SJCPHD-EHD Final ground-water monitoring and well-abandonment tasks have now been <br /> completed, as described in this final Project Status Report by W W Irwin, Inc <br />' The results of the analysis of sample no "Soil Pile A" revealed 156 m /K of TEPH-motor oil <br /> P mg/Kg <br /> (by EPA Modified Method 8015) and 43 mg/Kg of TRPH-oil & grease (by EPA Method 418 1) <br /> A method for disposition of the soil is landfill disposal It would involve costly, manifested, <br /> hazmat-type transport by dump truck to a Class II landfill A treatment, storage, and disposal <br /> (TSD) facility such as Forward, Inc in Manteca will accept the soil at a cost of about $20 00± <br /> 1 per ton <br />' However, project manager Dayne L Frary requests the cooperation of the SJCPHS-EHD in <br /> allowing for on-site spreading and aeration The TEPH-motor oil concentration is dust 156 <br /> mg/Kg, and the soil should aerate well if spread in its present overall location No volatile <br />' components are known in decomposing TEPH-motor oil Therefore, atmospheric impaction <br /> would be negligible If a confirmation sample for TEPH-motor oil analysis is ordered by the <br /> SJCPHS-EHD, it should be collected in July or August At that time, a sample would be <br /> expected to exhibit less than 100 mg/Kg of TEPH-motor oil Then, final closure might be <br /> obtained This plan for soil disposition is by far the least costly of the two options <br /> 1 <br /> I <br /> I <br /> W W Irvin, Inc <br /> Projects 33236 00&33236 01 <br /> Apnl 1996 8 <br />
