Western Australia D140: this constituent entry covers both hexavalent and trivalent chromium compounds.
ComplyOnSiteIs WA D140 hazardous waste?
Not from the code alone. D140 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 D140 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 D140 cover?
Chromium compounds, in both trivalent and hexavalent forms. The category is the chemical group and isn't limited to one named compound or production process.
