The final rule follows extensive public feedback and multiple hearings held in August. MSHA’s findings support the dangers of silica dust exposure, which can lead to lung cancer, emphysema, chronic bronchitis, and other serious health conditions.
Engineering and Administrative Controls
To comply with the new standards, mine operators must adopt engineering control methods like installing ventilation systems or dust collectors, as well as administrative measures to reduce silica exposure. Additionally, mine operators must conduct sampling, report incidents of overexposure, and take immediate corrective action.
MSHA noted the rule would prevent about 1,000 deaths and thousands of illnesses linked to silica exposure. A further action level of 25 micrograms per cubic meter will prompt increased monitoring when exceeded.
DOL Finalizes Rule To Curb Miners’ Exposure To Silica Dust : Opposition from Industry
Some industry representatives have voiced concerns over the rule. Rep. Virginia Foxx, R-N.C., criticized the new regulations as “unworkable” and accused the DOL of economic illiteracy. However, Ashley Burke, spokesperson for the National Mining Association, stated the association supports the new limits and remains committed to improving miners’ health and safety.
