Narrative
At approximately midnight, the occ controller observed line shortages on lv02 (lola system) and contacted the longview field supervisor (fls). The fls sent a technician to finney to investigate. The technician swapped meter 1 and 3 to trouble shoot line balance. Occ controller did not observe a correct in line balance. The fls directed the occ controller to shut down the talco injection to see if the talco meter was the problem. After 15 minutes, occ checked the line balance. The line imbalance continued, so the fls directed the occ controller to shut down the pump at texoma and isolate the entire line. The fls decided to investigate the issue after sunrise for safety purposes. The technicians started at finney and walked the line back to longview. The air patrol surveillance was called out and started checking the line. The air surveillance patrol flew over longview. The longview bkep technician heard the airplane circle and went outside to check what was happening. He then saw the pool of oil near the meter skid and notified the empco longview fls. Shortly thereafter the air patrol reported the release to the empco longview fls. The fls called the other technicians to return to longview. They inspected the site, saw the oil, and contacted omi environmental solutions (contracted spill response). Update 12/17/18 incident time changed from 1050 to 0000 on december 1 based on scada indication of imbalance. Update 12/17/18 part 5, 5.1 updated selection to include metallurgical. Update 12/17/18 - section 14.B.: this pipeline was sold on february 1 2017, and was sold prior to start up. Update 1/24/19 - section g5, number 6. With the most recent hydrotest pressure from 2016.
