La. Stat. tit. 30 § 571
The governor of Louisiana shall have the authority pursuant to the police powers granted him by the constitution of this state, from time to time to declare a state of emergency as a result of extreme shortages of existing intrastate natural gas for human needs pursuant to Paragraphs (a) through (e) of Subsection (1) of R.S. 30:572. In connection therewith, as soon as practicable, the commissioner shall establish and promulgate a plan for statewide emergency intrastate natural gas conservation, allocation or rationing, which shall be implemented and enforced by the commissioner under controls and enforcement procedures hereinafter provided. The plan shall remain in effect as implemented and changed from time to time by the commissioner, until the governor, by proclamation, shall declare that a state energy emergency no longer exists. The plan shall maintain, preserve and protect all vital services in the state depending upon intrastate natural gas and, to the extent deemed practicable by the commissioner, shall provide for the curtailment of unnecessary and lesser priority uses of intrastate natural gas.
