Distribution of Administrator-Signed Rules

Statistics on Administrator-Signed rules by EPA program office, Region, and year

Tables and Charts


Much of the Agency's work is devoted to the development of highly technical and complex rules known as "Administrator-Signed rules." Many of these complex rules are in fact signed by the EPA Administrator. The Agency publishes roughly 80-150 Administrator-Signed rules each calendar year. For the period 2005-2010, nearly three-fourths of all Administrator-Signed rules were developed by the Office of Air and Radiation (OAR). The Office of Solid Waste and Emergency Response (OSWER) and the Office of Water (OW) each individually accounted for approximately nine and seven percent of the Administrator-Signed rules, respectively. The remaining program offices and Regions together accounted for the remaining 10 percent. (The remaining offices are the Office of Environmental Information (OEI); Office of Chemical Safety and Pollution Prevention (OCSPP); Office of Enforcement and Compliance Assurance (OECA); Office of Research and Development (ORD); Office of the Administrator (OA); Office of Policy (OP); and EPA Regions. EPA Regions do not account for many of the Administrator-Signed rules, so for purposes of this analysis they are treated as one office.)

From 2005-2010, EPA published 735 Administrator-Signed rules, most of which were proposed (44%) or final rules (43%).

Five offices (OAR, OCSPP, OEI, OSWER and OW) published Administrator-Signed rules consistently across all six calendar years in this analysis, and accounted for 96-98 percent of all the Administrator-Signed rules each year. There were two offices that only published Administrator-Signed rules in four of the six years of this analysis (OECA and EPA Regions), no offices that published rules in three of the six years, and three offices (OA, OP, and ORD) with Administrator-Signed rules only in two calendar years or less. The offices that did not publish Administrator-Signed rules across all five years are grouped together and represented as 'Other' in the charts. However, the data tables show the distribution of Administrator-Signed rules for these offices across the relevant years.

Looking more closely at the regulatory development process of each Administrator-Signed rule, for the period 2005-2010, an average of twenty-one percent were developed on a fast-track basis (i.e., both proposed and finalized in the same calendar year). Most of the fast-track rules were developed by OAR.
