Once the selection of a site is effective under section 10166 of this title, the requirements of the National Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.) shall apply with respect to construction of a monitored retrievable storage facility, except that any environmental impact statement prepared with respect to such facility shall not be required to consider the need for such facility or any alternative to the design criteria for such facility set forth in section 10161(b)(1) of this title.

Nothing in this section shall be construed to limit the consideration of alternative facility designs consistent with the criteria described in section 10161(b)(1) of this title in any environmental impact statement, or in any licensing procedure of the Commission, with respect to any monitored retrievable storage facility authorized under section 10162(b) of this title.

construction of such facility may not begin until the Commission has issued a license for the construction of a repository under section 10135(d) 1 of this title;

construction of such facility or acceptance of spent nuclear fuel or high-level radioactive waste shall be prohibited during such time as the repository license is revoked by the Commission or construction of the repository ceases;

the quantity of spent nuclear fuel or high-level radioactive waste at the site of such facility at any one time may not exceed 10,000 metric tons of heavy metal until a repository under this chapter first accepts spent nuclear fuel or solidified high-level radioactive waste; and

the quantity of spent nuclear fuel or high-level radioactive waste at the site of such facility at any one time may not exceed 15,000 metric tons of heavy metal.
