Williams ACCOMPANIED BY: Doug O'Neal (Dept. of Health Services) OBSERVATIONS AND COMMENTS: This inspection was conducted as an annual inspection required by Section 25208.7(a) of the Toxic Pits Cleanup Act (TPCA) . Within the past year, the facility has submitted many documents, including a Ground Water Assessment Plan and a Closure Plan. Drilling activities for Phase I of the ground water assessment were conducted from March to July of 1989. The Ground Water Assessment Report was submitted on 2 October 1989. The Closure Plan was submitted on 30 May 1989 and contained a soil assessment plan for the pond areas and four closure alternatives. The final closure alternative will be selected based on the results form the soil assessment. Closure waste discharge requirements which included a time schedule and monitoring order, were prepared and Order No. 89-163 was adopted on 22 September 1989. Implementation of the Closure Plan had already begun. The clearing of the ponds for the soil assessment began on 15 September 1989. On the day of the inspection, Pond 2S was being cleared of brush and other vegetation. Pond 2N had previously been cleared and soil borings samples were being collected at three intervals (surface, 2.5 - 3.0 feet and 5.0 - 5.5 feet). Hargis will take composite samples of each bin of mulch to be analyzed for heavy metals and volatile organic constituents (VOCs) . The deep soil boring in Pond 2N was moved to the central portion of the pond near the pipe inlet from the main factory building and near the location of the SNR sludge samples SL-13, 14, where copper and silver were found to be above hazardous total concentrations. The location was moved on agreement between Terry Turner of Hargis, Doug O'Neal and myself. The facility discontinued their galvanizing operation on 13 September 1989. This decision was made after the zinc flux tank developed a leak. All galvanizing will be performed off-site and the galvanizing building will be used for storage. I observed the potential location of the dry well , adjacent to the east side of the foundry building. A pipe leading from the upstairs laboratory sink was connected directly to the dry well which was covered with a steel plate. The laboratory sink was used for the disposal of wastes produced from tests on the foundry products. Later in the week, after the inspection, the area was investigated to confirm the location
