Current through Register 2024 Notice Reg. No. 38, September 20, 2024
The following are changes to regulatory provisions in the 1991 Water Quality Control Plan for the Colorado River Basin Region (Basin Plan). The surface water objectives for temperature, suspended solids, and settleable solids were changed by removing the words "point source". These objectives will now apply to nonpoint and point sources. The waiver for application of the bacteria objective was changed by adding the word "existing". Consequently, only existing point source discharges are now eligible for the waiver, while new point source discharges are not eligible. New language was added that contains numeric objectives for selenium (0.005 mg/L four-day average, 0.02 mg/L one-hour average) which apply to all surface water tributaries to the Salton Sea. Further, new language was added to address:
1. the regulation of sludge applications;
2. storm water pollution;
3. Regional Water Quality Control Board, Colorado River Basin Region's guidelines and the general permit for septic systems; and
4. the State Water Quality Certification Program.
1. New article 7 and section filed 8-3-94; operative 8-3-94. Resolution No. 93-145 adopted by Colorado River Basin Regional Water Quality Control Board 11-17-93. Resolution No. 94-18 adopted by State Water Resources Control Board 2-17-94. Approved by OAL pursuant to Government Code section 11353 (Register 94, No. 31).
