The City of Vacaville is intending to construct a number of improvements at the City's Easterly Wastewater Treatment Plant (EWWTP) necessary to respond to regulatory and permit requirements, including compliance with numerical ammonia limits, nitrate limits, elimination of blending and dry wather filtration / Title 22 reclamation. These plant upgrades are collectively referred to as the "Tertiary Treatment Project". The EWWTP provides service to developed areas within the City limits of Vacaville and also provides service to the unincorporated community of Elmira. The EWWTP currently discharges treated wastewater effluent to Old Alamo Creek; such discharge being regualted by a NPDES permit from the Central Valley Regional Water Quality Control Board (CVRWQCB). On April 25, 2008, the CVRWQCB issued Waste Discharge Order No. R5-2008-0055. NPDEA Permit No. CA007769 which requires the City to implement the upgrades to the treatment plant identified in the Tertiary Treatment Project. In addition, as part of the project, the City will be implementing modifications to some of the existing facilities to improve operational efficiency, and address reduction to certain odr, light/glare and noise concerns that have been expressed to the City.
