The notified polymer will not be manufactured or reformulated in Australia. Therefore, release of the notified polymer from these activities is not expected. The notified polymer will be imported as an additive in diesel fuel. Environmental release of diesel fuel containing the notified polymer from spills is expected during refilling of the diesel fuel. Spills during refilling of the diesel fuel to underground storage tanks from isotainers and to car fuel tanks at fuel bowsers are expected to be insignificant (< 1% of the total import volume). These spills are expected to be contained in on-site interceptor drains at service stations to trap and filter the diesel fuel containing the notified polymer. Hence, the notified polymer will be prevented from entering the sewer via rainwater runoff. Empty import containers containing residues of the notified polymer are expected to be recycled by accredited waste management companies or disposed of according to local regulations. Residues of diesel fuel containing the notified polymer in isotainers are expected to be reused during transporting the diesel fuel. Most of the notified polymer will be consumed during engine operation to form water and oxides of carbon and nitrogen. No significant release of the notified polymer to aquatic systems is expected when it is used as diesel fuel additive. The notified polymer contains side-chains that may hydrolyse under severe conditions but due to its limited water solubility, the notified polymer is expected to be stable under normal environmental conditions. Based on its high molecular weight and limited water solubility, the notified polymer is not expected to be bioavailable nor bioaccumulative. Therefore, based on its assumed low hazard and assessed use pattern, the notified polymer is not considered to pose an unreasonable risk to the environment.
