May 7, 2012 Dave Parker Parker Oceanic P.O. Box 182 Holt, CA 95234 Subject: Proposal to Remove Contaminated Soil and Asbestos Containing Material 8503 Windmill Cove Rd. near Stockton, California Dear Mr. Parker: Cook Environmental Services, Inc. (CES) is pleased to provide this proposal for the above referenced project. We hereby propose to furnish all labor, equipment, and materials to remove up to 40 cubic yards (CY) of oily contaminated soil and up to 1 CY of asbestos containing materials (ACM) from your property located at 8503 Windmill Cove Rd. near Stockton, California. We understand, this property was recently used to dismantle ships and the constituents of concerned identified during a survey of the site on April 20, 2012 are long-chain hydrocarbons in shallow soils. I observed several oil stains on the surface and collected three soil samples the same date of the site survey. Lab analytical results detected total recoverable petroleum hydrocarbons (TRPH) at concentrations up to 41,000 mg/kg and total petroleum hydrocarbons as diesel at concentrations up to 13,000 mg/kg. Benzene and other petroleum hydrocarbon constituents that would have classified this material as a hazardous waste were below concentrations that would have classified them as hazardous. I also observed ACM in two locations on the property. Several small (<3" diameter) pieces of asbestos were found on the surface near the boat ramp on the east side of the property and a small pile of pipes that are wrapped in asbestos were located beneath a tarp behind an old excavator on the south side of the property. Lab analytical results found that the asbestos is friable and contains more than 1% asbestos. Based on these results, the ACM must be handled and disposed of as non-RCRA hazardous waste. There is less than 100 SF of asbestos on the property such that we will not be required to have an ASB certification pursuant to the California Business and Professions Code Section 7058.5 (a). Cook Environmental Services is a licensed contractor (921387 A, HAZ) and is licensed to remove and dispose of oily contaminated soil. Prior to any commencing any remediation fieldwork, I recommend that we notify the San Joaquin County Environmental Health Department (SJCEH) of our intention to clean up the site and enlist their involvement. In all likelihood, the SJCEH will require a work plan describing our approach and procedures to remove the wastes. They will also want to see existing lab reports and our suggested cleanup levels. The County will review, comment on and approve the work plan or request changes. They will also require submittal of a summary report upon completion of the cleanup. 14E15 TREAT BLVD. , STE. 203A • WALNUT CREEK, CA 94597 • P: (925) 478-8390 • F: (925) 478-8394 • VVVVVV.COOKENVIRONMENTAL.00
