MACHINERY · DAYS AWAY FROM WORK ONLY
Accident narrative
EE was working in a shop location adjacent to some welding that was being done. EE received flash burn to their eyes because of this. EE was not able to work the next day due to this making this a Lost Time accident and therefor reportable to MSHA.
Regular Safety and Health Inspection · 14.5 on-site hours
56.14100(b) · $151.00 proposed
Regular Safety and Health Inspection · 25.0 on-site hours
SLIP OR FALL OF PERSON · DAYS RESTRICTED ACTIVITY ONLY
Accident narrative
EE was walking around a screening tower and said EE tripped over EE's own feet falling to the ground. EE reported this two weeks later stating EE's knee had swelling and discomfort. EE was treated, has a follow up and restrictions until then making this MSHA reportable. Ee was terminated on 09/24/2025 as a result of a separate company safety infraction.
Spot Inspection · 12.5 on-site hours

SLIP OR FALL OF PERSON · DYS AWY FRM WRK & RESTRCTD ACT
Accident narrative
EE was climbing into a manlift and got tangled up in the twin leg lanyard causing EE to fall and sprained right ankle in the process. EE was treated and written out of work the following day making this MSHA reportable.

Safety sources and definitions
MSHA Violations (issue date), Accidents (accident date), and Inspections (begin date). Snapshot 2026-10-13.
Counts describe published rows, including contractor records; accident records are not distinct incidents or numbers of people injured.
Zero means no matching records in the imported sources, not proof of no events. Historical coverage differs by source; absence before a source begins reporting is not a zero incident rate. Invalid or absent dates and records after the snapshot are excluded.
S&S means SIG_SUB=Y. Fatality records use DEGREE_INJURY_CD=01. Proposed penalties are not final assessed or paid amounts; missing dollar values are omitted.
Inspection hours are SUM_TOTAL_ON_SITE_HOURS attributed to the inspection start date, without supervisor/trainee hours. Missing hours are omitted; a started inspection may still be open.
Portfolio totals use current mine membership, including events before the current owner or operator's tenure.
CFR headings link to the current Title 30 index; they are not historical legal determinations.
OWNERSHIP
Operator and controller history
Current ownership comes from MSHA Mines. Historical start and end dates come from MSHA Controller and Operator History.

Silica and quartz
Coal quartz, metal/nonmetal personal samples and area samples. Snapshot Oct 13, 2026. 29 silica records across the mine’s published history.
Personal silica samples · concentration / limit
Quarterly mean · published C/E ratio
— No eligible measurements. * Quarter in progress. Means describe the available samples, not average exposure across the mine.
Quartz % is the sample’s quartz content; µg/m³ is its reported concentration. Personal C/E is the ratio to the limit published with that sample. Personal and area concentration units and void status are not specified in those source files.

Sources and interpretation
- Coal means use numeric concentrations from samples marked not voided, excluding control/invalid sample types and dates after the snapshot. Missing values remain null; reported zeroes remain zero.
- Quarterly means describe available samples, not mine-wide or worker-average exposure. Quarters with no eligible measurements remain empty; the current quarter is partial.
- Personal C/E is MSHA's published concentration-to-limit ratio. A value above 1 is not by itself a citation or a determination under the 2024 silica rule. Personal and area files do not publish a void-status field.
- Area records include bulk-dust analyses and are kept separate from personal exposure results. Their concentration units are not specified in the source dictionary.
- Missing samples do not establish safe conditions. Coal quartz percentage and concentration are separate measures. No compliance threshold is inferred for coal samples.

EIA production and cited regulations
EIA annual figures are reported separately from MSHA. Regulation links use the current eCFR snapshot.
Not present in the 2024 EIA coal workbook.
This can mean the operation is non-coal, inactive for the annual period, or outside the EIA-7A reporting population.
