March 16, 1999 EPA-SAB-EEC-CON-99-003 Honorable Carol M. Browner Administrator U.S. Environmental Protection Agency 401 M Street, SW Washington, DC 20460 Subject: Notification of a Consultation on the Advantages and Disadvantages of Average or "Not to Exceed" Concentrations in the Development of Cleanup Goals at Waste Sites. Dear Ms. Browner: The Statistical Consultation Subcommittee of the Environmental Engineering Committee (EEC) of the Science Advisory Board (SAB), met on March 16, 1999 to conduct a consultation with staff from the Office of Solid Waste and Emergency Response (OSWER) on the Advantages and Disadvantages of Average or "Not to Exceed" Concentrations in the Development of Cleanup Goals at 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 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. Sincerely, /s/ /signed/ Dr. John P.
