A Pacific Power executive says their goal is to complete system improvements and safety measures that would result in the Hood River and Mosier areas from being removed from consideration for Public Safety Power Shutoff during periods of extreme fire danger by the end of next year.  Pacificorp Vice President of External Affairs Scott Bolton said on Mid-Columbia Today on Wednesday that work done so far has already removed over 80% of the customers in the area, including all of the Hood River city limits, from the potential of a shutoff.  Measures that have been taken include new insulated conductors, new switching capabilities to isolate areas, more weather monitoring capabilities, and aggressive management of vegetation near power lines.
