In accordance with criteria established by the department, each agency shall develop and implement a uniform cost accounting and reporting system to ascertain the cost per mile of each motor vehicle used by the State under their control. Agencies presently operating under existing systems may continue to do so provided that departmental approval is required and that the existing systems are uniform with the criteria established by the department. All expenditures on a vehicle for gasoline and oil shall be purchased in one of the following ways:

(1) from state-owned facilities and paid for by the use of Universal State Credit Cards except where agencies purchase these products in bulk;

(2) from any fuel outlet where gasoline and oil are sold regardless of whether the outlet accepts a credit or charge card when the purchase is necessary or in the best interest of the State; and

(3) from a fuel outlet where gasoline and oil are sold when that outlet agrees to accept the Universal State Credit Card.

These provisions regarding purchase of gasoline and oil and usability of the state credit card also apply to alternative transportation fuels where available. The department shall adjust the budgetary appropriation for "Operating Expenses-Lease Fleet" to reflect the dollar savings realized by these provisions and transfer such amount to other areas of the State Fleet Management Program. The department shall promulgate regulations regarding the purchase of motor vehicle equipment and supplies to ensure that agencies within a reasonable distance are not duplicating maintenance services or purchasing equipment that is not in the best interest of the State. The department shall develop a uniform method to be used by the agencies to determine the cost per mile for each vehicle operated by the State.
