Mich. Comp. Laws § 290.649k
If the governor declares an emergency under the emergency management act, 1976 PA 390, MCL 30.401 to 30.421, or 1982 PA 191, MCL 10.81 to 10.89, the governor may exercise his or her discretion to grant a temporary variance suspending the low vapor pressure fuel provisions of this act or rules promulgated under this act if the governor concludes it is necessary to avoid disruptions in fuel supply. Fuel manufactured, sold, distributed, offered for sale or distribution, dispensed, offered for supply, stored, or transported under the variance shall be deemed compliant with the low vapor pressure fuel requirements of this act. The fine described in section 9l does not apply to a variance described in this section. The variance shall be granted only for the minimum period necessary. The allowable vapor pressure under the variance shall be the minimum the governor considers necessary and in no event shall the variance allow the refiner, distributor, or terminal to operate with a vapor pressure of greater than 9.0 psi.
