"(2) Not later than sixty days after submittal of the list under paragraph (1) of t^iis subsection the Administrator shall promulgate each such list with such modifications as he deems necessary.

"(4) Any region or portion thereof which is not classified under subparagraph (B) or (C) of paragraph (1) of this subsection for sulfur dioxide or particulate matter within one hundred and eighty days after enactment of the Clean Air Act Amendments of 1977 shall be deemed to be a region classified under subparagraph (D) of paragraph (1) of this subsection. "(5) A State may from time to time review, and as appropriate revise and resubmit, ithe list required under this subsection. The Administrator shall consider and promulgate such revised list in accordance with this subsection. "(e)(1) Except as otherwise provided in paragraph (2), the Governor of each State is authorized, with the approval of the Administrator, to redesignate from time to time the air quality control regions within such State for purposes of efficient and effective air quality management. Upon such redesignation, the list under subsection (d) shall be modified accordingly. "(2) In the case of an air quality control region in a State, or part of such region, which the Administrator finds may significantly affect air pollution concentrations in another State, the Governor of the State in which such region, or part of a region, is located may redesignate from time to time the boundaries of so much of such air quality control region as is located within such State only with the approval of the Administrator and with the consent of all Governors of all States which the Administrator determines may be significantly affected. "(3) No compliance date extension granted under section 113(d) (5) (relating to coal conversion) shall cease to be effective by reason of the regional limitation provided in section 113(d)(6) if the violation of such limitation is due solely to a redesignation of a region under this subsection."
