After a few hiccups, fits, and false starts, the EPA has finally released the Draft Bristol Bay Watershed Assessment Report.
No surprise, but as it turns out, digging a huge fucking hole in the headwaters plain of several anadromous streams isn’t really a good idea when viewed against the background of the world’s largest sockeye fishery.
Some key findings:
The rivers of Bristol Bay support the world’s largest sockeye salmon runs (46% of the “global abundance” of sockeye) and its Chinook runs are near the world’s largest every year.
All five species of North American Pacific salmon are found in Bristol Bay. The Bristol Bay watershed supports the largest sockeye salmon fishery in the world.
The Kvichak River produces more sockeye salmon than any other river in the world.
The Nushagak River is the fourth largest producer of Chinook salmon in North America.
Bristol Bay’s wild salmon fishery and other ecological resources provide at least 14,000 full and part-time jobs and is valued at about $480 million annually.
The average annual run of sockeye salmon is about 37.5 million fish.
Bristol Bay provides habitat for numerous animal species, including 35 fish species, more than 190 bird species and 40 animal species.
Aaaaaand a key excerpt:
“Based on this mine scenario, we conclude that, at a minimum, mining at this scale would cause the loss of spawning and rearing habitat for multiple species of anadromous and resident fish. A mine footprint of this scale would likely result in the direct loss of 87.5 to 141.4 km of streams and 10.2 to 17.3 km2 of wetlands. Additionally, water withdrawals for mine operations would significantly diminish habitat quality in an additional 2 to 10 km of streams. Assuming no significant accidents or failures, the development and routine operation of one large-scale mine would result in significant impacts on fish populations in streams surrounding the mine site. Accidents, process failures, and infrastructure failures could increase the spatial scale and severity of mining impacts on fish populations. Potential accidents include
(1) the release of acid, metal, and other contaminants from the mine site, waste rock piles, and tailings storage facilities (TSFs)
(2) the failure of roads, culverts, and pipelines in the transportation corridor, including spills of copper concentrate
(3) the catastrophic failure of a tailings dam.
Although precise estimates of the probabilities of failure occurrence cannot be made, evidence from the long-term operation of similar large mines suggests that, over the life span of a large mine, at least one or more accidents or failures could occur, potentially resulting in immediate, severe impacts on salmon and detrimental, long-term impacts on salmon habitat and production.”
While the EPA makes no pronouncements or decisions through this document, one fact becomes very clear in reading through the document:
Bristol Bay is the wrong place to allow industrial scale mining.
The job of convincing the Obama Administration to take action before January 20, 2013, now begins in earnest. Please take 5 minutes and fill out This Online Action Letter and ask the President to initiate the Clean Water Act process that will enable EPA to limit industrial scale mining in Bristol Bay. Ask your friends and family to do the same.
Shout outs to Trout Unlimited’s Tim Bristol and Shoren Brown for kicking more ass in a few years than most men in a lifetime. Respect to all the folks watching out for Bristol Bay, and thanks for your continued efforts.
They won’t go unnoticed, fisha.
