Bi County Gas Producers, LLC:
Landfill-Gas-To-Energy Project

Project Location:
Woodlawn, TN - Bi-County Solid Waste Landfill

LF Owner:
Montgomery County, TN, Stewart County, TN


The GCCS consists of 26 vertical extraction wells in the existing Class I landfill (MSW) and 15 vertical wells in the Class IV landfill (C&D). There are also an additional 20 LFG extraction components, including leachate cleanout pipes and collection points. The initial GCCS was installed in 2011, with expansions in 2013 and 2014 that included both replacement and new wells. The wellfield has approximate physical coverage of existing disposal areas of around 60%. Management has not expanded the collection system since there is sufficient gas to run at full capacity.

Scope of Work:

  • Construct Gas Collection and Control System (GCCS) loop around landfill with 18”, 10” and 8” HDPE header lines
  • 21 vertical gas wells, 2 leachate cleanout tie-ins, and 3 condensate sumps
  • Installed Flare and Treatment Skids
  • Installed Caterpillar 3516A+ and Caterpillar 3520A+ engines

Noteworthy: BCGP was the first project in the United States to use a Cat 3516A+ for a LFG Project installed by Advance One Development, LLC.
