About this data

This profile aggregates federal enforcement records on CALPORTLAND COMPANY 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 CalPortland, which operates 24 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. To report a missing record or correction, email corrections@fastdol.com.
