Regulation 3 updates references in regulation 1 of the Principal Regulations to the current editions of the approved classification and labelling guide and the approved supply list under the Chemicals (Hazard Information and Packaging for Supply) Regulations 1994. Regulation 5 amends regulation 7 of the Principal Regulations so that for a second and subsequent consignments in a succession of consignments of special waste the code identifying the first consignment in that succession must be entered on the consignment note in addition to the relevant code for the consignment in question. Other amendments deal with consignment rounds and identification codes. Regulation 8 inserts a new regulation 10A. Regulation 10A provides that a new consignment note must be prepared where a consignment is rejected by the consignee and is redirected to premises other than those from which they were collected or where they had been produced and sets out the procedure to be followed for the new consignment note.
