Supplementary Information

I. Information About the Project/Document

The U.S. Environmental Protection Agency (EPA) conducted this assessment to provide a characterization of the biological and mineral resources of the Bristol Bay watershed, increase understanding of the potential impacts of large-scale mining on the region's fish resources, and inform future governmental decisions.

A previous draft was released for public comment on May 18, 2012 (77 FR 31353, May 25, 2012). Peer review panel members were announced June 5, 2012 (77 FR 33213, June 5, 2012), and the external peer review meeting was announced July 6, 2012 (77 FR 40037, July 6, 2012). The external peer review meeting was held in Anchorage, AK, August 7-9, 2012. This revised draft was completed by the agency to address public and peer review comments provided on the May 2012 draft.

EPA is releasing this revised draft assessment for the purposes of public comment. This draft assessment is not final as described in EPA's information quality guidelines, and it does not represent and should not be construed to represent Agency policy or views.

EPA is seeking comments from the public on all aspects of the report, including the scientific and technical information presented in the report, the realistic mining scenario used, the data and information used to inform assumptions about mining activities and the evaluations of risk to the fishery, and the potential mitigation measures considered (and effectiveness of those measures). EPA is also specifically seeking any additional data or scientific or technical information about Bristol Bay resources or large-scale mining that should be considered in our evaluation. EPA will consider any public comments submitted in accordance with this notice when revising the document.
