020-6 Wyo. Code R. § 6-7
(a) An operator conducting an existing, ongoing operation may at any time submit to the Administrator an application to self-bond. The application shall contain all information required in Section 2 of this Chapter except Section 2(a)(ii) shall read: "Amount of bond required to be determined in accordance with W.S. § 35-11-417(c)(ii)."
(b) If the Administrator determines that the operator qualifies for self-bonding, then the operator shall execute all required agreements or instruments and sign a new bond payable to the State of Wyoming which covers all periods of time as they relate to the mining operation. At this time, the prior bond shall be released. This release shall not be governed by any requirements as to the release of bonds which occur upon completion in whole or in part of the reclamation program.
(c) Any operation which holds a self-bond on the effective date of this Chapter shall be presumed to meet the requirements of this Chapter. To continue the self-bond, within one year from the effective date of this Chapter an application for a renewal self-bond shall be filed with the Administrator which meets all requirements in Section 3. A new indemnity agreement shall be executed which includes the requirements in Section 4(b).
