reduce contaminants discharged into receiving water bodies.The NPDES municipal permit system is designed to reduce contaminant discharges in urban stormwater runoff and non-stormwater discharges and requires the SWMPs to address development and implementation of BMPs and measurable goals for the following six minimum measures,and include evaluation and reporting efforts: Public education and outreach, _ Public participation/involvement, Illicit discharge detection and elimination, Construction site runoff control, Post-construction runoff control in new development and redevelopment,and Pollution prevention/good housekeeping for municipal operations. All NPDES permits also have inspection,monitoring,and reporting requirements to ensure that BMPs are effective at controlling discharges of stormwater-related pollutants. In response to a court decision,the Central Valley RWQCB implemented mandatory water quality sampling requirements in 2001 (Resolution 2001-046)for visible and nonvisible contaminants in discharges from construction activities.Where nonvisible pollutants are known or should be known to be present and would likely cause a discharge, sampling and analysis is required. Other permits of the Central Valley RWQCB include a general NPDES permit for construction dewatering activity(Order 5-00-175)that authorizes direct discharges to surface waters of as much as 250,000 gallons per day for no more than a 4-month period each year.The general process for all NPDES permits is the same and includes submittal of Notices of Intent(NOls)to the Central Valley RWQCB to discharge and implementation of BMPs to minimize those discharges. The Central Valley RWQCB may also issue site-specific waste discharge requirements(WDRs),or waivers of WDRs,for certain waste discharges to land or waters of the state(e.g.,nonnavigable isolated ponds and wetlands, groundwater)that do not have the potential to enter waters of the United States(i.e.,navigable surface waters). In particular,Central Valley RWQCB Resolution R5-2003-0008 identifies activities subject to waivers of WDRs for a variety of activities,including minor dredging activities and construction dewatering activities that discharge to land. REGIONAL AND LOCAL REGULATIONS — San Joaquin General Plan 2010 The San Joaquin General Plan contains the following water quality policies that are applicable to the proposed proj ect. Infrastructure Services Chanter Policy 6.Water supplies serving new development shall meet state water quality standards. If necessary, water shall be treated to meet these standards. Water Resources and Quality Chanter • Policy 1.Water quality shall meet the standards necessary for the uses to which the water resources are put. • Policy 2. Surface water and groundwater quality shall be protected and improved where necessary. 1994 Mountain House Master Plan and Stormwater Management Plan The stormwater drainage system and water quality protection requirements for the Mountain House area were fust established in the MHMP and associated MHMP EIR.Mitigation Measure 4.4.3-1 identified in the Mitigation Monitoring Program for the MHMP described the stormwater management measures for water quality protection and were subsequently adopted as a component of the MHMP.
