The Navy is responsible for investigating soil, groundwater and soil gas and remediating soil contamination at IR Site 32 resulting from historical activities at Alameda Point (i.e. former NAS Alameda) (Figure 1). Site investigations for IR Site 32 were completed according to the require-ments of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

This Proposed Plan presents the alternatives for site cleanup at IR Site 32. It summarizes the site history, investigations, and remedial alternatives, and explains the basis for choosing the preferred remedial alternative. The Navy, in consultation with the EPA, Regional Water Board, and DTSC will select a final cleanup action for the site in the Record of Decision (ROD) after all information submitted during the public comment period has been reviewed and considered.

The public comment period will be from April 14, 2018 to May 13, 2018. This public comment period allows the public to review and comment on the Navy’s Proposed Plan via mail or e-mail. A public meeting will be held at 6:00 p.m. on April 25, 2018. Members of the public may also submit written and oral comments at the public meeting. The Navy may modify the Proposed Plan or select another cleanup plan based on new information or public comments. The community is encouraged to review and comment on all of the alternatives by May 13, 2018.

The Navy proposes the following cleanup actions to address soil contamination at IR Site 32:
➢ Construction of a soil cover typically 3 feet thick.
➢ Implementing long-term Institutional Controls (ICs) across the entirety of IR Site 32 to ensure public safety and environmental protection.
➢ Construction of wetlands to be used for mitigation of impacted areas.
