TMDLs

The Total Maximum Daily Load (TMDL) process leads to a "pollution budget" designed to restore the health of a polluted or impaired body of water. The TMDL process provides a quantitative assessment of water quality problems, contributing sources of pollution, and the pollutant load reductions or control actions needed to restore and protect the beneficial uses of an individual waterbody impaired from loading of a particular pollutant.

Dairy Program

The Dairy Program for the North Coast Regional Water Quality Control Board currently regulates waste discharge from dairies under two orders: General Waste Discharge Requirements for Existing Cow Dairies in the North Coast Region, Order No. R1-2012-0002 (GWDR), and The Conditional Waiver of Waste Discharge Requirements for Existing Cow Dairies in the North Coast Region, Order R1-2012-0003 (Waiver).
