The Continuous Emission Monitoring System (hereinafter referred to as “CEMS”) of air pollution for stationary sources applied to monitor the emission state of stationary sources and surveyed the situation of air pollution control large-scale stationary sources of air pollution. It shows the advantages of immediately controlling on pollutant emission and operating performance of air pollution control device. The agency in charge can immediately confirm if the emission concentration fit the emission stander, the instantaneity and accuracy of CEMS are superior to analysis-data regularly, CEMS could be the calculating basis of Air Pollution Control Fees (hereinafter referred to as “the Fees”). In order to ensure the accuracy of monitoring system and strengthen the management mechanism, the major tasks in this year include: 1. assisting EPA to revise relevant rules and regulations of CEMS; 2. enhancing the nation-wide work of auditing and consultation of CEMS and strengthen the CEMS data quality of public and private premises; 3. establishing the EPA CEMS information integration system and accomplishing the OPEN-DATA assignment; 4. examining effectiveness evaluation system and supervising the execution of EPBs. By enforcing the CEMS audit of public or private premises, that included the CEMS system and regulation audit of public and private spaces for 12 stacks, signal alignment check 10 stacks and the standard gas concentration detection check for 5 stacks, relative accuracy test Check (RATA) check assignment 5 stacks and NO/NO2 conversion test audit 5 stacks, to strengthen the CEMS guidance and assistance and audit work and feedback the problems of practical operation to the management level. To understand the CEMS business execution performance of the local environmental protection bureau and known the questions of management layer for 17 local environmental protection bureau. We integrate the execution of present CEMS law and strengthen the measures of against fraud on management layer and increasing the monitoring data quality, the results feedback to the draft of CEMS law revised. That included to increasing the Data Acquisition and Handling System (hereinafter referred to as “DAHS”) norm, such as to enhance the management of DAHS program, revising the way of monitoring data calculation, the determine principle of data identification code and the percentage of effective monitor hours per season and so on. We estimate to add the management model of CEMS maintenance into CEMS law draft for making sure the monitoring data correction and effectiveness. Besides, through the estimate the draft of the 5th CEMS announcement and monitor item (particulate matter mass concentration, heavy metal and mercury) to probe into the feasibility of broaden the scope of regulation as reference resources in future.   To carry out the CEMS regulation informatization indeed, setting up the auto information transmission system of CEMS management which can integrate the nation-wide monitoring data and good for data application, to tie-in the CEMS open data, we analysis CEMS data controversial issue of the No. 6 Naphtha Cracker Complex (Mailiao) of Formosa Petrochemical Corp., and assistant EPA to deal the case study, audit and clarify some facts of 2 factory 4 stacks of the No. 6 Naphtha Cracker Complex (Mailiao) of Formosa Petrochemical Corp.
