Development And Cost-benefit Assessment Of Air Pollution Control Action Plan Of Shunde In 2015

Over the past twenty years, the Pearl River Delta(PRD) region achieved a substantial economic growth due to the rapid development of urbanization, industrialization and motorization. Shunde District, located in the hinterland of the PRD, are faced with multi-pollutant air pollution problems like other citys in PRD. To promote the air pollution control, the ministry of environmental protection and government of Guangdong province successively released the air pollution control action plan(2014-2017). Both action plans set stringent air quality targets for PRD region, requiring effective air pollution control strategies to be implemented in the near future. Due to the imbalance of control investment and air quality improvement in the past, our study performs integrated air quality attainment and cost-benefit assessment for the air pollution control strategy of Shunde while developing, guaranteeing the attainment for air quality targets and reasonable cost-benefit ratio of the control strategy.According to the air quality targets set by the government of Guangdong province, and the local air pollution characteristics in Shunde, our study developed the air pollution control action plan of Shunde in 2015. Based on the control plan, the correlated air pollution emission control strategy was developed, and simulated by the CMAQ model. The level of air quality attainment was predicted and the corresponding human health and economic benefits were evaluated through the mature software tools. The engineering cost was roughly assessed as the product of emission reduction and cost per unit reduction.Results show that the amount of attainable air quality monitoring sites of annual PM2.5 and PM10 concentration can reach up to 8 and 6 respectively. And the average annual PM2.5 and PM10 concentration of two national monitoring sites is 40.6μg/m3(target: 43μg/m3) and 60.3μg/m3(target: 66μg/m3), which indicates that the control plan can achieve the expected air quality improvement. For the engineering cost, the total estimates of end-of-pipe treatment is 34.956 million, 2.4%, 32.6% and 65% of which is contributed by the controlling cost from power plants, industrial boilers and industrial process sources; for the health and economic benefits, the total estimates is 35.56 million, 76.2%, 22% and 1.8% of which benefits from the reduction in the number of all-caused mortality, all-caused hospital admission and all- caused outpatient visit. In conclusion, the prepared air pollution control plan of Shunde in 2015 is a feasible, reasonable and cost-effective action plan.
