FOOTHILL SANITARY LAND FILL, Inc. Refuse Disposal Site for San Joaquin County POST OFFICE BOX 1528 - STOCKTON, CALIFORNIA 95201 TELEPHONE 20946&5089 7 N, January 2, 1991 ENI Ron Valinoti San Joquin County Public Health Services Environmental Health Division P.O. Box 2009 Stockton, CA 95201 Subject: Foothill Landfill Winterization Plan, 1990/1991 This letter describes the winterization procedures that havr- been implemented at the Foothill Landfill for the winter of 1990/1991. The winterization activities were completed in earl October, before the rainy season began. I The winter dumping area is located at the southeast corner of the permitted site, where a pit has been excavated to an approximate depth of 50 feet, a width of 300 feet, and a length *f approximately 600 feet. See the attached map for the locatio of the dumping area. The 300 -foot width provides enough room to accommodate both the private and commercial vehicles safely. I The access roads have been built of rock and gravel to a width of approximately 40 feet, making them wide enough for two- way traffic. One of these roads provides access to the bottom of the dumping pit. The dumping pad has been built with a mixture of sand, cement and broken tiles, which when compacted becomes an asphalt - like surface. The trench and fill landfilling method is used. Waste is spread and compacted in an excavated trench. The trench is expanded each day to provide dumping space, and the native soi that is removed is used for daily cover. There is no need to stockpile cover soil because it is generated continuously by t trench excavation. In the event that additional road material is needed it will be purchased from El Rancho Rock and Gravel less than a mile from the site.
