Narrative
The incident occurred while performing routine valve maintenance (conducting valve stem packing material insertion) at the mile post 11.48 valve. The pipeline was shutdown prior to the incident. The valve body pressure had not been bleed off prior to removing the valve plug, causing the release inside the valve structure. The valve is located in a below grade structure. The structure was evacuated due to gasoline vapors and emergency response was initiated. A total liquid volume of 700 gallons was removed from the valve structure with a vacuum truck, which contained approximately 500 gallons of gasoline. The local fire department injected approximately 200 gallons of water mixed with 2 gallons of aqueous fire-fighting foam (afff) to suppress gasoline vapors within the valve structure. Two employees were involved with the maintenance activity. Employee #1 was in training and was observing the maintenance activity. Employee #2 was performing the maintenance activity and was oq'd for the task. Following the incident, employee #2 was immediately disqualified and re-qualified for the task on 6/30/17. Approximately one cubic yards of soil was removed via hydro-excavation. The minnesota pollution control agency has determined the cleanup and response activities are adequate and no additional actions are required. Supplement/final update (12/19/2018): part h.
