Discussion:
As part of the Clean Water Act, the city is required to permit through the Minnesota Pollution Control Agency (MPCA) under the National Pollutant Discharge Elimination System through the Municipal Separate Storm Sewer Systems (MS4) program, which requires us to prepare, manage, and maintain a Storm Water Pollution Prevention Program. A requirement of our current permit that was approved in 2014 by the MPCA was to update the city's ordinances to meet certain minimum conditions pertaining to post-construction storm water management (e.g. surface water resources management ordinances).This update was required to be completed by 2015.
On March 9, 2017, the MPCA performed an MS4 audit on the City of Shakopee. From this audit, the MPCA identified a violation for the failure to include certain surface water and erosion control measures to ensure proper implementation and enforcement conditions within the city's regulatory mechanism.
The city's regulatory mechanism includes City Code Chapter 54 Water Resources Management and the city's Design Criteria, which includes the technical provisions and design standards. In accordance with the MPCA requirements, City Code Chapter 54 and the Design Criteria have been revised to meet the requirements of the MS4 general permit.
