The Merchant Shipping (Prevention of Pollution) (Limits) Regulations 1996
These Regulations define the limits of the zone beyond the territorial sea around the United Kingdom and the Isle of Man in which jurisdiction is exercisable in order to prevent pollution by discharges from ships. The limits follow agreed maritime boundaries with Norway, Denmark, Germany, Netherlands, Belgium, France and the Republic of Ireland. To the west of Scotland, the limits are arcs of 200 n.m. measured from St. Kilda. Towards the Faroes, the limits coincide with the current outer limits of the the Designated Area of the UK continental shelf, pending the establishment of an agreed boundary with Denmark (Faroes).
