Interim rule This type of rule may be used instead of a proposed rule when there is good cause for making a rule effective before the public has an opportunity to comment on it. (See "Good Cause Exception.") An agency may make changes to an interim rule in a follow-up document (e.g., a final rule). If no changes are made, APHIS refers to the follow-up as an affirmation of an interim rule. An interim rule contains:
- A preamble, which includes:
- an explanation of the rule
- an effective date (usually upon publication, but sometimes earlier)
- a description of any information collection requirements and the emergency approval number from the Office of Management and Budget necessary for implementing them in an interim rule
- an invitation to the public to submit comments by a specified date (usually 60 days after publication)
- an analysis of the anticipated economic effects of the rule (however, if an analysis cannot be completed before the rule is published, it may published in the follow-up final rule or affirmation, or separately).
- The additions or changes to our regulations, as they would appear in the Code of Federal Regulations.
