It was issued by the Standards Council on July 29, 2005, with an effective date ofAugust 18, 2005, and supersedesallpreviouseditions. This edition of NFPA 59A was approved as an American National Standard on August 18, 2005. Origin and Development of NFPA59A A committee of the American Gas Association began work on a standard for liquefied natural gas circa 1960. In the autumn of1964, a draft was submitted to the NFPAwith the request that it be considered as the basis for an NFPA standard. The Sectional Committee on Uility Gas prepared a standard that was adopted tentatively at the 1966 NFPA Annual Meeting at the recommendation oftheCormmitteeonGases With the formation of the Committee on Fuel Gases in the summer of 1966, this standard Wwas assigned to that committee and its Subcommittee on Utility Gas Plants. The first official edition was adopted at the 1967 NFPA Annual Meeting under the sponsorship of the Commit- tee on Fuel Gases. By early 1969, it was apparent that the use ofLNG was expanding considerably beyond the utility gas plant applications covered by the 1967 edition. The American Petroleum Institute suggested'that-its standard PUBL 25i0A, Design and Construction of Liquefied Petroleum Gas (ZPG) Installations, be used to help develop a standard having a broader scope. The Commit- tee on Liquefied Natural Gas was established for this purpose. The 1971 edition was the first edition developed under the broadened scope. Subsequent editions were adopted in 1972, 1975,1979,1985,1990,1994,1996,and 2001. The 2006 edition includes revisions in compliance with the Manual of Style for NFPA Techni- cal Commitee Docunents, such as providing only administrative requirements in Chapter 1, referenced publications in Chapter 2, definitions in Chapter 3, and general requirements in Chapter 4. Former Chapters 2 through 11 have been renumbered as Chapters 5 through 14. In addition, editorial revisions were made to make the text more clear. Chapter 5 has been revised to cover double and full containment LNG storage containers. Definitions of these types of containers have also been added to the standard. Seismic design criteria for LNG containers have been revised to correlate with the requirements of ASCE 7, Minimum Design Loads for Buildings and Other Structures. Chapter ll has been revised to add requirements for a contingency plan for potential LNG marine transfer incidents. 59A-2 PRODUCTION,STORAGE,ANDHANDLINGOFLIQUEFIEDNATURALGAS(LNG) Technical Committee on Liquefied Natural Gas RichardAHoffmann, Chair Hoffmann&Feige, NY[SE] TheodoreC.Lemoff,Secretary (Staff-Nonvoting) National Fire Protection Association,MA Donald Barber, Enmat Intemational (UK),United James P.
