MSHA published final rules in the Federal Register on January 19, 2001. These rules deal with diesel particulate matter exposure for underground miners in both coal and metal/nonmetal mines. This page is your single source page to the rules for metal/nonmetal mines and the Regulatory Economic Analysis for these rules.

  • Controls Being Used to Reduce Diesel Particulate Matter Exposures in U.S. Underground Metal and Nonmetal Mines
    The U.S. Mine Safety and Health Administration (MSHA) conducted compliance assistance diesel particulate matter (DPM) sampling throughout the underground metal and nonmetal mining industry. Based on that sampling, MSHA identified mines that were having difficulty meeting the DPM limit. To provide further assistance, MSHA then visited approximately 60 of the mines that were experiencing difficulty complying with the DPM standard. As part of these visits, DPM exposures were measured and control technologies for DPM were observed and assessed. Controls consisted of ventilation, clean engines, environmental cabs, alternative fuels, diesel particulate filters (DPF), and work practices.

  • Alternative Fuels
    Several alternative fuels are available to reduce diesel particulate emissions. These include both bio-diesel based fuels and water emulsion fuels. When selecting an alternative fuel, a mine should check with the distributor to make sure the fuel is compatible with the mining operation, as their use can result in increased maintenance or a loss in equipment power.

    A useful guide to buying bio-diesel, including links to an interactive map of distributors in all 50 states is available from the National Biodiesel Board on their web site:

    They have also posted a list of marketers that are capable of supplying biodiesel anywhere in the country. The proximity of your potential biodiesel usage in relation to a marketers listed mailing address is not necessarily relevant to their supply logistics or price structure. We recommend that you contact several suppliers for product and price information.

  • NIOSH Listserve
    A list-server has been established by the diesel team at NIOSH, Pittsburgh in response to the expressed and obvious need for a means to disseminate and share information and experiences concerning the application of available technologies for the reduction of miner exposures to diesel particulate matter and gaseous emissions in underground mines.
  • Metal and Nonmetal Diesel Particulate Filter Selection Guide
    This Metal and Nonmetal Filter Selection Guide is the result of a joint effort of MSHA and the Diesel Team from NIOSH Pittsburgh Research Laboratory. The Selection Guide and the following Best Practices are under active development. They should not be viewed as an MSHA policy or requirement. MSHA welcomes any comments or suggestions on the information contained in these documents. MSHA also encourages the mining industry to share their experiences with diesel particulate filters.

  • Baseline DPM Sample Results
    This 1,194-sample dataset is MSHA'S final version of the baseline sampling for diesel particulate matter (DPM) in metal and nonmetal mines conducted from October 2002 through October 2003. MSHA conducted additional DPM baseline sampling after July 19, 2003 in response to mine operators' concerns that some mines were either not in operation or were implementing major changes to ventilation systems during the original baseline period. This revised dataset includes DPM samples from seasonal and intermittent mines, and mines that were either under-represented, or unrepresented, in the original 874 dataset.
