It has a 1,206-foot (368m) tall chimney, which was built in 1971.[1] This smokestack was once the tallest in the world for a short period of time. As of 2013[update] it is the sixth tallest, and still the tallest freestanding structure in the Southern United States.[2]
A second 1,000 foot tall smokestack was built in 2006 to comply with emission regulations. On March 6, 2006, a fire broke out at the top of the new stack trapping several construction workers just as they were finishing the installation of the stack's fiberglass liner.[3] Three of the workers were rescued by helicopter evacuation; a fourth worker at the site, Gerald Talbert, died from the accident.[4]
