South Fayette commissioners on Wednesday unanimously voted to join other local municipalities in a challenge to the state’s new Marcellus Shale law, known as Act 13.

Peters Council plans to formally address the motion at Monday's meeting—7:30 p.m. in council chambers—because it's intended action was not given the necessary 24 hours.
