Summary
The federal government is proposing new rules to limit the amount of diesel exhaust that underground metal and nonmetal miners are exposed to on the job. This aims to protect workers from harmful pollutants that can cause serious respiratory diseases and cancer.
Key Points
- 1The rule sets new limits on diesel particulate matter (soot and chemicals from diesel engines) that miners can breathe while working underground
- 2It applies to workers in underground mines that extract metals like copper and gold, as well as nonmetal materials like salt and phosphate
- 3Mine operators will need to install or upgrade ventilation systems and equipment to reduce diesel engine emissions and protect worker health
- 4The public has until August 1, 2025, to submit comments and feedback on the proposed rule before it becomes final
- 5Stricter controls could increase mining company costs but are expected to prevent thousands of cases of lung disease and other illnesses among miners
