These Regulations revoke the Submarine Pipe-lines (Electricity Generating Stations) Regulations 1981 (“the 1981 Regulations”). The 1981 Regulations were originally made under section 31(3) of the Petroleum and Submarine Pipe-lines Act 1975 (“the 1975 Act”). However the 1975 Act was repealed in its entirety by the Petroleum Act 1998 (“the 1998 Act”), which is a consolidation Act.
