The modification to the mining plan will add approximately 590 ac. to the approved mining plan area for the underground mine, and will allow mining of approximately 2.7 million t of Federal coal. The action will add approximately 3 - 4 years to the life of the mine.

The mine is projected to produce, on average, 1.07 million tpy, with a maximum production rate of 1.3 million tpy. The mine currently employs 88 people.

The King II Mine permit provides for a post-mine land use of rangeland and wildlife habitat which will continue with this modification.

OSMRE holds a reclamation performance bond in the amount of US$32 555 on the site. Reclamation performance bonds are held to ensure that post-mining reclamation of the site is carried out if a company cannot carry out its legally required reclamation obligations.
