MSHA Civil Penalties Increase 2.6% Under Annual Inflation Adjustment

On January 10, 2025, the Department of Labor published a final rule (Federal Register) adjusting civil monetary penalties for inflation across all DOL agencies, including the Mine Safety and Health Administration. The rule amends 30 CFR Part 100 and applies a cost-of-living multiplier of 1.02598 based on the October 2024 Consumer Price Index for All Urban Consumers (CPI-U).

The Federal Civil Penalties Inflation Adjustment Act of 1990, as amended in 2015, requires annual penalty adjustments by January 15 each year using a formula tied to inflation. This year's 2.6% increase reflects the percentage change in CPI-U between October 2023 and October 2024. The adjustment is mandatory and exempt from notice-and-comment rulemaking under the Administrative Procedure Act.

For MSHA violations, the new penalty levels apply to citations issued after January 15, 2025 (the effective date). The rule does not change the substantive violations themselves or MSHA's penalty assessment methodology under 30 CFR Part 100—it simply increases the maximum and minimum penalty amounts proportionally. Specific new penalty levels for common MSHA violation categories are detailed in the regulatory text at 30 CFR 100.3 and related sections, though the Federal Register notice does not provide a side-by-side comparison table of old versus new amounts.

The rule affects all mining operators subject to MSHA enforcement. Because penalty calculations under the Part 100 matrix consider factors like operator size, violation history, and negligence, the practical impact varies by citation. Operators can expect slightly higher assessments for violations cited after January 15, 2025, even if the underlying conduct occurred before that date—the assessment date controls, not the violation date.

One implementation question remains unaddressed: whether pending contested citations (already issued but not yet finally assessed) will be recalculated using the new penalty levels if the final assessment occurs after January 15, 2025. MSHA's standard practice has been to apply the penalty schedule in effect at the time of final assessment, but the rule does not explicitly confirm this for 2025 adjustments. Operators with open contest proceedings should assume higher penalties if settlement or adjudication extends past mid-January.
