The Oil in Navigable Waters (Heavy Diesel Oil) Regulations 1967
These Regulations, which come into force on 18th May 1967 define heavy, diesel oil for the purposes of section 1 of the Oil in Navigable Waters Act 1955. This definition replaces that in the Oil in Navigable Waters (Heavy Diesel Oil) Regulations 1956 (S.I. 1956/897) which are revoked. The only change is the substitution in the definition of reference to a 1966 Standard Method of test in place of the Standard Method of 1954 specified in the 1956 Regulations.
