The "2024 Miaoli County Volatile Organic Compound Inspection and Odor Pollution Audit Control Project" was signed on March 1, 2024. The implementation of the project includes regulatory compliance check, sampling for VOCs vacuum stainless steel bottle analysis, functional odor testing, efficiency verification of prevention equipment, infrared leak scanning of equipment components, creation of fingerprint data, improving the factories that complaints by citizens, SOP submission, press releases, and automatic sampling equipment maintenance.
From the date of signing the project to November 20, 2024, detailed descriptions of the work are as follows: (1) The inspection standards in the regulations are based on the "Volatile Organic Compounds Air Pollution Control and Emission Standards". The inspection content mainly targets exhaust gas combustion towers, process facilities, loading operation facilities, storage tanks, equipment components, sewage treatment plants, and cooling towers. The audit has been completed for 30 process inspections. The main common deficiencies in the inspections are "The operating parameters of the control equipment are inconsistent with regulations" and "The difference between the declared quantity of equipment components and the permitted quantity is more than 10%";(2)VOCs vacuum stainless steel bottle sampling analysis, 10 sampling sites have been completed and some pollutants characteristic of public and private places have been found, such as vinyl chloride, 1,2,4-Trimethylbenzene, etc.;(3) Functional odor testing has been completed for 8 ducts and all match the standard. About 2 perimeter functional odor testing points, the Zhan Yun Xiang livestock farm detected an odor value of 45 over the area standard limit of 30;(4) The project has completed 1 validation for the activated carbon adsorption equipment. The efficiency test value of carbon adsorption equipment in The Treasure Lacquer Paint & Printing Ink CO., LTD was 56.8% which complies with licensing specifications and processing efficiency of over 20%; (5) The leakage scanning operation of the infrared line of equipment components has been completed for 6 processes. The 2 equipment of Tong Hsieh Chemical Industrial CO., LTD was inspected for leaks. The emissions reached standard after improvement;(6) Fingerprint data construction operation has been completed, and 8 ducts VOC species samples have been collected, all of which have been analyzed and documented. This project will continue to be implemented to complete the fingerprint database;(7) The project provided counseling to improve the factories that the public has submitted. This year, the project provided counseling to Lien Tai Paper CO., LTD. M04 and M06 which was some odor emission in the process area and Taiwan Shian Shing Technology CO., LTD. which the end of the process tube contained higher concentrations of ozone-generating potential species and there was specific emission in the process. Therefore, this project arranges for experts and scholars to enter the factory to perform coaching improvement and reduction operations;(8) VOCs automatic sampling and monitoring operations, 81 sets of monthly VOCs automatic sampling and monitoring operations have been completed, with a total of 11 locations and 9 pieces of equipment installed, the set up situation will adjust by seasonal wind direction or public complaints;(9) Press Release, 2 press releases have been written and published on the public platform;(10) The mobile air quality monitoring vehicle completed mobile monitoring at 3 locations, including the surrounding of Porite Taiwan Co., LTD, Zhunan Sports Park and Tianliau Village community center. Among them, monitoring around Zhunan Sports Park, after continuous search and research of relevant evidence, together with the Environmental Protection Bureau and the Fixed Licensing Plan, went into the factory to conduct inspections on the suspicious object - Huaxia Bay, and found many cases where the use of raw materials exceeded the maximum limit approved by the license. However, the usage amount was still within the 10% allowable error range. Therefore, the Environmental Protection Bureau ruled that no punishment would be imposed and the industry was required to improve the situation of large amounts of white smoke as soon as possible.
The team of this project will continue to carry out inspection operations and use equipment such as IoT sensors, automatic sampling equipment, and mobile air quality monitoring vehicles within the jurisdiction to analyze, compare, and manage the source of pollution, to effectively reduce the occurrence of petition cases. We will also conduct re-examinations for manufacturers that have deficiencies in regulatory compliance checks, and identify ways for manufacturers to improve. The manufacturers will make specific commitments to complete the improvement of the missing items to ensure the air quality of Miaoli County.
