Council Meeting: July 8,2003 Santa Monica, California
JUl - 8 2003
TO: Mayor and City Council
FROM: City Staff
SUBJECT: Memorandums of Understanding to Develop Implementation and
Monitoring Plans to Comply with the Los Angeles Regional Water Quality
Control Board's Bacterial Total Maximum Daily Load Requirements
Introduction
The report recommends that the City Council authorize the City Manager to negotiate
and execute Memorandums of Understanding with neighboring municipalities within the
sub-watersheds of the Santa Monica Bay-Ballona Creek Watershed to develop
implementation and monitoring plans to comply with the Los Angeles Regional Water
Quality Control Board's Bacterial Total Maximum Daily Load requirements.
BackQround
The Federal Clean Water Act (CWA) requires the California Regional Water Quality
Control Board, Los Angeles Region (Board), to develop water quality standards that
identify beneficial uses and criteria to protect beneficial uses for each water body found
within its region. Beneficial uses include swimming, fishing, drinking water, navigability,
and wildlife habitats and reproduction The Board carries out its CWA responsibilities
through the state's Porter-Cologne Water Quality Control Act and establishes water
quality objectives designed to protect beneficial uses contained in the Water Quality
Control Plan (Basin Plan). Section 303(d) of the CWA requires states to prepare a list
of water bodies that do not meet water quality standards and establish for each of these

water bodies load and waste load allocations (load refers to pollutants), that is, a total
maximum daily load (TMDL) which will ensure attainment of water quality standards,
and then to incorporate those allocations into their Water Quality Basin Plans. A TMDL
represents an amount of pollution that can be released by anthropogenic and natural
sources of a watershed into a specific water body without causing a decline in water
quality and beneficial uses. The TMDL can be a narrative or numerical standard to
control pollution For example, the existing trash TMDL states that no trash can enter
the Bay. For the new bacterial TMDL, a specific number of days of exceeding the
concentration of a bacterium is allowed
Many of the beaches along the Santa Monica Bay (Bay) were listed on California's 1998
Section 303(d) list, due to impairments for coliform or for beach closures associated
with bacteria, as well as many other pollutants. These beaches have been and
continue to be subject to beach closures due to elevated bacterial concentrations,
preventing full enjoyment of the beaches' beneficial use for water contact recreation.
Attachment A lists the beaches within Santa Monica
Discussion
The bacterial TMDL addresses documented bacteriological water quality impairments at
44 beaches within the Bay Watershed from the Los Angeles-Ventura County line to
Outer Cabrillo Beach to the south. Local and national epidemiological studies
demonstrate a causal relationship between adverse health effects, such as
gastroenteritis and upper respiratory illness, and recreational water quality. The water

which will have a primary jurisdiction of the City of Los Angeles, or a combination of
both cities.
J2-3 will use an integrated water resources approach that takes a holistic view of
regional water resources management by integrating planning for future wastewater,
stormwater, recycled water and potable water needs and systems; focusing on
beneficial reuse of stormwater, including groundwater infiltration, at multiple points
throughout a watershed (and sub-watershed); and addressing multiple pollutants for
which the Bay Watershed is listed as impaired on the CWA Section 303(d) list.
approach follows the principles of the City's Sustainable City Plan. These other
pollutants include heavy metals, organic chemicals, hydrocarbons and nutrients
(nitrogen and phosphorous).
The TMDL requires "responsible jurisdictions and agencies" (RJAs) to submit a draft
Implementation Plan (draft plan), within 20 months after the effective date of the TMDL
and a final Implementation Plan (final plan), 24 months after the effective date.
plan's purpose is to outline how each jurisdiction intends to achieve TMDL compliance.
The TMDL also requires the RJAs to submit a monitoring plan for the E3ntire Watershed
within 120 days after the effective date.
The Urban Runoff Management Coordinator represents the City at re~lular meetings
with RJAs to develop the draft plan and monitoring plan. Two separate tracks of
meetings have occurred: meetings for the draft plan including only members of J2-3,
4
and meetings for the monitoring plan including members of all seven jurisdictions.
Approval of the final TMDL by the US EPA came in June 2003, initiating the timeline
that triggers various deadlines.
To comply with the TMDL, the agencies of J2-3 have proposed that a consultant,
currently being used by the City of Los Angeles for similar work, be used to perform the
work to develop the draft plan for the J2-3 members. City of Santa Monica staff concur
with the decision to use the existing consultant because of the consultant's expertise
concerning water quality issues and demonstrated ability to perform the necessary
tasks to fulfill the TMDL's multiple requirements. The City is not responsible for any
monitoring of the storm drain outfalls along its coastline. The City of Los Angeles and
State Department of Health Services perform this work. The new monitoring plan
requires an additional testing site at each outfall, which is an additional expense to the
J2-3 and its members. To pursue this course of action, the City must f:mter into MOUs
with the RJAs to allow this work to be performed in an expeditious manner to meet the
deadlines.
The MOUs will require the City to contribute monies to J2-3 for the draft and final plans,
and to the monitoring plan. A separate staff report will be required to authorize the City
Manager to implement the solutions of the implementation plan.

Budqet/Financiallmpact
At this time, the City's exact share of the costs to implement the N10Us is unknown.
However, the amount will most likely be between $150,000-$250,000. The cost-share
per members of each jurisdiction is presently based on drainage area. Costs include
the development of the final plan to curb bacterial pollution and the monitoring plan
The cost to implement the final plan and the weekly monitoring costs cannot be
estimated at this time. The City is obligated to comply with the TMDL and will have to
take the necessary steps to ensure compliance. The City has already obtained a
number of grants to help meet this compliance. Through the Urban Runoff
Management Plan, presently being developed by a consultant, strategies to raise
additional stormwater funds will be explored.
Funds to cover the anticipated costs up to $250,000 are available in a number of CIP
Stormwater System Improvement accounts (C34058801-04.589000) and the
Environmental Programs Division Operating account, 31662.555060.
Recommendation
Staff recommends that the City Council authorize the City Manager to negotiate and
execute Memorandums of Understanding with neighboring municipalities within the sub-
watersheds of the Santa Monica Bay-Ballona Creek Watershed to develop
implementation and monitoring plans that comply with the requirements of the Los
Angeles Regional Water Quality Control Board's Bacterial Total Maximum Daily Load
requirements.
