The hydrogeologic issues addressed in the EIS have been largely <br />addressed through the Feasibility Study and Remedial Investigation <br />required by the consent order between WM~I and MPCA as well as the <br />Detailed Analysis Report. That process was conducted independently of <br />the vertical expansion issue and ~I will be required to undertake <br />the clean up actions whether the landfill is expanded or not. The <br />City raised concerns at appropriate times over the course of those <br />study periods. Of particular concern, however, is the impact of <br />~q~]~I's proposed ski hill development on the integrity of the final <br />cover. This is particularly important where support apparatus would <br />be installed which may penetrate the synthetic liner. Obviously, the <br />impact of the groundwater recovery and treatment system on the <br />drawdown of the water table and water quality remain concerns. <br /> <br />Leachate <br /> <br />Page 76 indicates that the steeper slopes are projected to decrease <br />the rate of percolation with the proposed final cover by eight to 10 <br />percent over the same cover at currently approved grades. The EIS <br />further indicates "that a net increase in the volume of leachate <br />generated during the implementation of the vertical expansion will <br />occur". This hardly seems prudent when compared to other <br />alternatives. The EIS indicates that the planned flow barrier system <br />should take care of these volumes with a lifetime net reduction. <br /> <br />The proposer, according to the EIS, is looking at a schedule for <br />placing final cover as the site is brought to proposed grades. The <br />EIS further indicates that the cover placement will take two years and <br />be completed in !991 and concludes "Therefore, the length of time to <br />complete final cover placement may not be extended by implementation <br />of the vertical expansion." <br /> <br />This can only be true if the expansion and capacity limits are time <br />restricted as well as volume perr.~itted. Concurrent with this <br />process, ~q~f-.i is seeking a CUP from Ramsey. ~.~L~_~I through that mrocess <br />is not indicating an expansion period of 2.5 years but has indicated <br />that they need a maximum of five },ears. <br /> <br />.... a ........ =_ ..... ~ .... also contribute to teachate p-osu~lon- ' "'' as <br />'~'=~-__~ as create o~--he_~ a~verse in~ac~s on the Cor~unity's development <br />s ....... e and extend nme burden of an operating landfill on residents <br /> <br /> <br />
