Electronic Documents Submittal

In response to the Governor's request to limit contact and the move toward staff working remotely for the near future, the WDEQ Water Quality Division (WQD) has made electronic document submittal available. This includes permit applications, response to comments, reports, and other communications. Forms have been set up for individual WQD Sections (Watershed, WYPDES, Groundwater, Water/Wastewater), and a form is also available for general WQD submittals. Please choose the appropriate form from the list of links below to upload your documents. If submitted electronically, no hardcopy is required to be submitted unless you are contacted by a WQD Section Manager with a request to submit the hard copy. Please note that the Water Quality Division is unable to accept comments on documents in public notice via these forms. Please refer to the public notice for instructions on how to submit comments.

The DEQ undertakes enforcement actions to preserve safe environmental conditions throughout Wyoming. 

This page contains information on the enforcement actions that the Water Quality Division may undertake, as well as a record of enforcement actions that have been undertaken by WQD.

Authorized Permit Archive

Was your project permitted? Looking for the permit? This page contains steps to help you find the Notification of Coverage (NOC) or Permit to Construct issued by the Water & Wastewater Permitting Programs.

Note: Only small wastewater systems permitted in Carbon, Crook, Niobrara, Platte, or Weston Counties (and commercial small wastewater systems in Campbell County) have been permitted by the Water & Wastewater Program. Please contact the permitting authority to locate permits for small wastewater systems in any other county.

Follow these steps to find your permit:

1. Find your permit in the Authorized Permits Excel file. It may take 15 months for your permit to appear in this document and archive. If your NOC was issued within the last 30 days, it will be posted on the Recent General Permit Authorizations page.

2. Make note of the permit or NOC number, which is listed in the “APPNO” column. The first two (2) numbers of the permit number are the year in which the permit was issued, and the last three (3) are the application number.

3. If you cannot locate your permit or NOC, please contact the appropriate District Engineer.

4. Open the file containing your permit or NOC number and scroll through the document until you reach your number.

Recent General Permit Authorizations

The DEQ Water Quality Division accepts comments on all permits authorized under a general permit for a period of 30 days, as provided for in W.S. 35-11-801(d).

Interested persons may mail or fax comments to the main Cheyenne office. The ‘Date’ column in the table below indicates the date the authorization was posted to the website. Comments must be received before 5:00 pm on the 30th day after the authorization was posted to the website. For example, comments for an authorization posted on 10/1/18 must be received by 5:00 p.m. on 10/31/18. DEQ does not accept emailed comments.

You may sort the table by posting date or search for the type of general permit, the county where the permit was issued, the permit number, or the name of the person or company to whom the permit was issued.

If you wish to review the general permit documents, please go to the web page for each permitting program:

Subdivision reviews are governed by Water Quality Rules and Regulations, Chapter 23 and Wyoming Statutes 18-5-301 to 315.

DEQ reviews all subdivisions that meet the following criteria:

  • Subdivisions with more than 5 parcels
  • Subdivisions where parcels are larger than 35 acres
  • Subdivisions with unique site conditions or other criteria where the counties choose not to review them

flowchart of the subdivision review process explains the steps involved in a DEQ review.

Required analyses for nitrate loading, minimum isolation distances and impacts on public drinking water supply wells are described in Chapter 23, Appendices A, B, and C.

Subdivisions reviewed by counties are exempted from DEQ review.  The table below lists how many subdivision parcels each county will review and what additional criteria may apply. Please verify these criteria with the county before proceeding.
