The design specifications call for a total area of 79 acres. The size of a landfill reflects both its operational history and the volume of waste it has processed over its lifetime of service to the surrounding community.

Southern Plains Landfill has an active landfill gas (LFG) collection system in place. The facility generates approximately 1.9 million standard cubic feet per day (mmscfd) of landfill gas. Of that, approximately 1.1 mmscfd is collected by the system. The gas contains approximately 40.8% methane, which can be captured for energy generation. The facility operates 74 gas collection wells. Flares are in place at this facility. LFG collection reduces greenhouse gas emissions and, in some cases, generates renewable energy for the grid.

Southern Plains Landfill participates in the following environmental programs: leachate recirculation is practiced to accelerate waste decomposition; an LFG energy project with status 'Candidate' is associated with this site. These initiatives help reduce the environmental footprint of landfill operations by capturing resources, reducing greenhouse gas emissions, and diverting material from direct disposal. Contact the facility or its operator for more details on current environmental compliance status.
