       Subject:      Clean Air Scientific Advisory Committee Teleconference Consultation on
                    the Agency '$ Project Work Plan for Revised Air Quality Criteria for
                    Ozone and Related Photochemical Oxidants

Dear Governor Whitman:

       The Clean Air Scientific Advisory Committee (CAS AC) of the EPA Science Advisory
Board (SAB) met via public teleconference  on February 6, 2003, to conduct a Consultation with
staff from EP A's National Center for Environmental Assessment (NCEA), Office of Research
and Development (ORD), on EPA-NCEA's Project Work Plan for Revised Air Quality Criteria
for Ozone and Related Photochemical Oxidants.

       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 (FACA), as amended (5 U.S.C.
App.), 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 CASAC or the SAB
as a  result of this Consultation, nor do we expect any formal response from the Agency.

                                       Sincerely,

                                             /Signed/
                                       Dr. Philip K. Hopke, Chair
                                       Clean Air Scientific Advisory Committee
