Mineral mining and processing (SIC 14) and associated activities, such as mobile hot plants, concrete batch plants and stockpiles are covered by the mineral mining storm water permit. Non-mineral mining activities and fuels, such as coal, should use the general industrial storm water permit.
Please note that the general mineral mining 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 Mineral Mining Activities (MMGP) renewal, effective January 1, 2025 and expiring December 31, 2029. To maintain existing coverage for your facility (or facilities) under the new MMGP you must re-apply (renew). Known contacts for current (extended) permit authorizations will receive emails from WDEQ. These emails will contain renewal instructions. 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.
The renewal and fee payment deadline is March 3, 2025. Failure to submit a renewal by April 11, 2025 shall result in permit coverage termination. If you believe MMGP permit coverage for a particular facility is no longer required, please let us know the circumstances via email to both of the addresses below. A completed Notice of Termination form may be required.
If you haven’t received a WDEQ notification regarding MMGP renewal by January 10, 2025, please check your email spam before contacting both of us at .: Anita Rehner (anita.rehner@wyo.gov, 307-777-5622); Katy Sprouse (katy.sprouse@wyo.gov, 307-777-7570).
Make sure to include your WYPDES permit authorization number(s) (starting with ‘WYR32’, followed by 4 unique digits) and facility name(s) in your email so that we can better assist you.
Applicants for new MMGP coverage must either apply through the new WYIMS public-facing permitting system or use the Notice of Intent 2025 posted on this page and follow the instructions within it. Permittees will be emailed WYIMS usage instructions with the renewal notification.
Water Quality Division requires permit fees for new individual permits and MMGP (general permit authorizations) to be submitted with the permit application or Notice of Intent (NOI) form. All storm water general permit authorizations have variable fees that must be calculated depending upon the coverage start date and length of permit term. Fees are $200 per 12-month period, with no pro-ration for partial years. The “Fee Calculator” may be used to determine the proper amount to be submitted with each general permit NOI or renewal. The method of payment varies depending on how the NOI or renewal request is submitted. Applicants that submit an application or NOI electronically via the WDEQ Water Quality Division Downloads link, shall be pay fees electronically via https://deq.wyoming.gov/e-payment/. Applicants that use the WYIMS permitting system (https://wyims.wyo.gov/ncore/external/home) may pay through WYIMS (preferred) or download a payment voucher generated by WYIMS and submit it by mail to the Cheyenne office address shown on the voucher with a check for the fee.
Checks must be made out to “WDEQ, Water Quality Division” and include in the memo the authorization number (if existing) or type of permit being applied for and the permitted company name. See the NOI or your renewal instructions (for authorizations being renewed in early 2025) for payment options.
