Developer told WyoFile and the Casper Star-Tribune it will no longer pursue a data center in Natrona or Converse counties; it is still pursuing its Uinta County (Evanston) project
Notes: The $500M proposal first straddled Natrona and Converse counties before moving entirely to rural Natrona County. Talks with Natrona County commissioners began in September about using the state's industrial park exemption instead of a full Industrial Siting Act review, but no permit or zoning application had been filed. County commissioners said they learned of the cancellation from news reports.
