Louisiana agency seeks comment on air permit for two new Cameron LNG trains

The Louisiana Department of Environmental Quality is taking comments until Feb. 18 on a draft permit modification that would cover two new liquefied natural gas (LNG) trains at the Cameron LNG LLC facility located in Cameron Parish.

Cameron LNG requested a PSD and a Part 70 Air Operating Permit Modification to construct and operate two additional natural gas liquefaction trains (Trains 4 and 5) which will be similar to three previously proposed trains. Proposed equipment will include four refrigeration compressor turbines, three generators, three water pumps, two thermal oxidizers, two diesel tanks, a condensate tank, and a flare. This application was processed as an expedited permit. 

Train 4 and Train 5 will be similar to the previously proposed Trains 1, 2, and 3. All five trains are considered as parts of the same project. PSD applicability and preliminary model screening were re-evaluated using total emissions from all five trains. No new PSD pollutants will be triggered. BACT for the previously proposed equipment is still valid and will not be re-evaluated. Neither the project nor the general commercial, residential, industrial, or other growth associated with it is expected to have a significant adverse impact on soil, vegetation, visibility, or air quality in the area of the facility or any Class I area. 

If LDEQ finds a significant degree of public interest, a public hearing will be held.

Cameron LNG applied in September 2015 to the Federal Energy Regulatory Commission for authority to site, construct, and operate facilities to provide additional natural gas processing, storage, and liquefaction capability at the site of the existing Cameron LNG liquefied natural gas terminal. The expansion project would increase the Cameron LNG terminal’s maximum natural gas liquefaction and export capabilities from 14.95 to 24.92 million tonnes per annum (MPTA).

The construction and operation of these facilities is collectively referred to as the “Cameron LNG Expansion Project.” In 2003, the commission issued to Cameron LNG (formerly Hackberry LNG) authorization to site, construct and operate an LNG import facility. The initial maximum send-out rate for the LNG Terminal was 1.5 Billion cubic feet (Bcf) per day.

In 2007, the commission issued another authorization that increased the LNG Terminal’s maximum send-out rate to 1.8 Bcf per day. Cameron LNG completed construction and testing of the LNG Terminal and placed it in service in July 2009. The LNG Terminal has been in continuous operation since that time. Initially, the LNG Terminal was used for the sole purpose of receiving and storing foreign-sourced LNG, and re-gasifying such LNG and sending natural gas out for delivery to domestic markets.

In 2011, the commission authorized Cameron LNG to operate the LNG Terminal for the additional purpose of exporting previously imported (i.e., foreign-sourced) LNG on behalf of its customers. The LNG Terminal has an existing interconnection with Cameron Interstate Pipeline LLC.

In June 2014 the commission authorized Cameron LNG’s “Liquefaction Project” under Section 3 of the Natural Gas Act. This authorization included natural gas processing, liquefaction and storage facilities at the LNG Terminal. These facilities included a fourth LNG storage tank and three liquefaction trains (Trains 1, 2, & 3) including the associated natural gas pre-treatment equipment, to produce up to 14.95 million metric tonnes per annum (MTPA) of LNG for export. The Liquefaction Project is currently under construction.

In the September 2015 application, Cameron LNG proposes to add additional storage and liquefaction facilities to the ongoing Liquefaction Project. The Expansion Project will include two additional liquefaction trains (Trains 4 and 5) each with a maximum LNG production capacity of 4.985 MTPA (9.97 MTPA total), and the associated natural gas pre-treatment facilities.

Cameron LNG is indirectly owned by affiliates of Sempra EnergyMitsui & Co. Ltd., Mitsubishi Corp. (through a related company jointly established with Nippon Yusen Kabushiki Kaisha), and Engie S.A., formerly GDF SUEZ S.A.
