Narrative
At 08:20 on 5/15/13, a third party operator reported a leak on a valve bonnet at the manual block valve site (milepost 62.5) near levelland, texas. A technician was dispatched and arrived onsite at 09:47. Upon arrival, the technician noticed a minor leak on the valve and attempted to repair the leak. However, the leak could not be stopped and the line was shut-down and blocked in at 10:55. Note: the particular valve in question was not blocked initially. The pipeline was shut down by pipeline control at 1055 consistent with pl control protocol in an effort to reduce the pressure as attempts were made to re-pack the valve that was leaking. Line pressure @ 1055 was approximately 200 psi when repair attempts commenced. At 11:49 it was determined the leak had met the definition of an accident and the estimated cost to repair the leak would exceed $50,000 and the nrc was notified at 12:23 local time. At 08:00 on 5/16/2013, nitrogen inert was injected at levelland station for approximately 23 miles. The valve at milepost 62.5 was removed and replaced with a flanged type valve. The line was restarted at approximately 0035 5/17/2013.
