FAR and DFARS › FAR Part 1: Federal Acquisition Regulations System › Subpart 1.5

FAR 1.501-3 Exceptions.

The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.

In plain English

This section lists exceptions to the normal requirement to ask for public comments on proposed FAR changes. It matters to contractors because it explains when a rule can take effect without advance comments, though urgent changes must still be temporary and allow at least a 30-day comment period.

Applies to: Proposed FAR coverage and the agencies issuing it

What it requires

  • Issue urgent coverage on a temporary basis
  • Provide for at least a 30 day public comment period for such temporary coverage

Key terms: significant revision · advance comments · urgent and compelling circumstances · temporary basis · public comment period

The text

(a) Comments need not be solicited when the proposed coverage does not constitute a significant revision.

(b) Advance comments need not be solicited when urgent and compelling circumstances make solicitation of comments impracticable prior to the effective date of the coverage, such as when a new statute must be implemented in a relatively short period of time. In such case, the coverage shall be issued on a temporary basis and shall provide for at least a 30 day public comment period.
