There are 150,000 hazardous substances that the EPA are administering. That's a significant number and they do require reassessments quite frequently. I've seen that through ag chemicals that I've used in the past, and I know that for very good reasons they do have to come up, new evidence comes into the realm, and we do need to go through that and in our own environment. I note that the Minister said there will be a provision here for temporary changes to the regulations for using those particular chemicals, or may be used in that period while that reassessment is being carried out. I think that's a very sensible change.
