The proposed remedial action,or corrective action remedy for the two areas is to <br /> excavate the soil and transport it to a land fill permitted to accept this type of waste. The two areas to be remediated <br /> consist of: 1)a fuel storage area found to have approximately 10 cubic yards of soil impacted with petroleum <br /> hydrocarbons,and:2)a site adjacent to the former location of a oil storage mak found to have approximately 57 <br /> cubic yards of soil impacted with petroleum hydrocarbons. In total,approximately 67 cubic yards of soil will be <br /> excavated and transported to an appropriate approved disposal site. This is the final step required in the corrective <br /> action process to clean the site to standards appropriate for residential use of property. No further corrective action <br /> will be required for the site. <br /> This site is in a remote area in the Altamont Hills. This is an and area and there are no wetlands in the area. The <br /> area has not been shown to be a cultural resource area. Depth to groundwater is approximately 100 feet and no <br /> impacts to groundwater are expected due to: t)the depth is groundwater is relatively deep:2) the shallow nature of <br /> the soil contamination(5 feet maximum):and 3)and the low mobility of petroleum hydrocarbons through soil. <br /> Name of Public Agency Approving Project: Department of Toxic Substances Control.CALIEPA <br /> Name of Person or Agency Carrying Out Project: General Dynamics OTS(California Inc.), <br /> formerly:Primex Technologies <br /> Exempt Status:Tide 14,Section 15061 (b)(3) <br /> With Certainty No Possibility of a Significant Environmental Effect <br />
