of capacity at the landfill to steepen existing slopes on the landfill. <br />Maximum slope on the expanded area would be 4:1. In addition to the <br />capacity, vertical expansion inclues a very highly engineered cover <br />system and drainage system. <br /> <br />2) <br /> <br />Borrow Plan - The borrow plan is divided into two areas: east and west. <br />The borrow area is approximately 40 acres in size, 30 of which will be <br />developed as the east borrow area and consisting of 4 phases. Access <br />to the east and west borrow area will be from the landfill property <br />itself. The borrow areas would be excavated to a minimum separation <br />distance from the groundwater of 5 feet. Once the east borrow area is <br />developed, operations will move into the west borrow area, which is <br />much smaller and will be developed in one phase. Operations in the <br />west borrow area will maintain a 200 foot setback from adjacent <br />properties. Operations in the east borrow area will not affect the <br />wetlands. The total amount of material to be removed from the east <br />borrow area is 400,000 yards and 150,000 yards from the east borrow <br />area. <br /> <br />3) <br /> <br />Grade Roadway - The roadway would extend to Sunfish Lake Blvd. and <br />passing through the northern tip of the wetland in the area. The <br />permitting process for the road could possibly result in a change in <br />the road alignment. <br /> <br />Mr. Sivick stated that as part of the vertical expansion project, Waste <br />Mangement agreed to have an environmental impact statement prepared. The <br />document consists of a number of sections and includes that addresses <br />alternatives to the project. The bulk of the document was prepared by MPCA <br />under contract to Metro Council. The geohydrology section deals with <br />remedial action approved by MPCA, final cover, contours, environmental <br />impact associated with the additional waste, potential mitigation of <br />potential impacts identified with the project, air quality. There is also <br />a lengthy discussion of economic impacts related to the project, physical <br />impact, aesthetics, historical and archaeological impacts. <br /> <br />Don Otter stated that if the regulatory agencies reject the ski hill <br />proposal for environmental reasons, Waste Management is prepared to <br />dedicate 50 acres of land to Ramsey for future development in the area. <br />Mr. Otter noted that the economic benefit to Ramsey is estimated at <br />$2,000,000 in royalties over the life of the vertical expansion project; <br />tipping fees are estimated to add up to another $150,000. <br /> <br />Jerry Sivick stated that the liner to be placed under the vertical <br />expansion is a flexible member material that is about 40 mils thick and the <br />permeability associated with it is extremely slow; infiltration will be <br />reduced about 95%; life expectancy of the liner is almost indefinite. <br /> <br />Jerry Sivick stated that the cover capping will be a phased process. <br /> <br />Mr. Otter noted that the north slope of the landfill will be the first area <br />to be completed and will receive final cover in 1990. <br /> <br />Jerry Sivick stated that a test plot has been installed to verify to MPCA <br /> Planning & Zoning Commission Public Hearing/September 8, 1988 <br /> <br />Page 2 of 6 <br /> <br /> <br />
