A five-year, $57 million plan to clean up a polluted Pocatello Superfund site was approved by federal regulators on Tuesday, according to the Associated Press.
Contaminated areas near U.S. Interstate 86, once the site of a plant belonging to FMC Corp., are located on the reservation of the Shoshone-Bannock Tribes.
During the intervening years, the site has been plagued by other problems, including "burping" ponds — volatile waste repositories that produce phosphine gas that smells of rotten fish and can damage respiratory, nervous and gastrointestinal systems.
Based in Philadelphia, Pa., FMC had $3.4 billion in sales in 2011. The company operated the phosphorous production plant from the 1940s to 2001.
