16 U.S.C. § 392a — Provisions of section 392 extended to additional lands

This is a short, one-sentence law. It does not create new rules of its own. Instead, it takes the rules already written in section 392 of this title and says those same rules now cover more land. The land newly covered is described by cross-reference: it is the land that was added to the park, using the boundary line set out in section 391a of this title. This section does not repeat what section 392 says, and it does not describe the exact boundary itself — for both of those, a reader needs to look at those other sections directly. All this section confirms is that the earlier rule, whatever it required, now reaches this additional territory as well as the original park land it already covered.
