This project begins from 94/3/16th, estimating execution to 94/12/31st. The goal is to assist the Environmental Protection Bureau of Pingtung County (EPB) to propel the emergency measure of local air quality deterioration, assisting the Kao-Ping Area cleaning treaty action committee and the coordinate EPB relative inspection work and the material provides, and assists to propel the investigation when air quality is worsen. The terms including (1) establish air quality worsening notification system; (2) grinds subscribes and carries out the air quality to deterioration in accordance to the measure;(3) assistance public and private place to establish the reports and revises all levels of air quality deterioration controlling project; (4) reinforcing the air pollution accident cooperation and the technical drilling in Pingtung County small region, Holds the general staff character of the EPB; (5) coordinating EPB correlative data report and assistance copes the conference and so on five major terms. This project work achievement elaboration as follows:
1.During the execution, Pingtung County actually has the air quality deterioration altogether 60 days, the proportion were 55 days of O3 and 5 days of PM10. As the reason of Pingtung County is beneath Kao-Ping Region and the effect of climates that cause pollutant not easy to diffuse. There O3 pollution were much worsen around the Pingtung and Chaozhou inspection station.
2.The environmental protection Administration (EPA) Supervises Department to issue 41 days deterioration forecasts, and 20 days that actually occurred, index pollutant was O3. Patrolling work in accordance to deterioration forecasts, each project coordination carries on is connected each control work And the regular checks does an inspection to reinforce the guard system. This year investigation was not only carried on the inspection station based various pollutants by each specify project but also to regard investigation work realization or not, also enhances the control process. Regarding has not reported, or reported situation was not cleared, the request is responsible for the special case plan to provide essential elaboration. Ratio of the various special projects reported investigation work achievement surpasses 70%.
3.This project picks PSI value of Pingtung, Chaozhou and Hengchun inspection station as the deterioration index. The inspection stations judge every day by each hour index pollutant PSI value. When PSI of PM10 >95 or PSI of O3 >85, at once transmits the news brief to inform various special project carry on the investigation work. And asks the company work place coordination to take control measure.
4.According to the “Air Quality Serious Deterioration Control treaty” and based on the EPB’s local characteristic. Revising "the region air quality deterioration system measure" draft for Pingtung County.
5.20 major sources was been selected initially based on each kind of pollutant as first investigates the object when the air quality deterioration occurred, and following should subscribe the suggestion resources list of "the all levels of air quality deterioration control system plan".
6.Establishes the small region air pollution event process system. The content contain the consultation, the notification, the disaster relief, the medical service, the investigation and the environmental monitoring and so on, and union county government office original disaster strain system, Reinforce overall capacity. To considerate EPB authority and under the long-term control condition understood to the public and private place environmental protection service that emphasis in disaster relief consultation, accident investigation and environmental monitoring work, After again coordinates this county cope system that already have like the fire prevention, urgent medical service, poisonous disaster and so on, establish overall disaster relief system in this county.
7.This project was carried on the atmospheric sampling analysis inspection. gravel heap site, agricultural waste open-air burning source in Pingtung County and places such as Pingnan industrial district, Demonstrated according to the sampling analysis result that：(1) This county sand and crushed stone special area carries on when the river bed sand and crushed stone mining work when and periphery gravel heap site in normal work condition, Particle size of peak distribution in atmosphere was between 3.2μm and 5.6μm, and gets higher proportion of thick particle（between 2.5μm and 10μm）when the mining work carries on. (2) The particle size distribution was between 0.56μm and 1.0μm when open-air burning of waste branch and straw, mainly thin particle, and the measured value higher if burning place nearer. (3) In Pingnan industrial district atmosphere, SO2 concentration in the daytime was higher 5.5 times than that at night. The density change of NO2 and NOx was more relative to the traffic flow. O3 value was between 18.6ppb and 110ppb.The concentration obviously rises after the noon then reaches the maximum at 2 PM afternoon. THC concentration range was between 1.06ppm and 14.5ppm.NMHC concentration range was between 0.05ppb and 2.54ppb and CO concentration range was between zero and 0.985ppm.
