Featured article: 2020 permit issuance update


The 2020 permit developments are in full swing. Changes are being refined, new language is being drafted, and staff recently updated the reissuance timeline:

  • November 2018 - mid-January 2019: Draft changes
  • Mid-January – mid-February 2019: submit draft to EPA and MPCA legal staff for review.
  • March 2019: Public notice draft permit
  • April- May 2019: Review, respond to comments
  • May 31, 2019: Finalize permit language
  • June 30, 2019:  MPCA commissioner approval
  • July 5 - October 5, 2019: Apply for coverage; all applicants must apply 180 days before the current permit expires
  • April 5, 2020: “New” permit is reissued and effective

Change in format

One of the biggest changes has nothing to do with any changes to permit requirements. MPCA has a new agency-wide database called Tempo, and this general permit must be completely re-formatted to “fit” that new database. The entire permit will have language inserted into table format, one row per requirement. To see an example of a before-and-after stormwater permit, compare our Construction Stormwater 2013 general permit to the newly issued 2018 general permit.

Changes to permit requirements

Staff continues to spend time on additional training requirements, vehicle tracking issues, and adding construction stormwater requirements to certain sectors (thus eliminating the need of a separate construction stormwater permit). Anti-degradation requirements are being thoroughly researched for possible changes. Also, additional salt management requirements are being considered for all permittees with salt storage onsite, outside.
