of capacity at the landfill to steepen existing slopes on the landfill. Maximum slope on the expanded area would be 4:1. In addition to the capacity, vertical expansion inclues a very highly engineered cover system and drainage system. Borrow Plan - The borrow plan is divided into two areas: east and west. The borrow area is approximately 40 ceres in size, 30 of whioh will be developed as the east borrow area and consisting of 4 phases. Access to the east and west borrow area will be from the landfill property itself. The borrow areas would be excavated to a minimum separation distance from the groundwater of 5 feet. Once the east borrow area is developed, operations will move into the west borrow area, which is much smaller and will be developed in one phase. Operations in the west borrow area will maintain a 200 foot setback from adjacent propertiea. Operations in the east borrow area will not affeot the wetlands. The total amount of material to be removed from the east borrow area is 400,000 yards and 150,000 yards from the east borrow trade Roadway - The roadway would extend to Sunfish Lake Blvd. and passing through the northern tip of the wetland in the area. The permitting process for the road could possibly result in a change in the road alignment. Mr. Sivick stated that as part of the vertical expansion project, Waste ¥~ngement agreed to have an environmental impact statement prepared. The document consists of a number of sections and includes that addresses alternatives to the project. The bulk of the document was prepared by MPCA under contract to Metro Council. The geohydrology section deals with remedial action approved by MPCA, final cover, contours, environmental impact associated with the additional waste, potential mitigation of potential impacts identified with the project, air quality. There is also a lengthy discussion of economic impacts related to the project, physical impact, aesthetics, historical and archaeological impacts. Don Otter stated that if the regulatory agencies reject the ski hill proposal for environmental reasons, Waste Management is prepared to dedicate 50 acres of land to ~amsey for future development in the area. Mr. Otter noted that the economic benefit to Ramsey is estimated at $2,000,000 in royalties ~,er :he life of the vertical expansion project; tipping fees are estimated to add up to another $150,000. Jerry $ivick stated that the iimer to be placed under the vertical e;:pa~sion is a flexible member material that is about 40 mils thick and the permeability associated with i: is extremely slow; infiltration will be reduced about 95%; life expectancy of the liner is almost indefinite. Jerry $ivick stated that the cover capping will be a phased process. Mr. 0tier mo:ed that the north slope of the landfill will be the first area :o be c c~-p!e:ed and will receive final cover in 1990.
