WASTE DISCHARGE REQUIREMENTS -5- FORWARD INC..FORWARD LANDFILL SAN JOAQUIN COUNTY 21. Surface drainage is to the South Fork of South Littlejohn Creek, which is tributary to South Littlejohn Creek, which flows into Littlejohns Creek, tributary to French Camp Slough,hence San Joaquin River and the Delta. 22. The beneficial uses of these surface waters are recreation, aesthetic enjoyment, and preservation and enhancement of fish, wildlife and other aquatic resources. 23. There are no known Holocene faults within 200 feet of the Forward facility. The closest active fault is the Greenville Fault which is approximately 28 miles west-southwest of the site. The Discharger estimates the highest local ground acceleration would come from an earthquake on the Midland fault 24 miles west of the site where the most recent displacement is estimated to be early Oligocene (35 million years ago). A maximum credible earthquake of magnitude 7.0 on the Midland fault would produce a ground acceleration of 0.18 g at the facility. OPERATION OF FACILITIES 24. The Discharger proposes to increase waste receipts to an average rate of 3,800 tons per day with a peak daily rate of 4180 tons per day. 25. The transfer station/ source recovery facility is south of Littlejohn Creek. The Discharger proposes to expand this facility from 12,000 square feet to 50,000 square feet. Processed materials include baled cardboard and paper, ferrous and nonferrous metals, glass. plastic and wood. Recovered wastewood. lumber, and brush are placed in a wood waste stockpile area, ground and processed in a wood grinder,then hauled off-site. Other recovered materials are stored on-site and shipped to market as needed. Remaining unrecyclable wastes are landfilled. 26. The following disposal rates are based on 1992 data. Asbestos is discharged to WMU D at a rate of about 7,000 cubic yards per month. Coal ash is placed in WMU E at a rate of about 2,600 cubic yards per month.Nonhazardous solid waste, primarily commercial waste, is discharged to WMU D at a rate of about 7,700 cubic yards per month. 27. The Discharger plans to expand the landfill units in five general phases with construction of modules within each phase. Future expansion north of the south fork of South Littlejohns Creek will be in WMU D with each module identified with the year of construction,e.g. WMU D93. The vertical expansion of WMU D over WMUs B. C, D87, D88N, D88S, D89 and Eastern Ash Disposal Pit WMU E occurs in Phase H.The lateral expansion of WMU D to the west happens in Phase III. The filling of WMU D to final grades occurs in Phase IV. The construction of WMU H, the landfill unit south of Littlejohn Creek,occurs in Phase V. The phases will not necessarily be completed sequentially.
