Background

Venture Global CP2 LNG and Venture Global CP Express sought Federal Energy Regulatory Commission approval to construct and operate an LNG export terminal on Louisiana’s Calcasieu Ship Channel and an 85-mile natural-gas pipeline from East Texas to the terminal. After preparing an environmental impact statement and a supplemental environmental impact statement, FERC authorized the terminal under Section 3 of the Natural Gas Act and found the pipeline required by public convenience and necessity under Section 7.

Individuals and advocacy groups petitioned for review of FERC’s authorization and rehearing orders. They argued that FERC misinterpreted and misapplied the Natural Gas Act and inadequately analyzed air pollution, greenhouse-gas emissions, cumulative environmental effects, and harm to the commercial fishing industry under the National Environmental Policy Act.

The Court’s Holding

The D.C. Circuit denied the petitions for review. It held that Section 3 creates a presumption favoring authorization of an LNG terminal and does not require FERC to begin from equipoise or prove that a terminal’s benefits outweigh its harms. Petitioners instead had to affirmatively show that the terminal would be inconsistent with the public interest, and FERC reasonably concluded that they had not done so. The court also upheld the pipeline authorization, ruling that FERC could rely on the affiliates’ precedent agreement absent evidence of self-dealing and had reasonably explained why the pipeline’s benefits outweighed its adverse effects.

The court also rejected the NEPA challenges. FERC reasonably used updated emissions data, omitted emissions sources it found speculative or insufficiently supported, relied on national ambient air quality standards instead of the proposed COBRA screening tool, and adequately explained why the Moss Lake Compressor Station’s emissions did not warrant further cumulative-effects modeling. FERC also took the required hard look at potential temporary and long-term effects on commercial fishing and reasonably found those effects moderate but not significant after considering mitigation and the continued availability of fishing waters.

Key Takeaways

  • Natural Gas Act Section 3 presumes approval of an LNG terminal unless opponents affirmatively demonstrate that authorization would be inconsistent with the public interest; it does not impose an ordinary benefits-versus-harms balancing test on FERC.
  • FERC generally may establish market need for a pipeline through a precedent agreement between affiliates when there is no plausible evidence of self-dealing or affiliate abuse.
  • Applying the substantial deference required in NEPA cases, the court upheld FERC’s technical choices concerning emissions inventories, cumulative-effects modeling, air-quality benchmarks, and impacts on commercial fishing.

Why It Matters

The decision reinforces FERC’s broad discretion when reviewing LNG facilities and pipelines and underscores the demanding burden challengers face under both the Natural Gas Act and NEPA. It also confirms that courts will generally defer to adequately explained agency judgments about the scope, methodology, and significance of environmental analysis.

For project opponents, the opinion highlights the importance of presenting specific objections during agency rehearing and supporting challenges to affiliate precedent agreements with plausible evidence of self-dealing. For developers, it confirms that updated state emissions data, established federal air-quality standards, and concrete mitigation measures can support FERC approvals when the agency clearly explains its reasoning.
