r <br /> t + <br /> WASTE DISCHARGE REQUIREMENTS 2 <br /> FOR FOOTHILL SANITARY LANDFILL <br /> CLASS III LANDFILL <br /> SAN JOAQUIN COUNTY <br /> WASTES AND THEIR CLASSIFICATION <br /> 4. The Discharger proposes to continue to discharge municipal solid waste for disposal in <br /> the Class III landfill. These wastes are classified as "non hazardous solid waste" or <br /> "inert waste" using the criteria set forth in Chapter 15. The discharge rate is <br /> approximately 700 tons per day. <br /> SITE DESCRIPTION <br /> 5. Land within 1000 feet of the facility is used for agriculture. <br /> 6. There are several faults in the area, but the Bear Mountain Fault Zone, at a distance of <br /> about 12 miles from the site, would most likely be the source of the maximum <br /> probable earthquake of 5.7 on the Richter scale. This could produce an estimated <br /> peak bedrock acceleration, at the site, of 0.15g. <br /> 7. The first water bearing formation is about 100 feet below the base of the landfill. The <br /> hydraulic gradient is generally to the southwest. <br /> 8. The beneficial uses of ground water are domestic, municipal, agricultural, and <br /> industrial supply. <br /> 9. The facility receives an average of 17.5 inches of precipitation per year as determined <br /> from an isohyetal map of San Joaquin County developed from "Storm Drainage Study <br /> and Master Plan, San Joaquin County, January 1973". The mean evaporation for this <br /> facility is 78 inches per year as determined by the California Department of Water <br /> Resources for the station at the Oakdale Woodward Dam. <br /> 10. The 100-year, 24-hour precipitation event for the facility is 3.9 inches, based on data <br /> published by the California Department of Water Resources. <br /> 11. The facility is not within a 100-year flood plain. <br /> 12. Surface drainage is intermittent in nature, with storm waters draining generally in a <br /> westerly direction to enter the Delta via either Mormon Slough or Duck Creek. <br /> 13. The beneficial uses of these surface waters are domestic, municipal, agricultural, and <br /> industrial supply; ground water recharge; recreation; stock watering; aesthetic <br /> enjoyment; fresh water replenishment and habitat; spawning; wildlife habitat; and the <br /> preservation and enhancement of fish, wildlife and other aquatic resources. <br />
