For the purposes of this chapter and RCW
76.13.150 and
77.12.755, "small forestland owner" means an owner of forestland who, at the time of submission of required documentation to the department, has harvested from his or her own lands in this state no more than an average timber volume of two million board feet per year during the three years prior to submitting documentation to the department and who certifies that he or she does not expect to harvest from his or her own lands in the state more than an average timber volume of two million board feet per year during the ten years following the submission of documentation to the department. However, any landowner who exceeded the two million board feet annual average timber harvest threshold from their land in the three years prior to submitting documentation to the department, or who expects to exceed the threshold during any of the following ten years, shall still be deemed a "small forestland owner" if he or she establishes to the department's reasonable satisfaction that the harvest limits were, or will be, exceeded in order to raise funds to pay estate taxes or for an equally compelling and unexpected obligation, such as for a court-ordered judgment or for extraordinary medical expenses.
