16.1004.FR1A.V1 PART A COMMON STUDY COMPONENTS Part A | Page 79 CHAPTER 5: METHODOLOGY Impact Magnitude Magnitude is a descriptor for the predicted scale of change to air quality conditions that may be attributed to the Proposal. In this report, the magnitude of air quality impacts is determined through a predictive dispersion modelling assessment. The impact predictions are compared against the relevant compound-specific toxicity criterion and odour criterion (see Part A, Section 3) to derive the corresponding magnitude of impacts for that contaminant using the methodology presented in Part A, Table 20. Table 20 Operational Phase Magnitude of Impacts Magnitude Description Examples Substantial Impact is predicted to cause significant consequences on the receiving environment A significant change which involves a variation in predicted concentration by > 10% of a long-term criterion or 50% of short-term criterion, or lead to an exceedance of the relevant criterion. Substantial risk that the impacts would generate nuisance complaints, resulting in regulatory action. Moderate Impact is predicted to possibly cause statutory objectives / standards to be exceeded A noticeable change which involves a variation in predicted concentration of 5% to 10% of long-term criterion or 25% to 50% of short-term criterion. Moderate risk that the impacts would generate nuisance complaints, resulting in regulatory action. Slight Predicted impact may be tolerated. A barely measurable change which involves a variation in predicted concentration of 2.5%-5% of long-term criterion or 10% to 25% of short-term criterion. Slight risk that the impacts would generate nuisance complaints, resulting in regulatory action. Negligible Impact is predicted to cause no significant consequences. A negligible change which involves a variation in predicted concentration of < 2.5% of the long-term criterion or < 10% of the short-term criterion. Negligible risk that the impacts would generate nuisance complaints, resulting in regulatory action. To provide quantitative assessment of impact magnitude, the AQRA is underpinned by a dispersion modelling study. The impacts associated with the operation of the Proposal at Chandler and the potential impacts from the loss of containment of containerised product salt, solid waste and sludge / liquid wastes at the Apirnta Facility, Chandler Facility and on the interconnecting transportation routes has been assessed through the use of dispersion modelling studies.
