Deadline to submit data to CRC is February 27, 2026, for certain growers.
The California Rice Commission has a Surface Water Quality Management Plan for Pyrethroids for rice acres that drain to the monitoring locations at upper Colusa Basin Drain (CBD5) and the Sacramento Slough near Karnak (SSB). The upper Colusa Basin Drain (CBD5) sub-watershed is generally west of the Sacramento River and north of Highway 20. The Sacramento Slough (SSB) sub-watershed is generally east of the Sacramento River, west of the Feather River, and south of the Sutter Buttes.
Part of the Management Plan’s Implementation Report (MPIR) requires growers within these two sub-watersheds to report on their pyrethroid use and management practices.
If you received a letter or an email from the CRC requesting you provide the required information, you can go to the link here to complete CalRiceNews.org
Alternatively, you can go to CalRiceNews.org and select the button “Pyrethroid Use Reporting”. If you did not receive a letter or email from the CRC, you are likely not required to report.
The requested information in based on the 2025 rice fields associated with the county’s pesticide use permits. The process will take only a few minutes to complete. Information submitted to the Water Board is in summary format only (no names, addresses or identifying information). Please complete the information no later than February 27, 2026.
Failure to meet to the pyrethroid monitoring objectives (established by the Water Board) at CBD5 and SSB could result in further potential measures to gain compliance, such as expanded monitoring, NOIs before applications, increased inspections, limited acreage application, or in extreme cases expulsion of farms from the coalition that are in gross violation of label requirements and Rice Waste Discharge Requirements (WDR) conditions.
