Columbia Ridge LF

As of 2022, Columbia Ridge LF has approximately 66,976,355 tons of waste in place. The total permitted design capacity of the facility is 393,767,649 tons, meaning the site is currently at approximately 17% of its total design capacity. The facility accepts approximately 2,607,058 tons of waste per year based on the most recent annual data. At the current rate of fill, the facility is projected to reach capacity and close around 2131.0.

Columbia Ridge LF has an operational landfill gas-to-energy (LFGTE) project using a Reciprocating Engine system. The facility generates approximately 15.8 million standard cubic feet per day (mmscfd) of landfill gas, of which approximately 10.9 mmscfd is actively collected. The landfill gas contains approximately 51.4% methane content. The gas collection system includes 167 extraction wells. This type of project converts waste-generated methane into usable electricity, reducing greenhouse gas emissions while generating renewable energy for the local grid.

The design specifications call for a total area of 687 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.

Columbia Ridge LF participates in the following environmental programs: leachate recirculation is practiced to accelerate waste decomposition; the facility is permitted as a Research, Development and Demonstration (RD&D) landfill; an LFG energy project with status 'Operational' 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.
