TSM Performance 

The results of the 2024 self-assessment of the Graymont Quebec quicklime plants closely follow the results of the third-party assessment conducted in 2023.  The Water Stewardship as well as the Safety and Health Protocols are the areas both sites perform best. 

The Biodiversity Conservation Management Protocol requires the most improvement. Graymont’s assessed sites have been operating for at least a century. Latest site expansion has followed the most up-to-date management practices regarding biodiversity, but legacy areas have yet to include a comprehensive biodiversity management program. Nevertheless, identified species with conservation statuses are managed accordingly at all sites. 

There is no reporting for the Tailing Management Protocol as Graymont’s operations do not involve the production of mine tailings.
