Emergency Remediation 2480 Tracy Blvd., Tracy, CA. • Page 5 SOIL TREATMENT Given its estimated volume, to permit construction to proceed it is expected that the soil affected by gasoline temporally stockpiled on the 2480 Tracy Blvd. site will have to be hauled to the landowner's nearby property at 11th Street and Grant Line Road for treatment. Subject to approval by the SJCPHS and, as necessary, the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD) the affected soil will be re-stockpiled at the treatment site and then progressively spread for treatment at the rates permitted by SJVUAPCD regulations. After spreading, the soil will be periodically rototilled to accelerate aeration of components of gasoline The spread and treated soil will be periodically sampled according to a statistically-valid, soil-sampling plan that will be prepared by a California-licensed geotechnical engineer. Soils will be treated until the concentrations of TPH as gasoline, benzene, toluene, ethylbenzene and total xylene isomers and ethyl benzene are no longer detectable. When the clean up standard has been achieved, the soils will be remain in place at the treatment site. (Note: If the volume of hydrocarbon soil that has to be excavated is significantly less that estimated, or vacant land adjacent to the subject site can be made available to provide sufficient room to spread the soil for treatment, it may be treated at the subject property by the same process that has been described above.) HEALTH AND SAFETY PLAN Work for the emergency remediation will be subject to the site-specific health and safety plan presented in Appendix A REPORTING At the conclusion of the project, a report will be prepared under the direction of a California-licensed professional engineer to document the emergency remediation work performed and to compile and record all laboratory tests and other pertinent data obtained. during the progress of the work The report will be submitted to the SJCPHS and any other concerned regulatory authority.
