Subject: Notification of a Consultation on the Draft Drinking
Water Criteria Documents for Chlorine and for
Chloramines
Dear Mr. Reilly:
The Drinking Water Committee (DWG) of the Science Advisory Board (SAB)
met on April 13-14, 1992 to discuss the Agency's March 1992 external review draft
documents: 1) Drinking Water Criteria Document for Chlorine, Hypochlorous Acid
and Hypochlorite Ion, and 2) Drinking Water Criteria Document for Chloramines.
These documents were prepared to provide the health effects basis to be
considered in establishing maximum contaminant level goals (MCLG's).
Although the discussion was originally planned to be a review of the two
draft documents, the Agency Staff did not prepare a charge to the Committee nor
did they ask the Comim-cec to respond to any specific questions. As the
discussion evolved, it became evident to the Committee that both draft documents
were still very preliminary and that further effort would be required on the part
of the Agency before the documents were ready for a full review. Consequently,
we decided to consider the discussion at the public meeting to be a Consultation
on the progress of the two documents. As you know, 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.
-------
We believe that the Consultation achieved its goal by discussing a number of
important issues that EPA can consider in revising the two draft documents. As
is our customary practice there will be no formal report fr^m the SAB as result of
this Consultation, nor do we expect any formal response f/om the Agency. We
look forward to advising the Agency in the future by consultations as well as
through more formal scientific reviews.
We appreciate the opportunity to interact with Agency Staff on these two
draft documents and look forward to conducting a formal review in the future.
Sincerely,
Dr. Ramond C. Loehr, Chair Dr. Verne A. Ray, Chair
Science Advisory Board Drinking Water Committee
