Coal Mining| Draft Coal Bond Calculation Guidelines| Comment Period Closes October 20, 2025 |Public Meeting September 9, 2025

  • August 21 2025
DEQ is seeking public comment on a draft guidance document for determining performance reclamation bonds at coal mines. The guidance document will be used by DEQ to determine the appropriate level of performance reclamation bond to be held by DEQ, to ensure complete reclamation in the event a permittee is unable or unavailable to complete reclamation.

The Montana Strip and Underground Mine Reclamation Act (MSUMRA) requires DEQ to determine and adjust the amount of bond based on the estimated cost to the State to complete reclamation in accordance with a permittee’s reclamation plan. The draft bond guidance document reflects bonding best practices and ensures consistent and adequate bonds are held by DEQ. When completed, the bonding guidance document will be used, in part, for calculating the appropriate performance reclamation bond for each coal company doing business in Montana.

DEQ reviews coal mine permit and amendment applications, operations and reclamation as they relate to state law. DEQ’s role in mining regulation is to provide mine oversight, oversee compliance, establish adequate bond amounts and ensure the permittee appropriately reclaims the land after mine completion.
