Easterly Wastewater Treatment Plant NPDES Permitting
City of Vacaville, California

The NPDES permit assistance performed by West Yost for the City of Vacaville included preparation of a Report of Waste Discharge and NPDES permit application, and subsequent negotiations with the Regional Board regarding the NPDES permit requirements. The NPDES permit adopted was the first permit in the State to incorporate the requirements of the Policy for Implementation of Toxics Standards for Inland Surface Waters, Enclosed Bays, and Estuaries of California, 2005 (SIP).

While the City and West Yost adopted a largely non-confrontational approach to the permit negotiations, the permit was nevertheless contested before the State Board. In doing so, the City and West Yost enlisted the assistance of some of the top wastewater experts in the State, as well as interested parties including the County Sanitation Districts of Los Angeles. West Yost also worked closely with the City’s environmental attorney.

A strong case was made before the State Water Resources Control Board demonstrating that the new discharge limits would require a major increase in new facilities at a huge cost to the City, with little or no corresponding environmental benefits. Most of the more onerous limits and requirements of the permit have been stayed, and the associated time schedules of the permit no longer apply.
