16 Tex. Admin. Code § 22.283
Notwithstanding any other provision of these rules, if the commission finds that an imminent peril to the public health, safety, or welfare or a requirement of state or federal law requires adoption of a rule on fewer than 30-days notice and states in writing its reasons for that finding, it may proceed without prior notice or hearing or on any abbreviated notice and hearing that it finds practicable to adopt an emergency rule. The commission shall set forth the requisite finding in the preamble to the rule. An emergency rule adopted under the provisions of this section, and the commission's written reasons for the adoption, shall be filed in the office of the secretary of state for publication in the Texas Register. All of the requirements of APA, §2001.024, apply to this section.
