NPDES Permit History
Clean Water Act Amendment in 1987
(called the Water Quality Act)
Regulates Discharge of Urban Runoff & Storm Water
Orange County is Lead Permittee with Cities as Co-Permittees
Working on 5th Term Permit (Next Draft Anticipated Late 2015)

Issue : Excessive Nutrients causing Algal Blooms in Creek & Bay
Nutrient TMDL Adopted in 1998
Requirement - Reduce Nitrogen and Phosphorus Loads by 50%
relative to 1990-1997 Loads
Reduce Summer Loads by 50% by 2007
Reduce Winter Loads by 50% by 2012
Treatment Methods Established :
Nursery Irrigation Flow Recirculation and Reuse
Education of Landscape Maintenance and Gardener Services

Organochlorine Compounds TMDL
Issue : Toxicity Associated with Organocholorine Compounds (OCs)
i .e. DDT, PCBs, Toxaphene and Chlordane ( Legacy Pesticides)
OCs TMDL Established in 2007
NPDES Permit Requires Sampling of Bay Sediments for Toxicity
The Good News
Sources of Legacy Pesticides in the Upper Watershed are
Disappearing
OCs Appear to be Declining in the Bay Sediments
NOTE: Pesticide Application Reduced Citywide by 29% from 2012

• TMDL is for Fecal Coliform Only
TMDL Currently Does Not Exclude Natural Sources* of Indicator

Issues/Concerns
Copper-Based Paints are Legal in California/US and are a Proven
Product
Boaters have Serious Concerns about Switching from Copper-Based
Paint to Non-Copper Paints
Non-Copper Paints are More Expensive and Require More Frequent
Cleaning.
Looking at lowering Copper levels in Paint and BMP's rather then

Looking Ahead
Urban Runoff Water Quality Challenges are most economically
handled through Community Education programs.
The next best option is Source Control .
Treatment options have the highest construction and
maintenance costs.
The 5t" Term NPDES Permit will probably require development of
various Implementation Plans to meet water quality standards.
If drought conditions persist, water quality impacts may continue
to decrease with a corresponding increase in the importance of
ensuring water supply.
Staff focus will need to adjust accordingly.
Looking Ahead
Reducing/Eliminating Trash is probably the Next Consented Effort.
Working with our upstream Agencies to capture trash from San Diego
Creek is an important way to improve water quality in the Bay.
Pesticides
In order to avoid future unknown issues and regulations (Bay
sediments, Bio-accumulation, ...), watershed-wide education and
efforts to control proper use of the new generation of pesticides will be
needed.
Trace Pollutants
With over 200 City storms drains emptying into the Bay, reducing dry
weather flows is the best way to reduce local water quality impacts at
the end of these drains.
