Significant Guidance Documents

EPA maintains a list of significant guidance documents as called for by the Office of Management and Budget's (OMB) Final Bulletin for Agency Good Guidance Practices (PDF) (GGP Bulletin) (23 pp, 158K, About PDF). Please be aware that the lists do not include every guidance document issued by EPA. They only encompass those documents that are "significant" as defined by the GGP Bulletin.

EPA's Procedures for Significant Guidance Documents

OMB established good guidance practices to ensure that guidance documents of executive branch departments and agencies are:

  • developed with appropriate review and public participation,
  • accessible and transparent to the public,
  • of high quality, and
  • not improperly treated as legally binding requirements.

In keeping with these goals, OMB has directed agencies to develop procedures for creating, issuing, and using significant guidance documents and economically significant guidance documents.

Among other things, EPA's procedures include:

  • Posting a list of significant guidance documents currently in effect on our website - Our list is available sorted by environmental topic.
  • Establishing and clearly advertising on our website a way for the public to comment electronically on significant guidance documents. We use the interagency Web portal for public comments. Instructions for commenting are provided with our significant guidance list.
  • Providing a means for the public to comment about how well we are complying with the GGP Bulletin. As explained in the next section, we have established a significant guidance comment page that offers several ways to submit your comments.
  • For the subset of significant guidance documents that 1) qualify as "economically significant" and 2) were begun after January 25, 2007, EPA also:
    • announces that such a document is being drafted,
    • accepts comments on the draft, and
    • posts a response-to-comments document. (See section IV(1) of the GGP Bulletin for details.)

Currently, there are no EPA guidance documents in this subset. When EPA develops such documents, we plan to announce that they are open for comment by publishing a notice in the Federal Register. The notice will generally include instructions for providing comments, including how to find and comment on the document at Additionally, we plan to post our response-to-comments documents at

Note that we do not intend to post draft economically significant guidance documents on this site. You will need to consult the Federal Register to read and comment on such drafts.
