State regulators have ordered Energy Transfer LP – the operator of the Revolution Pipeline that exploded near Monaca last month – to stop all work on that pipeline because of subsequent environmental violations. The state DEP issued an order on Monday to the pipeline company (which is based in Texas), alleging that its construction practices are failing to control erosion and soil movement and have impacted several streams in the area. The company must stop all activities, temporarily stabilize its work sites and submit a series of plans before it can continue with its work to get the pipeline back up and running again.
