Narrative
Original: air patrol reported a possible leak on the c47 line at around 10:00 am. Operations dispatched a contract crew to investigate the possibility of a leak on our pipeline. At 1:55 pm, once we determined that the total cost would meet nrc reporting criteria, the nrc was contacted by the pipeline control center at 2:15 pm. Update: (7/13/17) a plidco clamp was installed over the leak site. Line c47 has been idled of all hazardous material and is operating under a nitrogen blanket. Idling this line remediates any necessary repairs or analysis due to the absence of hazardous material.
