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 Water & Wastewater Program works to ensure safe and adequate supplies of drinking water and the proper disposal of wastewater.

The Concentrated Animal Feeding Operation (CAFO) permitting program provides oversight for facilities housing large concentrations of livestock to ensure that the waters of the state are not negatively impacted and that the waste these animals generate are appropriately treated.

We work with CAFOs under three separate regulatory programs, the WY Point Source Discharge Elimination System Program (WYPDES), the Water and Wastewater Construction Permitting Program, and for some larger CAFOs, the Air Quality Permitting Program.

The process of attaining a CAFO Permit entails the following steps: 

  1. Contact us.
    The permitting process involves multiple regulatory programs. You will need a permit from each regulatory program, including a WYPDES Discharge Permit, a Water and Wastewater Permit to Construct, and potentially an Air Quality Permit.

    You will likely need to meet with members of our team to review your plans, which usually results in a smoother, less expensive design and permitting process. See the bottom of this page for more contact information.

  2. Hire an engineer.
    An engineer will help develop your wastewater, waste, and nutrient management plans and design the structures required by your permit. Financial assistance for this step may be available through the USDA Rural Development Program.

  3. Complete paperwork. 
    You will need to complete several forms and applications to apply for permits from the three regulatory programs with oversight for CAFO. 

    Some of these documents require you to submit them along with fees. Additional applications may be required for wastewater runoff and retention systems and/or for swine confinement facilities. 

A permit is required when more than 1,000 head of cattle or an equivalent weight of livestock are confined for more than 45 days, or the facility negatively impacts the waters of the state.

Equivalent livestock weights are listed in Appendix G of state rules Chapter 2.

If you think you need a permit for your Concentrated Animal Feeding Operation, you should gather some information before you contact us. 

  1. Do you have cropland that can be used to dispose of wastewater?
  2. Is your groundwater deeper than 20 feet?
  3. Do the water wells in your area draw from a deep aquifer?
  4. Does your soil have a slow “perc” rate? (caused by soil with clay or silt in it)
  5. Is the groundwater in your area unsuitable for potable use?
  6. Will you be able to grow grass or similar vegetation inside the area of the    containment pond when it is dry?

If your site meets most of the criteria listed above, you may qualify to contain your wastewater runoff in a “Temporary Retention Structure," which is generally cheaper and easier to build than a full retention structure. Even if your site does not meet the Temporary Retention Structure criteria, answers to these questions are needed in order to properly design your wastewater retention facility. 

If you need assistance obtaining this information, your engineer should be able to help you.
