United States Mine Safety & Health Administration – Establishing new health standards to manage DPM

On January 19, 2001, the United States Mine Safety & Health Administration (MSHA) published a final rule addressing the health hazards to underground miners from exposure to diesel particulate matter (DPM). The rule established new health standards for these miners by requiring, among other things, mine operators to use engineering and work practice controls to reduce DPM. MSHA projected that the mining industry would meet the final concentration limit in their mines through the use of things such as diesel particulate filtration devices or ventilation changes.
