The public comment period was announced in local newspapers. Copies of the preliminary public health assessment were made available for review at the public libraries in Hawesville, Kentucky, and in Tell City, Indiana. In addition, the preliminary public health assessment was sent to more than 12 individuals or organizations. Comments were received from two individuals, and the U.S. Environmental Protection Agency (EPA). A summary of those comments along with our responses are presented in this section. The body of the document has been revised where appropriate. The second to the last sentence of paragraph 2 of the Summary section implies that the NSA site contaminated the drinking water supplies of these cities and clearly affirms that residents were exposed to site-related contaminants. However, the EPA does not have any information or evidence to conclude that the site has contaminated any municipal water supply. Information in the summary and other sections indicate that residents were exposed to various contaminants in municipal drinking water at levels below public health concern. In addition, the last sentence of the second paragraph concludes that the sources of contaminants in the drinking water cannot be defined. Therefore, the document has not been changed. The second paragraph (Page 1, first sentence of the second paragraph of the Summary section) also contains a discussion of on-site workers being exposed to fluoride through incidental soil ingestion "at levels that could cause adverse health effects." This discussion does not mention the limited areas on site that an exposure could occur or the previous remedial efforts undertaken by NSA to reduce the fluoride concentrations in surface soils or near impoundments. The summary should mention that upon completion of the Remedial Investigation (RI), the EPA will conduct a Baseline Risk Assessment to quantify (estimate) the human health risks posed by the contaminants found at the site. The second to the last sentence on page 2 of the Summary section states that if additional data and information become available, ATSDR will reevaluate the site for any indicated followup. In addition, the Public Health Action Plan (PHAP), and the Summary have been changed to identify the RI and EPA's forthcoming risk assessment work.

COMMENT: Two people wrote that they attended the public meeting called by the Environmental Protection Agency (EPA) on January 19, 1993, where they and some other residents raised concerns about the safety of eating beef from livestock grazed on vegetation, and produce grown near the site. Other concerns included safety of the drinking water, and of living in the area. One of the people further wrote that her husband, the only resident who attended the ATSDR availability sessions had reported his family's health problems to the ATSDR official at that meeting but no reference was made to the family's health problem in the preliminary public health assessment.
Response: The initial release of the preliminary public health assessment was issued prior to the EPA meeting and could not reflect information from that meeting. In addition, the only resident who attended the ATSDR availability session on December 11, 1991, said that he did not feel that he was endangered by the site but wondered whether he was. He said his family lived in the area for since 1979. He also wondered whether his wife's multiple sclerosis is site-related. ATSDR has identified that issue as a community concern and addressed it in the final document. The resident also asked about another health issue that by its nature was initiated prior to moving to the area. Thus, that ailment is not addressed in the document.

COMMENT:
Response: The first sentence in paragraph 2 of the Summary section states that only those on-site workers such as maintenance, construction, or remedial workers who are, or have been in the past, in close contact with surface soil and other workers at the waste areas were probably exposed to fluoride through incidental ingestion. ATSDR has no information about NSA remediation efforts that specifically identifies the extent to which fluoride concentrations may have been reduced over time in surface soils or near impoundments. Thus, we cannot address that issue in the summary or elsewhere in the document. ATSDR has acknowledged in the Background section of the document that some waste ponds have been closed, but some were opened to replace those that were closed, and some of the latter are not closed. ATSDR has described excavation and temporary storage of soils containing PCBs; those are to be disposed off site. The only other soil remediation of which ATSDR is aware occurred around the spent potliner storage pad where several hundred tons of soil were removed and disposed of off site at approved landfills. ATSDR has seen cyanide data for the excavated soils but is not aware of any fluoride analyses for those materials (33). Therefore, the document has not been changed.
