29 CFR §1911.5

Section 6(b), when construed in light of the rulemaking provisions of the Administrative Procedure Act (5 U.S.C. 553), is read as permitting the making of minor rules or amendments in which the public is not particularly interested without the notice and public procedure which is otherwise required. Whenever such a minor rule or amendment is adopted, it shall incorporate a finding of good cause to this effect for not providing notice and public procedure.
