Conflicts and open questions

  • DEP's tracker lists the campus twice: one entry marked 'DEP Review Complete' and a later entry with applications pending.
  • The Times Leader (Aug. 22, 2026) reported the campus could eventually hold up to 20 data centers on about 1,200 acres; that figure comes from a developer presentation.
