Public Participation and Involvement
Illinois Environmental Protection Agency (IEPA) Permit No. ILR40, General NPDES Permit for Discharges from Small Municipal Separate Storm Sewer Systems (PDF) offers numerous opportunities for public involvement and participation. Two areas where the public is able to learn more about DuPage County's compliance with ILR40 are listed below.
DuPage County's Construction Site Stormwater Control Activities
Stormwater discharges associated with industrial activity from construction sites that will result in the disturbance of one or more acres total land area or from construction sites less than one acre of total land that is part of a larger common plan of development or sale if the larger common plan will ultimately disturb one or more acres total land area require compliance with IEPA Permit No. ILR10, General NPDES Permit for Storm Water Discharges from Construction Site Activities (PDF). DuPage County submits a Notice of Intent (NOI) to IEPA in order to obtain coverage under ILR10 for projects where coverage is required. Additional information regarding DuPage County's construction site projects and associated stormwater discharges can be found here.
ILR40 Annual Reports
ILR40 requires DuPage County to submit an annual report to the IEPA by the first day of June each year that the permit is in effect. Each report, which covers the period from March of the previous year through March of the current year, should include the following; the status of compliance with permit conditions, an assessment of the appropriateness of identified best management practices and progress toward achieving the statutory goal of reducing the discharge of pollutants to the maximum extent practicable (MEP), identified measurable goals for each of the minimum control measures, and results of information collected and analyzed. The most recent annual report, as well as past reports, can be viewed by accessing the Water Quality Archives webpage.
