Coal Combustion Residuals
(Fly-Ash) - Proposed Rule
-
EPA sets new emission limits on Cement Plants
-
When fully implemented in 2013, EPA estimates the annual emissions
will be reduced:
·
Mercury – 16,600 pounds or 92 percent
·
Total hydrocarbons – 10,600 tons or 83 percent
·
Particulate Matter – 11,500 tons or 92 percent
·
Acid gases – (measured as hydrochloric acid): 5,800 tons or 97
percent
·
Sulfur dioxide (SO2)– 110,000 tons or 78 percent
·
Nitrogen oxides (NOx) – 6,600 tons or 5 percent
-
Mercury in the
air eventually deposits into water, where it changes into methylmercury,
a highly toxic form that builds up in fish. People are primarily
exposed to mercury by eating contaminated fish. Because the developing
fetus is the most sensitive to the toxic effects of methylmercury, women
of childbearing age and children are regarded as the populations of
greatest concern.
-
EPA estimates that the rules will yield $6.7 billion to $18 billion
in health and environmental benefits, with costs estimated at $926
million to $950 million annually in 2013. Another EPA analysis estimates
emission reductions and costs will be lower, with costs projected to be
$350 million annually.
