EPA Weakens New Lead Rule After White House Objects
WASHINGTON - After the White House intervened, the
Environmental Protection Agency last week weakened a rule on airborne
lead standards at the last minute so that fewer polluters would have
their emissions monitored.
The EPA on Oct. 16 announced
that it would dramatically reduce the highest acceptable amount of
airborne lead from 1.5 micrograms of lead per cubic meter to 0.15
micrograms. It was the first revision of the standard since EPA set it
30 years ago.
a close look at documents publicly available, including e-mails from
the EPA to the White House Office of Management and Budget, reveal that
the OMB objected to the way the EPA had determined which lead-emitting
battery recycling plants and other facilities would have to be
documents show that until the afternoon of Oct. 15, a court-imposed
deadline for issuing the revised standard, the EPA proposed to require
a monitor for any facility that emitted half a ton of lead or more a
The e-mails indicate that the White House objected, and in
the early evening of Oct. 15 the EPA set the level at 1 ton a year
According to EPA documents, 346 sites have emissions of
half a ton a year or more. Raising the threshold to a ton reduced the
number of monitored sites by 211, or more than 60 percent.
EPA also required states to place monitors in areas with populations of
500,000 or more. But the Natural Resources Defense Council, an
environmental group that pushed for tougher lead standards to protect
public health, said that a single monitor in a large city was different
from a monitor placed near a plant.
"We don't expect the urban
monitors to be effective to get the hot spots that the site-specific
monitors can get," said Gina Solomon, an NRDC scientist and a professor
of medicine at the University of California at San Francisco. "The
monitoring network has a lot of gaps in it."
Airborne lead can be
inhaled, but the main way people are exposed is when they ingest it
from contaminated soil - for example, when children play in a
contaminated area and put dirty hands to their mouths.
originally estimated that at the half-ton annual emissions cutoff, it
would need from 150 to 600 monitors, said EPA spokeswoman Cathy
Under the final rule with the 1-ton cutoff, the
requirement will be 135 site-specific monitors and 101 urban monitors
in areas of 500,000 or more people, she said. There are 133 monitors
Milbourn said that EPA Administrator Stephen Johnson set the
requirement for monitoring at sites that emit 1 ton or more of lead a
year because it was "an approach that would reduce the burden to states
but would still assure monitoring around those sources" that might
violate the air-quality standard.
The Battery Council
International, a trade group that represents U.S. lead battery makers
and recyclers, told the EPA in public comments in August that the
proposed half-ton threshold was "unjustifiably low."
Milbourn said that state and local officials should monitor any site they think might violate the new EPA standard.
other words, states may go beyond the minimum monitoring requirements,"
and EPA will help them identify sources that emit less than a ton per
year but still might produce amounts of lead in the air that are higher
than the rule allows, she said.
Lead in the air was greatly
reduced three decades ago when the government ordered it removed from
gasoline, but it is still emitted by lead smelters, cement plants and
Scientific studies have found that lead is dangerous
at much lower levels in the human body than previously thought. The
studies show that children's nervous systems are especially vulnerable,
and that lead exposure can result in IQ loss and damage to many
