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.
