EPA Could Consider New Air-Quality Standards for Lead
WASHINGTON - According to a notice published in the Federal Register on March 8, 2006, the U.S. Environmental Protection Agency (EPA) will decide by late September 2007 whether to propose a new air-quality standard for lead.
EPA issued the current air-quality standard for lead in 1978. The Clean Air Act requires the agency to review the standard every five years and issue new standards if it determines that they are required to protect public health. Periodic reviews of the scientific evidence of the health effects of airborne-lead exposure since 1978 have concluded that revisions to the standard were not necessary.
