(Ⅰ) Implementation of Pollution Source Control and Reduction during Poor Air Quality
1.Enhanced Response Effectiveness:
At the start of the project, a list of response audit targets was established, including 60 public and private places with approved "Air Quality Deterioration Prevention Plans", potential hot spots from micro-sensor data, and controlled targets for "Air Pollution Prevention Actions" in Tainan City (including 13 asphalt concrete plants, one port area cement handling site, 28 boiler industries, and 13 volatile organic liquid storage tanks).
A complete reporting mechanism for pollution sources was established, with reporting operations executed during periods of poor air quality.
2.Response Inspection Mechanism:
A response inspection mechanism was planned based on the frequency of IoT system alerts in industrial areas and current weather conditions (wind speed, direction), selecting inspection areas and response inspection lists according to the day's indicator pollutants (suspended particles, volatile organic gases).
3.Response Actions:
During the project period, there were 83 days with air quality warnings at or above the preliminary alert level. Inspections were carried out at 264 public and private locations, including 237 factories and 27 construction sites. Of these, 34 factories were found to have deficiencies, mainly due to incomplete records (51.16%), damaged or malfunctioning control equipment (18.60%), and control equipment exceeding permit values (23.26%). Four construction sites had deficiencies, mainly due to unclean or insufficiently thick travel paths.
Significant reductions were achieved: TSP (Total Suspended Particulates) reduced by 686.99 tons, PM10 reduced by 134.05 tons, PM2.5 reduced by 30.74 tons, and NOx reduced by 400.34 kg.
4.On-Site Inspections:
During air quality preliminary warnings, on-site inspections of 20 public and private places' regional air quality deterioration prevention plans were conducted. Many factories had not practiced related response drills, and some factories' process flow charts or permits had not been updated.
5.Participation in Related Meetings:
Participated in 9 response team meetings and 6 joint inspections with Yunlin-Chiayi-Tainan and the Environmental Protection Administration's cross-regional cooperation response team during the poor air quality season.
(Ⅲ)Major Pollution Source Detection and Tracking During Poor Air Quality
1.Infrared Gas Imaging Camera Inspections:
Inspected 13 high-pollution potential factories for leaks, with improvements completed and no leaks found upon re-inspection at two locations.
2.VOC Inspections:
Conducted VOC inspections at 11 locations, testing 8,000 equipment components, including 945 difficult-to-inspect components (12.5%). Detected leaks at 10 points, with one point meeting regulatory leak definitions, resulting in legal action.
3.Odor Pollution Source Sampling:
Conducted three odor pollution source sampling operations, with all detection values meeting standard levels.
4.UAV Aerial Inspections:
Conducted 10 UAV aerial inspections, including joint inspections with the southern six counties and targeted open burning inspections, detecting 8 open burning incidents with no perpetrators found on site. Additionally, inspected industrial areas, detecting 7 abnormal pollution sources.
(Ⅳ) Environmental Protection Administration Performance Tracking in 2023
1.Assistance in Performance Assessment:
Assisted the Environmental Protection Bureau in securing a full score for the performance assessment item "Cross-Regional Cooperative Response during Poor Air Quality Season (January-March and October-December)".
2.Cross-Regional Cooperative Response:
Participated in 20 joint inspections with Yunlin-Chiayi-Tainan and Kaohsiung-Pingtung air quality areas during the poor air quality season.
