I thank you for that answer, Minister, and I'm not going to talk about the 50 mph extension, which is causing chaos, but I will talk about Tata Steel and the issues relating to that. We all understand that heavy industry has a consequence of some form of pollution, but many, many, many constituents have expressed huge concern over the levels of fallout that we've had in Port Talbot over the last few months. I appreciate that the warm weather is a contributing factor, we understand that, but this has gone beyond that, before that happened. And what is it doing? Because Natural Resources Wales have responsibility for monitoring and taking action to ensure that the air quality from the works is improved. Can you assure me that they are actually doing that job because residents are going out, not daily, but basically hourly to clean their tables and cars and their windowsills because of the fallout from the works?
