Under the Clean Air Act Amendments of 1977, EPA is required to review the science upon which the national ambient air quality standards (NAAQS) are based and the standards themselves every 5 years. On February 9, 2010, EPA published a final rule revising the primary (health-based) NO2 NAAQS to provide increased protection for public 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 toxicity (i.e., the developing fetus, infants, and/or children are more likely to have an adverse response than adult lifestages).
Some of EPA's rulemakings undergo regulatory review (What's this?), as prescribed by Executive Order 12866 and coordinated by the Office of Management and Budget (OMB). The following list describes which of this rulemaking's stages have completed review and published in the Federal Register, if any, and provides links to the review documents where available. Consult the "Timeline" section of this Web page for the dates of each review.

This site provides summaries of priority rulemakings and priority retrospective reviews of existing regulations. We update most of the site at the beginning of each month, though some data is updated more frequently if it is time sensitive. The information on this site is not intended to and does not commit EPA to specific conclusions or actions. For example, after further analysis, EPA may decide the effects of a rule would be different or it may decide to terminate a rulemaking.
