Quick Reference: Why Sullivan County Is Different

Sullivan County operates without a local comprehensive zoning ordinance for most of its unincorporated townships, including Fairbanks Township. This has been confirmed in multiple IURC filings (Cause Nos. 45539, 46266, 46295, 46344). This means:

  • Projects do not need local zoning approval in most of the county
  • Projects still require IDEM permits, road use agreements, and IURC proceedings
  • The absence of local zoning is why the OUCC has pushed for decommissioning financial assurance as an IURC condition in multiple recent proceedings
