SUPPLEMENTARY INFORMATION: 
    PHMSA received a special permit request from the Alaska Gasline 
Development Corporation (AGDC) to deviate from the PSRs in 49 CFR 
193.2167 and 193.2173 in order to use pipe-in-pipe (PIP) technology at 
various segments of their proposed liquefied natural gas (LNG) product 
and LNG quench lines.
    AGDC is proposing to construct, own, and operate one integrated 
natural gas pipeline with gas pre-treatment facilities, interdependent 
interconnection gas delivery points, and a liquefaction and marine 
export facility, (collectively known as the Alaska LNG Project) for the 
purpose of liquefying supplies of natural gas from Alaska. Gas would be 
supplied from the Point Thomson Unit and Prudhoe Bay Unit production 
fields on the North Slope, and provide opportunities for in-state 
deliveries of natural gas and export of LNG in foreign commerce. PHMSA 
has prescribed the minimum PSRs for LNG facilities in compliance with 
49 U.S.C. 60101 et. seq. Those standards are codified in 49 CFR part 
193 and apply to the siting, design, construction, operation, 
maintenance, and security of LNG facilities.
    The Alaska LNG Terminal would include LNG rundown lines, which 
would transfer LNG from the liquefaction units to the LNG storage 
tanks. These lines would be constructed using PIP technology, which 
would be designed to contain releases from the inner pipe within an 
enclosed secondary outer pipe. The three 20-inch diameter PIP rundown 
lines would start at the outlet line of each liquefaction train and 
combine to a 30-inch diameter rundown header, which transfers LNG to 
the storage tanks. The 30-inch diameter PIP rundown header transitions 
to conventional stainless steel piping in the LNG storage tank area 
before branching to two (2) tank loading lines. Additionally, AGDC 
proposes to use PIP technology for four (4) LNG quench lines (two (2) 
supply and two (2) return lines) that would be used to cool down the 
boil-off gas. Four-inch (4-inch) diameter quench lines would be 
connected to the dual 28-inch diameter LNG marine cargo transfer lines 
using fabricated PIP tees. The quench lines would continue to the 
northern edge of the boil-off gas compressor unit spill collection area 
where the PIP transitions to conventional stainless steel piping near 
the boil-off gas compressors.
    The request, proposed special permit with conditions, and Draft 
Environmental Assessment (DEA) for the AGDC LNG Terminal pipeline are 
available for review and public comment in the Docket No. PHMSA-2017-
0157. We invite interested persons to review and submit comments on the 
special permit request and DEA in the docket. Please include any 
comments on potential safety and environmental impacts that may result 
if the special permit is granted. Comments may include relevant data.

    Before issuing a decision on the special permit request, PHMSA will 
evaluate all comments received on or before the comment closing date. 
Comments received after the closing date will be evaluated if it is 
possible to do so without incurring additional expense or delay. PHMSA 
will consider each relevant comment we receive in making our decision 
to grant or deny this request.

     Issued in Washington, DC on December 4, 2019, under authority 
delegated in 49 CFR 1.97.
