Department of Labor Wage & Hour Division — minimum-wage, overtime, child-labor, FMLA, and prevailing-wage enforcement.

Wage and hour breakdown by law

Per-statute totals across all closed DOL Wage & Hour cases against this employer. Backwages reflect amounts the agency assessed; civil penalty is the separate fine where applicable. Some acts (Davis-Bacon, SCA, CWHSSA, H-2B, CCPA) don't carry a civil penalty field in DOL's data. 2 statutes · 59 violations · $11,965 in backwages

Wage and hour cases

Closed DOL Wage & Hour Division cases (FLSA, FMLA, H-2B, MSPA, and related statutes). Backwages reflect amounts the agency assessed; civil penalty (CMP) is a separate fine levied on top, where the statute provides for one (FLSA / H-1B / H-2A / MSPA / FMLA / EPPA / FLSA Child Labor; other acts have no CMP column in DOL’s data). The Statutes column lists which laws each case cited. 2 cases · 59 violations · $11,965 in backwages · 50 workers affected

Mine safety (MSHA)

Company-level in ID — for Knife River Corp, not this location alone

Violations
80
Assessed penalties
$12,393

Mine Safety & Health Administration — citations issued at mining operations. MSHA records cases at the company/regional level (no worksite address), so these are matched by company name and state and may span other Knife River Corp operations in the same state.

MSHA citations

Mine Safety and Health Administration citations. S&S (significant and substantial) marks violations that could reasonably contribute to a serious injury. Negligence rating is MSHA’s operator-culpability assessment (none, low, moderate, high, or reckless disregard). Proposed = assessed at issuance; Paid = post-settlement / appeal. 80 citations · 23S&S · 80 contractor · $12,393 proposed / $12,393 paid.

About this data

This profile aggregates federal enforcement records on Knife River Corporation from every major federal compliance and enforcement source plus the UVA Corporate Prosecution Registry. OSHA workplace safety inspections, WHD wage cases, MSHA mine safety, EPA environmental enforcement, NLRB labor relations, OFLC visa/labor certification, FMCSA motor carrier registration, SAM.gov debarments, CMS nursing-home records, BLS industry safety benchmarks, OSHA ITA self-reported injury rates, SEC enforcement and financial disclosures, CPSC and NHTSA recalls.

Establishments are matched across agencies using normalized employer name, state, and ZIP code. This establishment resolves to the parent rollup Knife River Corp, which operates 192 establishments in our dataset.

OSHA citations typically appear 3–8 months after the inspection, so very recent enforcement actions may not yet be reflected. Profiles may be incomplete if the establishment operates under multiple legal names or files under variations our entity-matching rules don’t yet cover.
