The Tronox site is located in Texarkana, Bowie County, Texas. The Facility was previously owned and operated by Kerr-McGee Chemical Corporation (Kerr-McGee) who sold the facility to Tronox. The Facility property includes approximately 500 acres of upland and bottomland hardwoods and flood plains of Waggoner, Days, and Howard Creeks. Bottom sediment and sludge generated from the treatment of wastewaters from wood preserving processes was released into Waggoner, Days, and Howard Creeks and data indicated elevated levels of PAHs, in addition to arsenic and PCPs. The trustees determined that a minimum of 144 acres of constructed freshwater wetlands would be required to offset lost services due to releases at or from the Facility. A settlement was reached with the responsible party in January of 2015, providing more than $14 million for restoration for this site. This settlement is part of a larger $5.15 billion settlement with Anadarko Petroleum Corporation, the largest environmental settlement in U.S. history.
