Dear Ms. Fu:
The Central Valley Clean Water Association (CVCWA) appreciates the opportunity to submit these comments on the tentative waste discharge requirements (Tentative Order) for El Dorado Irrigation District’s Camino Heights Wastewater Treatment Facility (WWTF). CVCWA is a non-profit organization representing more than 50 publicly owned treatment works throughout the Central Valley Region in regulatory matters affecting surface water discharge, land application, and water reuse. We approach these matters with a perspective to balance environmental and economic interests consistent with state and federal law. For the following
reasons, CVCWA respectfully requests that you revise the Tentative Order to reflect that the applicable water quality objective for electrical conductivity (EC) is a range, rather than 900 micromhos per centimeter (µmhos/cm).
