As London and post-Koyto protocols presumably affect emission of organic waste in Korea in 2012, appropriate treatment of organic waste becomes very important. Organic wastes are regarded as non-point pollutants. It has been criticized that direct emission charges on the emission of non-point pollutants are not effective due to the high uncertainty in the relationship between pollution sources and pollution levels. This study suggests indirect emission charges on production of livestocks or consumption on foods. Furthermore, it is assumed that revenue from the emission charges will be recycled to support biogas production. Biogas can be fueled to produce energy. In order to evaluate potential economic and environmental impacts of recycling the indirect emission charges on organic wastes, a static CGE model was developed. Simulation results of emission charges on the production of livestock show that livestock, agriculture, and food industry will confront relatively high burden while emission charges on consumption of food will affect more broadly and consumers will suffer more. Production charge on livestock sector will lead to higher reduction in GDP and total expenditure relative to the consumption charge. GHGs reduction effect was higher for the consumption charge relative to the production charge. Synthetically, consumption charge on food sector is more desirable as an alternative charge for the emission of organic wastes.

Since the OPRC-HNS Protocol entered into forced in the June of 2007, the potential effects on industrial circles are encouraged to be analyzed according to the obligatory regulations listed in the Protocols. This study was conducted on the quantitative analysis of the possible effect on the industrial circles if Korea accedes to OPRC-HNS Protocol. In spite of any burdens caused by keeping "accident emergency program memorandum" and performing "education and any training program for the crews", potential decrease of insurance fee is in possibility provided it follows. In addition, the oil refinery and petrochemical industries may also have burdens for potential costs for acquiring any materials including equipments and fees for education and training related to HNS. However, minimizing any costs by swift response against accidents would be big advantage that comes with paying of small amounts of expense by international convention related to HNS.

The purposes of the paper are to estimate welfare change from water quality degradation by using contingent valuation method in Namdae stream of Gangrung and identify what factors of Namdae stream are important to Gangrun citizens. The study results show their total WTP per year and per household, \117,040 to improve Namdae stream quality from grade 3 to grade 1, including monetary WTP \87,502 plus opportunity cost of volunteering time for protection campaign, \29,538. The amount of total welfare change from water quality degradation based on the total WTP estimated above is calculated to be \27 billion of which the amount, as a sort of damage cost from water quality degraded, is so huge. All projects and policies related to natural environments, therefore, should consider both indirect and direct effects from them because natural environments have the irreversibility once degraded or deteriorated and would ultimately be influential on humans, both current and future generations, with tremendous amounts of time and costs beyond our imagination.

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.
