The Office of Surface Mining (OSM) has been involved in a number of efforts related to coal slurry impoundments and underground mines since the breakthrough at the Martin County Coal Company impoundment in October 2000. A number of technical issues related to slurry impoundments have been identified, and OSM has been working with MSHA, the States and others to develop approaches to dealing with these issues. These responses include development of a report to Congress, planning for underground mine mapping projects, and continuing work on other technical documents. This presentation includes a review of these efforts, with a focus on interagency cooperation and the plans for the future.
