Asserting that there is no clear scientific evidence that more stringent standards would produce additional human health and environmental benefits, the EPA is proposing to retain without change the 2012 National Ambient Air Quality Standards (NAAQS) for particulate matter (PM).

In its current review of its 2012 National Ambient Air Quality Standards (NAAQS) for particulate matter (PM), the EPA may need to closely consider a new report from the National Toxicology Program (NTP) on the relationship between traffic-related air pollution (TRAP) and hypertension during pregnancy.
A 1,880-page draft report on the risk particulate matter (PM) imposes on human health may undergo extensive revisions because the EPA’s powerful Clean Air Scientific Advisory Committee (CASAC) has concluded that the methods used by the authors of the report are flawed and that the authors’ estimated impact PM has on mortality is overstated.
Two Clean Air Act (CAA) provisions governing deadlines for submission of state implementation plans (SIPs) to bring areas into attainment with the National Ambient Air Quality Standards (NAAQS) for particulate matter (PM) were at the core of a recent decision by a panel of the U.S. Court of Appeals for the D.C. Circuit.
