(a)(1) When any land must be sold for payment of delinquent county taxes only, it shall be sold under this part and parts 20 and 24 of this chapter so far as they apply.

(2) It is the duty of the clerk of the court ordering the sale to bid, on behalf of the governmental entities for which the taxes are owing, to ascertain the amount due for taxes, interest, penalties and costs, where no other bidder offers the same or higher bid; provided, that, in the case of property where the county legislative body has determined that no bid should be made on behalf of the governmental entities to which taxes are owing due to a determination that such property poses an environmental risk or has financial liabilities associated with the property such that it is not in the best interest of the county to take possession of the property, the clerk shall not offer a bid. The county legislative body may also make a determination that no bid shall be made on behalf of the governmental entities on nonbuildable or nonconforming parcels, including, without limitation:

(3) The proceeds from such sale shall be applied, first, to the payment of the penalty allowed as compensation for prosecuting the suits; second, to the costs; and third, the remainder shall be prorated, first, to the county and, second, to any municipality that has a tax lien thereon.
