Map Number: 201001033 Date: March 18, 2010 Projection: Louisiana State Plane South, NAD 27 Source: GDT 2005; U.S. Supreme Court (Louisiana Boundary Case); EPA Coastal Subcatagory(40 CFR Part 435); NOAA Maritime Limits; DNR Offshore Area and Boundaries Louisiana Coastal Boundaries and Maritime Limits Territorial Sea The territorial sea is delimited either from base points on the land mass (normally at the low-water line along the coast) or from baselines connecting such points in accordance with international law. The coastal state enjoys sovereignty and jurisdiction over the territorial sea subject to the right of innocent passage for foreign vessels. The maximum breadth of the territorial sea allowed under international law as reflected in the LOS Convention is twelve nautical miles. Contiguous Zone Presidential Proclamation No. 7219 on August 2, 1999 extended the Contiguous Zone from its prior limit of 12 nautical miles from the baseline to 24 nautical miles. Under international law, a contiguous zone is an area contiguous to a nation's territorial sea and in which the nation may exercise the control necessary to prevent infringement of its customs, fiscal, sanitation, or immigration laws and regulations within its territory or territorial sea. It may also exercise the control necessary to punish infringement of the above laws and regulations committed within its territory or territorial sea. This Proclamation has limited immediate effect, because the contiguous zone is defined in various statutes and regulations in such a manner as to mean 12 nautical miles. As an example, the Federal Water Pollution Control Act (FWPCA) and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) both limit the contiguous zone to 12 nautical miles.
