JUNEAU, Alaska — The public comment period is scheduled to end next week on a federal study of large mining impacts in the Bristol Bay region.
The U.S. Environmental Protection Agency has set May 31 as the deadline for comments on its revised watershed assessment. The report also is expected to undergo a new round of peer review before a final report is released.
The final report, expected later this year, could affect permitting decisions for the proposed Pebble Mine.
The revised assessment found construction of a large-scale mine near the headwaters of Bristol Bay could have major impacts even without a mishap, including wiping out up to 90 miles of streams and altering stream flows.
The CEO of the group behind the mine project has called the EPA assessment flawed and unnecessary.
