About This Site

The primary focus of this website is to provide basic data and statistics on the more prominent rules issued by the EPA Administrator during the period 2005-2010.

EPA protects public health and the environment in a variety of ways, but one of the most important ways is through the development of regulations. EPA regulations cover a range of environmental and public health protection issues, from setting standards for clean water and establishing requirements for proper handling and reductions of toxic wastes to controlling air pollution from industry and other sources. Each year, the Agency develops a considerable number of rules which address highly technical, scientific, and complex environmental problems.

EPA publishes roughly 2,000 documents in the Federal Register (FR) each year. Of the documents published each year, the majority are Notices. The Office of Policy (OP) has identified a subset of these as "Administrator-Signed Rules". EPA's Administrator-Signed rules are only those published actions which are signed by the Administrator and which modify or propose to modify the Code of Federal Regulations (CFR) and therefore, contain rule text. The data compiled and presented on this site primarily draws on this subset of rules signed by the EPA Administrator.

Overview of Data

OP tracks and guides the rule development process within the Agency. OP monitors the development of regulations through the various regulatory stages, from the initial commencement of the rulemaking process to the final publication of the action. This site provides summary statistics on all FR publications for each calendar year (2005-2010) by EPA program offices and Regions. To learn more about the general process used to develop rules and the typical regulatory stages of development, please visit Reginfo.gov, which provides a chart called "Reg Map" that gives an overview of the rulemaking process.

Source Data

The statistics presented on this website are the result of original research conducted by OP. Data was collected from internal EPA databases. You may download the source data by choosing from the lists below. The source data includes dates that documents were published in the FR. If you wish to locate a particular document listed in the source data, you may do so by visiting the Federal Register website maintained by the U.S. Government Printing Office. If you have questions about the data or statistics, please contact us.

You can download an Excel file or universal spreadsheet file to compute the statistics for this site. The files below are offered in both Excel and the CSV file format. CSV is a common format for storing tabular data and should be accessible to most users.

Definitions

For the purposes of this website, these terms have the following meanings. These terms may have other meanings in other regulatory contexts.

  • Action – An action is an activity EPA undertakes to implement its mission. Agency action can include rules, policy statements, risk assessments, guidance documents, models that may be used in future rulemakings, Reports to Congress that are statutorily mandated, and strategies that are related to regulations. For purposes of this website, actions means only those items in the above that are published in the Federal Register.
  • Administrator-Signed Rules - EPA's Administrator-Signed rules are only those published actions which are signed by the Administrator and which modify or propose to modify the Code of Federal Regulations (CFR) and therefore, contain rule text. (The CFR is the official record of all regulations created by the federal Government.). Generally speaking, they are among the most complex and technical rules written by EPA.
  • Advance Notice of Proposed Rulemaking – An Advance Notice of Proposed Rulemaking (ANPRM) is intended to solicit input and/or information from all segments of the public interested in a particular issue prior to an agency determining whether to propose a rulemaking. As such, it does not propose or impose any regulatory requirements. EPA may choose to develop an ANPRM for actions which are still in the early stages of development and for which public input may be particularly helpful to the action.
  • Code of Federal Regulations (CFR) - The Code of Federal Regulations (CFR) is the official record of all regulations created by the federal government. Congress established by law the Federal Register (FR) and the CFR to provide a central publication system for all Federal Department and Agencies and to allow citizens to have an efficient way to know which regulations affect them.
  • Development Time - The average time it takes the Agency to develop a rule from initiation to when a rule is finalized and published in the Federal Register. The development time will always vary and is influenced by a variety of factors which include but are not limited to, judicial or court deadlines, the amount of data gathering required, the level of stakeholder involvement and the overall complexity of the rulemaking.
  • Direct Final Rule – A direct final rule is a rule that is issued in final form, without prior notice and comment, that becomes effective on a specific future date unless adverse comment is received within a specified period before that date.
  • Fast-Track Rule – A fast-track rule is an action that is both proposed and finalized in the same calendar year.
  • Federal Register - The Federal Register (FR) is an official daily publication for agency rules, proposed rules, and notices of Federal agencies and organizations, as well as for Executive Orders and other presidential documents. Final rules published in the FR are the basis for updating the Code of Federal Regulations (CFR), which contains each Agency’s rules in a standard, 'codified' format. Both the FR and the CFR are published by the Office of Federal Register (OFR) within the National Archives and Records Administration (NARA). To learn more, visit the Federal Register website at http://www.gpo.gov/fdsys/browse/collection.action?collectionCode=FR.
  • Final Rule – A final rule is the conclusion of the Agency's regulatory development. For purposes of this website, a final rule represents a range of documents that are published in the Rules section of the Federal Register, such as final rules that amend the CFR by adding new text or by revising or removing existing text or other types of final actions or documents that have no regulatory text and do not amend CFR but affect the Agency such as general policy statements, final guidance documents or petitions for reconsideration.
  • "Headquarters Other" - "Headquarters Other" is a category of published actions which originate from the Headquarters Program Offices. These can include rules, policy statements, guidance documents and notices and are not "Administrator-Signed Rules."
  • Notice – A notice is a document that is published in the "Notices" section of the Federal Register and provides information of interest to the public. Examples include notices about public hearings and meetings or notices about the availability or extension of public comment periods.
  • Notice of Proposed Rulemaking - A Notice of Proposed Rulemaking (NPRM) proposes to add, change, or delete regulatory text, provides an explanation for the Agency's action, and contains a request for public comments. For purposes of this website, supplemental NPRMs and notices of data availability are also included in this category classification.
  • "Regional Other" - "Regional Other" is a category of published actions which originate from the EPA Regions. These can include rules, policy statements, guidance documents and notices and are not “Administrator-Signed Rules.”
  • Regulatory Review - Executive Order 12866 describes a process whereby OMB's Office of Information and Regulatory Policy (OIRA) reviews some EPA rules. At the same time, OIRA may coordinate review by other federal agencies. OIRA decides which rules will undergo regulatory review and which rules will not. If a rule undergoes regulatory review, then EPA describes to the public any Administrator-Signed changes made to the rule as a result of the review.
  • Regulatory Stage – For this website, regulatory stage means one of the five types of documents EPA publishes in the Federal Register: Notices, Notices of Proposed Rulemaking, Direct Final Rules, Final Rules, and Advance Notices of Proposed Rulemaking.
  • Rule – A rule is "the whole or a part of an agency statement of general or particular applicability and future effect designed to implement, interpret, or prescribe law or policy or describing the organization, procedure, or practice requirements of an agency." 5 U.S.C. 551(4)
  • "Significant" regulatory action - "Significant" regulatory action is a term used during regulatory reviews under Executive Order 12866. EO 12866 defines "significant" regulatory action as any regulatory action that is likely to result in a rule that may:
    1. Have an annual effect on the economy of $100 million or more or adversely affect in a material way the economy, a sector of the economy, productivity, competition, jobs, the environment, public health or safety, or State, local, or tribal governments or communities;
    2. Create a serious inconsistency or otherwise interfere with an action taken or planned by another agency;
    3. Materially alter the budgetary impact of entitlements, grants, user fees,
    4. or loan programs or the rights and obligations of recipients thereof; or
    5. Raise novel legal or policy issues arising out of legal mandates, the President’s priorities, or the principles set forth in this Executive order.
