SUPPLEMENTARY INFORMATION: PHMSA received a special permit request from
Argent LNG on March 9, 2026, seeking to waive certain requirements in
the Federal pipeline safety regulations that would otherwise apply to
the design, construction, and testing of proposed LNG storage tanks in
Lafourche Parish, Louisiana.
Argent LNG is proposing to construct and operate gas treatment,
liquefaction, LNG storage, and marine facilities (collectively known as
the Argent LNG Project or the Project) for the purpose of liquefying
domestic natural gas for export to foreign markets. The proposed
membrane tanks, to be used for LNG storage, will have a nominal working
volume of 220,000 cubic meters or 1,383,756 barrels. Argent 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, ``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. Argent LNG is applying for a special permit to
authorize the design, construction, and testing of membrane containment
tank systems (membrane tanks) in accordance with the 2026 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 Argent LNG's request are available for review and public
comment in Docket No. PHMSA-2026-0959. 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, or 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
[[Page 25755]]
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, under authority delegated in 49 CFR
1.97.
Linda Daugherty,
Acting Associate Administrator for Pipeline Safety.
