Under its Inventory Multi-tiered Assessment and Prioritisation (IMAP) framework, initiated in July 2012, NICNAS has begun to evaluate about 3000 industrial chemicals listed in the Australian Inventory of Chemical Substances (AICS). Each of the three tiers of IMAP sees an increase in the assessment effort required, and the framework is being implemented in a staged manner. The first stage (which is expected to take 4 years to complete) involves examining chemicals through “at least Tiers I and/or II of the framework”. Tier I involves a ‘high-throughput’ assessment, at the end of which certain compounds will be considered not to pose an unreasonable risk to the environment or the health of workers or the general public. Any compounds identified as being of potential concern progress to Tier II (chemical-by-chemical evaluation), and the individual assessments for each chemical are made available for public comment. Almost 200 (mainly human health) Tier II assessments, covering the latest tranche of compounds, have recently been made available for comment (until 30 May 2014). Tier III, which has not yet begun, will involve an in-depth assessment of chemicals prioritised by Tier II.
