The Environment Quality ( Prescribed Premises) (Crude Palm Oil) Regulations 1977 containing the enabling provisions for the stipula­tion of acceptable conditions of effluent discharge in licences was gazetted on 3 November 1977 arid came into force on 1 July 1978. These ac­ceptable conditions were in the form of a four generation set of effluent standards. Since then, the standards have been revised and the existing palm oil mill effluent (POME) standards for water­course discharge are shown in Table 1.
