Puget Sound Energy - LNG Facility Tacoma

Puget Sound Energy submitted an application for a new liquefied natural gas (LNG) facility in the Tacoma Tide Flats. The site would include a new Total Ocean Trailer Express Marine Vessel LNG fueling system used to distribute to ships.  Other potential uses for the LNG product were also identified, primarily marine fuel.  

On March 29, 2019, the Agency published the Final SEIS (FSEIS) for this GHG analysis, The FSEIS documents include the review and consideration of the comments received. The publication of the FSEIS represents the completion of this part of the review process and will be used to support the review of the air permit application. For more information and to view the FSEIS documents, visit the SEIS tab below. Schedule information regarding the air permit review status and processes are not presently available. 

On July 22, 2019 the Agency completed a review of the Puget Sound Energy Tacoma Liquefied Natural Gas (LNG) facility Notice of Construction Application (NOC 11386) and has made a preliminary determination that the proposal meets all the requirements of Agency Regulations I, II and III and should be approved. The Agency will hold a public comment period and public hearing on a proposed permit. The notice for this proposed permit comment and hearing process may be found below and permit review documents and supporting information may be found on the Application Documents tab.

Notice of Public Hearing and Comment Period

Puget Sound Clean Air Agency

Proposed Order of Approval No. 11386

Puget Sound Energy 

1001 E Alexander Ave. 

Tacoma WA  98421

The Puget Sound Clean Air Agency will hold a public comment period and public hearing on a proposed permit for Puget Sound Energy – Tacoma Liquefied Natural Gas (LNG) Plant.

The emissions associated with this project were evaluated and could total up to 49 tons per year of Volatile Organic Compounds (VOCs), 9.1 tons per year of Sulfur Dioxides (SO2), 1.2 tons per year of Particulate Matter (PM), 3.8 tons per year of Nitrogen Oxides (NOx), 12 tons per year of Carbon Monoxide (CO), 0.37 tons per year of Hazardous Air Pollutants (HAPs), and 1.03 tons per year of Toxic Air Contaminants (TACs, excluding criteria pollutants identified above).

Preliminary Determination

The Agency has completed a review of PSE’s Tacoma LNG application No. 11386 and has made a preliminary determination that the proposal meets all the requirements of Agency Regulations I, II and III and should be approved. A review of the environmental impacts from this project was evaluated by the City of Tacoma, as documented in an Environmental Impact Statement (EIS) published on November 9, 2015. The Puget Sound Clean Air Agency supplemented the Air and Cumulative Impact sections in the City of Tacoma’s FEIS, specifically related to the life-cycle emission of greenhouse gases (GHGs), with a published FSEIS on March 29, 2019. The Agency is relying on both documents to satisfy the SEPA requirements for this NOC application. More information on the EIS and the SEIS can be found on this page.
