Significant regulatory action is a term used to describe an agency rule that has had or might have a large impact on the economy, environment, public health, or state or local governments.

Executive Order 12866, issued by President Bill Clinton (D) in 1993, directed the Office of Management and Budget (OMB) to determine which agency rules qualify as significant rules and thus are subject to OMB review.
Significant rules have had or might have a large impact on the economy, environment, public health, or state or local governments. These actions may also conflict with other rules or presidential priorities. Executive Order 12866 further defined an economically significant rule as a significant rule with an associated economic impact of $100 million or more. Executive Order 14094, issued by President Joe Biden (D) on April 6, 2023, made changes to Executive Order 12866, including referring to economically significant rules as section 3(f)(1) significant rules and raising the monetary threshold for economic significance to $200 million or more.[2]
The text of the rule states that OMB deemed this rule a section 3(f)1 rule under E.O. 14094:
| “ | This action is a 'significant regulatory action,' as defined under section 3(f)(1) of Executive Order 12866, as amended by Executive Order 14094.[5] | ” |
