Stormwater Management
National Pollutant Discharge Elimination System (NPDES)
The goal of the federally mandated National Pollutant Discharge Elimination System (NPDES) Phase II program is to preserve, protect and improve the Nation’s water resources from polluted stormwater runoff. NPDES Phase II is intended to reduce adverse impacts to water quality and aquatic habitat by instituting the use of controls on the unregulated sources of stormwater discharges that have the greatest likelihood of causing continued environmental impact. NPDES Phase II requires operators of Municipal Separate Storm Sewer Systems (MS4s) in urbanized areas to implement Best Management Practices (BMPs) defined in six minimum control measures to control polluted stormwater runoff. For questions or concerns about the Village’s NPDES program please contact the Public Works Department at (815) 877-5432.

Concrete Washouts
The residue and contaminants from washing concrete trucks, pumps, mixers, chutes, hand tools, and wheelbarrows is called “concrete washout”. Products like grout, mortar and stucco and activities such as saw cutting, coring, grinding and grooving can also result in concrete washout. This type of waste is highly alkaline, contains high levels of chromium, and is corrosive. When not managed properly concrete washout can pollute surface water and groundwater by changing its pH, increasing the toxicity of other substances, and reducing water clarity.
Management Tips
Why Care About Clean Water?
Stormwater pollution is one of the greatest threats to Machesney Park’s creeks and rivers. Clean water means safe drinking water, places for recreation and healthy wildlife habitats. Rain washes pollution from streets, parking lots and lawns into storm sewers and drainage ditches then directly to our streams, rivers and ultimately, the ocean. By taking steps such as using proper concrete washout facilities we can insure that we protect these assets.
OVERVIEW
Stormwater runoff is generated when precipitation from rain and snow-melt events flows over land or impervious surfaces and does not percolate into the ground. As the runoff flows over the land or impervious surfaces (paved streets, parking lots, and building rooftops), it accumulates debris, chemicals, sediment or other pollutants that could adversely affect water quality if the runoff is discharged untreated.
The primary method to control stormwater discharges is the use of best management practices (BMPs). In addition, most stormwater discharges are considered point sources and require coverage under an NPDES permit.

MS4 Information Guide
Erosion and Sediment Control
What is Erosion and Sediment Control?
The Village of Machesney Park holds a permit with The Illinois Environmental Protection Agency which requires us to manage the quality of storm water which leaves the Village limits and protect the environment by monitoring pollution in our local storm water system. The Village has a Municipal Separate Storm Sewer System (MS4) which means that rain water that falls in our area runs directly into the Rock River. During a rain storm, exposed soil can wash away and into the local waterways. As a result, preventative measures must be taken to stop soil erosion and keep the Rock River clean.
Why is Erosion and Sediment Control So Important?
Soil erosion and sedimentation are major contributors to pollution in our waterways. When rain falls on exposed soil, it washes soil away from the land. Runoff erodes bare ground, washes away valuble topsoil, and makes landscaping more difficult. It also carries nutrients, sediment, and other pollutants into streets, gutters, and ditches, where it then travels untreated to lakes, rivers, streams, or wetlands. Polluted runoff causes excessive growth of lake weeds, algae blooms, and reduced recreational opportunities such as swimming and fishing. Sediment-laden runoff clogs pipes, ponds, lakes and wetlands and increases the risk of flooding.
Homeowner’s Guide to Erosion and Sediment Control
This guidebook has been provided by The Village of Machesney Park to help residents who wish to self perform work that requires erosion and sediment control measures. The guidebook can be used as a starting point for designing an erosion and sediment control system for your particular project and also gives information on how to install and maintain common types of best management practices (BMPs).
Illinois Department of Transportation (IDOT) – Field Guide to Erosion and Sediment Control
This guide is published by the Illinois Department of Transportation and provides information on how to properly select, install, and maintain erosion control best management practices. It may be useful to refer to this guide during weekly inspections as this guide was originally intended for use by IDOT inspectors checking contractor’s for compliance.
USEPA Guide to Writing a Storm Water Pollution Prevention Plan (SWPPP)
This manual on creating a SWPPP is published by the United State Environmental Protection Agency and can be very helpful in creating an effective plan to minimize storm water pollution on construction sites. Please be aware that this manual can be somewhat technical in nature.

Management Tips
- Do not dump concrete washout on the ground or allow it to enter storm drains, open ditches, streets and waterways.
- Washout facilities should only be for chute and tools washing. Truck washout and remaining concrete should be taken back to the plant.
- Washouts should be large enough to contain liquid and concrete waste generated by washout operations.
- Keep washout areas a minimum of 50 feet from storm drains, open ditches and water bodies and install signs for locating the washout.
- Washout facilities must be cleaned or new facilities constructed and ready for use, one the washout container is 75% full.
- Under no circumstances should a washout facility be allowed to overflow.
