After publication of such regulations, no privately owned lands shall be acquired by the Secretary by condemnation unless he determines, in his judgment, that such lands are being used, or are in imminent danger of being used, in a manner incompatible with the regulations established pursuant to this section or unless such lands are determined to be necessary for access or development, in which case such acquisitions shall be subject to the 5 per centum limitation established in section 460aa–2(a) of this title.
