Michigan Compiled Laws, Chapter 324. Natural Resources and Environmental Protection § 324.63211

Sec. 63211. (1) An operator shall maintain financial assurance during mining operations until the department determines that all reclamation has been completed and for a postclosure monitoring period as determined under section 63209(6) and (7),  1 except that financial assurance shall be released immediately upon termination of a mining permit under section 63207(2)(a). 2

(2) The financial assurance required under subsection (1) shall apply to all mining and reclamation operations subject to the mining permit and be sufficient to cover the cost to administer, and to hire a third party to implement, reclamation under the mining, reclamation, and environmental protection plan as well as necessary environmental protection measures, including remediation of any contamination of the air, surface water, or groundwater that is in violation of the mining permit. The financial assurance shall consist of a conformance bond, escrow, cash, certificate of deposit, irrevocable letter of credit, or other equivalent security, or any combination thereof, covering at least 75% of the total required amount. Financial assurance for the balance of the required total amount, if any, shall consist of a statement of financial responsibility.

(3) Every 3 years, or as the department considers necessary, a permittee shall update the statement of financial responsibility required under subsection (2) and shall adjust the conformance bond, escrow, cash, certificate of deposit, irrevocable letter of credit, or other security, as applicable, to assure that the financial assurance is sufficient for the purposes of subsection (2).

(4) The financial assurance mechanism required by this section may be satisfied in whole or in part by financial assurance provisions required by other parts of this act if those provisions address the remediation activities required under this part.

(5) Failure to provide financial assurance under this section constitutes grounds for the department to order immediate suspension of activities at a mining operation, including the removal of metallic product from the site, pursuant to section 63221.  3
