A new Operational Status Agreement between federal OSHA and the Puerto Rico State Plan has quietly reshuffled enforcement jurisdiction in ways that matter a great deal if you employ workers on federal properties in Puerto Rico or do any marine construction work there. This isn't a minor administrative update — it's a real shift in who shows up to inspect your site and under whose authority.
Here's what changed, why it matters, and what you should actually do about it.
What Is a State Plan, and Why Does the OSA Matter?
Before getting into the specifics, a little context. Under Section 18 of the Occupational Safety and Health Act of 1970, states (and territories) can develop and operate their own OSHA programs, called State Plans, if they adopt standards that are "at least as effective" as federal OSHA's. Puerto Rico has operated a State Plan since 1977, which means the Puerto Rico Department of Labor and Human Resources — not federal OSHA — has historically been the enforcement authority for most private-sector employment on the island.
An Operational Status Agreement (OSA) is the formal document that spells out exactly where federal authority ends and State Plan authority begins. When that boundary shifts, the OSA has to be updated to reflect it. The Federal Register notice published April 24, 2026 (Docket No. OSHA-2025-0012, Document 2026-08108) does exactly that — it announces a new OSA and formalizes a specific change to the allocation of enforcement responsibility.
What Actually Changed: Federal OSHA Is Back in Two Specific Areas
The core of this update is a reinstatement of federal OSHA enforcement authority over two categories of private-sector work that had previously been covered by the Puerto Rico State Plan:
- Private-sector employment on federal properties in Puerto Rico
- Marine construction conducted by private-sector employees in Puerto Rico
In plain terms: if your workers are private-sector employees doing work on a federal installation — think military bases, federal office buildings, federal land — or if you're running a marine construction operation in Puerto Rican waters, federal OSHA is now your compliance authority, not the Puerto Rico State Plan.
This is a reversion, not a new rule. Federal OSHA is reclaiming jurisdiction it originally held before an earlier OSA extended those responsibilities to Puerto Rico. The current change reinstates the original allocation.
Why This Matters More Than It Sounds
Jurisdiction might feel like a bureaucratic question, but it has real operational consequences for employers. Here are a few worth thinking through.
The standards that apply may differ. Puerto Rico's State Plan is required to be at least as effective as federal OSHA, but it can go further. In areas where Puerto Rico has adopted stricter or differently structured standards, federal OSHA's standards now govern the affected worksites — not Puerto Rico's. If your safety program was built around the Puerto Rico State Plan's specific requirements, you may have gaps under federal OSHA.
The inspection process is different. Federal OSHA inspections, citations, and appeals follow federal procedures under 29 CFR Part 1903 and 29 CFR Part 1904, including federal timelines, penalty structures, and contest procedures. Puerto Rico has its own parallel administrative framework. If you're used to operating under the State Plan's process, the federal process will feel different — and some of the deadlines are unforgiving.
Recordkeeping requirements follow jurisdiction. Federal OSHA's injury and illness recording requirements (29 CFR Part 1904) apply to federal OSHA-covered establishments. If your Puerto Rico operation on a federal property had been maintaining records under the State Plan's framework, that needs to be reviewed against Part 1904 directly.
In my view, the employers most at risk of being caught flat-footed here are contractors who work primarily across Puerto Rico's private sector but have some federal property contracts — maybe one federal construction project or a recurring service contract on a federal installation. They haven't needed to track federal OSHA's jurisdiction separately, and now they do.
The Regulatory Basis: Where to Find the Authority
This change is grounded in Section 18(e) of the OSH Act, which governs the conditions under which a State Plan is approved and the circumstances under which federal authority may be retained or reclaimed. The Federal Register document (29 CFR Part 1952) memorializes the revised OSA and gives official notice of OSHA's approval.
The notice was published in the Federal Register on April 24, 2026. Employers with operations in the affected categories should treat that date as the relevant reference point for when the jurisdiction change became operative, though you should confirm the specific effective date language in the Federal Register document itself, as implementation timelines occasionally differ from publication dates.
A Practical Look at Who Is Affected
Not every employer in Puerto Rico is touched by this. Here's a quick breakdown.
| Employer Type | Previous Authority | Authority Under New OSA |
|---|---|---|
| Private-sector employer, non-federal property | Puerto Rico State Plan | Puerto Rico State Plan (no change) |
| Private-sector employer on federal property | Puerto Rico State Plan | Federal OSHA |
| Marine construction, private-sector employees | Puerto Rico State Plan | Federal OSHA |
| Federal government employees | Federal OSHA (always) | Federal OSHA (no change) |
| State/territorial government employees | Puerto Rico State Plan | Puerto Rico State Plan (no change) |
The vast majority of Puerto Rico's private-sector workforce sees no change. The shift is targeted — but for the employers it touches, it's meaningful.
What You Should Do Now
If you have operations in Puerto Rico, here's how I'd approach this.
Step one: Audit your footprint. Identify every worksite in Puerto Rico and determine whether any are located on federal property. Federal installations, federally owned or leased office buildings, military facilities, national parks, and similar sites all qualify. If you do marine construction of any kind, flag that work immediately.
Step two: Compare your safety program against federal OSHA standards. You don't need to rebuild from scratch — Puerto Rico's standards are largely aligned with federal OSHA — but you should run a gap analysis against the specific federal standards that apply to your work. Pay particular attention to any areas where Puerto Rico had diverged from federal standards, even modestly.
Step three: Update your recordkeeping practices. If you have an OSHA 300 log maintained under the Puerto Rico State Plan's framework for an affected worksite, review it against 29 CFR Part 1904 to confirm you're meeting federal requirements. The injury and illness recordkeeping standards are similar but not identical in every detail.
Step four: Know your contacts. Federal OSHA's region covering Puerto Rico is Region II (New York). Their area office handles federal OSHA complaints, inspections, and enforcement matters for Puerto Rico. If you've been dealing exclusively with Puerto Rico State Plan contacts, add the federal area office to your compliance contacts now.
Step five: Brief your site supervisors. The people running your day-to-day operations need to understand this change. If a federal OSHA inspector shows up on a federal property job site and your supervisor doesn't know what authority that inspector is operating under, that's a problem you don't need.
The Bigger Picture: State Plans and Federal Oversight
Puerto Rico's State Plan has a complicated history worth understanding. In 2015, federal OSHA placed the Puerto Rico State Plan in "concurrent federal enforcement" status — meaning federal OSHA could enforce directly alongside the State Plan — following concerns about the State Plan's performance. That concurrent status was significant because it meant employers in Puerto Rico could face federal OSHA inspections and citations even for work that nominally fell under State Plan jurisdiction.
The 2026 OSA update is part of an ongoing process of clarifying and reallocating responsibilities as the State Plan's performance and status has evolved. The reinstatement of federal authority specifically over federal properties and marine construction is a narrowing of State Plan jurisdiction in those targeted areas, not a return to full concurrent enforcement across the board.
According to OSHA data, there are 29 OSHA-approved State Plans covering 22 states and 7 territories and jurisdictions, including Puerto Rico. Each State Plan covers a defined scope of employment, and the OSA is what defines that scope precisely. Changes to the OSA happen relatively rarely, which is part of why this one deserves attention.
Employers operating across multiple jurisdictions under State Plans should understand that each OSA is distinct — what applies in Puerto Rico does not necessarily apply in California or Washington, even though all three are State Plan jurisdictions.
One More Thing Worth Naming
I've worked with clients who assume that because a territory has a State Plan, federal OSHA is essentially out of the picture. That assumption is always a little dangerous, and this update is a concrete reminder of why. Federal OSHA never fully exits a State Plan jurisdiction — it retains concurrent authority under certain conditions and can reclaim enforcement responsibility when the facts warrant it. The boundary is real, but it moves.
If your compliance program treats Puerto Rico as a single uniform jurisdiction without accounting for the type of property your workers are on, now is a good time to revisit that.
