About the Wide Area Remediation Plan
Teck has developed a Wide Area Remediation Plan for the Lower Columbia River valley, which sets out measures to address impacts related to historical air emissions from the smelter in Trail. The WARP incorporates a recommendation from a Medical Health Officer that will guide remediation measures for lead (Pb).

Teck has made significant improvements over the decades to reduce emissions, achieving a 99.5% reduction in lead (Pb) stack emissions since 1997. However, historical emissions have affected soils in areas of the Lower Columbia River valley, posing potential risks to human health and the environment.
The WARP formalizes Teck’s commitment to addressing these impacts and developing a strategy that complies with provincial regulations.
Engagement
Teck initiated engagement with Indigenous communities in May 2024, and public engagement took place in January 2025. The materials available below were developed for public engagement to provide a high-level overview of the WARP and supporting technical documents to help people provide feedback. Feedback provided during engagement on the WARP was reviewed by Teck and the Medical Health Officer and the WARP and supporting documents were updated where appropriate.

Current Status
The updated WARP and supporting technical documents were submitted to the BC Ministry of Environment and Parks in June 2025 for review and approval. The BC Ministry of Environment and Parks is currently reviewing the documents and has initiated Indigenous consultation on the approval decision. A final decision on the WARP is anticipated mid-2026.
