The EPA issued a final rule on November 12, 2008, (effective date January 12, 2009) that revised the primary and secondary National Ambient Air Quality Standards (NAAQS) for lead and associated monitoring requirements. On December 30, 2009, EPA proposed revisions to the lead monitoring requirements. As part of the proposed revisions, EPA proposed requiring monitoring near general aviation airports estimated to have lead emissions of 0.50 tons per year or greater. After the proposal was published, EPA completed a study of ambient lead concentrations near a general aviation airport which may be referenced by the EPA in preparing the final lead monitoring requirements. In addition, a final report on one of the studies relied on in the proposed rule has become available. This action announces the availability of these two studies in the Revision to Lead Ambient Air Monitoring Requirements docket (EPA-HQ-OAR-2006-0735).

SUMMARY: The EPA issued a final rule on November 12, 2008, (effective date January 12, 2009) that revised the primary and secondary National Ambient Air Quality Standards (NAAQS) for lead and associated monitoring requirements. On December 30, 2009, EPA proposed revisions to the lead monitoring requirements. As part of the proposed revisions, EPA proposed requiring monitoring near general aviation airports estimated to have lead emissions of 0.50 tons per year or greater. After the proposal was published, EPA completed a study of ambient lead concentrations near a general aviation airport which may be referenced by the EPA in preparing the final lead monitoring requirements. In addition, a final report on one of the studies relied on in the proposed rule has become available.
