Upper Blackfoot Mine Complex: DEQ to hold public meeting on 2018 construction season

HELENA – The Montana Department of Environmental Quality will give a presentation on the 2018 construction season at the Upper Blackfoot Mining Complex (UBMC) at the regular meeting of the Lincoln Community Council on Tuesday, June 19, at 6:30 p.m. The meeting will be at the Lewis & Clark Library - Lincoln Branch, at 102 9th Ave S., Lincoln, Mont.


DEQ officials will give an overview of the work plan, followed by a question-and-answer session for the public. Community members are encouraged to attend to learn what’s next at the site.


DEQ will begin the next phase of work at UBMC this summer, starting at the confluence of Mike Horse and Beartrap Creeks and moving down to the Water Treatment Plant. Work may then continue from the Water Treatment Plant toward Edith Mine, dependent upon achieving project milestones set in the bid package. Crews are expected to remove up to 269,000 cubic yards of waste. That’s in addition to approximately 700,000 cubic yards of tailings and mine waste removed since excavations began in 2014.


DEQ has released bid solicitations for this phase of work and construction is expected to begin in July. DEQ aims to finish this work by the end of the 2019 construction season.

What: Public presentation to the Lincoln Community Council on the Upper Blackfoot Mining Complex
When: Tuesday, June 19, 6:30 p.m.
Where: Lewis & Clark Library – Lincoln Branch, 102 9th Ave S., Lincoln, Mont.

About the Upper Blackfoot Mine Complex

The Upper Blackfoot Mining Complex is a State Superfund facility located about 15 miles east of Lincoln. Seeps from the tailings and waste rock dumps along with acid mine drainage from old adits have contaminated surface water, sediment, soils and groundwater. Additional contamination exists due to the 1975 dam failure that washed metals-laden tailings down the Beartrap Creek drainage and into the upper Blackfoot River.


DEQ has led cleanup efforts in coordination with USFS and NRDP over the past several years. The primary goal of the cleanup is to remove approximately 1 million cubic yards of tailings and mine waste to protect human health and the environment.
