Proposed Rules and Regulations

The Water Quality Division will present proposed revisions to Water Quality Rules Chapter 1, Wyoming Surface Water Quality Standards; and Chapter 2, Permit Regulations for Discharges to Wyoming Surface Waters to the Water and Waste Advisory Board at their June 13, 2024 meeting, starting at 9:00 a.m. The proposed revisions to Chapter 1 (1) fulfill the federal requirements at 40 CFR § 131.20, (2) restructure and align requirements with state law and federal law, regulations, and guidance; (3) revise designated uses and remove the designated use classification system; and (4) provide minor updates to specific water quality criteria. The proposed revisions to Chapter 2 (1) update references to the designated use classification system to reflect proposed revisions to Chapter 1; and (2) incorporate provisions related to fish toxicants, aquatic pesticides, and short-term sediment disturbance that Water Quality Division proposes to move from Chapter 1 to Chapter 2. More information is available at: http://deq.wyoming.gov/shwd/wwab/ under the “Upcoming Meeting” tab

General Industrial Storm Water

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 12/18/2023—IGP Renewal

WDEQ issued a General Permit for Storm Water Discharges Associated with Industrial Activities (IGP) renewal, effective June 1, 2023 and expiring May 31, 2028.  The deadline for submission of renewal application forms and fee payments was July 31, 2023.  To maintain existing coverage for your facility (or facilities) under the new IGP you must re-apply.  If you have not yet submitted your renewal form/fee, please do so as soon as possible.   Failure to submit a renewal application shall result in permit coverage termination.  If you no longer require IGP permit coverage for a particular facility, please submit a Notice of Termination via our Electronic Documents Submittal portal above.  If you have questions, contact us via email to both of the following addresses: anita.rehner@wyo.gov and katy.sprouse@wyo.gov.  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.

We are currently processing the renewal applications received since June 2023.  We anticipate that this process will continue at least through January 2024.  If you have concerns about the renewal for your facility, please contact us via the email addresses listed above.

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.
