Returning to the bill, the role of the Environmental Protection Authority, the EPA, is to, obviously, consider applications for the use of individual hazardous substances, assess them, identify their hazardous properties, set conditions of their use if they approve them, and also provide guidance. And they can reassess chemicals which are already approved for use and see whether the existing controls are fit for purpose. So this bill is part of a programme of work by the EPA and the Ministry for the Environment to modernise how hazardous substances are regulated. In progress there's work on shifting the whole classification system for hazardous substances to the Globally Harmonized System of Classification and Labelling of Chemicals, the GHS system, and developing a new database to support it. That was due to be finished by the middle of this year. I haven't seen anything in the press release section of the EPA's website, but I hope that work is well under way. That's an internationally agreed system, and we are bound to implement it by being a member of the OECD.
