Narrative
On july 20, 2015 at 12:50 pm while performing rounds at the oregon metering facility, the station electrical technician discovered a release from a meter run isolation valve (151-v-113) in the meter skid containment area. Upon immediate visual inspection, 100 gallons of product was estimated to have originated from the failed 1/2" block and bleed tubing attached to the body of the valve. After dimensions of impacted soil were taken by a pipeline maintenance supervisor, a revised estimate of 252 gallons was calculated. The estimated cost of cleanup was expected to exceed the reporting threshold of $50,000, so the nrc was notified (nrc report # 1123318). The meter run was isolated to prevent further release of product and the station technician replaced the body bleed failed tubing. A field examination of the failed tubing showed localized pitting at the manufactured bend. The pipeline maintenance crew arrived on site and executed cleanup. Approximately 40 yards of contaminated soil was removed and disposed of at an approved site. The failed tubing has been sent in for a failure analysis.
