SB 661 amends 39 U.S.C. §404(d) to make the Postal Service’s existing statutory requirements for closing a post office apply as well to any acceptance, processing, shipping, delivery, distribution, or other facility owned or operated by the Postal Service that supports one or more post offices. The bill accomplishes this by inserting that expanded description in five places within §404(d), so the closure, notice, and public-input obligations that currently attach to post office discontinuances will attach to those supporting facilities as well.
The change matters because it brings larger parts of the USPS operational network into the same statutory closure process that now governs post offices. That affects how the Postal Service can adjust its processing and distribution footprint, creates new notice and community-engagement obligations, and raises enforcement and implementation questions about which facilities qualify and how to balance operational flexibility with local service impacts.
At a Glance
What It Does
The bill revises the textual scope of 39 U.S.C. §404(d) by replacing references to "any post office" with an expanded list—"any post office, or any acceptance, processing, shipping, delivery, distribution, or other facility"—throughout five numbered paragraphs of that subsection. It thereby subjects those supporting facilities to the same closure and relocation procedures already codified for post offices.
Who It Affects
The change directly affects USPS-owned or -operated facilities that perform acceptance, processing, shipping, delivery, distribution, or related functions and that support at least one post office. It also affects Postal Service managers who make network decisions, local governments and community stakeholders who receive notice and can comment, and employees working at affected facilities.
Why It Matters
By folding processing and support facilities into §404(d), the bill reduces the gap between facility-level operational changes and statutory transparency requirements; network restructurings that previously could occur without the formal discontinuance process will now often trigger notice and input obligations. That shifts legal and operational risk back onto the Postal Service and gives communities stronger procedural leverage over network changes.

What This Bill Actually Does
Section 404(d) of title 39 currently sets out a specific discontinuance and relocation process for post offices: the Postal Service must provide notice, allow for public input, and take certain steps before closing or altering a post office. SB 661 does not change those procedural duties; instead, it widens which physical sites are subject to them.
Where the statute today speaks only of a "post office," the bill changes the text so it also covers acceptance points, processing centers, shipping and delivery facilities, distribution hubs, and "other" facilities owned or operated by USPS that support one or more post offices.
In practice that means actions such as consolidating a processing plant, repurposing a distribution hub, or closing an acceptance site that serves local post offices will be reviewed under the same formal framework as a post office discontinuance. The statutory framework that will attach includes the Postal Service’s obligation to publish notice, consider public comments and alternatives raised by the community, and follow the administrative steps in §404(d) before finalizing a closure decision.
The bill achieves this by making precise, textual substitutions in five numbered paragraphs of §404(d); it does not add new procedural steps or new criteria beyond folding those facilities into the existing scheme.The amendment is narrow in legal terms but broad in operational effect. It pulls into the public process parts of the USPS network that are central to mail flow.
That increases transparency for communities and employees but will require USPS to build consistent procedures for identifying which facilities "support" post offices, for notifying affected parties, and for documenting consideration of alternatives. The statutory change also raises predictable questions about leased sites, contractor-operated hubs, and facilities that support commercial partners—issues the bill does not resolve but will materialize during implementation.
The Five Things You Need to Know
The bill replaces references to "any post office" in five separate places within 39 U.S.C. §404(d) with a phrase that adds "acceptance, processing, shipping, delivery, distribution, or other facility" owned or operated by USPS that supports one or more post offices.
A facility triggers the §404(d) process only if it is "owned or operated by the Postal Service" and "supports 1 or more post offices," so stand-alone commercial facilities not operated by USPS are excluded on the face of the amendment.
SB 661 does not change the existing steps or legal standards of §404(d); it simply makes those same steps applicable to the newly included categories of facilities.
Because the amendment is textual and limited to §404(d), it leaves open how USPS will interpret "supports" (e.g.
geographic service area, mail volume, or operational dependencies) and how leased or contractor-run facilities will be treated in practice.
The bill was introduced by Senator Mike Rounds with bipartisan co-sponsors and is narrowly targeted at expanding statutory notice and public-input coverage for USPS network sites rather than overhauling operational authority or service standards.

Short title
This single-line provision names the statute the "Postal Processing Protection Act." It has no operative effect beyond providing the bill’s public label for citation.
Expand §404(d) coverage to USPS support facilities
The heart of the bill is a textual amendment to 39 U.S.C. §404(d). Rather than adding new procedures, Section 2 achieves its effect by substituting a longer phrase for references to "post office" in five places. The practical result is to make the entire §404(d) discontinuance framework capable of applying to many more categories of physical sites in the Postal Service’s network.
Apply initial §404(d) triggers to supporting facilities
Paragraph (1) of §404(d) sets the opening scope and triggers for the discontinuance process. Replacing "any post office" with the expanded list means the initial statutory trigger that brings the discontinuance machinery into play will cover acceptance, processing, shipping, delivery, distribution, and other USPS facilities that support post offices. Operationally, that turns actions affecting those facilities into "discontinuances" for purposes of notice and review rather than purely internal operational changes.
Fold supporting facilities into the decision and review language
This subsection revises the preamble to paragraph (2) and a clause in subparagraph (A)(iii), bringing supporting facilities within the specific decisionmaking and review references that paragraph (2) contains. In plain terms, where the statute instructs USPS to consider factors or provide certain documentation and opportunities for comment when a post office is affected, those same obligations will now routinely apply when a supporting facility is the subject of a proposed change.
Ensure every procedural element of §404(d) applies to support facilities
By repeating the textual substitution in paragraphs (3), (4), and (5), the bill ensures there are no residual corners in §404(d) where the discontinuance process would still be limited to post offices. That comprehensive approach minimizes statutory ambiguity about coverage, but it also means USPS must develop consistent administrative practices across multiple facility types to comply with the full set of §404(d) requirements.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Residents and local governments in communities served by processing or distribution facilities — they gain formal notice and an opportunity to comment when a supporting facility that affects local service is proposed for closure or substantial change, improving transparency and local accountability.
- Postal Service employees at affected support facilities — the extension of §404(d) raises the likelihood of advance notice, public review, and potential alternatives that could preserve jobs or allow for managed transitions rather than abrupt shutdowns.
- Local businesses and e-commerce sellers that rely on nearby processing or distribution hubs — having closures run through §404(d) gives them earlier warning and a formal record to use when seeking alternatives or advocating for mitigation measures.
Who Bears the Cost
- United States Postal Service management — the Service will face expanded procedural obligations, administrative burden, and potential delays when it seeks to consolidate or repurpose processing and distribution assets.
- Potential increase in litigation and administrative appeals — communities and unions may use the extended §404(d) mechanism to challenge closures, raising legal costs and slowing network adjustments.
- Smaller third-party or leased facility operators that partner with USPS — if a leased site is treated as "owned or operated" for §404(d) purposes, those operators could face added coordination costs and requirements to participate in public processes.
Key Issues
The Core Tension
The central tension is between preserving USPS operational flexibility to optimize a national mail network and giving local communities, employees, and businesses meaningful procedural protections when facilities that materially affect local service are changed. The bill leans toward procedural transparency; the trade-off is reduced agility for network adjustments and potential new costs and legal disputes for the Postal Service.
The bill solves a transparency gap by putting more of the USPS network under §404(d), but it leaves critical implementation questions unanswered. The statutory trigger—facilities that "support 1 or more post offices"—is conceptually clear but operationally vague: does support mean physical proximity, route dependency, regular mail flow, or contractual relationship?
Agencies implementing the change will have to create policies and possibly rulemaking or guidance to define the threshold, and those definitions will determine how disruptive the change is in practice.
Equally important, the text restricts coverage to facilities "owned or operated by the Postal Service," which sidesteps some complications (e.g., purely commercial carriers or third-party hubs) but raises thorny questions about leased properties and contractor-operated sites. The bill also does not create a new enforcement mechanism, dedicated funding, or timelines for notice and review; it relies on the existing §404(d) framework and existing oversight channels, which could produce uneven compliance and litigation-driven interpretations.
Finally, expanding procedural requirements increases the risk USPS will defer necessary operational consolidations or absorb higher operating costs, shifting fiscal pressure elsewhere in the system.
