The Animas River Stakeholders Group made its way downstream Tuesday, holding its first meeting in Durango in almost two years.
The decision to hold the group’s monthly meeting at the La Plata County Administrative Building was directly related to the Aug. 5 Gold King Mine spill that has drawn a renewed interest to the mine waste pollution occurring in the Upper Animas watershed.
Peter Butler, one of the coordinators of the group, said it’s now important to weigh the risks of managing a one-time major blowout as opposed to continuous metal loading. He said the ARSG is aware of four other major blowouts in the last 20 years, but preventing such an event can become very complicated. Sites at risk can be hard to identify, because sometimes a mine entrance can appear stable, and a collapse can occur further back in the workings, triggering a blowout.
In the aftermath of the Gold King spill, several departments compiled a preliminary “midnight list” for Gov. John Hickenlooper, identifying the most at-risk mine sites. Of the 230 potential risk sites statewide, 44 are located in the Upper Animas mining district.
But even with those sites identified, the question then becomes what method do you use to prevent such an event, and how much money are you going to spend? Stakeholders also called into question whether efforts should be directed toward continual acid mine drainage, which has longer-lasting impacts on the environment.
“People are focused on a blowout, but when you start talking about what physically you can do about it, it becomes a hard issue,” Butler said. “I’m trying to put that a little bit to the side so we can focus on continuous flow.”
Doug Jamison with the Colorado Department of Public Health and Environment said he is in support of a Superfund, but he said the Environmental Protection Agency and the state health department are offering the designation as only a potential solution. As in past meetings, officials for the two agencies were unable to answer specific questions related to site boundaries, timelines and the promise of funding – stressing the need for more data.
“It’s not a quick process,” Jamison said. “But I will say we’ve gotten better over the years.”
