The Department of Social and Health Services said Monday it sent a mobile Customer Service Office to Keller in Ferry County to assist residents who need access to services. The mobile office will allow residents access to Basic Food benefits, cash and medical benefits, after a storm knocked power out to more than 2,500 homes. Ferry County officials and Colville Tribes requested assistance from the state, after a Friday storm that downed trees, power lines and phone lines, and killed one person at a campground, according to a DSHS news release. Most of the county will be dealing with the effects of power outages for next few days. The Washington State Emergency Management Division will assist the area, as well as the Red Cross, which established a command center in the Keller Community Center. The mobile offices have trained eligibility specialists who can accept and process applications for benefits, conduct eligibility interviews, verify eligibility factors, process changes to current recipients benefits, authorize benefits to approved households, and issue EBT cards, frequently on the very same day.
