volunteers. The company has set up a feeding and medication center available for
animals while in the shelter.
What other actions is Vale taking to assist the animals?
Vale has issued a list of the animals sheltered at Abrigo de Fauna farm and the Veterinary hospital.The company reinforces the ongoing assistance for the animals affected by the dam breach in Brumadinho.
Is it possible to visit Abrigo da Fauna farm?
Yes. The farm can be visited on Saturdays. To schedule a visit, call the Service
Center – 0800 031 0831.
Why is Vale promoting Dog and Cat Adoption Events?
Vale is promoting Dog and Cat Adoption Events aiming at promoting responsible
adoption and giving a new home to the animals currently sheltered at the farm.
Besides that, the event is a great opportunity to promote the reunion of the animals
with those who had lost them. This is part of an agreement signed with the
Prosecution Office of Minas Gerais as part of the Preliminary Agreement (TCP, Termo
de Compromisso Preliminar). For adoption, it is required to submit a copy of the ID
(with photo) and a proof of residence. Each tutor will receive a brochure with
guidance for animal care.
How are the tailings moving?
The tailings that leaked from Dam 1 are concentrated in the Ferro-Carvão stream and
in the confluence of the steam and the Paraopeba river. Because the dam had been
inactive with no tailings being added for approximately three years, the slurry was
relatively dry and did not leak too far.
What measures are being taken to prevent the spread of tailings?
Vale has been building impoundment structures that together will stop the flow of
sediments into Paraopeba river and help cleaning of the river and Ferro-Carvão
Between B1 and the confluence of Ferro-Carvão stream and Paraopeba river, there are
three great impoundment structures (two hydraulic filtration barrier and a dike), as
well as 24 small stabilizing barriers. The purpose of these interventions is to
retain sediment flow to Paraopeba river. Construction works are in progress and
shall be complete by the end of this year.
In addition to these structures, a curtain of metal piles was installed near the
confluence of Ferro-Carvão stream and Paraopeba river. This measure will allow
cleaning of the river stretch where the major concentration of sediments is located.
Since May 27, the flow of solids into Paraopeba river was stopped.
To complement recovery of Paraopeba river, a River Water Treatment Plant (ETAF,
Estação de Tratamento de Água Fluvial) was set up near the confluence of
Ferro-Carvão stream and Paraopeba river. Since May 9, when operations started, until
the beginning of September, the ETAF returned into Paraopeba river 1.5 billion
liters of clean water in accordance with the legal standards defined by the National
Council for the Environment (Conama, Conselho Nacional de Meio Ambiente)
Are these structures permanent?
All structures are decommissionable; they can be disassembled from the moment they
are no longer required for stabilization of the affected areas.
Will tailings be removed from the affected stretch of Paraopeba river?
Since mid-May, Vale has been dredging tailings from the affected stretch of Paraopeba
river. This process is essential for recovery of the river. Dredging removes the
tailings from the silted area of the river. The material removed is stored and
dehydrated in large bags (geotextile bags). The water drained from these bags are
pumped to a treatment plant and returned clean to Paraopeba river. Dredging
activities are planned to continue until 2020, beginning at the confluence of
Ferro-Carvão stream and Paraopeba river, and extending along almost 2km downstream
from this point. It is estimated that between 300 and 350 million m3 of material
leaked from B1 dam is deposited along this stretch.
Dredging is not the only action to remove tailings from affected areas. Since the
breach of B1 dam, tailings removal planning and execution is being carefully
conducted together with the Fire Service.
How are tailings transported and were are they deposited?
A 3.6-km-road access was built where the old rail branch of Córrego do Feijão mine
used to operate. The access is already in use and it is exclusive for construction
works vehicles, especially those used for tailings handling. The road goes from the
bridge on Alberto Flores avenue to the mine. With such action, the traffic of heavy
vehicles has been significantly reduced on local roads, improving road flow, safety
,and comfort for the communities.
It is important to highlight that removed tailings will be inspected by the Fire
Service and, after approval, they are deposited in an area within Córrego do Feijão
mine, previously authorized by relevant authorities.
How does the barrier work?
The sediment control barrier is 30 meters wide and 2 to 3 meters deep. The structure
works as a filtering fabric, trapping solid particles (clay, silt, organic
matter...) that cause water turbidity and change its transparency.
To maintain the anti-turbidity curtains in a vertical position, there are metal
chains at the lower edge (submerged part) that avoid the river flow to force the
curtain to the surface. The flotation element is a cylinder buoy that can be used to
prevent the spread of sediments suspended in water.
How does the Fluvial Water Treatment Station work?
The Fluvial Water Treatment Station (ETAF) has the capacity to treat approximately 2
million liters per hour. The implementation of the structure is part of the Reject
Containment Plan presented by the company to public agencies.
Near the Avenida Alberto Flores‘s new bridge, a curtain of metallic stakes was
installed to contain the tailings. At this point, the water of the Ferro-Carvão
stream is being collected and pumped to the ETAF, where it passes through filtering
and sediment removal processes.
In the ETAF, the water is separated from the solids by means of a settling process
and then passes through the filtration, returning treated to the stream Casa Branca,
another tributary of Paraopeba.
The solids decanted in the sedimentation basin are directed to large pockets called
geotextiles, responsible for containing, storing and dewatering the tailings.
Drained water from these pockets is fed into the installed filtration system. The
solids in the geotextile tubes will be removed and transported to an area previously
defined and authorized by the competent bodies.
This whole process of water treatment is fundamental to significantly reduce the
sediment movement in the course of the Paraopeba river. With the installation of
this system, Vale reaffirms its commitment to mitigate the impacts caused to the
environment and communities as a result of the dam’s breach.
Is Vale monitoring the Paraopeba river?
Since January, Vale has implemented a series of actions to monitor the water quality
of Paraopeba river. Currently, there are 67 monitoring points covering an area of
more than 2.6 kilometers along the river. Almost 3 million water, soil, and sediment
analyses have been performed, checking 393 parameters. In addition to surface water
analysis, samples were also collected at two meter depth. The results compared to
the surface water analysis were under normal conditions. The analysis is being
conducted by four specialized laboratories, involving approximately 250
Since late March, mercury and lead levels are below the legal limits according to
the analyses of the Water Management Institute of Minas Gerais (IGAM, Instituto
Mineiro de Gestão das Águas). But, due to the presence of these heavy metals, the
State Authority prohibited the water withdrawal from river directly. This
prohibition remains as a preventive measure.
Does Vale have any information on the causes of the breach?
The company's efforts are focused on the care of those affected and on the reparation
and development of the municipalities affected directly and indirectly. Vale
reinforces its support for the Civil Defense and the Fire Department, who are in the
area in search of the disappeared. In addition, Vale continues to investigate the
causes of the disruption, but does not t have a conclusion yet about the causes.
Vale is the most interested party in the investigation of the facts and has
cooperated fully with the authorities. Documents and information requested by the
Justice and other institucions have been presented by the company and its employees
in an uncontested way, in collaboration with the investigations.
Independent Committees of Extraordinary Advice ("CIAE") were set up to follow up on
measures to assist the victims and the recovery of the area, to determine the causes
and to reinforce the safety conditions of the dams.
Did Vale know about the risk of a dam breach?
Dam I had all applicable stability affidavits and was subject to an external and
independent audit in September 2018.
Was dam 1 in operation?
Dam 1 was in the process of decommissioning. It had been inactive for about three
years. Consequently, no tailings were being added. It was built in 1976 by Ferteco,
a company that was acquired by Vale in 2001.
Did the breach affect other dams?
The small structures IV and IV-A of the Córrego do Feijão Mine were struck by the
tailings that leaked from Dam I. Dam VI was inspected shortly after the Dam I
breach. It is being constantly monitored by two radars, being one of them every 3
minutes with real-time monitoring.
Is Vale taking action to improve safety in Dam VI?
Yes. Vale is carrying out the lowering of the water level of the VI Dam, through a
pumping system, keeping the structure at the recommended safety level. In addition,
the recovery of the surface drainage system is being carried out.
What are dams?
Dams are structures designed by engineers, used as a reservoir to contain or
liquid substances or mixture of liquids and solids from the ore processing process.
How many dams does Vale have?
Vale operates 133 iron ore dams in country, of which 105, or 80%, are located in
Gerais. In addition, the company has 21 iron ore dams in Pará and seven in Mato
What is decommissioning?
Decommissioning is the process of ending use of a dam permanently. After the works
carried out, the remaining structure is no longer characterized as a dam and is
reincorporated into the relief and the environment.

On January 27, 2019, Vale’s Board of Directors created two Extraordinary Independent
Consulting Committees: The Extraordinary Independent Consulting Committee for
and Recovery ("CIAEAR"), dedicated to following up the measures to assist the
and recover the area affected by the dam breach, ensuring allocation of all required
resources, and the Extraordinary Independent Consulting Committee for Investigation
("CIAEA"), to help investigate the facts that caused the breach and find the persons
responsible for it.
On February 15, the company announced the formation of a third committee,
Independent Consulting Committee for Dam Safety ("CIAESB"), which will be dedicated
advising the Board on issues related to the diagnosis of safety conditions,
and mitigation of risks related to Vale’s ore tailings dams, as well as recommending
measures to strengthen safety conditions.
