PROBLEM: WHAT IS STORMWATER POLLUTION?
Stormwater pollution is urban runoff water that has
picked up pollutants as it flows through the storm drain
system-a network of channels, gutters and pipes that
collect runoff from city streets, neighborhoods, farms,
construction sites and parking lots-and empties directly
into local waterways.
sewage, which goes to treatment plants, urban runoff
flows untreated through the storm drain system. Anything
thrown, swept or poured into the street, gutter or a
catch basin-the curbside openings that lead into the
storm drain system-can flow directly into our channels,
creeks, bays and ocean. This includes pollutants like
trash, pet waste, cigarette butts, motor oil, anti-freeze,
runoff from pesticides and fertilizers, paint from brushes
and containers rinsed in the gutter and toxic household

Stormwater Pollution Affects Anaheim Residents.
Contaminated urban runoff is an uncontrolled
nonpoint source of pollution into local waters, and
may contribute to beach closures. Litter, leaves and
other debris clog catch basins, causing flooding when
Stormwater Pollution Affects Anaheim Businesses.
Stormwater pollution may contribute to beach
closures, which hurt local businesses, tourism and Orange
County's image as a desirable place to live and work.
It is illegal for businesses without a permit to discharge
wastewater or other materials into the storm drain system.
Answer: Preventing Stormwater Pollution.
Everyone in Anaheim can help prevent stormwater
pollution. It is often caused by everyday behavior that
you may not realize contributes to the problem. Simple
behavior changes are all it takes to prevent stormwater
pollution, if we all do our part. Find out how.

Federal Water Pollution Control Act prohibits the discharge
of any pollutant to navigable waters from a point source
unless the discharge is authorized by a National Pollutant
Discharge Elimination System (NPDES) permit.
The 1987 passage of the Water Quality Act established
NPDES permit requirements for discharges of stormwater.
The NPDES permit program controls water pollution by
regulating point sources that discharge pollutants into
waters of the United States.
facilities and construction sites are regulated by the
State Water Resources Control Board, through general
stormwater permits. Cities and counties are regulated
through permits issued by the Regional Water Quality
Control Boards. Since 1990, operators of large storm
drain systems such as Anaheim's have been required to:
a stormwater management program designed to prevent
harmful pollutants from being dumped or washed by
stormwater runoff into the stormwater system, then
discharged into local waterbodies; and
a National Pollutant Discharge Elimination System
NPDES permit programs in California are administered
by the State Water Resources Control Board and by nine
regional boards that issue NPDES permits and enforce
regulations within their respective region.
lies within the jurisdiction of the Santa Ana Region.
This regional board issues permits to the Orange County
Permittees, which includes the County of Orange, Orange
County Flood Control District and incorporated cities
of Orange County. Since the program's inception, the
County of Orange has served as the "principal permittee".
following documents describe the regulations and programs
for water quality in Orange County.
The document for each region of the State Water
Quality Board's jurisdiction, Santa Ana and San Diego,
is the Water Quality Control Plan, commonly referred
to as the Basin Plan. It is the foundation for the regulatory
programs of each regional board. The Basin Plan documents
the beneficial uses of the region's ground and surface
waters, existing water quality conditions, problems,
and goals, and actions by the regional board and others
that are necessary to achieve and maintain water quality
National Pollutant Discharge Elimination System (NPDES)
The permits of each region outline additional steps
for a storm water management program and specify requirements
to help protect the beneficial uses of the receiving
waters. They require permittees to develop and implement
Best Management Practices (BMPs) to control/reduce the
discharge of pollutants to waters of the United States
to the maximum extent practicable (MEP).

The Annual Status Report is a requirement of the NPDES permit for submittal to the Regional Boards and United States Environmental Protection Agency. The report presents an analysis and assessment of permit compliance activities for the past fiscal year as required by the permits.
