Missouri must now track and control landfill emissions, like every other state

The US environmental regulators have approved Missouri's plan to control air pollution from its landfills. This means the state must now enforce rules to capture methane and other gases from its trash dumps.

For years, some states lagged in enforcing federal clean air rules for landfills. This approval means Missouri can no longer avoid its obligations. It brings the state in line with national standards for managing waste emissions.
