This project’s implementation period started from March 1st, 2009 to February 28th, 2010, for a period of 12 months. Main work contents included: the checking of volatile organic liquid storage tanks in Taichung Harbor area, the inspection and guiding of volatile organic liquid storage tanks, the assessment on volatile organic liquid storage’s control equipment, on-site testing of the control equipment, and the planning and drafting of relative emission standard and control specification plan, for a total of 24 tasks. Up to February 28, 2010, all the tasks have been completed and the progress chart was detailed in this final report’s Table 1.3-1 in Chapter I.
According to results obtained from the four times of checking, in 2008 the total operating capacity of volatile organic liquid in Taichung Harbor West Pier was 3.56 million kiloliter and the emission checked was 549.9 tons. In 2009, the total operating capacity was 2.84 kiloliter and the emission checked was 429.5 tons. The significant drop in emissions mainly was because the operating capacity was reduced due to recession and also partial factories stored more low volatile matters instead of high volatile matters. Meanwhile, for enhancing the compilation of warehousing business’s dynamic information, this project constructed a database for volatile organic liquid storage tank in Taichung Harbor area to carry out analysis on all kinds of checks and claimed data. There were unqualified cases found in both two regulation compliance checks conducted this year. Such unqualified issues mainly were because activated carbon absorption facility did not operate in accordance with regulations and also factories had incomplete tank cleaning record. Those were guided for improvement and the improvement has been completed as well. In addition, as for businesses that have reached the scale to apply for the permit but have not yet submitted the application, after handing the cases to authorization project for follow-up tracking, those businesses all submitted permit application to Environmental Protection Bureau. As for audits and inspections, 2400 components were inspected and did not find any unqualified cases; three perimeter detection tasks in cargo handling process were carried out and it did not find any one exceeded stationary source’s emission standard. Besides, for enhancing warehousing industry’s self-management ability in the harbor area, the team drafted a self-management plan to help industries carry out self-management tasks and also provided guidance and interviews to enhance industry’s pollution inspecting and preventing behaviors. This year, one other focus was model scale biofilter on-site test. After the completion of preliminary works, which included control equipment’s assessment, 2 week continuous sampling task, and the lab testing work, in September the model scale biofilter test was started and carried out testing tasks up to now. The test results showed that biofilter effectively improved the previous inefficient control problem by active carbon, and the elimination rate was around 85%. In addition, it’s not necessary to replace active carbon. Thus, the operating cost was reduced significantly and the problem of secondary pollution by wasted active carbon was also solved. The test results can serve as references for industries in improving control facilities.
Besides above-mentioned tasks, this year we also held two times of expert consultation conference. At the 1st conference, professional and scholars were invited to provide control related suggestion, and the 2nd time, professionals, scholars, and industries were all invited to discuss issues relating to designated drafts that have been published. Also, the Regulation guidance conference was held on July 17, 2009, and the main contents included the illustration of related control regulations, introduction to Taichung Harbor storage tank’s database, and providing real examples on biological treatment of storage tank’s VOCs emissions to enhance industry owner’s cognition in related regulations and understanding of pollution control technology. On February 1st, 2010, a result presentation on the tests of biofilter experiments was held to explain the effects to factory owners. On February 24th, an out-of-county control technology related demonstration trip was held to visit the efforts in air pollution control and the effects at No.6 Naphtha Cracking Complex in Yunlin.
Further, in order to promote project executors’ professional abilities, in 2009 this project held 8 education training sessions; the training topics included the illustration of laws and regulations, application of the database, and key issues in testing equipment components. Those were believed to have beneficial results in executing project personnel’s tasks.
This year, in order to improve the emission of pollutants by west pier’s warehousing businesses, besides carrying out all kinds of inspection tasks and drafting related control specifications following warehousing industry’s characteristics to enforce more stringent control, the project also tried to use biofilter to improve current pollution control facilities’ control efficiency and obtained good test results. Thus, in the future, it is expected to put into practical use and for a further step to improve warehousing storage tank’s pollutant emissions.
