What EPA Actions Appear on the AILs? Generally, AILs include those actions that 1) will appear in upcoming Semiannual Regulatory Agenda and 2) have been approve

EPA's Regulatory Policy Officer. In rare instances, an action will not appear on an AIL before it appears in the Agenda. Also, ke

post immediately. You can access a given month's list roughly 15 days after the close of the month (e.g., the April 2008 AIL will 15th). 

What Does Each Column in the AIL Mean? RIN RIN stands for "Regulation Identifier Number." A RIN is assigned by the Regulatory Information Service Center, a component of 

Administration, to identify each regulatory action listed in our Semiannual Regulatory Agenda and Annual Regulatory Plans. Als

headings of our rules when they are published in the Federal Register to make it easier for you to track our actions. An example 

AG37. It is composed of two parts. The first part (i.e., 2050) identifies which office within EPA is in charge of the action. In this cWaste and Emergency Response. The second part (e.g., AG37) is an alpha-numeric code automatically generated as rules are

Additionally, if a rule is in EPA's R(www.epa.gov/rulemaking/), then a link to the rule's profile will be provided in this column. Abstract A brief summary of the action and its purpose. Projected Publication Date Since many variables affect how long it takes to write a rule or other action, it is difficult to predict a firm publication date when won an action. Therefore, we insert one of two options in the "Projected Publication Date" column: 1) "12 months or less" and 2) 

These options give you some idea of how quickly we expect to complete an action.
