The department may issue permits waiving portions of this chapter and specifying conditions under which regulated material may be imported from the quarantine area in the following situations:

(1) The material is Corylus planting stock being imported by Washington State University or USDA for experimental or trial purposes; or

(2) No more than twenty-five plants are being imported by a grower as source material for micropropagation, and these plants will be isolated and held until the department determines them to be free of Anisogramma anomala. As a condition of the permit, the permit holder may be required to hold these source plants in an enclosed facility during the micropropagation process and to destroy them upon its completion.
