Five objectives in the project execution:
1. to revise the standard operating procedures of CEMS instrument checks and quality assurance
2. to review and audit the monitoring facilities and monitoring data accuracy in the factories installed with continuous automatic monitoring equipment
3. to help check whether the connection data specification is corresponding to "stationary sources of air pollutants CEMS management approach" in order to ensure the accuracy and completeness of the data
4. to haveCEMS system on-site evaluation and regulatory compliance inspection operations
5. to maintain the database system functions and communication environment
Upon completion of this project bargaining, all the tasks were on the go according to the working methods and the definition of the content and scope stated in the service proposal.
Currently the manufacturing procedures of the first controlled connected row of the flue pipe include: boiler power generation procedures, cement manufacturing procedures and the electric arc furnace steelmaking procedures. There was a total of 21 factories, 64 times of the flue; the second batch of connected flue tube are waste incineration procedures with five factories and 14 times of the flue; the third batch is the boiler power generation procedures (80 to 130 tonnes/hour), chemical manufacturing procedures and iron primary smelting and sintering procedures, with a total of 12 factories and 36 times of the flue and self-connected four factories with 10 times of the connection. In Kaohsiung City, there is a total of 31 public and private factories with 124 times of the connected flue.
Till 2013/112/31, Statistics showed that each annual work tasks have been done as scheduled, priority check fell on those who had poor results from the recent years of the past. The working schedule is shown on Table 4-1, and the summary of the audit work schedule can be seen on Table 4-3.
In the pre-operational aspects, according to the review of management practices and relevant regulations, the revision of the CEMS checking and quality assurance operating procedures have been completed the submission, respectively on May 18,2012 and January 30, 2013.
Monitoring equipment function checks aspects:
In 2012, it have been completed the relative accuracy test audit with 32 times of the flue, with the completion rate of 100%; except P001 HCl is not qualified in the central area; the remaining testing items are qualified all at the rate of 100%. As for the offset correction factor (BAF), the occurrences of sulfur dioxide are at a higher rate of 13%, the error correction opacity performed in the check of the flue with 30 times of the flue with the completion rate of 100%; the low, medium and high range of pass rate is all 100% with the majority less than 1%; the standard gas check executed is of 35 times with the completion rate of 100%, and each measuring items are all qualified with the error mostly less than 5%; nitrogen dioxide checks are carried out for 26 times with the completion rate of 100%, and overall conversion rate of 94.38%. Compared with the average of 91.11% in 2011, it has been upgraded by 3.27%.
In 2013, the relative accuracy test audit has been done on 38 times of the flues with the completion rate of 100%. At the present stage, the qualified rate is all at 100%; as for the Bias Adjustment factor (BAF), the incidence of the discharge flow rate was higher (34%), the opacity correction checking has been done on 38 times of the flue with the completion rate of 100%; the low, medium and high range pass rate was 100% with the error less than 1%; the checking and implementation of the standard gas was 45 times with the completion rate of 100%; each measuring items are qualified, and the error was mostly less than 5%; nitrogen dioxide checks have been carried out for 22 times with the completion rate of 100% so the overall conversion rate was 90.92%; as for the factories with poor conversion rate, after the checking, they are suggested to regularly test on their own. During the poor conversion-rate period, the related supplied should be replaced. As for the flue checking of BAF, manufacturers should pay attention to the condition of systematic bias.
Monitor audit aspects:
In 2012, it has completed a total of 26 sets relative accuracy test audit and supervision and 20 sets of opacity oversight audit. In 2013, 30 sets of relative accuracy test audit and supervision; 25 sets of opacity checks. Because the monitoring the audit was done by the factory itself with supervision to confirm whether the factory actually executed in accordance with regulations. Currently, they are all in compliance with the requirements .
Monitoring data quality aspects:
Monthly regular review, the completion journal and monthly journal and the valid monitoring hours percentage statistics. Some factories have lost their data due to the hardware and software anomalies in the data processing systems or abnormal power failure. Currently, the transferring rate of daily and monthly data all have reached 100%. According to the monthly report, the majority of public and private factories have done correction according to the monthly review results. The monthly deletion has a declining tendency. The effective rate in every quarter all reached more than 85%, except the first quarter of 2012 of Formosa in Renwu P751 and in the first quarter in 2013 LongQing Steel lower than 85%. The rest of the factories were more than 85%. The plant uploaded daily report has been checked daily. Currently, there weren’t any exceeding the the control times and statistics collected from every factory’s emissions have continued. Except the over emission of P008 NOx in CNPC Dalin by more than 10%, the rest are all in compliance with the license; the overall emission trends haven’t shown any cases of abnormal situations given by EPA announcement .
On-site evaluation operation aspects:
The on-site evaluation works have been done in 15 factories in 2012 and 2013 respectively with the completion rate of 100 %. Every factory has been informed of the relevant shortcomings and the factories’ feedback has been compiled completely. The shortcomings in 2012 have been followed up and the improvement rate is 100%; the shortcomings in 2013 are also being followed up as factories’ scheduled.
Regulatory compliance inspection aspects:
There were 51 times and 55 times of flues audit operation completed in 2012 and 2013 respectively. As for the their shortcomings, the follow-up counselling works have been done continuously. To confirm that the factories improved the situation, the work team from time to time traced the follow-up operations to enhance the connected factories’ quality assurance and quality control, increasing the accuracy and reliability of the connected information. However, the places needed to be improved all lied in the personnels are not familiar with the job and then correction delayed. In these two years, the item not inconsistent is the lack of efficiency 85% in Formosa Plastic Corporation Renwu factory and Long Ching Steel Enterprise Co. respectively. In the future, these two factories should be paid attention to.
Management administration aspects:
In the past, there used to be manufacturers trying to write a program to avoid the checkups. Therefore, in the checking, a high concentration gas monitoring instrument was used to test if the value could be showed normally when testing something exceeding the emission standards. Currently, factories were functioning normal and it displayed the value exceeding emission standards .
Recent management effectiveness:
These three years, on the CEMS management, in addition to the items specified in the regulation, there have been some items added such as the conversion rate of NO2 checks (target 90%) with a high concentration of checks (emission check standards) as follows:
1. The conversion rate of NO2: From 2011 to 2013, the conversion rates were 91.1%, 94.4 % and 90.2% respectivel; the overall average of all reached the expected goal. In 2013, due to Taipower Nan Huo and Taipower Xingda’s bad check results, it made the overall conversion rate decline. Currently, Taipower has completed the improvements. Those factories without improvements will continue being followed up and included in future priority inspection list.
2. high concentration checks: To confirm that the monitoring instrument can display the over-limit values, we have been using the over-limit emission gas to do it. These two years, the monitoring instruments have been functioning well displaying the over-limit values.
Maintenance connection functions and communications environment aspects:
In order to make the EPA host system run smoothly, Envimac environmental solution provider has done maintenance and backup to the host functions and file conversion modules to improve the availability of information and enable the connection system to work more perfectly.
