The exceedances in the Colusa Basin Drain have continued through the end of May as reflected in the most current monitoring results received by our office. All total, there have been five drain exceedances of the performance goal from May 19 to 28.
Our concern goes beyond attempts to preserve the current use of thiobencarb. The rice industry’s credibility is at stake as a third party capable of managing the only commodity specific coalition under the Waste Discharge Requirements.
To demonstrate our level of responsiveness, we implemented the following:
- eCom announcement of the exceedances on Friday, May 29
- Communication with the county agricultural commissioners, Department of Pesticide Regulation, CH2M Hill contractors, City of Sacramento, Valent, and the Central Valley Water Board
- Review of information from the Colusa County Agricultural Commissioner on thiobencarb use within the county and north of the drain site with anticipated release dates
- Sampling at seven sites north of the Colusa Basin Drain with an expedited lab analysis
- From the results, we will determine follow-up monitoring
- The CRC mailed a notification letter to Colusa and Glenn County rice growers
- Discussion at the CRC Board meeting on June 3
We would have never been able to implement this level of responsiveness without the structure of the CRC, and from the process of leadership provided through the Industry Affairs Committee and the CRC Board of Directors.
