Announcing the new rule last Tuesday, officials used charts to emphasize that most mercury toxicity in the United States comes from foreign sources, and they used their cost-benefit analysis to show that domestic controls had minimal impact.
Asked about the Harvard analysis, Al McGartland, director of the EPA's National Center for Environmental Economics, said it was submitted too late to be factored into the agency's calculations. He added that crucial elements of the analysis were flawed.
Interviews and documents, however, show that the EPA received the study results by the Jan. 3 deadline, and that officials had been briefed about its methodology as early as last August. EPA officials referred to some aspects of the Harvard study in a briefing for The Washington Post on Feb. 2.
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.
