M. ENVIRONMENTAL SETTING IMPACTS AND MITIGATION MEASURES <br /> F. HYDROLOGY AND WATER QUALITY <br /> management. Beneficial uses of surface waters are described in the Basin Plan and are <br /> designated for major surface waters and their tributaries. In addition to identification of <br /> beneficial uses, the Basin Plan also contains water quality objectives that are intended to protect <br /> the beneficial uses of the Basin. <br /> Designation of beneficial uses defines the resources,services,and qualities of the aquatic system <br /> that are the ultimate goals of protecting and achieving high water quality. The Regional Board <br /> has set water quality objectives for all surface waters in the region concerning bacteria, <br /> bioaccumulation,biostimulatory substances,color, dissolved oxygen,floating material, oil and <br /> grease,population and community ecology,pH, salinity,sediment, settleable material, <br /> suspended material,sulfide, tastes and odors,temperature, toxicity,turbidity,and ammonia. <br /> Objectives for specific chemical constituents are also regulated dependent upon the beneficial <br /> use of the water body. Water quality objectives for groundwater concerning bacteria, organic <br /> and inorganic chemical constituents,radioactivity,taste, and odor are also listed. <br /> NPDES Permits <br /> Construction Stormwater <br /> Any construction activity, including grading,clearing,excavation, or other earth moving process <br /> may require an NPDES storm water permit for construction under the NPDES Storm Water <br /> Program. The Regional Board administers the NPDES stormwater-permitting program in the <br /> Central Valley Region. Construction activities of five acres or more are subject to the permitting <br /> requirements of the NPDES General Permit for Discharges of Storm Water Runoff Associated <br /> with Construction Activity(General Construction Permit). The project applicant must submit a <br /> Notice of Intent(NOI)to the Regional Board to be covered by the General Permit prior to the <br /> beginning of construction. The General Construction Permit requires the preparation and <br /> implementation of a Storm Water Pollution Prevention Plan(SWPPP), which must be prepared <br /> before construction begins. Implementation of the plan starts with the commencement of <br /> construction and continues though the completion of the project. Upon completion of the <br /> project,the applicant must submit a Notice of Termination to the Regional Board to indicate that <br /> construction is completed. <br /> Industrial Stormwater <br /> The regulations defining "storm water discharges associated with industrial activity" were <br /> published on November 16, 1990, with the Environmental Protection Agency identifying eleven <br /> categories of industrial activities that are required to obtain permit coverage under the NPDES <br /> Storm Water Program. Facility operators must submit a Notice of Intent for each industrial <br /> facility along with a site map and application fee. All storm water discharges from industrial <br /> sites must meet all applicable provisions of Sections 301 and 402 of the Clean Water Act. These <br /> provisions require control of pollutant discharges using best available technology economically <br /> achievable(BAT)and best conventional pollutant control technology (BCT)to prevent and <br /> reduce pollutants and to meet water quality standards. Stormwater discharges from an industrial <br /> site shall not cause or contribute to a violation of all applicable water quality standards, which <br /> include all federal receiving water standards and all state standards under the Regional Board <br /> Stockton Scavenger Transfer Station Expansion III.F.4 ESA 1990190 <br />
