Understanding the relationship between laws and regulations

Laws provide the authority for EPA and other executive agencies to write regulations. Regulations explain the technical, operational, and legal details necessary to implement laws.

Before federal agencies can implement a regulation/rule, they must do the following:

  • Determine whether the rule is necessary.
  • Submit the proposed rule to the Office of Management and Budget (OMB) for review.
  • If the proposal is approved, the agency prepares a draft version of the proposed rule.
  • The proposed rule is published in the Federal Register and made available for public comment.
  • After comments are reviewed and incorporated, the rule is again submitted to the Office of Management and Budget (OMB) for review.
  • After the final rule is approved by OMB, the final rule is published in the Federal Register.

All general and permanent rules published in the Federal Register by the Executive departments and agencies of the Federal Government are codifed and made available through the Code of Federal Regulations (CFR). Title 40 (Protection of Environment) of the Code of Federal Regulations (CFR) contains most regulations pertaining to the Environment.
