Key takeaways
- Secretary's Order No. 3451, effective 10 July 2026, combines all functions, personnel, assets, authorities and responsibilities of BOEM and BSEE into a single bureau, the Marine Minerals Administration (MMA).
- Every existing regulation and standard stays in force. 30 CFR Part 250 Subpart Q, the Idle Iron clock and the financial assurance rules are unchanged by the Order itself.
- MMA documents are already in circulation. A Gulf accident investigation report printed in September 2026 carries MMA letterhead and tells readers that MMA staff are identified in the report as BSEE personnel.
- For suppliers the practical change is organisational, not legal: one Director, one delegation chain and a nine-month deadline to finalise regional and programme alignment.
The agency that approves your client’s decommissioning application has a new name.
On 10 July 2026 the Department of the Interior issued Secretary’s Order No. 3451, titled Establishment of the Marine Minerals Administration. The Order reunifies the Bureau of Ocean Energy Management and the Bureau of Safety and Environmental Enforcement into one bureau: the Marine Minerals Administration, or MMA.
Nothing in the Order changes a plugging requirement, a removal deadline or a bonding threshold. That is the first thing to understand, and the thing most easily lost in the headline.
What the Order actually does
Section 4 is the operative text. It establishes MMA, makes it responsible for “all aspects of the Department’s offshore energy and mineral resource management and conservation, safety oversight, environmental enforcement and related activities on the OCS,” and places it under a Director who reports to the Assistant Secretary — Land and Minerals Management.
Section 4(b) then combines and vests in MMA all functions, personnel, assets, obligations, authorities and responsibilities of both predecessor bureaus. The same subsection states that all existing regulations and standards applicable to BOEM and BSEE remain in full force and effect under MMA authority.
The Order is issued under sections 2 and 5 of Reorganization Plan No. 3 of 1950 and the Outer Continental Shelf Lands Act. It revokes Secretary’s Order No. 3302 outright and supersedes the inconsistent parts of Secretary’s Order No. 3299 — the 2010 order that split the former Minerals Management Service apart after Deepwater Horizon.
The Office of Natural Resources Revenue is deliberately left alone. Section 4(c) keeps ONRR’s functions under the Assistant Secretary — Policy, Management and Budget, and Section 3 explains why: revenue collection was the conflict of interest that the 2010 split was designed to cure, and the Department is not reversing that part.
The Order is a management reorganisation, not a deregulation. Read it as a change in who signs, not in what is required.
The case the Department makes
Section 3 of the Order sets out the Department’s own numbers, and they are worth keeping because they are a rare published snapshot of the oversight workload:
| Measure | Figure in the Order |
|---|---|
| Outer Continental Shelf acreage | 3,167,568,771 acres |
| Active OCS leases (as of December 2025) | nearly 2,000 |
| Offshore structures under oversight | nearly 1,300 |
| Inspections performed annually | more than 12,000 |
| 2025 inspections of oil and gas structures | approximately 11,980 |
| 2025 inspections of offshore wind facilities | approximately 20 |
The Department argues that two bureau structures created duplicative executive leadership, administrative operations, IT systems and support functions across organisations with a common mission and an overlapping workforce. It notes that regional operations were already co-located in New Orleans, Camarillo and Anchorage, and headquarters functions in Sterling and Washington.
Section 3 also addresses the obvious objection directly. It states that reviews of Deepwater Horizon concluded the root causes primarily involved operational failures by companies and operators rather than organisational deficiencies within the former MMS, and that the post-2010 reforms — enhanced well control requirements, mandatory SEMS, strengthened blowout preventer standards, expanded inspection capacity and third-party verification — remain in the Department’s regulations.
That is a contestable reading of the record, and it is being contested. Suppliers do not need to settle the argument. They need to know who holds the pen.

A denominator warning
The “nearly 1,300 offshore structures” figure will tempt comparison with the counts we publish. Resist it.
That number is a Department-wide count of structures under oversight across all OCS regions. The 806 standing structures in our platform-removal scope analysis is a Gulf count filtered to structures inside tracked campaigns that are not marked completed. The 1,304 segments in our pipeline analysis counts a different asset class entirely.
Three sources, three denominators, three legitimate numbers. A brief that mixes them is wrong even when every figure in it is quoted correctly. This is the same discipline we described in building a useful public data product: state the filter, or the number is decoration.
The transition is already visible in the record
Section 5 directs the Department to operationalise MMA in phases, and authorises BOEM and BSEE Directors and staff to retain any operational authority needed for uninterrupted work until the MMA Director notifies them otherwise. In practice that means the transition surfaces document by document.
It has started. A Gulf accident investigation report printed on 25 September 2026 — Form 2010 for an incident at South Pass 28 — is headed “UNITED STATES DEPARTMENT OF THE INTERIOR / MARINE MINERALS ADMINISTRATION / GULF OF AMERICA REGION.” The narrative then adds a note that at the time of the investigation MMA personnel were operating under the former BSEE, and that all MMA personnel referenced in the report are therefore identified as BSEE personnel.
A research final report published the same month carries the same change: Bridging the Gap Between the Dispersion Effectiveness at Various Scales, dated August 2026, is issued by the “US Department of the Interior, Marine Minerals Administration, Oil Spill Preparedness Division,” under a contract that was awarded when the funding bureau was BSEE.
Two small artefacts, one useful lesson: documents from this period will mix old and new agency identity, sometimes in the same paragraph. Anyone building a filing-based evidence trail should expect both strings.
What changes for a service company
Little, immediately. A great deal, over the next year.
Unchanged. The decommissioning obligations in 30 CFR Part 250 Subpart Q. The Idle Iron clock. Removal and site clearance deadlines. The application-to-clearance sequence. Financial assurance regulations. Permit forms and their content. None of these is touched by the Order.
Changed or changing. Section 7 delegates to the MMA Director all authority necessary for the offshore mission, including any existing or future authority applicable to BOEM or BSEE, and supersedes conflicting delegations. Section 6(b) gives the MMA Director nine months from the effective date to finalise the organisational structure and deployment, including programme and regional office alignment and the distribution of inspection, enforcement, leasing and permitting personnel. The same subsection directs the Director to expand and modernise the offshore safety and inspection programme, and to report to the Secretary within one year on what was implemented.
Nine months from 10 July 2026 lands in April 2027. One year lands in July 2027. Those are the dates to diarise.
Worth watching. Leasing and enforcement used to sit in different bureaus with different incentives. Putting both under one Director changes the internal path a decommissioning dispute travels. It may speed an approval. It may also mean that an operator’s leasing relationship and its compliance record are reviewed by the same chain of command — which is precisely the coordination the Order advertises.
Practical steps for the next quarter
- Fix your source citations. If your qualification pack or brief template cites “BSEE” as the issuing authority, add MMA. Do not delete BSEE: historical filings, forms and the data portal still carry it.
- Keep both strings in any search. Scrapers, alerts and keyword monitors tuned only to “BSEE” will miss MMA-headed publications from September 2026 onward.
- Do not re-interpret a regulation. If a colleague tells you a requirement changed because the agency changed, ask for the Federal Register citation. The Order supplies none, because it changes none.
- Expect contact churn. Personnel realignment is explicitly in scope under Section 6(a) and 6(b). District and regional contacts may move. Relationships built on a single named inspector are fragile this year.
- Separate the reorganisation from the rulemaking. Interior is simultaneously running substantive proposals on financial assurance. Those change obligations. This Order does not. Treat them as two files.
Where the real risk sits
Section 9 states that the Order is intended to improve internal management and creates no enforceable right or benefit, and that where it conflicts with federal law or regulation, the law or regulation controls.
That is standard language, and it is also the practical answer to the question suppliers keep asking. Your client’s removal deadline did not move because a bureau was renamed. The obligation sits in the regulation, and the regulation survived the reorganisation intact.
The commercial risk in a transition year is not legal. It is informational: stale agency names in your evidence trail, missed publications, contact lists that quietly go out of date, and the temptation to read a management order as a signal about enforcement appetite. The published record is the only safe guide, and it is now published under two names.
That is exactly the kind of sourcing problem a one-off Opportunity Brief is built to absorb — the filing, the authority that issued it, the date, and what it does and does not establish.
