Narrative
On august 11, 2019 at approximately 07:24, the plantation control center received an explosive atmosphere detector (ead) alarm for the collins tank farm east manifold area. The control center contacted the local collins o&m personnel on shift so they could investigate the alarm. The o&m personnel went to the east manifold area and noticed product coming from the rooftop of tank rt-2. The o&m contacted the control center to begin a shutdown of all pipelines for the affecting the east manifold. The shutdown of the pipelines were initiated at 07:26. Upon further investigation of the east manifold area, the o&m personnel noticed a tank line riser valve open for tank 161. He immediately closed the valve. Tank rt-2 overflowed, releasing approximately 27.3 bbls of transmix. After additional assessment of the release site, it was determined this incident might exceed the $50,000 national response center (nrc) reporting criteria. The nrc was promptly notified after this assessment. The source of the product causing the overfilling of tank rt-2 was an open sample valve on the piping header of tank 161 in the facility's east manifold area. Product from the tank header flowed into a closed drain system, accumulated in a sump tank and was then pumped by an automated sump pump into tank rt-2. The tank high-level alarm failed which allowed the tank to overfill.
