1. WYPDES permit fees were raised on July 1, 2020.  Fees for storm water permits changed from $100 per each 12-months to $200 per each 12-months.  The maximum fee will be $1000 for a five year term.  All WYPDES permits are affected whether storm water or discharge permits.

2. As of Spring 2023, WDEQ's Wyoming Information Management System (WYIMS) is the preferred method for submitting and managing storm water applications, both new and renewals; transfers; modifications; terminations; and permit contact changes.

   Additional information on how to use WYIMS is available below and under the Storm Water Guidance Documents” tab. Visit https://wyims.wyo.gov/ncore/external/home to create an account and set up new sites or request access to existing sites. Each user must create their own account and, within that account, claim all sites that they would like to access.

   Unable to use WYIMS? Download the applicable fillable PDF application form from the Storm Water Permitting webpage, and submit completed applications with supporting documents and maps via the Electronic Documents Submittal button.
