The first lease issued to an applicant under ORS 274.885 to 274.895 with respect to any submerged lands may allow the applicant six months in which to make a practical survey of the field which the applicant has leased, and another 12 months in which to erect a plant and commence operation. The lessee shall, within six months of the time of obtaining the lease, make or cause to be made a practical survey showing the amount and condition of kelp within the territory described in the lease, and shall file a copy of the survey with the Director of the Department of State Lands within six months. Upon the failure of the lessee so to do, the lease shall be canceled by the Department of State Lands.
