Therefore, pollution control of this kind pollution sources is effective management for the air pollution. Since 1993, Environmental Protection Administration (EPA), R.O.C (Taiwan), has batchly announced about establish of Continuous Emission Monitoring Systems (CEMS) for large stationary pollution sources, and before 2002, the CEMS signal must continue to transmit to EPA. Meanwhile, on Dec 3rd, 2003, government revised the articles in "Continuous Automatic Monitoring Facility Management Regulations for Stationary Air Pollution Source." to standardize the continuous automatic monitoring facilities, software and quality assurance operation to implement flue monitor operation in the factory. In this study, analyses have been carried on the checking results done by former Environmental Protection Bureau Kaohsiung City Government (EPB). (from Jan 1st, 2006 until Dec 31st, 2010) on 40 flues in 16 factories. The checking items include Opacity Audit (OPA), Cylindrical Gas Audit, (CGA) and Relative Accuracy Test Audit (RATA). The standard deviation of OPA and CGA are 3% and 15% respectively. The distributions of the standard deviation in OPA, CGA and RATA are 0.00%-2.10%, -40.91%-26.29% and 0.23%-19.5% respectively. OPA results show the longer the instrument operates the worse the instrument performs. Otherwise, CGA results demonstrate the instrument performance has no relationship with instrument type and lifespans. In addition, RATA results show extractive analyzers are better than in-situ monitors. Conclusively, the results suggest that the EPB should conduct the OPA and RATA on elder instruments, and conduct the CGA randomly in order to get better air quality assurance in the future.
