Stormwater Pollution Management at a Foundry Site
Stormwater pollution from heavy manufacturing sites is generally regulated under federal and state regulations. Neenah Foundry, Neenah, Wisconsin was found to be in violation of the state guidelines (based on USEPA benchmarks) for total suspended solids, aluminum, nitrate/nitrite, copper, and zinc concentrations. Through discussions with the Wisconsin Department of Natural Resources (WDNR), the manufacturer agreed on a course of action that included conducting event based monitoring at an outfall (recording rain and flow gauge; and automatic event sampling. A total of nine events were monitored in the fall of 2004 and spring of 2005. The monitoring data was also used to calibrate the urban pollution model: WinSLAMM (Windows Source Loading and Management Model, see www.winslamm.com). The model was used to evaluate various pollution control approaches. Based on the results of the monitoring and modeling, proprietary and non-proprietary BMPs were evaluated for the three storm sewer outfalls.
