The City of Decatur-Morgan County Regional MSW Landfill is a municipal solid waste landfill located in Trinity, Alabama, United States. It serves the City of Decatur and Morgan County, operating under a joint ownership structure. The facility has been in operation since 1980 and is permitted to accept waste until 2051, indicating a long-term regional waste management solution. As a landfill in the United States, this facility operates under the regulatory framework of the US EPA, including RCRA Subtitle D for municipal solid waste landfills and Clean Air Act regulations for landfill gas emissions. The landfill likely employs modern liner and leachate collection systems to protect groundwater, and may have gas collection infrastructure to manage methane emissions. The scale of operations is typical for a regional landfill serving a mid-sized metropolitan area. The landfill plays a critical role in the solid waste management infrastructure of north-central Alabama, providing disposal capacity for residential and commercial waste from Decatur and surrounding Morgan County. Its long operational horizon through 2051 underscores its importance for regional waste planning. Proper management of landfill gas and leachate is essential to minimize environmental impacts on local air and water quality.

The landfill is situated in Trinity, Alabama, within the Tennessee River watershed. The region's humid subtropical climate and relatively high rainfall increase the importance of robust leachate management to prevent groundwater contamination. Proximity to the Tennessee River and local aquifers necessitates careful monitoring. Landfill gas, primarily methane, must be collected and flared or utilized to reduce greenhouse gas emissions and odor impacts on nearby communities. Traffic from waste hauling vehicles also affects local roads and air quality.
