Stormwater Management

Stormwater Management

Stormwater Management involves implementing practices to reduce contamination of surface water runoff from rain and snowmelt. In urban and suburban areas, land is often covered by buildings and pavement, which do not allow rainwater and snow melt to enter the ground. Waters instead runoff via storm sewers, culverts, and ditches and enter nearby rivers, lakes and streams. This stormwater runoff can often carry dirt, chemicals, greases and oils, fertilizers, and other contaminants into these water bodies. management is important to protecting the water quality of these natural resources that we all enjoy.

Residents can assist with reducing stormwater pollution by ensuring activities such as home improvement projects, landscaping, car washing, application of salt and sand during winter, and many other activities are undertaken in ways that eliminate or minimize stormwater runoff. For larger activities such as construction sites and developments, there are permit requirements that must be met to help ensure water quality is protected.

This webpage provides information about local permit information, contact information, and educational resources for stormwater management in our local area.

Municipal Separate Stormwater Program (MS4)

The U.S. Environmental Protection Agency and Illinois Environmental Protection Agency (Illinois EPA) ‎‎administer a stormwater permit process under the National Pollutant Discharge Elimination System ‎‎‎(NPDES) requirements for Small Municipal Separate Storm Sewer Systems, referred to as MS4 ‎‎communities. These regulatory requirements involve addressing potential sources of stormwater ‎‎pollutants within a community.

The goal of the MS4 program is improve the quality of stormwater runoff that enter enters rivers, lakes, and streams by reducing or eliminating pollutants, such as soil erosion, greases and oils, chemicals, and other contaminants.

The Illinois EPA requires that both the City of East Dubuque and Dunleith Township meet the requirements of the MS4 program for areas within their jurisdiction. This webpage provides resources with specific program information for both the City and the Township.

MS4 General Storm Water Permit

The Illinois EPA administers the state-wide General Storm Water Permit for MS4s, which was reissued on February 10, 2016, with an effective date of March 1, 2016. The expiration date is February 28, 2021. Significant changes have been made in the permit based on comments received by the Agency. The MS4 permit is in the process of being renewed by Illinois EPA and until then MS4 communities such as East Dubuque and Dunleith Township continue to operate under the expiring MS4 permit.

More complete information on the MS4 permit program is available on the Illinois EPA website at the following link:

MS4 Permittees must file a Notice of Intent with the Illinois EPA, develop a Stormwater Management Program, and make information available to the public about the program. Links are available below for the specific documents and contact information for each community. Educational information about stormwater management is also available.
