3 What are the new NRSIEE emission standards? Australian emission standards for NRSIEE will be based on those applied in the US and administered by the US EPA. The US EPA has both exhaust and evaporative emission standards. However, evaporative emission standards will not be adopted in Australia at this stage (see Section 3.2). Table 1 gives an outline of the exhaust emission standards applied by the US EPA. The detailed Australian emission standards (emission limits) for NRSIEE and their requirements will be set out in a Rule., Information on the commencement dates for the exhaust emission standards for NRSIEE is provided in Section 6 of this paper.
