Provides overview of permitting process for a Class 1 modification to an existing industrial or hazardous waste permit.

Circumstances requiring a Class 1 modification of a solid waste permit are found in 30 Texas Administrative Code (TAC) §305.69(k)Exit the TCEQ. Items marked with a superscript 1 (i.e., Class 11) are called Class 1ED modifications and have a different administrative process to follow. Processing a Class 1 modification may take 90 days. The application forms referenced on this page may be found in Industrial and Hazardous Waste Forms and Other Permitting Information.

Here is what you need to provide, as set out in 30 TAC §305.69 (b)Exit the TCEQ for a Class 1 modification:

  2. An original Part B application plus 3 full copies, consisting of, at a minimum:
    • Section I of the Part B application;
    • replacement pages for the portions of the application that changed as a result of the modification; and
    • if your core data has changed, a completed Core Data Form. (Instructions for completing the Core Data Form).
  3. A description of the exact changes to be made to the permit conditions and supporting documents referenced by the permit;
  4. An explanation of why the Class 1 modification is needed; and
  5. Within 7 calendar days after the change is put into effect, submit the Part B application with a photostatic copy of the check and the Part A appplication, if required, by certified mail or other means that establish proof of delivery to:
