The main work items of Stationary air pollution source control project are:(1)Database establishment, system function upgrade and data QA/QC. (2)Stationary Sources Permit application documents exam and issue, including permit inquisition. (3) Report and check of air pollutant emissions quantities. (4)Inspection by air pollutant testing. (5)Training for dedicated air pollution control personnel.(6) Check of cems.
This project was empowered by a contract which issued by the Bureau of Environmental Protection, Tainan County. The project started on July 2011, and will be ended on December 2011. The percentage of the project is 100%. The progress for each work task is outlined in detail as below.
1.Database establishment, system function upgrade
For the work of emission inventory database update, the data of 414 stationary pollution sources has been checked and updated. The percentage of this work item is 103.5%.
In the management and issuance of permits, 207 permits have been issued, including 14 installation permits, 5 modified permits, 33 operation permits, 58 change permits, 47 renewed permits, 46 re-issued permits and 4 coal-fired permits.
Periodic inspection for operation permits has been performed on 322 operation permits. Among them, 26 operation permits didn’t meet the contents of permits, and the discrepancy of inspection was 8.1%. Further, the plants have been asked to modify and improve the inconformity. 21 plants reported their modification or changes, and got new permits which fit their status quo.
3. Report and check of air pollutant emissions quantities
317 stationary pollution sources are required to report annual emissions by regulation in Tainan City. The reporting rate of it has reached 100% (from the beginning of 2nd season to the end of 3rd season, 2011). Inspection for reporting annual emissions was conducted on 162 plants;93.8% of it proved correct(152 plants),6.2% of it showed discrepancy(10 plants).
4. Inspection by air pollutant testing
Inspection by air pollutant testing was performed to fulfill the midterm requirement, 2 plume for heavy metals testing, and 15 plumes for SOx, NOx and particulate. We also took 38 fuel samples from different plants to check if the sulfur in the sample violets the standard (0.5%).
5. CEMS check results
During the implementation of the project, there were a total of 6 times of the flue relative accuracy test audit (RATA)operations,8 times of opacity(OP)calibration error check, 8 times of Cylinder Gas Audit(CGA)check, the results of the audit were all qualified; the other 3 times of the nitrogen dioxide test were also conducted. The results of one relative accuracy test audit (RATA) on Flue of CEMS implementation and the opacity (OP) calibration error all in compliance with the standards.
Monthly report of CEMS reviews ,and monthly comment reviews for the revised situstion were conducted. And defects occurring in the monthly report during the year have been gradually improved. In addition, transmission of the daily and monthly data and percentage statistics of the effective monitoring also completed. This year the factory of CEMS can transmit data on time and percentage of the effective monitoring hours can reach over 85%.
As for the on-site evaluation, in this year we have done 2 on-site evaluations and found the main defect lies in the test results with the system error, report mistakes and poor equipment efficacy,which were followed by our working group.And we also provide relevant information for the counseling facility to further improve things.
6.General patrol ：Total of 592 times of patrol assignment were conducted.
7. Other work items
(1) 4 articles of environmental protection news were posted.
(2) 45 cases of air pollution qualified persons replacement were proposed and approved.
(3) Case Handling for the Notification of the Air Quality Deterioration Total of 9 cases were notified during the project period and patrol staffs were then sent out to check on 9 public or private premises.
