Box 2009 <br /> Sacramento, CA 95201 <br /> SUBJECT: Permit Application to Drill Soil Borings and Construct Ground-Water <br /> Monitoring Wells at Delta Truck Sales, Stockton, San Joaquin County, <br /> California <br /> Dear Ms. Reuss: <br /> Enclosed is a permit application, $35.00 permit fee, and a copy of a completed "Contractor <br /> Questionnaire", all submitted to obtain a permit for drilling soil borings and constructing <br /> ground-water monitoring wells at the subject location. The borings will be drilled to assess <br /> the lateral and vertical extent of hydrocarbons and/or other possibly hazardous materials <br /> in the soil surrounding the site of a former surface impoundment. Total depth of the <br /> borings is expected to be approximately 15 feet. The wells will be constructed to assess the <br /> ground water quality and gradient near the site of the former impoundment. Ground water <br /> is expected at approximately 70 feet, so the wells are expected to be drilled to 80 feet. <br /> We would like to schedule drilling as soon as possible. The borings will be drilled first, <br /> they probably can be completed in one day. The wells will be installed one to two weeks <br /> LuL a L' assershig the �)vririig 5011 sarnpie analydcai results. Your office shouid already <br /> have a work plan approved by the Central Valley Regional Water Quality Control Board. <br /> The soil borings proposed are not included in the work plan, but will be drilled and <br /> sampled similarly to those done in May 1990 near the fuel islands. We believe that this <br /> project does not come under the pilot program because underground storage tanks are not <br /> involved. <br /> 597 Center Avenue,Suite 350 Martinez,CA 94553 Phone(415)372-3637 Fax(415)372-3790 <br /> Formerly known as Hunter/Gregg,Inc. <br />
