EPA to Probe Missing Mercury
Plants Unable to Account for Tons of Annual Purchases

Under prodding from environmental groups, the Environmental Protection Agency is taking another look at a handful of U.S. chemical plants that cannot account for as much as 65 tons of mercury they may be releasing into the environment each year.
The nine chlorine manufacturers that utilize techniques dating to the 1950s have denied they release enough of the toxic substance to endanger public health. But some environmental groups and lawmakers contend the plants may be posing a more serious health threat than the nation's 11,000 coal-fired power plants that together emit 48 tons of mercury every year.
"There's been a tremendous amount of attention on power plants," said Linda Greer, a senior scientist with the National Resources Defense Council (NRDC). "But there's this sneaky other source that may be as big, if not bigger, that EPA hasn't regulated well at all."
Last December, the EPA issued a new rule to regulate the chemical industry's handling of mercury, but it conceded that the government and industry cannot account for 65 tons of the toxic substance that may be escaping into the environment annually.
Jeffrey Holmstead, an assistant EPA administrator in charge of air policy, confirmed this week that his agency would undertake the review. "Our engineers said we are quite confident that mercury is not going into the air," he said. "Exactly where it's going, we don't know. There's been enough concern about this, we want to go back and see where it's going." ~snip~
