Reviser's note: Chapter 64, Laws of 1970 ex. sess. has been codified as chapter 78.44 RCW, "Mines, minerals, and petroleum" although section 1 of the act states "Sections 2 through 25 of this act shall constitute a new chapter in Title 76 RCW." As the act pertains solely to surface mining, the change in placement has been made to preserve the subject matter arrangement of the code.
