The first link is to a proposed rule that has not been implemented yet. It says that it will
"...update emission limits for new power plants under the Mercury and Air Toxics Standards (MATS). The updates would only apply to future power plants; would not change the types of state-of-the-art pollution controls that they are expected to install; and would not significantly change costs or public health benefits of the rule...."
Perhaps that is why no public hearing was requested during the public comment period.
The second link features the opinions of a representative of an indu$try trade group.
Re. the third link:
"This rule, known as the Cross-State Air Pollution Rule (CSAPR), requires states to significantly improve air quality by reducing power plant emissions that contribute to ozone and/or fine particle pollution in other states. In a separate, but related, regulatory action, EPA finalized a supplemental rulemaking on December 15, 2011 to require five states - Iowa, Michigan, Missouri, Oklahoma, and Wisconsin - to make summertime NOX reductions under the CSAPR ozone season control program. CSAPR requires a total of 28 states to reduce annual SO2 emissions, annual NOX emissions and/or ozone season NOX emissions to assist in attaining the 1997 ozone and fine particle and 2006 fine particle National Ambient Air Quality Standards (NAAQS)." EPA
How much is the difference in the NOX and SO2 levels you believe should be allowed compared to the new EPA (2006) standards? How many extra asthma and emphysema cases would the old levels create?
