San Joaquin County Environmental Checklist <br /> Within the limits of ground disturbance of the area,there is no risk of naturally <br /> occurring large landslides,because the area is essentially flat and topographically <br /> featureless. Localized landslides as a result of project activities are discussed in <br /> the Impact Discussion. <br /> Land subsidence and volcanic activity are not significant concerns in the area. <br /> Regulatory Setting <br /> Federal Standards <br /> Section 402 of the Clean Water Act/National Pollutant <br /> Discharge Elimination System <br /> The federal CWA is discussed in detail in Section VIII,Hydrology and Water <br /> Quality. Because CWA Section 402 is directly relevant to excavation and <br /> grading,additional information is provided here. <br /> Amendments in 1987 to the federal CWA added Section 402p,which establishes a <br /> framework for regulating municipal and industrial stormwater discharges under the <br /> National Pollutant Discharge Elimination System(NPDES)program. As <br /> described in Section VIII,Hydrology and Water Quality,EPA has delegated to the <br /> State Water Resources Control Board the authority for the NPDES program in <br /> California,which is implemented by the state's nine Regional Water Quality <br /> Control Boards(RWQCBs). Under the NPDES Phase II Rule,any construction <br /> activity disturbing I acre or more must obtain coverage under the state's General <br /> Permit for Stormwater Discharges Associated with Construction Activity(General <br /> Permit). General Permit applicants are required to prepare a notice of intent(NOI) <br /> and a storm water pollution prevention plan(SWPPP)and to implement and <br /> maintain best management practices(BMPs)to avoid adverse effects on receiving <br /> water quality as a result of construction activities,including earthwork. <br /> State Standards <br /> Alquist-Priolo Earthquake Fault Zoning Act <br /> California's Alquist-Priolo Earthquake Fault Zoning Act(Pub.Res.Code Section <br /> 2621 et seq.),originally enacted in 1972 as the Alquist-Priolo Special Studies <br /> Zones Act and renamed in 1994, is intended to reduce the risk to life and property <br /> from surface fault rupture during earthquakes. The Alquist-Priolo Act prohibits the <br /> location of most types of structures intended for human occupancy across the <br /> traces of active faults and strictly regulates construction in the corridors along <br /> active faults(Earthquake Fault Zones). It also defines criteria for identifying active <br /> faults,giving legal weight to teams such as active,and establishes a process for <br /> reviewing building proposals in and adjacent to Earthquake Fault Zones. <br /> Notice of Preparation for the June 2006 <br /> North County Recycling Center and Sanitary Landfill 240 J8506307.06 <br /> Permit Revision <br />
