HART STP Wastewater Treatment Plant, Hart Township, Michigan

HART STP is a municipal wastewater treatment plant located in Hart Township, Oceana County, Michigan, serving a population of about 1,950 people. The facility is situated near the eastern shore of Lake Michigan, within 50 km of the coastline, and operates under the regulatory framework of the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges to surface waters. The plant's designed capacity is 1.00 million gallons per day, reflecting its role in managing wastewater for a small community. Plants of this scale in Michigan typically employ secondary treatment to meet state and federal water quality standards. The facility is part of the municipal infrastructure that protects public health and the environment. Treated effluent from HART STP is discharged into local waterways that ultimately drain into Lake Michigan, one of the Great Lakes. Lake Michigan supports diverse aquatic life and provides drinking water for millions. The plant's location near the coast underscores the importance of effective treatment to prevent nutrient pollution and protect the lake's ecological health.

HART STP discharges into tributaries of Lake Michigan, a large freshwater lake that is part of the Great Lakes system. Lake Michigan supports a rich ecosystem, including native fish species and migratory birds. The plant's proximity to the coast means that treated effluent must meet stringent nutrient limits to prevent algal blooms and maintain water quality in this ecologically sensitive region.
