Volume Two 3. Rural Environment Zone 3.4.1.3. Noise from a frost fan which has special audible characteristics such as tonality or impulsiveness, must have a 5 dB penalty added to the measured level before compliance with Standard 3.4.1.1 is assessed except that where the Reference Method in the Standard is used to determine the penalty, the value of the penalty shall be a value in the range 0.1 dB to 6.0 dB as determined by that method. 3.4.1.4. The frost fan must only be operated for protection of crops from frost from bud burst to harvest, with the exception that frost fans may also be operated in the following circumstances: (a) for the purposes of maintenance and testing, limited to operation between 8.00 am to 5.00 pm on any day; (b) for compliance monitoring at any time when the monitoring is undertaken by the Council or, where the monitoring is undertaken by a third party, when the Council has been notified. 3.4.1.5. When protecting crops from potential frost damage, a frost fan must only be operated in wind speeds not greater than 8km/hr (averaged over periods not greater than 5 minutes) and when the local air temperature is less than 1C. o For the purposes of this Standard, temperature must be measured within the property to be protected, for vineyards at the lowest fruiting wire and for other crops at the lowest point of the bud height (above ground level) of the plants being protected. 3.4.1.6. The frost fan must not be located within 500m of any land zoned Urban Residential 1, Urban Residential 2 (including Greenfields), Urban Residential 3, Business 2 or within 300m of a Rural Living or Coastal Living Zone. 3.4.1.7. An application to erect a frost fan must include the following information: (a) details of the proposed frost fan(s), including make and model, manufacturers’ specifications, blade type and configuration, drive motor details, and design speed of the tips of the blades; (b) a plan showing the location of the proposed frost fan(s) (with accurate NZTM coordinates) and area it is designed to cover; (c) a plan showing the location of the nearest dwelling, visitor accommodation or habitable building, or the nearest land zoned Urban Residential 1, Urban Residential 2 (including Greenfields), Urban Residential 3, Business 2, Rural Living or Coastal Living, and the distance to it; (d) detail of all means to ensure the performance of the frost fan and noise levels remain as predicted, including measures to govern the blade tip speed and the cut-off mechanism for winds exceeding 8km per hour; (e) a report prepared by an appropriately qualified and experienced acoustic consultant addressing the following: (i) a full and detailed description of the proposed frost fan; (ii) prediction of the noise contours of the proposed frost fan based on operational parameters specifically identified in the report for the particular location where the frost fan is proposed to operate, except where that frost fan has been certified by a body approved by the Council and the proposed fan is to be located and operated in accordance with that certification. 3 – 30
