Air Quality Criteria for Carbon Monoxide

AGENCY: Environmental Protection Agency.

ACTION: Call for information.

-----------------------------------------------------------------------

SUMMARY: The National Center for Environmental Assessment, of the U.S. 
Environmental Protection Agency (EPA), is undertaking to update and 
revise, where appropriate, the EPA's Air Quality Criteria for Carbon 
Monoxide (CO) as required under sections 108 and 109 of the Clean Air 
Act.
    Since completion of the 1991 criteria document for carbon monoxide, 
the EPA has continued to follow the scientific literature and compile 
information that may be relevant to the next periodic review of the 
National Ambient Air Quality Standards for CO (CO NAAQS). Interested 
parties are invited to assist the EPA in developing and refining its 
scientific information base to help ensure that all relevant 
information is considered in updating the Air Quality Criteria for CO. 
Identification of new information in the following areas will be 
particularly useful: effects of exposure on laboratory animals and 
humans; effects on the global climate; chemistry and physics; sources 
and emissions; transformation and transport in the environment; and 
ambient concentrations.
    To be considered for inclusion in the criteria document and in the 
next periodic review of the CO NAAQS, submitted information should have 
been published, accepted for publication, or presented at a public 
scientific meeting.

DATES: All communications and information should be submitted by 
December 31, 1997.

ADDRESSES: Communications should be addressed to the Project Manager 
for CO, National Center for Environmental Assessment (MD-52), U.S. 
Environmental Protection Agency, Research Triangle Park, NC 27711.

Environmental Assessment (MD-52), U.S. Environmental Protection Agency,
