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

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. 1 case · $0 in backwages · 1 worker affected

Source: DOL WHD enforcement database. Cases shown reflect those the agency has closed and made public. A violation count is the agency’s tally of cited violations (one violation can affect many workers); the workers column counts distinct employees the agency found to be affected.

Company-level in CA — for MATRIX SERVICE CO, 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 MATRIX SERVICE CO operations in the same state.

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. 9 citations · 9 contractor · $1,008 proposed / $825 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).
