(2)(a) The Oregon Department of Administrative Services shall estimate the amount of fuel described in subsection (1) of this section that is used to operate or propel motor boats by conducting a statistically valid, unbiased, independent survey of boat owners. The survey shall be conducted once every four years and shall be designed to estimate the average daily fuel consumption by motor boats and the total days of motor boat use per year. The survey shall be used to determine the amount of the transfer required by subsection (3) of this section for the first transfer that occurs after the survey is completed. If the tax rate changes during the fiscal year, the amount of tax to be transferred shall be prorated based on the percentage of total motor boat use taking place during each tax period.

(b) In years when no survey is conducted, the amount to be transferred under subsection (3) of this section shall be calculated by multiplying the per boat fuel consumption factors from the preceding survey by the number of motor boats as shown by the annual actual count of boat registrations. The resulting amount, in gallons per year, shall be the basis for the determination of the amount to be transferred.

(c) The survey required by paragraph (a) of this subsection shall be developed by a research department within Oregon State University, in consultation with the State Marine Board and the Department of Transportation. The Oregon Department of Administrative Services shall contract for the development and conduct of the survey, and the costs shall be paid by the Department of Transportation. Costs paid by the Department of Transportation may be deducted from the amount transferred to the State Marine Board and to the Oregon Business Development Department under subsection (3) of this section.

(3) The Oregon Department of Administrative Services shall certify the amount of the estimate made under subsection (1) of this section, as reduced by refunds, to the Department of Transportation, to the State Marine Board, to the Oregon Business Development Department and to the State Treasurer. Thereupon, that amount shall be transferred from the Department of Transportation Driver and Motor Vehicle Suspense Account to the:

(a) Boating Safety, Law Enforcement and Facility Account created under ORS 830.140, and is continuously appropriated to the State Marine Board for the purposes for which the moneys in the Boating Safety, Law Enforcement and Facility Account are appropriated; and

(b) Marine Navigation Improvement Fund established under ORS 777.267, and is continuously appropriated to the Oregon Business Development Department for the Oregon Infrastructure Finance Authority for the purposes of paying for portions of the cost of maintenance dredging projects undertaken with equipment owned by the State of Oregon at publicly owned ports and marinas.

(4) Of the amounts transferred under subsection (3) of this section, two cents per gallon of fuel shall first be transferred to the Marine Navigation Improvement Fund and the remaining amounts shall be transferred to the Boating Safety, Law Enforcement and Facility Account.
