The Effects of Mountaintop Mines and Valley Fills on Aquatic
Ecosystems of the Central Appalachian Coalfields and a Field-Based
Aquatic Life Benchmark for Conductivity in Central Appalachian Streams
AGENCY: Environmental Protection Agency (EPA).
ACTION: Extension of public comment period to September 3, 2010.
-----------------------------------------------------------------------
SUMMARY: EPA is announcing an extension of the public comment period
for two related draft documents: (1) ``The Effects of Mountaintop Mines
and Valley Fills on Aquatic Ecosystems of the Central Appalachian
Coalfields'' (EPA/600/R-09/138A) and (2) ``A Field-based Aquatic Life
Benchmark for Conductivity in Central Appalachian Streams'' (EPA/600/R-
10/023A). We are specifically extending the comment period on these two
documents to give the public additional time to evaluate the data used
to derive a benchmark for conductivity. The original Federal Register
notice announcing the public comment period was published on April 12,
2010 (75 FR 18499). By following the link below, reviewers may download
the initial data and EPA's derivative data sets that were used to
calculate the conductivity benchmark. These reports were developed by
the National Center for Environmental Assessment (NCEA) within EPA's
Office of Research and Development as part of a set of actions taken by
EPA to further clarify and strengthen environmental permitting
requirements for Appalachian mountaintop removal and other surface coal
mining projects, in coordination with Federal and State regulatory
agencies (http://www.epa.gov/owow/wetlands/guidance/mining.html).
Both documents were reviewed by an independent Mountaintop Mining
Advisory Panel convened by EPA's Science Advisory Board (SAB) on July
21--23, 2010. The public comment period for the SAB meeting follows a
separate process and provides separate opportunities for all interested
parties to comment on the document. EPA intends to forward to the SAB
those comments received as of September 3, 2010, for consideration by
the SAB Panel as they finalize their report. When finalizing the draft
documents, EPA will consider the comments from the SAB review as well
as any significant public comments that it receives in accordance with
this notice.
EPA released these draft documents for the purpose of pre-
dissemination peer review under applicable information quality
guidelines. The documents have not been formally disseminated by EPA.
They do not represent and should not be construed to represent a final
Agency policy or determination; however, the documents reflect EPA's
best interpretation of the available science. The draft documents are
available via the Internet on NCEA's home page under the Recent
Additions and Publications menus at http://www.epa.gov/ncea.
DATES: The public comment period began on April 12, 2010, and ends on
September 3, 2010. Technical comments should be in writing and must be
received by EPA by September 3, 2010.
ADDRESSES: The draft reports, ``The Effects of Mountaintop Mines and
Valley Fills on Aquatic Ecosystems of the Central Appalachian
Coalfields'' and ``A Field-based Aquatic Life Benchmark for
Conductivity in Central Appalachian Streams'' are available primarily
via the Internet on NCEA's home page under the Recent Additions and
Publications menus at http://www.epa.gov/ncea. A limited number of
paper copies are available; contact the EPA by telephone (703-347-8629)
or facsimile (703-347-8691). If you are requesting a paper copy, please
provide your name, mailing address, and the document titles (1) ``The
Effects of Mountaintop Mines and Valley Fills on Aquatic Ecosystems of
the Central Appalachian Coalfields'' and (2) ``A Field-based Aquatic
Life Benchmark for Conductivity in Central Appalachian Streams.''
Comments may be submitted electronically via http://www.regulations.gov, by mail, by facsimile, or by hand delivery/
courier. Please follow the detailed instructions provided in the
SUPPLEMENTARY INFORMATION section of Federal Register Notice (75 FR
30393).
