Storm Water Management Plans
A Storm Water Management Plan (SWMP) is designed to provide guidance for park staff
to effectively implement a storm water program. The purpose is to define expectations and
direction for those responsible for developing and implementing the storm water program.
Elements outlined in a SWMP may include training or site-specific structural and nonstructural
Best Management Practices (BMPs) intended to reduce or eliminate pollutant
discharges from SVRAs. SWMPs typically include six minimum control measures. These are:
•§
public education and outreach,
•§
public involvement and participation,
•§
illicit discharge detection and elimination,
•§
construction site runoff,
•§
post-construction runoff, and
•§
pollution prevention/good housekeeping.
OHMVR Division SWMPs may also include management goals and activities for maintaining
OHV trails and facilities as they relate to meeting the park’s water quality objectives.
SWMPs come in various forms throughout the OHMVR
Division. Two of the SVRAs, Carnegie and Oceano Dunes,
operate under the California State Water Resources Control
Board’s (SWRCB) Water Quality Order No. 2013-0001-
DWQ and the National Pollution Discharge Elimination
System (NPDES) General Permit No. CAS000004 for
Waste Discharge Requirements (WDRs) for Storm Water
Discharges from Small Municipal Separate Storm Sewer
Systems adopted on February 5, 2013 (General Permit)
as non-traditional permittees. This permit regulates storm
water discharges from municipal separate storm sewer
systems (MS4s). Although it is not a requirement for
non-traditional Phase II permittees to develop a SWMP,
the OHMVR Division is developing a voluntary statewide
SWMP for all SVRAs.
Storm Water Management
An MS4 is defined by the Environmental Protection Agency (EPA) as a “conveyance or
system of conveyances (including roads with drainage systems, municipal streets, catch
basins, curbs, gutters, ditches, man-made channels, or storm drains): (i) owned or operated
by a state, city, town, borough, or county.” MS4 permits prescribe a storm water program
with the goal of reducing the discharge of pollutants to the maximum extent practicable.
The intent of this program is to protect the park’s natural resources, improve water quality,
