This page contains documents related to the Industrial General Permit (IGP).
Certain industrial facilities are required to seek coverage under the general industrial storm water permit. Facilities most commonly covered in Wyoming are most mines (mineral mines are covered under the mineral mining permit, see above), facilities that produce cement products, many wood product facilities, airports, junk yards, and scrap recycling facilities. Coverage is based on the facility’s Standard Industrial Classification (SIC) code.
Please note that the general industrial storm water permit is not available to facilities where storm water runoff has the potential to discharge to class 1 waters. Facilities may apply for coverage under an individual storm water permit.
UPDATE 02/06/2023
***All existing authorizations for industrial storm water coverage have been administratively continued, and did NOT expire on 8/31/2022. A new Wyoming Industrial General Permit (IGP) has been drafted and will appear in the WYPDES February 17th, 2023 Public Notice. After the 30-day public comment phase, the permit will be revised if necessary to address comments, and then issued. At this time, WDEQ is still accepting new applications for coverage under the Industrial General Permit. Operators of facilities with existing IGP permit coverage do not need to apply for anything until further notice is given. WDEQ will be emailing instructions to permittees when that time comes.
Additionally, a new permitting database that is under development at WDEQ may affect the renewal process, so permittees should wait for further email notification from WDEQ with instructions regarding renewal applications. In the meantime, we will continue to process applications for NEW (not renewal) permit authorizations the usual way. If you are aware of personnel changes at your organization that affect the contact information for your storm water permit authorization(s), please contact Anita Rehner (307-777-5622, anita.rehner@wyo.gov) or Katy Sprouse (307-777-7570, katy.sprouse@wyo.gov) to determine whether the contact information in our database is current. This will ensure that your organization receives email updates. Permittees are welcome to contact us with questions as we proceed.
Payment of Permit Fees
Beginning July 1, 2013 payment of permit fees for individual permits and general permit authorizations are required to be submitted with the permit application or NOI form. All storm water authorizations have variable fees that must be calculated depending upon the NOI date. The "Fee Calculator" should be used to determine the proper amount to be submitted with each NOI. Checks should be made out to the "Dept. of Environmental Quality, Water Quality Division.
