This study was to build the database by collecting the results of legal leak test and self-test conducted by the owners of soil contamination facilities at soil-related specialized agency to grip objective status on soil contamination facilities and evaluate classification results. The results of the study showed that the unsuitable rate of business unit is 53.6%, the business with leak that could cause actual pollution is 25.7%, the unsuitable rate of the voluntary self-test is 57.3%, that of the compulsory inspection is 17.2% depending on the test motivation, that of the direct-test is 58.9%, and that of the indirect-test is 22.5% depending on the test methods. There was a significant difference between the test motivation conducted and the test methods applied. From the results of the unsuitable reasons obtained we could assume that about 20% of the whole target tanks became potential sources with natural defects occurred when such tanks were made, and 2.2% of the whole tankers examined that persisting period was caused by progressing corrosion below the minimum thickness.
This study was to investigate the unsuitable rate of the storage facilities, the changes in corrosion process over time after installation according to the status, the time to install the facilities, years elapsed after facilities installation, inspection of methods and motivation, and so on, based on the results of the inspection at the petroleum storage facilities conducted by domestic soil-relate specialized agency to derive optimal management plans which meet the status of soil contamination facilities. The results showed that the facilities more than 5 years after the initial leak test at the time of the installation need to be inspected periodically by considering costs of leak test and remediation of polluted soil. The inspection period can be decided by cost and leak test methods showing discrepancies for the results obtained from individual test whether it was direct or indirect. To compensate these matters, we suggested that the direct inspection method on regular schedule is recommended. On the other hand, the inspection can be voluntarily completed to ease burden of the results by inspection or equivalent level to this inspection method. Also, it may need improved construction supervision and performance test system to minimize the occurrence of the nature defects in installing the facilities as well as the upgrade program for the facilities during intervals of inspection period.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
