What is an RFI?

A Request for Information (RFI) generally describes a problem or an issue of Agency interest and requests data, comments, and other information from the public relevant to the problem presented. Responses to the RFI will assist the Agency in determining an appropriate course of action--which may or may not involve rulemaking--to address the problem.

Refuge Alternatives for Underground Coal Mines, Request for Information [08/08/2013]

Published 08/08/2013
SUMMARY: The Mine Safety and Health Administration (MSHA) is requesting data, comments, and information on issues and options relevant to miners' escape and refuge that may present more effective solutions than the existing rule during underground coal mine emergencies. The Agency continues to reiterate that in the event of an underground coal mine emergency, a miner should seek escape as the first line of defense. Responses to this Request for Information (RFI) will assist MSHA in determining if changes to existing practices and regulations would improve the overall strategy for survivability, escape, and training to protect miners in an emergency. MSHA will review the comments to determine what actions, if any, the Agency will take in response to comments.

Published 08/30/2006
SUMMARY: On June 15, 2006, the Mine Improvement and New Emergency Response (MINER) Act of 2006 was enacted. In accordance with Section 2 of the MINER Act, each underground coal mine operator must submit an emergency response plan (ERP) to the appropriate MSHA District Manager. The ERP provides for the evacuation of all individuals endangered by an emergency and also for the maintenance of individuals trapped underground in the event that miners are unable to evacuate the mine. MSHA is soliciting comments that address the availability of readily accessible breathable air that would be sufficient to maintain miners trapped underground over a sustained period of time. MSHA will consider these comments in developing guidance to assist in assuring that the ERPs provide safe and reliable post-accident breathable air supplies for trapped miners.

Published 01/25/2006
SUMMARY: The Mine Safety and Health Administration is requesting data, comments, and other information on issues relevant to underground mine rescue equipment and technology. Over the last several years, improvements have been made to communication devices, sensors and other forms of technology in general industry. As such, continuous development and deployment of mine rescue equipment and technology are crucial to enhancing the effectiveness of mine rescue operations and improving miners' survivability in the event of a mine emergency. Responses to this request for information will assist the Agency in determining an appropriate course of action as necessary to improve mine rescue capabilities.
