A proposed 2-million-square-foot AI data center at the former Cleveland-Cliffs steel mill in Plymouth Township, near Conshohocken, was abruptly withdrawn during a recent zoning board hearing after legal issues arose over the applicant’s standing. Developer Brian O’Neill’s attorney, Edmund Campbell, sought a continuance to the December meeting, but Cleveland-Cliffs attorney Heather Fine noted that no finalized agreement of sale existed, leaving the developer without authority to proceed. Hundreds of residents, who had rallied against the project due to concerns about noise, pollution and energy use, had packed the hearing. While O’Neill cited potential economic benefits and the property’s industrial zoning as justification, the application was officially withdrawn. Township officials said that if the applicant chooses to refile, the matter will not be revisited until at least the new year. Parties involved will also have an opportunity to appeal the decision once it is issued.
