Feb. 11, 2023 Update
U.S. EPA has issued a general notice of potential liability letter to Norfolk Southern to document the release or threat of release of hazardous substances, pollutants or contaminants to the environment following the train derailment. The letter outlines EPA cleanup actions at the site and the potential to hold the railroad accountable for associated costs. The letter can be found under the Documents section of this website.. ----
