Online Stormwater General Permit Application and Renewal Instructions


Renewing an Existing Authorization:

To renew an existing authorization, you must know your authorization number. The authorization number is printed on all correspondence sent by the Iowa DNR about your stormwater Notice of Intent (NOI) and authorization.

Begin the online renewal process.

After indicating that you wish to renew your current authorization, enter your authorization number and click on "Ok". The first page of the online renewal process will appear. The blue "NEXT" link at the bottom of the page will take you to the first page of authorization information. Verify the information, changing any that is incorrect, and proceed through the pages by clicking the blue "NEXT" link at the bottom of each page. You may access previous pages by clicking on the blue "PREVIOUS" link on the bottom of each page.

Read and follow the instructions on every page. Failure to do this will likely result in significantly diminished satisfaction with the renewal process. If you still need assistance after reading and following the instructions, please contact Mark Lasnek at 515-204-9234 or Mark.Lasnek@dnr.iowa.gov.

Requirement for an Individual Stormwater NPDES Permit


Please note, any discharge from a facility or construction site that may temporarily degrade an Outstanding National Resource Water or Outstanding State Resource Water is required to be permitted by an individual NPDES permit, as stipulated in 567 Chapter 64 of the Iowa Administrative Code and in the Iowa Antidegradation Implementation Procedure. General permit coverage is not available for these discharges. The list of these waters is located in Appendix B of the Antidegradation Implementation Procedure.
