On March 16, 2017, the Minnesota Pollution Control Agency issued a National Pollutant Discharge Elimination System (NPDES) General Permit to the City of Bayport for stormwater discharges from a small Municipal Separate Storm Sewer System (MS4). This permit requires the city to comply with all requirements of the NPDES General Permit.
Stormwater Pollution Prevention Plan (SWPPP)
The result of this permit is a plan called the Stormwater Pollution Prevention Plan (SWPPP). The SWPPP consists of all related documents that are required within the permit. The overall plan is designed to minimize the discharge of pollutants, protect water quality, and satisfy the appropriate water quality requirements of the Clean Water Act. The SWPPP will work towards the management, operation, and maintenance of the storm sewer system and areas the city controls that discharge to the storm sewer system in a manner to minimize the discharge of pollutants.
The SWPPP consists of a combination of best management practices (BMPs) and standard operating procedures (SOPs) including education, maintenance, control techniques, system design and engineering methods, and such provisions as determined to be appropriate. The primary goal of the SWPPP is to restore and maintain the chemical, physical, and biological integrity of waters within the city through management and treatment of urban storm water runoff. The purpose is to maintain water quality standards where there is compliance and help bring waters that do not meet water quality standards into attainment.
