(1) The commission shall find that a gas corporation's expenditures for the construction, operation, and maintenance of natural gas fueling stations and appurtenant natural gas facilities are in the public interest and are just and reasonable, if: (a) the gas corporation's expenditures for the fueling stations and appurtenant facilities: (i) are prudently incurred; and (ii) do not exceed $5,000,000 in any calendar year; (b) the gas corporation shows that the estimated annual incremental increase in revenue related to the stations and facilities exceeds 50% of the annual revenue requirement of the stations and facilities; and (c) the stations and facilities are in service and are being used and are useful.
