1. MS4 Program Information

Stream in a Open Field

The MS4 Program is designed to address the unique challenges associated with managing stormwater runoff within urbanized areas. By implementing a comprehensive set of measures known as Minimum Control Measures (MCMs) and developing a Pollution Reduction Plan (PRP), the Township aims to minimize the impact of stormwater pollution on local water bodies, safeguard public health, and promote environmental sustainability.

History of the MS4 Program
The nationwide MS4 Program was established as part of the amendments to the Clean Water Act to help regulate stormwater discharges from municipal separate storm sewer systems. Lower Swatara Township, like many municipalities across the United States, was designated as an MS4 permittee by the Pennsylvania Department of Environmental Protection (PA DEP) and the Environmental Protection Agency (EPA). Being an urbanized area, we experience increased stormwater volume and pollutant loads due to impervious surfaces such as roads, parking lots, and rooftops. These pollutants, including sediment, nutrients, chemicals, and debris, can degrade water quality, harm aquatic life, and pose risks to public health. By implementing the MS4 Program, the Township fulfills its regulatory obligations and demonstrates its commitment to protecting the environment and enhancing the quality of life for its residents.
