(1)(A) Any interim consumer product safety standard established pursuant to this section shall be enforced in the same manner as any other consumer product safety standard until such time as there is in effect a final consumer product safety standard promulgated by the Commission, as provided in subparagraph (B), or until such time as it is revoked by the Commission under section 2058(e) of this title. A violation of the interim consumer product safety standard shall be deemed to be a violation of a consumer product safety standard promulgated by the Commission under section 2058 of this title.
(B)
(2)(A) Until there is in effect such a final consumer product safety standard, the Commission shall incorporate into the interim consumer product safety standard, in accordance with the provisions of this paragraph, each revision superseding the requirements for flame resistance and corrosiveness referred to in subsection (a) and promulgated by the General Services Administration.
(B) At least 45 days before any revision superseding such requirements is to become effective, the Administrator of the General Services Administration shall notify the Commission of such revision. In the case of any such revision which becomes effective during the period beginning on February 1, 1978, and ending on July 11, 1978, such notice from the Administrator of the General Services Administration shall be deemed to have been made on July 11, 1978.
(C)(i) No later than 45 days after receiving any notice under subparagraph (B), the Commission shall publish the revision, including such changes in the revision as it considers appropriate to make the revision suitable for promulgation as an amendment to the interim consumer product safety standard, in the Federal Register as a proposed amendment to the interim consumer product safety standard.
(ii) The Commission may extend the 45-day period specified in clause (i) for an additional period of not more than 150 days if the Commission determines that such extension is necessary to study the technical and scientific basis for the revision involved, or to study the safety and economic consequences of such revision.
(D)(i) Additional extensions of the 45-day period specified in subparagraph (C)(i) may be taken by the Commission if—(I) the Commission makes the determination required in subparagraph (C)(ii) with respect to each such extension; and(II) in the case of further extensions proposed by the Commission after an initial extension under this clause, such further extensions have not been disapproved under clause (iv).
(ii) Any extension made by the Commission under this subparagraph shall be for a period of not more than 45 days.
(iii) Prior notice of each extension made by the Commission under this subparagraph, together with a statement of the reasons for such extension and an estimate of the length of time required by the Commission to complete its action upon the revision involved, shall be published in the Federal Register and shall be submitted to the appropriate Congressional committees.
(iv) In any case in which the Commission takes an initial 45-day extension under clause (i), the Commission may not take any further extensions under clause (i) if each committee referred to in clause (iii) disapproves by committee resolution any such further extensions before the end of the 15-day period following notice of such initial extension made by the Commission in accordance with clause (iii).
(E) The Commission shall give interested persons an opportunity to comment upon any proposed amendment to the interim consumer product safety standard during the 30-day period following any publication by the Commission under subparagraph (C).
(F) No later than 90 days after the end of the period specified in subparagraph (E), the Commission shall promulgate the amendment to the interim consumer product safety standard unless the Commission determines, after consultation with the Secretary of Energy, that—(i) such amendment is not necessary for the protection of consumers from the unreasonable risk of injury associated with flammable or corrosive cellulose insulation; or
(ii) implementation of such amendment will create an undue burden upon persons who are subject to the interim consumer product safety standard.
(G) The provisions of section 2060 of this title shall not apply to any judicial review of any amendment to the interim product safety standard promulgated under this paragraph.
