regional haze

The state of Wyoming and a coalition of environmental groups have each filed lawsuits against the Environmental Protection Agency over its regional haze plan.

The plan, which was finalized earlier this year, requires new emissions controls for coal-fired power plants. The goal is to reduce air pollution.

The U.S. Environmental Protection Agency has released its final version of a plan to reduce atmospheric haze by cutting emissions from coal-fired power plants in Wyoming.

EPA officials say the plan will improve visibility across wide-open spaces while protecting natural resources and local economies which depend on recreation.

They say the 714-page document adopts most of a separate plan proposed by Wyoming environmental regulators.

The comment period closed Monday on the Environmental Protection Agency’s proposed Regional Haze Plan. The plan seeks to address the issue of air pollution produced by coal fired power plants. Wyoming put together its own regional haze program, but the EPA rejected parts of it, saying it wasn't strong enough, particularly when it came to nitrogen oxide emissions at four plants.
