Narrative
A dozer that was ripping frozen ground punctured a 4" natural gas line. The line released natural gas until it was shut in and isolated. The line was properly marked by the operator, but the contractor failed to maintain distance from the pipeline while excavating. The unintentional release of gas totaled 751 mcf which does not meet the reporting threshold of 3 million cubic feet of gas, but wbi energy deemed it significant to report the incident. Natural gas service was lost to the towns of arnegard, nd and watford city, nd. Supplemental report 3/7/13 revised data in question c.3.A. From 4.5 to 4, revised data g3.6 from no to yes, and marked one-call system in g3.6.A.
