APPENDIX 4 - SUMMARY OF PUBLIC COMMENTS AND RESPONSES

APPENDIX 4 - SUMMARY OF PUBLIC COMMENTS AND RESPONSES

This responsiveness summary was prepared to address the public's comments and questions on the Village of Endicott Wellfield draft Public Health Assessment Addendum. The public was invited to review this document during the public comment period which ran from March 3, 1993 to April 9, 1993. Responses were received by the New York State Department of Health and some comments were consolidated or grouped together to incorporate similar concerns raised by more than one person. If you have any questions about this responsiveness summary, contact the Health Liaison Program at the toll-free number 1-800-458-1158, extension 402.

COMMENTS RECEIVED FROM THE PUBLIC

Comment #1

Page 5, Item 2. "Storm water overflow pit". This is a catch basin to collect surface drainage, not an overflow pit.

Response #1

NYS DOH has revised the wording to use the term "catch basin" for collection of surface drainage.

Comment #2

Page 8 and Page 28 "air stripper is effective". We don't know this yet. We have not done performance testing because there are not contaminants in the Ranney Well.

Response #2

The text has been reworded to reflect that past remedial measures are effectively removing VOCs from the municipal water supply.

Comment #3

Page 9 - Access to Ranney Well is restricted, fenced and locked.

Response #3

As discussed in subsection B (site visit) of the Background section of this document, NYS DOH personnel visited the site on June 8, 1992. The Ranney Well pumphouse building was locked and no one can easily interfer with the air stripping units. However, there are two openings in the fence around the wellhead area which people can enter. This discussion has been clarified in the text.

Comment #4

Page 9 - The landfill is NOT being used for disposal of sewer sludge.

Response #4

The text has been revised to reflect past disposal of sewage sludge.

Comment #5

Page 18 - The plywood sheets over the one foot deep holes are valve locations for the golf course water system.

Response #5

This information has been incorporated into the text.

Comment #6

Many of the recommendations are done; many are inconsistent with the ROD issued by EPA; and some, such as controlling flooding of the landfill are ridiculous.

Response #6

Recommendations developed during the health assessment process for a site are not necessarily the same as the recommendations in a Record of Decision (ROD). This difference exists because the ROD identifies engineering measures to clean-up the wastes (i.e., contaminants) at the site, whereas a health assessment identifies measures to protect public health, including appropriate follow-up public health actions. Because preparing a health assessment is an iterative process, some recommendations may be implemented before the health assessment is finalized; other recommendations may no longer be applicable because site conditions have changed. The Recommendations and Background sections in this public health assessment addendum have been revised to reflect actions that were completed during the public health assessment process.

COMMENTS RECEIVED FROM IBM CORPORATION

Comment #1

Page 2 - The second full paragraph should mention that the purge well is also effective in removing VOCs from the groundwater and drinking water supply.

Response #1

The text has been revised to reflect that past remedial measures are effectively removing VOCs from the municipal water supply.

Comment #2

Page 4, first paragraph - Reference to the IBM facility and the spill in 1979 is not appropriate. The IBM site, located 2.5 miles from the Wellfield, is not linked with contamination at the wellfield. It is requested that this paragraph be deleted from the report.

Response #2

This paragraph has been deleted from the text.

Comment #3

Page 5, first paragraph - The correct size of the landfill is 70 acres, not 30 acres. Also, it is our understanding that access to the landfill is currently controlled by means of a gate.

Response #3

Information about the size of the Endicott Village Landfill (Landfill 1) varies. The July 1987 Remedial Investigation Report lists the size of Landfill 1 as 35 acres. The December 1987 Registry of Inactive Hazardous Waste Disposal Sites reports the Endicott Village Landfill to be 20 acres. The Village of Endicott, Department of Public Works, recently reported that the area of Landfill 1 is 50 acres. The text has been revised to reflect that reports about the size of Landfill 1 vary and that the most recent information suggests that the landfill is about 50 acres. As discussed in the Background section (subsection B, "Site Visit"), there is a locked gate across the roadway entrance to the landfill with a posted "No Trespassing" sign. At the time of the site visit, the landfill was not fenced and could be accessed from Industrial Park Drive either vehicles or pedestrians.

Comment #4

Page 6, first paragraph - The discussion regarding the tannery sewer is incorrect. Section 4.1.4 of the Interim RI Report (August 1990) describes the tannery sewer in detail.

Response #4

Information from the August 1990 Interim Report about the Tannery Sewer has been incorporated into the Background section of this public health assessment addendum.

Comment #5

Page 7, fourth paragraph; page 21, bottom paragraph; and page 22, top paragraph - The discussions imply that flooding of the landfill from the Susquehanna River is the cause of contaminant leaching. This is not accurate, since the RI report (February 1992) also attributes leaching to natural groundwater fluctuations in the area and precipitation.

Response #5

Although the Pathway Analyses section (subsection A, Completed Exposure Pathways) also mentioned pumping, the paragraphs were not clear and have been revised.

Comment #6

Page 7, last paragraph - Only the supplemental purge well was part of the interim ROD.

Response #6

The text has been corrected.

Comment #7

Page 8, first full paragraph - It should also be mentioned here that the existing purge well is effective in the control of VOCs.

Response #7

The text has been revised to reflect that past remedial measures are effectively removing VOCs from the municipal water supply.

Comment #8

Page 13, last paragraph - A seep from landfill #2 was also sampled during the RI.

Response #8

Information about sampling of the leachate seep at Landfill 2 has been incorporated into the "off-site contamination" section.

Comment #9

Page 15, third paragraph and page 17, first paragraph - Summaries of the soil gas data were submitted to NYS DEC. Stating that the data were not available is not accurate.

Response #9

The soil gas data for Landfills 1, 2 and 3 have been incorporated into this Public Health Assessment Addendum (Environmental Contamination and Other Hazards, subsection A, On-Site Contamination).

Comment #10

Page 15, last paragraph - This statement is not accurate in that a total of nearly 60 samples were analyzed from 16 soil borings and 6 test pits during the RI.

Response #10

Information about subsurface soil sampling data from Phase I of the Supplemental Remedial Investigation as well as test pit sampling has been incorporated into this public health assessment addendum.

Comment #11

Page 19, 2nd paragraph - IBM Endicott submits TRI data in July of each year for the previous calendar year to both the US EPA and NYS DEC. The data from 1991 was submitted in July 1992 and, therefore, was available to NYS DOH via the NYS DEC. To state that the 1990 data is "the most recent data submitted by industrial facilities" is not accurate. In addition, reference to off-site facilities appear counter productive with the objective of the study, namely to evaluate the Endicott Wellfield site risks.

Response #11

At the time when this Public Health Assessment Addendum was first prepared in early 1992, the most recent Toxic Chemical Release Inventory (TRI) data available for use in this evaluation was for the calendar year 1990. The text has been revised to reflect the calendar year (1990) for which TRI data were used.

A significant portion of the health assessment process involves identifying the contaminants of concern at a site. The March 1992 ATSDR Public Health Assessment Guidance Manual identifies the TRI as a source of information that must be examined when identifying contaminants of concern at a site. As discussed under subsection E (Toxic Chemical Release Inventory), NYS DOH is using 1990 air emissions data reported to the TRI as a means to evaluate other sources of additional health risk in the population exposed to contaminants from the Endicott Village Wellfield site. However, we have forwarded your comments about including TRI data as part of the health assessment to ATSDR.

Comment #12

Page 22, top paragraph - The use of term "improperly buried industrial wastes" is questioned here. "Improper disposal" would imply that there was a "proper" means (i.e., RCRA) of disposal during the relevant time period.

Response #12

The term "improper" has been deleted from the text.

Comment #13

Page 22, fourth paragraph - VOC's have not been found in the sediments at the golf course.

Response #13

Information about sediment sampling activities and data from Phase I of the Supplemental Remedial Investigation (as presented in the 1990 Interim Report) have been included in the text. These data show that acetone was the only volatile organic compound (VOC) detected in only one sample from the golf course pond at 16 micrograms per kilogram. In the SRI, the acetone in this sample was suspect as acetone was not detected in other samples or during subsequent sampling.

Comment #14

Page 24, first paragraph - The statement regarding a "moderate increased risk of developed cancer" is highly speculative and inflammatory. The "estimate" is based on 2 extreme assumptions, namely, an individual drinking contaminated water for 25 years and that the level of contamination was at 10 mcg/L of vinyl chloride (the highest concentration ever measured). There is no discussion regarding vinyl chloride being a breakdown compound of other chemicals and it may have taken many years to form. Also, since 10 mcg/L is the highest level ever measured, it would be more realistic to assume that levels began at 0 mcg/L and increased to 10 mcg/L over a period of time. Finally, since vinyl chloride has been within drinking water standards for a number of years now, it would be more beneficial to the reader if that fact were stated and if a time period (i.e., '68 - '83) could be assigned to the NYS DOH assumed risk period.

Response #14

Contamination of the Endicott public water supply was first detected in 1981 and aeration treatment to remove volatile organic contaminants (VOCs), including vinyl chloride, was started in 1983. Prior to 1981, it is not known how long or at what levels users of the Endicott Wellfield were exposed to contaminants in their drinking water. The source of VOCs in the Endicott public water supply has been identified as the Endicott Village Landfill, which began operation in the late 1950's. Thus, the water supply could have been contaminated for no longer than about 25 years (late 1950's to 1983).

The estimated increased cancer risk for exposure to the highest level of vinyl chloride detected (10 mcg/L) is moderate (greater than one in ten thousand) for exposure periods greater than about six years. The levels of vinyl chloride contamination in the public water supply prior to 1981 are not known and could have been less or greater than 10 mcg/L.

The Public Health Assessment Addendum for the Endicott Wellfield/Ranney Well has been revised to provide information on the exposure period, the selection of an exposure concentration for vinyl chloride as well as a discussion of the occurrence of vinyl chloride in groundwater.

Comment #15

Page 29, Conclusion #8 - Should discuss the issue of groundwater fluctuations and precipitation as mentioned in previous comments.

Response #15

This conclusion has been modified to reflect other factors which may have contributed to contamination of groundwater at the Endicott Wellfield.

Comment #16

Page 29, Recommendation #6 - Investigations and corrective measures of groundwater contamination have been conducted at the IBM Endicott facility since 1979 under the direction of the NYS DEC. The studies have shown that groundwater beneath the IBM facility has not contributed to the Endicott Wellfield contamination. In fact, other Village wells (South Street) downgradient and much closer to the IBM facility have not been impacted. Therefore, this recommendation is not necessary and it is requested that it be removed.

Response #16

This recommendation has been eliminated.

Comment #17

Page 30, Recommendation #10 - Wells were installed north and west of the Endicott Landfill during the supplemental remedial investigation. It has already been concluded that there is no contaminant impact to the Ranney Well from this area.

Response #17

This recommendation has been removed.

Comment #18

Page 30, Recommendation #11 - Additional control measures were evaluated resulting in the supplemental purge well. Other controls such as slurry walls, cut off trenches, sheet piling, etc. would be ineffective given the high permeability of aquifer, lack of landfill liner and hydrogeologic setting.

Response #18

This recommendation was initially presented in the Draft Public Health Assessment Addendum to ensure that additional measures to control migration of contaminated groundwater from the Endicott Village Landfill to the Endicott Wellfield would be considered to address NYS DOH public health concerns. Installation of the supplemental purge well was completed in November 1992 and operation of this supplemental purge well began in September 1993. The Background section (subsection A, Site Description and History) has been revised to reflect current conditions and this recommendation has been eliminated.

Comment #19

Page 30, Recommendation #12 - As previously referenced, there are several other mechanisms by which contaminants are released to the groundwater. Additionally, concerns about increased flooding upstream and unacceptable construction given the adjacent Tri-Cities Airport would need to be addressed.

Response #19

As discussed in NYS DOH's response to previous comments in this responsiveness summary, other factors which may have also contributed to contamination of groundwater at the Endicott Wellfield are discussed in the Pathways Analyses section (subsection A, Completed Exposure Pathways) of this document. This recommendation has been eliminated.

Comment #20

Page 30, Recommendation #15 - The drummed wastes present no unacceptable risk, therefore, they can be removed (or covered) during site remediation (capping).

Response #20

The recommendation to remove drummed wastes from Landfill 1 is based upon the potential physical hazard that drummed wastes and open drums at the landfill surface pose to trespassers. Since the physical condition and integrity of these drums can change, these drums pose a potential physical hazard to trespassers at the site. As the landfill is not fenced, pedestrians can easily access the landfill from along Industrial Park Drive.

Comment #21

Pages 34 to 38 - The list of references does not include many relevant documents relating to the Endicott Wellfield that have been developed over the past two to three years. These documents are the Interim Report (August 1990); Remedial Investigation Report (February 1992); Feasibility Study Report (July 1992); Addenda to the Feasibility Study Report (August 1992); US EPA Risk Assessment Report (June 1992); Environmental Review Report (June 1992). Due to the lack of reference to these documents, it can be concluded that they were not used in the preparation of the NYS DOH report. It is our opinion that the NYS DOH report is essentially incomplete without reference to the information and recommendations/conclusions contained in these reports.

Response #21

Because of the volume of documents, correspondence and other site-related information which NYS DOH reviewed for preparation of this Public Health Assessment Addendum, a single reference to the NYS DOH project files for this site was provided as a reference. The reference list for this public health assessment addendum has been revised to include those reports that were specifically referenced during preparation and updating of this document.
