SDG&E may not impose upon Daniels a fee for use of transmission ROW as long as the 1986 Pole Attachment Agreement between the parties remains in effect. If the 1986 Agreement is terminated, SDG&E may charge a fee for use of its transmission ROW on private land based on its actual costs. SDG&E may not charge its proposed market-based fee of $6,080 per mile. Instead, SDG&E may calculate a transmission ROW charge as an overhead component of its transmission pole attachment fee according to the formula proposed by Complainants.
