ADEC preliminarily approves Hilcorp Platform C air permit in Cook Inlet

The Alaska Department of Environmental Conservation has made a preliminary decision to approve Hilcorp Alaska's application for an Air Quality Control Operating Permit for Platform C in Cook Inlet, designated AQ0085TVP05. The preliminary decision opens a public comment and appeal process, which is the key next step before any final action on the permit.

The preliminary decision is not a final approval. Pollutant limits, comment deadlines, and any hearing schedule should be verified in the full permit documents posted at ADEC's public notices portal. The full permit conditions are not visible in the surfaced notice, so the practical environmental impact cannot be assessed from the notice text alone.

Parallel Proceedings for Cook Inlet Facilities

The Platform C action is part of a broader, ongoing permitting track. ADEC has published similar preliminary approvals for other Hilcorp offshore facilities in Cook Inlet, indicating a recurring regulatory cycle rather than an isolated action. A separate notice of application for State Air Quality Permit AQ0060TVP05 has also been posted for a Hilcorp facility, and ADEC has advanced a preliminary approval for the Monopod Platform under permit AQ0067TVP04. Specific pollutant caps for Platform C were not disclosed in the surfaced notice and should be obtained directly from ADEC's posted permit documents.

How to Comment

The public comment and appeal process is now open. Interested parties should consult the full notice posted at ADEC's public notices portal for submission instructions, deadlines, and any hearing procedures.
