Currently, all waste is disposed of at a site near the village of Loo. However, the dump was officially closed in 2006, chamber auditor Mikhail Odintsov said.

The dump frequently sees blazes and waste pollutes the waters of the Pitkha River, which runs into the Black Sea, another member of the chamber said.

If the situation remains unchanged, during the peak of construction there will be no place to legally dispose of some 5 million tons of waste.

The situation could be changed by the construction of waste processing plants, but they won't be built before 2013. Responsibility for their construction lies with companies belonging to Russian tycoon Oleg Deripaska.

Seventy-two out of 242 Olympic facilities planned to be built in Sochi are already under construction.

The Sochi Winter Olympic Games will open on February 7, 2014.
