Narrative
As a result of a tornado warning and a clear observation that emergency preparations were necessary, devon's cana plant emergency shut down (esd) system was activated by cana plant operations personnel at approximately 4:00p.M. Cst, at which time the employees sought shelter in the on-site storm shelter. At approximately 4:25p.M. Cst, the tornado had passed. After emerging from the tornado shelter, plant personnel began to make initial observation reports from a safe distance to devon's gas control center as well as devon management. It was evident from observation that damage was incurred at the residue sales header (the downstream portion of devon's ~3420ft regulated residue transmission pipeline that delivers residue gas from the cana plant to third party pipelines--currently oneok and enogex). Immediate actions were aimed at protecting life first and property second, and included securing the site perimeter from any unauthorized activity. Devon stood up a local incident command system (ics) structure and mobilized a team comprised of operations and environmental, health & safety (ehs) representatives to conduct initial inspections and safety assessments prior to permitting activity within the plant. Ics was later stood down and a project team was established to conduct more detailed assessments. Repairs to the residue sales header were made in accordance with 49 cfr part 192 and the header is planned to be returned to service wednesday july 20, 2011.
