Alquist-Priolo Fault Zoning Act The Alquist-Priolo Earthquake Fault Zoning Act was passed by the California Legislature to mitigate the hazard of surface faulting to structures. The main purpose of the act is to prevent the construction of buildings used for human occupancy on the surface trace of active faults. The act addresses only the hazard of surface fault rupture and is not directed toward other earthquake hazards. Local agencies must regulate most development in fault zones established by the State Geologist. Before a project can be permitted in a designated Alquist-Priolo Fault Study Zone,cities and counties must require a geologic investigation to demonstrate that proposed buildings would not be constructed across active faults. California Surface Mining and Reclamation Act The California Surface Mining and Reclamation Act(SMARA)was enacted by the State Legislature to regulate activities related to mineral resource extraction. The Act requires the prevention of adverse environmental effects caused by mining,the reclamation of mined lands for alternative land uses, and the elimination of public health and safety hazards from the effects of mining activities. At the same time, SMARA encourages both the conservation and production of extractive mineral resources,requiring the State Geologist to identify and attach levels of significance to the State's varied extractive resource deposits.Under SMARA,the mining industry in California must adequately plan for the reclamation of mined sites for beneficial uses and provide financial assurances to guarantee that the approved reclamation will actually be implemented. The requirements of SMARA must be implemented by the local lead agency with permitting responsibility for the proposed mining project. National Pollutant Discharge Elimination System Permit In California,the State Water Resources Control Board administers the federal Environmental Protection Agency promulgated regulations (55 CFR 47990)requiring the permitting of stormwater-generated pollution under the National Pollutant Discharge Elimination System(NPDES). In turn,the Board's jurisdiction is administered through Regional Water Quality Control Boards(RWQCBs). Pursuant to these federal regulations, an operator must obtain a General Permit under the NPDES Stormwater Program for all construction activities with ground disturbance of one acre or greater. The General Permit requires the implementation of Best Management Practices (BMPs)to reduce pollutant loads into the waters of the State and measures to reduce sediment and erosion control. In addition, a Storm Water Pollution Protection Plan(SWPPP)must be prepared. The SWPPP addresses water pollution control during construction. SWPPPs require that all storm water discharges associated with construction activity,where clearing, grading and excavating results in soil disturbances must by law,be free of site pollutants. City of Manteca General Plan Geologic and Seismic Safety The Safety Element of the City of Manteca General Plan(City general plan) outlines goals and policies associated with geology and soils. The following policies relate to the project: ► Policy S-P-1: The City shall require preparation of geological reports and/or geological engineering reports for proposed new development located in areas of potentially significant geological hazards,including potential subsidence(collapsible surface soils)because of groundwater extraction. ► Policy S-P-3: The City shall require new development to mitigate the potential impacts of seismic induced settlement of uncompacted fill and liquefaction(water-saturated soil)because of the presence of a high water table.
