This Corrective Action Plan (CAP) has been prepared to evaluate and select corrective action alternatives to address soil and groundwater contamination at the Building 1065 Area, Presidio of San Francisco, California. This CAP addresses contamination that is related to or co-located with releases of petroleum hydrocarbons from past use of the site. Remedial actions selected will be those that are protective of human health, the environment, and groundwater quality, are cost-effective, allow reuse of the Presidio under the Presidio Trust Management Plan (PTMP), and meet Site Cleanup Requirements (SCRs) under California Regional Water Quality Control Board (RWQCB) Order No. R2-2003-0080 (RWQCB Order).
