Narrative
On october 29, 2014 while inspecting the allen station facility, the smell of diesel was observed and approximately three gallons of refined product was discovered floating on top of water inside a previously excavated area behind the unit 2 pump on the 20" line. The pipeline facility was immediately shutdown and the area cleaned up. The facility piping was visually inspected with no signs of leakage observed. Additionally, piping was blocked in under pressure and held pressure (no pressure decline). The free product appeared to be weathered and possibly from previous contamination at the facility. During clean-up, samples were taken for fingerprinting and analysis, and the laboratory results indicated that the product was "weathered" and likely historic contamination. Subsequent to october 29, 2014, the excavated area was monitored daily without change or signs of a sheen. On november 5, 2014, additional excavation activities were initiated in order to provide assurance that the oct 29th sheen was not related to an active source. While completing these assurance activities, unexpected high lel readings indicative of gasoline resulted in an immediate shutdown of field operations and the entire pipeline system. The local incident management team (imt) was activated on november 5, 2014 and was in place until wednesday, november 12, 2014. During the course of the response, a leak was identified on november 10, 2014 on the unit 1 pump discharge valve body bleed connection. Repair activities on the valve were completed and the 20" pipeline system was then put back into service on november 11, 2014. A total of 7.49 barrels of "non-weathered" product has been recovered.
