Montana Ground Water Pollution Control System (MGWPCS) Permitting Process
The Ground Water Program of the Water Pollution Bureau administers a program that issues Montana Ground Water Pollution Control System (MGWPCS) permits to the owners or operators of potential sources of pollution to state ground waters. The current list of permittees includes operations such as custom metal ore milling companies, petroleum distribution companies, soil remediation facilities, and agricultural producers. The structures from which waste materials are discharged include tailings ponds, waste treatment and storage ponds, spill clean-up systems, and soil treatment cells that potentially discharge to ground water.
