Narrative
At 10:11 on 10/29/2019 colonial personnel entering the meridian station observed a strong odor of gasoline, stained gravel, and a small amount of product pooling near the line 01 unit 2 check valve. Internal notifications were made and the control center isolated the station loop from line 01. Contract crews were mobilized and began exploratory excavation around the check valve. At 15:45 it was discovered the cost of repairs and recovery of product would possibly exceed $50,000, thus, associated agency notifications were made. At 16:40, the source of the release was determined to be a failed drain plug on a valve spring canister of the unit 2 check valve. The drain plug was replaced and the system was returned to normal operations.
