             Subject: Notification of a Consultation on Bioaccumulation Issues

Dear Ms. Browner:

       The Joint Bioaccumulation Subcommittee of the Ecological Processes and Effects
Committee and the Drinking Water Committee of the Science Advisory Board (SAB) met on
April 28-29, 1994, to conduct a consultation with staff from the Office of Water on the Agency's
proposed strategy for deriving bioaccumulation values for lipophilic compounds. The
consultation was held in conjunction with a formal review of the Thomann Food Web Model.
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
Subcommittee will issue a formal report with regard to the Thomann model.

                                 Sincerely,

                                       /signed
