Water Quality | Draft Environmental Assessment for the Construction and Operation of Subsurface Wastewater Treatment Systems | Comment Period Ends 05-01-2026
Under the Montana Environmental Policy Act (MEPA) (75-1-102, Montana Code Annotated (MCA)), Montana agencies are required to prepare environmental review for state actions that may have an impact on the Montana environment. The proposed action—issuing a certificate of subdivision approval or letter of approval to construct and operate a subsurface wastewater treatment system (SWTS)—is considered to be a state action that may have an impact on the Montana environment. Therefore, the Department of Environmental Quality (DEQ) must prepare an environmental assessment (EA).
