Maplewood Landfill and King George County Landfills
Waste Management of Virginia, Inc., is proposing to implement two slightly different waste treatment systems at two of its Virginia Landfills. Leachate recirculation would be implemented at its Maplewood Recycling and Waste Disposal Facility (Maplewood Landfill) and bioreactor operations would be implemented at the King George County Landfill and Recycling Facility (King George County Landfill.) The sponsors of the proposed XL project include WM, VADEQ, Amelia County, and King George County. Under the Project, WM is requesting flexibility from the RCRA requirement that prohibits application of bulk liquids in municipal solid waste landfills (40CFR Section 258.28.) The facility is also requesting similar flexibility under Part V of Virginia Solid Waste Management Regulations.
Leachate Recirculation by itself offers the following potential benefits:
- accelerated biodegradation of waste in the landfill
- short term increases in landfill gas generation in order to obtain a shorter overall duration of landfill gas generation
- accelerated biodegradation of potential contaminants in the landfill
- potential for earlier re-use of the landfill for beneficial purposes/potential to avoid new landfill construction
- decreased settlement of the solid waste during landfill operation
Waste Management intends not only to implement the two different waste treatment systems, but also to compare the performance of the two sites in order to evaluate biodegradation potentials of the waste treatment systems, and to examine and costs and benefits associated with the leachate recirculation system vs. bioreactor systems.
