Narrative
On july 29, 2018 at 8:30 a.M., summit's control center received a high lel alarm in the pump building that contained pump skid x-1530 located at epping station . The on-duty controller immediately responded to the alarm and shut down the pump. Local operations were dispatched to the station. Upon arrival, local operations discovered a leak from the threaded connection between a pipe nipple and the relief valve. The leak was estimated to be 20 gallons and was contained to the pump building. The leak was cleaned with absorbent pads and placed in containers for disposal. The threaded connection to the relief valve was repaired and the pipeline was restarted. The incident investigation revealed that a previous drip from the threaded connection was identified by operations two days prior to the incident and an attempt to disassemble, reseal and tighten the connection was performed. The incident occurred due to improper installation from the previous repair attempt. Post-accident drug and alcohol testing was not performed due to the incident occurring outside the prescribed testing time limits for the operator personnel involved in the previous repair attempt. Operator qualification for the covered task regarding threaded pipe assembly was suspended for the operations personnel involved in the previous repair attempt. Suspension from this covered task will be in effect until additional training and performance verification are completed. Epping station is located in a hca but this incident was contained to the pump building and operator controlled property and did not affect the hca.
