STAFF REPORT FORWARD, INC., CLASS II-1 DISPOSAL SITE SAN JOAQUIN COUNTY Facility Setting Forward, Inc., operates A Class II-1 waste disposal facility on Austin Road, seven miles southeast of Stockton (see Attachment) . The South Fork of Littlejohns Creek traverses the southern portion of the 157 acre site. Semiconfined major ground water supplies, used for domestic and agricultural purposes, lie below 178 feet. Discontinuous zones of perched ground water are reported between depths of 55 and 60 feet. Land within 1,000 feet of the site is used for agriculture. Existing Monitoring Program Forward, Inc. 's current Monitoring and Reporting Program was adopted on 23 March 1973 as part of their Waste Discharge Requirements Order No. 73-183. The program consists of monitoring ground water, disposal trench leachate, and quantities of Group 1 and Group 2 solid wastes. There were originally nine monitoring wells installed at the site (see map *in proposed Monitoring Program) . However, due to well design and construction., expansion of the facilities, and accidental loss, only two wells are .presently functional . Well Nos. 7 and 9 have provided the majority of the ground water data since the end of 1980. Leachate detection systems- have been installed in all group 1 disposal trenches. This system consists of perforated PVC pipes placed on the bottom of trenches and sloped to a collection sump. A riser pipe extends from the sump to above the ground surface to facilitate sampling and removal of the leachate. The waste generators are required to provide analysis and volume of all group 1 wastes that are to be discharged at Forward's site. Forward is, in turn, respon- sible for the review of this analysis to see if the material complies with their Interim Discharge Specifications. Forward is not required to submit the analyses in their quarterly monitoring reports, but is required to submit the quantity and disposal location.. Proposed Revisions to the Monitoring Program The current ground water monitoring system has not detected a water quality problem. However, in an effort to upgrade the system to obtain better information ' and meet more stringent state and federal regulations, we see the need to revise the current program. We are proposing that seven additional monitoring wells be installed at locations already approved by Forward,, Inc. The locations of the wells are shown in the proposed Monitoring Program. We expect this system will meet RCRA' Interim Status Document Requirementsand also the revised Subchapter 15 requirements which we expect to be adopted early next year by the State Board.
