APPENDIX E - ATSDR's Response to Comments on the
Petitioned Public Health Assessment
Public Comment Version
GSX Landfill
July 8, 1993
The following responses address technical comments submitted by the public during the public comment period of July 19, 1993 through August 18, 1993. Comments received during the public comment period were logged and became part of the administrative record for the public health assessment. Comments (without indication of who made them) and responses will be included in this appendix to the final public health consultation. Although commenter's names will not be included in the public health assessment, they are subject to Freedom of Information Act requests.
ATSDR does not routinely consider biomedical testing to be a necessary element for its public health assessments. However, the public health assessment is the first step in the public health process. To use a medical analogy, it is the point at which the physician speaks with the patient about symptoms, looks for signs of illness, and reviews the medical record. The physician will then determine if additional actions, like lab tests, are needed.
At this point, there is nothing in the record to verify illness caused by the GSX Landfill. ATSDR's Division of Health Studies agreed to "consider the need for and feasibility of a health study of the community around the site" as more offsite exposure data becomes available. Please refer to the Conclusions section (page 37).
1. The site is presently named the Pinewood Secure Landfill. However, ATSDR will refer to the
site as the "GSX Landfill" because that name was used in previous drafts of this document.
