Location & History
The Specialty Minerals, Inc. plant in Wallula manufactures precipitated calcium carbonate. This is produced by reacting carbon dioxide (CO2), from the Boise White Paper pulp and paper mill or liquid CO2, with slaked lime. Wastewater and stormwater are sent to the Boise White Paper Wallula pulp and paper mill's wastewater treatment system. The wastewater is then discharged to the Columbia River through Boise's outfall 001.
Sanitary wastewater is also sent to the Boise Wallula mill, where it is treated through an on-site septic system.
