Oklahoma Environmental Management Authority (OEMA) Landfill - Union City, Oklahoma Solid Waste Management

The Oklahoma Environmental Management Authority (OEMA) Landfill is a municipal solid waste landfill located in Union City, Canadian County, Oklahoma. Operating since 1974, it serves as a key waste disposal facility for the region, with an anticipated closure year of 2027. The landfill is owned and operated by the Oklahoma Environmental Management Authority. As a landfill in the United States, OEMA Landfill operates under the regulatory framework of the US EPA, including RCRA Subtitle D for municipal solid waste and Clean Air Act regulations for landfill gas management. The facility likely employs standard landfill practices such as waste compaction, daily cover, and leachate collection to mitigate environmental impacts. Its long operational history suggests it has played a significant role in regional waste management. The landfill's environmental significance lies in its management of landfill gas and leachate. Proper gas collection systems help reduce methane emissions, while leachate management protects local groundwater. Located in a rural area of Oklahoma, the facility serves surrounding communities, and its closure in 2027 will require planning for post-closure care and alternative waste disposal options.

The OEMA Landfill is situated in a rural area of Canadian County, Oklahoma, where groundwater protection is a key environmental concern. Landfill operations require robust leachate management systems to prevent contamination of local aquifers. Additionally, methane generation from decomposing waste necessitates gas collection to reduce greenhouse gas emissions and mitigate odor impacts on nearby communities. The facility's proximity to agricultural land and residential areas underscores the importance of proper operational controls.
