Narrative
On 7/6/2021 at 7:16am local time, mpl field personnel identified stained gravel around bv2 at the tates creek station. Field personnel called the control center to shutdown the pipeline. Station was then isolated ahead of excavation to determine leak source. Excavation revealed the leak source to be a corroded 1-inch drain plug on the bottom of bv2. Metallurgical analysis executive summary: the results of the analysis indicate that the corrosion of the failed plug was associated with the internal environment within the valve. Galvanic (dissimilar metal) corrosion likely played a role in the failure given the mating threads of the failed plug did not exhibit any evidence of corrosion. The drain plug was replaced and the line was re-pressurized for a line static test. The line static test passed and the line was approved for restart at 12:15pm on 7/7/2021. On 7/8/2021 at 17:09 local time, a 48 hour nrc update call, #1310089, was made. Final report updates part d question 8 and part g. 11/11/2021 supplemental and final report updated answer to part c question 2 to more accurately reflect the system part.
