FERC Proposes Blanket LNG Authorizations, Cuts Air Modeling Reviews

US liquefaction projects could win approval for new trains, storage tanks and marine berths after a 90-day notice-and-protest period under rules FERC proposed unanimously on Oct. 15 — a structural change to how export terminals expand on the Gulf Coast and beyond.

The Federal Energy Regulatory Commission put forward two separate measures at the same meeting: a blanket authorization program for eligible LNG plant activities, and a draft policy statement that would stop requiring air-dispersion modeling in the commission's NEPA reviews of pipeline and other projects.

How would the blanket LNG program work?

FERC modeled the framework on its blanket certificate program for interstate natural gas pipelines, which has run for roughly 40 years. The LNG version introduces a three-tier structure.

• Tier 1 — 90-day track. Major construction, including new liquefaction trains, storage tanks and marine berths, following a 90-day notice-and-protest period. Eligible projects can extend beyond an existing plant's footprint but must permanently occupy no more than 25 acres of previously disturbed or developed land or waterways in industrially zoned or unzoned areas. Developers must use the same or upgraded versions of equipment already authorized at the terminal.
• Tier 2 — 60-day track. Projects that increase authorized capacity while staying within the existing footprint and equipment design limits qualify after a 60-day notice period.
• Tier 3 — automatic. Other activities gain automatic authorization, subject to notification and reporting, provided they don't raise authorized capacity, expand the footprint or exceed equipment design limits.

One departure from the pipeline program stands out: the LNG proposal carries no dollar limits on eligible projects. For a basin built on multi-billion-dollar train expansions, that omission matters.

The takeaway: a developer adding a train at an existing terminal could move on a federal clock measured in weeks, not the open-ended case-by-case docket cycle.

What changes in air-quality review?

Under the companion draft policy statement, FERC would stop requiring applicants to submit air-dispersion modeling and would no longer use that modeling in its NEPA reviews of operational air-quality effects from gas pipelines and other projects.

FERC's reasoning is jurisdictional: federal and state regulators already assess air emissions under the Clean Air Act, so the commission would instead rely on applicant and staff information to disclose potential air-quality effects without duplicating those reviews. The change, FERC said, would focus NEPA analyses on matters within the commission's statutory authority.

Whether that division of labor holds under litigation is a separate question — but on paper, it removes one layer of modeling from pipeline applicants' compliance burden. Comments on the draft policy statement are due Nov. 16.

What happened with Louisiana LNG?

At the same meeting, FERC amended Louisiana LNG's permits to add an interconnection and receipt meter station linking the Calcasieu Parish export terminal — now under construction — to the Kinder Morgan Louisiana interstate natural gas pipeline system.

The operator said the interconnection would give the plant an additional gas supply source sooner than some alternatives.

Woodside, the project operator, reported in August that the initial phase stood 28% complete, with three trains and two storage tanks under construction. First LNG remains targeted for 2029.

In plain terms: the terminal's feedgas options just widened while its federal permitting path just got shorter, if the new rules stick.

What's the watch item?

FERC will accept comments on the blanket LNG authorization proposal for 60 days after publication in the Federal Register. The air-quality policy comments close Nov. 16. Watch whether interveners challenge the program's scope — particularly the absence of dollar caps — before it takes effect.
