Overview of Pipeline Gas Quality and Contract Clauses

摘要

The first edition of AGA Report No. 4A was dated August 1971. By the 1990s, technology had changed so much and deregulation had so revolutionized the business environment that the Transmission Measurement Committee felt compelled to overhaul this document. The effort to revise the document has resulted in a new report that follows somewhat the original organization of the 1971 report, but incorporates recent technology and terminology with updated contract language.
