                    On December 27, 2010 (75 FR 81165), MSHA published a proposed rule, Examinations of Work Areas in Underground Coal Mines for Violations of Mandatory Health or Safety Standards. The proposal would require operators to examine for violations of mandatory health or safety standards in addition to hazardous conditions, and take corrective actions if violations are found. It would also require that operators review with mine examiners on a quarterly basis all citations and orders issued in areas where examinations are required. The proposal would require that underground coal mine operators find and fix violations of mandatory health or safety standards, thereby improving health and safety for miners. The proposed rule is available on MSHA's Web site at                     *http://www.msha.gov/​REGS/​FEDREG/​PROPOSED/​2010PROP/​2010-32410.pdf*.                

In response to a request from the public and to provide the opportunity for additional public participation in this rulemaking, MSHA is extending the comment period from February 25, 2011, to March 28, 2011. All comments and supporting documentation must be received or postmarked by 12 midnight Eastern Daylight Savings Time, March 28, 2011.
