A scheme for allocating marine pollution costs - a case study of Izmit Bay area

This study determines what should be the contribution of each firm to the cleaning up cost of the eastern part of İzmit Bay. The total initial investment of cleaning up the eastern part of the bay consists of: the costs of the inciniration plant, waste water purification plant, collector, and solid waste depositing plant. As the marine pollution is considered in this study, calculations are based on the initial investment costs of collector and waste water purification plant. At the first step, establishments are ranked and scaled with respect to their daily total discharge in volume. After this initial stage two models are designed to determine the contribution costs. In the first model costs are determined for each establishment, where as, in the second model costs are determined per parameter for each establishment. The results indicate that the second model is more accurate since, it is possible to be more specific in cost allocation.
