Mine safety (MSHA)
Company-level in CA — for KLEINFELDER, not this location alone
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 KLEINFELDER 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. 5 citations · 1S&S · 5 contractor · $607 proposed / $607 paid.

Source: MSHA citation database. “Contractor” annotations indicate the cited party was on-site at the mine but not the mine’s operator -- responsibility attaches to the contractor LLC, not the mine’s owner. Section codes reference 30 CFR (the Mine Safety and Health regulations).

No NLRB unfair labor practice charges or union representation cases on file for KLEINFELDER. Verify directly with National Labor Relations Board →
Visa & labor certification (OFLC) — historical
Office of Foreign Labor Certification — labor condition applications for H-1B, H-2A, H-2B visa programs. Wage ratio = offered / prevailing wage. Historical data only: DOL ended OFLC Performance Data Disclosure publication in 2026, so the figures above reflect filings through the last ingested cycle and are not being refreshed. Treat as a historical snapshot, not a current signal.

No EPA inspections or formal enforcement actions on file for KLEINFELDER. Verify directly with Environmental Protection Agency →
Motor carrier safety (FMCSA)

About this data
This profile aggregates federal enforcement records on KLEINFELDER from every major federal compliance and enforcement source. 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.
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.
