15. Comment: Figure 3-3, Residential Tier 2 H-SSTLs Include sample points in marsh area that exceeded Residential Tier 2 H-SSTLs for general reference. This will assist in evaluating future land uses for the site and potential exposure concerns for nearby residents.

Response: The future land use of the marsh is not expected to be residential. The marsh is currently being used for research and teaching purposes, and is the home of the endangered Clapper Rail. Therefore, we believe that it is not necessary to apply residential levels to the marsh.

Note: no sample points in the marsh were agreed to in response to potential exposure concerns for nearby residents.
