COEUR D'ALENE, Idaho — With our pleasant early spring weather, construction season is well underway in the Silver Valley. The Coeur d’Alene Trust (CDA Trust), under the direction of the Environmental Protection Agency, has several projects taking place in the Coeur d’Alene Basin this season. In the Upper and Lower basins, cleanup work will continue to address contamination, reduce exposure to people and wildlife and improve water quality.

All Ninemile Creek basin priority cleanups were completed in 2024. Mine waste from the completed cleanup projects was deposited in the East Fork Ninemile Waste Consolidation Area (WCA). Construction of the final cover system for the WCA will begin in 2025 and will be complete in 2026.

Cleanup work continues at the Star Complex near the community of Burk
