SAO PAULO, Dec 30 (Reuters) - Brazilian miner Vale

said on Monday it reached an agreement with local

authorities under which it would pay up to 11 billion reais

($1.78 billion) to renegotiate the contracts of two railway

concessions, the firm said in a securities filing.

The Brazilian government has been aiming to remove discounts

given to rail companies by the previous administration when they

received an early renewal of their contracts.
