(a) Exclusive Commercial and Non-exclusive Scientific Fossil Removal Permits may be issued on state lands with the approval of the Board. The terms of these permits shall cover the conditioned removal of all fossil forms with the exclusion of dinosaur and all other vertebrate fossils not specifically named in these rules and the Board's permit form, for which no commercial permit is obtainable. Permits shall be of five (5) years duration. Permits may be renewed upon application, for successive five (5) year periods, on the permit form then in effect. Exclusive Commercial Fossil Removal Permits may not exceed ten (10) acres in size, but the calculation of this acreage shall not include access roads into a permit. Approval of renewals of ongoing Exclusive Commercial Fossil Removal Permits will not be withheld so long as the permits are in good standing.
