Narrative
On 7/13/2020 at 10:15ct, an enterprise pipeline technician identified an oil sheen around mov-a005, the bypass valve for the seaway 1 scraper trap. A hydroexcavation truck was called to the site to expose the underground valve. Once the valve was exposed, it was determined that its bonnet was leaking. An estimated 1 quart of oil was released. The valve was then isolated and its bonnet wrapped in absorbent pads to prevent additional contamination. On 7/15/2020 at 08:30ct it was determined that repair and cleanup costs for the leak would exceed $50k. Upon investigation, it was determined that failure of the valve's o-ring to completely seal caused the leak. For repair, the o-ring was replaced and flange faces on the valve body and bonnet were resurfaced to ensure a seal. Cause of the o-ring failure is undeterminable. Cleanup & repairs are complete and the valve has been placed back into service. No offsite impacts. Nrc: #1281937 at 7/15/2020 08:45ct nrc 48 hour: #1282096 on 7/16/2020 14:11ct
