The Mercury Scandal

If you want a single example that captures why so many people no
longer believe in the good intentions of the Bush administration,
look at the case of mercury pollution.

Mercury can damage the nervous system, especially in fetuses and
infants - which is why the Food and Drug Administration warns
pregnant women and nursing mothers against consuming types of fish,
like albacore tuna, that often contain high mercury levels. About 8
percent of American women have more mercury in their bloodstreams
than the Environmental Protection Agency considers safe.

During the 1990's, government regulation greatly reduced mercury
emissions from medical and municipal waste incineration, leaving
power plants as the main problem. In 2000, the E.P.A. determined that
mercury is a hazardous substance as defined by the Clean Air Act,
which requires that such substances be strictly controlled. E.P.A.
staff estimated that enforcing this requirement would lead to a 90
percent reduction in power-plant mercury emissions by 2008.

A few months ago, however, the Bush administration reversed this
determination and proposed a "cap and trade" system for mercury that
it claimed would lead to a 70 percent reduction by 2018. Other
estimates suggest that the reduction would be smaller, and take

For some pollutants, setting a cap on total emissions, while letting
polluters buy and sell emission rights, is a cost-efficient way to
reduce pollution. The cap-and-trade system for sulfur dioxide, which
causes acid rain, has been a big success. But the science clearly
shows that cap-and-trade is inappropriate for mercury.

Sulfur dioxide is light, and travels long distances: power plants in
the Midwest can cause acid rain in Maine. So a cap on total national
emissions makes sense. Mercury is heavy: much of it precipitates to
the ground near the source. As a result, coal-fired power plants in
states like Pennsylvania and Michigan create "hot spots" - chemical
Chernobyls - where the risks of mercury poisoning are severe. Under a
cap-and-trade system, these plants are likely to purchase pollution
rights rather than cut emissions. In other words, the administration
proposal would perpetuate mercury pollution where it does the most
harm. That probably means thousands of children born with preventable
neurological problems.

So how did the original plan get replaced with a plan so obviously
wrong on the science?

The answer is that the foxes have been put in charge of the henhouse.
The head of the E.P.A.'s Office of Air and Radiation, like most key
environmental appointees in the Bush administration, previously made
his living representing polluting industries (which, in case you
haven't guessed, are huge Republican donors). On mercury, the
administration didn't just take industry views into account, it
literally let the polluters write the regulations: much of the
language of the administration's proposal came directly from
lobbyists' memos.

E.P.A. experts normally study regulations before they are issued, but
they were bypassed. According to The Los Angeles Times: "E.P.A.
staffers say they were told not to undertake the normal scientific
and economic studies called for under a standing executive order. . .
. E.P.A. veterans say they cannot recall another instance where the
agency's technical experts were cut out of developing a major
regulatory proposal."

Mercury is just a particularly vivid example of what's going on in
environmental protection, and public policy in general. As a
devastating article in Sunday's New York Times Magazine documented,
the administration's rollback of the Clean Air Act has gone beyond
the polluters' wildest dreams.

And the corruption of the policy process - in which political
appointees come in with a predetermined agenda, and technical experts
who might present information their superiors don't want to hear are
muzzled - has infected every area I know anything about, from tax
cuts to matters of war and peace.

A Yawngate update: CNN called me to insist that despite what it first
said, the administration really, truly wasn't responsible for the
network's claim that David Letterman's embarrassing video of a Bush
speech was a fake. I still don't understand why the network didn't
deny White House involvement until it retracted the charge. But the
main point of Friday's column was to highlight the way CNN
facilitated crude administration smears of Richard Clarke.
