The Stormwater & Runoff Pollution Control Program
tracks industrial and commercial businesses in the unincorporated County area to
determine compliance with the provisions of the Municipal National Pollutant Discharge
Elimination System (NPDES) Permit issued by the California Regional Water Quality
Control Board, Los Angeles Region.
Visit the Water For Los Angeles Program,
see the “Don’t Trash California” campaign, and get more information
on keeping our neighborhoods, oceans, and local waterways clean.
Please contact your city to report a clogged storm drain, request storm drain stenciling, and learn about
what your city is doing to improve water quality.
