The purpose of the bill is to amend the underlying Hazardous Substances and New Organisms Act 1996 in order to improve the assessment and reassessment of hazardous substances. These substances include the chemicals that are widely used in industry and in agriculture. The main changes being made to the hazardous substances law relate to substances—chemicals—not to new organisms. Under the HSNO Act, which I'm now going to shorten my reference to, the Environmental Protection Authority, or what we know as the EPA, is the regulator responsible for making decisions on whether or not to approve new hazardous substances for use. The EPA sets the necessary controls to manage risk and to safeguard people and protect the environment. These controls set out conditions as to how a substance can be used. The EPA also reassesses hazardous substances already in use and makes decisions about whether the controls need to be updated and whether the substance should continue to be approved.
