Subject: Notification of a Consultation on the Diesel Health Assessment
Dear Ms. Browner:
The Clean Air Scientific Advisory Committee (CASAC) of the Science Advisory Board
(SAB), met on June 9-10, 1999 to review and/or consult on several issues. During the meeting,
the Committee conducted a Consultation with staff from the Office of Research and
Development (ORD) on ORD's plans to revise the Diesel Health Assessment. The plans for the
revision were based, in part, on earlier comments from the Committee from its May 1998 review
meeting.
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, the
Committee looks forward to conducting a formal review of the revised Diesel Health Assessment
in FY2000.
Sincerely,
Dr. Joe Mauderly, Chair
Clean Air Scientific Advisory Committee
