Narrative
The orion north 12" pipeline from henrietta to duncan lost pressure while in a static condition. All 12" block valves were closed by operations employees. Foot and vehicle patrol were performed by operations and air patrol flew the line segment in question. Product release area was identified by air patrol just on the north side of US hwy 287. Excavation was performed and discovered pipe coating was shielded causing corrosion which led to the release. Pipe where releases occurred was cleaned and sandblasted, full encirclements were welded on. Later approximately 100' of new 12' pipe was installed in 2 separate places. This line was hydro tested afterwards. Pipeline was restarted at 7:39 on 9/10/11, but not actually operated until 10/10 for a scheduled operation.
