Pole Cost x SS + Pole Cost x US x % US = Maximum Annual Rate
N
WHERE:
Pole Cost = Annual operation and maintenance expense attributable to the entire pole
PLUS
Annual fixed changes for depreciation, property taxes, return, and related income taxes on capital attributable to the pole, based upon embedded cost of average bare pole less 15% (5% for telecommunications utilities) for cross-arms and other non-pole related items.
SS = Percentage of total average bare pole allocated as "support component."
N = Total number of public utilities and attaching entities making use of the pole [a reasonable system-wide average based on an actual physical inventory not more than three (3) years old may be used.]
US = Percentage of total average pole allocated as "usable space."
%US = Percentage of usable space allocated to attaching entity.
For purposes of this §7.2.2:
32.5 feet for telephone utility poles
37.5 feet for electric utility poles.
Parties to an attachment agreement may establish such one-time "make-ready" charges as they can agree upon provided that the amounts so established must bear a reasonable relationship to the actual one-time costs incurred by the host utility in making the facility available for attachment.
