Dear Mr. Mamidi:
The Central Valley Clean Water Association (CVCWA) submits these comments in response to the Tentative Order to amend Waste Discharge Requirements Order R5-2010-0081 (WDRs) for the City of Rio Vista’s (City) Northwest Wastewater Treatment Facility. CVCWA is a non-profit organization representing more than 50 publicly owned treatment works throughout the Central Valley in regulatory matters affecting surface water discharge, land application, and water reuse. We approach these matters in a way that balances environmental and economic interests consistent with applicable law.
