Regulatory Development and Retrospective Review Tracker

Rulemakings by Effect: Unfunded Mandates

The lists on this page describe whether a rulemaking is subject to Section 202 of the Unfunded Mandates Reform Act (UMRA).  If it is, the potential impacts are further categorized as affecting state, local, or tribal governments, in the aggregate, or the private sector.  Some rulemakings may have potential impacts on both the private sector and on state, local, or tribal governments. If that is the case, such rules will appear in both categories on this web page. The list includes all rulemakings in Reg DaRRT, except those that have been withdrawn or those that have been archived.
