Significant and Substantial Test: Commission Revisits Four Decades of S&S Jurisprudence, Signals Potential Return to Statutory Text

The Holding

The Commission affirmed two significant and substantial citations issued to Consol Pennsylvania Coal Company—one for a missing horizontal keeper pin on a longwall shield (30 C.F.R. § 75.1725(a)) and one for cracked light globes on a continuous miner (30 C.F.R. § 75.503). While affirming the citations under the current Peabody test, a majority of Commissioners used this decision to announce fundamental problems with the Commission's S&S jurisprudence, specifically criticizing the Peabody reformulation of Mathies as inconsistent with the Mine Act's statutory language. This creates new law by signaling the Commission's willingness to reconsider the S&S standard and affects all underground coal operations subject to S&S designations.

How This Case Got Here

Following a March 2021 MSHA spot inspection at the Bailey Mine, Inspector Walter Young issued two S&S citations: one for a missing horizontal keeper pin designed to retain a vertical shear pin in a longwall shield, and one for four cracked light globes on a continuous miner in a gassy mine. The ALJ affirmed both citations, the S&S designations, and the civil penalties. Consol appealed, challenging the violation findings, negligence designations, gravity findings, and S&S determinations. The Commission granted review.

Key Reasoning

On the substantive violations, the Commission affirmed based on substantial evidence supporting the ALJ's findings. For the pin violation, the Commission credited the inspector's testimony that vertical shear pins break frequently (at least once per shift) and can become projectiles when unsecured by the horizontal keeper pin, with documented instances of miner injury. For the globes violation, the Commission found the mine's liberation of over 10 million cubic feet of methane per 24 hours, combined with an improperly calibrated methane monitor, created conditions where cracked explosion-proof enclosures posed a reasonable ignition hazard.

However, the decision's significance lies in its extended discussion of S&S jurisprudence. Commissioners Baker and Marvit conducted a comprehensive historical analysis concluding that the current Peabody test conflicts with Section 104(d)(1)'s statutory language. The Commission traced S&S interpretation from the 1965 Federal Coal Mine Safety Act Amendments through National Gypsum (1981), Mathies (1984), Musser (2010), Newtown (2016), and Peabody (2020), finding that 'four decades of tinkering has resulted in an awkward and cumbersome standard divorced from the statutory text.'

'The Mine Act is the Commission's lodestar and, where our jurisprudence has become contrary or inconsistent with the Act, it is incumbent upon us to return to the language of the Act and Congress's intent in drafting it.'

The Commission identified four specific problems with Peabody: (1) Step 2 requires proving the violation would 'cause' the hazard rather than 'contribute to' it as the statute requires; (2) Steps 3 and 4 improperly focus on 'injury' when the statute addresses only 'hazards'; (3) the test impermissibly injects 'reasonable likelihood' language nowhere found in the Mine Act; and (4) the Peabody standard effectively collapses the S&S designation into the higher 'imminent danger' standard, contradicting Congress's graduated enforcement scheme.

Arguments on Appeal

What Worked: The Secretary successfully defended both citations by presenting credible inspector testimony about past incidents and known hazards. For the pin violation, testimony about frequent shear pin failures and documented miner injuries from projectiles proved persuasive. For the globes violation, evidence of the mine's extreme methane liberation and the improperly calibrated monitor established the ignition hazard. The Commission emphasized its deference to ALJ credibility determinations and the principle that operators cannot assume miners will always follow safety procedures.

What Failed: Consol's arguments that violations were unlikely to cause injury because miners would follow company policies (staying two shields away) or because LED bulbs are 'nearly intrinsically safe' were rejected. The Commission found these arguments rested on improper assumptions about perfect miner behavior and unproven safety claims. Consol's challenge to the inspector's credibility likewise failed, as the Commission will not overturn an ALJ's credibility findings absent 'compelling reasons.' The operator's attempt to argue no S&S because the hazard was not 'reasonably likely' ironically highlighted the very problem with Peabody the Commission was signaling it may reconsider.

What This Means

For Settlement: Immediate impact is limited because the Commission affirmed both citations under existing Peabody standards. However, the extensive criticism of Peabody signals potential future changes that could make S&S designations easier to establish (returning to a 'contribution to hazard' standard rather than 'reasonably likely to cause injury'). Operators facing S&S citations should preserve arguments about the proper statutory standard.

For Contest Strategy: This decision provides ammunition for challenging Peabody's application in future cases. Operators can argue the Commission itself has identified fundamental flaws in the current test. However, until the Commission formally overrules Peabody, ALJs remain bound by it. The decision's discussion of what constitutes 'substantial evidence' for credibility findings also counsels that attacking inspector testimony is rarely successful.

For Client Advisory: The substantive holdings on the pin and globe violations establish that: (1) missing safety components that secure equipment under stress constitute violations even absent immediate hazard manifestation; (2) the 'reasonably prudent miner' standard looks to whether a knowledgeable person would recognize the hazard; (3) gassy mines (over 10 million cubic feet/24 hours) face heightened scrutiny for permissibility violations; and (4) 'nearly intrinsically safe' is not a recognized standard. Operators should review examination procedures for longwall shields and prioritize replacement of damaged light globes in high-methane areas.

For Pending Matters: Cases involving S&S designations should preserve arguments that Peabody conflicts with the Mine Act. The Commission's detailed statutory analysis provides a roadmap for challenging the current standard, though the timing of any formal change remains unclear. Appeals to circuit courts may now cite the Commission's own concerns about Peabody's statutory basis.

What Remains Unclear

The Commission's critique of Peabody raises more questions than it answers: Will the Commission formally overrule Peabody and Newtown, and if so, when? What standard would replace them—a return to Musser, Mathies, or something closer to the statute's text? The Commission endorsed Congress's approval of the broad Alabama By-Products standard (any non-technical violation is S&S) but did not adopt it, leaving the appropriate test uncertain. Chair Jordan did not join the majority opinion, creating ambiguity about whether three votes exist for changing the standard. Most importantly, whether the suggested statutory interpretation survives circuit court review remains to be determined.

What We're Monitoring

  • Whether the Commission issues a follow-up decision formally overruling or modifying Peabody, or whether this extensive dicta remains just that—non-binding criticism
  • How ALJs apply this decision: will they continue applying Peabody strictly, or will the Commission's concerns influence S&S findings?
  • Whether MSHA modifies its S&S designation practices in response to the Commission's statutory interpretation discussion
  • Potential circuit court review if an operator appeals specifically on the Peabody standard's statutory basis, now armed with the Commission's own analysis
