinances.
Enforcement
Under CCMC 5.02.410C and Section 20.24.100 of the LACO Code, the Director of Public Works/City
Engineer is empowered to enforce all the requirements prescribed in Division 2 – Sanitary Sewers
and Industrial Waste of the LACO Code and in accordance with section 20.24.110 may delegate this
authority. LACO Code Section 20.24.160 allows criminal penalties for any violations of the Sewer
and Industrial Waste Ordinances.
Sewer System Management Plan (SSMP)
11
4.0 OPERATION AND MAINTENANCE PROGRAM
a) Maintain an up-to-date map of the sanitary sewer system, showing all gravity line segments and
manholes, pumping facilities, pressure pipes and valves, and applicable stormwater conveyance
facilities;
Mapping System
As-built plans of Culver City sewer facilities are maintained by the Engineering Division of the Public
Works Department. Record drawings for most of the collection system and pump stations have
been scanned and are available through the City’s computer network. The City also maintains a GIS
system with a sewer GIS layer. The geodatabase includes manhole IDs, diameter and type, pipe
length and diameter, and CCTV inspection videos (if available) associated with each pipe segment.
Plans are available and can be accessed through the GIS system as well. The plans provide
information such as system locations and alignment, year of construction, pipe material and size,
etc. Original Mylars and linens are stored in the Engineering Division Office in City Hall located at
9770 Culver Boulevard, Culver City, California. These maps are distributed to field crews, for work
scheduling and for responding to emergencies. Mapping is updated to reflect changes in the system
as they occur or when they are detected.
A Preventive map is maintained that tracks when and where preventive maintenance is performed
in the system. A map of SSO locations is also maintained to assist in prioritization of maintenance
efforts and capital improvements.
A map showing the locations of Pump Stations and Maintenance facilities is presented in Appendix
C.
b) Describe routine preventative operation and maintenance activities by staff and contractors,
including a system for scheduling regular maintenance and cleaning of the sanitary sewer system
with more frequent cleaning and maintenance targeted at known problem areas. The
Preventative Maintenance (PM) program should have a system to document schedule and
conducted activities, such as work orders;
Preventative Maintenance (PM) Program
Culver City maintenance services and SSO responses are provided from the Culver City Maintenance
Facility located at 9505 Jefferson Boulevard in Culver City. The maintenance crews are equipped
with some of the latest technologies in the industry including radio equipped trucks for easy
communication, cellular phones, heavy and light construction equipment, vacuum trucks,
combination trucks, trailer mounted bypass pumps and bypass hose, generators, close circuit
television units for interior inspection of sewer lines and various types of safety equipment. A
complete inventory of Culver City equipment is presented in Appendix B.
The cornerstone of Culver City maintenance operation is the preventive maintenance program. This
program consists of regular inspection of the sewer system including manholes, pipes, siphons, and
pump stations and regular cleaning, repair, replacement of equipment and other related activities.
This program is designed and carried out to detect and correct potential problems before they
Sewer System Management Plan (SSMP)
12
develop into major problems. The following is a summary of the key preventive maintenance
activities and where applicable, frequencies for these services have been included:
? Sewer Line and Manhole Inspection
The interior and exterior of manholes are inspected at least annually to detect any structural
defects, sewage flow condition, presence of vermin or rodents, deleterious industrial waste,
odors and any signs of unusual settlement within sewer manholes maintained by Culver City.
These inspections are performed when sewer line cleaning is performed.
? Gas Trap Manholes and Siphons
On a monthly basis, these facilities are inspected and cleared of any stoppages or flow
restrictions.
? Drop Manholes
These facilities are inspected and cleared of stoppages and flow restrictions on variable
frequencies based on prior inspection records.
? Sewer Line Cleaning
Sewer lines are cleaned by hydro jet or rodding. Frequency of cleaning is based on inspection
records. Sewer lines known to accumulate grease or debris are put on, quarterly, semi-annual
or annual cleaning schedule, and those prone to root growth are periodically rodded or
chemically treated. Chemical root control is done annually for approximately 75,000 feet of
pipeline. Trouble areas will have Smart Covers installed and maintained twice a year.
? Vermin and Rodent Control
Sewers infested by insects are chemically treated. Those infested by rodents are baited.
? Sewage Pump Station
The City operates seven (7) sewer pump stations. All pump stations are equipped with
telemetry/alarm systems and are inspected weekly. Pumps and motors are lubricated, control
mechanisms and valves are checked and adjusted quarterly, and equipment is repaired or
modified as required. Routine maintenance of pump stations is scheduled through the
Maintenance Management System (MMS - MaintStar).
? Telemetry/ Emergency Notification System
The City contracts with a third-party vendor to monitor pump station telemetry and the
emergency notification systems. This system is a Motorola radio based system. The vendor
reviews telemetry performance and performs field inspections on a daily basis.
? Work Scheduling
Most work orders are generated and tracked using the Department’s Maintenance
Management System (MMS). The current system was developed and installed by MaintStar.
Maintenance regimens have been developed based on past maintenance history and work
orders are automatically issued by the system. When work orders are complete, field staff
acknowledges completion on the MMS.
Sewer System Management Plan (SSMP)
13
c) Develop a rehabilitation and replacement plan to identify and prioritize system deficiencies and
implement short-term and long-term rehabilitation actions to address each deficiency. The
program should include regular visual and TV inspections of manholes and sewer pipes, and a
system for ranking the condition of sewer pipes and scheduling rehabilitation. Rehabilitation and
replacement should focus on sewer pipes that are at risk of collapse or prone to more frequent
blockages due to pipe defects. Finally, the rehabilitation and replacement plan should include a
capital improvement plan that addresses proper management and protection of the infrastructure
assets. The plan shall include a time schedule for implementing the short- and long-term plans
plus a schedule for developing the funds needed for the capital improvement plan;
Rehabilitation and Replacement Plan
Sewer facilities assessment and rehabilitation are an integral part of Culver City’s preventive sewer
maintenance program. Through the condition assessment described below, the City identifies
portions of the system that require rehabilitation or replacement. Ongoing projects that complete
localized sewer pipe repair of trenchless repair or lining are completed annually. Additionally,
significant investment in system redundancy will occur in Fiscal years 2010-11, 2011-12, 2012-13.
Modifications to pump stations and construction of redundant force mains will be completed to
provide a more failsafe system.
Sewer pipelines in Culver City are made predominantly of vitrified clay with some plastic and
terracotta lines also in the system. Pipe sizes range from six to fifteen inches in diameter. The risk of
system failures increase with system age. Root intrusion and construction incursions are the
primary sources of structural damage. Conditions of concern include cracking, offset joints and
broken pipes which could lead to collapse and blockages. Excessive infiltration, the potential for
exfiltration, overflow, and other potential service interruptions are also areas of concern.
In an effort to overcome these challenges, the City inspected all 85 miles of sewer lines in 2001 using
a video inspection service. These inspections identified deterioration resulting in several sewer
rehabilitation projects. The City plans to re-inspect sewer lines on a six-year cycle. In 2010 and 2014
CCTV inspection efforts completed re-inspection of roughly two-thirds of the system. The remaining
third is scheduled in a future CIP.
Maintenance history, past overflow records, sewer locations, and age will be some of the factors
used to prioritize the CCTV schedule. The City’s GIS system is being upgraded to include CCTV
records accessible through the GIS system.
In 1987, Culver City established the Sewer Enterprise Fund for the maintenance and improvement of
the collection system. Many miles of sewer lines have been rehabilitated by lining or
reconstruction. In addition, some deteriorated lines are discovered during preventive maintenance
televising of problem sewer lines. These lines are either immediately repaired by City crews or by
emergency contractors or are added to the list of future Capital Improvement Projects (CIPs). In
compliance with WDR’s, all sewer pipe segments within Culver City found to have structural
deficiencies will continue to be rehabilitated or reconstructed through the Sewer CIP. Many
hydraulic deficiencies within the system have been addressed through previous projects.
Sewer System Management Plan (SSMP)

d) Provide training on a regular basis for staff in sanitary sewer system operations and maintenance,
and require contractors to be appropriately trained; and
Staff Training
Culver City staff responsible for the operation and maintenance of the sewer collection system and
City inspectors and engineering staff are well versed in sewer construction standards developed by
the American Public Works Association. City maintenance crews attend training provided by
California Occupational, Safety and Health Administration (CALOSHA), and City engineers attend
training provided by California Water Environment Association (CWEA). These trainings will keep
them abreast of the latest technology in the industry on how to safely and efficiently carry out their
tasks according to current regulations. The City also utilizes informal training approaches, such as
tailgate meetings and safety meetings. Records are kept of all training that is provided in support of
the SSMP. The records include the date, time, place, content, name of organization(s) and names of
attendees. As of April 2014, five (5) sewer crew employees completed Grade I CWEA and one (1)
completed Grade II CWEA certifications.
Additionally, sewer construction in Culver City can be performed only by construction companies
with verified successful experience working on sewer facilities.
e) Provide equipment and replacement part inventories, including identification of critical
replacement parts.
Equipment Maintenance and Replacement Policy
Culver City has a comprehensive equipment maintenance program. Equipment is regularly checked,
adjusted, repaired or replaced as necessary. Maintenance is performed by staff mechanics
according to manufacturer-recommended maintenance regimens. Equipment replacement is
accomplished through an equipment replacement fund. Funds are set aside annually based on
estimated equipment life and replacement cost.
All the critical spare parts have been identified for each station, and Mesmer Pump Station is the
main storage place for all spare parts. US|1010| (third-party telemetry contractor) assists the sewer crew
in stocking electrical components and variable speed switches. Each pump station has spare pumps
and motors for emergencies.

5.0 DESIGN AND PERFORMANCE PROVISIONS:
a) Design and construction standards and specifications for the installation of new sanitary sewer
systems, pump stations and other appurtenances; and for the rehabilitation and repair of existing
sanitary sewer systems; and
Design and Construction Standards and Specifications
All sewer construction in Culver City must be performed according to the Standard Plans and
Specifications for Public Works Construction developed by the American Public Works Association.
The use of these standards ensures that sewer lines and connections are properly designed and
constructed. To further assure that sewer facilities are properly designed and constructed, Culver
City requires that plans are designed by licensed engineers and provides thorough review of plans
by a California licensed Civil Engineer prior to approval.
APWA Greenbook standards and specifications are used in the construction of sewer facilities and
registered civil engineers must design any proposed sewers. Projects initiated and funded by the
City are designed either by City engineers or, where additional expertise is required, consultant
engineering support is used.
b) Procedures and standards for inspecting and testing the installation of new sewers, pumps, and
other appurtenances and for rehabilitation and repair projects.
Procedures and Standards for Inspection and Testing
The Culver City Public Works Department provides inspection for the installation of new and
rehabilitation of deteriorated collection sewer facilities within the City. City inspectors and staff are
well trained in pipeline and pump station construction. They attend training classes and educational
seminars to stay familiar with advancements in the industry. The inspectors are also provided with
adequate materials to perform their jobs, including the Standard Specifications for Public Works
Construction Inspection Manual (the Green Book). The City requires the preparation and submittal
of “As-Built” plans of completed projects prior to final approval and acceptance of the project as
public infrastructure.

6.0 OVERFLOW EMERGENCY RESPONSE PLAN
6.1 Introduction
This section of the SSMP is intended to provide an overview of the City’s sanitary sewer system Overflow
Emergency Response Plan. This Overflow Emergency Response Plan has been developed pursuant to
State Water Resources Control Board guidelines requiring all public wastewater collection system
agencies in California be regulated under General Waste Discharge Requirements.
6.2 Regulatory Requirements for the Overflow Emergency Response Plan Section
The WDR requirements for the Overflow Emergency Response Plan are: Each Enrollee shall develop and
implement an overflow emergency response plan that identifies measures to protect public health and
the environment. At a minimum, this plan must include the following:
a. Proper notification procedures so that the primary responders and regulatory agencies are
informed of all SSO’s in a timely manner;
b. A program to ensure an appropriate response to all overflows;
c. Procedures to address emergency operations, such as traffic and crowd control and other
necessary response activities;
d. A program to ensure that all reasonable steps are taken to contain and prevent the discharge
of untreated and partially treated wastewater to waters of the United States and to minimize
or correct any adverse impact on the environment resulting from the SSO’s, including such
accelerated or additional monitoring as may be necessary to determine the nature and impact
of the discharge;
e. Procedures to ensure prompt notification to appropriate regulatory agencies and other
potentially affected entities (e.g. health agencies, Regional Water Boards, water suppliers,
etc.) of all SSO’s that potentially affect public health or reach water of the State in accordance
with the MRP. All SSO’s shall be reported in accordance with this MRP, the California Water
Code, other State Law, and other applicable Regional Water Board WDR’s or NPDES permit
requirements. The SSMP should identify the officials who will receive immediate notification;
and
f. Procedures to ensure that appropriate staff and contractor personnel are aware and follow
the Overflow Emergency Response Plan and are appropriately trained.
Sewer System Management Plan (SSMP)
17
6.3 SSO RESPONSE PLAN
The following Overflow Emergency Response Plan (EORP) complies with all the requirements of the
WDR as listed above and is tailored to the City of Culver City.
6.3.1 Initial Notification of SSO and Call-Out
A Notification by SCADA system or SmartCover manhole covers will be issued to the Sewer Lead Worker
through automated cell phone notification. If the Sewer Lead Worker is not available, the system will
continue to dial phone numbers to contact City staff according to a specified order culminating in
telephonic contact to the Director of Public Works/City Engineer. The party successfully notified shall
contact the Sewer Maintenance Crew Leader at (310) 849-8937 and call the Sewer Maintenance Pager
at (310) 917-2036. SSOs reported by the public during business hours will be routed to the Public Works
Department for response as described above. SSOs reported by the public after business hours will be
received by the Fire Department who will contact Sewer Maintenance staff through the contacts above.
Upon being notified of the emergency, the Sewer Lead Worker or on-call sewer maintenance staff shall
call-out additional staff to the location of the alarm and shall contact the Maintenance Operation
Division Manager [(310) 253-6444] who will be deployed to the site and will assume the role of Incident
Commander. Staff shall arrive as quickly as possible and be equipped with equipment and materials
necessary to contain the spill.
Environmental Programs and Operation (EPO) Division staff shall be contacted to deploy to the site to
assess flow volumes and risk to waters of the United States (Ballona Creek or Marina del Rey Harbor).
EPO staff will determine the Category of the spill as follows:
? Category 1: all discharges of sewage resulting from a failure in the sanitary sewer system that:
a) Result in a discharge of any volume to a drainage channel and/or surface water; or
b) Discharge to a storm drain that was not fully captured and returned to the sanitary
sewer system
? Category 2: all discharges of sewage resulting from a failure in the sanitary sewer system that:
a) Equal or exceed 1,000 gallons, and
b) Result in a discharge that does not reach a drainage channel, surface water or storm
drain; or,
c) Result in a discharge to a storm drain system that is fully captured and returned to the
sanitary sewer system.
? Category 3: All discharges possessing the same characteristics of a Category 2 SSO except the
volume of discharge is less than 1000 gallons.
? Private Lateral Sewage Discharges: sewage discharges that are caused by blockages or other
problems within a private owned lateral.
If the spill is determined to be Category 1, EPO staff will report the spill to California Emergency
Management Agency (CalEMA) at (800) 852-7550 as soon as is practicable but no later than 2 hours
from the City becoming aware of the spill and will obtain a CalEMA Control Number for the spill. EPO
staff will consult with operations staff to determine the estimated start time of the spill and the flow
rate of the spill. EPO staff will also take sufficient photographs to document the spill response,
Sewer System Management Plan (SSMP)
18
containment activities and clean-up. EPO staff will also document the SSO discharge point to use in
estimating the discharge volume.
6.3.2 Containment
The primary goal in the spill response is containment. To accomplish containment a minimum, two
combination trucks shall be deployed to the SSO location. One Combination truck shall be deployed to
contain and vacuum extract SSO discharges such that discharges to the storm drain are minimized or
prevented. The other combination truck shall be deployed to the site of the sewer blockage to remove
the blockage and restore sewer operation. If the blockage cannot be removed within a short period of
time (say 30 minutes), a bypass pump shall be deployed to pump around the blockage. If the spill is the
result of pump station or force main failure, staff shall deploy a bypass pump using suction and
discharge hoses leading from the pump station wet well and connected to a bypass connection on the
force main (if the force main is so equipped) or to a manhole draining to an adjacent sewage drainage
area (refer to GIS map book to identify available discharge locations).
If any sewage has entered the storm drain, construct a containment dam where the storm drain outlets
to Ballona Creek and station a combination truck at the outlet to vacuum extract all contained sewage.
In areas that drain to Marina del Rey Harbor, a containment dam will not be required due to the
existence of a low flow diversion facility that diverts all dry-weather flow to the sanitary sewer for
treatment at the Hyperion Treatment Plant.
6.3.3 Traffic Control and Protection of Public
The incident first responder shall assess whether traffic control and/or barricades are required to
provide a safe working area and to protect the public from contacting the spill area.
6.3.4 Additional Resources
If additional resources are required (e.g. additional pumps, combination trucks, baker tanks etc.) contact
the vendors listed later in this section.
6.3.5 Cleanup
Once the sewer blockage has been cleared or pump station has been returned to service, the cleanup
phase begins. Sewer crews will leave all containment berms and dams in place and will begin washing
all surfaces contacted by the spill. A 20:1 bleach solution shall be used on all streets and other paved
surfaces and only clean water shall be used within underground storm drains. All wash water shall be
captured and disposed of in the sanitary sewer. A contractor may be called to assist with clean-up
activities. (i.e. Ocean Blue Environmental Services; 1-800-990-9930)
6.3.6 Estimated Spill Volume
EPO staff will take measurements and photographs required to estimate the flow rate of the spill.
Photographs of the manhole discharge condition shall be compared to the photographs in Appendix F.
Other spill volume methods that may be used are described in Appendix F.
6.3.7 Monitoring
If the amount of the spill exceeds 50,000 gallons, the City must sample waters within Ballona Creek
within 48 hours of becoming aware of the SSO. Samples shall be taken upstream and downstream of
where the spill entered the Creek. The samples shall be taken using special vessels provided by the
Sewer System Management Plan (SSMP)
19
City’s contracted laboratory, placed on ice and transported to the laboratory (see contact for Sewage
Spill Sampling Laboratory listed later in this section).
If the spill enters Ballona Creek upstream of National Boulevard, the samples shall be tested for:
a. Ammonia
b. E-coli
If the spill enters Ballona Creek downstream of National Boulevard, the samples shall be tested for:
c. Ammonia
d. E-coli, coliform, enterococcus
6.3.8 Spill Reporting
EPO staff must enter information on any category spill into the California Integrated Water Quality
System (CIWQS) at the following web address https://ciwqs.waterboards.ca.gov/ciwqs/index.jsp. A
draft of the report shall be entered within three business days and the final report shall be certified by
the Legally Responsible Official (Director of Public Works/City Engineer) within 15 calendar days of the
spill.
6.3.9 Technical Report
If a Category1 spill exceeds 50,000 gallons a technical report must be prepared and uploaded to the
CIWQS by EPO within 45 calendar days of the spill. The required format of the technical report is
indicated in Order No. WQ 2013-EXEC Section C.5 provided in Appendix A.

7.0 FOG CONTROL PROGRAM
a) An implementation plan and schedule for a public education outreach program that promotes
proper disposal of FOG;
Public Education Outreach Program
Culver City contracts with the County of Los Angeles Department of Public Works, Environmental
Programs Division (Formerly Industrial Waste Division) (LACDPW) to implement its FOG program.
LACDPW staff inspect restaurants and industrial facilities to assure that appropriate grease
interception devices are installed and maintained. Inspectors provide information on proper
installation, maintenance and operation of pretreatment facilities. LACDPW staff also review
development plans to determine and require pretreatment facilities if they are deemed necessary.
City staff work closely with LACDPW staff and assist with enforcement actions when needed.
b) A plan and schedule for the disposal of FOG generated within the sanitary sewer system service
area. This may include a list of acceptable disposal facilities and/or additional facilities needed to
adequately dispose of FOG generated within a sanitary sewer system service area;
Disposal
Solidified fats found in the collection system during cleaning operations are trapped, collected and
taken to the maintenance yard dump bins. These and other debris collected from the system are
properly disposed of. FOG in liquid form is flushed down by hydro jetting to City of Los Angeles’
treatment facilities for treatment and disposal.
c) The legal authority to prohibit discharge to the system and identify measures to prevent SSOs and
blockages caused by FOG;
Legal Authority
The legal authority to prohibit discharges of FOG into the sewer system is discussed in Chapter 3 of
this document. Requiring grease interceptors at food establishments to prevent the discharge of
grease to the collection sewer system and educating the public on proper disposal methods for FOG
are also discussed.
d) Requirements to install grease removal devices (such as traps or interceptors), design standards
for the removal devices, maintenance requirements, BMP requirements, record keeping and
reporting requirements;
Grease Removal Devices
As provided in CCMC Section 5.02.410.B, the Director of Public Works/City Engineer is authorized to
enforce Title 20, Division 2, Section 20.24.100. Pretreatment devices are required for industrial
waste generating facilities, including restaurants and other food establishments. They are required
to be designed in accordance with County Industrial Waste standards and installed and operated in
a manner to control discharges of FOG into the sanitary sewer system. If there is a FOG related
problem associated with an industrial waste permit, City staff will take enforcement action against
the permittee.
Sewer System Management Plan (SSMP)
25
The City does not issue permits or inspect domestic sewage disposal to the sanitary sewer system.
However, the LACO Code prohibits the discharge of “any material which may create a public
nuisance, or menace to the public health or safety, or which may pollute underground or surface
waters, or which may cause damage to any storm-drain channel or public or private property”
(Section 20.36.010). If during inspection of the sanitary sewer system City staff determines that a
FOG related problem exists and is traceable to a domestic sewage source of such character that is
not satisfactory (Section 20.20.100), under the County Code, pretreatment could be required or the
discharge required to be eliminated. Domestic waste containing FOG can lead to SSOs which are
public nuisances, and California Health and Safety Code Division 5, Part 3, Chapter 6, Article 2 can
also be used to impose appropriate domestic sewage discharge requirements.
e) Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee
has sufficient staff to inspect and enforce the FOG ordinance;
Authority to Inspect
As discussed in Chapter 3 of this document Culver City has the legal authority to inspect and enforce
the Los Angeles County FOG ordinances. As mentioned above, the City has contracted with the
County of Los Angeles Department of Public Works, Environmental Programs Division (LACDPW) to
implement its FOG Program LACDPW has adequate staff to conduct inspections of pretreatment
facilities at all permitted food establishments within Culver City through a permit program. Fees
generated through the permit program fund the City FOG program.
f) An identification of sanitary sewer system sections subject to FOG blockages and establishment of
a cleaning maintenance schedule for each section; and
Cleaning Schedule
Experience has shown that FOG contributes to about 30% of the total number of SSOs that occur in
Culver City sewer collection system. The remaining 70% is attributable to tree root intrusion into
the system and other causes. As indicated in Chapter 4 of this document, FOG prone sections of the
collection system are identified during routine maintenance operations and investigation of
stoppages and SSOs. These are typically cleaned by hydro jetting and rodding if tree roots are
encountered. Those portions of the system found to have persistent FOG problems are cleaned
quarterly or more frequently if required. Furthermore, areas of the collection system with
persistent FOG problems are referred to LACDPW for additional investigation and enforcement
actions.
g) Development and implementation of source control measures for all sources of FOG discharged to
the sanitary sewer system for each section identified in (f) above.
Source Control Measures
The LACDPW FOG program investigates and identifies sewer users that contribute FOG to the City’s
system. When a source is discovered, steps are taken to ensure SSO does not occur. Such source
control measures include the requirement that pretreatment systems be installed and maintained
adequately to remove as much FOG as practicable
Sewer System Management Plan (SSMP)
26
8.0 SYSTEM EVALUATION AND CAPACITY ASSURANCE PLAN
a) Evaluation: Actions needed to evaluate those portions of the sanitary sewer system that are
experiencing or contributing to an SSO discharge caused by hydraulic deficiency. The evaluation
must provide estimates of peak flows (including flows from SSOs that escape from the system)
associated with conditions similar to those causing overflow events, estimates of the capacity of
key system components, hydraulic deficiencies (including components of the system with limiting
capacity) and the major sources that contribute to the peak flows associated with overflow
events;
System Evaluation and Capacity Assurance
Culver City’s Public Works Department is staffed with engineers and technical personnel trained in
proper and safe design and construction of sanitary sewer systems. The maintenance crews
evaluate pump stations and sewer lines on a weekly basis to detect any system capacity deficiencies.
Presently, the City’s sewer system appears to possess sufficient capacity. To verify system capacity
and to detect any deficiencies, the City will conduct a Sewer System Master Plan in 2014-15. This
Master Plan recommend a capital improvement plan to address any system deficiencies or system
deterioration.
b) Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation
identified in (a) above to establish appropriate design criteria; and
Adequate Capacity and Correct Design
Title 20, Division 2 of the L.A. County Code as adopted by Culver City provides the legal responsibility
for ensuring sound and functional design of the public sewer infrastructure. The L.A. County Code
also forms the basis upon which sewer construction plans are designed and plan checked.
During the development process, developers must perform a study to determine the impacts of flow
to be added to the system. The study will analyze the capacity in the existing system and will set
forth mitigation requirements to ensure adequate capacity. The study will also justify the sizing of
proposed lines to accommodate the peak flows from all areas tributary to the impacted mainline
sewer or pumping station using present and estimated future flows. Permits for construction of any
public sewer infrastructure are not issued until the iterative plan check process has been satisfactory
completed, thus insuring the functional design and adequate capacity of the public sewer collection
system.
c) Capacity Enhancement Measures: The steps needed to establish a short- and long-term CIP to
address identified hydraulic deficiencies, including prioritization, alternatives analysis, and
schedules. The CIP may include increases in pipe size, I/I reduction programs, increases and
redundancy in pumping capacity, and storage facilities. The CIP shall include an implementation
schedule and shall identify sources of funding.
Capacity Enhancement
The City will conduct a Sewer System Master Plan in 2014-15. This Master Plan will recommend a
capital improvement plan to address any system deficiencies or system deterioration. The most
Sewer System Management Plan (SSMP)
27
significant capacity deficiency will be addressed in the short-term CIP. Lesser deficiencies will be
addressed in the long-term CIP.
The City is currently in the design phase of a project to eliminate four pump stations through the
construction of a single, larger station with quadruple redundancy.
All CIP funding will come from the sewer enterprise fund.
d) Schedule: The Enrollee shall develop a schedule of completion dates for all portions of the capital
improvement program developed in (a)-(c) above. This schedule shall be reviewed and updated
consistent with the SSMP review and update requirements as described in Section D.14.
CIP Schedule
Each CIP will have its own completion date. However, due to some uncertainties, the dates may
change as necessary to reflect any required changes. The SSMP will be modified accordingly to each
CIP’s progress and success.

9.0 MONITORING, MEASUREMENT, AND PROGRAM MODIFICATIONS
a) Maintain relevant information that can be used to establish and prioritize appropriate SSMP
activities;
Database & Record Keeping
All data and records are kept on the Maintenance Management System (MMS – MaintStar) of the
Public Work’s Maintenance and Operations Division. This system also generates and track work
orders for the sewer crews. Daily maintenance records are archived in hard copy format in the
office of the WDR engineer.
b) Monitor the implementation and, where appropriate, measure the effectiveness of each element
of the SSMP;
Implementation and Effectiveness of SSMP
Relevant data on all work done in the implementation/execution of the SSMP program shall be
documented in the MMS and used in preparing Culver City monthly summary of workload
indicators. These data are used in the evaluation of the effectiveness of the overall program.
c) Assess the success of the preventative maintenance program;
Assessment of Preventative Maintenance Program
The effectiveness of the program shall be monitored and tracked by Culver City Maintenance staff.
The primary goal of the SSMP is the reduction/elimination of SSOs, therefore, the primary measure
of effectiveness of the SSMP is the number of SSOs encountered. Other measures will be total
number of category 1, 2, and 3 SSOs, overflow response time, reduction in repeated incidents of
overflow at same location and reduction in number of overflows caused by flows exceeding the
capacity of the collection system including pump stations.
SSO occurrences have reduced since 2007. In 2007, ten (10) SSOs occurred, and only four (4) SSOs
were experienced in 2013. There were three locations where multiple SSOs occurred. Smart covers
were installed at these locations to allow preventive measures to be performed to prevent the SSO.
d) Update program elements, as appropriate, based on monitoring or performance evaluations; and
Updates
Based on the above monitoring measures, the SSMP will be updated or modified as necessary.
e) Identify and illustrate SSO trends, including: frequency, location, and volume.
Trending and Analysis of SSOs
The locations of SSO occurrences are plotted annually on City maps (Appendix D). The causes of the
SSO are also recorded. These maps are used for establishing SSOs patterns, identifying hot spots as
indicated by clusters on the maps, and for scheduling work assignments. The SSO numbers are also
depicted in tables. The tables are used to identify SSO trends and to evaluate overall SSMP program
success especially by comparing the graphs to different years and with results from other sewer
agencies.
Sewer System Management Plan (SSMP)
29
10.0 SSMP PROGRAM AUDITS
a) The Enrollee shall conduct periodic internal audits, appropriate to the size of the system and the
number of SSOs. At a minimum, these audits must occur every two years and a report must be
prepared and kept on file. This audit shall focus on evaluating the effectiveness of the SSMP and
the Enrollee’s compliance with the SSMP requirements identified in this subsection (D.13),
including identification of any deficiencies in the SSMP and steps to correct them.
Program Audit
Culver City will conduct an internal audit and prepare a report every two years. The audit shall focus
on evaluating the effectiveness of the SSMP and compliance with the SSMP requirements including
identification of any deficiencies in the SSMP and steps to correct them. The audit shall also rely on
interviews with key personnel, observations, equipment inspections and review of records, etc. The
most recent report of the audit must be kept on file in the Public Works Department with a copy at
the field maintenance yard.
The SSMP shall be certified by the Director of Public Works or authorized representatives to be in
compliance with the requirements set forth in the WDR’s and be presented to the City Council for
approval at a public meeting. The Culver City authorized representative must also complete the
certification portion in the Online SSO Database Questionnaire by checking the appropriate
milestone box, printing and signing the automated form and sending the signed form to
State Water Resources Control Board
Division of Water Quality
Attn: SSO Program Manager
P.O. Box 100
Sacramento, CA 95812
The SSMP must be updated every five years. When significant amendments are made to any
portion or portions of the SSMP, it must be resubmitted to the City Council for approval and re-
certification. The re-certification shall be in accordance with the certification process described
above.
Sewer System Management Plan (SSMP)
30
11.0 COMMUNICATION PROGRAM
a) The Enrollee shall communicate on a regular basis with the public on development,
implementation, and performance of its SSMP. The communication system shall provide the
public the opportunity to provide input to the Enrollee as the program is developed and
implemented.
Communication
Culver City will provide all stakeholders and interested parties with status updates on the
development and implementation of the SSMP and consider comments made by them. Culver City
may use media such as, annual reports, notices in newspapers, and the City’s web site to convey this
information.
Copies of the SSMP will be maintained in Culver City City Hall, in the Culver City Maintenance Facility
and on the City’s Website. The document will also be made readily available to Regional Water
Quality Control Board representatives upon request and to the operators of any collection system or
treatment facility downstream of Culver City’s system.
b) The Enrollee shall also create a plan of communication with systems that are tributary and/or
satellite to the Enrollee’s sanitary sewer system.
Tributary & Satellite Communication
The City has a contract with the City of Los Angeles. Both cities update one another with new
projects and maintenance.

METHODS FOR ESTIMATING SPILL VOLUME
Sewer System Management Plan (SSMP)

Methods for Estimating Spill Volume
A variety of approaches exist for the estimation of the volume of a sanitary sewer overflow. This appendix
documents the three methods that are most often employed. The person preparing the estimate should
use the method most appropriate to the sewer overflow in question using the best information available.
Every effort should be made to make the best possible estimate of SSO volume.
Method 1: Eyeball Estimate
The volume of small spills can be estimated using an “eyeball estimate”. To use this method imagine the
amount of water that would spill from a bucket or a barrel. A bucket contains 5 gallons and a barrel
contains 50 gallons. If the spill is larger than 50 gallons, try to break the standing water into barrels and
then multiply by 50 gallons. This method is useful for contained spills up to 200 gallons.
Method 2: Measured Volume
The volume of most small spills that have been contained can be estimated using this method. The shape,
dimensions, and the depth of the spilled wastewater are needed. The shape and dimensions are used to
calculate the area of the spills and the depth is used to calculate the volume.
Step 1 – Sketch the shape of the contained sewage
Step 2 – Measure or pace off the dimensions
Step 3 – Measure the depth at several locations and select an average
Step 4 – Convert the dimensions, including depth to feet
Step 5 – Calculate the area in square feet using the following formulas:
Rectangle: Area = length (feet) x width (feet)
Circle: Area = 0.785 x D|1010| (where D is diameter of the spill)
Triangle: Area = base (feet) x height (feet) x 0.5
Step 6 – Multiply the area (square feet) times the depth (in feet) to obtain the volume in cubic feet
Step 7 – Multiply the volume in cubic feet by 7.48 to convert it to gallons
Method 3: Duration and Flow Rate
Calculating the volume of spills where it is difficult or impossible to measure the area and depth requires a
different approach. In this method a separate estimate is made of the duration of the spill and the flow
rate. The methods of estimating duration and flow rate are:
Duration: The duration is the elapsed time from the time the spill started to the time that the spill ended.
Start time: The start time is sometimes difficult to establish. Here are some approaches:
? Local residents can be used to establish start time. Inquire as to their observations. Spills that occur
in rights-of-way are usually observed and reported promptly. Spills that occur out of the public view
can go on longer. Sometimes observations like odors or sounds (e.g. water running in a normally dry
creek bed) can be used to estimate the start time.
? Changes in flow on a downstream flowmeter can be used to establish the start time. Typically the
daily flow peaks are “cut off” or flattened by the loss of flow. This can be identified by comparing
hourly flow data, when available.

? Conditions at the spill site change with time. Initially there will be limited deposits of grease, toilet
paper, and other sewage solids. After a few days to a week, the sewage solids forms a light-colored
residue. After a few weeks to a month it turns dark. In both cases the quantity of toilet paper and
other materials of sewage origin increase in amount. These changes with time can be used to
estimate the start time in the absence of other information. Taking photographs to document the
observations can be helpful if questions arise later in the process.
End time: The end time is usually much easier to establish. Field crews on-site observe the “blow down”
that occurs when the blockage has been removed. The “blow down” can also be observed in
downstream flowmeters.
Flow Rate: The flow rate is the average flow that left the sewer system during the time of the spill. There
are three ways to estimate the flow rate:
? The San Diego Manhole Flowrate Chart: This chart shows the sewage flowing from a standard
manhole cover for a variety of flowrates. The observations of the field crew can be used to select
the approximate flowrate from the chart. If possible, photographs are useful in documenting basis
for the flowrate estimate.
? Flowmeter: Changes in flows in the downstream flowmeters can be used to estimate the flowrate
during the spill.
? Counting Connections: Once the location of the spill is known, the number of upstream connections
can be determined form the sewer maps. Multiply the number of connection by 200 to 250 gallons
per day per connection or 8-10 gallons per hour per connection.
For example: 15 upstream connections x 9 gallons per hour per connection
= 135 gallons per hour / 60 minutes per hour
= 2.25 gallons per minute
Spill Volume: Once duration and flow rate have been estimated, the volume of the spill is the product of
the duration in hours or days times the flow rate in gallons per hour or gallons per day.
For example: Spill duration = 3 hours
2.25 gallons per minute x 3 hours x 60 minutes per hour = 405 gallons
