Title: Clean Water Act
Short Name: CleanWaterAct
Status: Completed
Publication Date: 2016-11-09
Abstract:

These data represent geographic terms used within the Clean Water Act (CWA). The CWA establishes the basic structure for regulating the addition of pollutants (discharges) into waters of the United States, a three mile territorial sea, a 12 mile contiguous zone, and the ocean. The goal of the CWA is to restore and maintain the chemical, physical, and biological integrity of the Nation's waters. This data includes two component boundaries, which delineate the seaward extent of various parts of the CWA. The boundary of a three mile territorial sea and 12 mile contiguous zone are relevant to application of various discharge standards associated with vessels or other floating craft, that vary depending on operational status. As referenced within the CWA, these two boundaries are based on the 1958 Convention on the Territorial Sea and the Contiguous Zone, and not the contemporary extent of these respective boundaries. While the Exclusive Economic Zone (EEZ) is not specified with the CWA, it is denoted here for illustrative purposes. The CWA does not include inland waters because 1) it is difficult to properly identify the nationwide extent of all inland water bodies, and 2) there is current litigation with EPA of such water bodies falling under the jurisdiction of the CWA. When investigating geo-regulatory boundaries near the boundary edges, users should consult the most up-to-date applicable jurisdictional boundaries from all respective authoritative sources.

Data Use Constraints:

These data are intended for coastal and ocean use planning. Not for navigation. These data represent the unofficial boundary of the Clean Water Act (CWA), as of 2016. The CWA does not include inland waters because 1) it is difficult to properly identify the nationwide extent of all inland water bodies, and 2) there is current litigation with EPA of such water bodies falling under the jurisdiction of the CWA. When investigating geo-regulatory boundaries near the boundary edges, users should consult the most up-to-date applicable jurisdictional boundaries from all respective authoritative sources. For the official boundary, please reference language within the authoritative legislation and consult the governing agency/agencies.

Process Steps

Process Step 1

CC ID: 651503
Description:

1. Acquired national shoreline/s from authoritative sources (NOAA, BOEM, and NGA) to use as the inland extent of the Clean Water Act (CWA) boundary.

2. Acquired international borders (Canada and Mexico) from authoritative sources (OCS and USGS, respectively).

3. Acquired the seaward Clean Water Act line work (OCS 3nm line, Territorial Sea, Exclusive Economic Zone) from NOAA OCS and NOAA OCM. Acquired NOAA 3nm line work from OCS (via email) for entire nation and territories. The Territorial Sea was extracted from the OCS Maritime Boundaries and Limits data. The Exclusive Economic Zone was derived from the Energy Policy Act boundary via MarineCadatsre.gov.

4. Created a national polygon shoreline, using the various shoreline sources and international borders. This was used as the landward extent of the CWA boundary. (NOTE: in northeast Alaska, the BOEM shoreline and OCS international boundary did not intersect. Used the NGA shoreline to close the small gap between these two sources.)

5. The seaward extent of the CWA boundary was generated using three marine boundaries: OCS 3nm line, Territorial Sea, and EEZ. Special notes on generating these boundaries are as follows:

6. Small gaps in the line work for the Territorial Sea were corrected. These (six) gaps were located in Alaska and Louisiana, and were closed by creating a straight line between the two end nodes.

7. In a few places in Maine and Alaska, OCS 3nm line was extended, where it was needed to intersect with the EEZ and Territorial Sea. This was performed by extending the line parallel to the bearing of the line at its terminus. Generally, these extensions were very short - usually less than 5 feet. Similarly, the Territorial Sea line was extended offshore of Texas, where it did not extend far enough south to intersect the EEZ boundary.

8. Territorial Sea line was extended offshore of Washington state by following the line of the state's Coastal Zone Management Act boundary. In Washington state, the Territorial Sea line intentionally ends miles short of and does not intersect with the EEZ boundary.

9. Three small gaps (about 1-4nm in length) in the OCS 3nm line work were noted in southeast Alaska (all on the eastern side of chart 17320). These were manually closed using the BOEM Submerged Lands Act boundary.

10. Visually inspected boundary extents to make sure they were coincident to respective data source boundaries.

11. Combined all three component marine boundaries (i.e. OCS 3nm line, Territorial Sea, Exclusive Economic Zone) into one layer.

12. Added fields and populated according to data dictionary.
