Cal. Wat. Code § 31013
Notwithstanding any other provision of law, the Mammoth County Water District may operate a propane gas distribution service for residents of the district and may do any act necessary to furnish sufficient propane gas to residents of the district.
The provisions of this section are necessary because of the great need for propane gas service within the area of the Mammoth County Water District. There is no other local governmental entity willing to provide such service to the people of the district. This problem is not common to all districts formed under this division. It is therefore hereby declared that a general law cannot be made applicable and that the enactment of this section as a special law is necessary for the solution of problems existing in the Mammoth County Water District.
