(1) Valuable materials may be sold separately from the land as a "lump sum sale" or as a "scale sale."
(a) "Lump sum sale" means any sale offered with a single total price applying to all the material conveyed.
(b) "Scale sale" means any sale offered with per unit prices to be applied to the material conveyed.
(2) Payment for lump sum sales must be made as follows:
(a) Lump sum sales under five thousand dollars appraised value require full payment on the day of sale.

(3) Except for sales paid in full on the day of sale or sales with adequate bid bonds, an initial deposit not to exceed twenty-five percent of the actual or projected purchase price shall be made on the day of sale.
(a) Sales with bid bonds are subject to the day of sale payment and replacement requirements prescribed by RCW
79.15.110.
(b) The initial deposit must be maintained until all contract obligations of the purchaser are satisfied. However, all or a portion of the initial deposit may be applied as the final payment for the valuable materials in the event the department determines that adequate security exists for the performance or fulfillment of any remaining obligations of the purchaser under the sale contract.
(4) Advance payments or other adequate security acceptable to the department is required for valuable materials sold on a scale sale basis or a lump sum sale not requiring full payment on the day of sale.
(a) The purchaser must notify the department before any operation takes place on the sale site.
(b) Upon notification as provided in (a) of this subsection, the department must require advanced payment or may allow purchasers to submit adequate security.
(c) The amount of advanced payments or security must be determined by the department and must at all times equal or exceed the value of timber cut and other valuable materials processed or removed until paid for.
(d) Security may be bank letters of credit, payment bonds, assignments of savings accounts, assignments of certificates of deposit, or other methods acceptable to the department as adequate security.

(b) The specified period for stone, sand, gravel, fill material, or building stone may not exceed thirty years.

79.150 RCW.
(6) The department may extend a contract beyond the normal termination date specified in the sale contract as the time for removal of valuable materials when, in the department's judgment, the purchaser is acting in good faith and endeavoring to remove the materials. The extension is contingent upon payment of the fees specified below.
(a) The extended time for removal shall not exceed:
(i) Forty years from date of purchase for stone, sand, gravel, fill material, or building stone;
(ii) A total of ten years beyond the original termination date for all other valuable materials.
(b) An extension fee fixed by the department will be charged based on the estimated loss of income per acre to the state resulting from the granting of the extension plus interest on the unpaid portion of the contract. The board must periodically fix and adopt by rule the interest rate, which shall not be less than six percent per annum.
(c) The sale contract shall specify:
(i) The applicable rate of interest as fixed at the day of sale and the maximum extension payment; and
(ii) The method for calculating the unpaid portion of the contract upon which interest is paid.
(d) The minimum extension fee is fifty dollars per extension plus interest on the unpaid portion of the contract.
(e) Moneys received for any extension must be credited to the same fund in the state treasury as was credited the original purchase price of the valuable material sold.
(7) The department may, in addition to any other securities, require a performance security to guarantee compliance with all contract requirements. The security is limited to those types listed in subsection (4) of this section. The value of the performance security will, at all times, equal or exceed the value of work performed or to be performed by the purchaser.
(8) The department does not need to comply with the provisions of this chapter for forest biomass except as described in the provisions of chapter
79.150 RCW. Forest biomass may not be included in any sales contract authorized under this chapter unless the department has complied with the provisions of chapter
79.150 RCW.
(9) The provisions of this section apply unless otherwise provided by statute.
