SouthTex is currently operating a landfill gas treating plant on the City of Ft. Smith Landfill in Ft. Smith, Arkansas in partnership with Cambrian Energy.  The Ft. Smith plant is designed to be a smaller, more efficient version of the Johnson County Landfill treating plant, and has been operating since May of 2005. 

The Ft. Smith project is currently producing approximately 2.5 MMSCFD (1750 scfm) of landfill gas, with growth expectation over the 70 year life of the project.  The plant serves a local pipeline with a 975 BTU/scf specification, requiring propane injection for BTU enhancement as an added process element.
