This scheme was carried out from July 2, 2016 to July 1, 2017, with the main tasks of monitoring, oversight, and evaluation of the execution quality of the air pollution control fund plans. The objectives are to ensure that the expected goals can be met, and the concrete achievements and special outcomes can be integrated to meet the evaluation of the Environmental Protection Administration (EPA). Other tasks include updating the environmental loading and pollutant discharge data of this county, analyzing the air quality monitoring results, and discussing the causes of the poor air quality incidents. The results are provided to the Bureau of Environmental Protection as a reference for modifying the short-term air pollution control strategies.
It is analyzed in the monitoring station of Environmental Protection Administration in Taoyuan City from 2008 to 2016 (excluding the effect of dust storm) that the air quality is poor (AQI>100). The station days in various stations show that the condition is improving year by year; in the aggravating station days of poor air quality (AQI>100), PM2.5 accounts the largest proportion, indicating that PM2.5 remains to be the major cause of poor air quality. The air pollutant concentration in Taoyuan City in 2016 has been improved. In addition to PM2.5 manual and automatic annual mean value and O3 8-hour 8 values, the rest pollutant concentrations meet the air quality standard.
Concerning the supervision and management of plans of air pollution control strategies, this scheme checked the execution progress and quality of the plans on a monthly basis, compiled the results for the Bureau of Environmental Protection as a reference to propose improvement plans. In order to establish the overall direction of this scheme, three session of training seminar on air pollution control and management, one session of air quality control of domestic and foreign exchanges, one session of air pollution prevention and control related conferences, six sessions on field supervision, two sessions on work review and expert consultation, one sessions on internal work coordination, one session communicate with North Air Quality Area, and three session assist transact air-pollute fund committee permit conferences, one air pollution improvement efficiency forum seminar and air quality flag explanation meeting thus improving the work performances and execution quality.
According to the emergency measures for poor air quality, it is counted that there are respectively 76 and 62 days for poor air quality (AQI>100) in Taoyuan City in 2015 and 2016. The main indicator pollutants of poor air quality are PM2.5 and O3. The poor air quality reporting and response measures have been implemented for 51 times in Taoyuan City; when AQI>100 and AQI>150, environmental protection bureau should inform the manufacturers to carry out independent emission reduction and inspection work.
In terms of implementation efficiency of air quality improvement and strategy discussion and formulation, the data are collected and analyzed every month from automatic monitoring station of Environmental Protection Administration, air quality monitoring station established by this city on its own, and special report on air quality analysis is made quarterly. According to “Plan for the Prevention and Control of Air Pollution in Taoyuan City” and special analysis on air quality, the in-depth research is conducted against SO2 pollution faced by this city and air quality pollution contribution is used to make a simulated analysis of pollution condition of Guishan Industrial Area, so as to provide the reference for the follow-up control strategies. Besides, the corresponding control strategies should be formulated for air quality problem, including review and modifying various objectives in the air pollution prevention plan as well as putting forward emission pattern analysis of effusion source and aerosol, so as to master the emission characteristics of effusion source PM in this city. According to the research results, it is suggested that emission coefficient of PM2.5 of material pile in this city should be indicated as: EF (g/ton.day) =7.87(s/1.2) 0.57 (U/2.5) 1.05(m/10) -0.46.
In order to understand people’s satisfaction degree for the control and administration work, the questionnaire on the public opinion of air pollution prevention and control achievement is made. The questionnaire survey on the public’s air quality satisfaction is conducted and the results show that the public show the maximum satisfaction for the subsidy of old vehicle liquidation in 2016. The pollution source which the public want to preferentially manage most is that the road cumulated dust in 2013 is changed to factory waste gas in 2016. Therefore, it is suggested that the inspection for the emission of factory waste gas should be placed as the important work items.
In other cooperating projects, this plan has completed the formal migration assessment operation and migration operation of default monitoring station this year. Moreover, the micro monitoring technology has become mature in recent years. In order to have a better understanding of pollutant emission source in various regions, this city applied new micro monitoring technology to conduct regional analysis in detail. At the end of April 2017, 20-point installation and test operation have been completed to preliminarily analyze the monitoring results of micro monitor in May. The abnormal high value easily appears around Hsiang An Elementary School and De Long Elementary School. It is suggested that the continuous observation should be conducted in this region in the follow-up research and the surrounding manufacturers should also be inspected to see whether there is suspicious pollution source.
