a contour map showing the existing condition of the site and a wetland mitigation and impact map showing the proposed restoration of the site; and a proposed Conditional Use Permit (CUP). Issues: Traffic - The gravel mined from the site is proposed to be delivered to the Elk River Bituminous site via easements across private property owned by Schuer, Inc and Aggregate Industries. Peat will be hauled via easements to an existing access point for a Bauerly Bros. mining operation to 225th Avenue and then west to Highway 169. The majority of the peat will be used as topsoil at the Elk River Landfill. Section 10 of the attached CUP has additional stipulations on traffic. Groundwater - Mining into the groundwater raises additional concerns. Matt Ledvina, City Environmental Consultant, addresses these concerns in his attached letter. Environmental Spill Plan The petitioner's Environmental Spill Plan xvill be revised to address Mr. Ledvina's issues, e.g. identifying refueling locations. Ground Water Monitoring Plan The Ground Water Monitoring Plan will be revised to include monitoring for pH, temperature and conductivity as well as Diesel Range Organics. Staff does disagree with Mr. Ledvina regarding monitoring all three wells at the site, however. Staff recommends that only the down gradient well located in the northeast comer on the site be monitored (MW1). Incidents of contamination will be known. Section 17 of the attached CUP has a condition that allows additional wells and additional testing events, if needed. National Pollutant Discharge Elimination System (NPDES) The petitioner has applied to Minnesota Pollution Control Agency for a NPDES permit for the operation. Mr. Ledvina's comments regarding rip rap and a vegetative buffer at the outlet of the ditch on the property will be included as part of the Storm Water Pollution Prevention Plan (SWPPP) required by the city in Section 17 of the attached CUP. Wetlands - The City Council is the Local Unit of Government charged with the final decision regarding the Wetland Conservation Act 0vVCA). The WCA is a separate agenda item for this meeting. The Technical Evaluation Panel, has reviewed wetland issues for compliance with the WCA and is recommending approval of both the wetland impacts and wetland mitigation for the operation. The TEP's recommendation for approval included purchasing excess wetland credit from the Schuer site. Section 9d of the attached CUP requires monitoring of the wetland mitigation, which is to be secured by a letter of credit. A dollar figure to cover the restoration has yet to be determined.
