Ensuring Sustainable Stormwater Management for a Cleaner Environment

Municipal Separate Storm Sewer Systems (MS4) play a crucial role in managing stormwater runoff to protect our water bodies from pollution. At Engineering Management, Inc. (EMI), we specialize in providing comprehensive MS4 engineering and compliance services designed to meet the stringent requirements set by the Environmental Protection Agency (EPA) and state regulators.

What is MS4?

An MS4 is a conveyance system, including roads with drainage, storm drains, curbs, gutters, ditches, man-made channels, or storm sewers, owned by a municipality. Unlike combined sewer systems, MS4s are designed to transport only stormwater, not sewage. However, stormwater often picks up pollutants as it flows over streets, parking lots, and other surfaces, making MS4s a critical component in preventing water pollution.

Our MS4 Services

At EMI, we offer a full range of MS4 services, including:

• Stormwater Pollution Prevention Plans (SWPPP): We develop and implement SWPPPs that identify potential sources of pollution and outline measures to reduce stormwater contamination.

• Illicit Discharge Detection and Elimination (IDDE): Our team identifies and mitigates illicit discharges, ensuring that only stormwater enters the MS4.

• Public Education and Outreach: We design programs to educate the community about the importance of stormwater management and encourage responsible practices.

• Mapping and Inventory: Using the latest GIS technology, we create detailed maps of MS4 infrastructure, helping municipalities manage their systems effectively.

• Compliance Audits and Reporting: EMI conducts thorough audits and prepares required reports to ensure your MS4 program meets all regulatory obligations.
