Stormwater Quality Assessment

This report documents the findings of a study conducted to determine the total suspended solids (TSS) reduction achieved by the Village of Belleville’s existing storm infrastructure and street sweeping program, and identify alternatives for achieving additional TSS reductions. Communities with a municipal separate storm sewer system (MS4) regulated by a Municipal Wisconsin Pollutant Discharge Elimination System (WPDES) Permit are required to achieve a 20% reduction in total suspended solids in runoff that enters waters of the state as compared to no controls by 2008, and a 40% reduction by March 10, 2013.

It has been suggested by the WDNR that communities located within the Rock River Basin TMDL area should also meet these requirements. The Village of Belleville is not a WPDES regulated MS4, nor is it located within the Rock River TMDL; therefore it is not required to meet either of these standards at this time.

However, as the Village is spending millions of dollars to dredge and restore Lake Belle View, it is in their best interest to keep as much sediment as possible from reaching the lake, both to protect their investment and to preserve the economic and social benefits of being lake community.
