STANNARD TWP STP - Secondary Wastewater Treatment in Stannard Township, Michigan

STANNARD TWP STP is a municipal wastewater treatment facility located in Stannard Township, Ontonagon County, Michigan. The plant serves a small population of 741 residents and operates under secondary treatment standards, which is the minimum required by the US Clean Water Act for domestic wastewater. As a small-scale facility, it plays a crucial role in protecting local water quality in this rural area of Michigan's Upper Peninsula. The plant has a designed capacity of 340.69 volume units and discharges a similar volume of treated wastewater. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The facility is subject to National Pollutant Discharge Elimination System (NPDES) permitting under the Clean Water Act, administered by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). The treated effluent from STANNARD TWP STP ultimately drains into the Lake Superior watershed, the largest of the Great Lakes. The plant's location more than 10 km from the coast but within 50 km means its discharge contributes to the broader Lake Superior ecosystem. Protecting this watershed is vital for maintaining water quality in the Great Lakes, which support diverse aquatic life and provide drinking water for millions.

The plant discharges into the Lake Superior basin, part of the Great Lakes system. Lake Superior is the largest freshwater lake by surface area and supports a sensitive ecosystem including lake trout, whitefish, and migratory birds. The watershed is characterized by forested terrain and cold, clear waters. Protecting this environment from nutrient pollution and pathogens is critical, as the lake has low nutrient levels naturally and is vulnerable to eutrophication from excess phosphorus.
