The Vermont developer working with a South Korean bio-technology company to bring 250 jobs to the Newport area says another 250 jobs could come to the area by leasing clean rooms to businesses from around the world. Developer Bill Stenger told members of the Newport City Renaissance Corp. Wednesday he and his partners are working with economists and attorneys to prepare for permitting and construction. The Caledonian Record (http://bit.ly/OHOjtF) reports part of the new AnC Bio Vermont expansion will include an affordable housing complex.
