Rev.0,4/22/11 <br /> Project 110219 <br /> ' 2.3 Facility Construction <br /> The LFGTE Facility will take approximately seven months to construct. It is currently planned <br /> to start construction in April of 2012 and be operational in November 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 /> rDuring construction, approximately 6,000 cubic yards (CY) of fill will be required to raise the <br /> existing grade in the area that the plant will be located. The fill will be excavated from existing <br /> soil borrow areas/stockpiles available on the FSL property. <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. As previously indicated, there is no planned imported fill; <br /> therefore all construction traffic from earthwork activities will be contained onsite. <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 likely occur off of the existing electrical service <br /> to the flare station. No new electrical transmission line is currently proposed to be added to <br /> connect to the power grid, although PG&E may have to upgrade some of their equipment to <br /> accommodate the project. <br /> 2.4 Facility Operations <br /> Facility operations will begin once the LFGTE Facility has 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 /> Planned minor maintenance at the facility typically happens once per week and may entail for <br /> example taking one engine offline to change spark plugs or perform an oil change. In these <br /> cases,the operator may have one or two additional persons assisting with the maintenance work. <br /> I.TROJECTS\AN ERESCO\110219-FOOTHILL LFGTE FACRdTY\_ENGINEERMGISan Joaquin County Site Approval Applicauon\FooUtill LFGTE-Project Description(final 4-22-11)Aoc <br /> CORNERSTONE 2-2 LEIS ENGINEERING <br /> E—iroum —1 Group,LLC <br />
