Kennecott manages environmental impacts through concurrent reclamation

Project is improving environmental performance and the aesthetics of east facing historic waste rock piles

South Jordan, Utah (June 22, 2018) – Rio Tinto Kennecott continues advancing reclamation of waste rock piles on the lower-outer face of the Bingham Canyon Mine as part of the Alternative View Project. The project will enhance the aesthetics of historic waste rock dumps visible from the Salt Lake Valley and provide optionality for future mining.

Kennecott has spent $150 million on the project since it began in 2015. As part of the project, Kennecott has moved approximately 350 million tons of waste rock to reshape, regrade and seed 400 acres. Kennecott has also finished constructing 35 stormwater detention basins to manage surface water runoff from the mine’s face. Each of these basins is designed to manage a 100-year, 24-hour rain event.

“This is an important project because it provides environmental benefits and helps meet our community’s expectations,” said senior project manager, Zeb Kenyon. “Concurrent reclamation will continue to be an important part of our environmental commitment as we mine in the future.”

Kennecott has a 25-year history investing in concurrent reclamation, or reclaiming land that is no longer needed for the operation while mining continues. As part of that history, Kennecott has restored more than 11,500 acres of land impacted by historic mining operations and spent more than $500 million in reclamation and remediation efforts.
