(1) An owner of an operation who elects to make prepayments under this article and the governing body of a local government shall jointly determine and agree upon:

(a) The total amount of prepayments to be made; except that the total amount of prepayments shall not exceed twenty-five percent of the estimate of the operation's projected tax liability to the local government over a twenty-year period, commencing with the taxable year in which the valuation for assessment of the operation is estimated to exceed fifty million dollars;

(b) The amounts and intervals of prepayments and credits for such prepayments; except that an annual prepayment credit shall not be allowed prior to the taxable year in which the operation begins functioning or the valuation for assessment of the operation exceeds fifty million dollars, whichever is earlier, nor shall it exceed twenty-five percent of the taxes due from the operation to that local government for the then current property tax year.

(2) The owner of an operation, the governing body of the local government, the assessor, the treasurer, and the division of property taxation in the department of local affairs shall estimate when the operation's projected valuation for assessment will exceed fifty million dollars and the amount thereof for the ensuing twenty years, as well as the operation's projected liability for general property taxes for the applicable period.

(3) The governing body of the local government shall adopt a resolution or ordinance which contains the total amount of taxes to be prepaid, the anticipated amounts and anticipated intervals of prepayments and credits for such prepayments, and the capital improvement or improvements upon which such prepaid taxes will be expended.

(4) The credit allowed in any taxable year for prepayments made under this article to or for each local government or any fund or account within the fund thereof shall be treated as an abatement of the property taxes due to such local government for that year from said operation and shall not affect the determination of the valuation for assessment thereof. The credit shall be shown on the tax statement for that year as it applies to each local government, fund, or fund account to which applied.
