What the agency says
MSHA is eliminating outdated requirements for diesel particulate matter (DPM) emission limits for permissible diesel-powered equipment and non-permissible heavy-duty diesel-powered equipment operated in underground coal mines. These requirements are being removed from MSHA's regulations because they contain outdated effective dates that are no longer applicable.
