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.
WDEQ has issued a General Permit for Storm Water Discharges Associated with Industrial Activities (IGP) renewal, effective June 1, 2023 and expiring May 31, 2028. To maintain existing coverage for your facility (or facilities) under the new IGP you must re-apply. Contacts for current permit authorizations will receive emails from DEQ’s Smartsheet system over the next few weeks indicating that they “have X updates to complete”. These emails will contain instructions on how to re-apply and a link to Smartsheet via an “Open Request” button. Your facility renewal form(s) which are downloadable, pre-filled PDF(s) will appear as attachments on the landing page once the button is clicked. Note that these notifications may go out to multiple people to increase the likelihood that DEQ reaches someone at your company. ONLY ONE RENEWAL SUBMISSION/FEE PER PERMIT AUTHORIZATION NUMBER IS NECESSARY, so please coordinate to avoid duplicate submissions.
Renewal application form and fee payment deadline is July 31, 2023. Failure to submit your application forms by July 31, 2023 shall result in permit coverage termination. If you no longer require IGP permit coverage for a particular facility, please let us know via email to both of the addresses below.
In addition, please check your spam for emails from the Smartsheet system over the next few weeks. If you aren’t notified by us regarding your renewal forms by July 1, 2023, please contact us at both of the following emails: firstname.lastname@example.org, or email@example.com. Make sure to include your WYPDES permit authorization number(s) (starting with ‘WYR00’, followed by 4 unique digits) and facility name(s) in your email so that we can better assist you.
Applicants for new IGP coverage must use the Notice of Intent_2023 posted on this page and follow the instructions within it.
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.
