Superfund management team lays out plans for 2016

Mining-related sites along Mineral Creek, Cement Creek and the Upper Animas River are to be included in the Bonita Peak Mining District Superfund site.

Environmental Protection Agency officials say by next month they intend to provide La Plata and San Juan counties a list of tasks it expects to complete in 2016 at the proposed Bonita Peak Mining District Superfund site.

“Next month, we could provide a more comprehensive briefing on 2016 activities, where we will collect data and figure out what questions that data will answer,” Superfund project manager Rebecca Thomas said in a brief meeting with Durango city councilors and La Plata County commissioners Thursday afternoon.

The rest of the year includes plans for a hydrology study to evaluate risks to human health and water quality as well as an evaluation of historic and cultural resources in the area.

Thomas said the sampling will answer the question of which mining sites, if any, can be quickly remedied and removed from the National Priorities List, such as those contributing to Mineral Creek, which is less complex than the areas surrounding the Upper Animas River and Cement Creek.

Thursday’s meeting was largely a repeat of information from the EPA, though local officials had questions and comments about the process.

“There are a lot of people in Durango concerned it could happen again,” City Councilor Sweetie Marbury said, referring to the EPA-triggered Gold King Mine spill on Aug. 5 that ejected 3 million gallons of metal-laden water into regional watersheds.

“How will you identify the risk areas to prevent another spill happening?”

Thomas said one of the leading priorities for the Superfund team will be to examine draining adits to assess their structural stability.

Thomas said the EPA is deciding whether to expand the Gold King Mine treatment facility to treat other nearby drainage sources.

The Bonita Peak Mining District near Silverton contains 48 mine-related sites and was recommended for placement on the Federal Register for Superfund designation on April 7. The EPA now seeks comments from the public, which can be submitted online at the EPA Superfund Program Bonita Peak Mining District page.

The Superfund managerial team will return for updates the week of May 23.
