Tex. Water Code § 5.514: ORDER ISSUED UNDER AIR EMERGENCY.

(a) If the commission finds that a generalized condition of air pollution exists that creates an emergency requiring immediate action to protect human health or safety, the commission, with the concurrence of the governor, may issue an emergency order requiring a person causing or contributing to the air pollution to immediately reduce or discontinue the emission of air contaminants.

(b) If the commission finds that emissions from one or more sources are causing imminent danger to human health or safety but that there is not a generalized condition of air pollution under Subsection (a), the commission may issue an emergency order requiring the persons responsible for the emissions to immediately reduce or discontinue the emissions.

(c) Notwithstanding Section 5.504, the commission shall affirm, modify, or set aside an order issued under this section not later than 24 hours after the hearing under that section begins and without adjournment of the hearing.

(d) This section does not limit any power that the governor or another officer may have to declare an emergency and to act on that declaration if the power is conferred by law or inheres in the office.
