New Permit Effective Aug. 1, 2018

The 2018 Construction Stormwater Permit is effective for newly permitted projects on Wednesday, Aug. 1, 2018. 

Tools & Resources

On July 26, 2018, the Minnesota Pollution Control Agency published the 2018 Construction Stormwater General Permit.  

What's Changed

The most noticeable change in the 2018 Construction Stormwater Permit is that the document has been completely rewritten and reorganized.

Several changes in the 2018 Permit have made compliance easier or reduce cost to homeowners:

  • Making cost-saving amendments to the SWPPP
  • The mandatory seven-day waiting period  for new permits is now once the payment has been processed (typically one day).

A change in the Federal NPDES Permit has been included in the draft 2018 Permit. Materials on sites must be covered to prevent contact with stormwater. This is estimated to add $300 to the cost of each home. 

What's The Same


The new format and clear language have caused the 2018 Construction Stormwater Permit to look very different from the current version. Although the permit has been rewritten, the 2018 Permit contains fewer changes than the current Permit did when it was adopted in 2013. 

The cost of complying with the permit is expected to rise $300 per home, compared to a $3,500 per home increase in 2013. 

Projects operating under the current (2013) Permit will have 18 months be completed and the Permit closed. After 18 months, a 2018 Permit must be obtained (at no additional cost) if existing projects are not completed.
