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