Wash. Rev. Code § 79.14.510
At any time during the life of the option contract, the holder thereof may apply to the department for a coal mining lease of the lands included therein, or such portion thereof as the holder may specify, for the purpose of mining and extraction of coal therefrom. Such coal mining lease shall be for such term, not more than twenty years, and in such form as may be prescribed by the department, shall entitle the lessee to mine and sell and dispose of all coal underlying said lands and to occupy and use so much of the surface thereof as may be necessary for bunkers and other outside works, and for railroads, buildings, appliances, and appurtenances in connection with the mining operations. Such lease shall provide for the payment to the state of a royalty, according to the grade of coal, for each ton of two thousand pounds of merchantable coal taken from the lands, as follows: For lignite coal of the class commonly found in Lewis and Thurston counties, not less than ten cents per ton; for subbituminous coal, not less than fifteen cents per ton; for high grade bituminous and coking coals, not less than twenty cents per ton; but such lease shall provide for the payment each year of a minimum royalty of not less than one nor more than ten dollars an acre for the lands covered thereby. However, the department may agree with the lessee that said minimum royalty shall be graduated for the different years of said lease so that a lower minimum royalty shall be paid during the earlier years of the term. The minimum royalty fixed in the lease shall be paid in advance each year, and the lessee, at stated periods during the term of the lease, fixed by the department, shall furnish to the department a written report under oath showing the amount of merchantable coal taken from the land during the period covered by such report and shall remit therewith such sum in excess of the minimum royalty theretofore paid for the current year as may be payable as royalty for the period covered by such report.
The department shall incorporate in every lease such provisions and conditions not inconsistent with the provisions of this chapter and not inconsistent with good coal mining practice as it deems necessary and proper for the protection of the state, and, in addition thereto, the department is empowered to adopt such rules, not inconsistent with this chapter and not inconsistent with good mining practice, governing the manner and methods of mining as in its judgment are necessary and proper.
