Bristol Bay Assessment – Supplemental Peer Review Reports (May 2012)
Background
In May 2012, the U.S. Environmental Protection Agency (USEPA) released the draft assessment entitled An Assessment of Potential Mining Impacts on Salmon Ecosystems of Bristol Bay, Alaska, or the Bristol Bay Assessment. The purpose of the assessment is 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. During the public comment period for the May 2012 draft, numerous technical reports were submitted to the public docket. The USEPA identified several of these reports as providing information about issues raised by the peer reviewers, but the reports did not show evidence of prior peer review. The USEPA made arrangements for a contractor to conduct independent peer reviews of seven such reports.
The reports and the results of these supplemental peer reviews are provided here to document that the reports are of "sufficient scientific quality and credibility" to be incorporated into the second external review draft of the Bristol Bay Assessment.
