A grant is effective after both you and the BLM sign it. You must accept its terms and conditions in writing and pay any necessary rent and monitoring fees as set forth in subpart 2806 of this part and § 2805.16 of this subpart. Your written acceptance constitutes an agreement between you and the BLM that your right to use the public lands, as specified in the grant or lease, is subject to the terms and conditions of the grant or lease and applicable laws and regulations.
