The incident location is 4.1 miles east of the intersection of TX 71 and TX 271, Talco, Titus County, Texas. An XTO field employee conducting his tank gauging rounds discovered the spill on 13 December 2014 at 0900 hours. XTO Energy is the Responsible Party (RP). The 750 barrel produced water tank was observed to be over flowing salt water and crude oil from the thieve hatch into the facility catchment basin where a previous installed culvert failed resulting in a discharge into an unnamed tributary of White Oak Creek.
