Except as otherwise provided in this subchapter, prior to commencing exploration pursuant to any oil and gas lease issued or maintained under this subchapter, the holder thereof shall submit an exploration plan to the Secretary for approval. Such plan may apply to more than one lease held by a lessee in any one region of the outer Continental Shelf, or by a group of lessees acting under a unitization, pooling, or drilling agreement, and shall be approved by the Secretary if he finds that such plan is consistent with the provisions of this subchapter, regulations prescribed under this subchapter, including regulations prescribed by the Secretary pursuant to paragraph (8) of
section 1334(a) of this title, and the provisions of such lease. The Secretary shall require such modifications of such plan as are necessary to achieve such consistency. The Secretary shall approve such plan, as submitted or modified, within thirty days of its submission, except that the Secretary shall disapprove such plan if he determines that (A) any proposed activity under such plan would result in any condition described in
section 1334(a)(2)(A)(i) of this title, and (B) such proposed activity cannot be modified to avoid such condition. If the Secretary disapproves a plan under the preceding sentence, he may, subject to
section 1334(a)(2)(B) of this title, cancel such lease and the lessee shall be entitled to compensation in accordance with the regulations prescribed under section 1334(a)(2)(C)(i) or (ii) of this title.
