TITLE: Adoption of 2019 Sewer System Management Plan Update
ABSTRACT:
Per the requirements of the State Water Resources Control Board, every wastewater
agency is required to adopt a Sewer System Management Plan. The plan is an overview
of the City's procedures, protocols, and best management practices that minimize
Sanitary Sewer Overflows (SSOs). An update of the SSMP is required every five years
and the current 2019 SSMP is presented for City Council approval.
RECOMMENDATION:
a) Determine this action is exempt from the California Environmental Quality Act (CEQA)
pursuant to Sections 15060(c)(2) and 15060(c)(3) of the CEQA Guidelines because
this action will not result in a physical change to the environment, directly or indirectly;
and
b) Adopt the City's 2019 Sewer System Management Plan as required by the State
Water Resources Control Board.
FUNDING REQUIREMENTS:
The adoption of the Sewer System Management Plan itself does not require any specific
funding. However, the SSMP reinforces the City's need to maintain, operate and invest
in its wastewater collection system to prevent sewer overflows. The annual operational
expense is approximately $4 million and an additional $1.4 million is budgeted for capital
improvements in Fiscal Year 2019-20.
DISCUSSION:
A sanitary sewer overflow (SSO) is any overflow, spill, release, discharge of untreated
wastewater from a sanitary sewer system. SSOs often contain high levels of suspended
solids, pathogenic organisms, and pollutants. SSOs threaten public health, adversely
affect aquatic life, and impair the recreational use and aesthetic enjoyment of surface
waters including the closure of beaches and other recreational areas.

The Utilities Department operates and maintains the City's wastewater system consisting
of over 200 miles of sewer mains, 25,000 lateral connections, and 21 pump (lift) stations.
Maintaining the wastewater system at a high level is of the utmost importance for the
Department. All of the City's wastewater is conveyed to Orange County Sanitation
District's (OCSD) pump stations. The wastewater is treated at OCSD's Plant No. 2
located at the northwest corner of the Pacific Coast Highway and the Santa Ana River.
On May 2, 2006, the State Water Resources Control Board (SWRCB) adopted Order
Number 2006-0003-DWQ. As one of the requirements of the Order (a permit to operate),
City Council was required to approve a Sewer System Management Plan (SSMP) by
August 2, 2009. Council adopted the City's SSMP on July 28, 2009. City Council also
adopted the update on July 8, 2014. The intent of the SSMP is to provide a framework
and details, for managing the City's sewer system to eliminate overflows.
The 2019 SSMP has been updated and includes the following elements: Goals;
Organization; Legal Authority; Operations & Maintenance; Design and Performance
Provisions; Overflow Emergency Response Plan; Grease and Fat Control Plan; System
Evaluation and Capacity Assurance Plan; SSMP Program Audits; and Communications.
The attached 2019 SSMP is the final version incorporating current changes, best
practices and industry recommendations. Per SWRCB, the 2019 SSMP is to be
approved by the City Council. The City is currently abiding by all of the plan's
requirements and is in full compliance.
ENVIRONMENTAL REVIEW:
Staff recommends the City Council find this action is not subject to the California
Environmental Quality Act (CEQA) pursuant to Sections 15060(c)(2) (the activity will not
result in a direct or reasonably foreseeable indirect physical change in the environment)
and 15060(c)(3) (the activity is not a project as defined in Section 15378) of the CEQA
Guidelines, California Code of Regulations, Title 14, Chapter 3, because it has no
potential for resulting in physical change to the environment, directly or indirectly.
NOTICING:
The agenda item has been noticed according to the Brown Act (72 hours in advance of
the meeting at which the City Council considers the item).

SEWER SYSTEM MANAGEMENT PLAN
Introduction
The State Water Quality Control Board ("State Board") regulates and oversees water
quality in California including the shoreline and Upper and Lower Newport Bay. In the
past, beaches along the coast have been closed numerous times due to contaminated
surface water runoff and wastewater spills (also known as sanitary sewer overflows or
"SSOs") and the closures impacted the economy associated with summer beach
activities.
In 2006, in response to the beach closures, the State Board adopted General Waste
Discharge Requirements (WDRs) for the operation of sewage collection systems. The
WDRs apply to all the sewer system owners or operators in California who operate a
sanitary sewer system 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. Therefore, these regulations apply directly to the City of Newport
Beach and its collection system.
One of the requirements of the WDRs is preparation and implementation of a Sewer
System Management Plan (SSMP). By preparing and practicing the procedures in the
plan, SSOs should decrease or stop entirely. The City believes that it is currently
adhering to all of the SSMP requirements due to the City's history of taking a proactive
approach to sewer system management. The City completed its Sewer Master Plan in
July 2009.
On July 28, 2009, the Utilities Department recommended that the City Council formally
adopt the SSMP, directing the Department to continually update the plan and bring it
back to Council at appropriate intervals for additional consideration and approval. The
SSMP was subsequently updated in July 2014 and adopted by City Council on July 8,
2014. This 2019 SSMP is scheduled to be approved by City Council on November 19,
2019.

Section I Sewer Svstem Manaaement Plan Goals:
The General Waste Discharge Requirements for the Goals section of the Sewer System
Management Plan state that the City must develop goals to properly manage, operate,
and maintain all parts of its wastewater collection system in order to reduce and prevent
SSOs, as well as to mitigate any SSOs that occur.
The main goal of the Sewer System Management Plan (SSMP) is to provide a plan and
schedule to properly manage, operate, and maintain all parts of the sanitary sewer
system. This will help reduce and prevent SSOs, as well as mitigate any SSOs that do
occur. The City of Newport Beach recognizes the importance of protecting public health
and ocean water quality by preventing sewer spills. The City supports the Waste
Discharge Requirements (WDRs) for the operation of sewage collection systems.
In order to minimize sanitary sewer overflows (SSOs) and mitigate the effects of SSOs
that may occur, the goals of the City of Newport Beach Sewer System Management
Plan are to:
1. Maintain uninterrupted sewage flow without health hazard, effluent leakage, or
water infiltration and inflow.
2. Operate a sanitary sewer system that meets all regulatory requirements.
3. Avoid sanitary sewer overflows and respond to sanitary sewer overflows
quickly and mitigate any impact of the overflow.
4. Maintain standards and specifications for the installation of new wastewater
systems.
5. Verify the wastewater collection system has adequate capacity to convey
sewage during peak flows.
6. Provide training for Wastewater Collection staff.
7. Maintain the Fats, Oil, and Grease program (FOG program) to limit fats, oils,
grease, and other debris that may cause blockages in the wastewater collection
system.
8. Identify and prioritize structural deficiencies and implement short-term and
long-term maintenance and rehabilitation actions to address each deficiency.
9. Meet all applicable regulatory notification and reporting requirements.
10. Provide excellent customer service through efficient system operation and
effective communication strategies.

EMERGENCY RESPONSE PROGRAM RESPONSIBILITIES
Utilities Director The Utilities Director oversees the implementation of the SSMP
including providing staff and other resources necessary to
operate and maintain the sanitary sewer system. The Utilities
Director also coordinates with the Public Works Department to
implement sewer -related projects as part of the City's Capital
Improvement Program. The Utilities Director ensures that line -
response personnel have all funding and authority needed to
effectively act on their obligations under the SSMP. The
Director provide policy guidance where needed.
Utilities Manager The Utilities Manager provides direction and feedback to the
Utilities Supervisor regarding operational needs and
requirements. The Utilities Manager oversees implementation of
operation and maintenance elements of the SSMP including
reviewing daily maintenance activities and managing the City's
asset maintenance management system. The Manager
supports the Utilities Supervisor and field crews.
Utilities Supervisor The Utilities (Wastewater) Supervisor directs field crews with the
day-to-day operations and assignments of the Wastewater
Division and structures emergency response operations based
on experience and utilization of field staff available. The
Supervisor responds to SSO events.
Field Crews The Field Crews, (Utilities Crew Chiefs and Utilities Specialists,
etc) maintain the sewer system assets and responds to
emergency call outs. They implement emergency response
plans, mobilize sewer -cleaning trucks, by-pass equipment,
generators and maintain the City's sewer infrastructure.

(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 California Department of Public
Health and State Office of Emergency Services (OES)).
The Utilities Supervisor is responsible for overseeing the reporting
process. Utilities Department staff members enter information on spills in
the State's CIWQs database; a copy of the spill report is given to
Administrative staff, who in turn adds the spill to the required
spreadsheets. The Utilities Director reviews the draft with the Utilities
Supervisor. Consideration is given to volume calculations and vacuum
operations, cause of spill, timeliness of response, and any other
appropriate or required data. After review and revisions are completed,
the report is certified on the database and copies are transmitted to the
appropriate agencies. Normal procedure has always been for the City to
report all spills regardless of size and whether or not the spill reaches
waters of the State. The City believes in keeping the reporting agencies
and the public fully informed.
As a first priority during a sewer spill, City staff (typically the Utilities
Wastewater Supervisor) notifies the appropriate agencies by phone of a
SSO instead of depending on the report as a means of notification.

(III) Legal Authority.
The City 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 City.
(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.
The City complies with the legal authority requirements of the WDR. The City's legal
authorities are contained in the following documents:
• City of Newport Beach Municipal Code
• City of Newport Beach Standard Drawings and Standard Specifications
• Standard Specifications for Public Works Construction (Greenbook)
(a) Prevent illicit discharges into its sanitary sewer system
The City has the power to install sewers and enact regulations related
thereto, including the prohibition of private sewer systems and requiring all
inhabited property to be connected to City sewers. A permit from the City
is required to connect to, use, or maintain a connection to the City's sewer
facilities. Any person, firm or corporation that connects or discharges to
City's wastewater system without a valid permit are enforced through the
City's Code Enforcement. In the Newport Beach, illegal connections are
usually connections to the sewer system by property owners who have
drainage problems due to flat areas and low spots and who solve those
problems by draining those areas to an inlet that is connected to the sewer
system. When instances of these illegal connections are found, the
III Page
20-13
City of Newport Beach
2019 Sewer System Management Plan
property owner is required to immediately remove the connection through
a code enforcement process.
The City has established a long-range financial plan to ensure capital
replacement of the wastewater system. (2017 Sewer Rate Study)
The current Title 14 of the Municipal Code regulates sewer construction.
All sewer construction must be in accordance with City standards (Section
14.24). The inspection requirements by City staff are provided in Chapter
14.04.120.
The City continues its video inspection (CCTV) of all sewer mains in the
system. The results of the video inspection will show areas of sewer line
deficiencies including illicit connections and infiltration into the lines.
Legally controlling inflow encompasses controlling the major sources of
inflow: illegal connections, infiltration through cracked and damaged
pipelines and submerged or flooded streets causing water to enter the
"pick" holes in manhole covers. Illegal connections are usually
connections to the sewer system by property owners who have drainage
problems due to flat areas and low spots and who solve those problems
by draining those areas to an inlet that is connected to the sewer system.
When instances of these illegal connections are found, the homeowner is
required to immediately remove the connection. The City's sewer permit
issuance procedure is supported by ordinance and any illegal connections
are subject to citations.
By using the CCTV, the City is able to proactively look for infiltration of
roots and cracks in sewer pipelines. To address the hazard of submerged
or flooded streets, the City looked at the option of using watertight
manhole covers but it was dismissed because watertight manhole covers
are bolted down and become hard to remove during nighttime
emergencies and prevent the discharge of concrete damaging gasses.
121Page
20-14
City of Newport Beach
2019 Sewer System Management Plan
(b) Require that sewers and connections be properly designed and
constructed;
The City has its Standard Plans and Specifications for the Construction of
Sanitary Sewers, which insures the sewer lines and connections are
properly designed and constructed. The City's specifications by reference
incorporate the Standard Specifications for Public Works Construction
("The Greenbook"), which also helps insure proper design and
construction of sewer facilities. The City provides continuous inspection
during the installation procedure to insure the proper construction
practices are followed. The City also requires post construction CCTV to
additional insure proper construction.
The Public Works Department has five city inspectors and one contracted
inspector, each with numerous years of experience working for the City.
The Utilities Department also has one inspector with dedicated time
towards permit inspection of Utilities. All of the City's inspectors are
trained and experienced in pipeline and pump station construction. They
all attend training classes and educational seminars to stay familiar with
advancements in the industry. The inspectors maintain copies of the
City's Design Criteria, Standard Special Provisions and Standard
Drawings for Public Works Construction, Standard Specifications for
Public Works Construction, Inspection Manual, and the Work Area Traffic
Control Manual (WATCH), on the job at all times.
(c) Ensure access for maintenance, inspection, or repairs for portions of
the lateral owned or maintained by the Public Agency;
The City requires all new properties and existing properties that redevelop
to install a sewer cleanout at the property line (Municipal Code Section
14.24.020). These cleanouts are required at the time Building Permits are
issued. This cleanout provides access City for maintenance, inspection
and maintenance of the public portion of the lateral. The cleanouts are
131Page
20-15
City of Newport Beach
2019 Sewer System Management Plan
installed and inspected according to City Standards and are inputted into
the City's GIS system. As needed, the public portion of the laterals are
inspected by the City using the cleanout.
(d) Limit the discharge of fats, oils, and grease and other debris that
may cause blockages, and
The City adopted a revised Fats, Oils, and Grease (FOG) Ordinance to
reduce and control FOG in the City's sewer system. Grease has been
identified as a major cause of sewer line stoppages and spills by the City
and by the Orange County Grand Jury who conducted a countywide
study. Because of this finding, FOG has been identified as the most
important first step in improving sewer system reliability.
Pursuant to Chapter 14, Section 30 of the City of Newport Beach
Municipal Code, dedicated to Fats, Oil and Grease Control, the City has
the legal authority to control discharges to the sewer system for all sewer
facilities located on private property that are outside any structures located
on the property. This authority allows the City to require grease control
devices for certain food preparation facilities. The City through the use of
a contractor inspects all grease interceptors and all food service
establishments for compliance on a quarterly and annual basis
respectively. The contract FOG inspection program instructs Best
Management Practices to restaurants, specifically on how to prevent the
discharge of FOGs into the sewer system. This has been a very effective
tool for the City. If any food service establishments is not compliant with
the Code, they are inspected until compliance is achieved. Code
Enforcement is also a tool available to the City.
The legal authority for plumbing fixtures inside a building rests with the
City's Community Development Department and County Health Care
Authority and new facilities are require compliance with the City Code,
specifically the plumbing code and requirements for grease control

2019 Sewer System Management Plan
devices. City staff continuously works to modify and adopt policies, which
will be consistent with the goal of reducing or removing FOG from the
City's sewer system.
(e) Enforce any violation of its sewer ordinances.
The City of Newport Beach has a Municipal Code to enforce violations of
its sewer ordinances. The City Attorney has verified our legal authority for
inspection and enforcement. Any person, firm, or corporation violating the
provisions of Municipal Code are subject to administrative citations,
misdemeanor punishments, termination of service, and abatement of
conditions on property if necessary.

The locations of all storm water facilities are also included on separate
layers in the GIS. The City recognizes the link between a SSO and its
path of travel into the storm drain facility and ultimately to the receiving
waters. The City has educated its staff to understand the storm drain
network and utilize the network to capture a spill if it has entered the storm
drain system.
The City understands the National Pollutant Discharge Elimination System
(NPDES) regulations for storm drain system owners, including the
provisions of the MS4 Permit. The MS4 Permit contains requirements
prohibiting SSOs into the storm drains. The MS4 Permit requires the
storm drain system owners to adopt measures that will decrease the
possibility of SSOs. The City attends the meetings of the MS4 Permit Co -
Permittees in order to coordinate the effort of the storm drain and sewer
system owners. Many of the MS4 Permit's municipal obligations
(including storm drain system maintenance) are assigned to the City's
Storm Drain Division within the Utilities Department.
(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;
The City has historically cleaned the sewer system on a regular basis and
continues to do so today.
20-20
City of Newport Beach
2019 Sewer System Management Plan
Proactive Sewer Cleaning:
The City of Newport Beach proactively cleans the every gravity sewer pipe
segment in the wastewater collection system at least once every 18 -
months on a systematic cleaning cycle. The 18 -month systematic
cleaning cycle used for proactive sewer cleaning consists of cleaning
groups of pipes, organized by areas. The City uses three different vactor
cleaning trucks depending on the pipe and location. The variety of trucks
gives the City the respond and perform maintenance in small tight alleys
and easement areas. Crews also use root cutting nozzles and root
foaming products to control roots. The City has identified tree roots in
conjunction with grease as the primary cause of spills in the City. All
maintenance documentation is uploaded to the City's GIS system and the
electronic "Quest" service and work order request system. A low-tech
color -coded area map is also used which shows the date of the last
cleaning for the entire 18 month City-wide cleaning schedule. The more
vigilant the City is in taking a proactive stance to maintain the main line
sewer pipes, the more likely staff is to prevent problems and find problems
or areas of concern that need attention.

2019 Sewer System Management Plan
High Maintenance Areas and Preventative Maintenance Cleaning:
Areas needing more frequent cleaning — known as "high maintenance
areas" — are cleaned as frequently as monthly and quarterly. This
preventive maintenance sewer cleaning is utilized for sewer reaches with
a known history of one or more maintenance issues such as root intrusion,
grease accumulation, or debris deposition. These also include inverted
siphons that run under flood control channels and bay crossings or
commercial areas with multiple restaurants.
High Maintenance Area cleaning schedules include:
• Airport Area (Monthly)
• High Maintenance Area 1 (Monthly)
• High Maintenance Area 2 (Quarterly)
• Wet Wells (Every 3 Months)
• Traffic Control Areas (Every 6 months)
The City has one hydro truck and two combination hydro -vacuum trucks
specifically for spill cleanup, each with a two -person crew. The City also
has additional backup combination hydro -vacuum truck available for use
from the Storm Drain Division. The City sends out two crews daily,
sometimes three based on staff availability. Again, the City has areas of
monthly and quarterly cleaning. This proactive and preventative approach
helps the City stay informed of all areas of the City, especially the high
maintenance areas.
CCTV (Video taping)
The City utilizes in-house and contract services to video-tape (CCTV)
sewer lines to monitor the high maintenance areas annually, recent
repairs, and also to fulfill the goal of completing video inspections of all
sewer pipelines once every 10 years. Continuous inspection and post
201 Page

City of Newport Beach
2019 Sewer System Management Plan
construction video inspection of all utilities being installed near sewer lines
insures proper protection methods are provided for the sewer lines and
lengthens the life expectancy of those lines. After sewer lines are video
taped, they are rated on their condition of severity and prioritized as
described below.
Pump (Lift) Stations
4
• In addition to the daily cleaning of the gravity sewer lines by crews, the
Wastewater Crews maintain 21 sewer pump stations. A two -person pump
crew maintains the pumps and motors for all 21 sewer pump stations. The
City uses the recommended pump maintenance schedule for the piping,
valves, and other equipment in the station and valve vault provided by the
City's consultant Engineers Sales and Service Company (ESSCO) and
inspects every pump station at least once per week. ESSCO operates as
a primary contact for the City during emergencies. ESSCO have provided
this service to the City for the past 45 years as it relates to the equipment
at the City's sewer facilities. The City also uses SCADA and
communication systems to monitor pump station flow and receive alarms
21 jPage
20 -23
City of Newport Beach
2019 Sewer System Management Plan
for dispatching crews. Certain pump stations have emergency power
generators on site and emergency pumps and generators are housed by
the Utilities Department in the event of a failure.
CONSTRUCTION REPAIRS
The City also has and additional Wastewater crews that help maintain the
City's sewer infrastructure. This includes a two -person repair crew that
primarily installs, repairs or replaces sewer lines, sewer laterals, cleanout,
and manholes.
These crews are also available to assist on the additional hydro -vacuum
truck, as needed.
(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;

City of Newport Beach
2019 Sewer System Management Plan
The City's sewer system rehabilitation and replacement planning process
consists of systematic inspection and condition assessment of all pipe
reaches incorporated into a 30 -year Sewer System Master Plan approved
in 2010. The Master Plan identifies and prioritizes condition -related
repairs, rehabilitation, and replacement projects. The City's process is to
evaluate sewer system structural deficiencies identified through sewer
inspection and condition assessment to determine if a repair,
rehabilitation, or replacement project is required along with an appropriate
timeframe for addressing the structural issues identified. When new
deficiencies are found, they are either repaired on an emergency basis
and placed in the Capital Improvement Program queue based on it's
severity and priority.
The Public Works Department leads the implementation of the annual
Capital Improvement Program. It typically consists of a few pipeline and
lateral rehabilitation projects, replacement projects, and upgrade projects.
It also usually consists of one pump (lift) station rehabilitation or
improvement project. Sufficient funding is available in the Wastewater
Enterprise fund and has been secured by the 2017 Sewer Rate Study and
rate increases.
The City utilizes in-house and contract services to video-tape (CCTV)
sewer lines to monitor the high maintenance areas annually, recent
repairs, and also to fulfill the goal of completing video inspections of all
sewer pipelines once every 10 years. After sewer lines are video taped,
they are rated on their severity condition and prioritized using National
Pipeline Assessment Condition Program system standards. As described
above, if repairs are needed, they are then put into a repair priority
sequence.

The City uses a combination of on-the-job training, conferences, seminars,
and other training opportunities to provide technical training for its
wastewater collection system staff. The Department maintains a budget
for annual training consistent with the requirements placed on the City by
the State Water Resources Control Board in the Statewide General
Discharge Requirements for Sanitary Sewer Systems. This training
ensures that the Wastewater Collection Section staff maintain their
California Water Environment Association (CWEA) certifications and also
provides the opportunity to achieve advanced competency in the
profession.
In addition to technical training provided by outside resources, the City
provides in-house technical training for equipment and collection system
operations and maintenance. The focus on in-house training is hands-on
training at a work site. All employees receive thorough training on the
Department's SSMP, their roles and the roles of others. The Department
conducts table top exercises to reinforce this training. All employees are
241Page
20-26
City of Newport Beach
2019 Sewer System Management Plan
required to keep relevant portions of the SSMP with them at all
appropriate times.
The City requires all Wastewater personnel to have, at a minimum, Grade -
1 certification provided by the CWEA. The City requires all Wastewater
staff that cross -trains within our Maintenance & Repair (M&R) division or
chooses to take the after-hours duty to maintain a California Department
of Health Services ("DOHS") Grade D1 (WDO Certificate.) The pump
crew chief and several other staff have formalized training in the repair
and maintenance of the pumps. City staff is fully trained and capable of
making any repairs and responding to any and all emergencies due to the
cross training between the divisions. Currently the majority of the
Wastewater Division employees are certified at higher than Grade I
Collections. Wastewater employees completed confined space and trench
trainings, as well as certified CPR classes. The City also has three
emergency on-call contractors under contract who specialize in
wastewater, are appropriately trained and are available to respond to any
needed emergency.
(e) Provide equipment and replacement part inventories, including
identification of critical replacement parts.
MQ1�w�
251Page
20-27
City of Newport Beach
2019 Sewer System Management Plan
For the City, keeping critical replacement parts available encompasses
stocking spare pumps that can be used as replacements while pumps are
serviced or replaced. The City attempts to use the same model pumps in
as many stations as possible to simplify maintenance and replacement.
Twice yearly, staff inventories all piping supplies (VCP, & PVC pipe,
fittings & couplings), all main line sewer cleaning supplies (degreasers,
root cutters & saws, high pressure hoses, etc.), and pump station
replacement parts (glands, check valves & plug valves.)
The City has all the necessary equipment to work on sewer line
maintenance and repairs or pump station maintenance and repairs. In
addition to small tools, the City has a full fleet of equipment at its disposal.
The City also has mutual aid arrangements with neighboring waste water
cities and agencies.
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.
(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
The City's standards for the proper installation and inspection of sewer
lines are also discussed in Section (III) (b) above.
The City's Utilities, Public Works and Community Development
Departments require all new or rehabilitated sewer installations be tested
and inspected pursuant to the Municipal Code, the City's standard plans
and a permit is required for such connections. The primary design and
261Page
20-28
City of Newport Beach
2019 Sewer System Management Plan
performance standards the City's uses in design and installations of new
sewer systems are:
• City of Newport Beach Municipal Code
• City of Newport Beach Standard Drawings and Standard Specifications
• CIP project specific Special Provisions and Technical Specifications.
• Standard Specifications for Public Works Construction (Greenbook)
The standards listed above outline construction specifications for installing
new wastewater systems, pump stations, and other appurtenances; and
for rehabilitation and repair of existing wastewater systems. Design criteria
include specifications for items such as pipe materials, minimum sizes,
minimum cover, strength, minimum slope, trenching and backfill, structure
standards, and other related provisions. All new construction,
rehabilitation, or repair of the sanitary sewer system adheres to these
standards. In addition, the City will use additional written specifications
known as Special Provisions and Technical Specifications for specialized
construction or projects.
Additionally, the City has standardized its use of materials in the pumping
stations for ease of maintenance and replacement. This includes the
pumps, liquid level indicators, remote terminal units (RTU's), valves,
piping, and radios.
The City uses "no -dig" pipeline rehabilitation as often as possible. The
City considers no -dig technology an important tool in pipeline rehabilitation
as systems reach their life expectancy. Another important tool used by
the Department is vacuum excavation. The City still utilizes the standard
method of pipeline removal and replacement in conjunction with new
pipeline re -lining technologies.
271Page
20-29
City of Newport Beach
2019 Sewer System Management Plan
(b) Procedures and standards for inspecting and testing the installation
of new sewers, pumps, and other appurtenances and for
rehabilitation and repair projects.
The City's standard public works contract provides that work is not placed
into service and accepted by the City until inspection and testing is
completed. The City provides continuous inspection during the
construction of sewer facilities and believes that proper installation is the
key element to insure proper operation and maximum life expectancy.
City inspectors use the Greenbook Inspection Manual for reference.
Experience and training also allow them to provide excellent observation
of contractors' work. With regard to testing sewer lines, the City uses the
Greenbook recommended air -testing and video inspection procedures on
all new main lines and video inspects sewer lines after they are
constructed.
(VI) Overflow Emergency Response Plan:
Each Enrollee shall develop and implement an overflow emergency response
plan that identifies measurers 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)
verflows,(c) Procedures to ensure prompt notification to appropriate regulatory
agencies and other potentially affected entities of all SSOs
(d) Procedures to ensure that appropriate staff and contractor personnel
follow the Emergency Response Plan and are appropriately trained,-
(e)
rained,(e) Procedures to address emergency operations, such as traffic and crowd
control and other necessary emergency activities, and
(f) A program to ensure that all reasonable steps are taken to contain and
prevent the discharge of wastewater
20-30
City of Newport Beach
2019 Sewer System Management Plan
(a) Proper notification procedures so that the primary responders and
regulatory agencies are informed of all SSOs in a timely manner;
The City's goals with respect to responding to SSOs are to:
• Work safely;
• Respond quickly to minimize the volume of the SSO;
• Eliminate the cause of the SSO;
• Contain the spilled wastewater to the extent feasible;
• Prevent sewage system overflows or leaks from entering the storm
drain system or receiving waters to the maximum extent practicable;
• Minimize public contact with the spilled wastewater;
• Mitigate the impact of the SSO; and
• Meet the regulatory reporting requirements.
Sewer service calls are high priority events that demand a prompt
response to the location of the problem. Upon notification of a potential
sewer overflow, the City's Duty Responder shall be dispatched onsite
within 30 minutes. In the case of an overflow, the City will dispatch the
appropriate crews to investigate, identify the cause, and provide
appropriate action to minimize the effects of the overflow on public health
and quality of surface waters.
Normal Work Hours
Utilities Department (949) 644-3011
The normal working hours for Utilities Department staff and for answering
emergency calls is from 7:00 am to 4:30 pm Monday through Thursday
and 7:00 am to 3:30 pm every Friday. When a report of an SSO is made,
the office staff takes the information from the caller and communicates this
information to Wastewater field crew staff and to the Wastewater
Supervisor (or to the person in charge of the Wastewater Maintenance
Division when the superintendent is on leave.) The wastewater field crew
staff and the Wastewater Supervisor (or the person in charge) will report
to the site to assess the situation and take appropriate action.
MR03M
20-31
City of Newport Beach
2019 Sewer System Management Plan
After Hours: Police Department's Dispatch (949) 644-3717
Outside of regular business hours, all emergencies calls go through the
Police Department's Dispatcher desk. After hours, the emergency
standby duty personnel will be reached by PD Dispatch. Emergency
stand-by duty personnel are on-call after hours and carry a City pager and
City cell phone for ease of access by the Police Department after hours.
Duty personnel have equipment and tools in duty truck to respond to
SSO's
Duty staff will perform initial assessment either through phone call
interview or initial site assessment. If upon arrival or in route to the scene
of the SSO and duty staff determines the SSO to be in a City sewer main,
staff will respond or coordinate a response with the City Vactor trucks and
take appropriate action. If there is a sewer alarm from one of the sewer
pumping stations, Duty and a separate Water Production duty staff will
receive the alarm via pager, cellular phone and email. Using the City's
SCADA system, staff can assess the situation quickly.
The City's afterhours approach to sewer overflow response is to include
employees with different skill sets on the call out list enabling the City to
respond quickly and effectively to a variety of emergencies involving
sewer pipelines or sewer pump stations.
(b) A program to ensure an appropriate response to all overflows;
City policy is to respond to all spills within the city — and even provide
mutual aid outside the City limits — whether on public or private property
and to take all steps possible to prevent the spills from reaching the storm
drains, flood control channels, or waters of the State, all in accordance
with the waste discharge requirements. Section (II) Organization of this
document details the lines of authority and responsibilities of City
personnel during an emergency. Since Utilities Department staff cross -
301 Page
20-32
City of Newport Beach
2019 Sewer System Management Plan
train between Wastewater and Water Maintenance & Repair, there are
plenty of trained and qualified staff to assist at any time with SSOs.
Typical Response Steps:
• Identify and assess the affected area and extent of spill. If possible, take
photographs to document the extent of the spill.
• Use best judgment to determine whether to proceed immediately with
blockage removal versus containment. The guidance for this decision is:
■ Small spills — proceed with immediate containment measures near
the appearance point followed by blockage removal.
■ Moderate or large spill where containment is anticipated to be
simple — proceed with immediate containment measures near the
appearance point followed by blockage removal.
■ Moderate or large spills where containment is anticipated to be
difficult — proceed with clearing the blockage; however, call for
additional assistance immediately to focus on implementing
containment measures.
• Restore Flow using the appropriate cleaning tools; set up downstream of
the blockage and hydro clean upstream from a clear manhole. Attempt to
remove the blockage from the system and observe the flows to ensure
that the blockage does not recur downstream.
■ If the blockage cannot be cleared within a reasonable time (15
minutes), or the sewer requires construction repairs to restore flow,
then initiate additional containment measures and/or bypass
pumping.
■ If assistance is required, contact other employees, contractors, and
equipment suppliers.
o Initiate Spill Containment Measures. The responding crew should attempt
to contain as much of the spilled sewage as possible using the following
steps:
■ Determine the immediate destination of the overflowing sewage.
311 Page
20-33
City of Newport Beach
2019 Sewer System Management Plan
■ Implement immediate containment measures consisting of plugging
storm drains using sandbags, plastic sheeting, and/or other dam
construction material to contain the spill, whenever appropriate.
■ Additional containment measures include containing/directing the
spilled sewage using dike/dam, sandbags, or earthen berms in
landscaped or undeveloped areas.
■ Pump around the blockage/pipe failure to convey the wastewater
to the nearest downstream manhole or facility.
■ If the spill is caused by a sewer lateral, City staff may shut off the
water supply to that property when the wastewater endangers the
public health.
o Recovery and Clean Up: The recovery and clean up phase begins when
the flow has been restored and the spilled sewage has been contained to
the extent possible. The SSO recovery and clean up procedures include
the steps below:
■ Estimate the Volume of Spilled Sewage: Use the State methods to
estimate the volume of the spilled sewage. If possible, utilize
available information such as pump station run times and SCADA
data to support or validate volume estimates. Document the
estimate using photos of the SSO site before and during the
recovery operation
■ Recovery of Spilled Sewage. Vacuum up spilled sewage using the
hydro%ombo unit or pump the spilled sewage and any water used
to flush the area and discharge it back into the wastewater
collection system
■ Clean Up and Disinfection. Implement clean up and disinfection
procedures to reduce the potential for human health issues and
adverse environmental impacts that are associated with an SSO
event. Where clean-up is beyond the resources or capabilities of
staff, the City may use a contractor to support clean-up operations.
■ Hard Surface Areas: Take reasonable steps to contain and vacuum
up the wastewater and return it to the wastewater collection
system. Collect all signs of sewage solids and sewage -related
material either by hand or with the use of rakes and brooms. Wash
321Page
20-34
City of Newport Beach
2019 Sewer System Management Plan
down the affected area with high pressure water using nozzles on
provided on the hydro%ombo unit and vacuum the wash water
utilizing the hydro%ombo unit. Allow area to dry.
■ Storm Drain System: If sewage has reached the storm drain
system, the hydro%ombo unit should be used to vacuum/pump out
the catch basin. Flush the storm drain system with wash water and
capture all residual wash water at a point of containment
downstream. In the event that an overflow occurs at night, inspect
the location early on the following morning. The operator should
look for any signs of sewage solids and sewage -related material
that may warrant additional cleanup activities.
(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:
The City's policy is to report all spills, regardless of size, to the Regional
Board, the Department of Public Health, and Cal EMA, whether on public
or private property, even if the spill is completely contained. The City
believes in full disclosure of its operations and performance. The City
adopted and uses the State's spill reporting program.
Oral Notification:
As a first priority during a Category 1 sewer spill, the Wastewater
Supervisor or designated response staff will immediately notify the
California Office of Emergency Services (Cal-OES) (not later than two
hours after becoming aware of the discharge) by phone that a spill has
occurred. The Wastewater Supervisor will then notify Orange County
Health Care Agency (OCHCA), Orange County Public Works and the
Santa Ana Regional Water Quality Control Board. The City notifies
331Page
20-35
City of Newport Beach
2019 Sewer System Management Plan
OCHCA by phone on all private property spills that are not fully
recoverable immediately upon discovery.
Category 1 sewer spills are spills from City's sanitary sewer system of any
volume that:
a. Reach surface water and/or reach a drainage channel tributary
to a surface water;
b. Reach a Municipal Separate Storm Water System (MS4) and is
not fully captured and returned to the sanitary sewer system or
not otherwise captured and disposed of properly.
Each of the following will be notified in the case of a Category 1 sewage spill:
Cal-OES (800) 852-7550 (within two hours after being notified of the spill)
OCHCA (714) 628-7008
RWCQB (951) 782-4130 Fax: (951) 781-6288
OCPW (877) 897-7455
Category 2 spills are discharges of untreated or partially treated
wastewater of equal or greater than 1,000 gallons that did not reach
surface water, a drainage channel, or a MS4 unless the entire SSO
discharged to the storm drain system is fully recovered and disposed of
properly.
Category 3 spills are all other discharges of sewage that result from a
failure in the Agency's sanitary sewer system.
Written Reports:
For Category 1 spills, the City will adhere to the following written procedures:
• Within 24 hours of notification of a Category 1 spill, the City will certify to
the appropriate RWQCB, by phone or with a follow up fax, that Cal-OES
and OCHCA were notified.
• Within 3 business days of being notified of the spill event, the City will
certify the initial report using the CIWQS online SSO Reporting System
341 Page
20-36
City of Newport Beach
2019 Sewer System Management Plan
Within 15 calendar days of the conclusion of the SSO response and
remediation, the City will certify the final report using the CIWQS online
SSO Reporting System.
• The City will update CIWQS and re -certify the SSO report as new or
changed information becomes available. The updates will be submitted
as soon as new information is verified. All updated reports will be
certified.
For Category 2 spills, The City will adhere to the following written procedures:
• Within 3 business days of being notified of the spill event, The City will
certify the initial report using the CIWQS online SSO Reporting System.
• Within 15 calendar days of the conclusion of the SSO response and
remediation, the City will certify the final report using the CIWQS online
SSO Reporting System.
• The City will update CIWQS and re -certify the SSO report as new or
changed information becomes available. The updates will be submitted
as soon as new information is verified. All updated reports will be
certified.
For Category 3 spills, the City will adhere to the following written procedures:
• Within 30 calendar days after the end of the calendar month in which the
SSO occurred, the City will submit a certified report using the Online
SSO Reporting System. The report will include the information to meet
the WDR requirements.
(d) Procedures to ensure that appropriate staff and contractor personnel
are aware of and follow the Emergency Response Plan and are
appropriately trained;
All Wastewater Division personnel, who have a role in responding to,
reporting, and/or mitigating a wastewater collection system overflow
receive annual training. The training includes emergency operations, such
as traffic and crowd control, procedures for volume estimation and SSO
start time determinations. Periodic field drills and exercises are conducted
to assure the Wastewater Division personnel practice under actual
conditions.
351Page
20-37
City of Newport Beach
2019 Sewer System Management Plan
The role of each person during an emergency has been established. The
City has pre -established responsibilities for administrative staff members
(EOC, DOC) that work concurrently with the field crews to provide an
efficient response. Field crewmembers are required to keep copies of the
Sewer System Management Plan and the spill reporting form in their
vehicle.
If the emergency is during normal working hours, field crews and the
supervisor will work appropriately to handle the emergency. City Staff is
positioned as follows:
• The Wastewater Utilities Supervisor is in the field, documenting the
situation with pictures and verbal reports back to the administrative staff
in the office. The Utilities Supervisor will verbally report any sewer spills
to the required agencies and as soon as possible file the written report.
• The Wastewater Utilities Supervisor is in the field providing direction to
the field crews and will continuously inform the Utilities Manager and/or
Director to insure the correct actions are taken.
(e) Procedures to address emergency operations, such as traffic and
crowd control and other necessary emergency activities; and
The Water and Wastewater field crews respond to all emergencies, and if
needed, any other City department like the Police Department for crowd
and traffic control, Field Maintenance Division for additional signage,
delineators, barricades, or extra equipment, and the Traffic Division of the
Public Works Department who can develop and supervise the
implementation of traffic control plans.
(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,
361Page
20-38
City of Newport Beach
2019 Sewer System Management Plan
including such accelerated or additional monitoring as may be
necessary to determine the nature and impact of the discharge.
The City crews are required to use mats, sandbags, dirt berms or any
other necessary means to block the catch basin inlets to the storm drains
and use the vacuum trucks or a trailer -mounted vacuum unit to vacuum up
spills and wash down water.
The City has minimized the impact of sewer spills, by washing the area
down with water, capturing the wash water, and removing the captured
wash water with a vacuum truck. The Orange County Health Care
Agency has requested that only fresh water be used because disinfectants
pose their own problems.
The City relies on the California Department of Public Health (CDPH) for
monitoring water quality and posting beach closures. All spills are
reported immediately to the CDPH office and the Regional Board.
Routine preventive operation and maintenance activities by staff and
contractors include scheduling regular maintenance and cleaning of the
collection system with the known problem areas receiving more frequent
cleaning and maintenance. The preventative Maintenance (PM) program
should have a system of tracking work orders and assessing the success
of the PM program.
The City uses work orders and verbal requests, followed up by a work
order, with which field crews respond with a written response. The work
order is then entered into the database for easy retrieval and reports. All
department staff receives one hour of training a month the topics
incorporate safety, program and project updates, and/or new policy
mandates. All staff members are urged to discuss ideas to improve
programs or daily work tasks.
371Page
20-39
City of Newport Beach
2019 Sewer System Management Plan
The City cleans approximately 30,000 feet of high maintenance areas on
monthly runs and approximately 20,000 feet on the quarterly runs. In
addition, the City cleans all of its wet wells quarterly to complete the
cleaning of the City's sewer infrastructure.
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;
The City has already adopted a grease control ordinance and a restaurant
inspection program and finds it does have the authority to adopt and
implement certain grease control regulations on public and private
property. Utilities Department worked in conjunction with the three
agencies inside the city's boundary that have building departments - the
City of Costa Mesa, the City of Newport Beach, and the Orange County
Sanitation District- to adopt common grease control regulations.
Inspection and enforcement activities are recognized as key components
to a successful program. See section Illd for more information.
(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;
The City disposes of all of its wastewater solids waste including FOG at
the Orange County Sanitation District.
W
20-40
City of Newport Beach
2019 Sewer System Management Plan
(c) The legal authority to prohibit discharges to the system and identify
measures to prevent SSOs and blockages caused by FOG;
The City's Municipal Code, Chapter 14, Section 30 gives the City the
authority to prohibit discharges to the City's sewer system.
(d) Requirements to install grease removal devices (such as
interceptors), design standards for removal devices, maintenance
requirements, BMP requirements, record keeping and reporting
requirements;
The City's Municipal Code Chapter 14, gives the authority to require the
installation of grease removal devices, per the Plumbing Code, which is
enforced by the City's Plan Checkers and Inspectors. Utilities Department
has the ability to implement design standards and the City has a contract
inspector who inspects all FSE's on a regular basis for maintenance and
BMP requirements and provides the City with a spreadsheet of his
findings. See section Illd for more information.
(e) Authority to inspect grease producing facilities, enforcement
authorities, and whether the Enrollee has sufficient staff to inspect
and enforce the FOG Ordinance;
The City's Municipal Code Chapter 14 gives City staff the authority to
inspect grease -producing facilities. Working with our Code Enforcement
staff the City has the enforcement authority to write Notices of Violation
and citations (14.04.130 — Enforcement of Violations). See Section Illd for
more information.
(f) An identification of sanitary sewer system sections subject to FOG
blockages and establishment of a cleaning maintenance schedule for
each section; and
The City has a list of high maintenance areas that it cleans and monitors
on a monthly basis, in addition to the regular cleaning schedules utilized
by staff.
391Page
20-41
City of Newport Beach
2019 Sewer System Management Plan
(g) Development and implementation of source control measures for all
sources of FOG discharges to the sanitary sewer system for each
section identified in (f) above.
Staff works with contracted City's FSE Inspector to reduce the grease
levels within FSE's through the use of BMPs. Staff also uses CCTV to look
at the source of these problems to make the necessary repairs to
eliminate FOG discharge locations from the list. This is an on-going
process that personnel works diligently on so that areas of high
maintenance can be moved to regular cleaning schedules or be removed
all together.
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 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.
The City has completed its Sewer Master Plan, which incorporates a
hydraulic analysis of every line in the system and plans for increasing
capacity for those lines found unable to handle future master planned
flows. The current system capacity is able to handle, without problem, the
current dry weather and wet weather peak sewer flows. The Sewer Master
Plan was prepared and reviewed by AKM Consulting Engineers in 2010.

City of Newport Beach
2019 Sewer System Management Plan
As documented by the City's Water Master Plan and water production
records, water use and sewer use has been on a 20 -year downward trend.
The Sewer Master Plan contains a list of each project identified as
necessary to increase the capacity of portions of the system. No
improvements are required in the short term and long-term improvements
will be planned according to development and metered sewer flows.
During the design of each project, alternative designs are considered.
(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
The City Engineer utilizes professional judgement and industry standard
design criteria when evaluating development projects and the City's
Capital Improvement Projects. The City's Standard Plan and
Specifications are also used.
(c) Capacity Enhancement Measures: The steps needed to establish a
short-term and long-term CIP to address identified hydraulic
deficiencies including prioritization, alternatives analysis, and
schedules. The CIP may include increases in pipe size, 1/1 reduction
programs, increases in redundancy in pumping capacity, and
storage facilities. The CIP shall include an implementation schedule
and shall identify sources of funding.
The City has a Sewer Master Plan, and the 5 -year Capital Improvement
Program to adequately address the sewer system needs. With the 2017
Sewer Rate Study, there is sufficient dedicated Capital funding for the
specified projects.
(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.

The City's Sewer Master Plan includes a schedule for CIP, and is tracked
by the Public Works Department as part of the Sewer Master Plan.
IX Monitoring, Measurement and Program Modifications.
(a) Maintain relevant information that can be used to establish and
prioritize appropriate SSMP activities;
Staff maintains cleaning logs and CCTV documentation for the system.
Areas that need prioritizing into a future CIP, point repair or regular
cleaning or service change are programed into the Capital Improvement
Program. The City maintains over the required five years for all
documentation including CCTV.
(b) Monitor the implementation and, where appropriate, measure the
effectiveness of each element of the SSMP;
The SSMP will be reviewed on a regular basis to insure all the provisions
are implemented and the effectiveness discussed at the quarterly and
monthly safety and training meetings as needed. All monthly staff
meetings include field crews, administrative staff, and management staff.
(c) Assess the success of the preventative maintenance program;
The success of the preventative maintenance program is regularly
reviewed by the reduction in spills and the elimination of high maintenance
areas. Staff members continually look for ways to improve the efficiency of
maintaining the City's sewer system.
(d) Update program elements, as appropriate, based on monitoring or
performance evaluations; and
The SSMP and its elements will be updated in accordance with the results
of monitoring and staff recommendations. For instance, if the study of
enzymes and bacteria progresses and the effectiveness determined
successful enough to be used with BMP's and in -lieu of or in -conjunction
with a grease control device for grease mitigation and control. The Sewer

System Management Plan and City policies will be revised as needed to
facilitate the results of the study and the needs of the City's infrastructure.
Performance evaluations are on-going because the daily operations of the
City includes all the elements of the program.
(e) Identify and illustrate SSO trends, including frequency, location, and
volume.
The Utilities Supervisor keeps a report of all spills and maintains tracking
information to see the trends of spills based on location and type of spill.
The report includes 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 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.
The City performs the required internal audits evaluating its SSMP and its
compliance with the WDR as required. Staff update this SSMP document
Regularly and bring the significant changes back for Council approval as required
or needed. The City has completed audits starting in 2011 and has continued
annually especially to note changes to any procedures or operations. These
have been incorporated into this current SSMP.
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 City has developed the following Communications Program to ensure the
public is aware on the development, implementation and performance of the
20-45

SSMP. The Program provides the public the opportunity to comment on the
SSMP and the implementation of the Plan.
• Utilities Department participates in City Newsletters and the City
Manager's newsletter.
• Utilities Department staff regularly presents information at City
Committee's such as the Water Quality/Coastal Tidelands
Committee. Staff also regularly present information at townhall
meetings, HOA's meetings, Chamber of Commerce meetings and
City and Community events and parades.
• This SSMP will be presented to the City Council during one of their
standard regular meetings and is made available to the public.
• The SSMP document is available on City's website for the public to
review and comment.
• Sewer overflow performance information is available to the public
on the State Water Resources Control Board (SWRCB) California
