General Conformity Training Modules

This training is divided into four modules so you can go directly to the information you need for the various sections of the General Conformity regulations at 40 CFR part 93 subpart B:  

  • The Basics - Useful for informing top agency managers, the general public, and those new to General Conformity:
    Module I provides an overview of the program's purpose, content of the regulations, design of the program, legal requirements, and relationship to other environmental programs.  
     
  • The Key Concepts - Useful for applying General Conformity regulations, but also for informing program managers and others who need a working knowledge of the program:
    Module II provides information on preparing the applicability analysis to know whether a Federal action requires the support of a conformity demonstration and determination or whether a de minimis finding will suffice. When needed, this module provides a roadmap of the conformity evaluation process; includes requirements for demonstrating conformity; and instructions for reporting a draft and final demonstration and determination. Includes the public participation process, which includes a public review opportunity, and the reporting requirements for both a draft and final demonstration and determination. 
     
  • Details - Instructions and guidelines for preparing a General Conformity evaluation. 
    Module III contains detailed information for emission calculations, requirements for associated programs, and special situations.
     
  • Roles and responsibilities - State and Tribal requirements and responsibilities.
    Module IV provides information on State and Tribal roles and responsibilities in the evaluation of General Conformity.

A printable version of the training modules is also available.

The General Conformity regulations applies when a Federal agency proposes to take an action on its own behalf, on the behalf of another Federal agency to obtain grants, permits, approvals, etc., or on behalf of a non-Federal entity (e.g., a project sponsor) that contributes to the scope of work and provides technical information necessary for the agencies to document its General Conformity evaluation.  Individuals and organizations preparing technical documents and demonstrations for a federal agency should follow the directives of that agency.  

In each Module, words that are initially shown in bold and italics are defined in the Glossary.
