APPENDIX C: PUBLIC COMMENTS

The West Kingston Town Dump and University of Rhode IslandDisposal Area public health assessment was available for publicreview and comment in local libraries for a 30-day period endingNovember 12, 1992. The public comment period was announced inlocal newspapers. In addition, the public health assessment wassent to several individuals or organizations. One set ofcommments was received. Specific comments and responses aresummarized below.

Comment 1:

EPA reported the site was finalized on their National PrioritiesList (Final Rule) in October 1992.

Response:

The public health assessment has been revised.

Comment 2:

USEPA reported that Figure 1 does not seem to accurately depictthe relative areal extent of the two disposal areas; the commentwas later rescinded.

Response:

No revision required.

Comment 3:

USEPA reported they plan to gather data to characterizecontamination at the site and contiguous areas.

Response:

The public health actions section of the public health assessmenthas been augmented to reflect the proposed data gathering.
