Narrative
On october 6, 2014, at approximately 4:58 pm energy transfer company (etc) confirmed a release on the wise jack county extension, 8" in wise county, near chico, texas. The pipeline is an intrastate natural gas transmission pipeline located in a rural area (class 1), under the jurisdiction of the texas railroad commission (system id# 630262). The incident was reported to the trrc and also to the nrc under id: 1097551. There were no fatalities, injuries, evacuations, road closures, explosions, fire, media interest, spills or any response by an emergency official. The nearest structure intended for human occupancy is 0.25 miles from the incident site. At 3:31 pm, etc gas control received notification from a targa- chico plant employee that there was a possible line rupture south of their facility. Pressure indicated a leak and upstream targa automatic valve was closed at 3:40 pm. At 4:22 pm, etc bvs15 was closed downstream. This isolated the site of the possible rupture to allow further evaluation. At 4:58 pm, etc employees arrived on scene of the rupture and confirmed that the leak was on the chico 8" pipeline and was depressurized. The scene was secured until repairs could be made.
