ARRA - Madison Area Wastewater Treatment Project Environmental Assessment
The National Park Service (NPS) is proposing to replace the wastewater treatment plant at Madison Junction in Yellowstone National Park. The existing sewage treatment plant is aging and at risk of failure. A new wastewater treatment system would provide improved wastewater treatment (partial tertiary treatment) and protect park resources by preventing sewage spills, reducing odors, and improving views on the West Entrance Road.
