This paper presents the benefits in terms of air quality from the decommissioning of the coal-fired Liddell Power Station (LPS) in the Greater Metropolitan Region of Sydney (GMR). The impact on air quality (NO, NO2, O3 and PM2.5) are modelled using CCAM-CTM air quality model and the results show that the difference in annual average concentration is small. For NO, the maximum difference is 1 ppb, while for NO2 the value is 0.75 ppb. These are annual average decrease of NO, NO2 concentration over the GMR. The most significant decrease of NO and NO2 occurs in the Upper Hunter near the LPS. For ozone (O3), the reduction of NOx emissions from LPS decommission resulted in a slight increase of O3 over a narrow area near the facility but this increase is gradually decreasing further away from the facility. The increase in O3 is about 0.65 ppb max around LPS. For PM2.5, the annual average decreases in most of the domain. The maximum change is at LPS (about 0.19 µg/m³). [ABSTRACT FROM AUTHOR] |
