Pole treatment. Poles in place are exposed to weathering and decay, which is usually most severe at the ground line. In some cases, the upper part of the pole will have decayed to only a small degree, and preservative treatment to extend its useful life will be economical. Poles may have to be straightened because deterioration or replacement has caused them to be out of line. Guying, raking, or otherwise sustaining the pole load may permit line straightening, if the butt of the pole is kicked over while leaving the top of the pole in the same place, or if both the top and the butt of the pole are moved as necessary. Moving the butt means that groundline treatment will also be necessary. The cost of pole replacement, particularly of a large, heavily-loaded pole, can justify considerable effort and expense in extending the useful life of a pole in place. See section VI for information on treatment.
