Liquefied Natural Gas Regulations; Miscellaneous Amendments

Confirmation of effective date; and partial removal of direct final rule.

This document confirms the effective date of the amendments of the direct final rule which updated the Liquefied Natural Gas (LNG) regulations by replacing the current ``Flammable vapor-gas dispersion protection'' method with a method based on the ``dense gas dispersion (DEGADIS)'' model, and replacing the current ``Thermal radiation protection'' method with a method based on the ``LNGFIRE'' program model. This document removes the section of the direct final rule that incorporated safety requirements for mobile and temporary LNG facilities by referencing National Fire Protection Association (NFPA) Standard 59A (1996 edition), Standard for the Production, Storage and Handling of Liquefied Natural Gas (LNG).
