              Subject:       Notification of a Consultation on Technologically Enhanced
                           Naturally Occurring Radioactive Materials (TENORM)

Dear Ms. Browner:

       The Radiation Advisory Committee (RAC) of the Science Advisory Board (SAB), met on
March 26, 1999 to conduct a consultation with staff from the Office of Radiation and Indoor Air
(ORIA) on data collection efforts to respond to the National Academy of Sciences (NAS),
National Research Council (NRC) recommendations on Technologically Enhanced Naturally
Occurring Radioactive Materials (TENORM), and to comment on ORIA's approach to respond
to the SAB/RAC's 1994 review of ORIA's draft scoping report on NORM (EPA-SAB-RAC-94-
013). This activity is a logical follow-up by the ORIA staff to the on-going work of the National
Research Council's report entitled Evaluation Guidelines for Exposures to Technologically
Enhanced Naturally Occurring Radioactive Materials, which addresses the potential hazards of
human exposure to TENORM.

       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 the
RAC finds the schedule appropriate, the Committee looks forward to conducting a formal review
in the future as outlined in the Development Schedule.

                                        Sincerely,
       /signed/                                       /signed/
Dr. Joan M. Daisey, Chair                        Dr. Stephen L. Brown, Chair
