Subject: [ciaq] Lead Risk Assessment Review (Aug 29, 2007)

Draft Lead Risk Assessment Available for Public Comment

Contact: Enesta , / jones.enesta@...

(Washington, D.C. ? July 31, 2007) EPA is releasing a second draft risk

report as

part of the agency?s review of the national air quality standards for lead.

Completing and reviewing a risk assessment is part of the extensive

scientific

and technical process EPA uses to review any national ambient air quality

standard.

EPA has provided the draft report to the Clean Air Science Advisory

Committee

(CASAC), a group of independent scientific and technical experts that

provides

advice to EPA. The CASAC will review the report at a public meeting in

Research

Triangle Park, N.C. on Aug. 28 and 29, 2007. EPA also is accepting written

comment on the draft assessment until Aug. 29.

This second draft assessment does not include any conclusions or

recommendations

with regard to keeping or changing the current lead air quality standard.

EPA

must propose whether to revise or retain the current lead standards by May

1, 2008,

and issue a final rule by Sept. 1, 2008.

As a result of removing lead from gasoline and other EPA regulations,

airborne

lead concentrations have decreased dramatically in the United States. From

1980 to

2005, national lead air quality levels have dropped more than 90 percent.
