Vale (NYSE: VALE) is asking regulatory bodies in Brazil to extend a deadline for removing 23 upstream tailing dams located in the state of Minas Gerais due to a "technical impossibility" to meet the current February 25 deadline.
Upstream dams are the type of the structures that 2015年にマリアナで失敗しました, and Brumadinho in 2019. The first disaster killed 19 people and the second accident 270人が死亡した.
Vale, which owns most dams related to iron ore production in Minas Gerais, has eliminated four upstream dams in the state since 2019 and another three in Pará state, where a total of 30 belong to the company.
リオデジャネイロ-を拠点とする鉱夫は、上流の尾鉱ダムをすべて撤去することに引き続き取り組んでいると述べ、年末までに40％、2029年までに90％を撤去すると見込んでいます。
Full decommissioning, however, won't be reached before 2035, it said in a 地元メディアが引用した声明.
The iron ore producer 先月言った it plans to spend about 9 billion reais (1.65 billion) this year on reparations related to the Brumadinho dam burst.
3年後、ほぼ40億
2019年以来、同社は社会的および環境的損害の賠償と補償に約180億レアル（約36億レアル）を費やしたと述べた。
さらに、12人近くの000人がValeと民事および労働補償契約を締結し、26億レアル以上の支払いがありました。
Last year, the mining company signed a full reparation agreement with the government of Minas Gerais, the state and federal public prosecutors and the public defender's office that governs ongoing actions, and which ended collective legal actions. The individual agreements, on the other hand, are being carried out separately.
In January 2020, state prosecutors 充電されたFabioSchvartsman、元鉱夫の最高経営責任者、およびダム決壊のために殺人をした他の15人。 後に裁判所は、事件は州裁判所ではなく連邦裁判所を通じて進められるべきであると裁定しました。
There are other upstream dams in the state owned by companies like CSN, Gerdau and ArcelorMittal, according to records of the National Mining Agency (ANM) and the Minas Gerais government.
This type of tailings has long been banned in earthquake-prone mining countries such as Chile and Peru because they are susceptible to damage and cracks. This makes them nearly 2倍不安定 as the average mining waste facility, 研究は示しています.
While Brazil is not as earthquake-prone a nation as its western neighbours, it's been shown that even small seismic activity can affect tailings dams such as the one near Brumadinho.
