Improvements to Swiftcurrent Sewage System and the Many Glacier Wastewater Treatment Plant Environmental Assessment

Enclosed is Glacier National Park's Environmental Assessment (EA) for the Many Glacier/Swiftcurrent Sewage System and Wastewater Treatment Improvements for public review and comment. Both the sewage and treatment systems are over 30 years old and are showing signs of deterioration. In addition, the Many Glacier wastewater treatment plant does not currently have a Montana Department of Environmental Quality (MDEQ) discharge permit. The park proposes to replace or rehabilitate parts of the sewage and treatment system to meet the standards for a permit.
Two alternatives are analyzed: a No Action Alternative which would maintain the current sewage system conditions and a Preferred Alternative. The Preferred Alternative is to: replace or re-line the sewer pipes coming from the Swiftcurrent developed area and the force mains from both the Swiftcurrent and Many Glacier Districts, upgrade the Swiftcurrent lift station, and make several improvements to the control building, headworks, lagoon, percolation ponds, and fencing at the wastewater treatment plant.
The resources that would be affected by the alternatives are Archeological Resources, Soils, Wildlife, Special Status Species, Water Quality, and Park Operations.
