SUPPLEMENTARY INFORMATION: PHMSA received a special permit request from
Gulfstream LNG on September 17, 2025, seeking to waive certain
requirements in the Federal pipeline safety regulations that would
apply otherwise to the design, construction, and testing of a proposed
LNG storage tank in Plaquemines Parish, Louisiana.
Gulfstream LNG is proposing to construct and operate gas treatment,
liquefaction, LNG storage, truck loading, and marine facilities
(collectively known as the Gulfstream LNG Project or the Project) for
the purpose of liquefying domestic natural gas for export to foreign
markets as LNG. The proposed project would include a membrane tank, to
be used for LNG storage, with a nominal working volume of 200,000 cubic
meters or 1,258,000 barrels. Gulfstream LNG seeks to waive the
requirements of 49 CFR 193.2101(a), 193.2301, and 193.2303, which
incorporate by reference the 2001 edition of National Fire Protection
Association (NFPA) 59A-2001, ``Standard for the Production, Storage,
and Handling of Liquefied Natural Gas (LNG),'' for the design,
construction, and testing of LNG facilities, including the design of
LNG storage tanks. Specifically, Gulfstream LNG is applying for a
special permit to authorize the design and construction of a membrane
containment tank system (membrane tank) in accordance with the 2023
edition of NFPA-59A, which is not incorporated by reference in 49 CFR
part 193.
The special permit request and the proposed special permit
conditions for Gulfstream LNG's request are available for review and
public comment in Docket No. PHMSA-2025-1073. PHMSA invites interested
persons to review and submit comments in the docket on the special
permit request and the proposed special permit conditions. Please
submit comments on any potential safety, environmental, and other
relevant considerations implicated by the special permit request.
Comments may include relevant data.
Before issuing a decision on the special permit request, PHMSA will
evaluate all comments received on or before the closing date. PHMSA
will consider each relevant comment it receives in making its decision
to grant or deny this special permit request.
Issued in Washington, DC, on November 17,2025, under authority
delegated in 49 CFR 1.97.
Linda Daugherty,
Acting Associate Administrator for Pipeline Safety.
