s <br /> NEIMIgN-�lE1NE1 <br /> Mr. Roy Knight <br /> 24 October 1997 <br /> Page 4 <br /> Because our analyses are being conducted for the purposes of defining the extent of <br /> contamination, we are not proposing to verify detections of MTBE by using other analytical <br /> methods such as EPA 8260. <br /> After completing the investigation of the drain inlets a remediation plan will be developed. This <br /> plan will summarize the results of the soil sampling and recommend the extent of excavation that <br /> is appropriate for removing the contaminated soil. The plan will also include a description of <br /> the sampling that will be conducted to demonstrate that the remediation activities were adequate <br /> for cleaning up the contaminated soil. <br /> PHASE H— DRAIN INLET REMEDIATION AND STROM DRAIN CLEANING <br /> After receiving agency approval on the proposed remediation plan, the approved plan will be <br /> implemented. Following the completion of the remediation of the drain inlets, the drain inlets <br /> will be replaced with concrete-bottomed catch basins, and the storm drain lines will be pressure <br /> washed to remove the accumulated sediments. A report will be submitted after the excavation is <br /> completed to demonstrate that remediation was completed to acceptable levels. <br /> SCHEDULE <br /> The following schedule(subject to limitations imposed by the upcoming rainy season) is proposed <br /> for the two phases: <br /> Phase I <br /> Beginning of Field Investigation: One week following Agency approval <br /> Receipt of Laboratory Results : One week after sample collection <br /> Submission of Remediation Work Plan: One week after receipt of laboratory analyses <br /> Agency Approval of Work Plan: One week after submission of work plan <br />
