NEW YORK SOLID WASTE CONFERENCE Lake George, NY May 5, 2008 to edit Master title style Click Eco-Line Landfill Gas Energy Project TURNKEY RECYCLING & ENVIRONMENTAL ENTERPRISES (TREE) TURNKEY RECYCLING & ENVIRONMENTAL ENTERPRISES • Owned by Waste Management, Inc. • State-of-the-art ECO-Park located on 1300 acres in Seacoast Area of Southern New Hampshire. • Park includes three double lined landfills, 2 power plants, 5 flares, MRF, Collection Company, Citizen Drop-off, and Leachate Pre- treatment Plant. • Site is certified Wildlife Habitat Area under the Wildlife Habitat Council. • Recreational and Community Projects on site include: a homeless shelter, golf range, hiking trails, canoe launch, model airplane field and a park. New Hampshire Locus Map Facility TREEFacility TREE Facility TREE Rochester, NH TREE Facility TREE Facility TREE Facility Rochester, NH TREE Facility Rochester, NH Rochester, NH Rochester, NH TREE Rochester, NH Facility Rochest TREE Facility er, NH Rochester, NH Project Background • Long standing relationship between WM and UNH. • WMNH/TREE currently has two LFG to Electricity plants producing 9 megawatts of power. Waste Management has over 100 landfill gas to energy projects nationwide, and will build 60 more in the next 5 years. • Site is currently using approximately 4000 scfm of LFG and producing over 8000. • WM approached UNH regarding project concept. • Contract negotiated in 2006/2007. 10 year contract with options for renewal up to 7000 scfm of gas is committed to UNH if available above site power plant demands. TREE Gas Recovery Plant 1 Project Details • 12.7 mile, 12 inch HDPE pipeline travels along public roads, turnpike, and private rail right of way. • Processing plant located at landfill will remove CO2, H2S, and Siloxanes. Minimum methane content required is aprox. 82 %. • Two 3520 CAT engines will provide parasitic load for processing plant, site gas blowers, and site leachate pump station. • Plant will be designed, constructed, and operated by SCS Energy as contractor for UNH.

Current Project Status • Pipeline was completed last Fall/Winter, by RH White. • Directional drilling was used to minimize wetland disturbances. • UNH was able to fast track permitting through state agencies and is exempt from local permitting. • Processing plant construction will begin this month with completion scheduled for Jan, 2009. • Turnkey has over 300 gas wells and over 200 of them have dedicated pneumatic pumps for dewatering into a separate force main.
