City Council Meeting: May 23, 2023
Agenda Item: 5.C
1 of 3
To: Mayor and City Council
From: Rick Valte, Public Works Director, Public Works, Water Resources
Subject: Adoption of a Resolution Approving the City's Sewer System Management
Plan Update
Recommended Action
Staff recommends that the City Council:
1. Adopt the attached resolution approving the City’s Sewer System Management
Plan (SSMP) Update and Certifying it is consistent with Statewide General Waste
Discharge Requirements (WDRs) for Sanitary Sewer Systems.
2. Adopt a finding of Categorical Exemption pursuant to Section 15308 (Actions for
Protection of the Environment), of the California Environmental Quality Act
(CEQA) Guidelines.
Summary
The City of Santa Monica’s Water Resources Division within the Public Works
Department operates and maintains the City’s sanitary sewer system, which consists of
approximately 150 miles of sewer main, a sanitary sewer lift station (Moss Avenue
Pump Station), and 2,800 maintenance utility holes. The City is required to update its
Sewer System Management Plan (SSMP) periodically to comply with statewide Waste
Discharge Requirements (WDR) administered by the California State Water Resources
Control Board. The WDR permit requires the City to operate and maintain sanitary
sewer systems to prevent spills and to eliminate discharge of sewage into waters of the
State through effective implementation of the SSMP, among other requirements. The
Water Resources Division recently updated the City’s SSMP, which requires
recertification by City Council prior to submittal to the California State Water Resources
Control Board. Staff recommends that City Council recertify the City’s revised SSMP. By

recertifying the SSMP, the City would reinforce its commitment to managing the sanitary
sewer system in a manner that protects public health and natural resources.
Discussion
On May 2, 2006, the California State Water Resources Control Board announced
requirements for a statewide waste discharge requirements permit (Order NO. 2006-
0003-DWQ) to regulate sanitary sewer systems. The California State Water Resources
Control Board requires public entities that own and/or operate one or more sanitary
sewer systems greater than one (1) mile in length to obtain a WDR permit for sanitary
sewer systems. The City currently holds a WDR permit for its sanitary sewer system
and the first SSMP was approved by City Council on September 8, 2009. The City’s
recently completed Sustainable Water Infrastructure Project (SWIP) is regulated under
its own WDR permit (Order No. R4-2021-0044) to produce advanced treated recycled
water for non-potable uses (e.g., irrigation and dual-plumbed buildings) and
groundwater recharge. Thus, discussion of the SWIP is not included in the SSMP.
The purpose of the SSMP is to identify necessary administrative elements to properly
schedule, manage, operate, and maintain all parts of the City’s sanitary sewer system,
to reduce and prevent sanitary sewer overflows, and to mitigate any overflow events
that do occur. In October 2022, The Water Resources Division commenced efforts to
update the City’s Sanitary Sewer Master Plan and key proposed updates include a
chain of communications for reporting sanitary sewer overflows, addition of pertinent
sections of the City’s Municipal Code (SMCC 5.20, 7.04, 7.68) to establish legal
authority for WDR compliance, response actions to overflow events, routine
maintenance activities performed by the City, and updated historical information on
overflow events in the City.
The updated SSMP must be recertified by City Council prior to it being submitted to the
California State Water Resources Control Board in May 2023.

Environmental Review
Updating the City’s Sewer System Management Plan is categorically exempt from
CEQA pursuant to Section 15308 (Class 8 - Actions for Protection of the Environment)
of the CEQA Guidelines. Section 15308 exempts actions taken by regulatory agencies
for protection of the environment. The SSMP establishes the administrative elements
and guidelines to prevent and mitigate sewer overflow events in an effort to protect the
environment.

Introduction
The California State Water Resources Control Board (“SWRCB”) promulgated a waste discharge
requirement (“WDR”) permit on May 2, 2006 to regulate sanitary sewer systems. This permit is known
as SWRCB Order No. 2006-0003, Statewide General Waste Discharge Requirements for Sanitary Sewer
Systems. On July 30, 2013, Attachment A to the Order was promulgated and became effective on
September 9, 2013 and is known as Attachment A, SWRCB Order No. WQO 2013-0058-EXEC, amending
the Monitoring and Reporting Program for Statewide General Waste Discharge Requirements for
Sanitary Sewer Systems (together these documents constitute the “SSS WDR”). Recently, a reissuance of
the General Order occurred to update the 16-year-old Order. Order 2022-0103-DWQ will be in effect
as of June 5, 2023. This Sewer System Management Plan (SSMP) is intended to update the City’s
existing SSMP, in continued compliance with the WDR.
System Overview
The City of Santa Monica, Department of Public Works – Water Resources Division (WRD) provides
wastewater collection services over 8.25 square miles in area and servces a resident population of
approximately 91,105 (2021). In addition to collecting sewage from parcels within its corporate
boundaries, the WRD also collects pass-through flow from the City of Los Angeles, via the Coastal
Interceptor System (CIS) and unmetered locations, and conveys (via pumps and/or gravity collection) the
sewage to the City of Los Angeles Hyperion Water Reclamation Plant for treatment and disposal.
The WRD is responsible for wastewater collection and pumping in the City, which consists of
approximately 154 miles of sewer pipe ranging in diameter from 6-inches to 72-inches, over 2,800
maintenance manholes, two flow-monitoring and sampling stations, and the Moss Avenue Pumping
Station (MAPS) that has a pump capacity of 26- million gallons per day (mgd). Sewage also enters Santa
Monica from the City of Los Angeles through one metered location and from three unmetered locations
and leaves Santa Monica for treatment at the City of Los Angeles Hyperion Water Reclamation Plant
through one metered and six unmetered locations. The City of Santa Monica’s 72-inch CIS connection to
the City of Los Angeles was designed for the development sunset year of 2090 and has a capacity of
approximately 52 mgd. The CIS is owned and maintained by the City of Los Angeles. Presently, the
maximum peak instantaneous flow approaches 32.67 mgd and the annual daily averages flow is
approximately 14.54 mgd. This flow rate includes all dry weather runoff diversions into the sanitary
sewer systems. Long-term build out (e.g., 2020 Regional Housing Needs Assessment) and populaion
density increases is evaluated through the City’s WAter and Wastewater Master Plans that is updated
every four to five years. Asthe City recognizes the importance of planning for all aspects of future
development, water and sewer capacity and demand forecasts are reviewed regularly and updated as
needed to keep abreast of changing conditions.
The WRD is also responsible for all water-related assets that support the safe treatment and distribution
of potable and recycle water within the City, as well as the collection and conveyance of all sanitary and

3.2 Agreement with Satellite Agency
The City of Santa Monica does not have a large enough treatment plant to treat all of the wastewater
generated in the city. For this reason, there is an agreement with the City of Los Angeles to accept
wastewater from Santa Monica. The City of Los Angeles charges Santa Monica based on the amount
and strength of flow that is sent to the Hyperion Water Reclamation Plant for final treatment and
disposal. These measurements are taken at two outfalls just at the entrance of Santa Monica city limits
and right before flow leaves the city.
The City of Los Angeles has tributary areas that combine with sewage from the City of Santa Monica.
These tributaries feed into six different locations around Santa Monica that eventually pass through
back into the LA sewer system. The largest amount of pass through comes via the Coastal Interceptor
System (CIS) which transports flow from areas upstream of Santa Monica’s service area.

ELEMENT 4 - OPERATIONS AND MAINTENANCE (O & M) PROGRAM
SWRCB Requirement:
The SSMP must include those elements listed below that are appropriate and applicable to the
Enrollee’s system:
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 storm water conveyance
facilities;
b. Describe routine preventive 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 scheduled and
conducted activities, such as work orders;
c. Develop 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;
d. Provide training on a regular basis for staff in sanitary sewer system operations, maintenance,
and require contractors to be appropriately trained; and
e. Provide equipment and replacement part inventories, including identification of critical
replacement parts.
4.1 Collection System Maps
The WRD ESRI-GIS database was initially based upon as-built record drawings and was limited to
horizontal data. As time progressed, more field information (e.g., elevation and pipe slope) is added to
the GIS database. Linear assets older than 75 years usually have limited construction data and the
record as-built drawings associated with the assets provide the best engineering data. As the WRD’s
asset management plan grows, more information is incorporated including vertical pipe invert and soffit
elevations, manhole rim elevations and pipe segment slopes. The database is continuously growing and
is also tied to the WRD’s maintenance management system.
5.C.c
Packet Pg. 187 Attachment: Draft Sewer System Management Plan Update 2023 (5683 : Sanitary Sewer Management Plan)
SEWER SYSTEM MANAGEMENT PLAN 2023
WRD SSMP Operations and Maintenance Program Element 4 Page 4-2
The City also has limited copies of its older (1960) sewer atlas, which provides some additional data, and
can be used to find appropriate as-built drawings. The last update of the sewer atlas occurred in 2000, at
which time the City switched to the current GIS system.
As-built drawings are on file at the City’s Department of Public Works – Engineering Division. The
Engineering Division is also responsible for the construction of the collection system assets. The City is
in the process of incorporating these drawings into the GIS format as funding and resources allows.
Collections system maps are revised as necessary when discrepancies are discovered in the field.
Wastewater crew relay the changes to the supervisor who then passes the information to the
Engineering division for revision in the GIS system. Field crews are equipped with hard copies of the
maps, tablets for digital access, and access to the Hansen database for work order observations.
4.2 Preventative Maintenance
The elements of the City’s sewer system operation and maintenance (O&M) program include:
x Preventative and corrective maintenance;
x Closed Circuit Television (CCTV) inspections in order to evaluate the condition of the gravity
sewers;
x Routine sewer jetting to maintain gravity flow and minimize SSOs;
x Replacement and repair of sewers that are in poor condition.
4.2.1 Computer Maintenance Management Systems (CMMS)
To plan and track O&M activities, the City utilizes a computerized maintenance management system
(CMMS). The CMMS (Hansen) is capable of tracking equipment and staff by work orders, assisting in the
planning and prioritizing of O &M work based on past activity, and maintaining accurate work order and
other maintenance documentation used in collection system analysis and reporting. The CMMS is also
GIS compatible. The CMMS is the central location for asset history, work orders, and labor hours. The
WRD is currently replacing the Hansen CMMS system with a new, modern system provided by
MentorAPM that would increase functionality, including tracking vertical assets, asset age, performance,
and criticality impacts.
4.2.2 Gravity Sewers
The Wastewater team clean all City-owned sewer pipes between 4-72 inches in diameter. The schedule
of cleaning can be every 2 months, 4 months, 6 months, yearly, and every 3-5 years, depending on the
condition of the line, operating history, and service area characteristics. The priority is to clean those
lines that have a history of blockage or SSOs. Portions of the collection system with repeated SSOs are
evaluated for immediate replacement or prioritization as part of the City’s Capital Improvement
Program (CIP), depending on the specific conditions present in the line.

The Wastewater team utilizes a hydro jetting truck and combo unit trucks to flush and jet sewer lines.
One complete video-capable truck is available for immediate deployment 24 hours per day, and routine
main jetting is conducted 5 days a week.
High frequency cleaning occurs in those areas that are known to have many food service establishments
(FSEs) that generate FOG and those areas that are known to suffer from persistent root intrusion. These
areas are maintained every 2-4 months. Lines that are larger than 15 inches are scheduled to be cleaned
at least biennially.
Historical line cleaning results are provided in Table 4-1. Line connections and manholes are inspected at
the time of cleaning. Any issues noted during the inspection are scheduled for repair. Either the City or a
hired contractor conducts any repairs.

4.2.3 Closed Circuit Television (CCTV) Inspections
The City conducts system-wide routine preventative maintenance activities, including closed circuit
television (CCTV) reconnaissance of its collection system, utilizing experienced dedicated O &M staff to
ensure efficient and reliable operation of the various components of the sewer system.
One complete video-capable truck is available for immediate deployment 24 hours per day, and routine
main jetting is conducted 5 days a week. The priority is to clean those lines that have a history of
blockage or SSOs. Portions of the collection system with repeated SSOs are evaluated for immediate
replacement or prioritization as part of the City’s CIP, depending on the specific conditions present.

The City previously utilized WinCam software for facilitating CCTV activities. Presently, Granite Net will
be the new provider for the City’s CCTV program. The City anticipates being able to CCTV every line in
the service area within 3-5 years.
4.3 Rehabilitation and Replacement Program
The City has a long-term program to rehabilitate and replace lines in the system that may be deficient.
The program has prioritized portions of the sewer system that have persistent issues, older line segments,
and upsizing lines that are 6 inches. This work is included in the City’s CIP process. CIPs are approved
biannually. On average, the City replaces 1-2 miles of sewer pipes each year.
4.4 Training
The City encourages, and requires staff, to obtain professional certifications or licenses (e.g., California
Water Environment Association). WRD staff receives training on a regular basis in sewer system O&M
developments and techniques, and in work safety topics. In addition, many WRD staff maintains various
professional certifications through related continuing education or professional participation credits.
Confined space training
4.5 Equipment and Replacement Parts
Critical equipment and replacement part inventories are maintained at the City Maintenance Yard (Yards)
Complex, located at 2500 Michigan Avenue in Santa Monica. Mechanical equipment and WRD trucks and
support vehicles are fueled, serviced and repaired at the Yards, and many of the administrative functions
related to the collection system are also housed in this central location.

a. Design and construction standards and specifications for the installation of new sanitary sewer
systems, lift stations and other appurtenances; and for the rehabilitation and repair of existing
sanitary sewer systems; and
b. Procedures and standards for inspecting and testing the installation of new sewers, pumps, and
other appurtenances and for rehabilitation and repair projects.
5.1 Design Criteria for Installation, Replacement, and Repair
Sanitary sewer system design standards, Standard Specifications, and Standard Plans are maintained by
the Civil Engineering Division of the Public Works Department. These plans extend to sewer mainlines,
structures, structures and appurtenances like manholes, lift stations, and service laterals.
5.1.1 General
The City has standards established for new construction, replacement, and renewal regarding any work
on the collections system. There is a periodic review of these standards by the Engineering Division. The
last update was done in 2021. The most up-to-date version of Standards is available at the City website.
Please see the link below.
Specifications subject to inspection during construction are Construction Standards Institute (CSI) based
and are modified as applicable by the Standard Specifications for Public Works Construction
(GREENBOOK), latest edition, which is jointly produced by representatives of the American Public Works
Association (APWA), the Associated General Contractors of California, the Engineering Contractors
Association, the Southern California Contractors Association and BNi Publications, Inc.
Complete versions of the City’s Standards Specifications and Standard Plans are located at the City
website. Please click through to:
https://www.santamonica.gov/standard-detail-and-specifications
5.1.2 Moss Avenue Pump Station
MAPS is a sewer pump station owned by the City. MAPS is a critical component of the Coastal Interceptor
System (CIS), which moves sewage along the coast from northern Los Angeles, through Santa Monica, and
eventually to the Hyperion Treatment Plant. MAPS is the City’s single most critical sewer utility asset as it
is in very close proximity to the Santa Monica Pier.
The pump station is equipped with two discharge force mains. To-date, this pump station has
predominantly used a single force main for all discharge. Utilizing both force mains, MAPS’ firm capacity
(three duty pumps running) has been field measured at 27.6 MGD discharging through a dual force main

configuration. The maximum capacity (four pumps running) has been field measured as 36.9 MGD
discharging through dual force mains as per the MAPS Evaluation Report 2015.
Detailed information for the MAPS, junction boxes, gauging stations and siphons was obtained from
Operations and Maintenance and As-Built Drawings.
5.1.3 Authorized Pipe Materials
The City currently requires polyvinyl chloride pipe as the standard for authorized pipe material.
Specifically, PVC SDR-26 is the type called out for usage in the City. For any pipe lining, cured-in-place-pipe
(CIPP) is required.
5.1.4 Private Sewer Systems and Laterals
All private sewer systems and private sewer laterals are required to be design, installed, inspected and
accepted per the Green Book and the City Adaptations to the Green Book. Private sewer laterals must
also conform to the requirements of the California Plumbing Code.
5.2 Inspection and Testing Criteria
Wastewater construction inspection and testing criteria is based on the Green Book. Standards and
specifications are reviewed before any job is put out to bid. Any additional technical requirements will be
called out and added to any specific construction project. This criteria applies to new and rehabilitated
gravity sewers and new and rehabilitated manholes.
These standards, which are based on Standard Specifications for Public Works Construction, are updated
as required by CSMWRD staff and are made available to the public by the Civil Engineering Division upon
request so that all engineering contractors and civil engineers are aware of the CSMWRD’s standards for
wastewater construction. Presently, City wastewater projects are designed by the Civil Engineering
Division within the City, and each project’s contract documents contain all wastewater specification
standards, construction notes and details for the project. They are modified to be site-specific on a
project-by-project basis. Contract documents are prepared in-house using consultant civil engineers for
the plans and technical specifications.
Typically, because of historic development within the City, there are unique construction challenges
presented by interfering utilities and confined rights-of-way, which require site or project specific
modifications to existing standards. In those cases, the City usually depends upon construction applicants’
private engineers to modify or design a new standard and will review and approve it for site-specific
construction.

Element 6 Spill Emergency Response Plan
SWRCB Requirements:
a. Each Enrollee shall develop and implement an Spill Emergency Response Plan (SERP) that
identifies measures to protect public health and the environment. At a minimum, this plan must
include the following:
b. Proper notification procedures so that the primary responders and regulatory agencies are
informed of all SSOs in a timely manner;
c. A program to ensure an appropriate response to all overflows;
d. 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 SSOs that potentially affect public health or reach the waters of the State in accordance with
the Monitoring and Reporting Program (MRP). All SSOs shall be reported in accordance with this
MRP, the California Water Code, other State Law, and other applicable Regional Water Board
WDRs or NPDES permit requirements. The SSMP should identify the officials who will receive
immediate notification;
e. Procedures to ensure that appropriate staff and contractor personnel are aware of and follow the
Emergency Response Plan and are appropriately trained;
f. Procedures to address emergency operations, such as traffic and crowd control and other
necessary response activities; and
g. 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 SSOs, including such
accelerated or additional monitoring as may be necessary to determine the nature and impact of
the discharge.
6.1 Purpose
The City’s SERP serves as a guide for efficiently and appropriately responding to sewer spills. The SERP
has directions for staff to follow regarding response, cleanup, and reporting of any sewer spills in the
City’s service area.
6.2 Sanitary Sewer Overflow Emergency Response Plan
An SSO is any overflow, spill, release, discharge, or uncontrolled diversion of untreated or partially treated
wastewater from a sanitary sewer. SSOs may contain high levels of suspended solids, pathogenic
organisms, toxic pollutants, nutrients and oil and grease and can adversely impact human health and the
environment. In order to minimize the potential for health and environmental impacts, the City has
developed the following plan and standard operation procedure (SOP) for responding to all SSOs.
5.C.c
Packet Pg. 193 Attachment: Draft Sewer System Management Plan Update 2023 (5683 : Sanitary Sewer Management Plan)
SEWER SYSTEM MANAGEMENT PLAN 2023
CSMWRD SSMP Overflow Emergency Response Plan Element 6 Page 6-2
SSO Emergency Response Plan:
City water resources and inspection staff have been trained to respond promptly upon receiving
notification of an uncontrolled sewage discharge. An SSO can originate from residential structures,
commercial facilities, or City related devices, (e.g., broken sewer lines, and/ or manhole covers). Time is
of the essence in responding to SSO incidents to control and reduce the potential for impact to the storm
drain system and waters of the State.
The SSO plan involves two basic steps.
Step# 1- Upon notification, City Wastewater staff (both Operations and Water Resources
Protection Program (WRPP) inspector) responds and identifies the location of the overflow and
its characteristics (i.e., apparent source, volume released, extent, and whether it is on private
property etc.). They also determine the potential cause of the SSO and the responsible party. This
information is recorded on the SSO Response Form. To ensure containment, CSM Wastewater
Staff locate the nearest down gradient (down slope) storm drain and determine if the release has,
or will, reach this drain. Based on site conditions, the onsite incident manager decides if
immediate action or additional staff or equipment is needed to prevent the release from reaching
this drain. If the SSO occurred because of a blockage at a main City sewer line, the onsite incident
manager will direct CSM Wastewater Staff to immediately contain the discharge by completely
berming the storm drain inlet and to clear the blockage. Once the nature and extent of the
discharge are known, staff will begin immediate cleanup of discharges caused by a city-owned
pipeline; typically by vacuuming the discharge for lawful disposal.
Staff also ensures the release area (all public areas) are cleaned and disinfected after the normal
sewer flow is restored and the blockage relieved. If the release has reached the storm drain
system, staff will routinely check a couple of storm drain catch basins downstream from the
contaminated catch basin to verify how far the release has traveled down the storm drain line.
Depending on the severity of the release, samples may be required to be taken from those catch
basins and analyzed for pathogenic organisms. Sampling, if any, conforms to steps taken in the
City’s Water Quality Management Plan (WQMP).
If a release from a City-owned main has visibly impacted private property, the onsite staff will
photo document all such impacts identified at the time of the release response. Staff also
documents the contact information of the property owner and any notes regarding the potential
impact in their field notebook. Questions regarding repair costs are directed to the CSM Office
of Risk Management at (310) 458-8910.
Step # 2- If the SSO occurred because of a blockage or other problems within a privately owned
lateral line resulting in a discharge to the ground surface and /or into the public right-of-way such
as City streets, alleys or sidewalks, CSM Wastewater staff will contain and prevent further
discharges into the Public Right- of- Way as described in Step #1, above. This is typically done by
using a City vacuum truck. CSM staff then contact the subject property owner/manager and direct
5.C.c
Packet Pg. 194 Attachment: Draft Sewer System Management Plan Update 2023 (5683 : Sanitary Sewer Management Plan)
SEWER SYSTEM MANAGEMENT PLAN 2023
CSMWRD SSMP Overflow Emergency Response Plan Element 6 Page 6-3
them to immediately contact a private plumber to relieve the sewer blockage. In instances where
there is no effective response from the property owner or manager to abate the SSO within a
reasonable time frame (less than an hour), or at the discretion of the onsite incident manger or
the WRPP Inspector, the water service may be temporarily turned off at the subject property after
proper notifications are made by calling the CSM Water Division staff and requesting a temporary
water service disruption.
Before attempting to turn off the water service, CSM Wastewater Staff will try to contact the
property owner or manager. Wastewater Operations Staff will make notification if a WRPP
Inspector is unavailable (i.e., after hours, weekends). Notification is made verbally and by posting
a large placard in a common area and a door hanger on each unit or residence/ business. Each
placard and door hanger has contact information for the CSM and the Los Angeles County DHS
Public Health. If possible, door hanger notifications are placed on each tenant’s door depending
on access.
Note: The duration, and therefore volume, of the SSO discharge is estimated from when the SSO
is first reported to the City, NOT when staff arrives to the site. Staff are required to accurately
estimate the volume of the discharge and note how the estimate was derived in their field book.
Photographs of the SSO site are also included in the incident file when damage to private property
is known to have occurred.
Other agency contact/reporting include:
- Office of Emergency Services (OES) at (800) 852-7550 to obtain an OES Control#. After
business hours including weekends, CSM Wastewater staff makes the notification to OES and
provides WRPP inspection staff with the OES Control #.
For logistics planning, staff has determined it typically takes 45-60 minutes for a private plumber
to arrive and/ or relieve the sewer blockage on private property. Prior to the arrival of the plumber
if the water is not shut down, City staff ensure that the property owner makes all efforts to contain
sewer discharges on their property and not allow any discharges onto the public right-of-way.
Any discharge that reaches the public right-of-way will be contained by City staff.
Wastewater Staff monitor the SSO site continuously to make sure the plumbing problem is
corrected and sewage at the site has been cleaned up and the release area is disinfected.
Wastewater Operations Staff will disinfect the impacted street and sidewalk (public areas)
immediately in contact with the release using chlorine/water solution. Large discharges from
private property requiring clean-up will be billed to the property owner for cost recovery of labor
and equipment use. Once the sewer blockage is cleared, and the contaminated area cleaned and
disinfected, the property owner/manager may call and request the Water Division to turn the
water service back on, if needed.
If there is an extensive damage to privately owned properties because of an overflow and release
of sewage due to a SSO, depending on the cause, staff will call or advise the property owner to

directly contact LA County Dept. of Health Services (DHS) at 310-665-8484 to evaluate the health
hazard and recommend detailed procedures for proper clean-up. Staff will also contact the CSM
Office of Risk Management to evaluate any damages if the SSO is caused by blockages or flow
conditions within the publicly owned portion of a sanitary sewer system.
It is important to remember that spills into the City storm drain system from SSO’s typically are
captured by one of the City diversion BMP projects such as SMURFF, Wilshire Blvd., Montana Ave.,
Rose Ave., Ashland Ave., Sunset-Canyon and Centinela-Pearl projects and therefore normally do
not reach Santa Monica Bay as long as those diversion projects are operational at the time of the
incident. Staff will confirm the operational status of the subject BMP project as part of the SSO
response procedures.
Once the SSO response incident is concluded, WRPP Inspection Staff forward the required data to
the California Integrated Water Quality System (CIWQS) by visiting the agency database at:
http://ciwqs.waterboards.ca.gov and entering on-line the requested information about the SSO.
WRPP Inspection Staff also retain a copy of all completed reports about an SSO incident in a folder
designated for SSO records.
SSO Equipment and Training
Typical equipment required for response to an SSO, depending on location and size of the release,
includes, but is not limited to, personal protective gear, reporting forms, traffic control devices such as
cones or barricades, absorbent materials, sampling equipment, disinfectant solutions, pipe snake, vacuum
trucks, backhoe, replacement pipe, and street sweepers.
The City conducts regular training to familiarize staff with health and safety issues, standard response
procedures, and regulatory and technological developments. The City also encourages staff to
recommend more efficient ways of completing work tasks based on staff field experience.
Moss Avenue Pump Station (MAPS) Emergency Response
CSM staff monitors MAPS through SCADA alarm system during and after hours. Upon discovery or
notification of an SSO at the facility, staff would respond to the MAPS to make necessary SSO assessment.
Staff would check the generator, wet well operation, pumps, and force mains. For SSOs that occur because
of MAPS or force mains, notifications to proper regulatory agencies and response procedures apply that
are discussed as part of this SOP.
Specific procedures include:
Wet Well
x Observe SCADA screen and PLC panel to confirm proper wet well level
x If SCADA and PLC not operational, emergency notification to Plant Operator, Supervisor and
Senior WRD staff and SCADA technician.
x Call emergency pump contractor for emergency pump/bypass equipment set-up at facility.

7.3 FOG Control Program
The City has determined that a FOG control program is necessary per SSMP requirements. There are
approximately 474 food service facilities located within City limits and discharge to City sewers.
Operations and maintenance staff have also noted the tendency for grease buildup in specific sewer
lines due to proximity to sources or hydraulic conditions. This section discusses measures the City takes
to control FOG.
The City’s FOG control program consists of focused cleaning and maintenance as well as source control.
The following subsections discuss identification and cleaning of grease-prone areas, legal authority to
prohibit grease discharge or require a grease removal device, facility inspection, and public outreach.
Water Resources Protection Program and Source Control
The City of Santa Monica Water Resources Protection Program (WRPP) facilitates the FOG Source
Control Program and ensures compliance with federal, state, and local regulations for wastewater pre-
treatment standards prior to discharge into the City’s wastewater collection system. WRPP Staff
oversees all industrial and business customers that have the potential to adversely affect the CSM
wastewater system by the issuance of Industrial Wastewater permits every year, inspections, and
applicable unannounced sampling events for approximately 870 businesses requiring pre-treatment
and/or regular monitoring for toxic substances, such as inorganic toxic substances, such as acids &

metals, fats from grease and oil producing food-related operations, and other oil and grease producing
operations, such as automotive uses, prior to connection and discharge to the wastewater system. For
FOG control, there are 474 permittees subject to inspection. For instances of non-compliance with
sewer limitations and prohibited discharge standards as specified in the Santa Monica Municipal Code,
the WRPP relies on various escalating enforcement actions such as the issuance of Notices of Correction
(NOC), Notices of Violation (NOV), administrative citations, and referral to the City Attorney’s office for
prosecution. Every permittee inspection is stored in a Hansen 8 computer database as well as a hard
copy file. WRPP is also in constant contact with CSM Wastewater staff about any significant findings in
the collections system. The WRPP also advises residential customers through outreach information and
in tandem with the City’s Household Hazardous Waste Program, the proper disposal methods for toxic
materials (such as mercury), waste cooking oil, and other household hazardous waste. In addition, the
WRPP has distributed education material on the importance of preventing FOG from entering the
sanitary sewer system and brochures on roots and how they adversely affect the wastewater system to
the residents of Santa Monica. This information is also distributed to residents at the City of Santa
Monica Festival, which is held yearly.
The City also requires the installation of pretreatment devices such as clarifier and grease interceptors
for new and remodeled facilities and requires pretreatment devices to be installed in other older
facilities that have caused SSOs.
The City also has an annual inspection and random sampling program and keeps records of all permits
with proof of regular maintenance of all pretreatment devices by the permit holder.
Wastewater Operations Program
The Wastewater Operations Staff is responsible for the cleaning, monitoring and maintenance of the
City’s wastewater collection system. Maintenance consists of four (4) full-time crews, five to six days a
week jetting and cleaning the local collection system and the CIS. Wastewater Operations also
maintains the City’s Moss Avenue Pumping Station (MAPS), end of line diversions into the sewer system.
The City completed replacing and/or lining 80% of its sewer mains and manholes in 2002. Areas of
concern based previous experience are tracked on the City GIS system and are cleaned more frequently.
Together with the CSM Civil Engineering & Architecture Division problem-prone pipelines having both
structural and flow capacity issues are prioritized for replacement to minimize the potential for serious
SSO incidents.
7.4 GWRD Requirements Response
Requirement (a): An implementation plan and schedule for a public education outreach program that
promotes proper disposal of FOG.
Response: The City regulates FOG through WRPP’s Source Control Program and with regular, proactive
sewer cleaning. Areas that have a high density of FSEs tend to have higher cleaning frequencies. FSEs are
also inspected routinely by WRPP. Finally, public outreach regarding FOG issues is provided for
businesses as well as the general public.

Requirement (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.
Response: There are grease disposal sites available in Los Angeles County that accept spent grease from
nearby commercial disposal companies. The City provides FSEs with a vendor list of California
Registered Inedible Kitchen Grease Commercial Transporters. No vendor is recommended or preferred
by the City.
Requirement (c):The legal authority to prohibit discharges to the system and identify measures to
prevent SSOs and blockages caused by FOG
Response: Santa Monica Municipal Code provides the legal basis for the City’s Source and FOG control
program. This is noted in Element 3. More specifically, SMMC 5.20.110 provides requirements for grease
disposal and FSE BMPs. SMMC 5.20.080 provides requirements for grease interceptor installation.
Requirement (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.
Response: The City’s WRPP team meets this requirement as described in Requirement (c). Also, WRPP
observes FSE BMPs and record keeping during routine inspections.
Requirement (e): Authority to inspect grease producing facilities, enforcement authorities, and
whether the Enrollee has sufficient staff to inspect and enforce the FOG ordinance.
Response: WRPP conducts regular inspections of FSEs and is granted authority to inspect and enforce via
SMMC 5.20.
Requirement (f): An identification of sanitary sewer system sections subject to FOG blockages and
establishment of a cleaning maintenance schedule for each section
Response: The City’s Wastewater team prioritizes areas of high FSE concentration and areas where
there may be high FOG discharger for more frequent cleaning of connected sewer lines. Wastewater is
flexible and will tend to any area that may have become problematic.
Requirement (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.
Response: Similar to the response to (f), WRPP supports the Wastewater team and follows up on those
FSEs that are discharging significant amount of FOG.

Element 8 –Capacity Assurance Plan
SWRCB Requirements:
The Enrollee shall prepare and implement a capital improvement plan (CIP) that will provide hydraulic
capacity of key sanitary sewer system elements for dry weather peak flow conditions, as well as the
appropriate design storm or wet weather event. At a minimum, the plan must include:
a) Evaluation: Actions needed to evaluate those portions of the sanitary sewer system that are
experiencing or contributing to an SSO discharge caused by hydraulic deficiency. The evaluation
must provide estimates of peak flows (including flows from SSOs that escape from the system)
associated with conditions similar to those causing overflow events, estimates of the capacity of
key system components, hydraulic deficiencies (including components of the system with
limiting capacity) and the major sources that contribute to the peak flows associated with
overflow events;
b) Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation
identified in “a” above to establish appropriate design criteria; and
c) Capacity Enhancement Measures: The steps needed to establish a short- and long-term capital
improvement plan (CIP) to address identified hydraulic deficiencies including prioritization,
alternatives analysis, and schedules. The CIP may include increases in pipe size, I/I reduction
programs, increases and redundancy in pumping capacity, and storage facilities. The CIP shall
include an implementation schedule and shall identify sources of funding.
d) Schedule: The Enrollee shall develop a schedule of completion dates for all portions of the
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.

8.1.1 System Capacity Evaluation
Evaluation of a sanitary sewer collection system during dry and wet weather conditions involves
evaluation of both capacity and general operational issues. The capacity of the system is primarily
controlled by population and significant commercial/industrial dischargers. Operational issues that may
lead to inadequate level of service system performance include roots, fats, oils and grease. The hydraulic
model is an important utility management tool to assist in identifying locations of capacity constraints or
velocity concerns that may exist in the existing system or are projected to arise under future dry or
weather flows.
Depth of flow in relation to pipe diameter, or depth-to-diameter (d/D) ratio is an element of the City’s
existing design criteria and is used herein to identify potential capacity problems within the system,
which may result in sewer overflows. A wet weather assessment of the sanitary sewer system is focused
on the elimination of wet weather overflows for a particular design storm event. Design storms are
primarily defined by their duration and the return period. Duration is the amount of time over which a
rain event occurs, where the return period is a measurement of the likelihood a particular event will
5.C.c
Packet Pg. 204 Attachment: Draft Sewer System Management Plan Update 2023 (5683 : Sanitary Sewer Management Plan)

WRD SSMP Capacity Assurance Plan Element 8 Page 8-2
occur. For example, a 5-year storm will theoretically occur once every 5 years. Since the selection of the
design storm can have a significant impact on determining the adequacy of system capacity, this design
criteria driven level of service element of the Sanitary Sewer Master Plan had careful consideration in
this planning effort. Based on discussions with City staff, the design storm selected to be incorporated in
the hydraulic model simulation is a 10-year 24-hour event. This design criterion is also used by City of
Los Angeles, the regional wastewater conveyance and treatment provider, in the assessment of its
sewer system hydraulic capacity analysis programs to contain peak wet weather flows in the sewer
design to avoid SSOs.
8.1.2 Existing Conditions Collection System Evaluation
The purpose of a sanitary sewer system is to collect sewer flow from various origins in the City and
convey these flows to a designated point of discharge. The maximum and minimum flow rates in any
given day can vary, but generally follow some typical daily diurnal patterns for residential and non-
residential customers. The sanitary sewer system should be designed to carry the maximum rate within
an acceptable range of velocity without the sewer system backing up during these peak daily flows. In
contrast, the sewer system should also have adequate flows and velocity to convey the minimum flow
without deposition of suspended solids during the minimum daily time periods, which is typically in the
middle of the night. The City’s hydraulic model was developed to effectively simulate the system’s
hydraulic behavior at specific time period and analyze its performance under various flow conditions.
The InfoSewer model uses steady-state simulations in its hydraulic analysis calculations for the analysis
of utility sewer systems. For a steady-state analysis, all flows are assumed to accumulate in the system
and discharge only at the outlets. This means that even if a pipe has a flow beyond its maximum
capacity, the flow is still carried downstream including through pumps and force mains so that
full/maximum flow conditions are carried through to all affected downstream facilities. The transition
between gravity flow and pressurized flow is also ensured by assuming that all flows are transported
through each force main, subject to the upstream hydraulic control. The hydraulic evaluation of the
City’s existing collection system was performed using the collection system model developed as
described earlier and is explained in this section.
The existing system evaluation applies current sewage flows to applicable spatial locations in the system
and incorporates current infrastructure configurations and applicable operational strategies, typically
associated with pump stations, force mains and diversion structures. A sanitary sewer collection system
has basically two main functions: to convey the designed peak discharge and to transport solids so that
deposits are kept to a minimum. It is imperative; therefore, that the sanitary sewer has adequate
capacity for the peak flow and that it functions at minimum flows without excessive maintenance and
odor generation. The existing system scenario takes into consideration the current flows in the existing
infrastructure, both under dry and wet weather conditions. The existing scenario incorporates all
facilities in the existing sanitary sewer system including gravity mains 10-inch in diameter and greater
(and all 8-inch mains directly upstream from 10-inch mains), maintenance holes, lift stations, pumps,
force mains, and the outfall station located at SM-1. For the dry weather scenario, sewer flows are
loaded to each node in the system based on the summation of account-level tributary sewer flows, as
5.C.c
Packet Pg. 205 Attachment: Draft Sewer System Management Plan Update 2023 (5683 : Sanitary Sewer Management Plan)
SEWER SYSTEM MANAGEMENT PLAN 2023
WRD SSMP Capacity Assurance Plan Element 8 Page 8-3
derived from water consumption data. To simulate wet weather conditions stemming from infiltration
and inflow, a peaking factor (PF) was applied to the dry weather loads at all nodes in the sewer system
network. This wet weather PF is calculated as the ratio between the average day flows and the flows
that occur on the day out of the year when the highest flows are recorded during a particular wet
weather event.
An understanding of the hydraulic condition of the existing system is essential to identify existing system
related capacity limitations and to help prioritize recommended system improvements resulting from
the ultimate system capacity analysis. The InfoSewer hydraulic model developed as a part of the Sewer
Master Plan was used to perform the capacity analysis of the existing collection system. The capacity
analysis was performed for various existing flow scenarios including existing average, peak dry weather,
and peak wet weather flow scenarios. Improvements are identified based on the evaluation of the
existing system during the peak hours of wet weather conditions. The capacity analysis performed
herein is consistent with generally accepted methods and is based on the consideration of the depth of
flow with respect to the diameter of the pipe. A capacity limited section along a pipeline is identified as
a potential capacity related improvement project if the depth to diameter (d/D) ratio exceeds the
criteria established to define system performance during the designated wet weather flow scenario
conditions. The hydraulic model constructed for this study was used to evaluate performance of the
collection system using the criteria for d/D ratio and velocity for gravity pipes, and surcharge depth for
maintenance holes. Under existing dry and wet weather flow conditions, a large majority of the City’s
sewer collection system pipelines have excess or reserve capacity. The existing hydraulic modeling
simulation identified approximately 1 percent of the total sanitary sewer pipeline system had d/D ratios
greater than the 0.75 criteria. This finding indicates the City’s sewer system has available capacity in
much of the local sewer system.
8.1.3 Background of InfoSewer Software Modeling
The City’s sanitary sewer collection system was modeled using the InfoSewer Version 7.6 software by
Innovyze. The InfoSewer software can simulate all aspects of the City’s sanitary sewer collection system
through a hydraulic model network. A hydraulic model network is a mathematical representation of the
collection system represented by a series of nodes and links. Nodes represent maintenance holes,
storage basins, wet wells, junction boxes, and outfalls. Links, as the name implies, represent any
hydraulic structure connecting two nodes. Sanitary sewer pipelines, force mains, lift stations, weirs, and
gates are all represented by links in this model. During the conduct of hydraulic simulations, the model
considers the available storage at these hydraulic elements (through filling and draining) and can
simulate unsteady state flow conditions under both open channel and surcharged conditions for varying
time periods. Additionally, this model allows simulation of single path and multiple path flow networks,
backwater curves, flow reversals, pumps, weirs, siphons, gates, orifices, parallel pipes, and other
diversion structures necessary to simulate a sanitary sewer system, such as the City's.

8.2 Design Criteria
The City’s wastewater construction standards are maintained by the Engineering Division of the Public
Works Department. These standards are updated as required by City staff and are made available to the
public by the Civil Engineering Division upon request so that all engineering contractors and civil
engineers are aware of the City’s standards for wastewater construction. Presently, public wastewater
projects are designed by the Civil Engineering Division and each project’s contract documents contain all
wastewater specification standards, construction notes and details for the project. They are modified to
be site-specific on a project-by-project basis. Contract documents are prepared in-house using
consultant civil engineers for the plans and technical specifications. Specifications are Construction
Standards Institute (CSI) based and are modified as applicable by the Standard Specifications for Public
Works Construction (GREENBOOK), latest edition, which is jointly produced by representatives of the
American Public Works Association (APWA), the Associated General Contractors of California, the
Engineering Contractors Association, the Southern California Contractors Association and BNi
Publications, Inc.
8.3 Capital Improvement Goals and Schedules
As part of the City’s collection system CIP, land use and flow modeling are utilized to develop and prioritize
five-year and 30-year CIP goals and schedules for consideration and approval by the City Council. The
approved CIP projects are implemented as funds become available through a combination of Council-
adopted incremental development financing (for increases in land use), Council-approved rate increases
(for rate payers), and/or Council-approved increased Wastewater Capital Facility Fees.
The City of Santa Monica pays the City of Los Angeles an Amalgamated Sewerage System Facilities Charge
(ASSFC) for upward changes in land use by building permit. Until July 2008, Santa Monica paid Los Angeles
by utilizing the Santa Monica Wastewater Capital Facilities Fee collected at the time of permit issuance.
This has left Santa Monica’s CIP program at the same monetary level and funded through a combination
of rates collected from rate payers and wastewater capital facility fee at building permit issuance or
change of land use.
Currently, the City is on a 100-year sewer line replacement schedule and presently replaces 1 to 2 miles
of sewer per year.
8.3.1 CIP Prioritization Criteria
In addition to the individual prioritization of capacity-related projects, other key factors have been
integrated in the overall prioritization process. While some of these factors may be somewhat external to
the performance of the City’s Wastewater Enterprise, they will influence the timing and potential cost
aspects of the program’s implementation and have an influence on the level of community disruption and
overall quality of life in Santa Monica. These implementation elements include spatial demand triggers
that link to CIP requirements and associated development projects, inclusion of a broader infrastructure
management perspective by coordinating the CIP with other projects (e. g., underground utility and paving
projects) to minimize community disruption, consideration for cost segregation so that growth pays an

Element 9 – Monitoring, Measurement, and Program Modifications
SWRCB Waste Discharge Requirement:
The Enrollee shall:
a. Maintain relevant information that can be used to establish and prioritize appropriate SSMP
activities;
b. Monitor the implementation and, where appropriate, measure the effectiveness of each
element of the SSMP;
c. Assess the success of the PM program;
d. Update program elements, as appropriate, based on monitoring or performance evaluations;
and
e. Identify and illustrate SSO trends, including: frequency, location, and volume.
9.1 Performance Measures
Annual performance indicators that the City will use to measure the health of the wastewater collection
system and the effectiveness of the SSMP are:
x SSOs: Total number, SSO rate, and number for each cause (e.g., roots, grease or FOG-related
blockage, debris, line failure, capacity deficiency, storm flow exceeding design, lift station
failure, or other);
x Total volume of SSOs and volume contained and returned to the system;
x Total volume and percentage of SSO volume that reached surface water; and
x Footage of main lines and percentage of system cleaned annually.
9.2 Monitoring and Measurement
Over the past three years the City’s commitment to asset management and preventative O & M
activities has resulted in fewer FOG related SSO incidents. The City regularly tracks and monitors the
general effectiveness of preventative maintenance measures through work orders/service requests,
number and location of reportable SSO reports, and required annual regulatory reports. Information
collected includes cause and location of stoppages; number, cause, location, and volume of SSOs;
stoppage response time; number and reason for customer complaints; and type of debris found. The
City has selected these certain, specific parameters because they can be documented and compared on
an annual basis in a simple format. In addition, experience has shown that these parameters are
straightforward, quantitative, and are focused on results.
In addition to the City tracking and monitoring measures, all documented SSO events are reported
through the California Integrated Water Quality System (CIWQS) database within the required
timeframe.

SWRCB Waste Discharge Requirement:
As part of the SSMP, 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.
10.1 SSMP Audits
Internal audits will be conducted by Wastewater Division staff with assistance from WRPP on a biannual
(every 2 years) basis to determine the relevance and effectiveness of each element of the SSMP. In
addition to reviewing each element of the SSMP, the audits will also include a review of schedule
progress for measures implemented to correct any identified deficiencies from the prior version. Based
on the findings of the audit process, the SSMP will be updated or modified accordingly. A copy of the
audit report checklist and findings report will be retained in the file. The audit checklist was based on
the City’s knowledge and size of its system, and the number of FOG related SSO’s. The Audit also
incorporates the elements from example self-audits provided by the State Water Resources Control
Boards Enforcement Division.

Element 11 – Communication Program
SWRCB Waste Discharge Requirement:
The Enrollee shall communicate on a regular basis with the public on the development, implementation,
and performance of its SSMP. The communication system shall provide the public the opportunity to
provide input to the Enrollee as the program is developed and implemented.
The Enrollee shall also create a plan of communication with systems that are tributary and/or satellite to
the Enrollee’s sanitary sewer system.
11.1 Communication Program Discussion
The CSM maintains active public outreach and communication efforts with all its customers, the public-
at-large and surrounding agencies to provide timely information on City projects, improvements, and
emergency situations.
Communication outlets range from public meetings and hearings, representation at community groups,
to time-critical posting of signage in emergency situations and updates, posting to the CSM public
website (https://www.santamonica.gov/) and 24-hour telephone reporting systems. Also, part of the
CSM website are links to agenda and minutes from City Council meetings. Additionally, newsletters and
brochures are developed and distributed community-wide and staff regularly meets with other area
agencies. Informational flyers are often included with customer bills to update the rate payers on
system operations, proposed City projects and programs, and the City has public information staff and
inter-governmental management staff to maintain routine contact with news and media outlets in a
timely manner.
11.2 Communication with Satellite Wastewater Collection Systems
The City of Santa Monica communicates regularly with the City of Los Angeles which accepts and treats
flow from the City. The City of Santa Monica and other satellite agencies that have their flow treated by
Los Angeles attend quarterly contract Cities meetings at which treatment plant, collections system and
pretreatment issues are discussed and coordinated.

TITLE: TASK #:
JOB TO BE PERFORMED:
FREQUENCY: As Required
PROCEDURES
The section of the SSMP provides an overview and summary of the City’s emergency response
documents and procedures for sewer overflows.
6.1 Overflow Emergency Response Plan Elements
Pursuant to current regulations, the City has developed and implemented a sanitary sewer overflow
emergency response plan (SSO Plan). The SSO Plan identifies measures to protect public health and the
environment in the event of an overflow and includes the following elements:
x Proper notification procedures so that the primary responders and regulatory agencies are
informed of all SSOs in a timely manner;
x A program to ensure appropriate response to all overflows;
x 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 SSOs that potentially affect public health or reach the waters of the State.
x Procedures to ensure that appropriate staff and contractor personnel are aware of and follow
the SSO Plan and are appropriately trained;
x Procedures to address emergency operations, such as traffic and crowd control and other
necessary response activities; and
x Procedures to ensure that all reasonable steps are taken to contain untreated wastewater and
prevent discharge of untreated wastewater to waters of the United States and minimize or
correct any adverse impact on the environment resulting from the SSOs, including such
accelerated or additional monitoring as may be necessary to determine the nature and impact
of the discharge.
6.2 Sanitary Sewer Overflow Emergency Response Plan
An SSO is any overflow, spill, release, discharge, or uncontrolled diversion of untreated or partially
treated wastewater from a sanitary sewer. SSOs may contain high levels of suspended solids, pathogenic
organisms, toxic pollutants, nutrients and oil and grease and can adversely impact human health and the

environment. In order to minimize the potential for health and environmental impacts, the City has
developed the following plan and standard operation procedure (SOP) for responding to all SSOs.
SSO Emergency Response Plan:
City water resources and inspection staff have been trained to respond promptly upon receiving
notification of an uncontrolled sewage discharge. An SSO can originate from residential
structures, commercial facilities or City related devices, (e.g. broken sewer lines, and/ or
manhole covers). Time is of the essence in responding to SSO incidents in order to control and
reduce the potential for impact to the storm drain system and waters of the State.
The City SOP for responding to typical SSOs is available in hardcopy by request. The SSO plan
involves two basic steps.
Step# 1- Upon notification, City Wastewater staff (both Operations and Water Resources
Protection Program (WRPP) inspector) responds and identifies the location of the overflow and
its characteristics (i.e. apparent source, volume released, extent, and whether or not it is on
private property etc.). They also determine the potential cause of the SSO and the responsible
party. This information is recorded on the SSO Response Form. To ensure containment, CSM
Wastewater Staff locate the nearest down gradient (down slope) storm drain and determine if
the release has, or will, reach this drain. Based on site conditions, the onsite incident manager
decides if immediate action or additional staff or equipment is needed to prevent the release
from reaching this drain. If the SSO occurred because of a blockage at a main City sewer line, the
onsite incident manager will direct CSM Wastewater Staff to immediately contain the discharge
by completely berming the storm drain inlet and to clear the blockage. Once the nature and
extent of the discharge are known, staff will begin immediate cleanup of discharges caused by a
City-owned pipeline; typically by vacuuming the discharge for lawful disposal.
The information collected on the SSO response form along with any other relevant information
is reported by Wastewater Staff to all required outside agencies such as the Office of Emergency
Services, LA County Dept. of Health Services, LA Regional Water Quality Control Board, and if
applicable, LA Co. Flood Control and City of Los Angeles (see below for more detail).
Staff also ensures the release area (all public areas) are cleaned and disinfected after the normal
sewer flow is restored and the blockage relieved. If the release has reached the storm drain
system, staff will routinely check a couple of storm drain catch basins downstream from the
contaminated catch basin to verify how far the release has traveled down the storm drain line.
Depending on the severity of the release, samples may be required to be taken from those catch
basins and analyzed for pathogenic organisms. Sampling, if any, is implemented at the discretion

of the Water Resources Protection Program (WRPP) Inspector on site, and is based on site
specific observations. If there is a question about the necessity for sampling, onsite staff confers
with the WRPP supervisor on duty. All WRPP Inspector staff have basic sampling equipment
available as part of their standard response equipment.
If a release from a City-owned main has visibly impacted private property, the onsite staff will
photo document all such impacts identified at the time of the release response. Staff also
documents the contact information of the property owner and any notes regarding the
potential impact in their field notebook. Questions regarding repair costs are directed to the
CSM Office of Risk Management at (310) 458-8910.
Step # 2- If the SSO occurred because of a blockage or other problems within a privately owned
lateral line resulting in a discharge to the ground surface and /or into the public right-of-way
such as City streets, alleys or side-walks, CSM Wastewater staff will contain and prevent further
discharges into the Public Right- of- Way as described in Step #1, above. This is typically done by
using a City vacuum truck. CSM staff then contact the subject property owner/manager and
direct them to immediately contact a private plumber to relieve the sewer blockage. In
instances where there is no effective response from the property owner or manager to abate
the SSO within a reasonable time frame (less than an hour), or at the discretion of the onsite
incident manger or the WRPP Inspector, the water service may be temporarily turned off at the
subject property after proper notifications are made by calling the CSM Water Division staff and
requesting a temporary water service disruption.
Before attempting to turn off the water service, CSM Wastewater Staff will try to contact the
property owner or manager. Wastewater Operations Staff will make notification if a WRPP
Inspector is unavailable (i.e. after hours, weekends). Notification is made verbally and by
posting a large placard in a common area and a door hanger on each unit or residence/
business. Each placard and door hanger has contact information for the CSM and the Los
Angeles County DHS Public Health. If possible, door hanger notifications are placed on each
tenant’s door depending on access.
Note: The duration, and therefore volume, of the SSO discharge is estimated from when the SSO
is first reported to the City, NOT when staff arrives to the site. Staff are required to accurately
estimate the volume of the discharge and note how the estimate was derived in their field book.
Photographs of the SSO site are also included in the incident file when damage to private
property is known to have occurred.
Other agency contact/reporting contacts include:

- Office of Emergency Services (OES) at (800) 852-7550 to obtain an OES Control#. After
business hours including weekends, CSM Wastewater staff makes the notification to OES and
provides WRPP inspection staff with the OES Control #.
- LA County Dept. of Health Services at (213) 974-1234 and obtain a ticket #. After business
hours including weekends, CSM Wastewater staff contact the agency and provide WRPP
inspection staff with the incident ticket#.
- Los Angeles County Department of Health Services (DHS) “Public Health” at 310-665-8484
(8:00am-5:00pm) to respond if sewage has been released at private properties. After business
hours including weekends Wastewater Staff call the Los Angeles County Department of Health
Services at (213) 974-1234. Los Angeles County DHS will direct clean-up of private property
outside surfaces i.e. grass, sidewalk, and patio areas. Wastewater staff does not perform clean
up services on private property and therefore the clean-up is the responsibility of the property
owner.
- LA Regional Water Quality Control Board at (213) 576-6657. The Contact is Augustine Anijielo
who may also be e-mailed at aanijielo@waterboards.ca.gov. After hours including weekends,
Wastewater Staff will notify the agency.
-For sewer discharges into the County of Los Angles Flood Control storm drain system, call 24/7
dispatch – 1-800-675-4357. For Sewer discharges into the City of Los Angeles storm drain
system, call 1-800-974-9794. WRPP inspection staff calls in incidents during regular work hours.
Wastewater Staff makes this call during after hours, including weekends.
-For a significant spill (i.e. a spill that would bypass treatment and/or enter Santa Monica Bay)
the Recreational Waters Program at (626) 430-5360 is also contacted.
-For a significant spill into Ashland or Rose Diversions the contact is:
x Jared Deck at (562) 861-0316
x Mike Stephenson: (323) 776-7610
During weekends and after hours: Dispatch: (800) 675-4357
For logistics planning, staff has determined it typically takes 45-60 minutes for a private plumber
to arrive and/ or relieve the sewer blockage on private property. Prior to the arrival of the
plumber if the water is not shut down, City staff ensure that the property owner makes all
efforts to contain sewer discharges on their property and not allow any discharges onto the

Public Right-of- Way. Any discharge that reaches the public right-of-way will be contained by
City staff.
Wastewater Staff monitor the SSO site continuously to make sure the plumbing problem is
corrected and sewage at the site has been cleaned up and the release area is disinfected.
Wastewater Operations Staff will disinfect the affected City street and sidewalk (public areas)
immediately in contact with the release using chlorine/water solution. Large discharges from
private property requiring clean-up will be billed to the property owner for cost recovery of
labor and equipment use. Once the sewer blockage is cleared, and the contaminated area
cleaned and disinfected, the property owner/manager may call and request the Water Division
to turn the water service back on, if needed.
If there is an extensive damage to privately owned properties because of an overflow and
release of sewage due to a SSO, depending on the cause, staff will call or advise the property
owner to contact directly LA County Dept. of Health Services (DHS) at 310-665-8484 to evaluate
the health hazard and recommend detailed procedures for proper clean-up. Staff will also
contact the CSM Office of Risk Management to evaluate any damages if the SSO is caused by
blockages or flow conditions within the publicly owned portion of a sanitary sewer system.
It is important to remember that discharges into the City storm drain system from SSO’s
typically are captured by one of the City diversion BMP projects such as SMURFF, Wilshire Blvd.,
Montana Ave., Rose Ave., Ashland Ave., Sunset-Canyon and Centinela-Pearl projects and
therefore normally do not reach Santa Monica Bay as long as those diversion projects are
operational at the time of the incident. Staff will confirm the operational status of the subject
BMP project as part of the SSO response procedures.
Once the SSO response incident is concluded, WRPP Inspection Staff forward the required data
to the California Integrated Water Quality System (CIWQS) by visiting the agency database at:
http://ciwqs.waterboards.ca.gov and entering on-line the requested information about the SSO.
WRPP Inspection Staff also retain a copy of all completed reports about an SSO incident in a
folder designated for SSO records.
SSO Equipment and Training
Typical equipment required for response to an SSO, depending on location and size of the
release, includes, but is not limited to, personal protective gear, reporting forms, traffic control
devices such as cones or barricades, absorbent materials, sampling equipment, disinfectant
solutions, pipe snake, vacuum trucks, backhoe, replacement pipe, and street sweepers.

WATER QUALITY MONITORING PLAN
CSMWRD WATER QUALITY MONITORING PLAN Page 1
SECTION 1.0: GENERAL SAMPLING PROCEDURES
This section provides basic procedures for wastewater sampling used for assessing inspection,
compliance, and for monitoring the quality of sewage flows in City sewer main lines or accidental
discharges to the ocean or other surface water (i.e. SSOs) with a volume of 50,000 gallons or more. The
procedures outlined here are based on the U.S. EPA sampling procedures titled: Operating Procedure
Number SESDPROC-306-R2. It is important to remember that the monitoring at the City’s outfalls ONLY
needs to be implemented if the City’s diversions are not working AND the discharge (single event)
exceeds 50,000 gallons. If the diversions are working, all discharges will either be diverted to the
Hyperion Treatment Plant or to the City’s SMURRF treatment plant. In these cases, there would be NO
discharge to surface waters or the ocean. All water quality sampling will be conducted by Water
Resources Protection Programs (WRPP) staff unless after hours or in the event of a City-wide
emergency.
In the unlikely event that an SSO or sewer break occurs and the release volume to the storm drain is
50,000 gallons or more and none of the City’s diversion structures are operable, grab samples for water
quality will be collected at the appropriate storm drain outfall to receiving waters (i.e. the ocean). There
are seven drainage areas in the City that have outfalls at the beach, each with their own City or County
operated diversion structure. These drainage area outfalls include:
x Montana Outfall
x Wilshire Outfall
x Santa Monica Pier Outfall,
x Pico-Kenter Outfall,
x Ashland Outfall,
x Rose Outfall, and
x Sunset Canyon Outfall
x Westside Water Quality BMP (filters flows).
A figure showing the location of outfalls within City boundaries is provided in the Element 13 Appendix.
Sampling of subject discharges at the Sunset Canyon or Rose Outfalls will be coordinated with LA
County.
1.1 – Standard Sampling Equipment
At a minimum, the following list of equipment should be on hand for typical wastewater sampling
activities. Because all sampling is site specific, it is important that knowledge of the site or file
5.C.c
Packet Pg. 330 Attachment: Draft Sewer System Management Plan Update 2023 (5683 : Sanitary Sewer Management Plan)
WATER QUALITY MONITORING PLAN
CSMWRD WATER QUALITY MONITORING PLAN Page 2
information be utilized to ensure any necessary specialized equipment is also identified and added to
this basic list. Typical sampling equipment includes:
x Chain-of-custody (COC) forms
x Gas monitor
x Clean Stainless-Steel Sampling Bailer With Chain
x Clean Teflon Beakerവfor transferring liquid to sample bottles
x Cooler with double-bagged ice or “blue ice” വ to maintain sample temperature at approximately
6C
x pH Meter and pH Paper
x Thermometer
x Appropriate Laboratory Cleaned Sample Bottles with applicable preservativesവbe sure to have
spares for selected key analytes in case of field breakage.
x Distilled Waterവfor small volume field decontamination of sampling equipment or person
x Personal Protective Equipment (PPE)വgoggles, gloves, steel toe shoes, safety vest and hard hat
x Gallon-size Plastic Bagsവfor sample bottles
x Plastic Garbage Bagsവfor sampling waste-e.g. used PPE, etc.
x Traffic Control Equipmentവcones/delineators, caution tape
x Sledgehammer and Pickവfor opening manholes
x Digital Camera(charged batteries)
x Cell phone
x Paper Towels
1.2 – Parameters Field Measurements
During sampling, parameters such as temperature, pH, and EC may be measured in the field. Water
quality measurements and instrument calibration details will be recorded in field books and in sampling
notebooks.
1.2.1 – Field Equipment Calibration
To ensure that data are representative of the actual field conditions, field equipment will be routinely
calibrated. For each calibration, the time and date of the procedure, equipment identification number,
the calibration procedure and type of standards used will be recorded on field forms and in notebooks
accompanying the equipment.
5.C.c
Packet Pg. 331 Attachment: Draft Sewer System Management Plan Update 2023 (5683 : Sanitary Sewer Management Plan)
WATER QUALITY MONITORING PLAN
CSMWRD WATER QUALITY MONITORING PLAN Page 3
1.2.2 – Temperature Measurements
Temperature measurements will be made with a mercury-filled thermometer or an electronic
thermistor, and all measurements will be recorded in degrees Fahrenheit.
1.2.3 – pH Measurement
The pH measurement will be made as soon as possible after collection of the sample, generally within a
few minutes. The pH will be measured by immersing the pH probe into an aliquot of the sample. The
pH meter will be calibrated per manufacturer specifications. Two buffer solutions (either pH-4 and pH-
7, or pH-7 and pH-10, whichever most closely bracket the anticipated range of sample conditions) will be
used for instrument calibration.
1.2.4 – Specific Electrical Conductance (EC) Measurement
In the event EC parameters are necessary, the EC will be measured by immersing the conductivity probe
into an aliquot of the sample. The probes used should automatically compensate for the temperature of
the sample. Measurements will be reported in units of micro-Siemens (µS) per square centimeter
(equivalent to micromhos or µmhos) at 25 degrees Celsius (77 degrees Fahrenheit).
The EC meter will be calibrated in accordance with the equipment manufacturer’s specifications and as
outlined in the instruction manual for the EC meter used. The EC meter will be calibrated with a
standard potassium chloride (KCl) solution recommended by the instrument manufacturer.
1.3 – Safety
Proper safety procedures must be observed at all times when collecting wastewater/water samples. It
is incumbent on the sampling staff to be aware of potential hazards that may be encountered, and any
special safety conditions (e.g. traffic, confined space, etc.) before planning or implementing the field
sampling activity. Independent sampling consultants working for the City’s Water Resources Protection
Programs (WRPP) must have a site specific Health and Safety Plan (HASP) signed by a Certified Industrial
Hygienist or other qualified professional. Sampling conducted by WRPP staff shall be pursuant to all
relevant, applicable and most current City health and safety plan (HASP) guidelines.
1.4 – General Sampling Precautions
In order to collect representative and defensible data, field sampling must be conducted with a defined
goal in mind (e.g. is the data for compliance, scheduled monitoring, or an enforcement action), and be
conducted in an organized and repeatable fashion. Some general sampling precautions are:
5.C.c
Packet Pg. 332 Attachment: Draft Sewer System Management Plan Update 2023 (5683 : Sanitary Sewer Management Plan)
WATER QUALITY MONITORING PLAN
CSMWRD WATER QUALITY MONITORING PLAN Page 4
x Store samples in a clean secure location in order to avoid contamination.
x Do not overflow bottles that contain preservatives while sampling.
x Maintain proper custody procedures at all times (i.e. do not leave samples unattended).
x Document all field activities in ink in a field notebook.
x To the extent possible, sample collection should progress from the least contaminated location
to the most contaminated location in order to minimize the potential for significant cross-
contamination from sampling equipment.
x If possible, segregate suspected high level contamination samples while storing and transporting
from those with potentially lower levels of contamination.
x Always use a new pair of clean gloves for each sample location.
x Always use new laboratory-cleaned sample bottles.
x Always strictly observe laboratory sample preservative requirements and analytical method
holding times.
1.5 – General Sampling Considerations
Because field, operational, or sampling conditions usually vary from one site to the next, the complexity
of sampling at a particular site can also be markedly different from another. Key to any sample activity
considerations are the specific pollutant limitations for the CSM. These can be found in CSM Municipal
Code Section 5.20.040. In addition, the most recent bacterial Total Maximum Daily Load (TMDL) for
Santa Monica Bay (receiving waters for our outfalls) is also relevant and applicable.
1.6 – Water Quality Samples
Grab samples will be collected to assess the water quality. The sampler will wear clean chemically
resistant gloves as specified in the HASP while collecting the sample. Samples will be collected directly
from the sampling device into laboratory-prepared bottles. Gloves will be changed at each individual
sample location.
If known, each sampling episode should generally begin with the location having the lowest
concentration of target compounds. Successive samples should generally be sampled in sequence of
increasing concentration. Field QA/QC samples including equipment blanks, field blanks, trip blanks,
and duplicates will be collected as necessary during each sampling event.
If a bladder pump or electric submersible pump is being used to sample, the flow rate will be adjusted to
1) approximately 100 milliliters per minute (mL/min); 2) a rate specifically selected based on discharge
flow rates; or 3) as low as possible. This rate will be maintained until the discharge line has been purged
and the sample collected.
5.C.c
Packet Pg. 333 Attachment: Draft Sewer System Management Plan Update 2023 (5683 : Sanitary Sewer Management Plan)
WATER QUALITY MONITORING PLAN
CSMWRD WATER QUALITY MONITORING PLAN Page 5
All samples will be sent to a State-certified testing laboratory for analysis. Sample analysis will, at
minimum, include the following methodologies:
x All outfall samples will be tested for Fecal Coliform by Method SM 9221B, Total Coliform by
Method SM 9221E, Enterococcus and Fecal Streptococcus by Method SM 9230B, and in situ pH
and field temperature.
x Additional analytes may be added based on knowledge of the discharge source.
1.7 വ Sample Containers and Preservation
Appropriate pre-cleaned sample containers and preservatives for the analyses to be performed will be
obtained from the subcontracted analytical laboratory. Appropriate sample containers, volumes,
preservation, and holding time requirements are prioritized on Table 1 located in the Element 13
Appendix.
1.8 വ Sample Labeling
Sample containers will be labeled before or immediately after sampling with self-adhesive tags having
the following information written in waterproof ink:
x Project number;
x Sample identification number (unique);
x Date and time sample was collected;
x Initials of sample collector; and
x Preservatives used
1.9 വ Quality Control Samples
To evaluate the precision and accuracy of analytical data, quality control samples, such as duplicates and
blanks, will be periodically collected and/or prepared (e.g. one per location). These samples will be
analyzed for the same analytes using unique (i.e. blind) sample identification number.
1.10 വ Sample Handling, Storage, and Transportation
Efforts will be made to handle, store, and transport supplies and samples safely. Exposure to dust,
direct sunlight, high temperature, adverse weather conditions, and possible contamination will be
avoided. Immediately following collection, sample bottles will be sealed within a Ziploc bag and placed
in a clean chest that contains ice (if cooling is required), and will be transported to the subcontracted
laboratory as soon as practical. Samples may only be held in the dedicated sample refrigerator at the
WRPP offices.

CSMWRD WATER QUALITY MONITORING PLAN Page 6
2.0 – Field Activity Documentation
The WRPP and Wastewater Division maintain all of its analytical data in an automated data system. In
order to maximize the efficiency and accuracy of the data system, all laboratory data is transmitted from
the laboratory to the WRRP in an electronic format (WRPP will handle all lab interactions). The
responsible party on the COC will receive a copy of the data (including the accompanying COC) in a PDF
format. The PDF format provides certainty that the data has not been altered after being generated by
the laboratory. Another copy of the data is transmitted directly to the WRPP/Wastewater Division
information and technology manager for direct downloading into the data system. It is recommended
that if the PDF format is retained, that it be disposed of after three years or pursuant to the most
current City document retention guideline. Both the laboratory and the data system will have
possession of an approved copy of the data. The current analytical laboratory for the WRRP is the Weck
Laboratories Inc., located in the City of Industry, California, 91745, www.wecklabs.com. The laboratory
contact is Kim Tu, telephone: (626) 336-2139 and fax: (626) 336-2634, kim@wecklabs.com. As the
contract manager, WRPP is aware of the most current contract laboratory and contact information. If
you have any questions, please contact WRPP directly.
Field activities will be documented through field notes, electronic records and/or photographic records.
Field personnel will be responsible for maintaining field logs and more specific records for individual
tasks being performed. Information recorded in field logs will include, but may not be limited to, the
following:
x Description of field activities;
x Personnel and companies represented at the sample location or source of the discharge;
x Field and weather conditions;
x Calibration records;
x Deviations from accepted work or sampling plans, accompanied by a justification for the
deviation; and
x Description of equipment problems.
Entries to field logs and task-specific data forms will be made in indelible ink and signed and dated by
the personnel making the entry. If changes to entries are necessary, the person making the change will
cross out the item to be changed with a single line and initial and date the change. An explanation of
the change should be recorded, if necessary.
Photographs of field activities, events of conditions will be supplemented with written records of the
subject, date and time of the photographs. All sample location specific information collected
electronically by computerized or automated measurement devices will be kept on file at the City’s
5.C.c
Packet Pg. 335 Attachment: Draft Sewer System Management Plan Update 2023 (5683 : Sanitary Sewer Management Plan)
WATER QUALITY MONITORING PLAN
CSMWRD WATER QUALITY MONITORING PLAN Page 7
Water Division. Copies of results and records will remain within the Water Division’s project files for a
minimum period of three years.
2.1 – Field Data Sheets
A field record will be kept for each day of fieldwork or sampling. A sampling record will be used for each
sample location to record the information collected during water quality sampling.
Water quality sampling forms will record the following information:
x Sample identification;
x Duplicate identification, if applicable;
x Date and time sampled;
x Sample location (i.e. outfall name & GIS coordinates);
x Owner’s name of site of discharge source;
x Extraordinary circumstances (if any);
x Results of instrument calibration/standardization and field measurements (temperature, pH, EC)
and observed relative turbidity;
x Depth from which sample was obtained (if from a diversion structure);
x Number and type of sample container(s); and
x Times and volumes corresponding to water quality measurement.
2.2 – Chain-of-Custody Procedures
The methodology described within this section is in general accordance with the procedures described
in ASTM Standard D4840-88 (1993) (Practice for Sampling Chain-of-Custody Procedures) (ASTM, 1993b).
After samples have been collected and labeled, they will be maintained under chain-of-custody (COC)
procedures. These procedures document the transfer of custody of samples from the field to the
laboratory. Each sample sent to the laboratory for analysis will be recorded on a COC record, which will
include instructions to the laboratory for analytical services.
Information contained on the triplicate COC record will include:
x Project number;
x Signature of sampler(s);
x Date and time sampled;
x Sample identification;
x Number of sample containers;
x Sample matrix (water);
5.C.c
Packet Pg. 336 Attachment: Draft Sewer System Management Plan Update 2023 (5683 : Sanitary Sewer Management Plan)
WATER QUALITY MONITORING PLAN
CSMWRD WATER QUALITY MONITORING PLAN Page 8
x Analyses required;
x Remarks, including preservatives, special conditions, or specific quality control measures;
x Turnaround time and person to receive laboratory report;
x Method of shipment to the laboratory (i.e. hand delivered, courier, etc.;
x Release signature of sampler(s), and signatures of all people assuming custody; and
x Condition of samples when received by the laboratory.
Blank spaces on the COC record will be crossed out between the last sample listed and the signatures at
the bottom of the sheet.
The field sampler will sign the COC record and will record the time and date at the time of transfer to
the laboratory or to an intermediate person. A set of signatures is required for each
relinquished/reserved transfer, including transfer within the City Water Division. The original imprint of
the COC record will accompany the sample containers. A duplicate copy will be placed in the project
file.
If the samples are to be shipped to the laboratory, the original COC record will be sealed inside a plastic
Ziploc bag within the ice chest, and the chest will be sealed with custody tape, which has been signed
and dated by the last person listed on the chain-of-custody. U.S. Department of Transportation (USDOT)
shipping requirements will be followed and the sample shipping receipt will be retained in the project
files as part of the permanent COC document. It is required that the shipping company not sign the COC
forms as a receiver; instead the laboratory will sign as a receiver when the samples are delivered at the
laboratory.
Note: The standard operating procedure is to hand deliver the samples to the lab, or use a lab provided
courier.

CSMWRD WATER QUALITY MONITORING PLAN Page 9
3.0 – Equipment Cleaning
Equipment or sampling apparatus that contacts a sample will be decontaminated prior to use unless it is
pre-cleaned during manufacture and has remained in its sanitary seal or other original packaging (i.e.
disposable equipment). The purpose of decontamination is to minimize the potential for cross
contamination during investigation activities.
Bailers, sampling pumps, and other non-dedicated purging or sampling apparatus will be cleaned before
and after sampling each location. Factory new and sealed disposable bailers may be used for sampling,
but may not be reused. Thermometers, pH electrodes, and EC probes that will be used repeatedly, will
be cleaned before and after each sampling and at any time during sampling if the object comes in
contact with foreign matter.
Cleaning of reusable equipment (water level probe, submersible pump, etc.) that is not dedicated to a
particular sample location will consist of the following:
x Bailers – the inside and outside of bailers will be cleaned in a solution of biodegradable
detergent and potable water, followed by a rinse with deionized (DI) water. The bailers may
also be steam cleaned, followed by a DI water rinse;
x Pumps – downhole, reusable portions of purge pumps will be steam cleaned on the outside or
washed with laboratory-grade detergent followed by a potable water rinse. If the pump does
not have a backflow check valve, the inside of the pump and tubing should also be steam
cleaned. For a purge pump with a backflow check valve, the interior of the pump and tubing
may be cleaned by pumping a laboratory grade detergent and potable water solution through
the system followed by a potable water rinse, or by steam cleaning; and
x Water Quality Meters – meters will be cleaned by rinsing the portion of the probe that was in
contact with the groundwater sample in DI water, and allowing it to air dry.
Sample bottles and bottle caps will be provided by the subcontracted laboratory using standard U.S. EPA
approved protocols. Sample bottles and bottle caps will be protected from contact with solvents, dust,
or other contamination. Sample bottles will not be reused.

THE ADVANTAGES ARE CLEAR•Reduction of plumbing repair bills•Prevention of costly property damage,business interruption and/or expensive,unpleasant cleanup due toclogged sewers and overflows •Protection from potential health hazards caused by theaccumulation of fats,oils,grease and food particles in yoursewer pipes•Protection for marine life and swimmers from health risksand beach closures due to sewage overflows spilling intoour storm drain system.•Protection for our sanitary sewer system and the Hyperion Water Treatment Plant.COMPLIANCE IS MANDATORYAll restaurants,eateries and food preparation facilities musthave a valid Industrial Wastewater Permit.This permit definesdischarge limitations established by the City Ordinance 5.20.40and the U.S.Environmental Protection Agency under theFederal Clean Water Act.Your permit may also require theinstallation of a pretreatment equipment.We encourage business and property owners to take pro-active steps towards preventing fats,oils,and grease fromentering the sewer system by implementing “ Best ManagementPractices”(BMP’s).We regularly monitor wastewater enteringthe sewer and stormdrain systems from your facilities andalert you to any discharges that exceed the limits specified inyour Industrial Wastewater Permit.Our staff will help youidentify the source of the problem,recommend solutions andgive you time to correct the situation.In the event non-compliance continues without resolution,we may be forcedto deny sewer service to your facility.If you have questions about thepermitting process,pretreatmentsystems,or testing,please don’t hesitate to call us at 310-458-8235.For water conservation informa-tion,please call 310-458-8972 ext 1.We are pleased to provide youwith the practical and technicalinformation you need to protectyour business,the public health,and our environment.Use of an in-ground greaseinterceptor prevents grease,oil and fat from reaching Santa Monica Bay.Constant testing of wastewaterdischarges into the sewer andstormdrains helps to ensurethe health of the public and Santa Monica Bay.WE ARE HERE TO ANSWER YOUR QUESTIONSWE ARE HERE TO ANSWER YOUR QUESTIONSWater Pollution Prevention Industrial Waste SectionCity of Santa Monica 1212 5th Street,3rd FloorSanta Monica,CA 90404Tel:310-458-8235CITY OF SANTA MONICA WATER POLLUTION PREVENTIONFOR FOOD ESTABLISHMENTShttp://epwm.santa-monica.org/epwmWater Pollution Prevention Industrial Waste SectionCity of Santa Monica 1212 5th Street,3rd FloorSanta Monica,CA 90404Tel:310-458-8235http://epwm.santa-monica.org/epwmStop the F.O.G.From Rolling In...Make Our Bay A Safe PlaceTo Swim & PlayStop the F.O.G.From Rolling In...Make Our Bay A Safe PlaceTo Swim & Play5.C.cPacket Pg. 348Attachment: Draft Sewer System Management Plan Update 2023 (5683 : Sanitary Sewer Management
A "GRADE A" BAY...WHY NOT?Clean beaches,storm drains,and sewers are just good business.You do everything you can to keep customers comingback.Obviously,sewer overflows and backups are not conducive to repeat business.Often,cooking by-products containing grease are washed intoyour plumbing system through the sinks and floor drains inyour food preparation areas.Over time,the grease clogs yourpipes,sewer lines become blocked,and you have a costly,inconvenient problem to fix,but your problem can becomeeveryone else’s problem,too.Once sewer lines become blocked,wastewater full of fat,oil andgrease are forced up through manhole (utility) covers onto ourstreets and into our storm drain system.The untreated sewageflows through our storm drains to thebeach(see diagram below).Our beaches get poor grades for cleanlinessand sometimes are closed to the public due to significant health risks.The dangerous pathogens found in waste water are not favorable to marine citizens and businesses.Our Water Pollution Prevention Program is designed to protect public health,our environment and your business.THE SOLUTION...BEST MANAGEMENT PRACTICES Prevent fats,oils and grease from entering your pipes and thesewer system. These simple “Best Management Practices”will enable your restaurant to operate efficiently,safely and cost effectively.•Install anappropriatelysized greasetrap or interceptor inyour place ofbusiness.•Maintain,clean and service your grease trap orinterceptor regularly.•Filter screens should not be washed on-site.A filter cleaningservice must be used,unless you have a grease interceptor.•Do not use prohibited substances such as chlorine,acids and solvents with your grease trap or interceptor,as they may cause serious damage to your pretreatment system and the environment.•Be cautious of chemicals and additives that claim to dissolve grease (including soaps and detergents). Often,these substances move the grease down your pipes onlyto clog sewer lines elsewhere.•Collect used grease and oil in a proper container that provides secondary containment and recycle.Do not pourgrease into sink,floor drains,or in dumpsters.•Scrape solids and food scraps from cooking surfaces,plates and utensils into the trash can.Recycle food scrapswhenever possible.The use of garbage disposals is strictly prohibited.•Wash mats and equipment indoors,near kitchen floordrain,or in janitor’s sink.Remember,untreated water inour storm drainsflow into the ocean.•In the event of agrease spill in thealley or parking lot,use dry method forspill cleanup suchas kitty litter. Do not hose down spills.•Sweep up food particles,cigarette butts,dirt,sediment andtrash from outside areas before rinsing or steam cleaningsurfaces.Use equipment that minimizes water useage andrunoff.Do not use toxic bleaches or detergents whichcould run into storm drains.Mop up excess waterand dispose of intoilet,sink,orfloor drains connected to thesanitary sewer.Sewer lines take waste water to Hyperion Waste Water Treatment PlantExcessive grease contributes to blocked pipes cause sewer overflows intostorm drains leading into the Santa Monica Bay.Recycle grease,do not pourdown drain.The storm drains take untreated waste water to the bay.The above diagram shows how an underground grease interceptor prevents fats,oils,and grease from entering the sanitary sewersystem.Clogged drain.5.C.cPacket Pg. 349Attachment: Draft Sewer System Management Plan Update 2023 (5683 : Sanitary Sewer Management
