Narrative
An mpl contractor was working on the new manifold when he smelled hydrocarbons and informed mpl personnel at 13:55 on 4/27/15. The line was immediately shutdown. The area was extensively evaluated including writing an excavation plan, making one-calls, and mobilizing contractors. Upon excavation of the area there was no active leak detected and a pressure test was performed. A small leak was discovered on the flange connection at 01:30 on 4/28/15.The gasket was replaced. Approximately 60 yards of contaminated soil was excavated from the area surrounding the flange. The initial 7000-1 reported the local date and time of the accident as 4/28/2015 at 01:30, since this is the time mpl verified this was an active release. Based on the fact that an active release was discovered following excavation and a pressure test, mpl has changed the local date and time of the accident to 4/27/15 at 13:55 (part a, question 4), the time when hydrocarbon odor was reported.
