This project is a successive regulatory plan, the main purposes are to control the emissions of volatile organic compounds (VOCs) according to regulations of VOCs announced by Environmental Protection Administration (EPA), carry out the regulate operations in Taoyuan refinery of CPC corporation, and assist the installation and investigation of continuous emission monitoring system(CEMS) in the correctness of data transmission to understand the characteristics of pollutant emissions and improve air quality in Taoyuan city.
The execution of the project was scheduled from 2013/03/24 to 2014/03/23 with a total of 12 months. The progress in implementation of each individual work, included the control of VOCs, pollution reduction, inspection of factories, pollution control of Taoyuan refinery of CPC corporation, supervision of periodic detection ＆ online reporting review, renewal or maintenance of CEMS for compliance with CEMS regulatory, and handling regulatory seminars etc., were executed according to the schedule of the project. All the progress of the work complied with the contract requirements, the abstract of achievements were shown in table 1.4-1 and 1.4-2.
The key works of the project in this year are including:
(一). The control of volatile organic compounds(VOCs)： A total of 227 special industry manufacturers had completed their declaration and inspection. In addition, there are 4 potential manufacturers with improvement and reduction pollution have been approved, the total reduced 24.558 ton/year.
(二). Inspection of stationary pollution sources：The total 107 samples are completed in stationary source、ambient air pollution and stationary sources involved sulfur content. Out of 71 samples in stationary source, 33 samples are not in accordance with emission standards, the failure rate is 46.5%.
(三). The function check of gas station vapor recovery：The gas station oil ratio investigation of 61 times are completed. To compare the gas station oil ratio between 2013 and 2014, the mean pass rate upgrade from 88.0% to 91.5%。The number of defective gasoline nozzle are 54, however, after improving the gasoline emission reduced 17.96 ton/year.
(四). Pollution control of Taoyuan refinery of CPC corporation：(1)The forward looking infrared (FLIR) or flame ionization detector (FID) in for leak screening and testing of equipment components, the leakage rate of processes in a subsequent quarter reports have shown significant decreased tendency from 0.45% to 0.28% through inspection and control in 2013 and 2014, respectively. (2) the flares exhaust gas reduction task, the data of gas flux monitoring for 12 flares have been on-line with Environmental Protection Bureau (EPB). The #4 hydrogen sulfide (H2S) elevated flare with exhaust gas recycling has been established in May 2014. The SO2 reduced 12.67 ton/year and VOCs reduced 860.18 Kg. Therefore, the four H2S elevated flare have completely exhaust gas recycling. For another 8 hydrocarbon (HC) ground flare and elevated flare with Flare Gas Recovery System (FGRS) have been work from 2014/06/23；(3) Popular petitions, there are total of 29 air pollution petitions in 2014, mainly due to the plumes from P030 and the increased number of annual maintenance. The related investigation and improvement in P030 are required in MOU
(五). CEMS regulatory： The 32 CEMS inspections are completed and after counseling, the pass rate is 100%. In addition, the 18 RATA inspection are also completed, and comparison of the data between manufacturers' RATA and during the investigation period, the mean value within 72Hr is not greater or smaller than the 3 times standard deviation, the all data quality are good.
The relevant contents in details will be presented in the upcoming sections.
This project extended the investigation in 2014, and remain committed to synchronously combined with advanced instruments for inspection and counseling task. To strengthen the abilities of inspection, based on charging overdue air pollution fee as the incentive for counseling. It can feedback the real pollution situation and implement the licensing system to reach the goal of the 2015 Taoyuan city pollution control project in NMHC reduction.
