Except as provided in subsection (f) of this section, beginning ninety days after September 18, 1978, no exploration pursuant to any oil and gas lease issued or maintained under this subchapter may be undertaken by the holder of such lease, except in accordance with the provisions of this section.
(c) Plan approval; State concurrence; plan provisions
(1) 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.

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.
(2) The Secretary shall not grant any license or permit for any activity described in detail in an exploration plan and affecting any land use or water use in the coastal zone of a State with a coastal zone management program approved pursuant to section 1455 of title 16, unless the State concurs or is conclusively presumed to concur with the consistency certification accompanying such plan pursuant to section 1456 (c)(3)(B)(i) or (ii) of title 16, or the Secretary of Commerce makes the finding authorized by section 1456 (c)(3)(B)(iii) of title 16.

(d) Drilling permit
The Secretary may, by regulation, require any lessee operating under an approved exploration plan to obtain a permit prior to drilling any well in accordance with such plan.
(e) Plan revisions; conduct of exploration activities
(1) If a significant revision of an exploration plan approved under this subsection is submitted to the Secretary, the process to be used for the approval of such revision shall be the same as set forth in subsection (c) of this section.

Any permit for geological explorations authorized by this section shall be issued only if the Secretary determines, in accordance with regulations issued by the Secretary, that—
(2) the exploration will not interfere with or endanger operations under any lease issued or maintained pursuant to this subchapter; and
(h) Lands beneath navigable waters adjacent to Phillip Burton Wilderness
The Secretary shall not issue a lease or permit for, or otherwise allow, exploration, development, or production activities within fifteen miles of the boundaries of the Phillip Burton Wilderness as depicted on a map entitled “Wilderness Plan, Point Reyes National Seashore”, numbered 612–90,000–B and dated September 1976, unless the State of California issues a lease or permit for, or otherwise allows, exploration, development, or production activities on lands beneath navigable waters (as such term is defined in section 1301 of this title) of such State which are adjacent to such Wilderness.
 So in original. Probably should be “undertaken;”.
