Particulate pollutants found in atmosphere, depending on their sources, are recognized as primary pollutants and secondary pollutants. Primary particulate pollutants, depending on their sources, fall into two categories – exhaust emissions and fugitive. According to the Taiwan Emission Data System (TEDS 9.0 with 2013 as the benchmark year), the top 5 readings of PM10 and PM2.5 emissions by county/city are Kaohsiung City, Taichung City, Taoyuan City, Tainan City, and New Taipei City, where Kaohsiung City ranks first and Taichung City the second. Nationwide primary pollutant emission (PM10) by volume is 167,000 tons per year, 53.6% of which is fugitive pollutants comprising from vehicle-based road dust (20.1%), construction projects (16.2%), industrial production (17.3). Fugitive particulate pollutants are the primary concern for our country’s particulate pollutant control effort.
This Project aims to assist the Environment Protection Administration with its initiatives of fugitive particulate pollutant control, policy formulation, and supervisions on local-level environment protection agencies’ performance and regulatory efficacy. The implementation objectives of this Project are described in below:
1. Review and amend the laws governing fugitive particulate pollutant control and introduce pollutant source control;
2. Fully utilize information of pollutant sources and their respective prevention and regulation and materialize all pollution control tasks; and
3. Help to enhance performance of fugitive particulate pollutant control tasks at local-level and provide necessary assistance.
This Project has contributed in this fiscal year to the amendment of the Management Regulations for Construction Project Air Pollution Control Facilities by revising the considerations of the status quo at pollution control areas, adopting prioritized particulate matter reduction rules in 3-tier control areas and raising standards for obligatory assistance and burden of proof pertaining to pollutant source control. In addition, this Project has partially revised rules for pollution prevention and control facilities according to county- and city-level environment protection authorities’ regulatory and enforcement needs.
In terms of pollution source inspection, this Project has completed compliance inspections at 104 construction sites, of which 64 are determined as compliant, with a total compliance rate of 61.54%. Among the sources of fugitive particulate matters other than construction sites, 104 sites have been inspected, of which 51 are determined as compliant, with a total compliance rate of 49.04%. Follow-up requests of satisfactory improvement have been made to local environment protection authorities. 59 missions of aerial photography on bare land have been made, and the results have been relayed to the respective county- and city-level environment protection authorities for follow-up improvement reports, effectively keeping pollutions at bare land under watch. In terms of dirty and dusty road inspections, total 175 road pollution cases have been reported in this fiscal year; all of which have been rectified by the respective counties and cities. In addition, total 1,220 inspections on loading compartment covering of vehicles in operation have been made; of which 777 are determined satisfactory with a total compliance rate of 63.7%.
Public construction air pollution prevention and control facilities evaluation conducted in this fiscal year has produced suggestions and comments of improvements for the public project owners, and public construction quality is increased, air quality improved. In addition, pollution control is materialized through pollution source inspection, aerial photography on bare land, road inspection, operating vehicle cargo compartment covering inspections and pollution source prevention and control information collection.
