TEQ One Mic Stand: Columbia Gas Legacy Cross Bore Program

Jeff Maharowski, Columbia Gas Cross Bore Program Leader, and Lisa Rahuba, Columbia Gas Sr. Cross Bore Coordinator, step up to the One Stand to detail the Legacy Cross Bore Program.

Cross bores occur when natural gas lines or other utility lines are inadvertently installed through sewer lines. While rare, cross bores can go undetected for months or years. And, they can pose an unknown risk. When sewer line blockages are cleared with mechanical rotary devices or high water pressure, a gas line could be damaged and allow natural gas to migrate into homes or buildings through the sewer line.

Jeff and Lisa will detail some of the new technologies like artificial intelligence, that are being deployed to better locate and mitigate cross bores. Learn what to look for if crews are in your neighborhood as part of the Legacy Cross Bore Program.
