From: Date: Re~ Steven Rohif, City of Elk River Planning and Zoning Debra Dehn, Elk PJver Landfill Manager Matt Ledvina, ERG 10/16/01 Elk River Landfill - Request to Amend the City of Elk River Conditional Use Permit BACKGROUND. Elk River Landfill (ERL) is requesting to amend Section 2.03, of the current City of Elk River C, onditional Use Permit_ The current Conditional Use Permit was issued in May of 2000 and provided approval of the January 14, 2000 repermit application pacl(~je developed by Wenck Associates. The repem~t application package consisted of an Engineering Report and Plan Sheets, which described the continued development of the landfill utilizing the following updated technology: 1) 3:1 final contour slopes over the remaining undeveloped area; 2) Increased height of remaining undeveloped perimeter berm; 3) Installation of leachate recirculation system; and 4) Surface water drainage and sedimentation improvements (within the buffer zone). The January 14, 2000 Final Contour and Grading Plan as previously submitted and currently approved under the City of Elk River Conditional Use Permit is attached. DESCRIPTION OF REQUEST ERL is requesting to amend Section 2.03 of the existing Conditional Use Permit to provide for development of an additional demolition and construction debris disposal area, known as DC-3, over the top of the previously dosed municipal solid waste (MSW) cell on the west side of the landfill. The development of the DC-3 are~ with a capacity of 620,000 cubic yards, is necessary to provide for immediate disposal of demolition and construction debris. The disposal airspace in the designated demolition and construclJon debris disposal areas, known as DC-1 and DC-2 on the north edge of the facility, has been rapidly consumed over the last few years and these areas are now full. Construction and demolition debris matedal may be placed in the ERL munidpal waste cells, however, this matedal consumes critical MSVV airspace which should be reserved for MSVV. As wel!, when demolition and construction debds is placed in the MSW cell, the haulers are required to collect and pay additional fees on the matedal as if it were MSW. As designers reviewed options for development of the additional demolition and construction debris disposal area, the middle west side of the landfill or the "transition area" came into discussion. This area was previously closed with an MSW cap at 5:1 or 20% sideslopes. Over time, the area has settled, creating sags which hinder proper surface water drainage. At the previously constructed 5:1 slopes, the area was. shown as an odd transition zone sandwiched betv~n the nor,hem demolition area with approved 3:1 slopes, and the southern continued MSW cells also approved for 3:1 slopes. The approved January 2000 plan sheets show the transition area and final contour configuration. · Page I
