30 Tex. Admin. Code § 116.310
The executive director shall provide written notice to the permit holder that the permit is scheduled for review. Such notice must be provided by certified or registered United States mail, or an electronic method which can provide verification of receipt of the notice, no less than 12 months prior to the expiration of the permit. The notice must specify the procedure for filing an application for review and the information to be included in the application. Under Texas Occupations Code, § 55.002, the commission shall exempt a permit holder from any increased fee or other penalty for failure to renew the permit if the individual establishes, to the satisfaction of the commission, that the failure to renew in a timely manner occurred because the individual was on active duty in the United States Armed Forces serving outside the State of Texas.
