1.1 Scope

The former Castle AFB is listed on the National Priorities List (NPL) and has a Federal Facility Agreement (FFA) in place. A Preliminary Closeout Report was prepared by the United States Environmental Protection Agency (USEPA) in 2006. Records of Decision (RODs) have been signed for all Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) sites included in this task order and Last Remedy in Place (LRIP) has been achieved for the base.

The 18 sites included in this task order are being addressed following the CERCLA process or state corrective action program (non-CERCLA). There are two CERCLA sites in remedial action-operation (RA-O) and all CERCLA sites require IC monitoring and Five Year Review. Groundwater pump and treat systems are currently operating at these two of the sites (OT029 and OT030). The Operable Unit (OU)-1 Basewide Phase 3 groundwater treatment plant is currently operating at OT029 and the OU-2 groundwater treatment plant (Main Base Plant) is currently operating at OT030. Groundwater contamination associated with former Air Force activities has migrated beyond the former base property boundaries. Seven of the CERCLA sites are associated with three capped landfills/sites with ongoing Long-term Management. One CERCLA site has ICs and requires Five-Year Review only. Eight petroleum-contaminated sites have ICs and require non-CERCLA Five Year Review only.

In addition to the requirements presented in this PWS, this scope includes the following:

· Monitoring for 1,2,3-TCP.

· Replacement of wells that are dry due to lowering groundwater table, as needed.

Contractors are not responsible for the following:

· No additional base-specific exclusions.
