Before any ground-disturbing

Pollution Control Plan (WPCP)
that includes erosion control
measures and construction
waste containment measures
to ensure that local waterways
are protected during and after
construction. The WPCP shall

version of the California
Stormwater Quality Association
(CASQA) BMP Handbook. The
WPCP shall include site design
to minimize offsite storm water
runoff that might otherwise
affect adjacent lake or stream
habitat.
The WPCP shall require that the
construction contractor
implement BMPs to protect
water quality within the various
watercourses of the project.
CASQA has developed
