Title: Proposed Plan / Draft Remedial Action Plan Operable Unit 1 B Installation Restoration Program IRP 3 and IRP 12
Description: The Navy proposes to remediate soil and groundwater contaminated by hazardous substances at Operable Unit (OU) 1B, Sites 3 and 12, which are located on the former Marine Corps Air Station (MCAS) Tustin. The original preferred remedy, described in a Proposed Plan dated April 2002; includes excavation of the contaminated soil, and on-site thermal treatment and reuse of the soil. After the Proposed Plan was presented to the public, additional information was obtained that indicated on-site thermal treatment and reuse of soil is no longer a viable option for soil disposal. This option was determined to be infeasible based on factors related to permitting of an on-site thermal treatment unit, utility connections, and additional treatment requirements. The Navy now proposes to excavate the contaminated soil and dispose of it at an off-site hazardous waste facility.
