A schematic illustration of typical LFGTE facility building elevations is provided as Figure 2-3 <br /> and typical facility photographs are provided as Figure 2-4. The building is approximately 24-$ <br /> high and will sit on existing ground at an elevation of approximately 40 feet above mean sea <br /> level (MSL). <br /> 2.3 Facility Construction <br /> The LFGTE facility will take approximately seven months to construct. It is currently planned to <br /> start construction in March of 2012 and be operational in December of 2012. <br /> Prior to construction, a detailed geotechnical report will be prepared. The geotechnical <br /> investigation will evaluate the onsite soils and will provide recommendations for the building <br /> foundation. A seismic assessment will also be performed and recommendations provided. <br /> During construction, approximately 4,000 cubic yards (CY) of excavation will be required in <br /> order to replace the current soil with engineered fill for the building/equipment foundations and <br /> access roads. Fill material will be obtained from onsite excavations. Excess excavated soil not <br /> needed for fill on the site will be used for general landfill operations. <br /> Construction hours are proposed to be consistent with the landfill operation hours. While some <br /> additional traffic will occur during construction, it will mainly be for the occasional delivery of <br /> equipment and the contractor's crew. <br /> Ameresco will work with local utility companies to supply power from the LFGTE engines to <br /> the power grid. The power line connection will occur off of the existing PG&E distribution line <br /> providing electrical service to the flare station. No new electrical transmission line will need to <br /> be added to connect to the power grid, although PG&E will have to upgrade some of their power <br /> lines, poles and equipment to accommodate the project. <br /> 2.4 Facility Operations <br /> Facilityoperations will begin once the LFGTE facilityhas been constructed and all permits have <br /> been obtained. The LFGTE facility is planned to operate 24 hrs/day, 7 days/wk. It will be <br /> staffed by 1 operator who will be at the facility from approximately 8 am to 5 pm. Alarms and <br /> sensors are incorporated within the LFGTE facility to alert the operator of any equipment or <br /> operations issues. Lighting is provided during night time hours using a light stand with <br /> downward shielding to prevent glare. <br /> Maintenance of the LFGTE facility is ongoing; however, the LFGTE facility is periodically <br /> taken offline for major maintenance for 1-3 days. This type of outage is extremely rare as the <br /> plant is designed with backup equipment to allow continued operation during maintenance. A <br /> total plant outage is more typically caused by the utility due to weather related causes or planned <br /> maintenance work requiring the plant to be offline. During these times, the LFG is routed to the <br /> existing LFG flare. <br /> r <br /> C:DocumentsandSettingsyssicasees\DesktopTon dLFGM-Project Description.doc <br /> CORNERSTONE 2-2 LEWIS ENGINEERING <br /> Ea Iraamc-1 G. ap.LLC <br />
