The U.S. Small Business Administration is offering low-interest federal disaster loans for working capital to small businesses economically impacted by the Microwave Tower Fire that occurred in late July and early August.  SBA Administrator Isabel Casillas Guzman made the announcement Tuesday, noting the SBA acted under its own authority to declare a disaster following a request received from Gov. Tina Kotek on Monday.  The disaster declaration makes SBA assistance available in Hood River, Wasco, Sherman, Gilliam, Wheeler, Jefferson, Clackamas, and Marion counties in Oregon, and Klickitat County in Washington.  Small nonfarm businesses, small agricultural cooperatives, small businesses engaged in aquaculture and most private nonprofit organizations of any size may qualify for Economic Injury Disaster Loans of up to $2 million to help meet financial obligations and operating expenses which could have been met had the disaster not occurred.  The SBA virtual recovery center is open weekdays from 8 a.m. to 4:30 p.m. by emailing FOCWAssistance@sba.gov or calling 916-735-1712.
