When the extent of a site’s contamination is such that it is not possible for on-site and off-site treatments to clean up contaminated soil, the waste generator is allowed to remove contaminated soil for appropriate soil disposal in a facility licensed to receive the type of waste involved.Waste classification is essential to determine the method of transportation, licensing requirements of the transporter and the appropriate waste disposal area. It is the waste generator’s primary responsibility to assess and classify wastes properly, use a licensed transporter and to ensure that the wastes are taken to suitable mobile waste processors or waste facilities. Soil needs to be classified depending on the additional contaminants contained within its material. Classifications of waste include: General solid waste (putrescible)Solid waste that has been pre-classified as putrescible are:• household waste that contains putrescible organics• waste from litter bins collected by or on behalf of local councils• manure and night soil• disposable nappies, incontinence pads or sanitary napkins• food waste• animal waste• left over grit and screened material from the sewage treatment process• any mixture of the wastes mentionedGeneral solid waste (non putrescible)These are typically wastes that do not readily decay under standard conditions, emit offensive odours and do not attract vermin or other vectors such as flies, birds and rodents. Some wastes pre-classified as non putrescible are glass, plastic, rubber, ceramics, bricks, cement or metal materials, soils, timber, garden trimmings, agricultural, forestry and crop materials, as well as natural fibrous organic and vegetative materials.Restricted solid wasteConsidered as the highest classification of solid waste, restricted solid waste may only be determined through a chemical assessment where TCLP and SCC levels are measured and compared against threshold values for this type of waste.Other Waste Classifications Include· Hazardous Waste: Coal tar, or pitch waste, lead-acid or nickel-cadmium batteries, lead paint waste.· Liquid Waste: A solid is considered to be a liquid waste when: 1) has an angle of repose of less than 5 degrees above horizontal, or 2) becomes free flowing at or before 60 degrees Celsius or when it is transported, or 3) generally is not capable of being picked up by a spade or shovel. E.g. Acidic solutions or acids in solid form, solvents, waste mineral oils, waste oil, hydrocarbon mixtures sewage sludge and residues, inert, sludges and slurries· Special Waste: Refers to a class of unique waste which includes clinical waste, asbestos waste, cytotoxic waste (toxic to cell production), pharmaceutical, drug or medicine waste, sharp waste (syringes etc) and waste tyres. Once contaminated soil waste has been classified it requires covered transport and disposal to an appropriate waste disposal facility. It must be taken to a facility which is licensed to take that particular classification of soil waste. In addition some waste soils present a high risk to the environment and community. This type of soil requires tracking, especially when being transported over state bordersAll soil tests, classification documents, transport documentation and weight bridge receipts must be kept if questions arise regarding the disposal of the contaminated soil.
