Jefferson County PUD maintains a rigorous tree-maintenance program for trees along power line rights-of-way. Trees are our number one cause of outages and approximately 90 percent of tree-related outages are caused by trees growing outside of the right-of-way
Trees that grow too close to power lines can cause outages, start fires or create other hazardous conditions. Generally, we remove trees that pose a serious threat to safety and electric service. Not only does this work help maintain electric safety and service reliability, it is mandated by state and federal regulations (NESC Rules 012, 013, and 218; IEEE Standard 516-2003, Section 126.96.36.199; ANSI Z133.1; OSHA 1910; and WAC 296-45).
