It was nine years ago yesterday, while I was sitting in our Durango home, when a tweet from La Plata County popped up on my screen warning residents of an upstream spill of some sort. “I gotta see this,” I said to myself, running out to the old Silver Bullet and driving it to the 32nd Street Bridge. When I found the water to be its usual placid green, brimming with SUPers and boaters and scantily-clad tubers, I continued north into the broad, flat-bottomed Animas Valley, where the generous monsoon had left pastures green and cottonwoods lush.
I turned onto Trimble Lane, passed the golf course and rows of McMansions to a little turnout by the bridge and was transfixed by the river: Turbid, electric-orange water, utterly opaque, sprawled out between the sandy banks, as iron hydroxide particles thickened within the current like psychedelic smoke.
The crazy color was the result, of course, of the Gold King Mine spill, when contractors for the EPA inadvertently breached an earthen plug in the portal of the Gold King Mine, releasing some 3 million gallons of TANG-hued, acidic, metal-tainted water into a tributary of the Animas River, turning the waterways various shades of yellow and orange for a good 100 miles downstream. The incident drew global attention, shut down the river, and affected recreation, commerce, and agriculture, as well as inflicting trauma on the collective psyches of the riverside communities — some of which still lingers today.
It really seemed, at the time, to be a turning point. After years of lurking under the public radar, abandoned mines and the ways they harm the environment, impair water quality, and sometimes harm human health were finally getting attention. There were congressional hearings on the problem, dozens of stories in the national media, and Gold King downstreamers demanded that the Upper Animas River watershed be declared a Superfund site in order to fix the problem, once and for all.
Nine years have passed, a Superfund site — the Bonita Peak Mining District — was established, numerous lawsuits have played out, and as much as $160 million has been spent responding to the initial disaster and on Superfund-related activities in the years since. And yet, no meaningful federal policy regarding abandoned mines has been passed by Congress or implemented by the White House. And while Gold King Mine discharges are being treated, keeping some harmful metals out of the streams, very little additional progress has been made on solving the larger problem of abandoned mines in the Upper Animas watershed and their effect on water quality.
It is all a bit discouraging, to say the least. Though none of it is all that surprising.
On the federal policy part, the Biden administration issued a report last summer calling for major reforms to the 1872 General Mining Law. The proposed changes would increase protections on mining claim/lease and permitting end, so as to avoid future Gold King events. And they would establish a reclamation fee and royalties on federal hardrock minerals to help fund a restoration industry tasked with cleaning up abandoned mines.
It all sounds great, but so far has yielded very little actual policy. Yes, the Biden administration increased mining claim fees from $165 to $200. And the Infrastructure Investment and Jobs Act and the Inflation Reduction Act did earmark billions of dollars for abandoned mine — and oil and gas well — cleanup. As for Congress, the closest they’ve gotten to a viable mining law reform bill is one clearing the way for corporations to use public lands as waste dumps.
The problem is that the mining industry wields a great deal of power, especially in Nevada, Arizona, and Utah. And that means that even Democratic, otherwise green-leaning politicians tend to bow down to industry (see Sens. Jacky Rosen and Catherine Cortez Masto, both of Nevada). The Biden administration, meanwhile, has developed a case of carbon tunnel vision, and is looking to streamline and encourage mining for so called “green metals” such as lithium, manganese, cobalt, and copper. And it has also signed on to efforts to bolster the domestic uranium mining industry to support a growing advanced nuclear reactor sector. Implementing the administration's own recommended reforms could slow those efforts.
As for a lack of progress in the Upper Animas? That’s a more complicated situation. In fact, it’s the complicated nature that makes it so challenging.
Superfund — or CERCLA — seems to work well as a blunt instrument for cleaning up old factories, waste dumps, or other contained industrial sites, and for holding the responsible parties to account. It has a good track record on some mining sites, as well, including several in the West. Even then, however, the cleanup can last for decades, and in the case of draining mines, may require water treatment in perpetuity.
But there’s nothing straightforward or simple about the environmental legacy of mining in the Upper Animas watershed and the 48 sites within the Bonita Peak Mining District Superfund site. The mountains’ innards resemble Swiss cheese, with miles and miles of drifts and shafts in addition to natural fractures and faults that blur hydrological understanding. Indeed, mysteries remain around the exact source and pathways of the water that blew out of the Gold King in 2015. (For what is likely the most exhaustive, and exhausting, chronological dive into the Gold King/Sunnyside/American Tunnel connections, check out this old Land Desk wonkfest. But remember, only paid subscribers have access to the archives!)
Further complicating issues is a fair amount of natural acidity and metal loading that can never be cleaned up, along with the still unanswered question of which stretches of stream may have been able to support fish before mining commenced, and which ones may feasibly be able to support fisheries in the future. In other words, what is the end goal of the project? What would “fixing” the problem, as downstreamers demanded in 2015, look like in terms of specific water quality improvements in specific stretches of streams? And are those desired fixes feasible? Nine years later and those questions linger.

The saddest part of it all, perhaps, is the fact that those questions were being asked and answered, and solutions were being implemented, prior to the Gold King spill. The Animas River Stakeholders Group moved maddeningly slow at times, but they were thorough, realistic in what could be achieved, and effective. They were also efficient: Since their funding was limited, they had to prioritize projects that would give them the biggest water quality bang for their buck. They were also somewhat limited in what they could do thanks to liability issues. While moving or capping a waste pile is fairly low risk, if a “good samaritan” like ARSG tries to fix a draining, abandoned mine, it could become responsible for future problems — like the Gold King blowout, for example. So, ARSG relied on industry partners for draining adits, or called in the EPA.
A lot of folks, myself included, hoped that the Superfund cleanup would incorporate ARSG as an active partner and build upon their efforts. Just imagine what the group, which was formed in 1994 and included a vast storehouse of water quality data and analysis and human expertise, could have done with EPA funding and liability protection? Instead, the EPA started virtually from scratch. The ARSG ultimately disbanded and was replaced by the citizens advisory group, or CAG. Former ARSG Coordinator Peter Butler was brought on as CAG’s chair.
I’d run into Butler on occasion while running or hiking the trails around Durango, and he always seemed a bit frustrated about the lack of progress at the Superfund site and the EPA’s lack of receptiveness to the advisory group’s advice and data collection.
Shortly after the Gold King spill, the EPA had spent many millions of dollars setting up a water treatment facility in the former mining town of Gladstone, at the mouth of the bulkheaded and defunct American Tunnel (which accessed the Sunnyside, the last operating mine in the region, which was shuttered in 1991). But it only treats drainage from the Gold King, letting acid mine drainage from other nearby adits flow unmitigated into Cement Creek, which ultimately joins up with the Animas River. Other than that, the EPA had done very little in the way of substantive remediation, and downstream water quality has remained poorer than it was in the early 2000s, when the Sunnyside’s treatment plant was still up and running. (It’s a very long story, but to sum it up: Legal issues, a lack of funding, and an eviction shut treatment down in 2004, causing water quality and downstream fish populations to deteriorate).
Still, I was a bit shocked when Butler announced his resignation from the CAG late last year, and sent a letter detailing his reasons for moving on. He cited the lack of CAG influence on decision-making, the high turnover among local EPA administrators, and the EPA’s failure to honor promises made to the local community prior to Superfund designation. And, he wrote:
EPA has collected an enormous amount of information and data over the last seven years. However, the amount of metal loading in the river and streams, the impacts that it has on aquatic life, the metals of greatest concern, and the main source areas of metals and their relative importance has not significantly changed from what was known by ARSG in the early 2000’s. It doesn’t seem that work done previous to the Superfund designation has sped up the timetable at all. EPA appears to be on its typical 20-year plus timeframe for completing work at this Superfund site.
(The EPA later responded, as reported by the Durango Herald’s Reuben M. Schafir)
It was damning criticism and the EPA lost an important advisor when Butler stepped down. And while the CAG continues its work with a capable group of local advisors, Butler’s exit also seemed to signal the end of the Animas River Stakeholders Group era, in which environmentalists, bureaucrats, scientists, and industry collaborated to find working solutions to complex problems.
It has taken me a while to write about this, in part because I do find it somewhat heartbreaking. It also worries me. Earlier this year Navajo Nation advocates and residents celebrated when the EPA finally designated the Lukachukai Mountains Mining District Superfund site after years of lobbying for it. They saw it as a guarantee that dozens of abandoned, Cold War-era uranium mines would finally be cleaned up and would stop oozing toxic material into the water and homes. And maybe it is, but how long will it take?
The sad reality is that no one — not the EPA, not the Stakeholders group, not industry — will ever totally fix the problem of polluting abandoned mines in the Upper Animas watershed. All they can really do is manage it and, in an ideal world, learn from the experience and develop better and more innovative ways to carry out that management. I suppose in EPA-time, nine years isn’t all that long. There’s still time to right the ship so that the project can benefit the water and the local community.
