US federal regulators have issued a final environmental impact statement for the proposed Annova liquefaction project in southern Texas in which they reiterated warnings about the project’s potentially significant effects on the environment and protected species in the region, writes Caroline Evans.

Staff from the US Federal Energy Regulatory Commission (Ferc) said the project’s construction would result in the permanent loss of nearly 53 acres of wetlands, though the Annova LNG developers have been working on a mitigation plan that would reduce those impacts to “less than significant levels”.
