This project was empowered by a contract which issued by the Bureau of Environmental Protection, Tainan County. The project started on June 2007, and ended on June 2008. The percentage of the project is 100%.
For the work of emission inventory database update, the data of 706 stationary pollution sources has been checked and updated. The percentage of this work item is 101%.
In the management and issuance of permits,630 permits have been issued, including 61 installation permits, 51 modified permits, 144 operation permits,108 change permits, 182 renewed permits, 79 re-issued permits and 5 coal-fired permits. 61 cases of air pollution qualified persons replacement were proposed and approved. Periodic inspection for operation permits has been performed on 537 operation permits. Among them, 102 operation permits didn’t meet the contents of permits, and the discrepancy of inspection was 19%. Further, the plants have been asked to modify and improve the inconformity. 48 plants reported their modification or changes, and got new permits which fit their status quo. The percentage of improvement is 94.1%.
Under the air pollution control fee system, we enforce a revised system this year, including the fee rates revision of SOx and NOx and new VOC air pollution control fees collection. A total of678 stationary pollution sources are required to pay the air pollution control fees, and around 17 million dollars of air pollution control fee were collected on a seasonal base in Tainan County. Inspection for seasonal reports of air pollution control fees was performed on 320 plants during this stage. The plants which fail to make payments by the deadline were called by phone to track the payment. The percentage of seasonal application is 100% (from the beginning of 1st season to the end of 4rd season, 2007).
263 stationary pollution sources are required to report annual emissions by regulation in Tainan County(1st batch: 96 plants and 2nd batch: 167plants). The reporting rate of it has reached 100% (from the beginning of 1st season, 2007 to the end of 1rd season, 2008). Inspection for reporting annual emissions was conducted on 264 plants; 77.65% of it proved correct(205 plants), 21.21% of it showed discrepancy(56 plants).
Inspection by air pollutant testing was performed to fulfill the requirement, including 8 plumes for dioxin testing, 2 plume for Arsenic compound testing, 2 plume for heavy metals testing, and 12 plumes for SOx, NOx and/or Particle. All results show compliance with emission standards except 1 plumes for dioxin testing. We also took 20 fuel samples from different plants to check if the sulfur in the sample violets the standard (0.5%), and the result shows that 1 sample violets the standard.
A reference manual of Metallic processing industry for permit issuance is finished and approved by EPA. A map of stationary pollution sources in Tainan County is made. 10 project progress news were reported by newspaper for now.
Arsenic compound in semi-industrial plants of Tainan Science Park has been a hot issue since last year. So we investigate the possible sources of Arsenic compound emissions and perform Arsenic compound testing in both plumes and ambient environment around Tainan Science Park. We find that the ambient Arsenic compound concentrations range between 2.6 and 4.1 ng/m3 outside the Tainan Science Park, and between 2.0 and 5.5 ng/m3 in the Tainan Science Park.
For the next stage of the project, we will focus on the remains of work items, as well as keep the work performance and quality. The final goal is to make sure the compliance of regulation of every stationary source, keep the emission inventory updated and manage the collection of air pollution fee under system in Tainan County.
