10 Air Quality and Noise

Under the RMA, regional councils have responsibility for the management of air quality and noise within the CMA. However, for both issues an integrated management approach is critical.

Section 30(1)(d)(iv) of the RMA requires regional councils to control the discharge of contaminants into air. In addition, s15(2) of the RMA places restrictions on the discharge of contaminants into the air. Existing air quality in the CMA is perceived to be high. It has many characteristics that are valued by the regional community, including amenity values (i.e. good visibility, air free of offensive odours), low contaminant levels, intrinsic values and life supporting capacity. Land-based activities are the most likely source of air emissions to impact on the CMA, therefore, it is important that an integrated approach with regional and district plans is undertaken.

Section 30(1)(d) (vi) of the RMA requires regional councils to control the emission of noise in the CMA, while s16 places a duty on every occupier of land and every person carrying out an activity in, on or under the CMA to avoid unreasonable noise. Noise generated from within the coastal environment can affect amenity values of an area and impact on people above and below Mean High Water Springs. Control of noise in the CMA must therefore be managed in an integrated manner with territorial authorities.

As Mean High Water Springs is an arbitrary mark for the effects of noise and the discharge of contaminants into the air, it is important that an integrated approach consistent with landward activities is promoted.
