TITLE: Adoption of 2014 Sewer System Management Plan
ABSTRACT:
In 2009, Council adopted the City's Sewer System Management Plan, an overview of City procedures and
protocols that minimize Sanitary Sewer Overflows (SSOs). Per the requirements of the State Water
Resources Control Board, the plan is to be updated and presented to Council for re- adoption every five
years.
RECOMMENDATION:
Adopt the City's 2014 Sewer System Management Plan as required by the State Water Resources Control
Board.
FUNDING REQUIREMENTS:
There are no funding requirements required for this action, although the City's investment in its wastewater
collection system is roughly $3 million /year in operational expenses and another $627K planned for capital
in FY 14 -15.
DISCUSSION:
On May 2, 2006, the State Water Resources Control Board (SWRCB) adopted Order Number 2006-0003 -
DWQ. As one of the requirements of the permit, the 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.
The intent of the SSMP is to provide a framework, as well as some specific details, for managing the City's
sewer system to eliminate overflows. The proposed SSMP includes the following elements:
1. Goals
2. Organization
3. Legal Authority
4. Operations & Maintenance
5. Design and Performance Provisions
6. Overflow Emergency Response Plan
7. Grease and Fat Control Plan
8. System Evaluation and Capacity Assurance Plan
203
9. SSMP Program Audits
10. Communications
The SWRCB requires the SSMP be audited every two years following its adoption. Municipal Operations
staff performed an internal audit of the SSMP in October of 2011, and August of 2013. The attached 2014
SSMP is the final version incorporating changes and previous recommendations. Per SWRCB, the 2014
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 ") oversees water quality in
California including the shoreline and Upper and Lower Newport Bay. The 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 have impacted the economy associated with summer beach activity.
In 2006, in response to the beach closures, the State Board adopted General Waste
Discharge Requirements (GWDRs) for the operation of sewage collection systems. The
GWDRs 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 GWDRs 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
August 2010.
The Municipal Operations 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.

(i) Goal. 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 ocean water
quality by preventing sewer spills and is supplementing its existing sewer system
management program with the requirements of the GWDRs.
(ii) Organization. The SSMP must identify:
(a) The name of the responsible or authorized representative as
described in Section J of the Order.
George Murdoch, Utilities General Manager is listed as the City's
authorized representative.
(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
Below is the Organizational Chart showing the lines of authority for all the
field staff and their respective responsibilities for the Wastewater Division
of the Municipal Operations Department. The contact phone number for
Municipal Operations Department, Wastewater Division is (949) 644 -3011,
during working hours; and the Police Department is to be contacted after
hours at (949) 644 -3717. The Police Department will then dispatch an
authorized field staff member.

EMERGENCY RESPONSE PROGRAM RESPONSIBILITIES
Utilities General Manager- Ensure that line- response personnel have all funding
and authority needed to effectively pursue their
obligations under the SSMP. Provide policy guidance
where needed.
Manager Provides feedback to Wastewater Supervisor
regarding operational needs and requirements.
Supports Wastewater Supervisor, and field crews.
Wastewater Supervisor - Directs field crews with the day -to -day operations of
the Wastewater Division and structures emergency
response operations based on experience and
utilization of field staff available.
Field Crews - Implement emergency response plan. 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 Wastewater Supervisor is responsible for overseeing the reporting
process. The Wastewater staff enters 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
General Manager reviews the draft with the Wastewater Supervisor.
6 l P a g c
210
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.
Prior to the State Board's preparation of new reporting requirements, the
City utilized its own reporting form. As a first priority during a sewer spill,
City staff (typically the Wastewater Supervisor) notifies the appropriate
agencies by phone of a SSO instead of depending on the report as a
means of notification.
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 1 /I, stormwater, chemical dumping, unauthorized debris
and cut roots, etc.);
The City Attorney has examined City codes to ensure that 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 the City's sewer system.
By ordinance, the City has established a long -range financial plan to
ensure capital replacement. (City Municipal Code 14.33.040)
The current Title 14 of the Municipal Code regulates sewer construction.
All sewer construction must be in accordance with City standards (Section
7 l P a g c
211
14.24).The inspection requirements by City staff are provided in Chapter
14.04.120.
The City continues to its video inspect all sewer mains in the system. The
results of the video inspection will show sources of infiltration into the
lines, if there are any
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.
(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
8 1 P a g e
212
incorporate the Standard Plans and Specifications for Public Works
Construction (the "Green Book "), which helps insure proper design and
construction of sewer facilities.
(c) Ensure access for maintenance, inspection, or repairs for portions of
the lateral owned or maintained by the Public Agency;
The City employs two full time Public Works Inspectors, each with
numerous years of experience working for the City, as well as one
contracted inspector. All of the City's inspectors are trained and
experienced in pipeline and pumping 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 Provisions and Standard Drawings for
Public Works Construction, the Standard Specifications for Public Works
Construction Inspection Manual, the Work Area Traffic Control Manual
(WATCH), and the CALTRANS Manual for Work Upon Highways, on the
job at all times.
The City utilizes in -house and contract services to CCTV the sewer lines
to monitor the high maintenance areas annually, recent repairs, and also
to fulfill the goal of CCTVing the entire City every 10 years. Continuous
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.
Besides the use of video inspection, the City has adopted a goal to root
cut every linear foot of sewer pipe within the City boundaries every 18
months (with the exception of new areas that contain PVC or lining- these
areas are cleaned with high velocity cleaning trucks.) The more vigilant
the City is in taking a proactive stance to maintain its infrastructure, the
more apt staff is to find problems or areas of concern that need attention.
9 1 P a g c
213
(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 that
will better help 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 legal authority for plumbing fixtures inside a building rests with the
City's Community Development Department and County Health Care
Authority. 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 supports pretreatment as a means of improving the efficiency of
the sewer collection system and treatment plant operation. Because
Orange County Sanitation District has a comprehensive pretreatment
program, the City supports the program and reminds all applicants they
must comply with the recommendations of the OCSD program to receive a
sewer permit from the City. The contractor of FOGs program gives Best
Management Practices guide to all restaurants, which includes information
on how to prevent the discharge of FOGs into the sewer system.

The City Attorney has comprehensively reviewed aspects of the City's
regulatory authority and ensures that the City of Newport Beach's
municipal code meets the requirements of the WDR. Newport Beach
Municipal Code Chapter 14 includes the Right of Inspection and
Enforcement and report of violations.
(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 storm water conveyance facilities.
The City has a Sewer Atlas that is continuously updated as new facilities
are constructed and pipelines are replaced. The Atlas shows the location
of all sewer mains, manholes, laterals, pumping stations and pressurized
sewer lines (force mains). The Atlas also has reference numbers to the
particular construction plans that were used to build each portion of the
system. In addition to the Sewer Atlas, plans of the sewer system are
included in the Sewer Master Plan. The maps in the Master Plan are also
updated as new facilities are constructed and are used in conjunction with
the sewer line capacity calculations as a planning tool for the yearly
Capital Improvement Program.
The City also continuously updates all sewer and storm drain
infrastructure on the City's G.I.S. mapping system, which is maintained by
Municipal Operation and MIS staff.
The locations of all the storm water conveyance facilities are shown on
separate plans; copies of these plans in reduced size format are on file
with the Wastewater Supervisor, Public Works Department and most of
the crew vehicles, where applicable. The City recognizes the link between
11IPaLrC
215
a SSO and its path of travel in a storm drain facility 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 new 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 many 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 in Newport Beach to the Storm Drain Division.
(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. Presently, Newport Beach is on an eighteen -
month program of sewer cleaning. Areas needing more frequent cleaning
– known as "high maintenance areas" – are cleaned as frequently as
monthly and quarterly. These include inverted siphons that run under
flood control channels and bay crossings or commercial areas with
multiple restaurants.
12IPa-L c
216
The City has one hydro truck and two combination hydro- vacuum trucks
specifically for spill cleanup, each with a two - person crew. The City sends
out two crews daily, sometimes three -- staff permitting. Again, the City
has areas of monthly and quarterly cleaning, this proactive approach helps
the City stay abreast of all areas of the City, especially the high
maintenance areas.
In addition to the daily cleaning of the gravity sewer lines by crews, the
Wastewater Crews maintain 21 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). ESSCO
operates as a primary contact for the City during emergencies. ESSCO
have provided this service to the City for the past 40 years as it relates to
the equipment at the City's sewer facilities.
The City also has two additional Wastewater crews that help maintain the
City's sewer infrastructure. These include:
two person repair crew that primarily installs, repairs or replaces sewer
laterals and cleanouts (the City of Newport Beach owns and maintains
all sewer laterals); and
two person pump crew that maintains the pumps and motors for all 21
sewer pump stations;
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
13IP; ) c
217
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;
Studies by the City have identified the main causes of SSOs within the
City and efforts have been prioritized to eliminate the causes. The
Municipal Operations Department keeps a running spreadsheet of sewer
spills that includes the causes of the spill. Staff uses the spreadsheet to
plan activities, programs, and policies to eliminate the causes. The City
identified tree roots in conjunction with grease as the primary cause of
spills in the City. Restaurant grease is also a major cause of sewer line
blockages and spills. The City has an ordinance requiring grease control
devices for new restaurants and restaurants undertaking a major remodel.
Frequency and volume studies of sewer spills do not disclose any new
identifiable trends. A trend of either frequency or volume indicates a
chronic problem that can be specifically identified. The City has identified
all the areas prone to problems —high maintenance areas — and services
these on a regular basis.
(d) Provide training on a regular basis for staff in sanitary system
operations and maintenance, and require contractors to be
appropriately trained; and
The City requires all Wastewater personnel to have, at a minimum, Grade
1 certification provided by the California Water Environment Agency
14IPage
218
(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 Grade I Collections or higher.
(e) Provide equipment and replacement part inventories, including
identification of critical replacement parts.
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.
(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
15IPa�)c
219
The City's standards for the proper installation and inspection of sewer
lines are discussed in Section (iii) (b) above. Additionally, the City has
standardized its use of equipment 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 is monitoring the field of "no -dig" pipeline rehabilitation as
advancements are continually being made. The City considers no -dig
technology to be the future answer to pipeline rehabilitation as systems
reach their life expectancy. The City still utilizes the method of pipeline
removal and replacement in conjunction with new pipeline re- lining
technologies as they emerge and are tested.
(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 Green Book Inspection Manual for reference if
needed although their years of experience and training allow them to
provide excellent observation of contractors' work. With regard to testing
sewer lines, the City uses the Green Book recommended air - testing
procedures on all new main lines.
(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:
16
220
(a) Proper notification procedures so that the primary responders and
regulatory agencies are informed of all SSOs in a timely manner;
We have and will continue to inform all residents that, during regular
business hours, Municipal Operations staff can be reached at (949) 644-
3011, or by contacting the Police Department's Dispatcher desk at (949)
644 -3717. After hours, the emergency standby duty personnel can be
reached through dispatch at (949) 644 -3717. Emergency stand -by duty
personnel carry a pager and cell phone for ease of access by the Police
Department after hours.
(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 Municipal Operations Department
staff cross -train between Wastewater and Water Maintenance & Repair,
there are plenty of trained and qualified staff to assist at any time with
SSOs.
(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
17In,i, „,
221
requirements. The SSMP should identify the officials who will receive
immediate notification:
The City's policy has always been 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.
(d) Procedures to ensure that appropriate staff and contractor personnel
are aware of and follow the Emergency Response Plan and are
appropriately trained;
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 Supervisor is in the field, documenting the situation
with pictures and verbal reports back to the administrative staff in the
office. The Wastewater Supervisor will verbally report any sewer spills
to the required agencies and as soon as possible file the written report.
The Wastewater Supervisor is in the field providing direction to the field
crews and will continuously inform the Utilities General Manager and /or
Director to insure the correct actions are taken.
18IPage
222
(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,
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.
19 11,
223
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.
The City cleans approximately 30,000 feet of high maintenance areas on
monthly runs and approximately 20,000 feet on the quarterly runs. Plus
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 finds it does
have the authority to adopt and implement certain grease control
20IPage
224
regulations on public and private property. Municipal Operations
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.
(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 waste at the Orange County Sanitation
District.
(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, Section 30 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. Municipal
Operations has the ability to implement design standards and the City has
a contract inspector who inspects all FSE's on a regular basis for
21IPa�rc
225
maintenance and BMP requirements and provides the City with a
spreadsheet of his findings.
(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).
(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.
(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 has worked with the 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
2211'; ) c
226
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 were reviewed by
AKM Consulting Engineers.
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 will hire a professional engineer if the need arises to develop
additional design criteria outside of what is in the CIP or part of the City's
Standard Specifications.

(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, I/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 just completed its new Sewer Master Plan, which includes CIP
and funding sources. The City is conducting a Wastewater Rate study,
which is set to be completed in 2014.
(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, but staff will
review the documents as required.
(ix) Monitoring, Measurement and Program Modifications. The Enrollee shall:
(a) Maintain relevant information that can be used to establish and
prioritize appropriate SSMP activities;
Staff maintains logs and CCTV documentation of areas that need
prioritizing into a future CIP, point repair or regular cleaning or service
change. 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;
24 I r' r
228
The SSMP will be reviewed on a regular basis to insure all the provisions
are implemented and the effectiveness discussed at the 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 Wastewater Supervisor keeps a report of all spills and maintains a
spreadsheet 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
25 I r'
229
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 will perform the required internal audits evaluating its SSMP and its
compliance with the GWDR as required. The City Council has directed staff to
update this SSMP document continuously and bring the changes back for
Council approval as required or needed. The City completed its first internal
audit in October of 2011, and its second internal audit in August of 2013,
changes to any procedures or operations where incorporated into the 2014
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 will provide interested parties with status updates on the implementation
of the components of the SSMP. The City will also consider comments made by
interested parties. The SSMP and other wastewater information are available on
the City website: http: / /www.newportbeachca.gov.
