Grower Reporting Requirements for Waste Discharge Requirements Orders

sunset over the rice fields

March 1 is historically the due date for reporting the Farm Evaluations, Nitrogen Management Plans and various other information for the Waste Discharge Requirements (WDR) Order. No rice reporting is due this year, so look for notices in 2022 as a reminder to report that rice crop year in 2023.

The WDR Orders were amended in 2018, resulting in changes to the grower reporting requirements. A table listing side-by-side requirements with the Rice WDR and the Sacramento River Watershed WDR, the coalition for non-rice crops, is our effort to provide you with current information. 

Please use the following information from the Sacramento River Watershed as reference and receive verification from either the third party represented by Northern California Water Association (NCWA) or the local subwatershed group proving program management in the area you grow non-rice crops. 

Sacramento River WatershedSacramento Valley Rice Growers
Notice of Confirmation/Notice of Intent/Membership Application
Automatic for rice growers with landowner notification in the Farm Evaluation
Farm Evaluation: 
Starting 1 March 2015
Low Vulnerability (SW/GW) every five years starting 1 March 2021
High Vulnerability (SW/GW) 1 March annually through 1 March 2018. By 1 March 2021, and by 1 March every five years thereafter.

Please check with the coalition leads to make certain you comply with the appropriate timeline(s).
Farm Evaluation: 
Starting 1 March 2015

“By 1 March 2018, and every five years thereafter, the Grower must update their Farm Evaluation and submit it to the California Rice Commission.”

This means the CRC WDR site will reopen in 2023, for reporting of your 2022 crop information.

Watershed/Subwatershed Based
Sediment and Erosion Control Plan:
Not required
Irrigation and Nitrogen Management Plan:
Applied/Removed Nitrogen Ratio
INMP must be Certified
Exceptions apply with data support
Irrigation and Nitrogen Management Plan:
No INMP for rice growers
Nitrogen Management Plan remains the same:
Submit online with the Farm Evaluation starting in 2023 for the 2022 crop information
No applied/removed ratios
No certification requirement
Drinking Water Supply Well Monitoring:

Drinking Water Supply Well Monitoring

Additional information and forms will be available in the CRC online continuing education program
The course will be two hours with one hour of continuing education accreditation for license renewal
Look for CRC e-communication (Jim Morris email) on the details and launch date

Implementation of additional management practices relies on the water monitoring results. Not meeting specific water quality objectives can result in the coalitions developing Surface Water and/or Groundwater Quality Management Plans. The coalitions could meet further requirements for developing Management Practices Evaluation Programs. Growers may need to develop Management Practice Implementation Reports. Fortunately, the rice growing area north of Sacramento does not have any high vulnerability areas that trigger these additional reporting requirements. 

For questions and additional information, please contact Roberta Firoved, Industry Affairs Manager at rfiroved@calrice.org or (916) 206-5039.

Thiobencarb Monitoring

Thiobencarb monitoring starts April 26 and ends June 28, 14 times at the four core sites. We base the monitoring on planting dates and timing of thiobencarb applications from the county agricultural commissioner offices sharing dates on the notices of intent. Some rice has been planted and treated, which will be captured with the current monitoring plan.
