Narrative
During the field portion of a PHMSA integrated inspection on may 11, 2021, block valve 232 was found by cenex pipeline staff and the PHMSA inspector to be dripping a small volume of product from the body bleed valve. Controllers opened a downstream valve to bleed pressure/volume away from the site and oq qualified field staff tightened the bleed within minutes of arriving on-site to stop the leak. No repair was needed beyond tightening the bleed. Release estimate was based on volume of soil cleanup associated with the release. No leak alarms were received because the leak alarm thresholds were not met. Release was result of maintenance. Staff opened body bleed to drain valve. Upon completing maintenance, staff closed the body bleed but did not get it fully tightened, resulting in a small drip type of release.
