SUPPLEMENTARY INFORMATION:

I. Background

    Section 18 of the Occupational Safety and Health Act of 1970 (the 
OSH Act), 29 U.S.C. 667, provides that States that wish to assume 
responsibility for developing and enforcing their own occupational 
safety and health standards may do so by submitting and

[[Page 21964]]

obtaining federal approval of a State Plan. State Plan approval occurs 
in stages that include initial approval under Section 18(c) of the Act 
and, ultimately, final approval under Section 18(e). In the interim, 
between initial approval and final approval, there is a period of 
concurrent federal/state jurisdiction within a state operating an 
approved plan.
    Puerto Rico administers an OSHA-approved State Plan to develop and 
enforce occupational safety and health standards for public-sector and 
private-sector employers, pursuant to the provisions of Section 18 of 
the OSH Act. The Puerto Rico Occupational Safety and Health 
Administration (PR OSHA) was designated as the state agency responsible 
for administering the State Plan. PR OSHA is part of the Puerto Rico 
Department of Labor and Human Resources which is headed by Maria del 
Pilar V[eacute]lez Casanova. The Puerto Rico State Plan received 
initial federal OSHA approval as a developmental State Plan under 
Section 18(c) of the OSH Act on August 15, 1977 (42 FR 43628). 
Subsequently, on September 7, 1982, federal OSHA issued a Certification 
of Completion of Developmental Steps for the Puerto Rico State Plan (47 
FR 39164).
    Pursuant to Section 18(e) of the OSH Act, as implemented by 29 CFR 
1954.3, OSHA and Puerto Rico entered into an initial OSA dated December 
8, 1981 (47 FR 25323), whereby concurrent federal enforcement authority 
was suspended with regard to federal occupational safety and health 
standards in issues covered by the State Plan.

II. Notification of New Operational Status Agreement

    On September 25, 2025, OSHA and the Puerto Rico Department of Labor 
and Human Resources signed a new OSA, replacing the previous one. The 
new OSA makes several changes to the respective coverage between 
federal OSHA and PR OSHA, as described below.
    The revisions to the OSA were initially precipitated when, on April 
4, 2025, Puerto Rico's Assistant Secretary of Labor, Nelvin Rodriguez-
Sanchez, sent a letter to OSHA to state PR OSHA's belief that it lacks 
the occupational safety and health resources to provide coverage for 
private sector employees performing work in the following 
circumstances: on land, property, or space that the federal government 
owns or leases where federal employees are regularly present for the 
purpose of performing their official duties; at federal government-
owned contractor-operated sites; on federal property under 
construction; and marine construction performed by private sector 
employees. Under the existing OSA, federal OSHA only had coverage of 
enforcement related to contractors or sub-contractors on federal 
establishments when the State Plan could not obtain entry, and federal 
OSHA did not have coverage over marine construction conducted by 
private sector employers. In PR OSHA's letter, the State Plan requested 
a change in coverage and sought confirmation that federal OSHA will 
always provide coverage over private sector employees in both of these 
circumstances. After discussions between federal OSHA and the Puerto 
Rico State Plan on this issue, both agencies agreed that federal OSHA 
coverage of such private-sector employers on property owned or leased 
by the federal government in Puerto Rico and marine construction 
conducted by private sector employees was the best solution to ensure 
prompt and effective protection of these workers. Accordingly, notice 
is hereby given of this change in federal enforcement authority, and 
coverage is transferred from the Puerto Rico State Plan to federal 
OSHA. This change is memorialized in the 2025 OSA, which now states 
that federal OSHA has enforcement authority in these circumstances.
    While reviewing the existing OSA in response to this coverage 
change request from the Puerto Rico State Plan, it was determined that 
several other revisions and clarifications to the OSA were also needed. 
First, it has long been the case that federal OSHA exercises 
enforcement authority over private sector employers within the secured 
borders of all U.S. military installations where access is controlled, 
and PR OSHA has enforcement authority over state and local government 
employers on such military installations. However, this division of 
coverage was not previously specified in the 1981 OSA. Accordingly, 
that provision was added to the 2025 OSA for thoroughness and clarity.
    Second, the existing 1981 OSA did not have provisions reflecting 
coverage changes that occurred after it became effective, including 
that federal OSHA covers federal government employers, including the 
United States Postal Service (USPS), as well as contractors and 
contractor-operated facilities engaged in USPS mail operations, and 
that federal OSHA covers all working conditions of aircraft cabin 
crewmembers onboard aircraft in operation. Accordingly, provisions 
identifying both of those as subject to federal OSHA coverage were also 
added to the 2025 OSA.
    Third, the 1981 OSA contained several sections discussing aspects 
of the Puerto Rico State Plan un-related to the respective coverage 
between federal OSHA and PR OSHA, including, for example, OSHA's 
determination that the Puerto Rico State Plan had achieved operational 
status and various commitments that the State Plan made to continue as 
an operational State Plan moving forward. OSHA no longer includes this 
kind of information in more modern OSAs and instead focuses the content 
of the OSA on its stated purpose, i.e., to set forth the scope of the 
exercise of federal authority by delineating areas of state versus 
federal responsibility. Accordingly, the 2025 OSA no longer contains 
sections discussing those aspects of the Puerto Rico State Plan that do 
not relate to the scope of federal coverage. However, the removal of 
those sections from the 2025 OSA does not change any of federal OSHA's 
determinations on the State Plan's operational status, nor the State 
Plan's ongoing obligations.
    Fourth, the 1981 OSA had a provision noting that federal OSHA would 
retain coverage over any open cases remaining from federal inspections 
conducted prior to the ``operational status'' of the Puerto Rico State 
Plan. Because PR OSHA has now been operational for over forty years, 
there are no longer any open federal cases falling within this 
provision, therefore it was determined this provision was no longer 
necessary and it has been deleted from the 2025 OSA.
    Fifth, the 1981 OSA had a provision noting that federal OSHA could 
exercise its authority to enforce new standards until such time as the 
State Plan adopted a comparable standard and a provision noting that 
Federal OSHA could exercise its authority to enforce new standards that 
are particularly unique or complex. As is common in more modern OSAs, 
these specific provisions have been removed and replaced with a more 
general provision noting that federal OSHA can inspect and take 
appropriate enforcement action in extraordinary circumstances or when 
the State Plan is not able to fully or effectively exercise its 
enforcement authority, which could include both situations, among 
others.
    Sixth, the 2025 OSA includes a new provision that notes that 
federal OSHA can exercise its authority to inspect and take appropriate 
enforcement action at an entire project or facility where federal and 
State Plan authorities both have enforcement authority in the interest 
of administrative practicability.

[[Page 21965]]

The provision states that federal enforcement may be exercised 
immediately upon agreement between federal OSHA and the State Plan. 
This provision was not included in the 1981 OSA but is a standard 
provision federal OSHA has found helpful with experience over the past 
several decades to include in more modern OSAs. Accordingly, it has 
been added to the 2025 OSA.
    Finally, the 1981 OSA contained a provision noting that OSHA would 
publish a notice in the Federal Register to describe instances of 
resumed federal enforcement authority. This provision has been removed 
from the 2025 OSA, as it is redundant of existing notice obligations 
OSHA has codified in State Plan-related regulations. Accordingly, it is 
no longer necessary to include this provision in the OSA.
    Effective immediately, federal OSHA and PR OSHA will exercise their 
respective enforcement authorities according to the terms of the 2025 
OSA between them. As detailed in the 2025 OSA, federal enforcement 
responsibility under the OSH Act will continue to be exercised with 
regard to: federal government employers, including the United States 
Postal Service (USPS), as well as contractors and contractor-operated 
facilities engaged in USPS mail operations; private sector employers 
within the secured borders of all United States military installations 
where access is controlled; all working conditions of aircraft cabin 
crewmembers onboard aircraft in operation; private sector employers 
performing work on federal government owned or leased property where 
federal employees are regularly present, at federal government-owned 
contractor-operated sites, and construction on federal property; marine 
construction conducted by private employers; all maritime employment, 
including shipyard employment, marine terminals, and longshoring; 
situations where PR OSHA is refused entry and is unable to obtain a 
warrant or enforce the right of entry; and situations where PR OSHA is 
temporarily unable to exercise its enforcement authority fully or 
effectively. Federal responsibility will also continue to be exercised 
with regard to investigation and inspection for the purpose of carrying 
out the monitoring obligations under Section 18(f) of the OSH Act, 29 
U.S.C. 667(f), as implemented by 29 CFR part 1954, and the enforcement 
of complaints filed with federal OSHA under the OSH Act's whistleblower 
provision, Section 11(c), 29 U.S.C. 660(c). The exceptions to the 
Puerto Rico State Plan's occupational safety and health coverage are 
listed on OSHA's website at https://www.osha.gov/stateplans/pr.
