Md. Code, Environment § 15-826

No permittee may conduct surface mining within the State if the permittee previously has forfeited any bond posted pursuant to surface mining activities, unless on application the permittee repays the Department the cost of reclamation if the Department had reclaimed the land, plus interest at the rate set as § 11-107(a) of the Courts and Judicial Proceedings Article provides, for the time elapsed, less the amount of the forfeited bond. If the land is still unreclaimed, the permittee shall reclaim the land covered by the forfeited bond at the permittee’s expense, including any additional erosion, sedimentation, or pollution damage resulting from the lack of proper reclamation during the interim.
