Its just in the US jurisdiction for leases. Basically, if you draw a horizontal line from the tip of Texas, anything north of that is leased by the US. From the La coast, we can go around 300 miles.
The U.S. jurisdiction is claimed out to 200 nm from the coast in the EEZ. The Exclusive Economic Zone is based on the 1982 Law of the Sea Treaty. This has NEVER been ratified, so how is the feds claim of jurisdiction legit?
