OSAKA — A mediation plan unveiled Friday aimed at settling a dioxin contamination problem that occurred near an incinerator in Nose, Osaka Prefecture, would have the incinerator's maker and the plant operator pay a total of 750 million yen to local governments.

Osaka Prefecture's pollution examination committee unveiled the plan, which calls for Mitsui Engineering & Shipbuilding Co. and its subsidiary that operated the plant to pay the sum.

If the plan is accepted by all parties concerned and formally signed July 14, it will be the first case of dioxin pollution in which the builder of the responsible plant assumes a financial responsibility for the contamination. It will also put an end to the 26-month old dispute.
