One state agency has fined another for work performed on the 2010 replacement of the Highway 95 bridge in Princeton.
The Minnesota Department of Transportation and its contractors have been fined $13,750 by the Minnesota Pollution Control Agency for stormwater violations that resulted in erosion along the Rum River as well as stormwater with heavy sediment entering the river.
The violations occurred during the 2010 reconstruction of the bridges at Highway 95 and Rum River Drive. The Rum River in this area is listed by the MPCA as a scenic and recreational waterway. These specially designated waterways have more stringent standards under which they are governed, MPCA officials said.
According to MPCA staff inspection reports, the construction site lacked sufficient sediment and erosion controls. Because these kinds of structures, or best management practices, were not properly in place, erosion occurred and sediment-laden stormwater was allowed to enter the Rum River during construction.
The violations were discovered during inspections between July and November 2010. In addition to paying a $13,750 penalty, MnDOT and its contractors have stabilized the site so it is again in compliance with stormwater rules and regulations.
