ENVIRONMENTAL PROTECTION AGENCY
[FRL-8244-1; EPA-HQ-Docket ID No. EPA-ORD-2006-0939]

Draft Toxicological Reviews of Cyanobacterial Toxins: Anatoxin-a,
Cylindrospermopsin and Microcystins LR, RR, YR and LA

AGENCY: Environmental Protection Agency.
ACTION: Notice of public comment period and external peer-review panel
meeting.

-----------------------------------------------------------------------

SUMMARY: The U.S. Environmental Protection Agency (EPA) is announcing a
forty-five day public comment period and an external peer-review panel
meeting to review the external review draft documents entitled,
``Toxicological Reviews of Cyanobacterial Toxins: Anatoxin-a,
Cylindrospermopsin and Microcystins LR, RR, YR and LA'' (NCEA-C-1743,
NCEA-C-1763 and NCEA-C-1765). Cyanobacteria, commonly referred to as
blue-green algae, are found in freshwater, estuarine and marine
environments. Cyanobacteria, other freshwater algae, and their toxins
are included as microbial contaminants on EPA's Office of Water (OW)
Contaminant Candidate List (CCL). These draft assessments discuss
potential human health effects of exposure to these cyanobacterial
toxins for four durations--acute, short-term, subchronic and chronic--
focusing on noncancer effects due to oral exposure.
    The public comment period and the external peer review are separate
processes that provide opportunities for all interested parties to
comment on these documents. These documents were prepared by EPA's
National Center for Environmental Assessment (NCEA) within EPA's Office
of Research and Development. EPA will use comments and recommendations
from the public and the expert panel meeting to finalize the draft
documents. EPA is releasing these draft documents solely for the
purpose of pre-dissemination peer review under applicable information
quality guidelines. These documents have not been formally disseminated
by EPA. They do not represent and should not be construed to represent
any Agency policy or determination.

DATES: The public comment period will begin on November 20, 2006 and
continue until January 4, 2007. The public may submit comments via
Regulations.gov (see SUPPLEMENTARY INFORMATION below). The peer-review
panel meeting will begin on January 10, 2007, at 9 a.m. and will end at
5 p.m.

The public may attend the peer-review panel meeting and are invited to

information refer to the instructions for registration below).

ADDRESSES: Eastern Research Group, Inc., an EPA contractor for external
scientific peer review, will convene an independent panel of experts
and organize and conduct an external peer-review panel meeting to
review these draft documents. The external peer-review panel meeting
will be held at EPA's Andrew W. Breidenbach Environmental Research
Center (AWBERC) located at 26 W. Martin Luther King Drive, Cincinnati,
OH. Observers may attend the peer review meeting by filling out the
