-192- Ramsey Town Center AUAR 6 March 14, 2003 Page 13-7 to 13-8--"In addition, it does not appear that the municipal wells would have any negative influence on private wells developed in the same unit. However, long term monitoring of the surficia! aquifer's water level is recommended so that data can be collected to coordinate against the long term trending patterns within the FIG". We concur with the statement that groundwater level monitoring of the surficial aquifer would provide valuable information regarding trends in the availability of shallow grotmdwater that recharges the deeper aquifer utilized by the City's wells. If it becomes necessary, such wells could be used to test and monitor the quality of the surficial aquifer in the event ora spill other pollution event. Recommendation: 8. Insert discussion considering the installation of surficial monitoring well, s to aid in determining if increased water demand from this development impacts groundwater availability. Selection of monitoring well positions should provide for determining groundwater flow direction. The materials and construction of the monitoring wells should be sufficient to utilize, if necessary, as water quality monitoring wells. Page 13-8---"Within WH?As, the use of conventi°nal underground storage tanks to store anything other than water is restricted. If underground tanks are utilized in these areas they must be double-walled with interstitial sensors and a networks of monitoring wells must be installed to assess potential groundwater contamination" The statement that under=oxound storage tanks (USTs) are restricted within a wellhead protection area may not be accurate. We are not aware of any additional restrictions or requirements for USTs within wellhead protection areas. Recommendations: 9. This statement should provide a reference to State statute, rule, or local ordinance that places this addition restriction on USTs located within a wellhead protection area. If no supporting regulatory documentation is provided this statement should be deleted. 10. That the AUAR acknowledge that USTs may be located in the City's wellhead protection areas and encourage the City to address this potential contaminant source in their wellhead protection plan (under development). Page 20-3 "In order to safeguard and sustain the public water supply, 'wellhead protection areas' (WHPAs) and 'drinking water supply management areas' (DWS~Dis) are delineated aroundpublic water supply wells (Figure 20./). The Ramsey Wellhead Protection Plan was developed [emphasis added] in cooperation with... ". The Ramsey Wellhead Protection Plan is in development. Part 1 on the wellhead protection plan, addressing WI~As, DWSMAs and well vulnerability classifications has been completed and approved by MDH. Part 2 of the City's wellhead protection plan is being developed and will I I I I I I I I I I I I I I I I I' !
