Digging Near a Pipeline


MarkWest needs help to prevent pipeline emergencies. The primary cause of pipeline leaks is damage from earth moving and construction parties (other than the pipeline company).  If you are working on or around our equipment:

  • Contact the One-Call Center and/or MarkWest at least two days before planned work activity
National Call-Before-You-Dig Number 8-1-1
Kentucky 1-800-752-6007
West Virginia 1-800-245-4848
Michigan 1-800-482-7171
New Mexico 1-800-321-ALERT
Oklahoma 1-800-522-6543
Texas 1-800-245-4545
Pennsylvania 1-800-242-1776
  • Do not make unauthorized use of a right-of-way
  • Do not disturb the ground until the pipeline is marked
  • Abide by all location markers and instructions provided by the MarkWest representatives
  • Carefully hand dig and probe until the pipeline is exposed
  • Do not use power equipment around the pipeline
  • When backfilling, provide proper support for pipelines and ensure adequate soil cover on top. Use suitable rock-free material to avoid damage to line coating
  • If the pipeline is damaged or poses a threat to the public, immediately leave the area
  • When you reach a safe area, call the Markwest 24 hour emergency number and 911
