The much anticipated Water Environment (Oil Storage) (Scotland) Regulations SSI 2006/133 were published on 10 March and came into force on 1 April 2006. Their aim is to require everyone in custody or control of oil to carry out certain works and take the necessary precautions in order to prevent the pollution of the water environment. Like their English equivalent which came into force in 2002, the Regulations apply where more than 200 litres of oil are stored above ground at industrial, commercial or institutional sites. Provisions are made for their storage in impermeable containers, which must be bunded to 110% of the containers storage capacity. Anything attached to the container must be within the bund and any pipes fitted with a drip tray to catch any oil spilled.
