Three of Pennsylvania’s Republican Congressional lawmakers are cheering a U.S. Supreme Court decision. The high court Thursday upheld a controversial ruling that will open the door to completing the Mountain Valley Pipeline. The MVP will ship large quantities of natural gas from the Marcellus shale gas fields, some of which are under Pennsylvania, to Virginia. U.S. Representatives John Joyce, Dan Meuser and Guy Reschenthaler are all praising the decision because they say it will have a huge economic impact on Pennsylvania’s natural gas industry. Opponents say the six-billion-dollar project will lock in decades of emissions. The high court’s decision paves the way for the final section of the 303-mile pipeline to be completed in Virginia before winter.
