We invite you to comment on the draft state waste discharge water quality permit for Specialty Minerals in Longview.
- Specialty Minerals makes a product called precipitated calcium carbonate. It sends its wastewater to the nearby Nippon Dynawave pulp and paper mill.
- The mill then sends (discharges) treated wastewater to the Columbia River.
