Water Quality Trading Plan
2/20/2024
The Village of Soldiers Grove plans to utilize Water Quality Trading(WQT) for compliance with the final total phosphorus limit as provided in the Wisconsin Pollutant Discharge Elimination 4263a8788c76406e25fea0e0a0778a08WPDES) Permit #WI-0022241-10-0. The Wastewater Treatment Facility(WWTF) treated 0.0300 MGD with an average effluent Total Phosphorus(TP) concentration of 4.92 mg/L in 2023. The Village plans to install chemical addition for Total Phosphorus treatment at the WWTF and will offset remaining TP with WQT Credits to consistently meet the final annual six-month average limit of 0.1 mg/L and a monthly average limit of 0.3 mg/L. NRCS Streambank Erosion modeling methods were used to calculate the TP credits that will be generated from the streambank stabilization project.
Public & Safety Benefits –
- streambank stabilization for homes located along Baker Creek Road
- streambank stabilization for Village Shop and Soldiers Grove Fire Department Building located along Legion Drive
- improved public access to Baker Creek for fishing and recreation
- increased hydraulic retention within the project area for flood mitigation
Environmental Impacts -

- Will minimize erosion of the steep, heavily eroded streambanks
- Will improve riparian filter strip
- Will reduce Total Suspended Solids, Total Phosphorus, and other pollutants/nutrients entering the stream
- No fill shall be deposited within the flood plain or wetland areas
- Required permits will be acquired for construction
