PHILADELPHIA – Environmental groups have filed an appeal of 20 permits issued Monday for the proposed Mariner East Two pipelines. The pipelines would carry highly-flammable, natural-gas liquids including propane, butane and ethane over 300 miles across 17 Pennsylvania counties.

“There’s been misinformation and missing information, and information challenged by the public and by experts, and information challenged by Department of Environmental Protection employees themselves,” she said.
