It is the intention of the general assembly that the maximum use be made of all carryforward provisions in the Internal Revenue Code. Therefore, if the aggregate principal amount of bonds, subject to section 146 of the Internal Revenue Code, issued by all political subdivisions in a calendar year is less than the state ceiling for that calendar year, a political subdivision may apply to the governor’s designee for an allocation of a specified portion of the excess state ceiling to be applied to a specified carryforward project. The governor’s designee shall determine the time and manner in which applications for an allocation of excess state ceiling shall be made for this purpose and may, in the designee’s discretion, refuse any requests. However, the procedures for applications, the method of identifying, and the types permitted of carryforward projects shall comply with the carryforward provisions of the Internal Revenue Code and regulations promulgated under those provisions.
