New EPA Mercury Rule Omits Conflicting Data
Study Called Stricter Limits Cost-Effective

When the Environmental Protection Agency unveiled a rule last week to limit mercury emissions from U.S. power plants, officials emphasized that the controls could not be more aggressive because the cost to industry already far exceeded the public health payoff.
What they did not reveal is that a Harvard University study paid for by the EPA, co-authored by an EPA scientist and peer-reviewed by two other EPA scientists had reached the opposite conclusion.
That analysis estimated health benefits 100 times as great as the EPA did, but top agency officials ordered the finding stripped from public documents, said a staff member who helped develop the rule. Acknowledging the Harvard study would have forced the agency to consider more stringent controls, said environmentalists and the study's author.

The Harvard study concluded that mercury controls similar to those the EPA proposed could save nearly $5 billion a year through reduced neurological and cardiac harm. Last Tuesday, however, officials said the health benefits were worth no more than $50 million a year while the cost to industry would be $750 million a year.

Mercury is a toxic metal emitted by industrial sources. U.S. power plants emit 48 tons a year, and the new rule establishes an emissions-trading program that is expected to lower emissions to about 31 tons by 2010 and to about 15 tons by 2026. The Harvard analysis was based on similar targets in President Bush's "Clear Skies" legislative proposal. <more>
