Narrative
At approximately 1526 cdt on 18mar13, the cpl controller observed a rapid drop in pressure and flow rate at the bear river block valve on the no. 1 salt lake to burley line. Controller made notification that the pipeline would be shut down and completed shutdown at 1530 cdt. Controller closed the upstream and downstream rov's at 1534 cdt. Ground and air patrols began searching the right of way for a leak . At 1925 cdt on 18mar13, a salt lake field team employee confirmed a release of diesel at mp 45.0, near willard bay state park. The release was to land and to a drainage ditch, that drains to willard bay reservoir. Containment boom was placed in the drainage ditch to prevent product migration to the reservoir. All free standing product has been removed and cpl personnel are removing the contaminated soil around the leak site. The damaged pipe was excavated and found to have a longitudinal seam split of approximately 74 inches in length.The damaged pipe was cut out and sent to the lab for analysis. After replacing the damaged pipe, the pipeline system was put back in service at 13:23 cdt on 30mar13. Lab analysis files are attached (7 pdf files) below.
