Proper landfill operations are critical for protecting groundwater in the High Plains region and minimizing methane emissions. The facility's location in a sparsely populated area reduces community proximity concerns, but ongoing environmental monitoring remains essential.

The landfill is located in the High Plains region of southeastern Colorado, an area with a semi-arid climate and deep groundwater aquifers. Proper leachate management is critical to prevent contamination of these groundwater resources. Landfill gas, primarily methane, must be collected and controlled to reduce greenhouse gas emissions and odor impacts. The rural setting minimizes community proximity issues, but traffic from waste hauling vehicles still affects local roads.
