4 Jurisdiction Anoka County Operator discretion in setting application rates?, coaching/training, 85% monitored Operator training - where and who? In-house, MnDOT training new employees, attends inhouse Do you track application rates and use data? Track operator, rate, time, concentrate on new operators, don't currently use to plan Describe salt storage Sand outside, all salt inside, elevator, dumper, conveyor Do you sweep streets, how often, what equipment? Sweep 4-5 times per year, targeted to pipes, water. Sweep in spring, use truck mounted pickup broom What changes are you considering? Slowing spinners down, 100% sensors, increased monitoring, using MgCl on bridges, monitor salt usage Anoka County Parks, varies by operator In-house for operators Track annual use At county Per truck per event, do use data Coverall, three wall.
