Sealing of Abandoned Areas
The Mine Safety and Health Administration (MSHA) is reopening the comment period for the Emergency Temporary Standard (ETS) on sealing of abandoned areas of underground coal mines to provide commenters time to review and submit comments on the U.S. Army Corps of Engineers' Draft Report "CFD [Computational Fluid Dynamics] Study and Structural Analysis of the Sago Mine Accident" (Report).
