The seaward extent of the SLA boundary was generated in various ways, depending on the region and the respective data available. Used the NGA shoreline to close the small gap between these two sources.)ĥ.
(NOTE: in northeast Alaska, the BOEM shoreline and OCS international boundary did not intersect. This was used as the landward extent of the SLA boundary. Created a national polygon shoreline, using the various shoreline sources and international borders. (NOTE: some western Hawaiian islands have a 3nm line based on reefs, rather than the source shoreline (via NGA) extents.) The Exclusive Economic Zone (derived from the Energy Policy Act boundary) was used in places like Maine, Texas, and Washington state, where unclosed polylines in the BOEM SLA occurred over open water.Ĥ. Acquired NOAA 3nm line work from OCS (via email) for Hawaii and those areas of Alaska that do not have a BOEM-defined SLA boundary. Acquired the seaward Submerged Lands Act line work from BOEM (Lower 48 and Alaska only). Acquired international borders (Canada and Mexico) from authoritative sources (OCS and USGS, respectively).ģ. Acquired national shoreline/s from authoritative sources (NOAA, BOEM, and NGA) to use as the inland extent of the Submerged Lands Act (SLA) boundary.Ģ. To support ocean planning activities pursuant to the Executive Order Regarding the Ocean Policy to Advance the Economic, Security, and Environmental Interests of the United States, the Energy Policy Act, the National Environmental Policy Act, the Rivers and Harbors Act, and the Coastal Zone Management Act.ġ. 1301 et seq.Īuthority: agencies of several U.S. Please reference BOEM's official Submerged Lands Act Boundary in these locations to determine where this boundary is approximated and where it is official.Ĭodification: 43 U.S.C. The official delineation of the Submerged Lands Act in these locations has not yet been established by BOEM. Some boundary delineations are approximated, including areas in Hawaii, Alaska, and Washington State. The term "coast line" is "the line of ordinary low water along that portion of the coast which is in direct contact with the open sea and the line marking the seaward limit of inland waters" (43 U.S.C. The Submerged Lands Act defines "natural resources" to include oil, gas, and all other minerals, and fish, shrimp, oysters, clams, crabs, lobsters, sponges, kelp, and other marine animal and plant life," yet expressly excludes "water power, or the use of water for the production of power" 43 U.S.C. Section 1301 et seq.) grants coastal states title to natural resources located within their coastal submerged lands and navigable waters out to three geographical miles from their coastlines (three marine leagues for Texas and Florida's Gulf of Mexico coastlines).
