Compliance Deadline for M/NM Mines to Comply with Silica Rule (under review)
The silica rule as published sets the compliance deadline for m/nm mines as April 8, 2026. But, status of the silica rule is unclear in light of (1) current case bending before 8th Circuit and (related) (2) signals from the Department of Labor that they are exploring modifications to the rule as originally published
D.C. Circuit hearing date for oral argument in Crimson Oak Grove aka "Secretary's settlement authority" case
D.C. Circuit is set to review several FMSHRC decisions purporting to limit the Secretary of Labor's power unilaterally to settle administrative actions without FMSHRC approval. Oral argument set for February 12, 2026
Eighth Circuit deadline to file status reports in Sorptive Minerals aka "silica rule" case
The case challenging the silica rule is currently in abeyance while the parties seek to resolve the dispute over the rule. The 8th Circuit has directed the parties to file periodic status reports with the court, and the next due date is February 2, 2026.
DOL files status report with court stating that MSHA is still negotiating a revise version of the silica rule
As directed by the court, the Secretary of Labor filed a status report before the February 2 deadline. In a brief status report, the Secretary stated that negotiations with industry groups continue, but providing no additional details, stating only that the Department "continues to engage in limited rulemaking to reconsider and seek comments on portions of the Silica Rule impacted by this appeal"
Commission DENIED U.S. Aggregates default after five-month delay filing motion to reopen—inadequate explanation of personnel change and failure to account for prolonged inaction proved fatal
Commission denied U.S. Aggregates' motion to reopen after five-month delay between discovering missed penalty deadline and filing. Routine application of excusable neglect standards—vague personnel change explanation and prolonged inaction proved fatal.
Commission REOPENED Wyo-Ben penalty default after assessment disappeared in internal mail handling—operator's quick response after discovering error through MSHA database check satisfied good-faith mistake standard
Commission reopened Wyo-Ben penalty default after assessment disappeared in internal mail handling. Operator's proactive MSHA database monitoring and quick response (28 days) demonstrated good faith—reinforces that systematic database checking can save defaults.
D.C. Circuit upholds FMSHRC's authority to refuse to reopen petition to challenge assessment
Commission abandons flawed Peabody S&S test and returns to statutory text: violations now trigger enhanced penalties if they 'could significantly and substantially contribute' to hazards—lowers enforcement threshold for all operations.
The Commission issued a major doctrinal shift in how significant and substantial (S&S) violations are evaluated under section 104(d)(1) of the Mine Act. For decades, the Commission applied the Mathies/Peabody four-step test requiring proof that a violation was 'reasonably likely to cause' a hazard and 'reasonably likely' to result in 'reasonably serious injury.' The Commission now holds this test impermissibly deviated from the Mine Act's plain language, which requires only that a violation 'could significantly and substantially contribute to the cause and effect' of a hazard. The new standard eliminates the 'reasonably likely' requirement at Step 2 and refocuses the analysis on whether the violation contributes to exposure to danger, not whether injury is likely. The Commission affirmed two S&S citations—one for a missing longwall shield pin (projectile hazard) and one for cracked light globes on a continuous miner (ignition hazard)—under the corrected standard. This decision fundamentally changes S&S litigation and enforcement across all mining sectors. Operators can expect MSHA to designate more violations as S&S because inspectors need only show the violation 'could contribute' to a hazard, not that the hazard is 'reasonably likely' to occur or cause injury. This lower threshold means more citations will carry enhanced penalties, and operators will face increased risk of pattern-of-violations (POV) designations triggering withdrawal orders. The decision explicitly rejects 40 years of Commission precedent and aligns with Congress's 1977 intent that 'all except purely technical violations' should be S&S. Operators should immediately review citation-contesting strategies, reassess POV risk exposure, and anticipate higher S&S rates in future inspections.
Commission clarifies Federal Rule 6(a) extends contest deadline through next business day when thirtieth day falls on weekend or federal holiday—Veterans Day extension saved Consol's November 11 filing from finality
Commission held Federal Rule 6(a) extends contest deadlines through the next business day when the 30th day falls on a weekend or federal holiday. Operators filing on the holiday itself (rather than waiting for next business day) are timely—confirms conservative deadline practices provide safety margin.
Highwall examination standard expanded: Viewing from below insufficient—surface coal operations must examine highwalls from vantage points capable of detecting all fall hazards threatening active work areas
Commission held highwall examinations must assess conditions from vantage points capable of detecting all fall hazards—viewing from below is insufficient. All surface operations with highwalls must update examination procedures immediately.
original compliance deadline for coal mines to comply with silica rule (under review)
The silica rule as published sets the compliance deadline for m/nm mines as April 14, 2025. But, MSHA is not enforcing the rule pending resolution of the challenge currently before 8th Circuit.
