· current water sources and service area description procedure for augmenting supplies demand reduction procedures ,, procedures for water allocation · establishment of triggers for implementing plan components · enforcement · water supply protection As part of its next revision, the City of Ramsey will amend its t999 Water Supply Plan to include an emergency response element. The amendment will include ail of the above components. This will occur prior to applying for a DNR appropriation permit amendment, which would likely trigger the DNR request for emergency plan completion, as well. Use of underground storage tanks within the WHPA should be discouraged. If underground storage tanks are used to store anything other than watei- within the WHPA, the tanks must be double-walled and the groundwater around the tank must be appropriately monitored for contamination. The development Of a contingency Plan as discussed previously should address the management and procedures that would be : implemented in the case of a leaky tank. ' · Infiltration practices within the WHPAs will be carefully controlled to prevent any water that has not been pre-treated from entering. Rain barrels, grading, and other on-lot best management practices should be utilized in these areas as long as the infiltration 'of street, parking lot, or industrial runoff does not occur with/n the WHPA. Implementation of community education programs for residential and business contaminant sources, such as fertilizers and hazardous household products, will reduce the risk of groundwater contamination from these sources. The installation of monitoring wells throughout the Wt-tPA would be appropriate to protect the water quality of the upper aquifer. Should'contamination occur, a networi~ of monitoring wells would help to quickly identify the contaminant source and aid in the quick remediation and possibly reduce the extent of contamination. A monitoring well network would also help to understand the relationship between the pumping in the Franconia-Ironton-Galesville aquifer and the upper aquifer. The extent of.any further monitoring will be determined during wellhead protection plan development and State water appropriation permitting. Item 21 Mitigation Element. Analysis of the intersection operations indicates that lane additions and installation of intersection channelization and traffic signals would be adequate to mitigate the project impacts at the intersections in the study area. The following roadway widenings are suggested: · Ramsey Boulevard--widen to five lane cross section south of Industry Avenue to provide two through lanes in each direction and a left turn lane/center median D-18- 252
