(1) New Transmission Lines for Which Construction Was Commenced After March 21, 1989.
    (a) Compliance with the electric field standards set forth in Fl. Admin. Code R. 62-814.450, shall be determined by calculations using the highest operating voltage for a new transmission line, together with parallel transmission lines then existing in the ROW.
    (b) Compliance with the magnetic field standard set forth in Fl. Admin. Code R. 62-814.450, shall be determined by calculations at the MCR current for a new transmission line, together with parallel transmission lines then existing in the ROW.
    (c) Where calculations under this section indicate that operation of existing electrical facilities on an existing ROW produces electric or magnetic fields at levels higher than the limits specified for new facilities in Fl. Admin. Code R. 62-814.450, a new electrical facility may be constructed and operated on that existing ROW provided that the new facility does not increase the electric or magnetic fields above the maximum field values created by the existing line. Where calculations under this section indicate that the existing electrical facility produces field strengths less than the limits in Fl. Admin. Code R. 62-814.450, then the limits in Fl. Admin. Code R. 62-814.450, shall apply.
    (d) Measurements shall be made in conformance with the criteria of Fl. Admin. Code R. 62-814.460, above.
    (2) New Substations for Which Construction Was Commenced After March 21, 1989.
    (a) Compliance with the electric field standard set forth in Fl. Admin. Code R. 62-814.450, shall be determined by calculations using the highest operating voltages for the entering and exiting new transmission lines together with existing transmission lines associated with the substation and shall be equal to the maximum edge of ROW electric field of any new transmission line entering or exiting the substation property boundary calculated pursuant to subsection (1).
    (b) Compliance with the magnetic field standard set forth in Fl. Admin. Code R. 62-814.450, shall be determined by calculations using the MCR current of the entering and exiting new transmission lines together with existing transmission lines associated with the substation and shall be equal to the maximum value of the edge of ROW magnetic field of any new transmission line entering or exiting the substation property calculated pursuant to subsection (1).
    (3) Access. Department employees shall have access to all electrical facilities with reasonable notice to the facility owner for the purpose of determining compliance in accordance with Florida Statutes § 403.091
