             Subject:      Notification of a Consultation on the Development of the Carbon
                          Monoxide Staff Paper

Dear Ms. Browner:

       The Clean Air Scientific Advisory Committee (CAS AC) of the Science Advisory Board
(SAB), met on November 18, 1999 to conduct a consultation with staff from the Office of Air and
Radiation (OAR), Office of Air Quality Planning and Standards (OAQPS) on the continuing
Development of the Staff Paper for the national ambient air quality standards (NAAQS) for
Carbon Monoxide.  The Committee conducted a Consultation on the Development Schedule for
this document last year.  At the November 18,  1999 meeting, the Agency staff updated the
Committee on developments in the preparation and scheduling of the draft Staff Paper.

       The SAB has developed the consultation as a mechanism to advise the Agency on
technical issues that should be considered in the development of regulations, guidelines, or
technical guidance before the Agency has taken a position.  A consultation is conducted under the
normal requirements of the Federal Advisory Committee Act, which include advance notice of the
public meeting in the Federal Register. As is our customary practice, there will be no formal
report from the SAB as a result of this consultation, nor do we expect any formal response from
the Agency.  However, since CAS AC finds the document progressing appropriately, the
Committee looks forward to conducting a formal review of the draft Staff Paper in the spring of
2000, as outlined in the Development Schedule and briefing.
                                 Sincerely,
                                        /signed/
                                 Dr. Joe Mauderly, Chair
