Rev.0,4/22/11 Project 110219 2 PROPOSED PROJECT 2.1 General Ameresco is proposing to construct an LFGTE Facility at FSL to convert collected LFG to electrical power. The LFGTE facility is proposed to be located south of the existing LFG flare at FSL. The LFGTE Facility will produce energy from the LFG generated at FSL using two (2) LFG-fired reciprocating engines. Each engine will be sized to handle a maximum of 704 standard cubic feet per minute (scfm) of LFG and produce approximately 2.18 Megawatts (MW) of electric power. The total plant output for both engines less internal electrical use will be 4.2 MW. The existing LFG flare will continue to be the primary control device for the landfill but will not operate when the LFGTE Facility is operating except to burn excess LFG beyond what the engines can handle. The flare will also provide backup LFG combustion capacity in the event the engines are both off-line. 2.2 Facility Layout out Figure 2-1 is a Vicinity Map which depicts the proposed LFGTE facility in relation to the entire FSL property. The proposed LFGTE Facility will be located directly south of the existing flare in the southeast corner of the property. Figure 2-2 is a Site Plan. An approximately 50-ft by 70-ft building is proposed to house an office, the LFGTE engines, electrical switchgear, and other ancillary equipment. In addition, an outdoor concrete pad area will be located adjacent to the building on which skid-mounted LFG conditioning/treatment equipment, an electrical transformer and an auxiliary flare will be placed. The auxiliary flare is used to combust off gas that is generated during the regeneration cycle of the absorptive media LFG treatment system. Sanitary facilities will be provided in the form of a Wells Cargo Comfort Elite ADAI or similar self-contained restroom facility, which will be serviced on a routine basis. Power will be provided by the LFGTE facility. Potable water needs are limited and will be supplied by existing water wells at the FSL. The LFGTE engine dimensions will be approximately 9.2-ft high, 7.5-ft wide, and 32.5-ft long. The planned stack height for each engine will be 32-ft above ground with a diameter of 20- inches. The off gas flare stack is 4' in diameter and will extend 50-ft above the ground. A schematic illustration of typical LFGTE building elevations is provided as Figure 2-3 and typical facility photographs are provided as Figure 2-4. The building is approximately 24-ft high and will be sited on native ground at an approximate elevation of 230-ft.
