On March 8, 2010, Norfolk Southern Railway Company agreed to pay $4 million penalty to resolve alleged violations of the Clean Water Act (CWA) and hazardous materials laws for a 2005 chlorine spill in Graniteville, S.C. Under the settlement filed in federal court in Columbia, S.C., Norfolk Southern will be required to pay a civil penalty of $3,967,500 for the alleged CWA violations, to be deposited in the federal Oil Spill Liability Trust Fund. The alleged CWA violations, included in an amended complaint filed in March 2009, are for the discharge of tons of chlorine, a hazardous substance, from a derailed train tank car and thousands of gallons of diesel fuel from ruptured locomotive engine fuel tanks. For the alleged Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) violation for failure to immediately notify the National Response Center of the chlorine release, Norfolk Southern will pay a penalty of $32,500, to be deposited in the Hazardous Substance Superfund. Under the terms of the agreement, Norfolk Southern will provide incident command system training to environmental and transportation personnel; stock nearby Langley Pond with at least 3,000 fish to replace fish killed by the chlorine spill; and post the telephone number for the National Response Center to facilitate spill reporting. Further, the settlement includes a supplemental environmental project (SEP) valued at $100,000 to plant vegetation along the banks of Horse Creek to decrease erosion and sedimentation, thereby improving water quality in Horse Creek.
