Existing records naming the facility are read as the new name
What the document says“Any reference in a law, map, regulation, document, paper, or other record of the United States to the facility referred to in subsection (a) shall be deemed to be a reference to the "Oscar J. Upham Post Office".”
The standard conforming provision that follows a facility designation. Any federal law, map, regulation, document, paper or other record that refers to the facility is to be treated as referring to it by the new name, so that older records do not have to be reissued.
What the document actually says“Any reference in a law, map, regulation, document, paper, or other record of the United States to the facility referred to in subsection (a) shall be deemed to be a reference to the "Oscar J. Upham Post Office".”
Old papers may use the old name for this post office. Read them as if they say the new name.
Maps, laws, and forms may name this post office. Some were made before the new name. Those still count. They now mean the new name.
No action is recorded against this proposal. That is not evidence that none has been taken, and nobody has yet read it against the record. See what the tracker does not yet cover.
