Central Valley Diuron TMDL and Basin Plan Amendment
Subscribe on-line to our Central Valley Diuron TMDL and Basin Plan Amendment, electronic mailing list.
The goal of this project is to develop an amendment to the Basin Plan for Regional Board consideration. The amendment will be designed to establish water quality objectives and a program of implementation for the control of discharges of the herbicide diuron to surface waters in the Sacramento and San Joaquin River Basins of the Central Valley. The amendment will also be designed to establish Total Maximum Daily Loads for waterbodies that are listed for diuron on the 303(d) list, and establish provisions to address and/or prevent future diuron 303(d) listings. For additional information, please contact Melissa Dekar at (916) 464-4603, or firstname.lastname@example.org or Danny McClure at (916) 464-4751 or email@example.com.
