A -- REVIEW OF NATIONAL AMBIENT AIR QUALITY STANDARDS FOR CARBON MONOXIDE DUE 111797 POC Jim Raub, EPA Project Officer, (919)541-4157 The U.S. Environmental Protection Agency is performing a "market search" for 10-15 qualified scientists to provide support for the National Center for Environmental Assessment in Research Triangle Park, NC (NCEA-RTP). NCEA-RTP has need for contractor support to help prepare an Agency document describing the scientific basis for review and possible revision of the current National Ambient Air Quality Standards (NAAQS) for carbon monoxide (CO). A previous assessment of the scientific basis for the CO NAAQS appeared in the 1991 CO Air Quality Criteria Document (AQCD), Air Quality Criteria for Carbon Monoxide (EPA/600/8-90/045F). NCEA-RTP is seeking the professional services of scientists who have extensive knowledge of carbon monoxide and are able to provide EPA with the best available scientific evidence in support of the CO NAAQS review. Although emphasis will be placed on the presentation of health effects data, other scientific areas to be covered are the nature, sources, distribution, measurement, and concentration of CO in the environment, as well as the measurement of population exposure to CO. It is anticipated that multiple purchase orders will be issued utilizing simplified acquisition procedures in accordance with the Federal Acquisition Regulation Part 13. Each purchase order for professional services will cover a period of approximately 18-24 months and will involve the completion of several key tasks. Tasks will include: (1) authorship of a technical draft section; (2) participation in scientific peer-review meetings/conferences (travel will be required); (3) completion of one or more revisions to the technical draft section; and (4) response to comments received from the public and from the Clean Air Scientific Advisory Committee of EPA's Science Advisory Board. A Statement of Work providing more specific details of the tasks, the deliverables, and time schedules required of the contractor will be made available to qualified experts at a later date. NO REQUEST FOR QUOTATIONS WILL BE ISSUED ASA DIRECT RESULT OF THIS SYNOPSIS. Scientists with the ability to provide the professional services listed above are encouraged to respond. Please submit copies of a curriculum vitae, publication history or other written materials that describe your scientific expertise, and any evidence of previous contributions to similar assessments. Responses should also indicate willingness to travel to workshops and meetings, as needed. All information from interested scientists should be forwarded to: Project Manager, Air Quality Criteria for Carbon Monoxide, U.S. EPA, NCEA (MD-52), Research Triangle Park, NC 27711. (0302)
