30 Tex. Admin. Code § 321.47
In lieu of the procedure specified in §321.33 of this title (relating to Applicability), the owner or operator of any existing facility as described in §321.33(a) of this title (relating to Applicability) may submit to the executive director written notice that they will operate the facility in accordance with the provisions of this subchapter. Such notice shall be on forms approved by the executive director and submitted within 60 days of the effective date of these amended (1999) rules. Subject to the provisions of §321.35(h) of this title (relating to Procedures for Making Application for Registration), a facility for which a complete and accurate written notice has been submitted in accordance with this section may operate as an authorized TPDES facility under this amended subchapter for the remainder of the unexpired term of their current authorization. Such initial TPDES authorization shall not require compliance with "air quality only" provisions of this title that can be accomplished only by making structural changes to a structure that is currently in compliance with the design and engineering standards in the facility's latest permit. Upon expiration of the specified term of the facility's current state-only authorization, the owner or operator shall file for renewal in accordance with either §321.34 or §321.35 of this title (relating to Procedures for Making Application for an Individual Permit or Procedures for Making Application for Registration). If the existing authorization contains any special conditions or provisions, the owner or operator shall operate such facility in accordance with the provisions of this subchapter and any additional special provisions or conditions specified in the authorization.
