HELENA – The Montana Department of Environmental Quality is seeking public comment on three reports regarding the industrial wastewater facilities at the Colstrip Steam Electric Station. The reports are required under the Administrative Order on Consent between DEQ and Talen Montana, LLC at Colstrip, which provides a mandatory procedure for investigation and remediation related to the wastewater facilities.
The reports DEQ is seeking comment on are:
- Colstrip Wastewater Facility Closure Plan, Plant Site
- Colstrip Wastewater Facility Closure Plan, Units 1&2 Stage I & II Evaporation Pond Site
