Nutrient Assessment and Reduction Plan

All of the wastewater treatment plants in the Lower Des Plaines River Watershed have a requirement to complete a Nutrient Assessment and Reduction Plan (NARP) as a condition of the NPDES Permit. All but one of the treatment plants in the watershed is a member and will be working together on the development of a joint NARP by December 31, 2023.  

The Lower Des Plaines Watershed Group is coordinating the development of the NARP. As this program is under development, we will share information as it becomes available. At this time, we envision the NARP being comprised of several components that will be based on information gathered through the Bioassessment Program, the Expanded Dissolved Oxygen Monitoring and working with the DuPage River Salt Creek Workgroup and the Lower DuPage River Watershed Coalition on efforts to address nonpoint sources of nutrient pollution. The plan will have recommended action items and an implementation schedule.
