OSHA State Plan — coverage and jurisdiction
South Carolina operates an OSHA-approved State Plan covering all private-sector employers and employees (with exceptions noted below) and all state and local government employers and employees. The state received initial approval on December 6, 1972, and final approval on December 18, 1987. Federal OSHA retains jurisdiction over maritime employment (shipyard employment, marine terminals, longshoring), contract workers and contractor-operated facilities engaged in United States Postal Service mail operations, private-sector employment at Area D of the Savannah River Site and at Three Rivers Solid Waste Authority, employment on military bases, federal government workers, and working conditions of aircraft cabin crewmembers onboard aircraft in operation.
Adoption of federal OSHA standards — identical incorporation
South Carolina has identically adopted federal OSHA standards and regulations applicable to private-sector and state and local government employment. The Director of the South Carolina Department of Labor, Licensing and Regulation has statutory authority to promulgate, modify, or revoke occupational safety and health regulations "for the purpose of attaining the highest degree of health and safety protection for any and all employees working within the State of South Carolina, whether employed in the public or private sector" under S.C. Code § 41-15-210.
Incorporation by reference. SC OSHA implements this authority through the South Carolina Code of Regulations Chapter 71, Article 1, which incorporates federal OSHA standards by reference. S.C. Code of Regs. § 71-108 provides that "[t]he standards of agencies of the U.S. Government which are legally incorporated by reference in this article, have the same force and effect as other standards in this article." Federal standards applicable to general industry (29 C.F.R. Part 1910), construction (29 C.F.R. Part 1926), maritime (29 C.F.R. Part 1915), and agriculture (29 C.F.R. Part 1928) are incorporated into South Carolina regulations and serve as the minimum standards for workplace safety and health. Changes to the incorporated federal standards "are available for inspection at the South Carolina Department of Labor" per § 71-108(C).
Identical adoption — no substantive state variations. The official federal OSHA South Carolina State Plan page states unequivocally: "SC OSHA has identically adopted OSHA standards and regulations applicable to private sector and state and local government employment." When federal OSHA amends its standards, South Carolina promulgates corresponding amendments to keep its regulations in alignment. Under S.C. Code § 41-15-220(B), notice published in the State Register after promulgation "must refer to the federal occupational safety and health administration standards which have been repromulgated under this section and give specific notice of differences between the state and federal standard."
Unique state standards. The OSHA State Plan page notes that "SC OSHA has adopted the following unique standards" but does not enumerate them on that page. A review of Chapter 71 amendments published in the State Register between 1993 and 2020 shows South Carolina has occasionally adopted federal standards on different effective dates or with minor procedural variations (for instance, amendments to mechanical power press inspection-certification requirements in 2014), but the substantive safety requirements remain identical to the corresponding federal standards. Practitioners should consult the South Carolina Department of Labor OSHA Standards Office or the official SC OSHA standards list at https://osha.llr.sc.gov for current unique or modified standards, if any.
Practical effect for employers. Because South Carolina has identically adopted federal OSHA standards, employers may rely on federal OSHA interpretive guidance (compliance directives, standard interpretations, fact sheets) and federal OSHA training materials when determining compliance obligations under South Carolina law. The substantive requirements for hazard communication (1910.1200), lockout/tagout (1910.147), respiratory protection (1910.134), fall protection (1926.501), and all other federal standards apply without modification in South Carolina workplaces covered by the State Plan. Enforcement is conducted by SC OSHA compliance officers under state law, and contested citations are reviewed by the South Carolina Administrative Law Court under S.C. Code § 41-15-310 (not the federal Occupational Safety and Health Review Commission).
Regulatory update procedure. Occupational safety and health standards promulgated under Chapter 71 are not subject to the South Carolina Administrative Procedures Act (S.C. Code § 41-15-220(B)). Before promulgating, modifying, or revoking a regulation, the Director must conduct a public hearing at which interested persons may present comments. Notice of the hearing must be published in the State Register and in at least three newspapers (one each with circulation in upper, lower, and middle South Carolina) once a week for three weeks, and must contain the date, time, and place of the hearing and a brief description of the proposed regulation.
