An Assessment of Potential Mining Impacts on Salmon Ecosystems of 
Bristol Bay, Alaska--Peer Review Panel Members and Charge Questions

AGENCY: Environmental Protection Agency (EPA).

[[Page 33214]]

ACTION: Notice of availability and public comment period.

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

SUMMARY: EPA is announcing the peer review panel members assembled by 
an independent contractor to evaluate the draft document titled, ``An 
Assessment of Potential Mining Impacts on Salmon Ecosystems of Bristol 
Bay, Alaska'' (EPA-910-R-12-004a-c). EPA is also announcing a three 
week public comment period for the draft charge questions to be 
provided to the peer review panel. The assessment was prepared by the 
U.S. EPA's Region 10 Office (Pacific Northwest and Alaska), EPA's 
Office of Water, and EPA's Office of Research and Development. The U.S. 
EPA conducted this assessment to determine the significance of Bristol 
Bay's ecological resources and evaluate the potential impacts of large-
scale mining on these resources.

DATES: The public comment period begins June 5, 2012, and ends June 26, 
2012. Comments should be in writing and must be received by EPA by June 
26, 2012.
    Availability: Draft charge questions are provided below. Copies of 
the draft charge questions are also available via the Internet on the 
EPA Region 10 Bristol Bay Web site at www.epa.gov/bristolbay. The draft 
document ``An Assessment of Potential Mining Impacts on Salmon 
Ecosystems of Bristol Bay, Alaska'' is also available on the Internet 
on the EPA Region 10 Bristol Bay Web site at www.epa.gov/bristolbay. A 
limited number of paper copies of the draft charge questions are 
available from the Information Management Team, NCEA; telephone: 703-
347-8561; facsimile: 703-347-8691. If you are requesting a paper copy, 
please provide your name, your mailing address, and title, ``Peer 
Review Charge Questions on An Assessment of Potential Mining Impacts on 
Salmon Ecosystems of Bristol Bay, Alaska.''
    Comments on the draft charge questions may be submitted 
electronically via www.regulations.gov, by email, by mail, by 
facsimile, or by hand delivery/courier. Please follow the detailed 
instructions provided in the SUPPLEMENTARY INFORMATION section of this 
notice.

SUPPLEMENTARY INFORMATION: 

I. Information About the Project

    The U.S. EPA conducted this assessment to determine the 
significance of Bristol Bay's ecological resources and evaluate the 
potential impacts of large-scale mining on these resources. The U.S. 
EPA will use the results of this assessment to inform the consideration 
of options consistent with its role under the Clean Water Act. The 
assessment is intended to provide a scientific and technical foundation 
for future decision making. The Web site that describes the project is 
www.epa.gov/bristolbay.
    EPA released the draft assessment for the purposes of public 
comment and peer review on May 18, 2012. Consistent with guidelines for 
the peer review of highly influential scientific assessments, EPA asked 
a contractor (Versar, Inc.) to assemble a panel of experts to evaluate 
the draft report. Versar evaluated the 86 candidates nominated during a 
previous public comment period (February 24, 2012 to March 16, 2012) 
and sought other experts to complete this peer review panel. The twelve 
peer review panel members are as follows:

    Mr. David Atkins, Watershed Environmental, LLC.--Expertise in 
mining and hydrology.
    Mr. Steve Buckley, WHPacific/NANA Alaska--Expertise in mining 
and seismology.
    Dr. Courtney Carothers--Expertise in indigenous Alaskan 
cultures.
    Dr. Dennis Dauble, Washington State University--Expertise in 
fisheries biology and wildlife ecology.
    Dr. Gordon Reeves, USDA Pacific NW Research Station--Expertise 
in fisheries biology and aquatic biology.
    Dr. Charles Slaughter, University of Idaho--Expertise in 
hydrology.
    Dr. John Stednick, Colorado State University--Expertise in 
hydrology and biogeochemistry.
    Dr. Roy Stein, Ohio State University--Expertise in fisheries and 
aquatic biology.
    Dr. William Stubblefield, Oregon State University--Expertise in 
aquatic biology and ecotoxicology.
    Dr. Dirk van Zyl, University of British Columbia--Expertise in 
mining and biogeochemistry.
    Dr. Phyllis Weber Scannel--Expertise in aquatic ecology and 
ecotoxicology.
    Dr. Paul Whitney--Expertise in wildlife ecology and 
ecotoxicology.

    The peer review panel will be provided with draft charge questions 
to guide their evaluation of the draft assessment. These draft charge 
questions are designed to focus reviewers on specific aspects of the 
report. EPA is seeking comments from the public on the draft charge 
questions and welcome input on additional charge questions consistent 
with the objectives of the assessment. The draft charge questions are 
as follows:
    (1) The assessment brought together information to characterize the 
ecological, geological, and cultural resources of the Nushagak and 
Kvichak watersheds. Was this characterization accurate? Was any 
significant literature missed that would be useful to complete this 
characterization?
    (2) A formal mine plan or application is not available for the 
porphyry copper deposits in the Bristol Bay watershed. EPA developed a 
hypothetical mine scenario for its risk assessment. Given the type and 
location of copper deposits in the watershed, was this hypothetical 
mine scenario realistic? Has EPA appropriately bounded the magnitude of 
potential mine activities with the minimum and maximum mine sizes used 
in the scenario? Is there significant literature not referenced that 
would be useful to refine the mine scenario?
    (3) EPA assumed two potential modes for mining operations: A no-
failure mode of operation and a mode outlining one or more types of 
failures. The no-failure operation mode assumes best practical 
engineering and mitigation practices are in place and in optimal 
operating condition. Is the no-failure mode of operation adequately 
described? Is the choice of engineering and mitigation practices 
reasonable and consistent with current practices?
    (4) Are the potential risks to salmonid fish due to habitat loss 
and modification and water quantity/quality changes appropriately 
characterized and described for the no-failure mode of operation? Does 
the assessment appropriately describe the risks to salmonid fish due to 
operation of a transportation corridor under the no-failure mode of 
operation?
    (5) Do the failures outlined in the assessment reasonably represent 
potential system failures that could occur at a mine of the type and 
size outlined in the mine scenario? Is there a significant type of 
failure that is not described? Are the assumed risks of failures 
appropriate?
    (6) Does the assessment appropriately characterize risks to 
salmonid fish due to a potential failure of water and leachate 
collection and treatment from the mine site? If not, what suggestions 
do you have for improving this part of the assessment?
    (7) Does the assessment appropriately characterize risks to 
salmonid fish due to culvert failures along the transportation 
corridor? If not, what suggestions do you have for improving this part 
of the assessment?

[[Page 33215]]

    (8) Does the assessment appropriately characterize risks to 
salmonid fish due to pipeline failures? If not, what suggestions do you 
have for improving this part of the assessment?
    (9) Does the assessment appropriately characterize risks to 
salmonid fish due to a potential tailings dam failure? If not, what 
suggestions do you have for improving this part of the assessment?
    (10) Does the assessment appropriately characterize risks to 
wildlife and human cultures due to risks to fish? If not, what 
suggestions do you have for improving this part of the assessment?
    (11) Does the assessment appropriately describe the potential for 
cumulative risk from multiple mines?
    (12) Does the assessment identify the uncertainties and limitations 
associated with the mine scenario and the identified risks?
    The preferred method to submit comments on the draft peer review 
charge is through the docket, which is described below. This docket is 
separate from the docket collecting public comments on the draft 
assessment itself. The EPA will evaluate comments received on these 
draft charge questions. Charge questions will be finalized and provided 
to EPA's independent contractor, Versar, Inc., who will convene the 
expert panel for independent external peer review.
    The external peer review panel meeting is scheduled to be held in 
Anchorage, AK on August 7, 8, and 9, 2012. The public will be invited 
to attend on August 7 and 8, 2012. Further information regarding the 
external peer review panel meeting will be announced at a later date in 
the Federal Register.
