ARSD 74:29:12:17. Review of calculated financial assurance amounts

The board may adjust financial assurance amounts at any time if the amounts inadequately cover current reclamation costs because of inflation or discount rate projections, unanticipated conditions, increases or decreases in disturbed or reclaimed acreage, and modifications made to the permit through permit amendments or technical revisions. Calculated financial assurance amounts may also be evaluated during the review of annual reports for each mine permit to determine whether the calculated amount adequately covers current reclamation costs and if any adjustments are needed.
