13. Port Zone Volume Two 13.3.29. Discharge of contaminants to air from the burning of solid fuel in a small scale solid fuel burning appliance. 13.3.29.1. The appliance must comply with the emission, operational and other requirements of Appendix 8 – Schedule 1. 13.3.29.2. The appliance must comply with the stack requirements of Appendix 8 – Schedule 2. 13.3.29.3. The appliance must only burn fuels approved for use in the appliance. 13.3.29.4. The appliance must be operated so that all reasonable steps are taken to minimise the amount of smoke discharged. 13.3.30. Discharge of contaminants to air from the production of fibreglass and other composite materials or from the production of plastic products and plastic moulding operations. 13.3.30.1. The fibre glassing must be undertaken inside a booth equipped with filtration, extraction and dispersion mechanisms to ensure 95% particulate removal. 13.3.30.2. The total amount of plastics moulded on the site must be less than 500kg per hour. 13.3.30.3. The total amount of fibreglass and resin used on the site must not exceed 50kg per hour. 13.3.30.4. The total mass of organic material discharges from the site must be less than 5kg per day. 13.3.30.5. Any point of discharge to air must be 2m above the highest point of the building containing the operation or any building located within a radius of 2.5 times the height of the discharge. 13.3.30.6. The air discharge must be vertical. 13.3.31. Discharge of contaminants to air from water blasting or from dry abrasive blasting, other than from the use of a moveable source. 13.3.31.1. There must be no discharge of water spray, dust or other contaminant beyond the boundary of the property. 13.3.31.2. Where the discharge occurs from public land there must be no discharge of water spray, dust or other contaminant beyond 50m from the discharge point or beyond the boundary of the public land, whichever is the lesser. 13.3.31.3. There must be no discharge of water spray, dust or other contaminant into the coastal marine area. 13.3.31.4. The surface to be blasted must not contain any hazardous substances, including lead, zinc, arsenic, chromium, copper, mercury, asbestos, tributyl tin, thorium-based compounds, and other heavy metals including anti foul paint containing these substances. 13.3.31.5. For dry abrasive blasting all items must be blasted within an abrasive blasting enclosure and the discharge must be via a filtered extraction system that removes at least 95% of particulate matter from the discharge. 13.3.31.6. For dry abrasive blasting the free silica content of a representative sample of the blast material must be less than 5% by weight. 13 – 16
