Mine Safety and Health Administration May 22, 2007 – Federal Register Recent Federal Regulation Documents

The Mine Safety and Health Administration (MSHA) is issuing an emergency temporary standard (ETS) under section 101(b) of the Federal Mine Safety and Health Act of 1977 in response to the grave danger that miners face when underground seals separating abandoned areas from active workings fail. MSHA has concluded from its investigations of mine explosions that occurred and other recent reports, that additional immediate action is necessary to protect miners. This ETS includes requirements to strengthen the design, the construction, the maintenance, and the repair of seals, as well as requirements for sampling and controlling atmospheres behind seals. It also increases the level of overpressure for new seals, thus implementing the requirements of the Mine Improvement and New Emergency Response (MINER) Act of 2006.
