Federal Register Although the CFR is revised only once a year, new regulations and changes to existing regulations may be issued and take effect at any time. Changes, and proposed changes, to Federal regulations are published daily in the Federal Register. The Federal Register publishes a monthly list of CFR sections affected by new regulations (called the LSA). Also, every Federal Register contains a list of all CFR sections affected so far that month. Our citations of the CFR give the volume number followed by the page number; for example, 67 FR 79836-79837 refers to a document published on pages 79836 and 79837 of volume 67 of the Federal Register. The Federal Register follows sequential page numbering within volumes.
