REYNOSO CONCRETE CONSTRUCTION COMPANY 352 DEER HOLLOW JUN 2 2 199 NAPA CA 94558 RE: Reynoso Concrete Construction Co. SITE CODE: 2556 729 S. Commerce Stockton, CA San Joaquin County Pubic Health Services,Environmental Health Division (PHS/EHD)has reviewed the letter from Falcon Energy Associates dated May 29, 1993 concerning the stockpiled soil at the above referenced site. Although there is continuing discussion concerning the classification of petroleum contaminated soil PHS/EHD requires that this type soil be certified non-hazardous according to the requirements of the California Code of Regulations Title 22 Division 4.5 Article 3 Section 66261.2 prior to off-site transport. Specifically pursuant to guidance provided PHS/EHD from California EPA, Department of Toxic Substance Control in 1989 responsible parties should conduct self certification by performing bioassay testing and waste extraction testing for metals. These tests are also required by landfills prior to their acceptance of petroleum contaminated soils. Until some other guidance is provided by the state agencies PHS/EHD will continue to require the bioassay and metal testing of petroleum contaminated soil prior to transport. The samples collected from this site on April 16, 1993 were from the sidewalls and bottom of the excavation not the stockpiled soil. The samples were analyzed for BTEX, TPH-gas, TPH-diesel and lead. No other metals were analyzed for nor was the bioassay test performed. Thus certification of the soil as non-hazardous was not completed. Please notify PHS/EHD of your plans prior to the disposal or treatment of the stockpiled soil. As the owner of the site you are ultimately liable for the disposition of the soil.
