Section 1100-2.23 - Exhibit 22: Electric and Magnetic Fields

Exhibit 22 shall contain:

(a) For the entire ROW of the proposed interconnection line, or any collection line rated over sixty-nine (69)-kV, providing the electrical interconnection between the facility, and any transmission line between the facility and the existing electric transmission and distribution system: identify every ROW segment having unique electric and magnetic field (EMF) characteristics due to structure types and average heights, ROW widths, and co-location of other transmission facilities in the ROW.

(b) For each identified ROW segment, provide both "base case" and "proposed" cross-sections to scale showing:

(1) All overhead electric transmission, sub-transmission and distribution facilities including the proposed facility showing structural details and dimensions and identifying phase spacing, phasing, and any other characteristics affecting EMF emissions;

(2) All underground electric transmission, sub-transmission and distribution facilities;

(3) All underground gas transmission facilities;

(4) All right-of-way boundaries; and

(5) Structural details and dimensions for all structures (dimensions, phase spacing, phasing, and similar categories) and include a station number identifying the location.

(c) A set of the aerial photos/drawings enhanced by showing the exact location of each:

(1) Identified ROW segment;

(2) Cross-section; and

(3) Nearest residence or occupied non-residential building in each identified ROW segment with a stated measurement of the distance between the edge of ROW and the nearest edge of the residence or building.

(d) An EMF study with calculation tables and field strength graphs for each identified ROW segment cross-section, as follows:

(1) The study shall be signed and stamped/sealed by a licensed professional engineer registered and in good standing in the State of New York;

(2) Provide the name of the computer software program used to model the facilities and make the calculations;

(3) Regarding electric fields, model the circuits at rated voltage and provide electric field calculation tables and field strength graphs calculated at one (1) meter above ground level with five (5)-foot measurement intervals depicting the width of the entire ROW and out to five hundred (500) feet from the edge of the ROW on both sides, including digital copies of all input assumptions and outputs for the calculations;

(4) Regarding magnetic fields, model the circuit phase currents equal to the summer normal, summer short term emergency (STE sum), winter- normal, and winter short term emergency (STE win) loading conditions and provide magnetic field calculation tables and field strength graphs calculated at one (1) meter above ground level with five (5)-foot measurement intervals depicting the width of the entire ROW and out to five hundred (500) feet from the edge of the ROW on both sides, including digital copies of all input assumptions and outputs for the calculations;

(5) Regarding magnetic fields, also model the circuit phase currents equal to the maximum average annual load estimated to be occurring on the power lines within ten (10) years after the proposed facility is put in operation and provide magnetic field calculation tables and field strength graphs calculated at one (1) meter above ground level with five (5)-foot measurement intervals depicting the width of the entire ROW and out to five hundred (500) feet from the edge of the ROW on both sides, including digital copies of all input assumptions and outputs for the calculations;

(6) Regarding magnetic fields, also model a "base case" with the circuit phase currents equal to the maximum average annual load currently estimated to be occurring on the existing power lines within the ROW (without construction or operation of the proposed facility) and provide magnetic field calculation tables and field strength graphs calculated at one (1) meter above ground level with five (5)-foot measurement intervals depicting the width of the entire ROW and out to five hundred (500) feet from the edge of the ROW on both sides, including digital copies of all input assumptions and outputs for the calculations; and

(7) Provide a demonstration that the facilities, including interconnection transmission lines, will conform with the Public Service Commission's Statement of Interim Policy on Magnetic Fields of Major Electric Transmission Facilities (see section 1100-15.1(m)(1)(i) of this Part) at the proposed ROW edges.
