(a) This section shall be known and may be cited as the Mills-Hayes Act. (b) No tax shall be imposed upon fuel used by: (1) Any transit district, transit authority, city, or county owning and operating a local transit system itself or through a wholly owned nonprofit corporation. (2) Any private entity providing transportation services for the transportation of people under contract or agreement, except general franchise agreements, with a public agency authorized to provide public transportation services, only for fuels consumed while providing services under such contracts or agreements entered into subsequent to the effective date of this act. (3) Any passenger stage corporation subject to the jurisdiction of the Public Utilities Commission when the motor vehicles of such passenger stage corporation are exclusively operated in urban or suburban areas or between cities in close proximity for the transportation of persons for hire, compensation, or profit, provided, however, that the exemption is not extended to any line or lines operated by such passenger stage corporation which shall exceed 50 miles of one-way route mileage. (4) Any common carrier of passengers operating exclusively on any line or lines within the limits of a single city between fixed termini or over a regular route, 98 percent of whose operations, as measured by total route mileage operated, are exclusively within the limits of a single city, and who by reason thereof is not a passenger stage corporation subject to the jurisdiction of the Public Utilities Commission.

(6) Any private entity providing transportation services for the purposes specified in paragraph (5) under contract or agreement with a school district, community college district, or county superintendent of schools, only for fuels consumed while providing services under those contracts or agreements entered into subsequent to the effective date of the act adding this paragraph.

(d) The exemption provided for in subdivision (b) and the payments provided for in subdivision (c) shall not be applicable to fuel used by a charter-party carrier of passengers.

(e) There are in the State of California many local bus transit operators in need of financial assistance from sources other than the local property tax. These operators are performing essential public transit service as a vital counterpart of the streets and highways. It is the purpose of this section to provide relief from the payment of use fuel tax for local transit operators and it is the intent of the Legislature that the funds accruing to such operators shall be used for the improvement of their transit operations and to aid in providing better transit service to and from places of employment. There are also in the State of California many private entities providing public transportation services for the transportation of people in vehicles other than buses under contract or agreement with local government, transit districts or local bus transit operators. It is the purpose of this section to provide relief from the payment of use fuel taxes for diesel fuel for those private entities only for fuel consumed while providing these services.
