Honorable Christine Todd Whitman
Administrator
U.S. Environmental Protection Agency

Washington, DC 20460

              Subj ect:      Notification of a Consultation on the Agency' s Plans for a Cumulative
                           Risk Framework.

Dear Governor Whitman:

       The Executive Committee (EC) of the EPA Science Advisory Board (SAB) met on July 17-18,
2001 in the EPA Laboratory in Cincinnati, OH, in part to conduct a consultation with staff from the
Risk Assessment Forum (RAF) on the Agency's plans for a Cumulative Risk Framework.

       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 the opportunity of continuing to interact with EPA on this issue in the future.

                                   Sincerely,

                                         /S/

                                  Dr. William Glaze, Chair
                                  EPA Science Advisory Board
