Withdrawn Rulemakings
Sometimes, EPA will choose to terminate a rulemaking. The Withdrawn page lists those rulemakings that have bee withdrawn in the past year.


This site provides summaries of priority rulemakings and priority retrospective reviews of existing regulations. We update most of the site at the beginning of each month, though some data is updated more frequently if it is time sensitive. The information on this site is not intended to and does not commit EPA to specific conclusions or actions. For example, after further analysis, EPA may decide the effects of a rule would be different or it may decide to terminate a rulemaking.
