Review of the National Ambient Air Quality Standards for Lead

a.k.a. Lead NAAQS Review

RIN: 2060-AQ44 (What's this?)

Docket No.: EPA-HQ-OAR-2010-0108 (What's this?)

Current Phase: Proposal (What's this?)

Under the Clean Air Act Amendments of 1977, the EPA is required to review and if appropriate revise the air quality criteria for the primary (health-based) and secondary (welfare-based) national ambient air quality standards (NAAQS) every 5 years.

On November 12, 2008, the EPA published a final rule to revise the primary and secondary NAAQS for lead to provide increased protection for public health and welfare. The EPA has now initiated the next review. This new review includes the preparation of an Integrated Review Plan, an Integrated Science Assessment, and, if warranted, a Risk/Exposure Assessment, and also a Policy Assessment Document by the EPA, with opportunities for review by EPA's Clean Air Scientific Advisory Committee and the public. These documents inform the Administrator's proposed decision as to whether to retain or revise the standards. The proposed decision was published in the Federal Register with opportunity provided for public comment. The Administrator's final decisions will take into consideration these documents and public comment on the proposed decision.

Potential Effects

Children's Health
This rule is likely to address an adverse impact on childhood lifestages, including prenatal (via exposure to women of childbearing age). The potential adverse impacts are expected to be due to exposure (i.e., children and/or women of childbearing age are more likely to be highly exposed than other lifestages).

Environmental Justice
This rulemaking involves a topic that is likely to be of particular interest to or have particular impact upon minority, low-income, tribal, and/or other vulnerable populations because:

  • This topic is likely to result in the collection of information or data that could be used to assess potential impacts on the health or environmental conditions of vulnerable populations.
  • This topic is likely to affect the availability of information to vulnerable populations.

State Governments
Likely to be involved in the implementation of this rule.
