Direct final rule.

This direct final rule updates 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. In addition, this final rule incorporates safety requirements for mobile and temporary LNG facilities by referring to the National Fire Protection Association (NFPA) Standard 59A (1996 edition)-- Standard for the Production, Storage and Handling of Liquefied Natural Gas (LNG).
