3. PROJECT DESCRIPTION evaluate the mineral resources of the State,including sources of construction aggregate. One of _ the purposes of this mandate, and of SMARA itself,is to protect significant mineral deposits from potential loss due to incompatible land uses. Based on State Mining and Geology Board guidelines, CGS is authorized to map regions within the State to classify areas with significant aggregate resources. The CGS Special Report 91-03,Mineral Land Classification: Aggregate Minerals of the South Tracy Site, San Joaquin County indicates that different areas of the project site have various mineral land classifications. The eastern area of the project site has been classified as MRZ-3 (areas containing mineral deposits the significance of which cannot be evaluated from available — data),the southwest section has been classified as MRZ-2(areas where adequate information indicates significant mineral deposits are present, or where it is judged that a high likelihood exists for their presence), with the remaining portions of the site being classified as MRZ-1 (areas where adequate information indicates that no significant mineral deposits are present or where it is judged that little likelihood exists for their presence). SMARA requires the preparation of an acceptable reclamation plan and financial assurances for all surface-mining operations. Reclamation plans are developed to meet various performance standards for the protection of wildlife habitat,revegetation, recontouring,erosion control,etc. as well as to eliminate or reduce residual public health and safety hazards and minimize environmental effects. The applicant and its consultants have prepared a reclamation plan for the project site dated October 2003 pursuant to the requirements of SMARA and the County's mining ordinance. The Project Site would require discretionary agency approvals for the actions listed below; • San Joaquin County—certification of the RMC Pacific Vernalis Quarry Mining and _ Reclamation Project EIR. • San Joaquin County—approval of the Quarry Excavation Permit,the reclamation plan, and financial assurances for the project that must be in conformance with SMARA, the — State Mining and Geology Board regulations for surface mining and reclamation practice (CCR Title 14,Ch. 8, Article 1, §3500 et seq; Article 9 §3700 et seq.)and San Joaquin County ordinances. • Stanislaus County—approval of the Surface Mining Use Permit,the reclamation plan,and financial assurances for the project that must be in conformance with SMARA, the State Mining and Geology Board regulations for surface mining and reclamation practice(CCR Title 14,Ch. 8,Article 1, §3500 et seq;Article 9§3700 et seq.)and Stanislaus County ordinances. • Regional Water Quality Control Board(RWQCB)—National Pollutant Discharge Elimination System(NPDES)permits under Section 402 of the Clean Water Act(CWA). Under the NPDES permit a Storm Water Pollution Prevention Plan (SWPPP)must be _ prepared before any construction activities begin.
