EPA: Two Pa. natural gas companies settle

PITTSBURGH (AP) – The U.S. Environmental Protection Agency says two natural gas companies have agreed to improve their operations in western Pennsylvania.

In a statement released today the EPA alleges that Mark West Liberty Midstream & Resources and Laurel Mountain Midstream Operating failed to comply with federal clean air regulations to prevent accidental releases of flammable substances.

The EPA says Mark West has agreed to install new emergency equipment and adopt an approved maintenance schedule at all 14 of its compressor stations in Washington and Butler counties.

In another settlement a Laurel Mountain Midstream facility in Washington County has agreed to conduct a safety analysis and make necessary improvements, as well as conduct training with local emergency responders.

The companies did not admit or deny EPA’s allegations.
