Wastewater Treatment Project (West Side) Environmental Impact Statement, Glacier National Park, Montana

Under the provisions of the National Environmental Policy Act, the National Park Service is preparing an environmental impact statement for the Lake McDonald/Park Headquarters Wastewater Treatment System Rehabilitation for Glacier National Park. This statement will be approved by the Intermountain Regional Director. The existing system collects throughout the Lake McDonald/ Headquarters area via a series of gravity sewer lines and sewage lift stations and force mains. The existing wastewater treatment facility is comprised of a single cell aerated lagoon, irrigation pond, control building and spray irrigation system. At the wastewater treatment facility, raw wastewater flows to a 4.8 million gallon aerated lagoon where bacteria reduce the biological oxygen demand (BOD) and suspended solids concentration of the wastewater. The treated wastewater flows to an adjacent .5 million gallon irrigation pond where an irrigation pump takes flow from the pond to a 55 acre spray irrigation field, currently located in the 100 year floodplain of McDonald Creek. This project and EIS has been proposed to analyze alternatives for addressing these issues. The effort will result in a proposed course o
