# §601.22. General.

- (a) Unless the Administrator, for good cause, finds a notice is impractical, unnecessary, or contrary to the public interest, and incorporates such a finding and a brief statement of the reasons for it in the rule, a notice of proposed rulemaking must be issued, and interested persons are invited to participate in the rulemaking proceedings involving rules under an Act.
- (b) For rules for which the Administrator determines that notice is unnecessary because no adverse public comment is anticipated, the direct final rulemaking procedure described in [§ 601.36](/cfr/49/601.36.md) may be followed.
