There have been some incidents at the Shell and ICI plants at Runcorn, but, in all fairness, the hon. Gentleman should point out the huge size of the plants and the complicated processes that take place there. The new regulatory regime which has come into force in this country, which is operated by Her Majesty's inspectorate of pollution—integrated pollution control—is revolutionary. It is the first of its kind in Europe and the HMIP is looking into all aspects of the processes operated on Merseyside. They will all come under integrated pollution control. The hon. Gentleman will see that, in time, it will have considerable benefits for all people on Merseyside.
