Officials at Williams Co., one of the companies behind the Bluegrass Pipeline, have said that their pipeline would be safe for nearby residents.
The Adair County explosion Thursday caused a drop in pressure in the pipeline, known as Line 200, that was detected at 2:05 a.m. by operators at Columbia Gulf Transmission, according to a media release.
A different section of Line 200 that passes through Estill County ruptured in January 2012, sending flames into the air and evacuating about 30 families. No one was injured.
Columbia Gulf Transmission is part of the Houston-based Columbia Pipeline Group, which has about 1,400 miles of pipelines operating in Kentucky. A company spokeswoman on Thursday said the two fires along the same pipeline system "does not mean that the pipeline facilities or circumstances are comparable."
Spokeswoman Katie Dupuis Martin said officials are working to confirm the age of the pipeline that ruptured on Thursday.
