The public often wants to know how long it takes EPA to develop a rule from beginning to end. Therefore, the data found in this section of the website shows the average amount of time it takes to develop Administrator-Signed rule from the point the rule is initiated and a workgroup commences any type of activity on that rule to the point that the rule is finalized, signed by the Administrator and published in the Federal Register. The development time is broken down into three categories: from initiation to proposed rule stage (Initiation – NPRM), proposed rule to publication of the final rule stage (NPRM – Final) and the overall development time of initiation to publication of final rule stage (Initiation – Final). The average development time for the Administrator-Signed rules is also presented across program offices for each of the five calendar years.
The development time (i.e., time from initiation or commencement of a rulemaking to final rule stage) for publication of a Administrator-Signed rule varied between roughly two to three years (625-1,084 days) for the period 2005-2010, with a total average development time of two years and six months (930 days).
There was some variation in the development time across the five main offices with published Administrator-Signed rules, with the Office of Air and Radiation (OAR), Office of Environmental Information (OEI), and Office of Water (OW) posting the shortest average durations for the period 2005-2010.
Average durations were greater than the median duration, suggesting the presence of outliers. Each office has its characteristic set of rules and it is important to note that the development time can be greatly influenced by a variety of internal and external factors. These factors include the complexity of the rulemaking, whether the rulemaking is under a court-schedule or legislative mandate, the interests of other program offices, and the extent of public involvement during the rule development process, as well as other factors. In that regard, the average and median development time was largely similar across years for each office.
