The source of particulate matter in the atmosphere are classified as primary and secondary pollutants; granular primary pollutant sources include pipeline emissions and fugitive emissions. Based on data from the Taiwan Emission Data System (TEDS 10.0, base year 2016), the distribution of emissions across all cities and counties show that PM10 and PM2.5 are primarily distributed in the five cities of Kaohsiung, Taichung, Taoyuan, Tainan, and New Taipei, with Kaohsiung accounting for the most followed by Taichung. Emissions of primary pollutants (PM10) across the nation is 14.8K tons/year and in terms of fugitive emissions, vehicle dust accounts for 22.3%, construction projects account for 14.8%, industrial manufacturing accounts for 10.5% for a total of approximately 47.6%. Particulate matter of fugitive emissions is the control focus of Taiwan’s particulate matter regulation.
This project primarily assists the Environmental Protection Administration in the investigation of current air pollution prevention mechanisms in cities and counties as well as providing suggestions in emergency responses for air quality. Additionally, the project supervises local environmental protection authorities in executing pollution control and implementing effective policies to control particulate matter for the purpose of improving air quality. The targets of this project include:
1.Promote management standards for pollution sources, review the relevant laws and standards for control of effusion sources of particulate matter based air pollution.
2.Investigate the conditions of fugitive emissions of particulate matter from roads and port regions as well as plan and promote measures to control pollution.
3.Provide local support for the effective control of fugitive emissions, such as information, administrative, and technical support.
In terms of investigating pollution sources, 43 out of 110 construction sites investigated were found to be compliant with legal regulations, meaning 39% of companies were found to be free of violations. In terms of stationary emission pollution sources, 52 of the 110 sites investigated were found to be compliant with laws governing fugitive emission sources of pollution, meaning 47% of companies were found to be free of violations. We have already requested local environmental protection authorities to supervise these businesses in the installation of improvements; 10 advisory seminars for pollution prevention in public construction were conducted in addition to issuing notices with suggestions for improvement to monitored departments. A total of 1,123 km of road have been patrolled and inspected for pollution with a total of 276 cases of pollution reported; all cities and counties were notified to complete improvements and report all results in due course. Investigations of cargo hold covers was performed on 887 trucks currently in service; 722 vehicles were found to be compliant to regulations for a compliance rate of 81%. Commercial ports must improve air pollution prevention controls for barren and exposed land, cargo handling, and driving routes to comprehensively achieve the prevention of particulate matter from fugitive emissions.
During fall and winter, which are often seasons with poor air quality, monitoring of the cargo handling of cement clinker ships will be increased in coordination with relevant departments to supervise operators and ensure they comply with pollution prevention; investigation and analysis of street pollution will be conducted to identify the sources of road dust and develop countermeasures. By investigating pollution sources through roadway patrol and identifying street pollution, we can better control and prevent pollution sources to achieve various pollution controls.
