ACTION: Notice of public comment period. SUMMARY: EPA is announcing a 60-day 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). 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 (https:// www.epa.gov/owow/wetlands/guidance/ mining.html). Both documents will be reviewed by an independent review panel convened by EPA’s Science Advisory Board (SAB). The SAB’s peer review meeting, which the public will be able to attend as observers, will be scheduled at a later date, and announced in the Federal Register. The public comment period and the SAB meeting are separate processes that provide opportunities for all interested parties to comment on the document. EPA intends to forward the public comments that are submitted, in accordance with this notice, to the SAB review panel prior to the meeting for their consideration. When finalizing the draft documents, EPA intends to consider any significant public comments that it receives in accordance with this notice. EPA is releasing these draft documents for the purpose of pre- VerDate Nov<24>2008 17:58 Apr 09, 2010 Jkt 220001 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 https:// www.epa.gov/ncea. DATES: The 60-day public comment period begins April 12, 2010, and ends June 11, 2010. Technical comments should be in writing and must be received by EPA by June 11, 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 the National Center for Environmental Assessment’s home page under the Recent Additions and Publications menus at https:// www.epa.gov/ncea. A limited number of paper copies are available, contact the EPA; telephone: 703–347–8629; facsimile: 703–347–8691. If you are requesting a paper copy, please provide your name, your 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 https:// www.regulations.gov, by mail, by facsimile, or by hand delivery/courier. Please follow the detailed instructions provided in the SUPPLEMENTARY INFORMATION section of this notice. FOR FURTHER INFORMATION CONTACT: For information on submitting comments to the docket, please contact the Office of Environmental Information Docket; telephone: 202–566–1752; facsimile: 202–566–1753; or e-mail: ORD.Docket@epa.gov. For technical information, please leave a message at 703–347–8629 or send e-mail to MTMCond@epa.gov. SUPPLEMENTARY INFORMATION: I. Background The purpose of the first draft report entitled ‘‘The Effects of Mountaintop Mines and Valley Fills on Aquatic Ecosystems of the Central Appalachian Coalfields,’’ is to assess the state of the PO 00000 Frm 00031 Fmt 4703 Sfmt 4703 18499 science on the ecological impacts of Mountaintop Mining and Valley Fill (MTM–VF) operations on streams in the Central Appalachian Coal Basin. This basin covers about 12 million acres in West Virginia, Kentucky, Virginia, and Tennessee. The draft report reviews literature relevant to evaluating five potential consequences of MTM–VF operations: (1) Impacts on headwater streams; (2) impacts on downstream water quality; (3) impacts on stream ecosystems; (4) the cumulative impacts of multiple mining operations; and (5) effectiveness of mining reclamation and mitigation. The impacts of MTM–VF operations on cultural and aesthetic resources are not included in the review. EPA used two primary sources of information for the evaluation: (1) The peer reviewed, published literature and (2) the Programmatic Environmental Impact Statement (PEIS) on Mountaintop Mining/Valley Fills in Appalachia and its associated appendices prepared in draft in 2003 and finalized in 2005. The second draft report entitled, ‘‘A Field-based Aquatic Life Benchmark for Conductivity in Central Appalachian Streams,’’ uses field data to derive an aquatic life benchmark for conductivity. Conductivity is a measurement of the salt content of water. The saltier the water, the more it will conduct electricity. This benchmark value may be applied to waters in the Appalachian Region that are near neutral or mildly alkaline in their pH and are influenced by salts of sulfate and bicarbonate. This benchmark is intended to protect the biological integrity of waters in the region. It is derived by a method modeled on the U.S. EPA’s standard methodology for deriving water quality criteria. In particular, the methodology was adapted for use of field data. Field data were used because sufficient and appropriate laboratory data were not available and because high quality field data were available to relate conductivity to effects on biotic communities. This draft report provides scientific evidence for a conductivity benchmark in a specific region rather than for the entire United States. II.

I. Background

    The purpose of the first draft report entitled ``The Effects of 
Mountaintop Mines and Valley Fills on Aquatic Ecosystems of the Central 
Appalachian Coalfields,'' is to assess the state of the science on the 
ecological impacts of Mountaintop Mining and Valley Fill (MTM-VF)

covers about 12 million acres in West Virginia, Kentucky, Virginia, and 
Tennessee. The draft report reviews literature relevant to evaluating 
five potential consequences of MTM-VF operations: (1) Impacts on 
headwater streams; (2) impacts on downstream water quality; (3) impacts 
on stream ecosystems; (4) the cumulative impacts of multiple mining 
operations; and (5) effectiveness of mining reclamation and mitigation. 
The impacts of MTM-VF operations on cultural and aesthetic resources 
are not included in the review. EPA used two primary sources of 
information for the evaluation: (1) The peer reviewed, published 
literature and (2) the Programmatic Environmental Impact Statement 
(PEIS) on Mountaintop Mining/Valley Fills in Appalachia and its

    The second draft report entitled, ``A Field-based Aquatic Life

is a measurement of the salt content of water. The saltier the water,
