Gas Industry Co maintains a Gas Quality Requirements and Procedures (Gas Quality R&P) document describing the legal requirements and industry procedures for managing gas quality.
The current version of the document can be found under Related Documents below. Also, in anticipation of the new Gas Transmission Access Code (GTAC) coming into effect on 1 April 2020, we have developed an updated version of the document. The updated document, including our review of industry comment on a draft version can be found here.
The Gas Quality R&P document available below is maintained by Gas Industry Co and is updated from time to time as changes occur and/or new information comes to hand.
