Environmental Effects Monitoring

Catalyst’s British Columbia mills participate in the federal government’s Environmental Effects Monitoring (EEM) program, which focuses on the impacts of mill emissions to water. It involves a rolling cycle of study design, field testing, and reporting, providing important insights on the health of aquatic ecosystems and the effectiveness of regulatory protection.

Studies include precise assessments of how mill discharges affect the life cycles of fish and other marine species at all locations, and additional site-specific surveys and testing as local circumstances require. Community input has helped inform the content and scope of EEM studies

In 2011 – due to a demonstrated lack of environment impacts – Crofton was authorized to move from a three- to a six-year EEM cycle. Powell River is already on a six-year cycle, but expanded the scope of its 2012 studies to ensure they are capturing any impacts from larger cooling water discharges resulting from increased green energy production.

Findings over five EEM cycles have shown improved marine conditions – such as a downward trend in dioxin and furan concentrations – which can often be linked to specific operational changes.
