Stormwater & Runoff Pollution Control Program

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 Stormwater Pollution Prevention Website, see the “Don’t Trash California” campaign, and get more information on keeping our neighborhoods, oceans, and local waterways clean.
