The main work items of Stationary air pollution source control project are as follows: (1) Database establishment, maintenance and updates. (2) Stationary Sources Permits application documents examining and issuing, including permit inspection. (3) Annual emissions quantities checkfor the premises which have been announced in 2 batches. (4) Using standard air pollutant testing methodto inspect plumes of stationary sources. (5)Reinforcing control of fugitive particulate emissions. (6)Holding meetings for related policies or law announcement. (7) Reinforcing control of dioxin. (8) Reinforcing control of the premises odor complaintsregarding stationary sources from citizens. (9) Inspection of factories when air quality deterioration. (10)Other workitems.
This project, started from 10th April 2018 till 9th April 2019, was empowered by a contract which issued by the Bureau of Environmental Protection, Tainan City. We completed all work items before deadline. In order to make sure that the quality and quantity both met the requirements of the contract, we attended the monthly meeting of the Bureau, and followed internal QAQC plan. Schedule and quality of every work items also had been reviewed by the State Implement Plan, in order to ensure all requirements were met. Summaries of work items are as follows:
1. Database establishment, maintenance and updates
The goal of this work item is to maintain and update the emission inventory of 725 plantsand to add new emission inventory of 30 plants in database. We maintained and updated the emission inventory of 727 plants and added new emission inventory of 34 plants in database.
By the end of the project, annual emission quantities of different pollutants from stationary sources in Tainan City are as follows: 2,429.5tons of particles, 2,046.6tons of SOx, 3,545.2tons of NOx and 4,131.9tons of VOCs.
2. Stationary Sources Permits application documents examining and issuing, including permit inspection.
482 permits were issued, including 53 installation permits, 12 modified permits, 69 operation permits, 150 change permits, 128 renewed permits, 62 re-issued permits and 8 coal-fired permits. The average review duration of the application documents was 17 days. 145 cases of air pollution qualified persons replacement were proposed and approved. For 10 significant cases of permit application, experts review was introduced to validate the content of the documents.
Periodic inspection for operation permits has been performed for 741 operation permits. Among them, 111 operation permits didn’t meet the contents of permits, and the discrepancy of inspection was 15%. Furthermore, the plants were asked to modify and improve the inconformity.
3. Annual emissions quantities check for the premises which have been announced in 2 batches.
354 premises are required to report emission inventory seasonally by regulation in Tainan City. (108 of them are announced in first batch, and 246 of them are 2nd batch.) The reporting rate, for a total of 1455 reports, is 100% from 1th quarter, 2018 till 4th quarter, 2018 We also checked all reports and found that 1361 of them (94%) were correct, 93 of them (6%) were asked to improve within a limited time. On-site inspection for the reports was conducted on 261 premises; 95.8% of them proved correct (250 premises), 4.2% of premises, which was asked to improve within a limited time, showed discrepancy.
4. Using standard air pollutant testing method to inspect plumes of stationary sources.
We performed 6 plumes for dioxin testing. We also took 20 fuel samples from different plants to check if the sulfur content in the sample met the standard.
5. Control of Fugitive Dust Air Pollution from Stationary Pollution Sources.
This work item is to inspect the premises which have been specified by Management Regulations of Air Pollution Control Facilities for Fugitive Particulate Emissions of Stationary Source and to help them improving the discrepancy. 192 patrols were paid and 177 of them met the regulation, the compliance rate of the regulation was 98.51%.
6. Reinforcing control of dioxin.
There are 52 plants (71 plumes) in the dioxin control list. On-site regulation inspection was performed on 32plants (40 plumes). 41 plumes were completed the testing.
7. Reinforcing control of the premises odor complaints regarding stationary sources from citizens
Periodical check for the frequent odor complains factories list of stationary sources. 363 patrols were performed, including 4 industrial parks in Tainan City.
10 stack odor inspections were performed, 3 of them was not compliance with the standard.
8. Other work items
(1)5 articles regarding environmental protection were posted in newspapers.
(2)To cooperate with polices and attorneys for comprehensive inspection for 6 times and checking the gravel trucks for cover net pulling compliance policy for 8 times.
(3)To help determining if plumes meet the 8D/2D requirements when applying permits as well as if they should apply for permits.
(4)To submit and summarize the work results as the Environmental Protection Administration (Taiwan) and the State Implement Plan required.
