Narrative
At approximately 1030, concord field personnel noticed a stain between surge system 2 and 3 in the concord manifold area. Operators then shut down the transfer between the surge systems, which was underway for maintenance purposes (breakout tank cc 6 valve repair). Field maintenance employees exposed the area by hand and quickly discovered a leak (gasoline) from the bottom (6 o'clock position) of a two inch auxiliary (transfer) line. They immediately contained the leak with buckets and continued removing impacted soil. The two inch line is connected to the surge transfer line but has not been used in some time. Field personnel removed the line (a 7 foot 2 inch section) and blinded off the end piece to the transfer line. Release notifications were completed. Approximately 92 gallons were released and recovered. Subsequent ultrasonic thickness and shear wave examinations concluded internal metal loss (corrosion) as the cause of the release. Note: part g1, #13 corrosion coupons are strategically placed and monitored to ensure corrosive products are not introduced into the pipeline, however, this 2-inch transfer line allowed water drop out.
