Current through Reg. 50, No. 138; July 16, 2024
(1) Existing electrical facilities for which
				construction was commenced on or prior to March 21, 1989 (Reserved).
(2) New transmission lines and substations.
(a) The maximum electric field at the edge of
				the transmission line ROW containing a 500 kV nominal voltage or less
				transmission line or at the property boundary of a new substation containing
				facilities operating at these voltages shall not exceed 2.00 kV/m.
(b) The maximum electric field at the edge of
				the transmission line ROW for a line with a nominal voltage greater than 500 kV
				or at the property boundary of a new substation containing facilities operating
				at these voltages shall not exceed 5.50 kV/m.
(c) The maximum electric field on the ROW of
				a 230 kV or smaller transmission line shall not exceed 8 kV/m.
(d) The maximum electric field on the ROW of
				a transmission line with a nominal voltage greater than 230 kV and up to 500 kV
				shall not exceed 10 kV/m.
(e) The
				maximum electric field on the ROW of a transmission line greater than 500 kV
				shall not exceed 15 kV/m.
(f) The
				maximum magnetic field at the edge of a 230 kV or smaller transmission line ROW
				or at the property boundary of a new substation serving such lines shall not
				exceed 150 milliGauss.
(g) The
				maximum magnetic field at the edge of the transmission line ROW for a
				transmission line with a nominal voltage greater than 230 kV and up to 500 kV
				or at the property boundary of a new substation containing facilities operating
				at these voltages shall not exceed 200 milliGauss, except for double circuit
				500 kV lines to be constructed on ROWs existing on March 21, 1989, as
				identified below where the limit will be 250 milliGauss.
(h) The maximum magnetic field at the edge of
				the transmission line ROW for a transmission line with a nominal voltage
				greater than 500 kV or at the property boundary of a new substation containing
				facilities operating at these voltages shall not exceed 250
				milliGauss.
(i) For existing ROWs
				extending from the Andytown substation to the Orange River substation, Andytown
				substation to the Martin Generating Plant, and the Martin Generating Plant to
				the Midway substation, where the facility owner has acquired, prior to March
				21, 1989, a ROW sufficiently wide for two or more 500 kV transmission lines and
				has constructed one or more 500 kV transmission lines on this ROW prior to
				March 21, 1989, the maximum magnetic field at the edge of the ROW or property
				boundary of a new or modified substation shall not exceed 250 milliGauss.
