CITY OF SAN LUIS O B I S P O
FROM: Carrie Mattingly, Utilities Director
Prepared By: Jennifer Metz,Utilities Projects Manager
SUBJECT: SEWER SYSTEM MANAGEMENT PLAN
RECOMMENDATION
Adopt a resolution approving the Sewer System Management Plan (SSMP) and authorize the
Utilities Director, as the City's authorized representative, to file a Notice of Completion with the
State Water Resources Control Board(SWRCB).
DISCUSSION
Background
On May 2, 2006, the SWRCB adopted Statewide General Waste Discharge Requirements
(GWDR) for publicly owned sanitary sewer systems. The GWDR requires the development and
implementation of a system-specific local SSMP that documents a comprehensive program for
sewer system operation, maintenance and repair. The regulations also include provisions that the
agency's governing body approve, at a public meeting, the final SSMP by August 2, 2009.
The regulations require a public agency that owns or operates a sanitary sewer system to develop
and implement a sewer system management plan and report all Sanitary Sewer Overflows
(SSOs) to the State Water Board's online SSO database. SSOs have been identified as a major
threat to public health and water quality because of the pathogens, toxic pollutants and nutrients
they contain and have been a focus of State Water Quality Regulators over the past several years.
Public agencies that own or operate a sanitary sewer system that is comprised of one mile or
more of pipeline which transports sewage to a treatment facility must file a Notice of Intent
(NOI) to comply with the requirements. The program has two major components including
reporting all SSOs in the statewide spill reporting database and development of the SSMP. On
July 13, 2006 the City submitted its NOI and began using the statewide spill-reporting database
on May 2, 2007. In October 2007, the City Council approved the development plan and schedule
for the preparation of the SSMP. The preparation, Council adoption and implementation of the
City's SSMP fulfills the remaining requirement of the State Order.
Plan Highlights
The SSMP compiles the City's existing and planned programs to provide proper and efficient
management, operation, and maintenance of its sanitary sewer system, including a spill response
plan to ensure a standard and effective response to SSOs. The Plan has eleven sections,
described below.

1. Goals. The City's SSMP includes ten goals in order to reduce and prevent
sanitary sewer overflows and mitigate any overflows that may occur.
2. Organization. This section identifies the responsible City representatives for
implementing specific measures in the SSMP including the chain of
communication for reporting sanitary sewer overflows.
3. Legal Authority. This section describes the authority the City has to implement
the provisions of the SSMP from the Municipal Code. It also describes the City's
agreements to provide wastewater collection services to satellite agencies (Cal
Poly and the San Luis Obispo County Airport).
4. Operation and Maintenance. This section summarizes the City's preventive and
area in programs, CCTV inspections, lift station maintenance, the
computerized maintenance management system, collection system mapping, on-
going training required for the Wastewater Collection staff to comply with State
Regulations in order to minimize and prevent sanitary sewer overflows and
maintenance equipment and replacement part inventories.
5. Design and Performance Provisions. This section describes the City's standards
for installation, rehabilitation and repair of the collection system and inspection
and testing requirements for new and rehabilitated facilities.
6. Overflow Emergency Response Plan. This section details the history of
stoppages and overflow events in the City and how Wastewater Collection staff
responds to overflow emergencies.
7. Fats, Oils and Grease Control Program. This section describes the City's FOG
program including requirements for grease removal devices and efforts to educate
facilities on the disposal of fats, oils and grease.
8. System Evaluation and Capacity Assurance. This section summarizes past and
planned efforts related to capacity assessment and enhancement, identifies future
wastewater collection system capital projects and describes the City's voluntary
service lateral program.
9. Monitoring, Measurement and Program Modifications. This section describes
how the City will monitor and measure its performance through the
implementation of the Plan and make necessary modifications to improve the
management of the City's collection system in the future. Indicators are identified
that will be use to measure the performance of its wastewater collections system
and the effectiveness of its SSMP.
10. Program Audits. This section outlines the process that the City will follow to
evaluate the effectiveness of the SSMP to identify updates that may be needed for
83�v�

a more effective program. Audits are proposed to be conducted on an annual
basis.
I.I. Communication Program. This section describes how the City will
communicate with the public and satellite agencies on the performance of the
SSMP. Examples of past communication from the Utilities Department's
Resource publication are provided.
As described in the SSMP, the plan will undergo an internal audit by staff each year, and will
require recertification and approval by Council every five years. Staff proposes to bring an
updated SSMP back to Council for approval in April 2014.
Updated Notification Protocol
After the City's March I" sewage_spill staff received several concerns from residents who were
not adequately notified of the health risks and impacts to their property. County Environmental
Health has been the agency that is responsible for the notification of sewage spills, but after the
spill it became apparent that a change to the notification process was warranted. To address this,
City and County staff, working together, have developed a more comprehensive and proactive
notification process. This process will allow City staff to post warning signs along the creek and
door tag effected residences. City staff walking neighborhoods, posting, door tagging and
speaking to residents will provide a significantly improved and more effective level of
notification to residents. The City will also utilize its GIS mapping system to ensure staff
properly covers the area. This will eventually become a county-wide protocol for citizen
notification of sewage spills.
Summary
Development of this SSMP was performed by City staff to ensure an accurate, comprehensive
document that not only meets State regulations, but serves as a useful guide that will
complement existing procedures and policies for the ongoing maintenance and operation of the
City's wastewater collection system. With the support of Council, many required activities and
program elements for this regulation are currently being performed by the Wastewater Collection
and Industrial Waste sections.
FISCAL IMPACT
There is no fiscal impact related to the adoption of the SSMP. Funding for the programs and
projects documented in the SSMP will be included in the 2009-11 Financial Plan for Council's
consideration.
