GRAND JUNCTION, Colo. (KKCO) -- Nearly three months after the explosion that leveled two homes, the City of Grand Junction says its workers had no role in the cause.
Advanced Engineering Investigations (AEI) completed a preliminary report stating the city did not contribute in any way to the cause of the explosion.
The city says the exact cause is still under investigation.
“This is an important finding for us to receive”, states Grand Junction Mayor Sam Susuras. “While we were comfortable all along that the City had no role in the cause, we are pleased to have official confirmation of this fact.”
The report, dated last week, says on March 19, Apeiron workers were performing directional drilling across N. 7th Street on on the south side of Orchard Ave. and 7th St. intersection.
One man drilled down about 60 inches and may have hit a line while creating a pilot hole. The struck line was six inches in diameter, had medium pressure and was used exclusively by Colorado Mesa University.
According to the report, the gas that traveled south leaked into the home at 1752 N. 7th Street and caused it to explode and burn. The flames spread to the home next door and burned it to the ground as well.
While the city was exonerated of responsibility, AEI will continue to investigate to what degree the actions of Safe Site Utilities, Aperion and Xcel Energy contributed to the explosion.
