I-N� 'Iwo, <br /> During the removal of the associated water, tanks and piping, soil contaminated <br /> with diesel fuel was encountered. The source of this contamination is unknown <br /> at this time. The soils affected in the immediate tank and piping area were <br /> removed and stockpiled on site. The tanks and related piping have and are <br /> currently being disposed of as non-hazardous materials. Contaminated soils <br /> encountered were removed and placed on Visqueen. It is our intent to bio- <br /> remediate the ex-situ soil for reuse on the property (See attached <br /> laboratory results concerning the ex-situ contamination. <br /> Previously submitted as Appendix "A" to this work plan are figures 1 through 32 <br /> inclusive. These figures document the activities that were conducted at the site <br /> from June through December, 2002. <br /> SUMMARY OF WORK TO BE PERFORMED <br /> Based on preliminary analytical results obtained in the investigative activities in <br /> February it is obvious that a permit to drill and test is needed. We are requesting <br /> approval for the following geo-technical procedures to evaluate the extent of <br /> contamination at Teichert Tracy Rock facilities: <br /> 1. Use a 2" drilling rig with geo-probe for sampling <br /> 2. Use a PID (Photo ionic Detector) for on site testing of samples and <br /> boring depth control. <br /> 3. Take samples at 5' increments in contaminated zone. <br /> 4. Use GPS (Ground Position System) to provide locations of borings. <br /> 5. Use an independent Geologist for sampling. <br /> 6. Use an independent Laboratory to provide laboratory analysis of <br /> samples. <br /> 7. Use data to provide a "Voluntary" cleanup proposal. <br /> 8. Cap borings until proposal is made and plan of action is executed. <br /> Ground water was detected via sounding at 90 foot depth. It is our opinion <br /> that contamination did not reach ground water. After conformation that the <br /> plume did not reach ground water, and voluntary corrective action is taken, <br /> we would propose installing several wells based on size of plume, to prove <br /> water is not affected. If ground water is affected, a remedial monitoring and <br /> action plan will be submitted. Should ground water be detected during <br /> sampling, Ground water samples will be taken and ground water sampling <br /> wells will be installed. <br /> 5 <br />
