22 U.S.C. § 8153

In accordance with Article 1(b) of the Additional Protocol, the United States shall not permit any location-specific environmental sampling in the United States under Article 5 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 location-specific 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 location-specific environmental sampling will not result in access by the IAEA to locations, activities, or information of direct national security significance; and (3) with respect to the proposed use of environmental sampling, the United States— (A) has been provided sufficient opportunity for consultation with the IAEA if the IAEA has requested complementary access involving location-specific 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 location-specific environmental sampling.
