What is Mn/DOT Metro District doing in the Stormwater Pollution Prevention Program (SWPPP)?

Below is a summary of activities planned for each of the six minimum control measures:

1. Public education and outreach

• Develop and distribute educational materials to inform citizens about the impacts polluted stormwater runoff can have on water quality.
• Form partnerships with other MS4’s to more effectively distribute public educational materials.
• Incorporate new and updated educational materials/information into existing program.

2. Public Involvement                           

• Provide opportunity for public participation and comments through our Annual Meeting and the feedback link on this MS4 Website.

3. Illicit Discharge Detection and Elimination

• Develop a storm sewer system map that identifies Mn/DOT Metro District’s pipes (at least 24 inches or larger), manholes, catch basins, aprons, ditches, outfalls, ponds, sediment basins and structural pollution control devices.
• Develop and implement a plan to detect and address non-stormwater discharges on our right of way.
• Effectively prohibit non-stormwater discharges into our storm sewer system and implement enforcement procedures and actions.
• Educate employees, volunteers and the public of the hazards from illegal discharges and the improper disposal of wastes.

4. Construction Site Discharge Controls

• Mn/DOT Metro District follows all NPDES requirements for construction including:
• Implementing proper erosion & sediment controls and controls for other wastes on construction sites of one acre or greater in size
• Implementing procedures for site plan review
• Implementings site inspection and enforcement of control measures with sanctions to ensure compliance
• Implementing procedures for receipt and consideration of information submitted by the public

5. Post-Construction Controls for New Development

• Permit language which addresses volume, rate and quality of stormwater discharging onto Mn/DOT Metro right of way will be incorporated into existing permit requirements.

6. Good Housekeeping & Pollution Prevention

• Training is provided for:
  
  • Erosion and sediment control practices during maintenance activities.
  • Proper maintenance practices at facilities (truck stations and buildings) including stockpile areas, storage and hazardous waste areas, material handling areas and fleet operation areas.
  • Proper inspection of stormwater systems.
  • Illicit discharge detection and elimination.
• Street sweeping practices in the spring of each year will continue
• Anti-icing and de-icing methods will continue to be analyzed and low environmental impact measures will be incorporated where available.
• The vegetation management program will continue.
• Structural pollution control devices, ponds, sediment basins, outfalls, pipes, manholes, catch basins and aprons will continue to be inventoried and inspected.
• Cleaning and repair projects involving pipes, ponds, and structural pollution control devices will continue to occur.
• All inspection, cleaning and repair activities will be recorded and optimum frequencies will be determined.
