WDR Waste Discharge Requirements
INTRODUCTION
On May 2, 2006, the State Water Resources Control Board adopted Statewide General
Waste Discharge Requirements for Sewer Systems. The intent of the Order is to
regulate all collections systems in the State in an effort to reduce or eliminate the
number of Sewer Overflows (SSOs) which, by their nature, pollute the environment.
The Order is applicable for all publicly owned sewage collection systems with more than
one mile of sewer pipe. The City of Carlsbad has more than 1 mile of sewer pipe and
therefore, is subject to this Order.
8
In response to the 2006 WDR Order, the City of Carlsbad submitted an application for
permit coverage with the State Water Resources Control Board and was issued Agency
WDID # 9SSO11209. The City of Carlsbad is required to comply with all conditions of the
Order, and is subject to enforcement action for any noncompliance therewith.
Order No. 2006-003-DWQ prohibits any SSO that results in a discharge of untreated or
partially treated wastewater to waters of the United States or that results in a discharge
of untreated or partially treated wastewater that creates a nuisance as defined in
California Water Code Section 13050(m).
The California Water Code provides vanous enforcement options, including civil
monetary remedies, for violations of Order No. 2006-0003-DWQ.
A sewer overflow (SSO) is any overflow, spill, release, discharge or diversion of
wastewater from a sewer system. SSOs include:
• overflows or releases of wastewater that reach waters of the United States;
• overflows or releases of wastewater that do not reach waters of the United
States; and
• wastewater backups into buildings and on private property that are caused
by blockages or flow conditions in a sewer, other than a building lateral.
Wastewater backups into buildings caused by a blockage or other
malfunction of a building lateral that is privately owned is a SSO when
sewage is discharged off a private property into streets, stormdrains, or
waters of the State.
The Order requires the following:
1. In the event of a SSO, all feasible steps shall be taken to contain and mitigate
the impacts of a SSO. This includes taking steps to prevent untreated or
partially treated wastewater from discharging from storm drains into flood
control channels or waters of the United States by blocking the storm drainage
system and by removing the wastewater from the storm drains.
2. If a SSO does occur, it must be reported to the SWRCB using an online reporting
system developed by the SWRCB and within the timelines prescribed in the
Order. This reporting system is referred to as CIWQS - the California Integrated
Water Quality System.
3. A Sewer System Management Plan (SSMP) must be developed and address
specific milestones. The milestones in the Order are:
a. SSMP Development Plan and Schedule
b. Goals and Organizational Structure
c. Overflow Emergency Response Program
d. Legal Authority
e. Wastewater Program
f. Grease Control Program
g. Design and Performance Provisions
h. System Evaluation and Capacity Assurance Plan
i. Monitoring, Measurement, and Program Modifications
j. SSMP Program Audits
k. Communication Program
I. Final SSMP, incorporating all of the SSMP requirements
4. The SSMP and the City's program to implement the SSMP must be certified by
the City and must be presented to the City Council for approval at a public
meeting. The City also is required to certify that the milestones have been
completed within the time frames identified in the Order.
In order to complete the certification, the City's authorized representative must
complete the certification portion in the Online SSO Database Questionnaire by
checking the appropriate milestone box and submitting the form electronically
to the State Water Resources Control Board. This is the California Integrated
Water Quality System (CIWQS) survey that is updated annually.
The two year City of Carlsbad internal audit was conducted on July 11, 2011, by
a representative of the Construction Management & Inspection Department,
acting as a third party to insure that the system was not flawed or swayed by an
internal source from the Wastewater Team.
The SSMP must be updated every five (5) years and must include significant
program changes, if any. Re-certification by the City Council is required when
significant updates to the SSMP are made. To complete the re-certification
process, the City must enter the data in the Online SSO Database and mail the
form to the State Water Resources Control Board.
SSMP DEVELOPMENT PLAN AND SCHEDULE
The City of Carlsbad's Development Plan and Schedule addresses those mandatory
SSMP provisions outlined in the Order. These milestones for the City of Carlsbad were
completed as listed below and certified by the LRO on the dates indicated in
parentheses:

GOALS
The City of Carlsbad's Goals addresses those mandatory SSMP provisions outlined in
Section D, 13 (i) Goals and (ii) Organization of SWRCB Order No. 2006-0003.
The goal of this SSMP is to provide a plan and schedule to property manage, operate,
and maintain all parts of the City of Cartsbad's sewer system. The SSMP must also
prevent and minimize sewer overflows and mitigate SSOs that do occur. Specific goals
are as follows:
• To clean all gravity mains (12" and smaller) within the City's wastewater
collection system on a three year rotation.
• To clean all gravity mains (larger than 12") every 5 years.
• To perform routine sewer lift station checks 3 days/week for larger stations
(>50,000 gallons) and 2 days/week for smaller stations (<50,000 gallons), and
preventive maintenance according to manufacturer's standards.
• To perform routine closed circuit televising inspections of the gravity sewer
system.
• To respond to service requests in an orderty and timely fashion.
• To perform sewer mark outs as received by Dig-Alert within 2 business days for
routine markouts and immediately for emergency markouts.
• To maintain easements to assure access for maintenance activities.
• To maintain an ongoing inventory of routine maintenance parts and critical
parts.

ORGANIZATION
The organization structure identifies the name of the responsible or authorized
representative of the City, as described in Section J of SWRCB Order No. 2006-0003. It
identifies the administrative and maintenance positions responsible for implementing
specific measures in the SSMP with up-to-date descnptions, responsibilities of
personnel, and authority for each position. The organization structure includes a chain
of communication for reporting SSOs and lines of authority with contact information.
The City of Carlsbad's Organizational Structure encompasses the following components:
(1) The name of the responsible or authonzed representative as described in Section
J of SWRCB Order No. 2006-0003.
(2) 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 narrative explanation; and
(3) The chain of communication for reporting SSOs, from receipt of a complaint or
other information, including the person responsible for reporting SSOs to the
State and Regional Water Board and other agencies if applicable (such as County
Health Officer, County Environmental Health Agency, Regional Water Board,
and/or the State Office of Emergency Services).
COMPLIANCE SUMMARY
As shown in the Appendix, the City of Carlsbad maintains an organizational chart which
illustrates the lines of authority and employee titles. Additionally, the City of Cartsbad
provides sufficient staffing information to properly manage, operate, and maintain all
parts of the city's sewer system. The City of Carlsbad Overflow Emergency Response
Plan descnbes the chain of communication for reporting and responding to SSOs.
In summary, the City of Cartsbad's Utilities Wastewater Division maintains an
Organizational Structure which meets the requirements of Section D (ii) Organization of
SWRCB Order No. 2006-0003.

During an emergency incident such as a major spill, force main rupture or pump station
failure, the National Incident Management System structure will be instituted
compnsing the five major functional areas of command, operations, planning, logistics,
and finance/administration as outlines in the Spill Response Plan.
California Water Resources Control Board (RWQB), Region 9 requires notification of all
sewer overflows (SSOs) regardless of quantity or ownership. All SSOs must be reported
through the California Integrated Water Quality System (CIWQS) online database. Spills
are categorized into two areas: Category 1 and Category 2 spill types.
Categorv 1 Spills
A Category 1 spill is any spill:
• that results in a discharge to a drainage channel
• that discharges to surface water or discharges to a storm drainpipe that
was not fully captured and returned to the sewer system.
• of 1000 gallons or more.
Spills that result in a discharge to a drainage channel and/or surface water require
notification as soon as possible, but not later than two (2) hours after becoming aware
of the discharge. Notifications shall be made to:
• The California Emergency Management Agency (Cal EMA, was OES) (1-
800-852-7550 and through the CIWQS); and
• The local Health Officer or Directors of Environmental Health with
junsdiction over affected water bodies - San Diego County Environmental
Health
14
(Ewan Moffitt, 1-619-338-2386, cell 1-619-253-4983 and through the
CIWQS); and
• The Regional Water Quality Control Board (Eric Becker, 1-858-467-2952
and Mark Alpert, 858-336-2313 or through the CIWQS)
A draft report through the California Integrated Water Quality System (CIWQS) online is
required as soon as possible but no later than twenty-four (24) hours after becoming
aware of the discharge to a drainage channel or surface water, and a copy faxed to
County of San Diego Environmental Health. If the online system is not available, the
report can be e-mailed to: rb9sso@waterboards.ca.gov or sent by fax to 858-571-6972.
Spills of 1000 gallons or more must be reported as soon as the City has knowledge of the
discharge, reporting is possible and reporting can be provided without substantially
impeding cleanup or other emergency measures.
Categorv 2 Spills
Category 2 spills include all other discharges of sewage resulting from a failure in the
City of Carlsbad's sewer system.
Category 2 spills must be reported through CIWQS within 30 days after the end of the
calendar month in which the SSO occurs. Full documentation of all responses shall be
maintained for a minimum of one year. Any month without spills will be certified as a
no spill month.
Any SSO that affects any surface water requires an immediate call to the California
Department of Health Services. This notification is done through The California
Emergency Management Agency (Cal EMA, was OES).
Private Lateral Spills
All private lateral sewage discharges will be reported through the CIWQS database. The
online report must identify the sewage discharge as occurnng and caused by a pnvate
lateral. The responsible private party should also be identified, if known.

6. Development and implementation of source control measures for all sources
of FOG discharged to the system for each section identified.
7. Implementation of a plan and schedule for a public education outreach
program that promotes proper disposal of FOG.
COMPLIANCE SUMMARY
To reduce the amount of Fats, Oils and Grease discharged to the Cit/s sewer system,
the City has developed a FOG Control Program. The City identifies all food preparation
and service locations within its service area. Facilities are provided with a FOG binder
consisting of an educational video, posters and other materials educating them on
proper FOG disposal. These customers must undergo annual GBMP inspection (Grease
Best Management Practices) by the City's contractor responsible for inspections where
the following is evaluated: exhaust hoods, documentation, existing FOG fixtures, and
review of best management practices in the food preparation area. A second
inspection, called a Grease Control Device Inspection (GCDI) is also performed annually
by the City's contractor to ensure that interceptors are routinely serviced to minimize
FOG discharges to the sewer system. Food preparation and service locations must keep
annual records of maintenance of grease control device(s). Customers with a history of
24
contributing FOG to the sewer system are sent a letter of correction. The City maintains
an active listing of all food preparation and service locations and permits are not
required at this time.
All interceptors and other grease control devices are inspected annually with more
frequent inspections of those facilities experiencing inconsistent maintenance practices.
The City maintains standard drawings for grease interceptors and there are several
independent vendors which will collect and dispose of accumulated FOG.
The City has identified the sections of the sewer system subject to higher levels of FOG
and has developed a quarterly cleaning program for those sections. As sewer lines are
cleaned, the severity of the FOG accumulation is documented in the Hansen work
management system and the quarterly cleaning program is updated on an annual basis
based on the most recent data collected by field staff. In summary, the City maintains a
FOG Control program which meets the requirements of Section D, 13(vii) FOG Control
Program of SWRCB Order No. 2006-0003.
(1) The City maintains a plan and schedule for the disposal of FOG generated
within their service area in the City's Source Control Program; Food
Service Establishment Grease Best Management Inspections and the
Source Control Program: Food Service Establishment Grease Control
Device Inspections Log. The City distributes a FOG BMP binder to all
affected facilities. The binder provides a list of independent vendors
which can provide collection and disposal services in the service area.
(2) The City possesses the legal authority to prohibit discharges to the
system and identify measures to prevent SSOs and blockages caused by
FOG through the City of Carlsbad. Municipgl Code. Chapter 13 (Sewers).

records of the staff that cleaned the line, the equipment used, the size and length of the
pipe, the amount of debris gathered, the manhole condition assessments on the line,
and any relevant remarks observed during the cleaning. The City uses the Hansen work
order management system for preventive maintenance work orders.
In the fall of 2008, the City began a system-wide video inspection of the sewer mains
sized 12" and under. The video inspection work is scheduled to be completed system-
wide every four years. Additionally, City staff observes all gravity mains during routine
cleaning and conduct localized video inspections when their observations in the field
warrant further investigation. The City maintains a log of this continued video
inspection in its Video Inspection Loa. During the localized video inspection and the
manhole inspection, each asset is given a ranking based on the observed overall
condition and defect (if any). These rankings, as well as the observed condition of each
pipeline, allow the City to identify gravity mains that are at risk of collapse or prone to
more frequent blockages due to pipe defects.
In order to monitor the implementation and measure the effectiveness of the SSMP,
Carlsbad Wastewater Division tracks several performance indicators, including:
Reactionary Efforts
• Location of all overflows;
• Amount of overflow recaptured and/or released to the environment;
• Cause of the overflows as revealed through CCTV investigation;
• Average response time of staff to arrive at an overflow location;
It is anticipated that performance measures will be compared over time and an effort
made towards lowering or eliminating each adverse result.
Proactive Efforts
• Volume of sewage spills per mile of sewer mains;
• Station Facility Maintenance: Percentage of planned work activities completed
during the fiscal year based on standards established in the Maintenance
Assessment Program;
• City of Carlsbad Public Opinion Survey on Wastewater Operations (90% of
customers rate sewer services as "good or excellent.");
• Sewer Main Cleaning: Percentage of planned work activities completed during
the fiscal year based on standards established in the Maintenance Assessment
Program;
• Record and track total mileage of gravity sewer system cleaned annually;
30
• Evaluation of the "High Priority" areas to evaluate whether to add or delete
sections ofthe system from the accelerated cleaning schedule;
• Percentage of total gravity sewer system cleaned annually;
• Number of manholes inspected annually;
• Number of Interceptors inspected and/or cleaned annually;
• Percentage of wet wells cleaned annually.
Some of these performance measures are tracked in the City-wide State of Effectiveness
Report, an annual report analyzing Carisbad's performance against established
measures. The Carlsbad Wastewater Division is committed to gathering and evaluating
the data collected on an annual basis and more frequently if the situation arises. Staff
will evaluate each section of the SSMP and will recommend changes if warranted.
In conclusion, Carisbad Wastewater Division maintains a Monitoring, Measurement, and
Program Modifications which meet the requirements of Section D, 13, Monitoring,
Measurement and Program Modifications in SWRCB Order No. 2006-003.
(1) The City tracks the location and cause of all SSOs, blockages, and gravity main
hot-spots. The City maintains a log of all cleaning activity by zone, which details
the size, material and location of each pipe cleaned. The City maintains a
Computerized Maintenance Management System, which utilizes Hansen
software for preventative maintenance and work orders, as well as a log of
continued video inspection efforts in the Video Inspection Loa. The City
identifies all food preparation and service locations within its service area as part
of the monitoring and surveillance program. A list of all customers is maintained
by the City. All interceptors on the Source Control Program: Food Service Facility
Grease Control Device Inspections Log are inspected at a minimum on once
annually by City staff or a consultant;
(2) The City monitors the implementation of the SSMP, and measures the
effectiveness of each element of the SSMP by developing and tracking
performance indicators on an annual basis;
(3) By tracking performance indicators, the City is able to assess the success of its
preventative maintenance program;
(4) The City has assigned a team from the Wastewater Division to review the SSMP
annually, in order to update all program elements as appropriate. In addition to
tracking the above performance indicators, the staff member will review all
sections of the SSMP for effectiveness and timeliness. Collection system
personnel will also be consulted annually to review the effectiveness of the
SSMP, and help identify potential areas for improvement.
31
(5) The City tracks the frequency, location and volume of all SSOs.

SSMP PROGRAM AUDITS
The City's SSMP Program Audits addresses the mandatory SSMP provision outlined in Section D,
13 (x) SSMP Program Audits of SWRCB Order No. 2006-0003.
As a part of the SSMP, the City of Carlsbad's Wastewater Department is required to
conduct a periodic internal audit, appropriate to the size of the system and number of
SSO's. At a minimum, these audits must occur every two years and a report must be
prepared and kept on file. The audit needs to focus on evaluating the effectiveness of
the SSMP and the City of Carlsbad's compliance with the SSMP requirements of
subsection (D.13), including identification of any deficiencies and the steps to correct
them. City of Cartsbad conducted the two-year audit and certified the revised SSMP on
July 11, 2011.
COMPLIANCE SUMMARY
The City of Carlsbad has a current internal audit program that has been expanded to
cover the WDR program and its elements. An internal audit covering both compliance
and conformance was conducted prior to the submittal of the final SSMP to ensure that
it meets all requirements ofthe Order.
The City of Carlsbad's Utilities Wastewater Department management team will assign
the appropriate staff to conduct department wide audits as the WDR is implemented
and utilized. Strategies to correct deficiencies, if identified, will be developed by the
responsible division within the department with assistance from Utilities Management.
The City of Carlsbad will meet with other neighboring agencies in the wastewater
industry to discuss collaborative auditing approaches, pending the availability of
resources. Each agency will be at different stages of their SSMP Plan, therefore it will
depend on the agency's progress to determine if they can participate with this effort.
The City of Carlsbad internal audits are to be conducted using the criteria below. A
sister agency such as a neighboring Department of Public Works or Wastewater Agency
will be asked to conduct the audits, acting as a third party to insure that the system is
not flawed or swayed by an internal source from the Wastewater Team.
31
32
Deficiencies identified as a result of the audit will be brought to the attention of each
responsible City of Carlsbad Division. Deficiencies and corrective actions will be
identified, verified, and documented by the Wastewater Management Team.
The audit will include, but not limited to, the following;
• Any significant changes to the components of the SSMP, including but not
limited to. Legal Authority, FOG Control Program or Sewer Overflow Response
Plan,
• SSMP implementation efforts over the past years,
• A description of additions and improvements made to the sewer collections
system over the past two years,
• A description of additions and improvements planned for the upcoming two
years, with estimated schedule for implementation, and
• Strategies to correct deficiencies, if identified, will be developed by the
responsible City of Carlsbad staff.
COMMUNICATION PROGRAM
The City of Carlsbad's Communication Program addresses the mandatory SSMP
provision outlined in Section D, 13 (xi) Communication Program of SWRCB Order No.
2003-0003. The provision requires the City of Carlsbad to communicate regularly with
and allow input from interested parties on the development, implementation, and
performance of its SSMP.
