The NOP page is not archived because the purpose of the NOP is to inform the public of the availability of a CEQA document for public review.  When the review period has ended and the document has been approved or incorporated into a subsequent document, the notice has served its notification purpose and is no longer necessary; thus, the NOP need not be archived.
