Att.:    Mr. Guilherme Rocha Lopes

Business Monitoring Manager 2

 

 

Ref .:   Official Letter No. 24/2019 / CVM / SEP / GEA-2, dated February 6, 2019, requesting clarification on the Notice to the Market.

 

 

COMPANHIA SIDERÚRGICA NACIONAL ("CSN" or "Company"), in accordance with the above-mentioned letter, which contents of the query are transcribed below, present the clarifications requested:

 

"We refer to Official Letter 20/2019/CVM/SEP/GEA-2, as well as to the Notice to the Market of 02.05.2019.

 

2. With regard to the decommissioning and subsequent revegetation of the Casa de Pedra Dam, CSN stated that "The decommissioning and subsequent revegetation of the Casa de Pedra Dam are natural consequences of dry stacking process; however, it is a long-term project and process, so it is not the case of disclosure of material fact at this time. "

 

3. On this matter, we request that you make it clear whether the Company intends to carry out the decommissioning and subsequent revegetation of the Casa de Pedra Dam, detailing the main, albeit preliminary, information regarding estimates of deadlines and amounts involved."

 

The Company clarifies that decommissioning takes place in several technical stages and is a natural consequence of the dry stacking process, already initiated by CSN Mineração in 2016, when it installed the processes of magnetic separation and filtering of tailings from the Casa de Pedra Dam. However, it is premature to disclose any deadline/value, albeit in a preliminary way, since the next steps are still undergoing technical review due to the complexity of the entire process.

 

CSN Mineração strictly complies with applicable environmental legislation and has all valid environmental licenses for the disposal and management of tailings in its dam.
