12. Industrial 1 and 2 Zones Volume Two 12.3.6.2. Any new seed cleaning operation commenced after 9 June 2016 must not be located within 100m of any sensitive receptor. 12.3.6.3. There must be no dispersal or deposition of contaminants beyond the boundary of the property where the discharge originates. 12.3.7. Discharge of contaminants to air from the spray application of paint or adhesive coating materials onto surfaces not within a spray booth, other than a road. 12.3.7.1. There must not be more than 5 litres of coating material applied per hour and not more than 20 litres of coating material applied per month. 12.3.7.2. Where there is a sensitive receptor on another property within 100m of where the spray coating is to occur, there must not be more than 0.5 litre of coating material applied per hour and not more than 5 litres of coating material applied per month. 12.3.7.3. Spray coating must not occur on surfaces of fixed structures that can be dismantled and transported to a spray booth. 12.3.7.4. The coating material must not contain di-isocyanates or organic plasticisers. 12.3.7.5. The discharge must occur at least 10m from a sensitive receptor beyond the boundary of the property where spray coating is undertaken. 12.3.7.6. There must be no dispersal or deposition of contaminants beyond the boundary of the property. 12.3.8. Discharge of contaminants to air from the application of coating materials (including paints and powders) through spray application undertaken within an enclosed booth located in the Industrial 2 Zone. 12.3.8.1. The coating material must not contain any di-isocyanates. 12.3.8.2. The total amount of coating material sprayed on the property must not exceed 10 litres per hour. 12.3.8.3. The spray booth must be fitted with an air extraction system which vertically discharges all contaminants and exhaust air through an emission stack. 12.3.8.4. The emission stack must be a height of at least 2m above the ridgeline of the roof of a building, land or other substantial structure within a radius, from the stack, of 35m. 12.3.8.5. The discharge must be directed vertically into the air and must not be impeded by an obstruction above the stack which decreases the vertical efflux velocity, below that which would occur in the absence of such obstruction. 12.3.8.6. The discharge must be through a filtration system that removes at least 95% of particulate matter from the discharge. 12.3.9. Discharge of contaminants to air from the combustion of fuel (i.e., external combustion). 12.3.9.1. The discharge must not contain more than the following maximum heat output limits: (a) 10MW for natural or liquefied petroleum gas; (b) 40kW for untreated wood; (c) 100kW for coal; (d) 40kW for light fuel oil; (e) 1.0MW for pellet fuel when burnt in a custom designed pellet boiler; 12 – 8
