Shoreline Area Feasibility Study/Remedial Action Plan (FS/RAP)
• Draft FS/RAP evaluates cleanup options and identifies a proposed plan to address soil impacts and naturally occurring asbestos (NOA)
• Cleanup options evaluated using established criteria, including:
› Overall protection of human health and the environment
› Long term effectiveness
› Ease of implementability
• Draft FS/RAP submitted to DTSC for review
• Public comment will open in Nov. 2014
A draft FS/RAP for PG&E Hunters Point Site Shoreline Area has been submitted to DTSC for review

Shoreline Area Cleanup Options
CLEANUP OPTIONS EVALUATED
No Action
Leaving the Shoreline Area “as is” (required by DTSC for comparison purposes)
Soil Removal, Backfill and Shoreline Surface Restoration
Removing shallow impacted soil in the six impacted areas and backfilling where needed. Shoreline restoration will provide long-term protection against NOA.
Soil Containment, Removal, Backfill and Shoreline Surface Restoration
Containing (by covering) impacted soil in two areas and removing shallow impacted soil in the other four areas and backfilling where needed. Shoreline restoration will provide long-term protection against NOA.
