34 <br />General Engineering and Environmental Management Services <br />Mecklenburg County, North Carolina <br />HDR has provided a variety of solid waste management services for <br />Mecklenburg County over the past four decades. One of the first projects <br />was the completion in 1972 of a detailed study that evaluated available <br />technologies including incineration, composting, shredding, recycling, <br />baling, and pyrolisis as well as sanitary landfilling. Supporting data included <br />a waste quantity and characterization study determined through two seven - <br />day surveillances at each major disposal site. Also in the early 1970s HDR <br />assisted the County with siting and provided the design for the 160 -acre <br />Harrisburg Park Sanitary Landfill. The design included plans and <br />specifications for all facilities required for normal landfill operations, a <br />computerized earth movement sequence plan, and ultimate use plan for an <br />18 -hole golf course. The facility was one of the first engineered landfills in <br />North Carolina. Upon reaching the final permitted contours, the landfill was <br />closed to waste disposal operations and currently is the home of the <br />Charles T. Meyers municipal golf course operated by the Mecklenburg <br />County Parks and Recreation Division. <br />#*?*&V=ft* FOMMOSM <br />In the 1980s, HDR served as the County's consultant for its solid waste I I <br />management implementation activities, including the preparation of a request for proposals, contract development, <br />facility siting, preliminary design, and construction management of a 235 - tons /day waste -to- energy facility. Located <br />in the university area in the northeast section of Charlotte, the cogeneration facility provided steam to UNC- <br />Charlotte and generated electricity, which was sold to Duke Power. HDR also completed a study to assess the <br />location and size of a transfer and recycling station. The major tasks were the determination of County-wide waste <br />distribution; review existing and planned solid waste management options and available land for the transfer and <br />recycling station; produce a computerized facility siting analysis; develop a Request for Proposals (RFP) for a firm <br />to design the station; and participated in the evaluation of the RFP process. Recyclable materials were expected to <br />include selected paper grades, glass, aluminum cans, used motor oil, and pet containers. An area for deposit and <br />storage of white goods and other scrap metals was also provided. <br />In the early 1990s, HDR assisted the County in conducting a composition study of the commercial waste stream. <br />The study helped substantiate the significant role that commercial waste. recycling could play in the County's <br />recycling program. <br />FOXHOLE LANDFILL <br />More recently, HDR was selected by the County to assist with <br />the design, permitting, construction administration, and <br />regulatory compliance for the operation of the Foxhole <br />Landfill located on Highway 521 in southern Mecklenburg <br />County. Projects completed to date under the General <br />Engineering Services contract include: <br />Preparation of a treatment and processing permit <br />application for the landfill's on -site yard waste facility. <br />HDR worked with NCDENR through the approval <br />Ni uuubs. <br />Preparation of an operational density evaluation report which evaluates the compaction and airspace usage <br />of the landfill operation. <br />Page 19 faq <br />
