Wasco County Commissioner Rod Runyon says road issues played a large part in an Association of Oregon Counties Legislative Committee meeting in preparation for the upcoming legislative session in Salem.  Runyon says there is a belief a state gas tax increase of around four cents a gallon is coming, but an Oregon Association of Surveyors and Engineers proposal of how to divide up that increase was of interest in particular to smaller counties.  It would divide one-third of it equally among all counties regardless of size, one-third based on motor vehicle registrations, and the rest based on mileage.  Runyon says under that plan with a four-cent gas tax increase, Wasco County could realize $500,000 to $600,000 in additional revenue.  The current gas tax is divided by motor vehicle registration numbers, and that won’t change.
