SUPPLEMENTARY INFORMATION: The U.S. Environmental Protection Agency 
(EPA) is updating and revising, where appropriate, the EPA's Air 
Quality Criteria for Carbon Monoxide (CO). Sections 108 and 109 of the 
Clean Air Act require that the EPA carry out a periodic review and 
revision, where appropriate, of the criteria and the National Ambient 
Air Quality Standards (NAAQS) for the ``criteria'' air pollutants such 
as carbon monoxide.
    After the completion of the comment period for the first external 
review draft, announced in the Federal Register on March 17, 1999 (64 
FR 13198), and that draft's review by the Clean Air Scientific Advisory 
Committee (CASAC) in June 1999, the EPA revised the draft Air Quality 
Criteria for Carbon Monoxide. The Agency is now issuing a second 
external review draft for a thirty-day public comment period and for 
review before CASAC later in 1999. There will be a subsequent Federal 
Register notice to inform the public of the exact date and time of that 
CASAC meeting.

    Dated: October 7, 1999.
William H. Farland,
Director, National Center for Environmental Assessment.
