5.3.1 PM2.5The predicted annual average PM2.5 concentrations are below the EPP(<strong>Air</strong>) guideline value of8 g/m 3 for all locations during all three modelled years (refer to Table 6.1, 6.2 <strong>and</strong> 6.3) .The predicted maximum annual average PM2.5 concentration is 4 g/m 3 , which occurs at Locations5, 7 <strong>and</strong> 8 during years 1 <strong>and</strong> 6.The predicted highest PM2.5 24-hour concentrations are below the EPP(<strong>Air</strong>) guideline value of 25g/m 3 for all locations during all three modelled years (refer to Table 6.1, 6.2 <strong>and</strong> 6.3)The highest predicted PM2.5 24-hour concentration is 21 g/m 3 , which occurs at Locations 7 <strong>and</strong> 8during year 11.5.3.2 PM10The predicted maximum 24hr average PM10 concentrations are below the EPP(<strong>Air</strong>) guideline valueof 50 g/m 3 for all locations during all three modelled years (refer to Table 6.1, 6.2 <strong>and</strong> 6.3) exceptat Locations 3, 4, 5, 7 <strong>and</strong> 8 during year 1, Locations 3, 5, 7 <strong>and</strong> 8 during year 6 <strong>and</strong> Locations 5, 7<strong>and</strong> 8 during year 11.The predicted maximum 24hr average PM10 concentration is 129 g/m 3 , which occurs at Locations7 during year 11 operations.The predicted 6 th highest 24hr average PM10 concentrations are below the EPP(<strong>Air</strong>) guideline valueof 50 g/m 3 for all locations during all three modelled years (refer to Table 6.1, 6.2 <strong>and</strong> 6.3) exceptat Locations 7 <strong>and</strong> 8 during years 1 <strong>and</strong> 6 <strong>and</strong> Locations 5, 7 <strong>and</strong> 8 during year 11.The predicted maximum 6 th highest 24hr average PM10 concentration is 79 g/m 3 , which occurs atLocations 7 during year 11 operations.5.3.3 TSPThe predicted annual average TSP concentrations are below the EPP(<strong>Air</strong>) guideline value of90 g/m 3 for all locations during all three modelled years (refer to Table 6.1, 6.2 <strong>and</strong> 6.3) .The predicted maximum annual average TSP concentration is 43 g/m 3 , which occurs at Locations7 <strong>and</strong> 8 during year 1.5.3.4 Dust DepositionThe predicted monthly dust deposition rates are below the EPP(<strong>Air</strong>) guideline value of4 g/m 2 /month for all locations during all three modelled years (refer to Table 6.1, 6.2 <strong>and</strong> 6.3) .The predicted maximum monthly dust deposition rate is 3 g/m 3 , which occurs at Locations 7 <strong>and</strong>8 during year 1.Codrilla Coal Mine Project - <strong>Air</strong> <strong>Quality</strong> & <strong>Greenhouse</strong> <strong>Gas</strong> Assessment - Addendum Report 5843R02V01_draft2Valkyrie Page 18 of 51
