Sochi, host of the 2014 Winter Olympics, faces an environmental disaster because there are no legal garbage dumps, Vedomosti reported Tuesday, citing a report by the Audit Chamber.

The area is expected to produce up to 5 million tons of construction waste ahead of the Olympics, but the only garbage dump currently in operation was ordered to shut down in 2006 because it failed to meet environmental regulations, the report said.

Trash-burning facilities that could provide relief will not be built until 2013, while sewage is being dumped into the Black Sea not far from the shore, the chamber said.
