Subject to the provisions of chapter 15 of title 44 and regulations prescribed under the authority thereof, the rules and regulations of the Commission under this subchapter, and amendments thereof, shall be effective upon publication in the manner which the Commission shall prescribe, or upon such later date as may be provided in such rules and regulations.

Notice to interested persons, if any, other than parties may be given in the same manner or by publication in the Federal Register.
No provision of this subchapter imposing any liability shall apply to any act done or omitted in good faith in conformity with any rule, regulation, or order of the Commission, notwithstanding that such rule, regulation, or order may, after such act or omission, be amended or rescinded or be determined by judicial or other authority to be invalid for any reason.
