The Post Closure Permit will set <br />out maintenance requirements for the Class II -1 landfill which <br />has been closed in place as previously public noticed. <br />Background <br />Forward Landfill is located on 157 acres in eastern San <br />Joaquin County, approximately three miles east of Stockton. <br />The facility is on the west side of Austin Road, two miles <br />south of Arch Road and three miles north of Lathrop Road <br />(Figure 1). The maps of the facility are included: 1) <br />location map, 2) site features map, and 3) a site plan map. <br />Forward, Inc. began operating a Class II -1 waste disposal <br />facility and recycling center under a San Joaquin County <br />Conditional Use Permit (U-73-9) issued February 15, 1973. The <br />Regional Water Quality Control Board (RWQCB) issued Waste <br />Discharge Requirements (WDRs), Order No. 73-183, for the <br />facility on March 23, 1973. DHS issued a State Hazardous <br />Waste Facility Permit No. 39-0001-78 on August 31, 1979. New <br />WDRs, Order 88-023, were issued in 1988. <br />When Forward, Inc. received the Hazardous Facility Permit, <br />waste was being disposed of in three trenches within the <br />present Waste Management Unit A, (WMU-A). Most of this waste <br />was barium -strontium sludge (non -radioactive) from mining <br />operations. During early 1980, Forward constructed five solar <br />evaporation ponds, clay -lined, at the site of the present <br />WMU-D (Figure 2). The ponds were 10 feet deep and totaled <br />about two acres. The oil industry related waste placed into <br />the ponds consisted of drilling muds, fluids, and brines. <br />Some fuel oil wastewater was discharged to the ponds. <br />
