Part SUBCHAPTER-B — Appendices to Subchapter B of Chapter III
Between Sept. 30, 1998 and today (current through Oct. 22, 2026): 0 amended, 2 added, 3 removed, 0 unchanged.
Sept. 30, 1998 falls before day-level history begins (Jan. 1, 2017). It is read from the annual CFR edition in force that day (revised as of October 1), so an amendment that took effect earlier in that edition year is counted as already in place. Federal Register citations on each section give exact effective dates.
