"Possessory interests" means the following:
A use of property or improvements that does not contain one of the elements in subparagraphs (A) to (F), inclusive, shall be rebuttably presumed to be a nonexclusive use.
Any possessory interest may, in the discretion of the county board of supervisors, be considered as sufficient security for the payment of any taxes levied thereon and may be placed on the secured roll.
Leasehold estates for the production of gas, petroleum and other hydrocarbon substances from beneath the surface of the earth, and other rights relating to these substances which constitute incorporeal hereditaments or profits a prendre, are sufficient security for the payment of taxes levied thereon. These estates and rights shall not be classified as possessory interests, but shall be placed on the secured roll.
If the tax on any possessory interest or leasehold estate for the production of gas, petroleum and other hydrocarbon substances is unpaid when any installment of secured taxes become delinquent, the tax collector may use those collection procedures which are available for the collection of assessments on the unsecured roll.
If the tax on any possessory interest or leasehold estate for the production of gas, petroleum and other hydrocarbon substances remains unpaid at the time set for the declaration of default for taxes carried on the secured roll, the possessory interest tax together with any penalty and costs which may be accrued thereon while on the secured roll shall be transferred to the unsecured roll.
