Waste Discharge Requirements


Water Quality Compliance – Rice Waste Discharge Requirements

The Central Valley Regional Water Quality Control Board (CVRWQCB) adopted the Rice Waste Discharge Requirements (Rice WDR) Order on March 27, 2014. Rice growers north of Sacramento submit the Farm Evaluation and the Nitrogen Management Plan to the California Rice Commission (CRC) annually by 1 March. As a mandatory requirement, the CRC must provide the CVRWQCB with the acreage not included in the Farm Evaluation Summary Report. The CVRWQCB will then proceed with further action.
