Mercury and mercury compounds
WA category D120; load type and road-transport rules decide whether a tracking form follows.
ComplyOnSiteIs WA D120 hazardous waste?
Not from the code alone. D120 is a WA controlled-waste category. Regulation 3 takes in industrial, commercial, medical, laboratory and sewage-treatment waste and leaves out domestic waste. It also excludes waste that a Class I, II or III landfill can lawfully accept, with set exceptions that include asbestos, tyres and clinical waste.
Where WA road tracking applies, enter D120 in the controlled-waste category field on the DWER tracking form. DWER issues the number. The authorised carrier or driver records collection and transport, and the receiving facility closes the record. Record the holder, amount, containment and destination. The WA load thresholds and exclusions still apply.
What does WA D120 cover?
Elemental mercury and mercury compounds. The category takes the element as well as its compounds, and isn't limited to one named compound or process.
