Marlborough Sounds Resource Management Plan 7.3 Issue Enabling the community to provide for its health and wellbeing. Rules within the Plan manage air quality by allowing discharges from industrial or trade premises (subject to various conditions) and regulating all other discharges from premises. Many of the rules in the Plan are therefore directed at allowing a range of activities to continue, while ensuring that any adverse effects on air quality are avoided, remedied or mitigated. 7.3.1 Objectives and Policies Objective 1 The adverse effects of discharging contaminants into air be avoided, remedied or mitigated, including adverse effects on local ambient air quality, community wellbeing, amenity values, resources or values of significance to tangata whenua, ecosystems, and water and soil. Policy 1.1 Ensure that all persons discharging contaminants into air, avoid, remedy or mitigate any adverse effect arising from that discharge. This includes all effects likely to be noxious, dangerous, offensive, or objectionable to such an extent that there is an adverse effect on the environment. Policy 1.2 Promote measures which avoid or reduce the discharge of contaminants to air at their source. Policy 1.3 Ensure that any measures adopted to avoid, remedy or mitigate the effects of discharge of contaminants to air, take account of the alternative receiving environments. Policy 1.4 Promote the use of industry guidelines as a means of reducing the effects of discharges from industrial premises. Policy 1.5 Promote an appropriate roading hierarchy as a practical means to reduce the adverse effects of vehicle emissions. Most discharges to air are waste disposal in that they contain unwanted by- products of processing. It is now standard practice to minimise waste at source. These policies apply this principle to the discharge of contaminants to air. Measures to control discharges can themselves have an impact on the environment. For example, scrubbers using water can contaminate water with heavy metals, and hence the need to mitigate the effects of mitigation measures. 7.3.2 Methods of Implementation Rules Rules enable the discharge of contaminants to air from industrial trade premises and other potentially significant point sources by: • Permitting with conditions, discharges which have no, or only minor, adverse effects on human health, amenity values, or natural and physical resources. 7 4
