FERC issue draft environmental impact statement for Texas LNG
Published by Will Owen,
The staff of the Federal Energy Regulatory Commission (FERC) have prepared a draft environmental impact statement for the Texas LNG project proposed by Texas LNG Brownsville, LLC.
Texas LNG requests authorisation under Section 3(a) of the Natural Gas Act and Part 153 of the Commission’s regulations to site, construct and operate a LNG terminal to liquefy and export natural gas at a proposed site on the Brownsville Ship Channel in Cameron County, Texas. The project consists of the following facilities:
- Gas gate station and interconnect facility.
- Pretreatment facility.
- Open art turbo-expander for pentane plus heavy carbon removal.
- A liquefaction plant consisting of two liquefaction trains and ancillary support facilities.
- Two approximately 210 000 m3 above-ground full containment LNG storage tanks with cryogenic pipeline connections to the liquefaction plant and berthing dock.
- An LNG carrier berthing dock capable of receiving LNG carriers between approximately 130 000 m3 and 180 000 m3 in capacity.
- A permanent material offloading facility to allow waterborne deliveries of equipment and materials during construction and mooring of tug boats while an LNG carrier is at the berth.
- Thermal oxidiser, warm wet flare, cold dry flare, spare flare, acid gas flare and marine flare.
- Administration, control, maintenance and warehouse buildings and related parking lots.
- Electrical transmission line and substation, water pipeline, septic system and stormwater facilities/outfalls.
Natural gas would be delivered to the Texas LNG project site via a non-jurisdictional intrastate, 30 in. diameter natural gas pipeline that would be constructed, owned and operated by a third party, separate from Texas LNG.

The EIS has been prepared in compliance with the requirements of the National Environmental Policy Act (NEPA), the Council on Environmental Quality regulations for implementing NEPA in Title 40 Code of Federal Regulations, Parts 1500–1508 (40 CFR 1500-1508) and FERC regulations implementing NEPA (18 CFR 380).
The conclusions and recommendations presented in the EIS are those of the FERC environmental staff. Input from the US Army Corps of Engineers, US Coast Guard, US Department of Energy, US Department of Transportation’s (DOT) Pipeline and Hazardous Materials Safety Administration, the DOT’s Federal Aviation Administration, the US Fish and Wildlife Service (FWS), the National Park Service, the US Environmental Protection Agency and the National Oceanic and Atmospheric Administration – National Marine Fisheries Service (NMFS), as cooperating agencies, was considered during the development of our conclusions and recommendations; however, these agencies could develop their own conclusions and recommendations and would adopt the final EIS per 40 CFR 1506.3 (where applicable) if, after an independent review of the document, they conclude that their permitting requirements have been satisfied.
The FERC determined that the construction and operation of the Texas LNG Project would result in adverse environmental impacts. However, the impacts on the environment from the proposed Project would be reduced to less than significant levels with the implementation of Texas LNG’s proposed impact avoidance, minimisation and mitigation measures and the additional measures recommended by FERC staff, with the exception of impacts on visual resources which would be significant when viewed from the Laguna Atascosa NWR. The Commission based its conclusions upon information provided by Texas LNG and through data requests; field investigations; literature research; geospatial analysis; alternatives analysis; public comments and scoping sessions; and coordination with federal, state and local agencies and Native American tribes. The following factors were also considered in its conclusions:
- The LNG terminal would be constructed in an area currently zoned for commercial and industrial use, along an existing, man-made ship channel.
- Texas LNG would follow its Spill Prevention and Response Plan (construction), Spill Prevention Control and Countermeasures Plan (operation), Stormwater Pollution Prevention Plan, Noxious Weed and Invasive Plant Plan, Facility Lighting Plan, Migratory Bird Plan, Terrestrial Reptile and Amphibian Conservation Plan, Unanticipated Discovery Plan for cultural resources and Fugitive Dust Control Plan.
- The US Coast Guard issued a Letter of Recommendation indicating that the Brownsville Ship Channel would be considered suitable for the LNG marine traffic associated with the Project.
- The US Department of Transportation has no objection to Texas LNG’s methodology to comply with the 49 CFR 193 siting requirements for the LNG terminal.
- All appropriate consultations with the FWS and NMFS regarding federally listed threatened and endangered species would be completed before construction is allowed to start.
- All appropriate National Historic Preservation Act consultations with the Texas State Historic Preservation Office and Advisory Council on Historic Preservation would be completed before construction is allowed to start in any given area.
- Texas LNG would implement its Project-specific Environmental Construction Plan, which incorporates our Upland Erosion Control, Revegetation and Maintenance Plan and Wetland and Waterbody Construction and Mitigation Procedures, to minimise impacts on soils, wetlands and waterbodies.
- The FERC’s environmental and engineering inspection and mitigation monitoring program for this Project would ensure compliance with all mitigation measures and conditions of any FERC authorisation.
The draft EIS comment period closes on 17 December 2018. The FERC Commissioners will take into consideration staff’s recommendations when they make a decision on the project.
