The October 3rd issue of the Post Dispatch had an interesting article about the tree-trimming guidelines that were approved yesterday.
The article, authored by Jeffrey Tomich follows:
Missouri utility regulators approved tree-trimming guidelines for electric utilities Tuesday, ending debate over how often utilities must prune branches and limbs growing near power lines and how much they must cut.
The rules are an outgrowth of widespread storm-related power outages in AmerenUE’s service area last year and establish guidelines for how much to trim around power lines according to voltage. They require companies to notify customers before trimming trees on private property, and utilities must seek permission from customers to cut down problem trees outside
the right of way.
Utilities also are required to trim power lines in cities every four years and every six years in rural areas, do visual inspections and make periodic reports to the Public Service Commission.
“I think (the new rules) are going to improve reliability,” said JeffDavis, PSC chairman. But “it’s going to take some time to get them phased in.”
Commissioner Robert Clayton III voted against the rules. He and former Commissioner Steve Gaw had sought to adopt tougher statewide tree-trimming guidelines, but their proposals were pruned after utilities balked.
Ameren and other investor-owned utilities in Missouri warned that the rules, as proposed, would have cost more than $300 million to implement, and those costs could be passed on to customers in higher rates.
“These rules are a mixed bag,” Clayton said Tuesday. “I think the public expected us to take stronger action on reliability.”
Among the provisions cut out of the original rules were specific
penalties for violations. Davis said that was done because the penalty provisions were already in the law.
“The statute speaks for itself,” he said. “We don’t need to be
repeating it in every rule that we draft.”
Davis said the rules provide customers 90 percent of the benefit of the Clayton and Gaw versions but at a tiny fraction of the cost.
St. Louis-based AmerenUE said it is content with the outcome.
“These are rules we can live with,” spokeswoman Susan Gallagher said. “We believe they increase requirements for tree trimming and communications with customers and transparency.”
