Narrative
Crude oil leaked from an underground flange connection that was not supported properly after installation in the ditch. The lack of proper support may have been a key contributing factor in the loosening of the flange bolts which ultimately led to the release. During line refill crude oil surfaced at this location and migrated into a drainage ditch that ultimately discharges into hawkins branch creek. Approximately one (1) gallon of crude oil impacted hawkins branch creek. After discovery of the release proper nrc and rrc notifications were made. All free oil was promptly cleaned up from the soil and water surfaces. The flanged connection was excavated, proper supporting fill material was installed in the ditch and the flange was re-torqued. The line was refilled, pressurized and checked for leakage. No further leakage was present and the line was returned to service.
