System protection upgrades will be required at NYPA's Niagara substation and NYSEG Corporation's Kintigh substation. 5.2   Design Standards The structures will be designed in accordance with applicable national and state codes and regulations and the Applicant’s own standards. The most significant regulation is the National Electrical Safety Code (“NESC”). The NESC specifies both the minimum structural loads to determine the required structural capacity and minimum clearances to energized parts and wires, to ground, to adjacent transmission lines, to railroad lines, to buildings, and to a host of other facilities. The NESC, as well as other, more stringent criteria that may be imposed by RGE, will govern the structural loading. Eight basic load conditions are considered by RGE for all new lines on the transmission system. 1) NESC Heavy Loading Grade B Construction, Rule 250B which is the application of ½-inch radial ice and 4 PSF wind at a wire temperature of 0°F. 2) NESC Extreme Wind Loading, Rule 250C  which is the application of 90 mph wind. 3) NESC Extreme Ice with Concurrent Wind Loading, Rule 250D  which is the application of 1-inch radial ice and 4 PSF wind at a wire temperature of 15°F. 4) Heavy Ice Loading which is the application of 1½-inch radial ice with no wind at a wire temperature of 0°F. 5) High Wind Loading which is the application of 20 PSF wind pressure on bare wire at a wire temperature of 60°F.
