Summary of Modification
This Modification looks to provide an update to the NExA tables, and some of the language used around the AQ Review process to provide greater clarity. This will be achieved by adding relevant dates to the NExA tables to provide time periods for which they are relevant, with further clarity added for when the document is ‘live’ or ‘proposed’.
