S.C. Code § 27-2-50
For purposes of more precisely defining the South Carolina Coordinate System, the following definition by the National Ocean Survey and the National Geodetic Survey is adopted:
The South Carolina Coordinate System is a Lambert conformal projection of the North American Datum, 1983, having standard parallels at north latitudes 32° 30' and 34° 50', along which parallels the scale must be exact. The origin of coordinates is at the intersection of the meridian 81° 00'west of Greenwich and the parallel 31° 50' north latitude. This origin is given the coordinates: * = 2,000,000 feet and y = 0 feet. For the purposes of the South Carolina Coordinate System, the foot is the International Foot with one inch being exactly equal to 2.54 centimeters.
The position of South Carolina Coordinate System is as marked on the ground by monumented points of the North American Horizontal Geodetic Control Network established in conformity with standards adopted by the Federal Geodetic Control Committee for first-order and second-order work, whose geodetic positions have been rigidly adjusted on the North American Datum of 1983, and whose coordinates have been computed on the system defined in this section. Any such stations may be used for establishing a survey connection with the South Carolina Coordinate System.
