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.

Farm Evaluation/Nitrogen Management Plan Reporting Deadlines

The due date for the Farm Evaluation and Nitrogen Management Plan reporting, for the 2018 crop year, was March 1. We are extending the due date to allow full compliance for this regulatory reporting requirement. The Rice Waste Discharge Requirements (WDR) reporting website will remain open to July 31 to allow compliance through the end of planting and the application season. We are also sending non-compliance reminder letters to specific individuals.
