(1) For the purposes of this section, "wood biomass fuel" means a pyrolytic liquid fuel or synthesis gas-derived liquid fuel, used in internal combustion engines, and produced from wood, forest, or field residue, or dedicated energy crops that do not include wood pieces that have been treated with chemical preservatives such as creosote, pentachlorophenol, or copper-chrome-arsenic.
(2)(a) All buildings, machinery, equipment, and other personal property which is used primarily for the manufacturing of wood biomass fuel, the land upon which this property is located, and land that is reasonably necessary in the manufacturing of wood biomass fuel, but not land necessary for growing of crops, which together comprise a new manufacturing facility or an addition to an existing manufacturing facility, are exempt from property taxation for the six assessment years following the date on which the facility or the addition to the existing facility becomes operational.
(b) For manufacturing facilities which produce products in addition to wood biomass fuel, the amount of the property tax exemption is based upon the annual percentage of the total value of all products manufactured that is the value of the wood biomass fuel manufactured.
(3) Claims for exemptions authorized by this section must be filed with the county assessor on forms prescribed by the department of revenue and furnished by the assessor. Once filed, the exemption is valid for six years and may not be renewed. The assessor must verify and approve claims as the assessor determines to be justified and in accordance with this section. No claims may be filed after December 31, 2015.
The department of revenue may promulgate such rules, pursuant to chapter 34.05
