Narrative
On 8/11/21, at approximately 00:36, a houston (htn) colonial operator smelled product conducting a yard check and began investigating the source. The operator noticed stained rocks surrounding the line 2 (l2) eva shipper valve. This led the operator to observe ultra low sulfur diesel (ulsd) in 3 access wells next to the valve. The operator informed the on-shift a & b operators. Htn l2 was shutdown pending investigation of the leak source and notifications were made to appropriate personnel. Operations at this valve required further investigation to determine the responsible party. A potential responsible party submitted a nrc call (nrc incident report # 1313343). The summary of this call included joint investigation actions underway to determine the leak source and responsible party. 8/12/21, colonial confirmed ownership of the leak source (responsible party). Colonial found the leak to be a result of a valve body guide plug malfunction. At approximately 11:00 cst, colonial discovered the spill response costs may exceed $50,000 and made a notification to the nrc (nrc incident report #1313487). Additionally, PHMSA aid was contacted to clarify incident report # 1313343 discussed above was the same leak. Other notifications were made as required. Approximately 100 gallons of ulsd was released and contained onsite. On 8/14/2021, colonial conducted a 48 hour updated notification to nrc incident # 1313487. This notification reported no significant changes other than the valve repair was completed on 8/13/21. An ia will be conducted for this incident.
