Recent appeal history

In 2022, Ecology issued updated CAFO general permits. A coalition of organizations appealed those permits. Their appeal raised concerns about monitoring requirements, clarity of the permit language, Manure Pollution Prevention Plans, and whether the permits included strong enough conditions to protect waters of the state.

In March 2025, the Pollution Control Hearings Board ruled in favor of the organizations on some issues. The Board ordered Ecology to make specific changes to the permits and sent them back to the agency for revision, though they did not impose a deadline. The Board did not rule on several other issues raised in the appeal.

After the ruling, Ecology confirmed it would revise and reissue the permits according to the formal public process. The organizations then withdrew their appeal on the remaining issues. As a result, the 2022 CAFO permits remain in effect until Ecology completes a formal public process to reissue them.

Ecology plans to reissue the permits before their current expiration date of Jan. 5, 2028.

You can read the full Summary Judgment Order or find additional details on the Pollution Control Hearings Board webpage for Case P23-002.

Do I need a CAFO permit?

We use a permitting threshold (see below) that lists the number of animals at a facility, along with information on how the operation handles their waste, to determine if a facility needs a permit. A farm with fewer animals, only qualifies for this permit if Ecology designates the farm as a “significant contributor of pollutants.”

If manure management problems are detected at a smaller farm, we will work with owners to give guidance on the best management practices to protect water quality. We often partner with local groups, such as conservation districts, to identify resources and financial assistance opportunities they can apply for to help prevent manure from becoming a pollutant. 

Permit threshold

For each type of animal, the number of animals listed are needed at any one facility to be considered a medium or large CAFO.

Step 1: Access the Water Quality Web Permitting Portal Access through Secure Access Washington (SAW)

To apply for new coverage or reapply for continued coverage, you must use Secure Access Washington (SAW). SAW is the secure gateway to many government services including what you need, the Water Quality Permitting Portal (WQ Web Portal). Download a PDF of detailed instructions, with screen capture images, with information on how to set up WQ Web Portal or follow the instructions here:

1. Login to SecureAccess Washington or sign up.
2. Under My Services, from the top level SAW navigation, either
   • Select Continue to Water Quality Permitting Portal
     or

Step 2: Complete your Application for Permit Coverage

For a new facility not currently covered by this general permit, you need to submit a new application which is called a Notice of Intent (NOI). Download a PDF of detailed application instructions with screen capture images or follow the instructions below:

1. Login to Secure Access Washington.
2. Under My Services go to the WQWebPortal.
3. Select NOI: General Permit Coverage – Renewal – Notice of Intent (NOI) on the WQ Web Portal home page.
4. On the Notice of Intent (NOI) webpage select + New corresponding to the name of the general permit you are applying for. If you are completing an existing electronic application, click Search my existing Notice of Intent (NOI) applications and enter your permit number, including any leading letters, in the search box. Select Load.
5. Fill out your entire application by completing all of the tabs.
6. When you are finished select Save and Continue.
7. Attach any necessary information. Select Save and Continue.
8. Sign the form by either of the following methods:
   • Use your electronic signature if you have an NOI signature on file.
     or

Questions

Public review of permit applications & Manure Pollution Prevention Plans

Animal operations that are seeking new coverage under the CAFO general permit must submit their permit application and Manure Pollution Prevention Plan to Ecology for review. Existing permitted CAFOs with proposed changes to their Manure Pollution Prevention Plan also need to submit these changes to Ecology for review. In both situations, these materials are also available for public review and comment for 30 days. 

For new applications, we are specifically interested in comments about whether it is appropriate for the facility to be covered under the permit. At the end of the public comment period, we will consider comments and may request changes to the Manure Pollution Prevention Plan or permit application before issuing a decision.
