Description

Proposed rule; request for comments; notice of public hearings on 3 August 2023 in Arlington, Virginia and 21 August 2023 in Denver, Colorado - The Mine Safety and Health Administration (MSHA) proposes to 
amend its existing standards to better protect miners against 
occupational exposure to respirable crystalline silica, a carcinogenic 
hazard, and to improve respiratory protection for all airborne hazards. 
MSHA has preliminarily determined that under the Agency's existing 
standards, miners at metal and nonmetal mines and coal mines face a 
risk of material impairment of health or functional capacity from 
exposure to respirable crystalline silica. MSHA proposes to set the 
permissible exposure limit of respirable crystalline silica at 50 
micrograms per cubic meter of air ([micro]g/m\3\) for a full shift 
exposure, calculated as an 8-hour time-weighted average, for all 
miners. MSHA's proposal would also include other requirements to 
protect miner health, such as exposure sampling, corrective actions to 
be taken when miner exposure exceeds the permissible exposure limit, 
and medical surveillance for metal and nonmetal miners. Furthermore, 
the proposal would replace existing requirements for respiratory 
protection and incorporate by reference ASTM F3387-19 Standard Practice 
for Respiratory Protection. The proposed uniform approach to respirable 
crystalline silica occupational exposure and improved respiratory 
protection for all airborne hazards would significantly improve health 
protections for all miners and lower the risk of material impairment of 
health or functional capacity.
