On april 13, 2025, at 8:00 am cdt, during the use of frac tanks at midland tank farm, an enterprise station operator observed a frac tank overflowing into the secondary containment. The operator isolated the flow and remediated the release. The cause was identified as an error in monitoring the frac tank levels.
