29. Cumulative Impacts <br />This item does not require a response from an AUAR since the entire AUAR process deal <br />with cumulative impacts from related developments within the AUAR area. <br />30. Other Potential Environmental Impacts <br />If applicable, this item should be answered as requested by the EAW form (if the <br />project may cause any adverse environmental impacts not addressed by items 1 to 28, <br />identify and discuss them here, along with any proposed mitigation). <br />There are no additional major adverse environmental impacts beyond those addressed by <br />Items 1-28. There are, however, two minor issues that need to be raised. First, the <br />impacts of the Anoka -Ramsey Landfill on the RTC are presented to alleviate any <br />potential concerns. The landfill is located within one mile of the RTC site in Township <br />32N, Range 25W, Section 22 (Figure 19.5). The RTC is located southwest of the landfill. <br />Regional groundwater flow throughout this part of Ramsey is to the southeast, indicating <br />that pollutants from the landfill are flowing away from the project area. Additionally, the <br />continued mitigation at the landfill has contained the plume horizontally using twelve <br />barrier wells and eight recovery wells. Finally, sampled residential wells screened in the <br />Franconia aquifer have been negative for all monitored contaminants. This means that <br />the potential for contamination of the water supply from the landfill is minimal because <br />the City of Ramsey wells are screened in an aquifer that has not been contaminated and <br />groundwater flow direction is away from the wells (Anoka/Ramsey Landfill SW-094 <br />2000 Annual Report). Because of the location of the RTC, the minimal threat to the <br />water supply and the successful remediation at the landfill, there should not be any <br />adverse environmental impacts. <br />Secondly, the RTC will change land use from agricultural to urban. Although this marks <br />an end to agricultural use of the site, Item 27 described the orderly planning process <br />under which this transition occurred. The mitigation elements summarized in Appendix <br />D address how the lost environmental features of the undeveloped agricultural site will be <br />replaced, and in some cases, improved. <br />29/30-1 <br />
