There is an actual physical basis for AT&T's position. When a pole line is designed, the poles and guys are designed for certain criteria (power poles are NESC and/or RUS plus any state specific regulations). If someone wants to attach to the same pole then the pole may not support the new attachment per NESC (for power poles) or the guying may need adjustment. Reviewing the new attachments can take time, 60 days is not unreasonable.
Along with this, the poles may need to be surveyed depending on how long the poles have been installed. Poles installed a long time ago may not have drawings and that means a field visit to collect the information.
If the party wanting to attach to a pole provides sealed drawings from an engineer that the attachments have no adverse effect, then it is usually a quick review of the submitted attachment package to make sure everything is in order.
While you're not wrong...all of the issues you mention are, in general, issues that have to be dealt with. Those issues are, however, all addressed as part of the permitting process to be allowed to attach to the poles.
What's at issue in Louisville is the make ready process after the permit has been issued (after it has been determined that the poles have enough room and are strong enough to handle the new wires).
