Modifications to Existing Facilities under Senate Bill 1126

This page describes what is needed to qualify for an existing facility to make modifications under the expedited process established in Senate Bill 1126.

To qualify as "Modifications to Existing Facilities under Senate Bill 1126," changes must meet each of these criteria:

  • Either meet 10-year-old BACT (best available control technologies) or pertain to a facility that has been permitted in the last 120 months
  • Result in no net increase in emissions for each pollutant category

When modifications to an existing facility meet these criteria, Senate Bill 1126 of the 78th Texas Legislature allows the existing permit to be modified through an expedited process. This process is less cumbersome than other methods for changing the conditions of the permit.

Additional Requirements

On September 15, 2010 the commission adopted amendments to the rules related to the qualified facility program to address EPA indentified deficiencies in the program which led to its disapproval as a SIP amendment. The major features of the amended rules, which become effective on October 7, 2010, include:

  • Applicants must make a determination of the applicability of major NSR. For those of you who have reviewed applications, this is not a new requirement; we have just made it very explicit.
  • Qualified facility changes to case-by-case permits require an application for a permit revision in addition to the PI-E form. Revision has a specific meaning for qualified facilities.
  • Qualified facility changes in facilities authorized by standard permit require an update to registration representations and the PI-E.
  • Changes involving PBRs require the PI-E only.
  • All qualified facility changes require prior notification.
  • VOCs de-listed by EPA may be interchanged with those currently on the list. No interchange of current VOC for de-listed compounds.

To Modify Your Permit under SB 1126:

  • Complete TCEQ Form 10230, PI-E and an application for permit revision (PI-1).
