ASBG s Comparison of Queensland vs NSW and Victoria s Hazardous Waste Classifications

Transcription

1 ASBG s Comparison of Queensland vs NSW and Victoria s Hazardous Waste Classifications Note the Queensland limits set their levy rates of $35/t, $50/t and $150/t on wastes. Unlike NSW and Victorian limits which can also be linked to levy rates, the Queensland limits do not set landfill acceptance criteria, which are set on a licence by licence basis. Table 1 Pre-classified regulated wastes Regulated waste or constituent Pre-classification Comments Acidic solutions and acids in solid form Regulated Waste - High Hazard Needs a test method to determine what are considered acidic. Perhaps DG corrosive definition. Needs one for solids. Animal effluent and residues, including abattoir effluent, poultry and fish processing waste Regulated Waste Low Hazard Requires a test limit eg BOD limit. Asbestos (if not exempt) Regulated Waste - High Hazard Should be based on the new Assessment of Contaminated Sites NEPM. Basic (alkaline) solutions and bases (alkalis) in Regulated Waste - High Hazard Needs a test method to determine what are considered acidic. solid form Perhaps DG corrosive definition. Needs one for solids. Treated clinical and related waste Regulated Waste Other Needs to be better defined. Food processing waste Regulated Waste Low Hazard Needs to be better defined, does it include bio-solids? Grease trap waste Regulated Waste Low Hazard Needs to be defined. Highly odorous organic chemicals, including mercaptans and acrylates Regulated Waste - High Hazard Needs to be better defined. Material containing polychlorinated biphenyls (PCBs), polychlorinated napthalenes (PCNs), Regulated Waste - High Hazard Appears consistent with PCB national plans in polychlorinated terphenyls (PCTs) or polybrominated biphenyls (PBBs) Note: Concentrated PCBs and liquid scheduled PCBs cannot be disposed to landfill under the Waste Management Regulation Mineral oils Regulated Waste - High Hazard See limits below. Non-toxic salts including, for example, saline Regulated Waste Other Needs to be better defined. effluent Organic solvents, other than halogenated solvents, including, for example, ethanol Regulated Waste - High Hazard Some defined below, but not exhaustive, suggest using the DG classification for flammable liquids and solids + tests below. Defined below. Organohalogen compounds, other than another substance stated in the schedule Regulated Waste - High Hazard Oxidising agents Regulated Waste - High Hazard Suggest using the DG classification for Class 5.1 Oxidizing

2 substances. Perchlorates Regulated Waste - High Hazard Suggest using the DG classification for Class 5.1 Oxidizing substances. Treated Pharmaceuticals, drugs and medicines Regulated Waste Low Hazard Part of clinical wastes? Phosphorous compounds, other than mineral Regulated Waste - High Hazard Suggest DG classifications for Class 4.1, 4.2 and 4.3. Otherwise phosphates captures super phosphate. Polychlorinated dibenzo-furan (any congener) Regulated Waste - High Hazard Refer to national/international definitions and limits Stockholm Convention Polychlorinated dibenzo-p-dioxin (any congener) Regulated Waste - High Hazard Refer to national/international definitions and limits Stockholm Convention. Reactive chemicals Regulated Waste - High Hazard Suggest a DG classification classes 4, 5, and 8. Reducing agents Regulated Waste - High Hazard Suggest a DG classification classes 2.1, 3, 4, and 8. Sewage sludge and residues, including nightsoil Regulated Waste Low Hazard Use bio-solid classifications. and septic tank sludge Surface active agents (surfactants) containing principally organic constituents, whether or not also containing metals and other inorganic materials Regulated Waste - High Hazard These are usually liquids. Requires a test method and ranges for other, low and high hazardous waste categories. Tallow Regulated Waste - High Hazard Tallow is not a hazardous material, so its classification of high hazardous waste is not appropriate. Tellurium and tellurium compounds Regulated Waste Low Hazard Tellurium is more toxic than tallow and vegetable oils, it should be at least high hazardous waste and have appropriate limits set. Triethylamine catalysts for setting foundry sands Regulated Waste - High Hazard Tyres Regulated Waste Low Hazard Higher charges for tyres is due to voidage issues in landfills. Generally tyres are well recycled. Cut or shredded tyres should not attract the hazardous levy. Vegetable oils Regulated Waste - High Hazard Vegetable oils are not hazardous materials, so its classification of high hazardous waste is not appropriate. Waste containing peroxides other than hydrogen Regulated Waste - High Hazard Suggest using the DG classification for Class 5.2 Organic peroxides. peroxide Treated (incinerated) waste from the manufacture or preparation of pharmaceutical products Waste of a explosive nature, other than an explosive within the meaning of the Explosives Act 1999 Regulated Waste Low Hazard Regulated Waste - High Hazard Treated timber Regulated Waste Other Accepted. This criteria is too broad to have meaning. Suggest DG classifications for Class 4.1, 4.2,4.3 and 5.2.as these captures sub Class 1 explosives.

3 Table 2 Regulated waste low hazard Comparison with NSW TCLP1 range, so the lower NSW figures are comparable with Queensland s high hazardous waste For Victorian comparisons the limit for Category B wastes was compared to Queensland s high hazardous waste Most comparisons are on leachate In some cases the total concentration is used, where it is indicated by (total).

But use of a <50 mg/kg/ limit for all chlorinated aliphatic compounds is inconsistent with other states. If applied the limit should be attached to a list of such compounds, such as the list of 5 compounds provided in this section.
