## Abstract

The U.S. Army Corps of Engineers is amending the regulations in 33 CFR Part 334 to add a clause that alerts mariners that potential navigation and charting errors may occur in the boundaries of some danger zones and restricted areas as a result of the updating and replacement of the North American Datum of 1927 with the North American Datum of 1983. The promulgation of these regulations will notify mariners that geographic coordinates establishing danger zone and restricted area boundaries, promulgated in 33 CFR Part 334 are not to be used for plotting on maps and charts where NAD 83 is referenced unless the geographic coordinates in the regulations are expressly labeled ``NAD 83''. Geographic coordinates without the NAD 83 reference may be plotted on charts or maps which are referenced to NAD 83 only after applying the correct formula that is published on the map or chart being used.
