Program utilizes a mix of maintenance pruning on
entire circuits, targeted spot pruning on portions of
circuits, and spot pruning in response to customer
call ins.
Annual work plans developed from Forestry
Services field inspection data, outage data, customer
call ins, and field engineering reports
100% of transmission field inspected each year – all
hazardous situations corrected (i.e., leaning or dead
trees)
