A zone extending beyond the territorial sea around the UK and the Isle of Man in which jurisdiction is exercisable by the UK Government (in accordance with UNCLOS) for preventing pollution.
Under The Merchant Shipping (Prevention of Pollution) (Limits) Regulations 1996, as amended, it extends to 200 miles from baselines or to the nearest median line (i. e. the agreed boundary with a neighbouring State’s waters). The zone is sometimes referred to as “UK controlled waters”.
