2. **COMPLIANCE — 5 since 2021:** Violations and penalties 342 violation rows across the full record; 135 carry an S&S flag and $62,164 appears in current assessed amounts.
3. **HEALTH — 665 samples:** Occupational health samples 520 coal dust; 34 coal quartz; 111 noise. 0 personal-sample rows have a published C/E ratio above 1; 5 noise rows have an action-level or PEL dose above 100%. These are separate measures, not a silica exceedance count. Silica results and sample status are shown separately.
4. **PRODUCTION — 148K tons:** Quarterly production and employment 37K employee hours and 59 summed average employees across reported subunits in the latest published quarter.
5. **LEGAL — 30 linked rows:** Contests, conferences and decisions 10 contested-violation rows, 12 civil-penalty docket/decision rows, and 8 conference records linked by issuance number.
6. **CONTRACTORS — 2 linked entities:** Contractors Contractors are linked through this mine’s violation or accident records. Their production and hours cover all their operations, so they are not included in this mine’s totals.
7. **INSPECTIONS — 7 since 2021:** Inspections 197 inspection events and 5K published inspection hours across the historical record.

- This is public-record decision support, not legal advice or an official MSHA record.
- Missing data can indicate no event, publication delay, an unresolved identity, or inapplicability.
- Contractor production data is entity-level and is not attributed to this mine.
