Narrative
Ngl tech was called out for a station shut-in at approximately 0518 hours. Tech arrived to location at 0623 hours and discovered the filter case door closure leaking. Tech began to isolate the filter at 0627 hours and isolation was complete at 0650 hours. Engineering total loss calculation at (7:33) determined the amount to be 22.35 gallons making the leak reportable. 11/3/20 note: dcp engineering confirmation that the leak was reportable was at 7:33 to dcp pipeline compliance. Dcp pipeline compliance called and reported it to the texas railroad commission at 8:30. Dcp has changed the time in part a, # 4.( earliest local time (24-hr clock) and date an accident reporting criteria was met: from 8:30 to 5:18 although the amount of the leak was not actually determined to be reportable until 7:33 and reported at 8:30. Changed by dwayne hillman @ request of PHMSA inspector alvaro rodriguez. Corrective action: on 8/10 - champion process came on site to install a ratchet add on in order to open the door to check for ovality. Once on site, the tech discovered that the door was very far out of alignment and adjusted the door to be in alignment. Once the door was aligned, the ratchet add on was installed and the door is able to be opened and closed easily utilizing the add on. Mitigation: addition comments added 9/29/2020. Dcp operations made assessments on the sand hills ngl system in september and identified two additional gallop corporation closures like the one located at ramsey meter station. Dcp compliance verified with operations that no issues with those closures existed. The two identified closures were already equipped with the door ratchet assembly like the one installed by gallop corporation at ramsey after the accident. Dcp will also verify the ratchet assembly be included on any future purchases of alike gallop corporation closures from champion in the future.
