Three-year cleanup targets Summit County’s Pennsylvania Mine — Summit Daily News

From the Summit Daily News via The Denver Post:

About 8 miles east of Keystone and a couple of miles south of the 14,000-foot-plus Grays and Torreys peaks, the abandoned Pennsylvania Mine is considered the worst mine in the state. The mine adds toxic heavy metal concentrations and acidifies water flowing into the Peru Creek, a tributary of the Snake River, which feeds Dillon Reservoir.

A three-year, $3 million cleanup project aims to stop that pollution. The project could serve as a model for future mine reclamation efforts around the state, said Paul Peronard, on-scene coordinator for the U.S. Environmental Protection Agency. The collaborative effort is currently under budget and ahead of schedule, he said, even with the added cost of helping Summit County fix the part of Montezuma Road that washed away in early June.

“This is very much a huge partnership,” said Jeff Graves, senior project manager with the Colorado Division of Reclamation, Mining and Safety.

For decades, government agencies and other interested parties faced issues of liability and funding when trying to tackle the mine’s cleanup.

“It’s quite a conundrum,” said Lane Wyatt, a water-quality expert with the Northwest Colorado Council of Governments. “The problem is you don’t really have anybody to point your finger to in places like this to say, ‘You’re responsible. You got to go clean this up.’ ”

This year the state is working to place one of two bulkheads, or giant concrete plugs, about 500 feet inside the mine. The bulkheads will block water from leaving through one large entry and stop water from flowing freely through the mine, Graves said.
