Applying for a Substantial Change to the Terms of the Nutrient Management Plan of a Concentrated Animal Feeding Operation

How to apply for a substantial change to the terms of the nutrient management plan of a large concentrated animal feeding operation under Texas water quality General Permit TXG920000.

What Constitutes a Substantial Change?

NOTE: These changes are not applicable to State-only CAFOs.

  • Changing animal type or increasing authorized head count that increases the manure production at the CAFO by 50% or less of the maximum operating capacity stated in the initial authorization for the facility under TXG920000;
  • Adding land management units or increasing application acreage; and
  • Using a crop or yield goal to determine maximum application rates for manure or wastewater not included in the CAFO’s authorization.

How to Apply

To obtain coverage under this general permit, follow these steps:

  1. Read general permit TXG920000 Adobe Acrobat PDF Document to make sure it applies to your situation.
  2. Prepare a Pollution Prevention Plan. For more details, see Part III of the general permit (TXG920000).
  3. Submit a notice of change application package which includes:
  • Notice of Change (NOC) Form TCEQ 20511Microsoft Word Document
  • The updated Nutrient Management Plan (NMP), based on the CAFO’s current soil, effluent and manure analyses

The Public Comment Period

  2. We will provide copies of all your application package materials to be available in the TCEQ’s Office of the Chief Clerk in Austin and the TCEQ Regional Office where the CAFO is located. We will also include a technical summary and the Executive Director's Preliminary Decision, and the General Permit TXG920000 Adobe Acrobat PDF Document

The Executive Director’s Review

  • The Executive Director, after considering public comment, will incorporate the revised terms of the NMP into the permit and the permit record and notify the permittee and the public of the revised terms and conditions.
  • If the revised NMP and technical information meet the requirements of the general permit and the Executive Director approves the request for changes, we will send you a confirmation. If your coverage is denied, we will notify you.
