The parent company of Columbia Gas of Kentucky plans to replace irregular pipes that its workers installed in five states.
Company spokeswoman Lisa Smith said that of the 28,000 service lines installed with the irregular pipes, 1,200 were in Kentucky. The majority, she said, were in Ohio, with the remainder in Maryland, Pennsylvania and Virginia.
Smith said there are no safety problems with the pipes, which include sections that aren't as thick as the remainder.
"Those irregularities do not create a safety concern," she said. "They just shorten the lifespan of the pipe."
She said workers have performed leak tests on the piping, and "all of our leakage inspections to date have shown no problems."
The irregular piping was discovered by workers in June, and the company then pulled the piping and quarantined it so it could not be used, she said. Columbia Gas worked with the manufacturer to determine the cause of the defect and is now planning a way to replace the piping that was installed.
