Process Description: Orchard Hills Sanitary Landfill (the Landfill) is a 283-acre MSW landfill, owned and operated by Landfill Management Co. since the 1980s. The Landfill accepts approximately 1,000 tons of waste per day that is composed of MSW and construction and demolition waste, containing gypsum. The Landfill also accepts asbestos and keeps GPS coordinates on the locations. The Landfill is cunently filling Cell 7B which was started three years ago. Starting with Cell 5 through Cell 7B, the Landfill has a dual composite liner. Part of the Landfill is pre-Subtitle D and has a synthetic cap. Interim cover along the rest of the Landfill is composed of sand, clay, and topsoil. Daily cover is put down over the active waste area after filling each day and is PosishelL but dirt is used during the winter months. Leachate is gravity fed to a tank near Cell 6 and is sent through a treatment system. The treatment system has a settler, pH adjustment, sand filters, and a reverse osmosis (RO) process. Wastewater from the RO process is sent back to the Landfill: aJ1d filtered water through the RO process is discharged to ditches. The Landfill has approximately 248 active gas extraction wells that are mostly vertical wells with a few horizontal wells. There are numerous caisson wells to increase durability. All gas from the wells is sent to three engines or a utility flare. The engines have a total capacity of 4 Megawatts. The utility flare has a capacity of 2,000 standard cubic feet per minute (scfrn). Total flow to the control devices is approximately 1,200 scfm at 37 inches of vacuum. Staff Interview: The Landfill plans to start work preparing a new cell in the next month. Mr. Shaw walks with wellhead monitoring staff on occasion to e.nsnrc that well monitoring is performed properly.
