             Subject; Science Advisory Board Notification of a Consultation on
             the Office of Solid Waste and En?isrgency Response's draft study
             on Superfrod site Populations at. Risk.

Dear Mr. Reilly:

       On April 7, 1992, the Environmental Health Committee (EEC) of the Science
Advisory Board (SAB) met with staff of the Office of Solid Waste and Emergency Response
and conducted a consultation on EPA's approach to estimating population risks from
hazardous waste sites.  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 provisions of the Federal Advisory Committee Act, which
includes advance notice of the public meeting in the Federal Register.  A response to this
consultation from the Agency is not solicited.

       We believe that this consultation achieved its goal by identifying several important
issues that EPA could consider in developing its risk estimates. As is our customary practice,
this consultation does not constitute a  formal report from the SAB.  However, individual
members of the panel  may provide comments, or the Committee may provide more guidance
at a later date in a Commentary or through a formal review.

-------
      We look forward to advising the Agency in the future by consultations as well as
through more formal scientific reviews.

                                      Sincerely,
                                      Arthur C. Upton, Chair
                                      Environmental Health Committee
                                               Loehr,
                                      Science Advisory Board
