This work will be scheduled in the spring to mini - <br /> mize the complications due to rain . Soils within the saturated <br /> zone will not be removed . Excavated soils will be screened for <br /> the presence of gasoline hydrocarbons using a photoionization <br /> detector ( PID ) calibrated to an isobutylene standard . Four wall <br /> and two oor confirmation samples will be collected in accord - <br /> ance with WaterWork Protocols ( Attachment 1 ) . Soil samples will <br /> be analyzed for BTEX , TPHG and TPHD by EPA method 8020 and 8015 . <br /> Excavated soils will be stockpiled on- site , placed on and covered <br /> with 6 mil plastic sheeting . Contaminated soil will be aerated <br /> on - site under permit from the San Joaquin County Air Pollution <br /> Control District ( air board ) . Composite samples will be <br /> collected from the excavated material as required by the air <br /> board for processing of the aeration permit . Treated soils will <br /> be backfilled into the excavation or incorporated into the re - <br /> sorts grounds . If additional clean backfill is required , it will <br /> be imported from a reputable source . During backfills the soils <br /> will be compacted and brought up to grade . Successful treatment <br /> will be verified by sampling in accordance with County regula - <br /> tions . <br /> 1710 MAIN STREET • ESCALON, CA 95320 • (209) 838-3507 <br /> 2350-A WALSH AVENUE • SANTA CLARA, CA 95051 (408) 496- 1249 <br />
