Storm Water Management Documents

The Engineering Services Department creates a variety of different reports on storm water management issues and activities. The Department is also involved in several organizations and committees that deal with the numerous storm water challenges the Village is facing.

Storm Water Management Program Development & Funding Study

In 2005 and 2006 the Village, utilizing an engineering consulting firm, performed a study to evaluate its existing Storm Water Management Program and provide recommendations on how to comply with the new National Pollutant Discharge Elimination System (NPDES) regulations. The study also identified the costs associated with administering our Program and the different methods used to fund the Program. This Storm Water Management Program study formed the basis for the Village's program that is in operation today.

National Pollutant Discharge Elimination System (NPDES) - Municipal Separate Storm Sewer System (MS4) Permit

The Illinois Environmental Protect Agency (IEPA) requires that the Village address pollution from storm water runoff through its Storm Water Management Program. The Village must identify those best management practices (BMPs) it will utilize within the six minimum control measures required by the NPDES MS4 Permit. Starting in 2003, and continuing every five years thereafter, the Village is required to submit a Notice of Intent (NOI) to the IEPA that identifies and describes the BMPs the Village will implement.

In 2018 the Village joined 40 other municipalities and townships in a partnership with DuPage County (Resolution No. 3010) to participate in their Countywide Water Quality Program. Participation allows the Village and County to work together to meet water quality goals, reducing the past duplication of efforts and saving taxpayer money. Included within this partnership, the Illinois Environmental Protection Agency granted DuPage County Stormwater Management a countywide permit to meet federal water quality requirements

In addition to DuPage County's Stormwater Management Program Plan, the Village-specific Stormwater Management Program Plan provides additional detail and defines responsibilities for each BMP at the Village level.

NPDES MS4 Permit - Annual Reports

The Village is required to submit, as well as publish for public viewing, annual reports to the IEPA as required under our NPDES MS4 Permit. These annual reports document the Village's progress towards implementing the BMPs that were identified under the six minimum control measures in the NOI.

Starting with the 2021-22 NPDES Annual Report, the Village will no longer be posting to its website and it will instead be available on DuPage County's website.

Total Maximum Daily Loads (TMDLs)

All water bodies receive pollutants storm water runoff, atmospheric deposition, waste water treatment plants, industrial discharges, natural influences and other sources. However, when the amount of pollution reaches a certain level it adversely effects the water chemistry, natural habitat and aquatic animal life. TMDLs are limits placed on streams to protect them from receiving too much pollution. On the West Branch of the DuPage River, which Carol Stream is tributary to, the IEPA has enacted a TMDL for chloride and are studying other pollutants of concern for future TMDLs including fecal coliform, dissolved oxygen, pH, silver, and manganese. The Village is a member and active participant in the DuPage River/Salt Creek Workgroup (DRSCW) which is a collection of stakeholders that have been working together to reduce storm water pollution throughout DuPage County.

DuPage County Stormwater Management Water Quality Campaign

In an effort to engage the local community in preserving and enhancing DuPage County waterways, the DuPage County Stormwater Management Division has launched a water quality campaign on Facebook and Twitter titled "Love Blue. Live Green." Please support healthy waterways in DuPage County by liking them on Facebook and following them on Twitter.
