Narrative
On july 31, 2016 at approximately 11:45 hours, the mont belvieu control center (mbcc) received a call from a 3rd party who reported ice crystals on the ground, and a faint lpg odor in the vicinity of line txl-0092 (targa north route) in highlands, texas. This line was not flowing at the time. Emergency response procedures were implemented. Buckeye personnel arrived on site at 12:50 and confirmed buckeye's involvement, and required notifications were made. The leak was identified as a crack in one of the two dents found in the pipe an estimated total of 2.0 barrels of propane fuel was released. The cut section of pipe was sent for metallurgical analysis to determine the root cause of this release. 12/19/2016 final metallurgical analysis report showed: two dents were found in the immediate vicinity of the crack like feature. Ut measurements showed the thinnest wall thickness to be .230' in the area immediately surrounding the anomaly. The affected section of the line was sent for metallurgical analysis. Lab analysis of the release location concluded that the pipe leaked at a colony of stress corrosion cracking at a region of mechanical damage. Also adjusted part e (9) based on investigation into whether or not the controller(s) or control room issues were the cause of or a contributing factor to the accident? Per PHMSA request (email) on 04/03/18 on corrections needed to this 7000.1 report. I have made the corrections to part a -q4, q14, 14a, 14b and q18a. I have also corrected part c - q3a.
