Regulatory / Filing History
Maple Creek Energy II LLC filed its Verified Petition for declination of IURC jurisdiction on December 19, 2025. The OUCC filed its recommendation on April 14, 2026. The petitioner submitted a proposed order on April 2, 2026. The IURC’s weekly order list for April 22, 2026 did not include Cause No. 46344, confirming the final order remained pending as of that date.
Key Regulatory Dispute: Decommissioning Financial Assurance
The OUCC recommended the Commission retain jurisdiction specifically over decommissioning financial assurance requirements, noting the absence of a Sullivan County zoning ordinance mandating decommissioning security.
The petitioner argued no decommissioning security was required — consistent with how Phase 1 was treated — and that Sullivan County has no local ordinance mandating it.
This dispute tracks a broader pattern in recent Sullivan County IURC proceedings (see also Sycamore Riverside, Cause No. 46295) where the OUCC has pushed for decommissioning financial assurance in the absence of local zoning requirements.
