` SWO KEI-P89-1104 .P1 November 22 , 1989 Page 3 determined by composite sample laboratory results, will be sent to a Class I disposal site. All non-hazardous ex- cavated soil will be: 1) sent to a Class II disposal site, 2) retained on-site for aeration and re-sampling; or 3) sent to a Class III landfill. The portion of non-hazardous stockpiled soil sent to each disposition will be based on laboratory results, and volume considerations. A permit to aerate will be obtained from the San Joaquin County Air Pollution Control District. 6. In addition, a measurement of ground water static level will be taken from the existing on--site well. A water sample will also be collected and analyzed for TPH as gasoline, BTX&E using EPA method 503 . 1, halogenated hydrocarbon using EPA 502 . 1, EDS using EPA 504 and TEL using DHS-LUFT. 7 . Phase I will begin the week of November 27, 1989 . PHASE II - GROUND WATER INVESTIGATION Upon completion of Phase I as described above, KEI will develop a work plan to investigate potential ground water contamination. Potential ground water contamination will be evaluated through the installation of monitoring wells. The work plan defining monitoring well locations and installation details will be submitted to the regulatory agencies by mid-February. PHASE III Phase III will discuss the alternatives for continuing the subsurface investigation if Phase II reveals contamination levels in the ground water significantly in excess of action levels. Phase III will include a proposal for additional monitoring wells to define a zero line of ground water contamination. It will also propose a ground water monitoring and sampling program for the wells installed during Phase II. The main purpose of Phase III will be to establish a zero kine of ground water contamination. The proposal/work plan will be submitted to the regulatory agencies by mid-July_ 1990, dependent on timely acquisition of the permits required to complete Phase II.
