Tsai Creek Extended Line Lowering

Telkwa Forest Service Road, British Columbia

When stream migration exposed a section of pipeline, it put operations and supply at risk. A new buried section was installed, and the exposed portion removed, requiring a creek diversion. Atna took the lead on environmental planning, securing permits, and overseeing water quality, fish salvage, and reclamation to ensure a smooth and compliant process.
