Title 42 › Chapter CHAPTER 99— - OCEAN THERMAL ENERGY CONVERSION › Subchapter SUBCHAPTER IV— - MISCELLANEOUS PROVISIONS › § 9163
Ocean thermal energy conversion (OTEC) facilities and plantships that are licensed under this chapter and sit seaward of the high‑water mark must follow the U.S. Constitution, laws, and treaties just as if they were on federal land inside a State. They do not count as islands and have no territorial seas. State and federal roles inside the territorial sea stay the same, but if a licensed OTEC facility beyond the territorial sea is hooked to a nearby coastal State by cable or pipeline, the law of that nearest State becomes U.S. law for that facility—so long as it does not conflict with this chapter or other federal rules. State tax laws do not reach past a State’s seaward boundary, and applicable laws outside that boundary are enforced by U.S. officers and courts. For customs, U.S.-documented, licensed OTEC facilities and plantships are treated as vessels. Except where customs laws apply to U.S.-documented vessels, the customs statutes (including the Tariff Act of 1930 (19 U.S.C. 1202) and other laws in title 19) generally do not apply to those facilities, but any foreign parts brought in to build them must first be made subject to the duties and taxes that would apply if they were imported for consumption into the United States and those duties must be paid.
