dc.description.abstract | The constructions of gas station in early Taiwan are not standardized, which result in a lot of poor quality gas station. Plus, most of the gas station owners are lack of the concept of gas leaking prevention, which leads to many serious contamination incidents. Once the underground storage tank is polluted, gas station owners usually face enormous recovery cost and operational loses. Therefore this research aims to investigate the difference between underground oil tank and oil tank stored in the basement through four different aspects including: economic cost, construction techniques, oil tank management and environmental impacts of the two methods. In addition, this paper also discusses the possibilities and implemental strategies of oil tank and pipelines in the underground.
According to the recent oil tank leaking data, the contamination accidents of underground oil tank outnumbers the oil tank stored in the basement. The financial loss and cost of underground oil tank are also much higher compare to the oil tank stored in the basement. From the economic cost and benefit analysis, it’s possible to reduce costs of recovery fee, time spend on recovery process and the risk of re-contamination through prevention management and planning of the oil tank and the pipelines in the early stage.
From the perspective of construction techniques in reducing the gas station leaking accidents, oil tank in the basement can overcome the restrictions of geography characteristics in the recovery process. A good example is the LPG gas station in the basement, oil tank in the basement is feasible in terms of construction, construction safety, fire control, hazards precautions and other relevant design and facilities.
Nevertheless, oil tank in the basement can prevent contamination and avoid second-contamination caused by lack of oil pipeline indications from the perspective of environmental concerns.
In terms of the legislations, oil tank in the basement is a more practical option as it’s easy to implement and can reduce management costs for both the government agencies and gas station owners. Under the current legislations, environmental agencies should not only supervising on the oil tank in order to make gas station owners become more self-managed, agencies should also play the role in channel the safety design of petrol-chemical stations to the infrastructures of the gas stations. Gas station owners can gradually implement oil tank in the basement as the oil pipelines become obsolete and need to be replaced.
Prevention of oil contamination occurs through oil tank and pipelines in the basement are cost effective compare to recover work after the pollution has already occurred. This finding can provide gas station owners to include infrastructure design in constructing new or refurbishing gas stations. In addition, this concept can also apply to other dangerous goods that can be stored in the underground and prevent pipeline pollutions. | en_US |
