Liquid waste means any waste that:
- has an angle of repose of less than 5 degrees above horizontal, or
- becomes free-flowing at or below 60 degrees Celsius or when it is transported, or
- is generally not capable of being picked up by a spade or shovel.
The EPA may classify additional wastes as liquid waste from time to time by a notice published in the NSW Government Gazette.
All currently gazetted liquid wastes are listed on DECCW’s website at www.environment.nsw.gov.au/waste/wastetypes.htm.
