Analysis Background This project application was submitted in December 2001. A similar application for a Surface Mining Use Permit was submitted to the Stanislaus County Department of Planning and Community Development in June 2002 for the portion of the project located in Stanislaus County. In October of 2003 a revised application and reclamation plan was submitted. The Draft Environmental Impact Report was completed in May of 2006 and the Final Environmental Impact Report was completed in June 2008. The proposed CEMEX Vernalis Quarry is to replace the Huck Quarry located on the east side of Tracy Boulevard, one mile south of Linne Road, south of Tracy. That facility is expected to be closed within the next ten years. Environmental Review A Draft EIR was prepared for this project. A 45-day public review period was provided in accordance with CEQA. All comments have been responded to and a Final EIR has been prepared for consideration by the Planning Commission. The Final EIR includes the Draft EIR by reference. The Final EIR, including the response to comments and the Draft EIR, is provided under separate copy. The EIR determined that he project would result in significant and unavoidable impacts relative to noise and air quality. The project would also contribute to cumulative significant and unavoidable impacts relative to noise and air quality. Finally, the EIR determined that there were no growth inducing impacts. The EIR reviewed the environmental issues associated with two mining options. In the first option (the project) no excavation is allowed in or near Hospital Creek. In the second option, mining occurs in the current creek area. The EIR determined that the second option would result in significant unavoidable hydrologic impacts, so the applicant chose to proceed with the first option. This staff report is for the first option that avoids the creek. The Draft EIR originally addressed reviewed three traffic route options. For various reasons, option two was eliminated and will not be further discussed in this report. Option one requires the construction of the Interstate 5/Blewett Road interchange. Option three would provide access to the site without the interchange (see Figures Revised 4.4-3a and Revised 4.4-3b). A brief discussion of the environmental issues is provided below. Air Quality The project would have potentially significant impacts relative to project construction, project operation- phased emissions, project diesel particulate matter(DPM). After mitigation, project construction and DPM impacts would be less than significant. However, air quality impacts related to project operation-phased emissions would remain significant even after implementation of Best Available Control Technologies (BACT). Reactive Organic Gas(ROG) emissions would be just above significance levels in 2008 for annual production levels of 4 million tons. Nitrogen Oxides(NOx)emission would be 4 to 14 times above the significance criterion under various scenarios analyzed in the EIR. Air quality impacts after mitigation remain significant.
