Butterfield and Sentinel Quarry Expansion

Document Description: The project is the proposed expansion of Omya's Butterfield and Sentinel Limestone Quarries. The project includes expansion of existing Butterfield and Sentinel quarries, expansion of associated overburden placement sites, additional internal access roads and ancillary facility areas. The project does not include any new quarries, new haul roads or new overburden sites. The proposed expansion would include 30.6 acres of new disturbance at the Butterfield Quarry, and 64.3 acres of new disturbance at the Sentinel Quarry area (94.9 total area of new disturbance). The expansion would add an additional 40-years life to the Butterfield quarry and an additional 20-years life to the Sentinel Quarry.
