delete Primary Industries Levies and Charges (National Residue Survey Levies) Amendment Regulations 1999 (No. 4)
This 1999 amendment adjusted levy rates for the National Residue Survey, a program that monitors residues in agricultural products. It likely modified the amounts payable by producers and the collection procedures.
As an amendment from 1999, its operative provisions have almost certainly been superseded by later instruments or have become spent. Retaining obsolete regulatory texts creates legal uncertainty and unnecessary compliance costs for businesses and administrators. Removing it would streamline the statute book without affecting any substantive obligations, which are now governed by current instruments.
