The contractor performing the removal cannot sample. Please identify <br />a third party sampling firm. <br />2. Crushing the fiberglass tanks onsite at the time of the removal will <br />require written approval and/or a permit issued by the California State <br />Fire Marshall before this activity can occur. An alternative for crushing <br />the tanks would be to transport the "whole" tanks to an approved <br />receiving facility. <br />3. Any soil proposed to be transported offsite must be hauled as <br />"Hazardous" or self -certified under provisions within Title 22, section <br />66262.11, California Code of Regulations. Sampling procedures will <br />need to be evaluated by PHS-EHD. <br />4. A concrete slab is thought to be under the two UGTs. If this is verified <br />at the removal, soil samples are required from beneath the slab. <br />Soil from under the ends and the center of each removed tank is to <br />have a soil sample collected from no more than four (4') feet below the <br />bottom of the slab ( totaling six samples through the concrete slab). <br />Procedures for boring through the slab are to be submitted for <br />approval. <br />5. All soil samples are to be analyzed for TPH as Kerosene -Jet Fuel <br />(Method 8015m) and for BTEX (Method 8020). Detection limits for <br />TPH are to be 50 mg/kg and 0.005 mg/kg for BTEX. <br />A Division of San Joaquin County Health Care Services (C (a r U <br />
