Section 831(f) of this title, referred to in subsec. (e)(3), (7), (9), was redesignated section 831(g) by Pub. L. 114–23, title VIII, § 812(d), June 2, 2015, 129 Stat. 312.

Section 1502(19) of title 33, referred to in subsec. (e)(13), probably should be a reference to section 3(19) of the Deepwater Port Act of 1974, which is classified to section 1502(19) of Title 33, Navigation and Navigable Waters.
