Evraz may have to shut one of its three plants until a new facility to treat waste water is built. The Federal Agency for the Inspection of Natural Resources Use will ask a court to order the closure of Novokuznetsk Iron & Steel, the regulator said in a statement.

The company does not expect to complete the waste facility until 2010. "Documents on the waste disposal program are in the process of being agreed upon by state structures" Novokuznetsk said in a statement Friday. The mill has been disposing waste under an accord with the local authorities since 2003, it said.
