Concentrated Animal Feeding Operation (CAFO) General Permit: Significant Expansion of an Existing CAFO

If you have an existing CAFO facility currently authorized under the CAFO general permit (TXG920000) and are proposing a significant expansion, you must apply for coverage.

TCEQ reissued the CAFO General Permit (GP) No. TXG920000, with an effective date of July 20, 2024.

The following steps will help you determine if your proposed expansion to your existing CAFO authorization is considered a significant expansion, if it qualifies for coverage under this GP, and how to apply.

Step 1. Determine if Permit Action is a Significant Expansion

A significant expansion is any change to the CAFO that increases the manure production at the CAFO by more than 50%, above the maximum operating capacity stated in the initial authorization for the facility under TXG920000.

If the manure production will be less than 50%, when compared with the initial authorization under the GP, you may consider a substantial change if you are a large CAFO; and a State only CAFO may consider notice of change for state only.

Step 2. Read the General Permit

Read the General Permit TXG920000 and determine if your proposed significant expansion qualifies for coverage.

  • If the GP does not apply to your situation, you might need to obtain an individual permit.
  • If the GP does apply to your situation, continue with Step 3.

Step 3. Review Compliance History

Review your facility's compliance history ranking:

  • If your facility has a ranking of “high performer,” “satisfactory performer,” or "inadequate information," continue to Step 4.
  • If the compliance history ranking is "unsatisfactory performer," then your facility is not eligible for coverage under a general permit. You must apply for an individual permit instead.

Step 5. Application Review

If you qualify for coverage under this general permit but would rather have an individual permit, you may request coverage under that permit instead.

We will review the NOI significant expansion and will take one of the following actions:

  • If we find that your application is complete, we will draft and send you a public notice to have published in the local newspaper.
  • If any information is incomplete or missing, we will send you a letter requesting the necessary information. You will have 30 days (about a month) to respond to this request.
  • If coverage has been denied, we will send you a denial letter.

Step 6. Public Comment Period

If we find that your NOI is complete, we will send you a public notice to have published in the local newspaper.

  1. A 30-day public comment period begins on the date the notice is published.
  2. By the date this notice is published, you must put a copy of the application, the technical summary, General Permit TXG920000 , and the Executive Director's Preliminary Decision in a public building for viewing—for example, in the county courthouse, county extension agent's office, or a public library.
  3. During the public comment period, interested persons may submit comments to the Office of the Chief Clerk (OCC). If a public meeting is required, then you must publish a notice for the meeting at least 30 days before it is held.
  4. Upon newspaper publication, you must email proof of publication to the OCC at PROOFS@tceq.texas.gov or by mail to the address provided in the affidavit instructions.

Step 7. Executive Director’s Review

The Executive Director, after considering the public comments received, will determine whether the NOI and technical application meet the requirements of this general permit, and take one of the following actions:

  • If your coverage under this general permit is approved, we will send you a certificate shoring the increased headcount information and a confirmation letter.
  • If your coverage is denied, we will send you a denial letter.

You must keep a copy of the NOI and the acknowledgement certificate onsite.

Remember: Permit coverage will remain active until you request termination. You must submit a Notice of Termination Form (TCEQ-20343) to TCEQ to cancel your permit. If your coverage is active September 1 of any given year, you will owe a water quality fee for that year.
