Center development and the future park development, particularly where the two projects will interface e.g. lighting, site furnishings, landscaping, etc. Response: The comment is acknowledged, and discussions on this have begun between the City and the RTC design team. Comment 8.17: With the discussion of the City's water supply system and potential contaminant sources, this section should include discussion of the vulnerability of the City's wells and wellhead protection areas. The Minnesota Department of Health has determined that Ramsey wells 1 and 2 are not vulnerable to contamination and wells 3 and 4 are vulnerable to contamination. A formal well vulnerability assessment has not been completed for Well 5. We believe that Ramsey well 5 will also be classified as vulnerable to contamination. When the 10-year time of travel capture zone is determined for well 5 we believe that the wellhead protection area will be extended to the south. Response: The Wellhead Protection section of Item 13 and page 19-2 of the document has been changed to reflect the comment. Comment 8.18: It is our opinion that the AUAR has not provided adequate emphasis on the fact that this site is located within a City wellhead protection area. That the City is in the process of preparing and implementing a plan to protect the immediate groundwater resources (10 year time of travel capture zone) used for the municipal drinking water supply. And, that the wellhead protection plan must address potential contaminant sources because the FIG wells are determined to be vulnerable to surface spills and leaks. Recommendations (of the commenter): 1. Discussion of the well vulnerability and wellhead protection area vulnerability should be included in this section and its impact on development of the site. However, this section should not preempt the wellhead protection planning or program activities of the City by addressing potential contaminant sources as a means to protect the City's water supply wells. 2. The AUAR should determine whether additional municipal wells are planned for the site. If additional wells are planned on, or near, the site the AUAR should address this. 3. The AUAR should discuss the timeline and necessity of determining the vulnerability of Ramsey well 5 and its potential impact on development within this site. Response: Changes have been made in Items 13, 19 and 20 to reflect these comments. Reference is made to Appendix F, where future appropriations are also addressed. The City's planned update of its water supply plan will address the location and timing of new facilities associated with the RTC site. Comment 8.19: The AUAR does not accurately summarize information on the geologic hazards and soil conditions in Item 19. The shallow water table, non -continuous clay 34-16
