Section 2 I Experience/Background <br />• Reconfigured the cell orientation to allow for more efficient development and waste placement; <br />• Lowered cell base grades and increased slide slope grades to increase disposal capacity; <br />• Simplified leachate collection by locating all low points on one side of the landfill and reducing the <br />number of sumps; <br />• Established a long-term layout for leachate and LFG management for both the unlined (dual phase <br />wells) and lined areas (leachate collection and horizontal gas extraction wells); <br />• Justified a vertical expansion over the unlined portion of the Landfill; and <br />• Calculated applicable closure and post -closure care costs to establish financial assurance funding. <br />This information was then used to establish future capital improvement plans and the necessary tipping <br />fee schedule to account for revenue streams and construction/operating expenses. This planning effort <br />extended the life of the landfill, improved operation and development efficiency, and improved <br />environmental protection. As you look at the Sioux Falls Landfill today, the magnitude of this Plari s <br />success is evident. All elements of the Master Plan have been implemented and the City solid waste <br />program is financially viable. <br />Construction and Demolition Material Recovery <br />Facility Feasibility Study <br />SAIC conducted a Construction and Demolition (C&D) <br />Recovery Feasibility Study to determine if it is viable to <br />recycle materials within the existing C&D waste stream. <br />The study began by examining the incoming C&D to <br />determine the total amount of recyclable materials <br />within the stream (i.e., wood waste, metal, concrete). <br />The cost of running a recovery facility was then <br />determined based on the probable recyclable materials <br />stream and estimated capital and operations costs. The <br />facility operations costs were then compared to the current incoming revenues from the waste stream to <br />determine if the project is economically feasible. This project was conducted in conjunction with the cost <br />of service study for the City of Sioux Falls. The City is currently funding the design and construction of a <br />C&D material recovery facility in their 5-Year capital budget. <br />Solid Waste Facility Permitting, and Transfer Station Improvements Evaluation <br />Hubbard County, Minnesota <br />Our work for this County has included facility planning, siting, and permitting. Hubbard County <br />operates a transfer station, demolition debris landfill, and materials recovery facility (MRF) in Park <br />Rapids (South Site) and a transfer station and demolition debris landfill near Laporte. This County also <br />has experienced growth in population, tourism and commercial development, stressing facility capacity. <br />As a result, they evaluated expansion options. <br />Initially, SAIC assisted Hubbard County in evaluating improvements to the South Transfer Station in <br />Park Rapids. At the time, the South Transfer Station was ill-equipped to handle the large number of self - <br />haul customers, approximately 250 to 300 vehicles per day, which resulted in long waiting lines. <br />SAIC Energy, Environment & Infrastructure, LLC I 2-10 <br />
