INTRODUCTION
On May 2, 2006 the California State Water Resources Control Board (SWRCB)
promulgated Statewide General Waste Discharge Requirements (WDRs) for Sanitary
Sewer Systems, Order No. 2006-0003, to regulate sanitary sewer systems greater than
one mile in length. On July 30, 2013 SWRCB Order No. WQO 2013-0058-EXEC, also
known as Attachment A, was promulgated amending the Monitoring and Reporting
Program (MRP) for the Statewide General Waste Discharge Requirements for Sanitary
Sewer Systems. This order became effective on September 9, 2013. Together these
documents constitute the SSS WDR. The WDR Order No. 2006-0003 and WQO 2013-
0058-EXEC have been included in Appendix A.
The SSS WDR prohibits sanitary sewer overflows (SSOs), but if an SSO occurs,
reporting is required using the statewide electronic reporting system. In efforts to
reduce, prevent and mitigate any SSOs, local public wastewater collection system
agencies referred to as “Enrollees,” are required under the SSS WDR to develop,
maintain and implement a Sewer System Management Plan (SSMP). The SSMP should
provide a plan and schedule to properly manage, operate, and maintain all parts of the
sanitary sewer system.
This SSMP has been prepared by Yorba Linda Water District (District) staff in
compliance with the requirements of the SSS WDR. The SSMP addresses the following
elements:
1. Goals
2. Organization
3. Legal Authority
4. Operations and Maintenance Program
5. Design and Performance Provisions
6. Overflow Emergency Response Plan (OERP)
7. Fats, Oils, and Grease (FOG) Control Program
8. System Evaluation and Capacity Assurance Plan
9. Monitoring, Measurement, and Program Modifications
10. SSMP Program Audits
11. Communications Program
The District will update the SSMP at least once every five (5) years, or whenever
significant changes are made. All significant changes to the SSMP and five-year
updates will be re-certified per D.14 of the SSS WDR. The next update will be made if
significant changes are made or no later than five (5) years from the date the District
adopted this report.

1.1 WASTEWATER COLLECTION SYSTEM OVERVIEW
Yorba Linda Water District is a public agency serving residents and businesses of
Yorba Linda, and portions of Placentia, Anaheim, and areas of unincorporated Orange
County. Yorba Linda Water District is a special district, independent of all city and
county governments. The District was formed in 1959 and incorporated under the
California water code.
The District owns and maintains approximately 263 miles of pipeline, approximately
6,157 manholes and one (1) sewer lift station within its service area. The collection
system consists primarily of vitrified clay pipes (VCP) with a small portion of polyvinyl
chloride pipes (PVC), ductile iron pipes (DIP), cast iron pipes (CIP), and asbestos
cement pipes (ACP). Pipe diameters range in size from 4-inch to 24-inch, with the
majority of pipes being 8-inches in diameter. The YLWD Wastewater Collection System
Service Area is shown in Figure 1-1.
Wastewater generated within the system flows by gravity to the Orange County
Sanitation District trunk sewers. These trunk sewers route the flow to the Orange
County Sanitation District water treatment plants in Fountain Valley and Huntington
Beach.

ELEMENT 3- LEGAL AUTHORITY
The intent of this Element is to demonstrate the District has the legal authority needed
to comply with the SSMP requirements.
3.1 REGULATORY REQUIREMENTS
Each enrollee must demonstrate, through sanitary sewer system use ordinances,
service agreements, or other legally binding procedures, that it possesses the
necessary legal authority to:
a) Prevent illicit discharges into its sanitary sewer system;
b) Require that sewers and connections be properly designed and constructed;
c) Ensure access for maintenance, inspection, or repairs for portions of the lateral
owned or maintained by the Public Agency;
d) Limit the discharge of fats, oils, and grease and other debris that may cause
blockages, and
e) Enforce any violation of its sewer ordinances.
3.2 DISTRICT LEGAL AUTHORITY
The District is organized and existing under Division 12 of the County Water District Act,
which is found at Water Code 30000 et seq. (“Act”). Section 31105 of the Water Code
states the District “may adopt ordinances relating to the provision of services and
facilities … and the regulation of those services and facilities.”
In general, the District’s Board of Directors has legal authority to set policies, adopt
resolutions, and ordinances for the District. These policies, resolutions and ordinances
ensure compliance with the legal authority requirements of the WDR.
In addition, to the legal authorities mentioned above, the District also has legal
agreements in place with other agencies. The District currently has service and
maintenance agreements in place with Cities located within the District’s wastewater
collection system service area, such as the City of Anaheim, City of Yorba Linda, and
City of Placentia. The District also has agreements in place with the Orange County
Sanitation District that receives and treats wastewater discharged by the District’s
wastewater collection system service area.
3.3 PREVENT ILLICIT DISCHARGES
The legal authority to prevent illicit discharges into the sanitary sewer system is

ELEMENT 4- OPERATION AND MAINTENANCE PROGRAM
The District recognizes the importance of a properly designed and implemented
Operational and Preventative Maintenance Program and maintaining proper compliance
with various regulatory requirements. Proper wastewater collection system maintenance
plays an important role in keeping our community and our environment healthy. The
intent of this Element is to describe the District’s Operations and Maintenance Program.
4.1 REGULATORY REQUIREMENTS
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.
4.2 MAPPING
The District maintains an up-to-date map of the sanitary sewer system using
Geographic Information System (GIS) technology. The GIS map shows all gravity line
segments, force main segments, manholes, clean-outs, chimneys, fittings, grease
interceptors, lift stations, sewer easements, and valves. The GIS map provides facility
July 13, 2021 Page | 17
information such as ownership, year of installation, pipe diameter, material, slope,
manhole depth, upstream, downstream and rim elevations as well as the status of the
facility and other relevant information.
The GIS map is regularly updated to account for changes in the wastewater collection
system, such as new installations or abandonments. The GIS map is maintained
through the Engineering Department. The GIS map is accessible electronically by all
field staff.
4.3 PREVENTIVE OPERATION AND MAINTENANCE ACTIVITIES
The District maintains a robust Operational and Preventative Maintenance Program.
This program consists of weekly, monthly and quarterly scheduled activities as well as
annual preventative maintenance goals. Service Requests, Work Orders, and
Inspections for various wastewater system infrastructure are all managed through a
Computerized Maintenance Management System (CMMS). Weekly activities include a
physical systems check of the District’s Green Crest sewage lift station and vehicle
maintenance. Monthly scheduled activities include cleaning sewer gravity main
segments that have been identified as Enhanced Maintenance Areas and require
frequent maintenance due to a higher risk of FOG blockage such as siphons. The
quarterly maintenance cycle includes cleaning additional sewer gravity main segments
that have been identified as Enhanced Maintenance Areas, but that do not warrant
being on a monthly schedule. Annually contracted services include trenchless point-
repairs and other structural rehabilitations, vector control in sanitary sewer manholes,
and chemical root treatment applications in root-prone areas.
In 2018, the District transitioned from a scheduled, system-wide cleaning program to a
more comprehensive inspection-based program. Operators are dispatched daily to
perform Closed-Circuit Television (CCTV) inspections of strategically assigned areas
and record their findings. The District utilizes the National Association of Sewer Service
Companies (NASSCO) Pipeline Assessment and Certification Program (PACP)
standard for defect identification and assessment. The current Operational and
Preventative Maintenance Program has a targeted, recurring cycle of four years to
complete visual inspections on all of the District’s pipelines. The District is able to more
efficiently focus its cleaning activities so that it does not clean “clean sewers”. Cleaning
activities, if needed, are logged in CMMS and then addressed as required. Pictures and
videos taken at the time of the inspection provide the sewer combination-truck
Operators with the information they need to efficiently handle a work assignment.
Structural defects and any other anomalies are also noted by the Operators and logged
into CMMS. Many small structural defects are handled by District crews using
trenchless repair technologies. In some cases, excavation may be required to replace a
segment of pipe. The District also utilizes outside contracting to perform other
trenchless point-repairs, full manhole-to-manhole CIPP rehabilitation, and manhole
rehabilitation.
July 13, 2021 Page | 18
The performance of the District’s Operational and Preventative Maintenance Program
can be assessed by tracking the number of preventable SSO’s per year per 100 miles
of sewer gravity main. The CMMS platform can be queried to view the maintenance
history of a particular asset. CCTV can be utilized to determine the cause of the SSO,
providing District staff with the information needed to adjust inspection or cleaning
frequencies, repair structural defects, or address other anomalies.
4.4 TRAINING
A combination of conferences, seminars, classes, bi-weekly tailgate meetings, and on-
the-job training is used to provide training regularly to all Operations and Maintenance
employees. Professional certification from the California Water Environment Association
(CWEA) in the field of Collection System Maintenance is required for certain
Maintenance Worker positions.
Contractors working on District sewer projects are also required to have training and
experience working on sanitary collection systems. Contractors are required to provide
references. These references are checked during the selection process of each project.
4.5 EQUIPMENT AND REPLACEMENT PART INVENTORIES
In efforts to minimize downtime in the event of an unplanned failure, the District
maintains an inventory of equipment and replacement parts. Equipment and
replacement part inventories include but are not limited to:
Two sewer
combination-
trucks
Two CCTV
inspection trucks
Crew/Utility truck

ELEMENT 6- OVERFLOW EMERGENCY RESPONSE PLAN
The intent of this Element is to describe the District’s Sanitary Sewer Overflow
Response Plan (SSORP). A copy of the District’s SSORP can be obtained through the
District’s website at www.ylwd-ca.nextrequest.com.
6.1 REGULATORY REQUIREMENTS
Each Enrollee shall develop and implement an overflow emergency response plan that
identifies measures to protect public health and the environment. At a minimum, this
plan must include the following:
a) Proper notification procedures so that the primary responders and regulatory
agencies are informed of all SSOs in a timely manner;
b) A program to ensure appropriate response to all overflows;
c) 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 MRP. All SSOs shall be reported
in accordance with this MRP, the California Water Code, other State Law, and
other applicable Regional Water Board WDR or NPDES permit requirements.
The SSMP should identify the officials who will receive immediate notification;
d) Procedures to ensure that appropriate staff and contractor personnel are aware
of and follow the Emergency Response Plan and are appropriately trained;
e) Procedures to address emergency operations, such as traffic and crowd control
and other necessary response activities; and
f) 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.
6.2 NOTIFICATION
Prompt notification is crucial for response and mitigation efforts to be completed in a
timely manner. The District’s SSORP outlines the proper internal notification
procedures, including a list of appropriate staff with corresponding telephone numbers.
For ease and efficiency, a specific notification procedure with telephone numbers has
been provided in the event of an SSO during normal business hours and an SSO after
normal business hours including weekends and holidays. If additional personnel are
required, the person in charge of the incident shall contact employees from the
employee roster as deemed necessary. A contact list with specific telephone numbers
has been included as part of the SSORP.
July 13, 2021 Page | 22
In addition to the internal notification, the District will immediately notify health agencies
and other impacted entities.
6.3 RESPONSE
The District’s SSORP includes response activities to adequately address various types
of overflows. The SSORP also includes response activities to protect the public, contain
overflows, and perform final clean up. A detailed flow chart illustrating the District’s
emergency response procedures is included as part of the SSORP.
6.4 REPORTING
The level of notification required to comply with regulatory requirements will depend on
the circumstances surrounding the SSO. The volume, impact and location of the SSO
are all determining factors for proper notification and reporting. The SSORP describes
the reporting method and procedures.
The SSORP also provides District personnel with various forms to document and record
SSO information such as the SSO Calculation Form, to calculate the volume of the spill,
and SSO Report Form, for record keeping. These documents are kept on file at the
District’s main office for five years from the date of the SSO occurrence and are
available for review upon State or Regional Water Quality Control Board Executive
Officer’s request.
The SARWQCB Order No. R8-2002-0014, requires all SSOs to be reported to the
Regional Water Quality Control Board and the Orange County Health Care Agency
(OCHCA). SSOs 1,000 gallons or larger are required to be reported to the State of
California Office of Emergency Services (OES).
In general, the SSO Report Form, is completed and the SSO report is certified by the
LRO online through the SWRCB California Integrated Water Quality System (CIWQS)
database.
6.5 TRAINING
All new employees who may have a role in responding to, reporting and/or mitigating an
SSO event receive a copy of the SSORP upon employment. Training on how to use the
SSORP is also provided upon initial employment. Periodic refresher training is provided
including how to estimate the volume of an SSO and how to determine the SSO start
time. Training measures also include field drills and exercises to assure field crews
practice under actual conditions.

ELEMENT 7- FOG CONTROL PROGRAM
SSOs are sometimes caused by a build-up of Fats, Oils, and Grease (FOG). The
District has implemented a FOG Control Program to prevent SSOs. A copy of the FOG
Control Program can be obtained through the District’s website at www.ylwd-
ca.nextrequest.com. The intent of this element is to describe the District’s FOG Control
Program.
7.1 REGULATORY REQUIREMENTS
Enrollee shall evaluate its service area to determine whether a FOG control program is
needed. If an Enrollee determines that a FOG program is not needed, the Enrollee must
provide justification for why it is not needed. If FOG is found to be a problem, the
Enrollee must prepare and implement a FOG source control program to reduce the
amount of these substances discharged to the sanitary sewer system. This plan shall
include the following as appropriate:
a) An implementation plan and schedule for a public education outreach program
that promotes proper disposal of FOG;
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;
c) The legal authority to prohibit discharges to the system and identify measures to
prevent SSOs and blockages caused by FOG;
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;
e) Authority to inspect grease producing facilities, enforcement authorities, and
whether the Enrollee has sufficient staff to inspect and enforce the FOG
ordinance;
f) An identification of sanitary sewer system sections subject to FOG blockages
and establish a cleaning maintenance schedule for each section; and
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.
7.2 PUBLIC OUTREACH
Public education is important for a successful FOG program. The District provides
public outreach and education through various forms such as the YLWD website
(www.ylwd.com) and social media, which has information regarding the FOG Program,
including proper disposal of grease. Utility bill inserts are also occasionally provided by
direct mail with a simple set of guidelines for sewer lateral maintenance, and various
July 13, 2021 Page | 24
options to dispose of grease rather than pouring down the sinks. Public outreach
extends to the Food Service Establishments (FSEs) by providing printed information
regarding proper disposal and control of grease. The printed information addresses the
importance of containment and disposal of grease, as well as a list of grease control
products available from local hardware stores. FSEs can also view a best practices
video on www.ylwd.com.
Under the District’s FOG Control Program the District’s representative (Representative)
visits new restaurants and provides the FOG Notebook to the restaurant owner or
manager. During the initial visit, the Representative explains the contents of the
Notebook which include Kitchen Best Management Practices (BMP) training, cooking oil
recycling/hauling and gravity grease interceptor (if the restaurant has one) maintenance
and cleaning. Kitchen BMP training includes watching a seven-minute video located on
the District’s website, reading the BMP section of the FOG Notebook and review of the
BMP kitchen signage.
7.3 FOG DISPOSAL
FOG generated within the District’s wastewater collection system service area is
required to be removed by the FSE and disposed of during regular maintenance. The
solidified FOG is vacuumed by locally licensed grease haulers and taken to the Orange
County Sanitation District for disposal. See Table 7-1 for a list of local grease haulers.
Table 7-1: Local Licensed Grease Haulers
7.4 LEGAL AUTHORITY
Element 3 of this document discusses the District’s legal authority to prohibit discharges
of FOG into the sewer system.
Measures to prevent SSOs and blockages caused by FOG have been identified in the
District’s Rules and Regulations for Sewer Service by prohibiting FSEs from discharging
FOG in the sewer system.

Grease interceptor and grease trap design shall conform to the current edition of the
Uniform Plumbing Code and shall be constructed in accordance with the design
approved by the Engineering Department.
The District’s FOG Control Program lists the maintenance requirements, which include
inspection and removals of the full content of the interceptor. The maintenance
frequency is as necessary to ensure the combined FOG and solids accumulation does
not exceed 25 percent of the total liquid depth of the grease interceptor. Until there is
sufficient data to establish this threshold, quarterly maintenance is required. Once the
threshold is established, maintenance is required at a minimum, every 6 months.
BMPs are provided as part of the District’s FOG Control Program. The BMPs include,
how to keep FOG from entering the sewer, how to properly handle and dispose of FOG,
prohibitions and expected practices, employee training requirements and an employee
training log.
The District’s FOG Control Program lists record keeping and reporting requirements.
Logs are provided in the FOG Notebook for accurate recording. The following is a list of
records required;
1. Maintenance inspections and grease level monitoring
2. Grease interceptor hauling and cleaning, with associated manifests
3. Recycling of waste cooking oil, with associated manifests
Records are required to be kept for a minimum of 2 years and the District representative
may request records at any time.
7.6 AUTHORITY TO INSPECT AND ENFORCE
Element 3 of this document discusses the District’s legal authority to inspect and
enforce.
District personnel is responsible for inspection and enforcement of the FOG ordinance.
Currently there is sufficient staffing to inspect and enforce the FOG ordinance.
7.7 CLEANING MAINTENANCE SCHEDULE
Sanitary sewer system sections subject to FOG blockages have been identified through
years of maintenance records and CCTV data. The sewer problem areas have been
compiled into a list titled “Enhanced Maintenance Areas” (EMA). The EMA list identifies
each line, issue(s) and the frequency of cleaning required.
7.8 SOURCE CONTROL MEASURES
The FOG Control Program provides source control measures in efforts to minimize or
prevent FOG from entering the sanitary sewer system. A copy of the FOG Control
Program can be obtained through the District’s website at www.ylwd-

ELEMENT 8- SYSTEM EVALUATION AND CAPACITY
ASSURANCE PLAN
This Element provides a summary of the District’s program to evaluate the capacity of
its system to address current and future capacity requirements.
8.1 REGULATORY REQUIREMENTS
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. 14.
8.2 EVALUATION
The District evaluates the maintenance, repair, and replacement of the wastewater
collection system assets by utilizing the Asset Management Plan, the Wastewater
System Master Plan, and operation and maintenance data.
July 13, 2021 Page | 27
Asset Management Plan
The latest Asset Management Plan (AMP) was prepared in 2018. This report provided
an updated forecast and analysis of the needs for the existing wastewater asset
portfolio. The AMP encompassed the current state/condition of the existing
infrastructure assets, risk profile, and future capital needs to sustain the delivery of
service to customers.
The District’s AMP was developed on a risk-based asset renewal (or reinvestment)
prioritization. Where risk corresponds to each asset’s potential to impact the District’s
service. Risk determinations were based on the results of site visits and visual condition
assessments. The risk and need for replacement for below ground pipeline assets were
determined by a GIS-based model using the Innovyze InfoMaster software. The AMP is
updated periodically to include new assets and improvements to existing assets. The
AMP can be found on the District’s website at www.ylwd.com.
Wastewater System Master Plan
The District maintains a Wastewater System Master Plan and updates the plan
periodically to include significant changes in the District’s wastewater collection system.
The District is currently preparing an update to its 2010 YLWD Sewer Master Plan and
hydraulic model. The update will identify system improvements to address capacity
issues and operational efficiencies, as well as provide a plan for implementation of
recommended improvements.
The 2020 Wastewater System Master Plan (WWSMP) includes an update to the
previous plan and hydraulic model of the system utilizing the District’s Geographic
Information System (GIS) geodatabase and flows described below. The GIS database
incorporates system physical characteristics such as pipe size, material, length, slope,
etc.
The average dry weather flows were allocated and calibrated in the wastewater model
based on historical metered water sale records, land use data, and the results of a flow
monitoring program conducted from October 15 to November 6, 2020. Flow monitoring
data from October 26 and 27 were excluded due to the Blue Ridge fire evacuation
orders. Peak dry weather flows were determined using a peaking equation which was
developed based on an analysis of the average and peak dry weather flows monitored
during the temporary flow monitoring program. The current master plan analysis used a
peak flow equation in terms of GPM to match the current model loading, while the 2010
update had previously used MGD.
The District’s existing wastewater collection system was evaluated using existing water
meter data and return-to-sewer ratios to generate flows. These flows were then
calibrated to the wastewater flow monitoring data and compared to existing pipeline
system capacity using the design criteria discussed above.
July 13, 2021 Page | 28
8.3 DESIGN CRITERIA
The sewage flow generation factors will be established as part of the 2020 WWSMP
and be used to determine unit flow coefficients for various land uses. This criteria will be
used to update the District’s Standard Specifications.
Peak Flows
Pipeline design shall be based on the peak flows as determined from Manning’s formula
and the following:
Q(peak) = 2 x Q (avg)
Design peak flows in pipelines 12-inches in diameter and smaller are to be limited to a
flow depth over pipe diameter ratio (d/D) of 50%. Pipes over 12-inches are to be limited
to a flow depth over pipe diameter ratio (d/D) of 75%.
Pipe Size ≤ 12-inches: d/D ≤ 50%
Pipe Size > 12-inches: d/D ≤75%
8.4 CAPACITY ENHANCEMENT MEASURES
The District develops and updates its Capital Improvement Plan (CIP) utilizing historical
information from its CMMS, CCTV data, and reports such as the AMP and the
WWSMP. Once the capacity enhancement projects have been identified and prioritized,
the District budgets for a 5 year capital improvement plan (CIP).
.
8.5 SCHEDULE
The District has prepared a 5-year CIP, which includes projects and implementation
schedules. From time to time, the CIP may be modified to reflect changing conditions
and priorities. The current CIP has been approved through fiscal year 2025 and is
available on the District’s website.

Appendix B – SSMP Change Log & Audits
Appendix C – SSMP Adoption & Certification
STATE WATER RESOURCES CONTROL BOARD
ORDER NO. 2006-0003-DWQ
STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS
FOR
SANITARY SEWER SYSTEMS
The State Water Resources Control Board, hereinafter referred to as “State
Water Board”, finds that:
1. All federal and state agencies, municipalities, counties, districts, and other public
entities that own or operate sanitary sewer systems greater than one mile in
length that collect and/or convey untreated or partially treated wastewater to a
publicly owned treatment facility in the State of California are required to comply
with the terms of this Order. Such entities are hereinafter referred to as
“Enrollees”.
2. Sanitary sewer overflows (SSOs) are overflows from sanitary sewer systems of
domestic wastewater, as well as industrial and commercial wastewater,
depending on the pattern of land uses in the area served by the sanitary sewer
system. SSOs often contain high levels of suspended solids, pathogenic
organisms, toxic pollutants, nutrients, oxygen-demanding organic compounds, oil
and grease and other pollutants. SSOs may cause a public nuisance,
particularly when raw untreated wastewater is discharged to areas with high
public exposure, such as streets or surface waters used for drinking, fishing, or
body contact recreation. SSOs may pollute surface or ground waters, threaten
public health, adversely affect aquatic life, and impair the recreational use and
aesthetic enjoyment of surface waters.
3. Sanitary sewer systems experience periodic failures resulting in discharges that
may affect waters of the state. There are many factors (including factors related
to geology, design, construction methods and materials, age of the system,
population growth, and system operation and maintenance), which affect the
likelihood of an SSO. A proactive approach that requires Enrollees to ensure a
system-wide operation, maintenance, and management plan is in place will
reduce the number and frequency of SSOs within the state. This approach will in
turn decrease the risk to human health and the environment caused by SSOs.
4. Major causes of SSOs include: grease blockages, root blockages, sewer line
flood damage, manhole structure failures, vandalism, pump station mechanical
failures, power outages, excessive storm or ground water inflow/infiltration,
debris blockages, sanitary sewer system age and construction material failures,
lack of proper operation and maintenance, insufficient capacity and contractor-
caused damages. Many SSOs are preventable with adequate and appropriate
facilities, source control measures and operation and maintenance of the sanitary
sewer system.
State Water Resources Control Board Order No. 2006-0003-DWQ Page 2 of 20
Statewide General WDR For Wastewater Collection Agencies 5/2/06
SEWER SYSTEM MANAGEMENT PLANS
5. To facilitate proper funding and management of sanitary sewer systems, each
Enrollee must develop and implement a system-specific Sewer System
Management Plan (SSMP). To be effective, SSMPs must include provisions to
provide proper and efficient management, operation, and maintenance of
sanitary sewer systems, while taking into consideration risk management and
cost benefit analysis. Additionally, an SSMP must contain a spill response plan
that establishes standard procedures for immediate response to an SSO in a
manner designed to minimize water quality impacts and potential nuisance
conditions.
6. Many local public agencies in California have already developed SSMPs and
implemented measures to reduce SSOs. These entities can build upon their
existing efforts to establish a comprehensive SSMP consistent with this Order.
Others, however, still require technical assistance and, in some cases, funding to
improve sanitary sewer system operation and maintenance in order to reduce
SSOs.
7. SSMP certification by technically qualified and experienced persons can provide
a useful and cost-effective means for ensuring that SSMPs are developed and
implemented appropriately.
8. It is the State Water Board’s intent to gather additional information on the causes
and sources of SSOs to augment existing information and to determine the full
extent of SSOs and consequent public health and/or environmental impacts
occurring in the State.
9. Both uniform SSO reporting and a centralized statewide electronic database are
needed to collect information to allow the State Water Board and Regional Water
Quality Control Boards (Regional Water Boards) to effectively analyze the extent
of SSOs statewide and their potential impacts on beneficial uses and public
health. The monitoring and reporting program required by this Order and the
attached Monitoring and Reporting Program No. 2006-0003-DWQ, are necessary
to assure compliance with these waste discharge requirements (WDRs).
10.Information regarding SSOs must be provided to Regional Water Boards and
other regulatory agencies in a timely manner and be made available to the public
in a complete, concise, and timely fashion.
11.Some Regional Water Boards have issued WDRs or WDRs that serve as
National Pollution Discharge Elimination System (NPDES) permits to sanitary
sewer system owners/operators within their jurisdictions. This Order establishes
minimum requirements to prevent SSOs. Although it is the State Water Board’s
intent that this Order be the primary regulatory mechanism for sanitary sewer
systems statewide, Regional Water Boards may issue more stringent or more
State Water Resources Control Board Order No. 2006-0003-DWQ Page 3 of 20
Statewide General WDR For Wastewater Collection Agencies 5/2/06
prescriptive WDRs for sanitary sewer systems. Upon issuance or reissuance of
a Regional Water Board’s WDRs for a system subject to this Order, the Regional
Water Board shall coordinate its requirements with stated requirements within
this Order, to identify requirements that are more stringent, to remove
requirements that are less stringent than this Order, and to provide consistency
in reporting.
REGULATORY CONSIDERATIONS
12. California Water Code section 13263 provides that the State Water Board may
prescribe general WDRs for a category of discharges if the State Water Board
finds or determines that:
• The discharges are produced by the same or similar operations;
• The discharges involve the same or similar types of waste;
• The discharges require the same or similar treatment standards; and
• The discharges are more appropriately regulated under general discharge
requirements than individual discharge requirements.
This Order establishes requirements for a class of operations, facilities, and
discharges that are similar throughout the state.
13.The issuance of general WDRs to the Enrollees will:
a) Reduce the administrative burden of issuing individual WDRs to each
Enrollee;
b) Provide for a unified statewide approach for the reporting and database
tracking of SSOs;
c) Establish consistent and uniform requirements for SSMP development
and implementation;
d) Provide statewide consistency in reporting; and
e) Facilitate consistent enforcement for violations.
14.The beneficial uses of surface waters that can be impaired by SSOs include, but
are not limited to, aquatic life, drinking water supply, body contact and non-
contact recreation, and aesthetics. The beneficial uses of ground water that can
be impaired include, but are not limited to, drinking water and agricultural supply.
Surface and ground waters throughout the state support these uses to varying
degrees.
15.The implementation of requirements set forth in this Order will ensure the
reasonable protection of past, present, and probable future beneficial uses of
water and the prevention of nuisance. The requirements implement the water
quality control plans (Basin Plans) for each region and take into account the
environmental characteristics of hydrographic units within the state. Additionally,
the State Water Board has considered water quality conditions that could
reasonably be achieved through the coordinated control of all factors that affect
State Water Resources Control Board Order No. 2006-0003-DWQ Page 4 of 20
Statewide General WDR For Wastewater Collection Agencies 5/2/06
water quality in the area, costs associated with compliance with these
requirements, the need for developing housing within California, and the need to
develop and use recycled water.
16.The Federal Clean Water Act largely prohibits any discharge of pollutants from a
point source to waters of the United States except as authorized under an
NPDES permit. In general, any point source discharge of sewage effluent to
waters of the United States must comply with technology-based, secondary
treatment standards, at a minimum, and any more stringent requirements
necessary to meet applicable water quality standards and other requirements.
Hence, the unpermitted discharge of wastewater from a sanitary sewer system to
waters of the United States is illegal under the Clean Water Act. In addition,
many Basin Plans adopted by the Regional Water Boards contain discharge
prohibitions that apply to the discharge of untreated or partially treated
wastewater. Finally, the California Water Code generally prohibits the discharge
of waste to land prior to the filing of any required report of waste discharge and
the subsequent issuance of either WDRs or a waiver of WDRs.
17.California Water Code section 13263 requires a water board to, after any
necessary hearing, prescribe requirements as to the nature of any proposed
discharge, existing discharge, or material change in an existing discharge. The
requirements shall, among other things, take into consideration the need to
prevent nuisance.
18.California Water Code section 13050, subdivision (m), defines nuisance as
anything which meets all of the following requirements:
a. Is injurious to health, or is indecent or offensive to the senses, or an
obstruction to the free use of property, so as to interfere with the
comfortable enjoyment of life or property.
b. Affects at the same time an entire community or neighborhood, or any
considerable number of persons, although the extent of the annoyance or
damage inflicted upon individuals may be unequal.
c. Occurs during, or as a result of, the treatment or disposal of wastes.
19.This Order is consistent with State Water Board Resolution No. 68-16 (Statement
of Policy with Respect to Maintaining High Quality of Waters in California) in that
the Order imposes conditions to prevent impacts to water quality, does not allow
the degradation of water quality, will not unreasonably affect beneficial uses of
water, and will not result in water quality less than prescribed in State Water
Board or Regional Water Board plans and policies.
20.The action to adopt this General Order is exempt from the California
Environmental Quality Act (Public Resources Code §21000 et seq.) because it is
an action taken by a regulatory agency to assure the protection of the
environment and the regulatory process involves procedures for protection of the
environment. (Cal. Code Regs., tit. 14, §15308). In addition, the action to adopt
State Water Resources Control Board Order No. 2006-0003-DWQ Page 5 of 20
Statewide General WDR For Wastewater Collection Agencies 5/2/06
this Order is exempt from CEQA pursuant to Cal.Code Regs., title 14, §15301 to
the extent that it applies to existing sanitary sewer collection systems that
constitute “existing facilities” as that term is used in Section 15301, and §15302,
to the extent that it results in the repair or replacement of existing systems
involving negligible or no expansion of capacity.
21.The Fact Sheet, which is incorporated by reference in the Order, contains
supplemental information that was also considered in establishing these
requirements.
22.The State Water Board has notified all affected public agencies and all known
interested persons of the intent to prescribe general WDRs that require Enrollees
to develop SSMPs and to report all SSOs.
23.The State Water Board conducted a public hearing on February 8, 2006, to
receive oral and written comments on the draft order. The State Water Board
received and considered, at its May 2, 2006, meeting, additional public
comments on substantial changes made to the proposed general WDRs
following the February 8, 2006, public hearing. The State Water Board has
considered all comments pertaining to the proposed general WDRs.
IT IS HEREBY ORDERED, that pursuant to California Water Code section 13263, the
Enrollees, their agents, successors, and assigns, in order to meet the provisions
contained in Division 7 of the California Water Code and regulations adopted
hereunder, shall comply with the following:
A. DEFINITIONS
1. Sanitary sewer overflow (SSO) - Any overflow, spill, release, discharge or
diversion of untreated or partially treated wastewater from a sanitary sewer
system. SSOs include:
(i) Overflows or releases of untreated or partially treated wastewater that
reach waters of the United States;
(ii) Overflows or releases of untreated or partially treated wastewater that do
not reach waters of the United States; and
(iii) Wastewater backups into buildings and on private property that are
caused by blockages or flow conditions within the publicly owned portion
of a sanitary sewer system.
2. Sanitary sewer system – Any system of pipes, pump stations, sewer lines, or
other conveyances, upstream of a wastewater treatment plant headworks used
to collect and convey wastewater to the publicly owned treatment facility.
Temporary storage and conveyance facilities (such as vaults, temporary piping,
construction trenches, wet wells, impoundments, tanks, etc.) are considered to
be part of the sanitary sewer system, and discharges into these temporary
storage facilities are not considered to be SSOs.

5. Untreated or partially treated wastewater – Any volume of waste discharged
from the sanitary sewer system upstream of a wastewater treatment plant
headworks.
6. Satellite collection system – The portion, if any, of a sanitary sewer system
owned or operated by a different public agency than the agency that owns and
operates the wastewater treatment facility to which the sanitary sewer system is
tributary.
7. Nuisance - California Water Code section 13050, subdivision (m), defines
nuisance as anything which meets all of the following requirements:
a. Is injurious to health, or is indecent or offensive to the senses, or an
obstruction to the free use of property, so as to interfere with the
comfortable enjoyment of life or property.
b. Affects at the same time an entire community or neighborhood, or any
considerable number of persons, although the extent of the annoyance or
damage inflicted upon individuals may be unequal.
c. Occurs during, or as a result of, the treatment or disposal of wastes.
B. APPLICATION REQUIREMENTS
1. Deadlines for Application – All public agencies that currently own or operate
sanitary sewer systems within the State of California must apply for coverage
under the general WDRs within six (6) months of the date of adoption of the
general WDRs. Additionally, public agencies that acquire or assume
responsibility for operating sanitary sewer systems after the date of adoption of
this Order must apply for coverage under the general WDRs at least three (3)
months prior to operation of those facilities.
2. Applications under the general WDRs – In order to apply for coverage pursuant
to the general WDRs, a legally authorized representative for each agency must
submit a complete application package. Within sixty (60) days of adoption of the
general WDRs, State Water Board staff will send specific instructions on how to
State Water Resources Control Board Order No. 2006-0003-DWQ Page 7 of 20
Statewide General WDR For Wastewater Collection Agencies 5/2/06
apply for coverage under the general WDRs to all known public agencies that
own sanitary sewer systems. Agencies that do not receive notice may obtain
applications and instructions online on the Water Board’s website.
3. Coverage under the general WDRs – Permit coverage will be in effect once a
complete application package has been submitted and approved by the State
Water Board’s Division of Water Quality.
C. PROHIBITIONS
1. Any SSO that results in a discharge of untreated or partially treated wastewater
to waters of the United States is prohibited.
2. Any SSO that results in a discharge of untreated or partially treated wastewater
that creates a nuisance as defined in California Water Code Section 13050(m) is
prohibited.
D. PROVISIONS
1. The Enrollee must comply with all conditions of this Order. Any noncompliance
with this Order constitutes a violation of the California Water Code and is
grounds for enforcement action.
2. It is the intent of the State Water Board that sanitary sewer systems be regulated
in a manner consistent with the general WDRs. Nothing in the general WDRs
shall be:
(i) Interpreted or applied in a manner inconsistent with the Federal Clean
Water Act, or supersede a more specific or more stringent state or
federal requirement in an existing permit, regulation, or
administrative/judicial order or Consent Decree;
(ii) Interpreted or applied to authorize an SSO that is illegal under either the
Clean Water Act, an applicable Basin Plan prohibition or water quality
standard, or the California Water Code;
(iii) Interpreted or applied to prohibit a Regional Water Board from issuing an
individual NPDES permit or WDR, superseding this general WDR, for a
sanitary sewer system, authorized under the Clean Water Act or
California Water Code; or
(iv) Interpreted or applied to supersede any more specific or more stringent
WDRs or enforcement order issued by a Regional Water Board.
3. The Enrollee shall take all feasible steps to eliminate SSOs. In the event that an
SSO does occur, the Enrollee shall take all feasible steps to contain and mitigate
the impacts of an SSO.
4. In the event of an SSO, the Enrollee shall take all feasible steps to prevent
untreated or partially treated wastewater from discharging from storm drains into
State Water Resources Control Board Order No. 2006-0003-DWQ Page 8 of 20
Statewide General WDR For Wastewater Collection Agencies 5/2/06
flood control channels or waters of the United States by blocking the storm
drainage system and by removing the wastewater from the storm drains.
5. All SSOs must be reported in accordance with Section G of the general WDRs.
6. In any enforcement action, the State and/or Regional Water Boards will consider
the appropriate factors under the duly adopted State Water Board Enforcement
Policy. And, consistent with the Enforcement Policy, the State and/or Regional
Water Boards must consider the Enrollee’s efforts to contain, control, and
mitigate SSOs when considering the California Water Code Section 13327
factors. In assessing these factors, the State and/or Regional Water Boards will
also consider whether:
(i) The Enrollee has complied with the requirements of this Order, including
requirements for reporting and developing and implementing a SSMP;
(ii) The Enrollee can identify the cause or likely cause of the discharge event;
(iii) There were no feasible alternatives to the discharge, such as temporary
storage or retention of untreated wastewater, reduction of inflow and
infiltration, use of adequate backup equipment, collecting and hauling of
untreated wastewater to a treatment facility, or an increase in the
capacity of the system as necessary to contain the design storm event
identified in the SSMP. It is inappropriate to consider the lack of feasible
alternatives, if the Enrollee does not implement a periodic or continuing
process to identify and correct problems.
(iv)The discharge was exceptional, unintentional, temporary, and caused by
factors beyond the reasonable control of the Enrollee;
(v) The discharge could have been prevented by the exercise of reasonable
control described in a certified SSMP for:
• Proper management, operation and maintenance;
• Adequate treatment facilities, sanitary sewer system facilities,
and/or components with an appropriate design capacity, to
reasonably prevent SSOs (e.g., adequately enlarging treatment or
collection facilities to accommodate growth, infiltration and inflow
(I/I), etc.);
• Preventive maintenance (including cleaning and fats, oils, and
grease (FOG) control);
• Installation of adequate backup equipment; and
• Inflow and infiltration prevention and control to the extent
practicable.
(vi)The sanitary sewer system design capacity is appropriate to reasonably
prevent SSOs.
State Water Resources Control Board Order No. 2006-0003-DWQ Page 9 of 20
Statewide General WDR For Wastewater Collection Agencies 5/2/06
(vii) The Enrollee took all reasonable steps to stop and mitigate the impact of
the discharge as soon as possible.
7. When a sanitary sewer overflow occurs, the Enrollee shall take all feasible steps
and necessary remedial actions to 1) control or limit the volume of untreated or
partially treated wastewater discharged, 2) terminate the discharge, and 3)
recover as much of the wastewater discharged as possible for proper disposal,
including any wash down water.
The Enrollee shall implement all remedial actions to the extent they may be
applicable to the discharge and not inconsistent with an emergency response
plan, including the following:
(i) Interception and rerouting of untreated or partially treated wastewater
flows around the wastewater line failure;
(ii) Vacuum truck recovery of sanitary sewer overflows and wash down
water;
(iii) Cleanup of debris at the overflow site;
(iv) System modifications to prevent another SSO at the same location;
(v) Adequate sampling to determine the nature and impact of the release;
and
(vi) Adequate public notification to protect the public from exposure to the
SSO.
8. The Enrollee shall properly, manage, operate, and maintain all parts of the
sanitary sewer system owned or operated by the Enrollee, and shall ensure that
the system operators (including employees, contractors, or other agents) are
adequately trained and possess adequate knowledge, skills, and abilities.
9. The Enrollee shall allocate adequate resources for the operation, maintenance,
and repair of its sanitary sewer system, by establishing a proper rate structure,
accounting mechanisms, and auditing procedures to ensure an adequate
measure of revenues and expenditures. These procedures must be in
compliance with applicable laws and regulations and comply with generally
acceptable accounting practices.
10.The Enrollee shall provide adequate capacity to convey base flows and peak
flows, including flows related to wet weather events. Capacity shall meet or
exceed the design criteria as defined in the Enrollee’s System Evaluation and
Capacity Assurance Plan for all parts of the sanitary sewer system owned or
operated by the Enrollee.
11.The Enrollee shall develop and implement a written Sewer System Management
Plan (SSMP) and make it available to the State and/or Regional Water Board
upon request. A copy of this document must be publicly available at the
Enrollee’s office and/or available on the Internet. This SSMP must be approved
by the Enrollee’s governing board at a public meeting.
State Water Resources Control Board Order No. 2006-0003-DWQ Page 10 of 20
Statewide General WDR For Wastewater Collection Agencies 5/2/06
12.In accordance with the California Business and Professions Code sections 6735,
7835, and 7835.1, all engineering and geologic evaluations and judgments shall
be performed by or under the direction of registered professionals competent and
proficient in the fields pertinent to the required activities. Specific elements of the
SSMP that require professional evaluation and judgments shall be prepared by
or under the direction of appropriately qualified professionals, and shall bear the
professional(s)’ signature and stamp.
13.The mandatory elements of the SSMP are specified below. However, if the
Enrollee believes that any element of this section is not appropriate or applicable
to the Enrollee’s sanitary sewer system, the SSMP program does not need to
address that element. The Enrollee must justify why that element is not
applicable. The SSMP must be approved by the deadlines listed in the SSMP
Time Schedule below.
Sewer System Management Plan (SSMP)
(i) Goal: The goal of the SSMP is to provide a plan and schedule to properly
manage, operate, and maintain all parts of the sanitary sewer system.
This will help reduce and prevent SSOs, as well as mitigate any SSOs
that do occur.
(ii) Organization: The SSMP must identify:
(a) The name of the responsible or authorized representative as
described in Section J of this Order.
(b) The names and telephone numbers for management,
administrative, and maintenance positions responsible for
implementing specific measures in the SSMP program. The
SSMP must identify lines of authority through an organization chart
or similar document with a narrative explanation; and
(c) The chain of communication for reporting SSOs, from receipt of a
complaint or other information, including the person responsible for
reporting SSOs to the State and Regional Water Board and other
agencies if applicable (such as County Health Officer, County
Environmental Health Agency, Regional Water Board, and/or State
Office of Emergency Services (OES)).
(iii) Legal Authority: Each Enrollee must demonstrate, through sanitary
sewer system use ordinances, service agreements, or other legally
binding procedures, that it possesses the necessary legal authority to:
(a) Prevent illicit discharges into its sanitary sewer system
(examples may include I/I, stormwater, chemical dumping,
unauthorized debris and cut roots, etc.);
State Water Resources Control Board Order No. 2006-0003-DWQ Page 11 of 20
Statewide General WDR For Wastewater Collection Agencies 5/2/06
(b) Require that sewers and connections be properly designed
and constructed;
(c) Ensure access for maintenance, inspection, or repairs for
portions of the lateral owned or maintained by the Public
Agency;
(d) Limit the discharge of fats, oils, and grease and other debris
that may cause blockages, and
(e) Enforce any violation of its sewer ordinances.
(iv) Operation and Maintenance Program. 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 stormwater
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 a rehabilitation and replacement plan to identify and
prioritize system deficiencies and implement short-term and long-
term rehabilitation actions to address each deficiency. The
program should include regular visual and TV inspections of
manholes and sewer pipes, and a system for ranking the
condition of sewer pipes and scheduling rehabilitation.
Rehabilitation and replacement should focus on sewer pipes that
are at risk of collapse or prone to more frequent blockages due to
pipe defects. Finally, the rehabilitation and replacement plan
should include a capital improvement plan that addresses proper
management and protection of the infrastructure assets. The plan
shall include a time schedule for implementing the short- and
long-term plans plus a schedule for developing the funds needed
for the capital improvement plan;
(d) Provide training on a regular basis for staff in sanitary sewer
system operations and maintenance, and require contractors to
be appropriately trained; and
State Water Resources Control Board Order No. 2006-0003-DWQ Page 12 of 20

(e) Provide equipment and replacement part inventories, including
identification of critical replacement parts.
(v) Design and Performance Provisions:
(a) Design and construction standards and specifications for the
installation of new sanitary sewer systems, pump stations and other
appurtenances; and for the rehabilitation and repair of existing
sanitary sewer systems; and
(b) Procedures and standards for inspecting and testing the installation
of new sewers, pumps, and other appurtenances and for
rehabilitation and repair projects.
(vi) Overflow Emergency Response Plan -Each Enrollee shall develop and
implement an overflow emergency response plan that identifies
measures to protect public health and the environment. At a minimum,
this plan must include the following:
(a) Proper notification procedures so that the primary responders and
regulatory agencies are informed of all SSOs in a timely manner;
(b) A program to ensure an appropriate response to all overflows;
(c) 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 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;
(d) Procedures to ensure that appropriate staff and contractor
personnel are aware of and follow the Emergency Response Plan
and are appropriately trained;
(e) Procedures to address emergency operations, such as traffic and
crowd control and other necessary response activities; and
(f) 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.
State Water Resources Control Board Order No. 2006-0003-DWQ Page 13 of 20
Statewide General WDR For Wastewater Collection Agencies 5/2/06
(vii) FOG Control Program: Each Enrollee shall evaluate its service area to
determine whether a FOG control program is needed. If an Enrollee
determines that a FOG program is not needed, the Enrollee must provide
justification for why it is not needed. If FOG is found to be a problem, the
Enrollee must prepare and implement a FOG source control program to
reduce the amount of these substances discharged to the sanitary sewer
system. This plan shall include the following as appropriate:
(a) An implementation plan and schedule for a public education
outreach program that promotes proper disposal of FOG;
(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;
(c) The legal authority to prohibit discharges to the system and
identify measures to prevent SSOs and blockages caused by
FOG;
(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;
(e) Authority to inspect grease producing facilities, enforcement
authorities, and whether the Enrollee has sufficient staff to inspect
and enforce the FOG ordinance;
(f) An identification of sanitary sewer system sections subject to
FOG blockages and establishment of a cleaning maintenance
schedule for each section; and
(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.
(viii) System Evaluation and Capacity Assurance Plan: 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
State Water Resources Control Board Order No. 2006-0003-DWQ Page 14 of 20
Statewide General WDR For Wastewater Collection Agencies 5/2/06
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 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. 14.
(ix) Monitoring, Measurement, and Program Modifications: 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 preventative maintenance
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.
(x) SSMP Program Audits - 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
State Water Resources Control Board Order No. 2006-0003-DWQ Page 15 of 20
Statewide General WDR For Wastewater Collection Agencies 5/2/06
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.
(xi) Communication Program – 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.
14.Both the SSMP and the Enrollee’s program to implement the SSMP must be
certified by the Enrollee to be in compliance with the requirements set forth
above and must be presented to the Enrollee’s governing board for approval at a
public meeting. The Enrollee shall certify that the SSMP, and subparts thereof,
are in compliance with the general WDRs within the time frames identified in the
time schedule provided in subsection D.15, below.
In order to complete this certification, the Enrollee’s authorized representative

STATE OF CALIFORNIA
WATER RESOURCES CONTROL BOARD
ORDER NO. WQ 2013-0058-EXEC
AMENDING MONITORING AND REPORTING PROGRAM
FOR
STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS FOR
SANITARY SEWER SYSTEMS
The State of California, Water Resources Control Board (hereafter State Water Board) finds:
1.The State Water Board is authorized to prescribe statewide general Waste Discharge
Requirements (WDRs) for categories of discharges that involve the same or similar
operations and the same or similar types of waste pursuant to Water Code section 13263(i).
2.Water Code section 13193 et seq. requires the Regional Water Quality Control Boards
(Regional Water Boards) and the State Water Board (collectively, the Water Boards) to
gather Sanitary Sewer Overflow (SSO) information and make this information available to
the public, including but not limited to, SSO cause, estimated volume, location, date, time,
duration, whether or not the SSO reached or may have reached waters of the state,
response and corrective action taken, and an enrollee's contact information for each SSO
event. An enrollee is defined as the public entity having legal authority over the operation
and maintenance of, or capital improvements to, a sanitary sewer system greater than one
mile in length.
3.Water Code section 13271, et seq. requires notification to the California Office of
Emergency Services (Cal OES), formerly the California Emergency Management Agency,
for certain unauthorized discharges, including SSOs.
4.On May 2, 2006, the State Water Board adopted Order 2006-0003-DWQ, "Statewide Waste
Discharge Requirements for Sanitary Sewer Systems"1 (hereafter SSS WDRs) to comply
with Water Code section 13193 and to establish the framework for the statewide SSO
Reduction Program.
5.Subsection G.2 of the SSS WDRs and the Monitoring and Reporting Program (MRP)
provide that the Executive Director may modify the terms of the MRP at any time.
6.On February 20, 2008, the State Water Board Executive Director adopted a revised MRP for
the SSS WDRs to rectify early notification deficiencies and ensure that first responders are
notified in a timely manner of SSOs discharged into waters of the state.
7.When notified of an SSO that reaches a drainage channel or surface water of the state, Cal
OES, pursuant to Water Code section 13271(a)(3), forwards the SSO notification
information2 to local government agencies and first responders including local public health
officials and the applicable Regional Water Board. Receipt of notifications for a single SSO
event from both the SSO reporter and Cal OES is duplicative. To address this, the SSO
notification requirements added by the February 20, 2008 MRP revision are being removed
in this MRP revision.

Statewide Waste Discharge Requirements for Sanitary Sewer Systems Page 2 of 2
8.In the February 28, 2008 Memorandum of Agreement between the State Water Board and
the California Water and Environment Association (CWEA), the State Water Board
committed to re- designing the CIWQS3 Online SSO Database to allow "event" based SSO
reporting versus the original "location" based reporting. Revisions to this MRP and
accompanying changes to the CIWQS Online SSO Database will implement this change by
allowing for multiple SSO appearance points to be associated with each SSO event caused
by a single asset failure.
9.Based on stakeholder input and Water Board staff experience implementing the SSO
Reduction Program, SSO categories have been revised in this MRP. In the prior version of
the MRP, SSOs have been categorized as Category 1 or Category 2. This MRP implements
changes to SSO categories by adding a Category 3 SSO type. This change will improve
data management to further assist Water Board staff with evaluation of high threat and low
threat SSOs by placing them in unique categories (i.e., Category 1 and Category 3,
respectively). This change will also assist enrollees in identifying SSOs that require Cal OES
notification.
10.Based on over six years of implementation of the SSS WDRs, the State Water Board
concludes that the February 20, 2008 MRP must be updated to better advance the SSO
Reduction Program4 objectives, assess compliance, and enforce the requirements of the
SSS WDRs.
IT IS HEREBY ORDERED THAT:
Pursuant to the authority delegated by Water Code section 13267(f), Resolution 2002-0104,
and Order 2006-0003-DWQ, the MRP for the SSS WDRs (Order 2006-0003-DWQ) is
hereby amended as shown in Attachment A and shall be effective on September 9, 2013.

STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS FOR
SANITARY SEWER SYSTEMS
This Monitoring and Reporting Program (MRP) establishes monitoring, record keeping, reporting and
public notification requirements for Order 2006-0003-DWQ, “Statewide General Waste Discharge
Requirements for Sanitary Sewer Systems” (SSS WDRs). This MRP shall be effective from
September 9, 2013 until it is rescinded. The Executive Director may make revisions to this MRP at
any time. These revisions may include a reduction or increase in the monitoring and reporting
requirements. All site specific records and data developed pursuant to the SSS WDRs and this MRP
shall be complete, accurate, and justified by evidence maintained by the enrollee. Failure to comply
with this MRP may subject an enrollee to civil liabilities of up to $5,000 a day per violation pursuant to
Water Code section 13350; up to $1,000 a day per violation pursuant to Water Code section 13268;
or referral to the Attorney General for judicial civil enforcement. The State Water Resources Control
Board (State Water Board) reserves the right to take any further enforcement action authorized by
law.

B. NOTIFICATION REQUIREMENTS
Although Regional Water Quality Control Boards (Regional Water Boards) and the State
Water Board (collectively, the Water Boards) staff do not have duties as first responders, this
MRP is an appropriate mechanism to ensure that the agencies that have first responder duties
are notified in a timely manner in order to protect public health and beneficial uses.
1. For any Category 1 SSO greater than or equal to 1,000 gallons that results in a discharge to a
surface water or spilled in a location where it probably will be discharged to surface water,
either directly or by way of a drainage channel or MS4, the enrollee shall, as soon as possible,
but not later than two (2) hours after (A) the enrollee has knowledge of the discharge, (B)
notification is possible, and (C) notification can be provided without substantially impeding
cleanup or other emergency measures, notify the Cal OES and obtain a notification control
number.
2. To satisfy notification requirements for each applicable SSO, the enrollee shall provide the
information requested by Cal OES before receiving a control number. Spill information
requested by Cal OES may include:
i. Name of person notifying Cal OES and direct return phone number.
ii. Estimated SSO volume discharged (gallons).
iii. If ongoing, estimated SSO discharge rate (gallons per minute).
iv. SSO Incident Description:
a. Brief narrative.
b. On-scene point of contact for additional information (name and cell phone number).
c. Date and time enrollee became aware of the SSO.
d. Name of sanitary sewer system agency causing the SSO.
e. SSO cause (if known).
v. Indication of whether the SSO has been contained.
vi. Indication of whether surface water is impacted.
vii. Name of surface water impacted by the SSO, if applicable.
viii. Indication of whether a drinking water supply is or may be impacted by the SSO.
ix. Any other known SSO impacts.
x. SSO incident location (address, city, state, and zip code).
3. Following the initial notification to Cal OES and until such time that an enrollee certifies the
SSO report in the CIWQS Online SSO Database, the enrollee shall provide updates to Cal
OES regarding substantial changes to the estimated volume of untreated or partially treated
sewage discharged and any substantial change(s) to known impact(s).
Monitoring and Reporting Program Order No. WQ 2013-0058-EXEC
Statewide Waste Discharge Requirements for Sanitary Sewer Systems Page 5 of 12
4. PLSDs: The enrollee is strongly encouraged to notify Cal OES of discharges greater than or
equal to 1,000 gallons of untreated or partially treated wastewater that result or may result in a
discharge to surface water resulting from failures or flow conditions within a privately owned
sewer lateral or from other private sewer asset(s) if the enrollee becomes aware of the PLSD.
C. REPORTING REQUIREMENTS
1. CIWQS Online SSO Database Account: All enrollees shall obtain a CIWQS Online SSO
Database account and receive a “Username” and “Password” by registering through CIWQS.
These accounts allow controlled and secure entry into the CIWQS Online SSO Database.
2. SSO Mandatory Reporting Information: For reporting purposes, if one SSO event results in
multiple appearance points in a sewer system asset, the enrollee shall complete one SSO
report in the CIWQS Online SSO Database which includes the GPS coordinates for the
location of the SSO appearance point closest to the failure point, blockage or location of the
flow condition that caused the SSO, and provide descriptions of the locations of all other
discharge points associated with the SSO event.
3. SSO Categories
i. Category 1 – Discharges of untreated or partially treated wastewater of any volume
resulting from an enrollee’s sanitary sewer system failure or flow condition that:
a. Reach surface water and/or reach a drainage channel tributary to a surface water; or
b. Reach a MS4 and are not fully captured and returned to the sanitary sewer
system or not otherwise captured and disposed of properly. Any volume of
wastewater not recovered from the MS4 is considered to have reached
surface water unless the storm drain system discharges to a dedicated storm
water or groundwater infiltration basin (e.g., infiltration pit, percolation pond).

SEWER SYSTEM MANAGEMENT PLAN
SELF ASSESSMENT
January/February 2017
1) Goal.
The goal of the SSMP is to provide a plan and schedule to properly
manage, operate, and maintain all parts of the sanitary sewer system.
This will help reduce and prevent SSOs, as well as mitigate any SSOs that
do occur.
Since the last audit in 2015 we have had 4 spills. Two of these were caused
by vandalism, where we have no control, and the other two were category
3. Total volume of the two category 3 spills was around 160 gallons, well
within the bounds of acceptability.
We meet our system goals each year, cleaning all of the system and
televising one fifth of the system.
At present we are planning to update the camera and maybe the camera
vehicle. Final decisions on this will be made around the end of the year.
2) ORGANIZATION
a) The name of the responsible or authorized representative as
described in Section J of this Order.
Nothing has changed here, personnel names may have changed but
job title responsibilities remain the same.
b) The names and telephone numbers for management, administrative,
and maintenance positions responsible for implementing specific
measures in the SSMP program. The SSMP must identify lines of
authority through the organization chart or similar document with a
narrative explanation.
Any changes in personnel information are recorded in the SSMP soon
after they occur.
3) LEGAL AUTHORITY
4) OPERATION AND MAINTENANCE PROGRAM
a) Maintain an up-to-date map of the sanitary sewer system showing all
gravity line segments and manholes, pumping facilities, pressure pipes
and valves, and applicable storm water conveyance facilities.
Our map books are concise and kept up to date. When mistakes are
found they are reported to GIS and updated pages are given out.
b) Describe routine preventative operation and maintenance activities by
staff and contractors, including a system for scheduling regular
maintenance and cleaning of 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.
The sewer system cleaning is on track, all sewers continue to be cleaned
annually. Enhanced maintenance areas are cleaned on a more frequent
basis; 32 are cleaned monthly and 26 are cleaned quarterly. All PM work
is recorded daily and tabulated monthly. We track the percentage of the
year we are at with the percentage of expected cleaning completed. This
way we are able to ensure we are on track to meet our goals and make
any needed adjustments to the program.
c) Develop a rehabilitation and replacement plan to identify and prioritize
system deficiencies and implement short-term and long-term
rehabilitation actions to address each deficiency. The program should
include regular visual and TV inspections of manholes and sewer pipes,
and a system for ranking the condition of sewer pipes and scheduling
rehabilitation. Rehabilitation and replacement should focus on sewer
pipes that are at risk of collapse or prone to more frequent blockages
due to pipe defects. Finally, the rehabilitation and replacement plan
should include a capital improvement plan that addresses proper
management and protection of the infrastructure assets. The plan shall
include a time schedule for implementing the short and long-term plans
plus a schedule for developing the funds needed for the capital
improvement plan.
We try to use our CCTV vehicle on a daily basis. We are getting a lot
more down time on the vehicle due mainly to problems with the camera
and associated equipment. This down time has an effect on the footage
we televise during the year.
Any defects we find that we consider to be severe enough to cause leaks,
or have the ability to compromise the integrity of the pipe, are repaired
immediately. The decision on whether to replace the damaged section
of pipe or to slip line from manhole to manhole is based on several
factors. If the pipe is over ten feet deep we would slip line. If there is
more than one break in a section we would slip line. If the main runs
under property we would have difficulty accessing we would slip line.
d) Provide training on a regular basis for staff in sanitary sewer system
operations and maintenance, and require contractors to be
appropriately trained.
Staff regularly attend classes and seminars put on by CWEA and SARBS.
They are encouraged to continue to educate themselves and to upgrade
certification.
e) Provide equipment and replacement part inventories, including
identification of critical replacement parts.
Critical replacement parts are kept in the warehouse.
5) DESIGN AND PERFORMANCE PREVISIONS
a) Design and construction standards and specifications for the
installation of new sanitary sewer systems, pump stations and other
appurtenances; and for the rehabilitation and repair of existing
sanitary sewer systems.
Can be found in ‘Standard Specs’.
b) Procedures and standards for inspecting and testing the installation of
new sewers, pumps, and other appurtenances and for rehabilitation
and repair projects.
Can be found in ‘Standard Specs’.
6) OVERFLOW EMERGENCY RESPONSE PLAN
a) Proper notification procedures so that the primary responders and
regulatory agencies are informed of all SSOs in a timely manner.
Our notification procedures have worked well in all SSOs we have
experienced. All agencies have been informed of any spill within the
required time. The system in place to get primary responders to any
spill ASAP works well. Whether the call comes from the answering
service or the District’s customer service personnel, field operators are
on scene within an acceptably short period of time.
b) A program to ensure an appropriate response to all overflows.
See comments above.
c) 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 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.
These procedures were put in place at the writing of the SSMP and are
still active.
d) Procedures to ensure that appropriate staff and contractor personnel
are aware of and follow the Emergency Response Plan and are
appropriately trained.
We could improve on this. I have sent copies of the Sanitary Sewer
Overflow Response Plan to all crew members and will have them read
annually.
e) Provide emergency operations, such as traffic and crowd control and
other necessary emergency response.
Traffic control is practiced almost daily by our crews. This ranges from a
single vehicle working on a manhole to multiple vehicles working on a
major highway. We have had no need for crowd control other than
pedestrian safety around the work area. Should the need arise I am
confident we will take the correct action to ensure the safety of the
public and our employees. We have a traffic control safety class
annually.
f) A program to ensure that all reasonable steps to contain and prevent
the discharge of untreated and partially treated wastewater to waters
in the United States and to minimize or correct any adverse impact on
the environment resulting from the SSO, including such accelerated or
additional monitoring as may be necessary to determine the nature
and impact of the discharge.
This program is in place and is followed when we have an SSO. Every
effort is made by the crews on site to contain the spill.
7) FOG CONTROL PROGRAM
a) An implementation plan and a schedule for a public education
outreach program that promotes proper disposal of FOG.
We continue to operate our fog program successfully, we think. We
have no major areas of grease build up in the sewer lines and no spills
have been caused by this. The biggest problem we seem to have is
non-payment of fees from some of our customers.
b) A plan and a schedule for the disposal of FOG generated within the
sanitary sewer system 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.
YLWD does not have this list. It is assumed that FSEs know who to call
to dispose of FOG. It may be that Orange County Sanitation District has
a list of acceptable disposal facilities.
c) The legal authority to prohibit discharges to the system and identify
measures to prevent SSOs and blockages by FOG.
Ordinance 04-01 is still in place and covers this. It has to be said,
though, that no action is taken against known FOG discharging FSEs.
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.
Ordinance 04-01 covers this.
e) Authority to inspect grease producing facilities, enforcing authorities,
and whether the enrolee has sufficient staff to inspect and enforce
the ordinance.
Ordinance 04-01 covers this.
f) An identification of sanitary sewer system sections subject to FOG
blockages, and establishment of a cleaning maintenance schedule for
each section.
We have established a list of sewer mains subject to FOG discharge.
These areas are cleaned on a regular basis. At present we have 15 FSEs
that discharge FOG into the sewer system.
g) Development and implementation of source control measures for all
sources of FOG discharged to the sanitary sewer system for each
section identified.
8) SYSTEM EVALUATION AND CAPACITY ASSURANCE PLAN
a) Evaluation.
The sewer master plan update has been contracted out and is in the
process of being completed.
b) Design criteria.
See above.
c) Capacity enhancement measures.
See above.
d) Schedule.
See above.
9) MONITORING, MEASUREMENT AND PROGRAM MODIFICATIONS
Since implementation of this plan it has been updated several times.
10) SSMP PROGRAM AUDITS
This is the fourth audit we have completed. Audits will be completed every
two years.
11) COMMUNICATION PROGRAM
The Enrolee shall communicate on a regular basis with the public on the
development, implementation, and performance of the SSMP. The
communication system shall provide the public the opportunity to provide
input to the Enrolee as the program is developed and implemented.
The Enrolee shall create a plan of communication with systems that are
tributary and/or satellite to the Enrolee’s sanitary sewer system.
The only thing we have done in this regard is to put the plan on our web
site. We do not communicate regularly with customers about the plan. We
do, however, answer any questions customers may have and these are
usually asked during a spill.
SEWER SYSTEM MANAGEMENT PLAN
SELF ASSESSMENT
January/February 2019
1) Goal.
The goal of the SSMP is to provide a plan and schedule to properly
manage, operate, and maintain all parts of the sanitary sewer system.
This will help reduce and prevent SSOs, as well as mitigate any SSOs that
do occur.
Since the last audit in 2017 we have had 2 spills. One of these caused by
vandalism, was a category 3, and the other a category 1, was by grit. Total
volume of the two spills was around 900 gallons. Fifty percent of the
discharge was recovered, and the category 1 line has been added to our
monthly check list.
We meet our system goals each year, cleaning all of the system and
televising one fifth of the system.
With the installation of a new gravity flow main, one of our two lift stations
has been eliminated. We also have an approved budget to add another
camera truck this year.
2) ORGANIZATION
a) The name of the responsible or authorized representative as
described in Section J of this Order.
Nothing has changed here, personnel names may have changed but job
title responsibilities remain the same.
b) The names and telephone numbers for management, administrative,
and maintenance positions responsible for implementing specific
measures in the SSMP program. The SSMP must identify lines of
authority through the organization chart or similar document with a
narrative explanation.
Any changes in personnel information are recorded in the SSMP soon
after they occur.

4) OPERATION AND MAINTENANCE PROGRAM
a) Maintain an up-to-date map of the sanitary sewer system showing all
gravity line segments and manholes, pumping facilities, pressure pipes
and valves, and applicable storm water conveyance facilities.
Our map books are concise and kept up to date. When mistakes are
found they are reported to GIS and updated pages are given out.
b) Describe routine preventative operation and maintenance activities by
staff and contractors, including a system for scheduling regular
maintenance and cleaning of 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.
The sewer system cleaning is on track, all sewers continue to be cleaned
annually. Enhanced maintenance areas are cleaned on a more frequent
basis; 33 are cleaned monthly and 25 are cleaned quarterly. All PM work
is recorded daily and tabulated monthly. We track the percentage of the
year we are at with the percentage of expected cleaning completed. This
way we are able to ensure we are on track to meet our goals and make
any needed adjustments to the program.
c) Develop a rehabilitation and replacement plan to identify and prioritize
system deficiencies and implement short-term and long-term
rehabilitation actions to address each deficiency. The program should
include regular visual and TV inspections of manholes and sewer pipes,
and a system for ranking the condition of sewer pipes and scheduling
rehabilitation. Rehabilitation and replacement should focus on sewer
pipes that are at risk of collapse or prone to more frequent blockages
due to pipe defects. Finally, the rehabilitation and replacement plan
should include a capital improvement plan that addresses proper
management and protection of the infrastructure assets. The plan shall
include a time schedule for implementing the short and long-term plans
plus a schedule for developing the funds needed for the capital
improvement plan.
We are using our CCTV truck on a daily basis.
Any defects we find that we consider to be severe enough to cause leaks,
or have the ability to compromise the integrity of the pipe, are repaired
immediately. The decision on whether to replace the damaged section
of pipe or to slip line from manhole to manhole is based on several
factors. If the pipe is over ten feet deep we would slip line. If there is
more than one break in a section we would slip line. If the main runs
under property we would have difficulty accessing we would slip line.
We have been doing more slip lining in-house. This has allowed more in
the budget for contracted manhole spraying for roaches as needed.
d) Provide training on a regular basis for staff in sanitary sewer system
operations and maintenance, and require contractors to be
appropriately trained.
Staff regularly attend classes and seminars put on by CWEA and SARBS.
They are encouraged to continue to educate themselves and to upgrade
certification.
e) Provide equipment and replacement part inventories, including
identification of critical replacement parts.
Critical replacement parts are kept in the warehouse.
5) DESIGN AND PERFORMANCE PREVISIONS
a) Design and construction standards and specifications for the
installation of new sanitary sewer systems, pump stations and other
appurtenances; and for the rehabilitation and repair of existing
sanitary sewer systems.
Can be found in ‘Standard Specs’.
b) Procedures and standards for inspecting and testing the installation of
new sewers, pumps, and other appurtenances and for rehabilitation
and repair projects.
Can be found in ‘Standard Specs’.
6) OVERFLOW EMERGENCY RESPONSE PLAN
a) Proper notification procedures so that the primary responders and
regulatory agencies are informed of all SSOs in a timely manner.
Our notification procedures have worked well in all SSOs we have
experienced. All agencies have been informed of any spill within the
required time. The system in place to get primary responders to any
spill ASAP works well. Whether the call comes from the answering
service or the District’s customer service personnel, field operators are
on scene within an acceptably short period of time.
b) A program to ensure an appropriate response to all overflows.
See comments above.
c) 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 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.
These procedures were put in place at the writing of the SSMP and are
still active.
d) Procedures to ensure that appropriate staff and contractor personnel
are aware of and follow the Emergency Response Plan and are
appropriately trained.
We are improving on this. I have sent copies of the Sanitary Sewer
Overflow Response Plan to all crew members and will have them read
annually.
e) Provide emergency operations, such as traffic and crowd control and
other necessary emergency response.
Traffic control is practiced almost daily by our crews. This ranges from a
single vehicle working on a manhole to multiple vehicles working on a
major highway. We have had no need for crowd control other than
pedestrian safety around the work area. Should the need arise I am
confident we will take the correct action to ensure the safety of the
public and our employees. We have a traffic control safety class
annually.
f) A program to ensure that all reasonable steps to contain and prevent
the discharge of untreated and partially treated wastewater to waters
in the United States and to minimize or correct any adverse impact on
the environment resulting from the SSO, including such accelerated or
additional monitoring as may be necessary to determine the nature
and impact of the discharge.
This program is in place and is followed when we have an SSO. Every
effort is made by the crews on site to contain the spill.
7) FOG CONTROL PROGRAM
a) An implementation plan and a schedule for a public education
outreach program that promotes proper disposal of FOG.
We continue to operate our fog program successfully, we think. We
have no major areas of grease build up in the sewer lines and no spills
have been caused by this. The biggest problem we seem to have is
non-payment of fees from some of our customers. We have met with
Orange County Sanitation District to review our FOG program and to
clarify jurisdiction.
b) A plan and a schedule for the disposal of FOG generated within the
sanitary sewer system 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.
YLWD does not have this list. It is assumed that FSEs know who to call
to dispose of FOG. It may be that Orange County Sanitation District has
a list of acceptable disposal facilities.
c) The legal authority to prohibit discharges to the system and identify
measures to prevent SSOs and blockages by FOG.
Ordinance 04-01 is still in place and covers this. It has to be said,
though, that no action is taken against known FOG discharging FSEs.
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.
Ordinance 04-01 covers this.
e) Authority to inspect grease producing facilities, enforcing authorities,
and whether the enrolee has sufficient staff to inspect and enforce
the ordinance.
Ordinance 04-01 covers this.
f) An identification of sanitary sewer system sections subject to FOG
blockages, and establishment of a cleaning maintenance schedule for
each section.
We have established a list of sewer mains subject to FOG discharge.
These areas are cleaned on a regular basis. At present we have 15 FSEs
that discharge FOG into the sewer system.
g) Development and implementation of source control measures for all
sources of FOG discharged to the sanitary sewer system for each
section identified.
8) SYSTEM EVALUATION AND CAPACITY ASSURANCE PLAN
a) Evaluation.
The sewer master plan update has been contracted out and is in the
process of being completed.
b) Design criteria.
See above.
c) Capacity enhancement measures.
See above.
d) Schedule.
See above.
9) MONITORING, MEASUREMENT AND PROGRAM MODIFICATIONS
Since implementation of this plan it has been updated several times.
10) SSMP PROGRAM AUDITS
This is the fifth audit we have completed. Audits will be completed every
two years.
11) COMMUNICATION PROGRAM
The Enrolee shall communicate on a regular basis with the public on the
development, implementation, and performance of the SSMP. The
communication system shall provide the public the opportunity to provide
input to the Enrolee as the program is developed and implemented.
The Enrolee shall create a plan of communication with systems that are
tributary and/or satellite to the Enrolee’s sanitary sewer system.
The only thing we have done in this regard is to put the plan on our web
site. We do not communicate regularly with customers about the plan. We
do, however, answer any questions customers may have and these are
usually asked during a spill.
SEWER SYSTEM MANAGEMENT PLAN
SELF ASSESSMENT
January/February 2021
1) Goal.
The goal of the SSMP is to provide a plan and schedule to properly
manage, operate, and maintain all parts of the sanitary sewer system.
This will help reduce and prevent SSOs, as well as mitigate any SSOs that
do occur.
Since the last audit in 2019, we had two spills. One was a category 3 spill
caused by roots with a volume around 625 gallons, this line has been added
to our enhanced maintenance list. The second was a category 1 spill of 175
gallons caused by a paving contractor issue.
We meet our system goals each year, televising one fourth of the system,
cleaning the enhanced maintenance areas every month or quarterly, and
the rest of the system as needed.
With the installation of a new gravity flow main, one of our two lift stations
was eliminated and the remaining station relined this year. We also added
another camera truck and a hand held pole camera system.
2) ORGANIZATION
a) The name of the responsible or authorized representative as
described in Section J of this Order.
Nothing has changed here, personnel names may have changed but job
title responsibilities remain the same.
b) The names and telephone numbers for management, administrative,
and maintenance positions responsible for implementing specific
measures in the SSMP program. The SSMP must identify lines of
authority through the organization chart or similar document with a
narrative explanation.
Any changes in personnel information are recorded in the SSMP soon
after they occur.
3) LEGAL AUTHORITY
4) OPERATION AND MAINTENANCE PROGRAM
a) Maintain an up-to-date map of the sanitary sewer system showing all

maintenance areas are cleaned on a more frequent basis; 71 are cleaned
monthly and 60 are cleaned quarterly. All PM work is recorded daily and
tabulated monthly. We track the percentage of the year we are at with
the percentage of expected CCTV completed. This way we are able to
