(e) Sixty percent of the proceeds of the revenue from the motor fuel taxes on aviation fuel, excluding the amount determined to have been spent by the state in its collection, shall be refunded to a municipality owning and operating or leasing and operating an airport in the proportion that the revenue was collected at the municipal airport. All other proceeds of the motor fuel taxes on aviation fuel shall be paid into a special aviation fuel tax account in the state general fund. The legislature may appropriate funds from this account for capital or operating costs of airports.

(f) The proceeds from the revenue from the tax on motor fuel used in boats and watercraft of all descriptions shall be deposited in a special watercraft fuel tax account in the general fund. The legislature may appropriate from this account for water and harbor facilities.

(g) The proceeds of the revenue from the tax on all motor fuels, except as provided in (e), (f) and (j) of this section, shall be deposited in a special highway fuel tax account in the state general fund. The legislature may appropriate funds from it for expenditure by the Department of Transportation and Public Facilities directly or as matched with available federal-aid highway money for maintenance of highways, construction of highway projects and ferries included in the program provided for in AS 19.10.150, including approaches, appurtenances and related facilities and acquisition of rights-of-way or easements, and other highway costs including surveys, administration, and related matters. All departments of the state government authorized to spend funds collected from taxes imposed by this chapter shall perform, when feasible, all construction or reconstruction projects by contract after the projects have been advertised for competitive bids, except that, when feasible, arrangements shall be made with political subdivisions to carry out the construction or reconstruction projects. If it is not feasible for the work to be performed by state engineering forces, the commissioner of transportation and public facilities may contract on a professional basis with private engineering firms for road design, bridge design, and services in connection with surveys. If more than one private engineering firm is available for the work the contracts shall be entered into on a negotiated basis.

(h) All motor fuel tax receipts shall be paid into the general fund and distributed to the proper accounts in the general fund. Valid motor fuel tax refund claims shall be paid from the highway fuel tax account in the general fund.
