Commission says 428 pipelines failed leak test after Colorado explosion

29 September 2017

The Colorado Oil and Gas Conservation Commission (COGCC) said that 428 oil or gas pipelines near occupied buildings failed a leak-detection test that the state ordered following the April blast that destroyed a house, killed two and seriously injured a third in the town of Firestone. The blast was traced to a nearby uncapped gas line.

COGCC identified 120,815 flowline segments within 1,000 feet of a building as a result of the Flowline Notice to Operators issued after the Firestone blast, and operators submitted documentation showing that 107,297 of those lines passed a pressure test or were abandoned.

The commission is now tracking follow-up work on the 428 lines that did not pass the leak test. It is also working with operators to determine the status of the remaining 13,090 flowline segments.

COGCC says the latter category includes lines that might not have been tested, the data submitted was incomplete or in error, or the flowline segment was previously capped, shut-in, abandoned, or was not within the scope of the notice to operators.
