The draft of any environmental impact statement required under the National Environmental Policy Act of 1969 [42
et seq.] in connection with any application filed under this section shall be completed, within nine months from the date of filing, by the head of the Federal agency assigned lead responsibility for the statement. Any such statement shall be jointly prepared by all Federal agencies with which the application was filed under subsection (c) of this section. The final environmental impact statement shall be completed within one year from the date of such filing. Such nine-month and one-year periods may be extended for good cause by the Federal agency head assigned lead responsibility for the preparation of such statement if he determines that additional time is necessary for such preparation, notifies the applicant in writing of such determination, and publishes notice of such determination, together with the reasons therefor, in the Federal Register. The provisions of section
shall apply to each environmental impact statement under this subsection in the same manner as such provisions apply to applications relating to the public lands referred to in section
. The Federal agency assigned lead responsibility shall, in conjunction with such other Federal agencies before which the application is pending, hold public hearings in the District of Columbia and an appropriate location in the State on each draft joint environmental impact statement and the views expressed therein shall be considered by all Federal agencies concerned before publication of the final joint environmental impact statement.
