Vote on Climate

In my last post, I explored the origins of an alpine lake in North Cascades. The news cycle was especially terrible the day I wrote it, so I decided to leave out details about the causes and consequences of glacial retreat in North Cascades. But honestly, the causes and consequences are too great to ignore. It is no small irony that my insight and enjoyment into the formation of an alpine lake was inadvertently provided by people through human-caused climate change.

All glaciers in North Cascades are retreating and they’ve collectively lost over 50% of their mass during the last 100 years. This is directly due to a warming climate, a product of burning fossil fuels like coal and oil.

Unless you’ve been living under one of those glaciers for the past century, you might’ve heard there’s an election next week and voting has begun in many states. While casting our votes, we have an opportunity to elect representatives who will work to mitigate climate change. But, we shouldn’t vote to combat climate change just because glaciers are receding in North Cascades National Park.

We should act on climate, because glacial melt water moderates summertime drought. Millions of people depend on glaciers for drinking water.

We should act on climate to lessen the risk from extreme weather events like drought, hurricanes, floods, and heat waves.

We should act on climate to ensure supplies of fresh water are not overly taxed by humanity’s increasing demands. Who wants reliable access to clean fresh water? All of us.

We should act on climate to help reduce the spread of invasive species, many of which are finding easier footholds where ecosystems are already stressed and fragmented.

We should act on climate to prevent the loss of arctic sea ice, a habitat that helps cool the planet by reflecting sunlight into space, forms the basis of a complex polar food web, and is one necessary for the survival of polar bears.

We should act on climate so coastlines aren’t flooded by sea level rise.

We should act on climate to mitigate ocean acidification, which can impact marine food chains. A lot of us eat seafood and even if we don’t, we like animals that eat seafood (whales, bears, etc.). What would Katmai National Park, my favorite place, be without abundant salmon? An impoverished place, that’s what.

I could go on, but I think you get the point.

We have a moral responsibility to stave off the worst climate change impacts, because this is a human-caused issue. Collectively we can do it, but we have to take the threat seriously. We, as a nation, didn’t vote to combat climate change during the 2016 election. Thankfully, we have another chance now, but time is running out to slow and eventually halt what is one of the most pressing issues facing humanity. That’s why I’m voting for initiatives to mitigate climate change and only for candidates who take climate change seriously.

In Washington, Initiative 1631 would authorize the first carbon tax in the U.S. This is my ballot.

I’ve been fortunate enough in my life to explore active glacial environments in many parts of North America. In Katmai, I’ve walked on pumice-covered glaciers to reach volcanic calderas, numbed my feet in icy glacial runoff, and eaten freshly calved ice (if you’re wondering, it was clean tasting but a little gritty). In the North Cascades I explored the margins of the region’s still active ice. To find an advancing glacier in modern times, however, is rare. Melting glaciers are one of our most conspicuous symbols of global warming.

Glaciers have come and gone in the past, of course. I grew up in a region of Pennsylvania where Ice Age glaciers terminated their last advance, leaving behind eskers and sand quarries. I lived near Lake Chelan, a remarkable inland fjord carved by glaciers. Katmai was also completely overrun by ice. Modern glacial retreat is different though, because we’re the primary cause. Climate change isn’t a hoax or some deep-state conspiracy. It’s real, it’s here, and humans are causing it. There is no scientifically plausible alternative theory that explains the changes to Earth’s climate observed since the Industrial Revolution.

I still find beauty in the ice, but each time I see a glacier I also am reminded of one of Aldo Leopold’s many maxims,

“One of the penalties of an ecological education is that one lives alone in a world of wounds. An ecologist must either harden his shell and make believe that the consequences of science are none of his business, or he must be the doctor who sees the marks of death in a community that believes itself well and does not want to be told otherwise.”

The community is not well, because we’ve wounded it. Let’s step up and act. When you vote, only vote for those who take climate change seriously and, more importantly, will actively work to reduce its impact. The status quo got us here, but the status quo is no longer good enough.

Pebble Mine Scoping Comments

Recently, I wrote about an impending threat to Bristol Bay’s salmon: Pebble Mine. The mine, if developed, will have significant effects across some the richest salmon and brown bear habitat left on Earth.

Salmon remain the ecological and cultural heartbeat of Bristol Bay. This mine will create billions of tons of semi-fluid toxic waste, which must be treated and prevented from entering the watershed indefinitely. Impacts from development are never completely restricted to the development’s footprint either. Roads fragment habitat and vehicle traffic displaces wildlife.

When I was born, Pacific and Atlantic salmon fisheries in the Lower 48 states were already significantly degraded. Nearly 40 years later, many salmon stocks in New England, California, Oregon, and Washington remain threatened or endangered. Only a small fraction of fish return to these areas compared to historic levels. I’m not about to let this story repeat itself in Alaska, nor should you. If the mine is developed, future generations will inherit its legacy, and I predict they won’t look upon us fondly for repeating the same mistakes that killed salmon runs in the past.

Please comment during the scoping period on the Army Corps of Engineers’ Pebble Mine Environmental Impact Statement (EIS) and send those comments to your congressional representatives as well. Below you’ll find my scoping comments for the proposed mine. Feel free to copy and personalize them as you see fit. State your concerns now, so when the Army Corps of Engineers writes the EIS it will fully evaluate the mine’s impacts. Don’t let Bristol Bay’s salmon disappear because of our lust for copper and money.

The Corps is accepting comments through June 29, 2018.

Comment to the U.S. Army Corps of Engineers (submitted May 23, 2018):

The proposed Pebble Mine and its associated infrastructure poses a substantial threat to salmon and wildlife across the Bristol Bay region. Pebble Mine will straddle the watershed divide between two of Bristol Bay’s most important salmon spawning and rearing areas. I remain very concerned with the mine’s potential to negatively impact the area’s fisheries and wildlife through its wastewater, tailings, and infrastructure.

The EIS must answer one question: can Pebble Mine be developed without significantly degrading water quality and fisheries? The Corps’ has authority to deny permits under section 404 of the Clean Water Act if a proposed action will significantly degrade water quality and fisheries. This EIS should evaluate and quantify, not just identify, the mine’s potential to significantly degrade water quality and fisheries over short and long-term timespans. The EIS can begin this evaluation by appropriately defining its purpose.

A recent environmental impact statement from the Army Corps of Engineers, the Donlin Mine EIS, merely stated the purpose of the mine and the Corps’ authority to permit it (Donlin Mine Final Environmental Impact Statement – Chapter 1, pg. 1-4, 1-6). The purpose and need of the Pebble Mine EIS should be not be to simply define the project’s purpose (to mine ore) and define the Corps’ regulatory authority. It should be, as I propose, to:

  • Identify the short-term and long-term ecological effects of the proposed Pebble Mine,
  • Evaluate the mine’s and its infrastructure’s impacts on wildlife, including fish, in order to
  • Determine whether the mine’s safeguard can prevent all degradation to water quality, salmon habitat, and wildlife habitat indefinitely.

Even at very low concentrations, dissolved copper is particularly toxic to salmon, interfering with their ability to navigate and avoid predators. Its effects can manifest over minutes or hours and persist for weeks (Hecht 2007). Can the mine’s wastewater treatment plan adequately remove dissolved copper and prevent it from entering the watershed?

The mine’s tailings also pose a great risk to fish. Any accidental discharge from the pyritic tailings ponds will significantly degrade salmon habitat. Open pit mines, even within the United States, have a poor record containing their toxic tailings. Most tailings dam failures occur at operating mines and 39 percent of such failures worldwide occur in the United States, significantly more than in any other country (Rico 2008). Earthquakes and flooding hazards increase the risk of a tailings pond dam failure in the Bristol Bay region, and tailings ponds cannot be drained in the event of flooding or dam failure due to their toxic contents. The probability of a M8+ earthquake, for example, is low from year to year but remains real at any given time. Therefore, the EIS must also evaluate whether the tailings ponds can be engineered to withstand the greatest potential earthquakes and floods expected over the next several thousand years.

After the mine’s 20-year active phase, the mining company proposes to store toxic pyritic tailings indefinitely under water in the former open pit. This seems to create the potential for acid mine drainage to leach into the watershed over hundreds or thousands of years. What geologic studies suggest this is a feasible long-term plan to store the tailings? Even if subaqueous storage in the former open pit prevents the tailings from oxidizing, what safeguards will prevent dissolved copper and other toxic metals from entering groundwater to eventually oxidize and acidify as it nears the surface in a different part of the watershed?

The mine’s supporting infrastructure also creates risks for salmon and wildlife. Although salmon can navigate and migrate through streams with high sediment loads, they do not spawn in these habitats. Erosion of sediments into streams can irritate the gills of fish, smother eggs, alter feeding habitat for salmon fry, and bury spawning habitat. The effects of road construction and vehicle traffic (estimated by the mining partnership to be 35 round-trip truck trips per day) on wetlands and fisheries should also be evaluated.

The road servicing the proposed Amakdedori Port and the port itself will fragment what is now an unspoiled region of coastline on Cook Inlet. McNeil River State Game Sanctuary is one of the most important brown bear refuges on Earth, home to the largest annual congregation of bears yet observed. The road and port have the potential to displace bears moving to and from the McNeil River and Katmai National Preserve areas. Frequent work and dredging at the port area will also displace wildlife in an area that now experiences very little human activity. Other alternatives to transport ore should be evaluated.

Finally, the EIS needs to address more than the 20-year operational phase, because the mine’s waste legacy will threaten salmon for thousands of years. Tailings stored in the former open pit won’t become benign in the near future and wastewater must be treated indefinitely. Also, the possibility of an expanded mine operating over a long time frame increases the threat to salmon, other wildlife, and clean water.

Combined, the Nushagak and Kvichak rivers support about 40% of Bristol Bay’s sockeye salmon. In 2017 alone, over 56 million sockeye salmon returned to Bristol Bay and over 19 million returning to Nushagak River, the largest in the river’s history. Salmon fishing in Bristol Bay is a billion dollar industry. While commercial fisheries generate the bulk of the salmon’s economic value, the area’s tourism is almost entirely based on salmon as well. Bristol Bay is home to dozens of premier sport fishing destinations, which harbor abundant populations of rainbow trout, Dolly Varden, arctic char, northern pike, lake trout, and grayling. The Bristol Bay area also hosts some of the densest populations of brown bears ever measured. Salmon are the most important food source for these animals, and the vast majority of people who visit Katmai National Park come to watch brown bears (Strawn 2015). After spawning, dead salmon fertilize the ecosystem with nutrients derived from the ocean, boosting the productivity of otherwise nutrient-poor area.

Considering the overwhelming economic and ecological value of salmon to the Bristol Bay region, Pebble Mine could displace thousands of workers and tourists if its safeguards fail to protect salmon. Without the energy and nutrients provided by consistently large runs of anadromous salmon, Bristol Bay’s freshwater and terrestrial ecosystems will quickly transition from one of richness to poverty. In many ways, this cycle is a positive feedback loop. The productivity of the area is reliant on large runs of salmon.

We’ve seen, repeatedly, salmon populations in the Pacific Northwest and New England decimated by habitat loss and pollution. Now we’re on the brink of repeating the same mistake in Bristol Bay. Pebble Mine should not be developed. It’s in the greatest interest of Bristol Bay’s fishing industry and culture, watersheds, salmon, and wildlife for the Corps’ EIS to fully evaluate the mine’s near and long-term effects. A failure to contain the mine’s toxic tailings and wastewater would directly impact two of Earth’s most productive salmon producing watersheds. The EIS must address potential groundwater exchange in the abandoned open pit, and whether the mining company can eliminate the risk of acid mine drainage. It must address whether the embankments for tailings ponds can withstand high magnitude earthquakes. It must address whether it’s even appropriate to build a mine whose wastewater will need to be treated indefinitely. It also must critically evaluate the mine’s supporting infrastructure, as it will potentially disrupt the world’s largest seasonal congregation of brown bears. In sum, the EIS must evaluate a worst-case scenario for salmon and other wildlife, since the possibility can’t be completely, or even reasonably, eliminated.

The Worst Place in the World for a Mine

“This is the jewel in the crown of America’s fisheries resources – these salmon. If you don’t think this is worth saving, what is? To me, if you don’t draw a line in the sand here, there’s none to be drawn anywhere.”

Thomas Quinn
Professor, University of Washington and author of The Behavior and Ecology of Pacific Salmon and Trout

After more than a decade of controversy, Pebble Mine is inching closer to reality, and from the perspective of salmon, we couldn’t choose a worse place for an open pit mine.

If you’re unfamiliar with Bristol Bay, its salmon, or Pebble Mine, please watch this 2012 overview on the Pebble Mine controversy, keeping in mind the mine’s currently proposed size and mineral processing plans are different than those outlined in the video.

Pebble Mine is a proposed open-pit copper, gold, and molybdenum mine at the headwaters of some of the last intact and most productive salmon habitat on Earth. Before any development of the mine can begin however, it must be permitted, and before it can be permitted, it must undergo an extensive environmental review. This is where we stand currently: the environmental impact statement (EIS) process for Pebble Mine has begun.

An EIS goes through several stages before a “record of decision” is finalized. Right now, the Pebble EIS is only at the scoping level. If you’re unfamiliar with the EIS process, public scoping is basically a brainstorming step. It’s the public’s opportunity to help define the breadth of the EIS to the lead agency, which in this case is the Army Corps of Engineers. (Read more about the scoping process.) During public scoping, if people don’t express concerns for the ecosystem-wide impacts of Pebble Mine and its infrastructure then the Corps’ EIS will not address them. Therefore, we must comment during the scoping period and demand that the alternatives in the EIS address the mine’s full environmental impact—which will sprawl across southwest Alaska and threaten the last great sockeye salmon run in North America.

The Bristol Bay area is exceptionally special and unique. Its landscape remains largely undeveloped and un-engineered. The major factors that decimated salmon elsewhere—habitat loss, dams, and pollution—are absent and salmon runs reach tens of millions of fish annually. Bristol Bay is where we can imagine the richness of fish that used to flood into the Columbia River or New England. It remains home to one of the most valuable and sustainable fisheries on Earth, one of the few remaining places where the full potential of the ecosystem is realized.

The Pebble EIS must address the mine’s potential, worst-case scenario effects on Bristol Bay’s salmon. A failure to contain the mine’s toxic tailings and wastewater would directly impact two of Earth’s most productive salmon producing watersheds. (The Kvichak River watershed, where part of the mine will be located, is home to the single largest salmon run in the world.) It must address potential groundwater exchange in the abandoned open pit, and whether the mining company can eliminate the risk of acid mine drainage. It must address whether the embankments for tailings ponds can withstand high magnitude earthquakes. It must address whether it’s even appropriate to build a mine whose wastewater will need to be treated indefinitely. It also must critically evaluate the mine’s supporting infrastructure, as it will potentially disrupt the world’s largest seasonal congregation of brown bears.

Pebble Mine will straddle the divide between the Nushagak and Kvichak watersheds, two of Bristol Bay’s riches salmon producing areas.

By law, the EIS process must identify the least environmentally damaging practicable alternative. Common sense implies the least damaging alternative in this case is no mine at all, but the National Environmental Policy Act does not require agencies implement it. If we don’t demand the Corps critically evaluate the myriad impacts from the mine, then the Corps will merely focus on holes in the ground, “alternatives” of natural gas versus diesel to power the mine, how wide the service roads will be, and the size of the ports. The scope of the EIS will be so narrow to be useless for the protection of salmon. (For an idea of what this might be, look no further than the Donlin Mine Final EIS, whose purpose and need is: “produce gold from ore reserves from the Donlin deposit using mining processes, infrastructure, logistics, and energy supplies that are economical and feasible for application in remote western Alaska. The applicant’s stated need for the project is to provide economic benefits to Donlin Gold, Calista, and TKC shareholders; and to produce gold to meet worldwide demand.”)

I recognize a sad irony—or hypocrisy, if you prefer—of using a computer, which contains gold and copper, to type this post. I understand there’s a hole in the Earth, perhaps filled now with toxic water, where the metals in my machine were once trapped in rock. If you, like me, think Pebble Mine is irresponsible, then voice your opposition not only through the EIS process and with your votes at the ballot box (politicians who support Pebble Mine will not receive my vote), but also by reducing your consumption of products that use gold and copper. We, as consumers, need to say enough is enough. Our addiction to ever-higher levels of consumption brought us here. It’s not really sufficient to say “I’m opposed to Pebble Mine” then go out and buy the newest iPhone even though your old phone works just fine.

Everything we use, everything we make, has a cost. We’re at a point in history when surging human population growth and mass consumption are pushing ecosystems and species to their breaking point, creating an ecologically impoverished planet. In New England, wild Atlantic salmon are nearly extinct, and on the U.S. west coast only a tiny fraction of Pacific salmon return compared to historic levels. Don’t kid yourself: This sad story can repeat itself in Alaska.

We lose salmon one impassible culvert, one dam, one levee, one mine at a time, leaving us to suddenly wonder, where did all the fish go? In Bristol Bay we have a chance, maybe our last chance, to save large runs of wild salmon. If the mine is built and its proposed safeguards fail, we risk losing a significant portion one of the world’s last great sustainable fisheries. Future generations won’t be celebrating our decision if we develop this mine. They’ll criticize us for not learning from the mistakes of the past. Are we really willing to let hyper-consumerism and the promise of short-term profits potentially destroy the last great salmon run?

It looks like we’re on track to do so, unless enough people step up and say no.

Through June 29, 2018, you can submit scoping comments on the Pebble Mine EIS. I’ll share my scoping comments in a forthcoming post when they are finished.

Update May 23, 2018: My scoping comments can be found here.
