Maryland’s plea to EPA: Make out-of-state power plants run pollution controls | Center for Public Integrity

Some power plants with smog controls aren’t using them effectively — or at all — and are fouling the air hundreds of miles away as a result.

That’s the conclusion reached by the Maryland Department of the Environment, which petitioned the U.S. Environmental Protection Agency this week to make 19 coal-fired plants run their control equipment throughout the summer, when ground-level ozone — often known as smog — is most likely to form.

Ten of those 19 plants were identified by the Center for Public Integrity in September as “super polluters” because they were among the top 100 U.S. industrial sites for toxic substances pumped into the air, greenhouse gases released, or both, in 2014.

Maryland’s petition focused on releases of nitrogen oxides, a key ozone ingredient. Ben Grumbles, Maryland’s secretary of the environment, said he simply wants the 19 plants to do what his state’s coal plants must: “Run the controls — run the controls every day of the ozone season, and downwind states will benefit significantly from that.”
