Under the Biden administration, the transportation department has proposed a suspension of the Trump-era LNG rule allowing the substance to be transported via rail and to replace it with a new rule. The suspension was supposed to be published by June 2022, but it and the new rule have been delayed twice, and are now supposed to be final in March, Ong said.
Still, the US transportation department (DoT) in 2020 approved a rule to allow liquified natural gas, or LNG, to be shipped via rail with no additional safety regulations. Trains can now run 100 or more tank cars filled with 30,000 gallons of the substance, largely from shale fields to saltwater ports.
Just 22 train tank cars filled with LNG hold the same amount of energy as the Hiroshima bomb, a coalition of environmental groups wrote in comments to regulators opposing the LNG rail rule change in 2020. That is raising fears of a catastrophe if a proposed LNG port is built in New Jersey, which could take shipments from two 100-car trains daily that would run through nearby metro Philadelphia.
