WASHINGTON (AP) — An Ohio-based coal operator is suing the Obama administration, claiming that new federal regulations to cut the amount of coal dust in coal mines are overly burdensome and costly to industry.

The lawsuit against the U.S. Labor Department was filed Thursday in the Sixth U.S. Court of Appeals in Cincinnati. The St. Clairsville, Ohio-based company argues the department failed to adequately take into account the input of technical experts and the coal industry.

The Labor Department did not have immediate comment.

The rule was announced last month. Aimed at reducing black lung disease, it represents the broadest changes to coal dust regulations since the 1969 Coal Mine Health and Safety Act.
