Qualified Changes to Existing Facilities under Senate Bill 1126

This page describes criteria for an existing facility to authorize qualified changes under Senate Bill 1126, codified in 30 TAC Section 116.116(e).

Senate Bill 1126 of the 74th Texas Legislature allows the authorization of physical or operational changes at an existing site without obtaining a permit amendment. The modifications must meet specific criteria and the permit holder must notify the TCEQ. This process is less cumbersome than other methods for authorizing changes to existing facilities.

EPA approved the amended TCEQ rules and SIP via publication in the Federal Register on September 9, 2016 and the SIP changes became effective October 1, 2016.
