Oklahoma must now control landfill emissions, like every other state

The US environmental regulators are approving Oklahoma's plan to control air pollution from its landfills. This means Oklahoma's landfills will now have to meet the same emission standards as those in other states.

For years, Oklahoma had not submitted a plan to control emissions from its municipal solid waste landfills, even though federal law required it. This approval means the state must now enforce those rules. It closes a loophole that allowed Oklahoma's landfills to operate under less stringent environmental oversight than most of the country.
