We are seeking your input on proposed scheduling decisions under the Industrial Chemicals Environmental Management Standard (IChEMS).

IChEMS is a national approach to managing chemical use, storage, handling and disposal. It will deliver nationally consistent environmental standards for managing industrial chemicals and make it easier for industry to choose less harmful chemicals.

Chemicals will be listed on the IChEMS Register in one of seven schedules, as shown in the infographic below, to provide information on their relative environmental risk. The IChEMS Register will also include risk-proportionate controls that should be applied to protect the environment.

The information that you provide on these proposed decisions will inform the regulatory scheduling of chemicals on the IChEMS Register.

An indicative list of chemicals that are covered by the proposed regulatory scheduling decisions is available in the Supporting Documents library. This list contains chemical names and CAS Registry Numbers in a Comma Separated Values (CSV) format to assist chemical users to search their chemical inventories. The list is not comprehensive and should not be relied on to identify all chemicals that may be subject to the proposed regulatory scheduling decisions.

List showing how environmental risks and associated controls for the Industrial Chemicals Environmental Management Standard (IChEMS) Schedules increase from Schedule 1 (not appropriate to list in Schedule 2 to 7 for any use) and Schedule 2 (unlikely to cause harm) through to Schedule 7 (likely to cause serious or irreversible harm).

What happens next

Public consultation on proposed IChEMS regulatory scheduling decisions for the following chemicals is now closed:

  • Hexabromobiphenyl (HBB) - proposed schedule 7
  • Hexachlorobutadiene (HCBD) - proposed schedule 7
  • Polychlorinated naphthalenes (PCN) - proposed schedule 7
  • 13-Oxabicyclo[10.1.0]trideca-4,8-diene, (1R,4E,8Z,12R)-rel- - proposed schedule 3
  • 4-Pentenal, 5-cyclohexyl-2,4-dimethyl-, (4E)- - proposed schedule 3
  • 2-Oxazolidinone, 3-ethenyl-5-methyl- - proposed schedule 2
  • Siloxanes and Silicones, di-Me, hydroxy-terminated, polymers with 3-(trimethoxysilyl)-N-[3-(trimethoxysilyl)propyl]-1-propanamine - proposed schedule 2
  • 2-Propenoic acid, 2-methyl-, butyl ester, polymers with alkyl methacrylate, substituted-methylethyl-terminated hydrogenated polyalkene methacrylate, Me methacrylate and styrene - proposed schedule 1

We will review your submissions and the Minister (or the Ministers delegate) will consider all responses when making the final scheduling decisions.
