Syar Napa Quarry Project

Napa County has completed a Draft Environmental Impact Report (DEIR) analyzing the potential environmental impacts of the Syar Napa Quarry Expansion and Surfacing Mining Permit project, which provides for an approximate 124-acre expansion of the surface mining and reclamation plan associated with aggregate processing, production, and sales. The project would expand the existing 497-acre Syar Napa Quarry and allow mining to continue for a 35 year term, including an increase in the mining depth from between approximately 300 feet and 150 feet above mean sea level (msl) to no greater than 50 feet above msl, and an increase in sales of aggregate and aggregate related materials from current levels of approximately 1 million tons per year up to approximately 2 million tons per year.  The Syar Napa Quarry project site is located on the east side of State Highway 221 at its intersection with Basalt Road (between Kaiser Road and Streblow Drive).



The public comment period for the DEIR began on September 6, 2013 and has been extended to Dec 5, 2013. Please submit written comments on the DEIR by 5:00 PM on December 5, 2013 to:
