In accordance with Article 1(b) of the Additional Protocol, the United States shall not permit any wide-area environmental sampling proposed by the IAEA to be conducted at a specified location in the United States under Article 9 of the Additional Protocol unless the President has determined and reported to the appropriate congressional committees with respect to that proposed use of environmental sampling that— (1) the proposed use of wide-area environmental sampling is necessary to increase the capability of the IAEA to detect undeclared nuclear activities in the territory of a non-nuclear-weapon State Party; (2) the proposed use of wide-area environmental sampling will not result in access by the IAEA to locations, activities, or information of direct national security significance; and (3) the United States— (A) has been provided sufficient opportunity for consultation with the IAEA if the IAEA has requested complementary access involving wide-area environmental sampling; or (B) has requested under Article 8 of the Additional Protocol that the IAEA engage in complementary access in the United States that involves the use of wide-area environmental sampling.
