Storm Water Program

Storm Water Pollution Prevention Plan (SWPPP)

Under state and federal rules, the City of New Ulm has been classified as a Municipal Separate Storm Sewer System (MS4) community. As such, the City must develop, implement and enforce a Storm Water Pollution Prevention Plan (SWPPP) that is designed to minimize the discharge of pollutants from its storm sewer system in order to protect the water quality of the receiving waters in accordance with the Federal Clean Water Act (CWA) and its amendments.

This Storm Water Pollution Prevention Plan is a local plan that has been prepared with the purpose of meeting the requirements of the Federal National Pollutant Discharge Elimination System (NPDES) Phase II permit. It is also intended to lay out the steps required to implement the phosphorous Total Maximum Daily Load (TMDL) requirements for the Minnesota River.

Best Management Practices

Best Management Practices (BMPs) are to be used to meet the minimum requirements of the NPDES Phase II permit. Those practices include:

  • Education
  • Engineering methods
  • Maintenance
  • Pollution control techniques
  • System designs
  • As well as local provisions deemed appropriate

Minimum Control Measures 5-Year Plan

The City's 5-year plan to meet each of the six Minimum Control Measures (MCM) described by the permit. The tasks described are not one-time efforts; they will continue throughout the permit period and beyond to maintain water quality. They are:

  • Construction site runoff control
  • Illicit discharge, detection, and elimination
  • Pollution prevention/good housekeeping
  • Post-construction site runoff control
  • Public education and outreach
  • Public participation/involvement
