"The information integration project for air pollutants control in outlying islands’ industrial zone" this year has started since May, 09, 2014. The main tasks of the project are the following. Firstly, securing the existing or potential Volatile Organic Compounds in the industrial zone of high pollution and transport conditions of local air mass, to adopt the precautionary strategies effectively. Secondly, employing material information of the plants in the industrial zone to establish the fingerprint information of pollutants, and adopting Chemical Mass Balance;CMB) model to analysis pollution sources of each receptor point. Furthermore, the project continues updating, maintaining and expanding the function of the existing environmental monitoring system. Besides, self-management of air pollution and reduction plan of each company and the results tracking are integrated. Finally, air pollutants checking and controlling plan of outlying islands industrial zone are provided to Environmental Protection Bureau Yunlin County for their education and technical training.
The implementation results of this year project are as follows:
1. Investigating the Volatile Organic Compounds
The industrial area of VOCs sampling in Sixth Naphtha Cracking Plant had been tested 72 times, A zone (Haifeng area) pollutant concentrations range between 205.8 and 5004.61g / m3, and B zone (Mailiao area) pollutant concentrations range between 201.14 and 3938.62 g / m3. Through the results of the total concentration graph in the two main areas and the ground wind field graph, the influence of the 9 sampling points in each area by the wind direction and velocity can be derived. The high concentration sampling points were found in the downwind position mostly. It is not only impacted by the pollutants from upwind position, but also the pollutants from the nearby plants. The pollutants not easy to accumulate in high wind speed therefore the pollution concentration relatively low.
2. Chemical Mass Balance receptor model (CMB-8.2) analog
We adopted CMB-8.2 receptor model to stimulate VOCs contribution ratio of nine sampling points in the industrial area of off-shore Island. CMB-8.2 simulation results show that the main source of pollution contribution of A zone(Haifeng area) has four factories, namely synthetic resin or plastic process of ChangChun artificial plant (A9 contribution accounted for 74%), synthetic phenol plant (A9 contribution accounted for 79.8%), styrene third plants (A1 contribution accounts for 54%) and n-butanol plant (A5 contribution accounts for 50%) ; the main source of pollution contribution of B zone (Mailiao area) has three factories, namely epoxy resin plant (B3 contribution accounted for 33.4%), high density polyethylene plant (B4 contribution accounted for 36.5%) and a polystyrene plant (B8 contribution accounted for 40.2%).
3. The further checking and testing by the scholars and experts
There are four sessions of further checking and testing by the scholars and experts this year. The target company in the first session is M01(OL-2 department), M02(OL-3 department), M10 of Formosa Petrochemical Corporation Mailiao Branch on June 12-13,2014. The target company in the second session is M01(PHENOL department), M02(PHENOL department), M14(ARO-2 department), M15(ARO-2 department), M16(ARO-2 department) of Formosa Chemicals ＆ Fiber Corporation Haifong Branch on October 13-14, 2014. The target company in the third session is MA1(MMA department), M91(C4 department), M92(C4 department) of Formosa Plastics Corporation Mailiao Branch on November 24-25, 2014. Finally, the target company in the fourth session is M01 of Dairen Chemical Corporation, M01 of ChangChun Plastics Corporation, M01 of ChangChun Petrochemical Corporation on November 27-28, 2014. There are 184 suggestions from the committee members in total, including 76 suggestions of license checking (41.5%), 45 suggestions of emissions checking (24%), 21 suggestions of air pollution fee checking (11.5%), 42 suggestions of VOC regulations checking (23%).
4. Updating and maintaining the central monitoring database integration system of outlying islands industrial zone.
Base on the different properties of each database, different frequency of regular updating are applied. Moreover, proactive notification function has been built up in the central monitoring system. And in the central monitoring system functional expansion, build proactive notification platform capabilities(air quality, excess of meteorological stations, CEMS and FLARE flow). Besides, the digitalization of checking form has also been set up, including the following:
1. Air pollution inspection records of public and private premises to inspect records sectors; 2. On-site checking records of stationary pollution source.
In order to offer greater convenience to citizens, we had erected a 42-inch electronic billboard for teachers and students to check the real-time air quality information (PSI, SO2, CO, PM, etc., and the standard value).
5. Integrating the self-management air pollution improving state of four main companies in Sixth Naphtha Cracking Plants
In the two pollution control and review secessions (on June /8 and November 26), the companies in Formosa Plastics Group Industrial Zone replied the updating status to previous comments and conclusions on the self-management air pollution reduction plan or the agreed affairs. There are 240 comments and conclusions in total from the previous review meetings. 190 of them are completed. The others are under processing. VOCs are reduced 20.85 tons by self-management and the investing amount is NT$35,041,000 this year. The reviewing and tracking of the pollution reduction and the improving state will be continued through the meeting in the future.
6. Providing education and technical training of existing air pollutants check
The first training session of this project was held on June 16, 2016. The purpose of this training was to introduce the operation of "emergency response system”, under the framework of the environmental monitoring system of outlying island industrial zone. Via the system, information and state of the plants can be controlled quickly during an emergency. The second training session was held on November, 18, 2014. In this session, experts and scholars were invited to talk about how topography and monsoon impact on basin aerosols.
7. Assist in emergency incidents occurring in outlying island industrial zone.
We have assisted in emergency response in outlying island industrial zone for ten times, including reporting back related information and writing press releases, namely on May(one incident), July(two incidents), August(4 incidents), September(one incident) and October(two incidents). We aid EPA to grasp the relevant information and control the on-site conditions in the emergency response process.
