s) The Corps must authorize any power transmission line crossing a
navigable water of the United States unless the lines are part of a water power project
subject to the control of the Federal Energy Regulatory Commission. Transmission lines
crossing navigable waters are required to have a minimum clearance over the navigable
channel provided by existing fixed bridges, or the clearances which would be required by
the US Coast Guard for new fixed bridges in the vicinity of the proposed power line
crossing. The minimum additional clearance above clearance required for bridges for the
low point of the line under conditions which produce the lowest sag is given below for
various system voltages as outlined in the National Electrical Safety Code.
