Narrative
On november 11, 2017 at approximately 10:47 cst an integrity dig crew working on line 5 discovered a pinhole leak while sandblasting. The pinhole leak in the long seam was associated with a pipe mill weld repair. No oil reached the ground. The pipeline was immediately shutdown. A notification to the nrc (# 1197057) was made when the incident was deemed reportable after deciding to install a plidco repair coupling which would trigger the $50,000 threshold. The repair was made and site restored. Line 5 was restarted at 6:30 cst on november 12. The actual volume released at mp 1275.09 was 0.00013 gallons. The PHMSA portal does not recognize volumes less than 0.01 barrels therefore that is the volume entered.
