1. Reason for revision
As Article 36.1-3.2 Article 38-2.9, and Article 44.x of Clean Air Conservation Act are established (Promulgation on April 14, 2021 and enforcement on October 14, 2021) for possible withdrawal of permission and business closing in case of violation of the condition for permission of air pollutant emission facilities or no execution of correction order of VOC emission facilities, it is intended to specify the standard on administrative measures delegated by acts and to improve and supplement some insufficient points found in operation of current system by such method as preparation of the basis for common use of administrative information when reporting fugitive emission facilities.
Also, it is intended to apply emission allowance standard of fixed-roof storage facilities flexibly with cost-effective link to control hydrocarbon (THC) of storage facilities and to add facility supplementation methods such as prevention of leakage from the gap between rising roof and storage facility inner walls for application of air pollutant emission reduction method of inside-rising roof storage facilities and closing of openings, etc.
2. Main content
A. The standard on detailed administrative measures is established against violation of permission condition of air pollutant emission facilities (Appendix Table 36 ii A 3 of draft).
B. Detailed standard on administrative measures by times is established against business closing or violation due to no execution of correction order to fugitive emission facilities or VOC emission facilities (Appendix Table 36 ii C 1) d), ii C 5) a), and ii C 5) d) of draft)
C. Citizens’ convenience is sought for by conforming factory registration certificate through common use of administrative information in administrative offices when reporting fugitive emission facilities.
D. Improvement of applicable standard on allowance of emission of storage facilities (Appendix Table 8 ii A Remark 11 of draft)
- When inside-rising roof storage facilities and preventive facilities are connected in fixed-roof storage facilities, if THC concentration is reduced by 95% or more, emission allowance standard is not applied.
E. Improvement of facility management standard to reduce fugitive emission from inside-rising roof storage facilities (Appendix Table 10-2 iii A 3) b) (6), (7), and (8) and C 2) b) (6), (7), and (8) and Remark 6) of draft)
1) As installation of gas processing facilities is only prescribed as pollutant emission reduction method from inside-rising roof storage facilities being operated without consideration of the properties of individual storage facility being operated, it is made possible to select and apply pollutant reduction measures depending on the kind of storage facilities and stored materials.
2) The measure to supplement facilities is added to reduce leakage in addition to install processing facilities to reduce emission of gas from inside-rising roof storage facilities.
- In case of inside-rising roof storage facilities to store fluid containing benzene or toluene, etc. at certain or higher level, the gas is processed with installation of the processing facilities and, in case of other facilities, the gas is processed with installation of the processing facilities or facility supplementation measures such as prevention of leakage from the gap between inner wall and rising roof of storage facilities and strengthened closing of openings of rising roof are taken.
