~, Er E�7 NOTICE OF PUBLIC REVIEW PERIOD APR 0 FOR THE DRAFT ENVIRONMENTAL IMPACT RE POI� 'FSERVUS , 4'�1 HEAL]H VERNALIS WEST AND EAST PROJEM00 i NOTICE IS HEREBY GIVEN that the above document is available for review and comment. The review period begins 1' April 6, 2007 and ends on May 21, 2007. San Joaquin County has prepared a Draft Environmental Impact Report (DEIR)to consider.the potential environmental effects of the proposed Vernalis West and East Project. The ptoposed project requires the following actions:Certification of the Draft Environmental Impact Report;Approval of a conditional use permit(CUP)for mining of Vernalis West&East by the San Joaquin County Planning Commission,approval of a reclamation plan for Vernalis West& East by the San Joaquin County Planning Commission, approval of financial assurances for Vernalis West& East by the San Joaquin County Community Development Department, approval of improvement plans for Vernalis West&East by the San Joaquin County Community Development Department;approval of an encroachment permit for the conveyor undercrossing of Bird Road by the San Joaquin County Public Works Department, and approval of Waste Discharge Requirements by the Central Valley Regional Water Quality Control Board for the increased discharge of washwater at Vernalis Central to settling/recycling ponds and for the discharge of thickened washwater for reclamation of the Phase A mining area. The proposed project includes a phased Quarry Excavation application for a Quarry Excavation Permit to mine and reclaim approximately 790 acres of Portland cement concrete(PCC)quality aggregate reserves on the approximately 1,071-acre project site. Located immediately west and southeast of the existing Vernalis Central site. The proposed mining sites,also known as Petz,Elissagaray,Thoming,Fornaciari,Raspo South,Raspo Lease,Cose,and Weisenberger (mining accessory uses only), based on their prior ownership,are referred to collectively as Vernalis West and East, which reflects their location relative to Teichert's existing Vernalis facility. In addition, 26 acres of the project site (Weisenberger property)located immediately east of the California Aqueduct and west of Interstate 5(1-5)are proposed to provide additional space for operational and manufacturing support functions(e.g., stockpiles,precast, equipment storage). Individual properties within Vernalis West and East are referenced both by their prior ownership and phase designation(A, B, C, and D). Project components include mining,conveyance to the processing facilities, accessory support uses;third party transport of products to the market and reclamation.Mining would occur in four phases'and take approximately 40 years to complete. Maximum mining depths for each phase range from 110.feet to 225 feet below current grade. Materials mined at Vernalis West and East would be transported via electric conveyor to Teichert's existing Vernalis facility for processing and sale. The estimatedyield of Vernalis West and East is approximately 142 million tons of processed aggregate. This would increase the existing plant output from approximately four million tons per year to six million tons per year. The reclamation plan would return approximately 345 acres of the mine extraction area to the original dry grazing use at the existing grade with remaining 445 acres reclaimed below grade. The Draft EIR determined that the proposed project would be expected to result in a significant and unavoidable impact to cumulative air quality, cumulative LOS at eastbound SR 132 east of the Bird Road interchange,cumulative LOS at weaving operations on SR 132 between I-51Bird Road Interchange,cumulative LOS at the westbound on-ramp from Bird Road,and cumulative LOS at the eastbound off-ramp to Bird Road. The proposed project site is not present on any of the lists of sites enumerated under Section 65962.5 of the Government Code including, but not limited to lists of hazardous waste facilities, land designated as hazardous waste property, hazardous waste disposal sites,and others. Copies of the DEIR are available far review at the Community Development Department.Reviewers should focus on the adequacy of the DEIR in discussing possible impacts upon the environment,ways in which adverse effects might be minimized,and alternatives to the proposed project. Reviewers who wish to comment on the DEIR are urged to submit written comments to:Kevin Swanson,San Joaquin County Department of Community Development, i S 10 E. Hazelton Ave, Stockton, CA 95245, (209)468-3124. Written comments must be submitted prior to 5.:00 pm May 21,2007: - an-Joaqum County Department 6f C6fti unityDevelopment
