Mine safety (MSHA)
Company-level in CA — for MP Materials Corp. / DE, 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 MP Materials Corp. / DE 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. 100 citations · 40S&S · $168,883 proposed / $153,115 paid.

About this data
This profile aggregates federal enforcement records on MP MINE OPERATIONS LLC 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 MP Materials Corp. / DE.
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.
