Brazil's Dam Collapse Underscores Need for Improved Safety Standards Investment Research Metals & Mining Brazil’s Dam Collapse Underscores Need for Improved Safety Standards Alistair Godrich, Director, Research Analyst Lada Emelianova , Senior Vice President, Research Analyst Jennifer Anderson and Nikita Singhal, Senior Vice Presidents, Co-Heads of Sustainable Investment and ESG The collapse of a Brazilian dam owned and operated by Vale earlier this year has increased scrutiny of safety standards across the mining sector. The collapse near Brumadinho killed at least 160 people and is the second deadly dam failure in Brazil in the past five years. Lazard, like other investors, considers self-reported safety statistics and external audits completed by company- selected specialists to determine whether a company’s mining is safe and responsible. We have also had a series of meetings with mining companies since this tragedy. We have concluded that the mining industry needs improved global audit standards, alongside particular acknowledgement of the danger presented by upstream tailings dams. We believe that establishing global standards in mining practices and putting safety performance at the centre of companies’ remuneration policies are critical to prevent humanitarian disasters, address environmental risks, and protect shareholder value, especially over the long term. As we discuss below, our proxy voting and guidance will support efforts to establish an appropriate focus on long-term safety, thereby also enhancing shareholder value creation. LR31492 2 A Systemic Safety Challenge Establishing Global Standards The dam collapse near the town of Brumadinho, Brazil on 25 The failings of the Samarco and Brumadinho dams highlight January 2019 was caused by the failure of an upstream tailings the specific risks posed by the practice of storing wet mining dam. The Brumadinho disaster marked the second industrial tailings, but the mining industry has faced a number of safety accident involving a tailings dam in Brazil in the last five years. challenges in recent years. In 2017, there were a total of 219 coal In 2015, a burst dam at the Samarco mine killed 17 people, and mine accidents in China, causing 375 deaths.4 In February 2019, Vale, and co-owner BHP, are still in negotiations relating to a Glencore announced that a truck belonging to a contractor was lawsuit of approximately $41.5 billion (155 billion BRL)1.

Currently, individual countries are responsible for setting their What Is a Tailings Dam? own safety standards. Brazil is now looking to decommission all More than 80 dams in Brazil are built like those at Samarco and upstream tailings dams, joining Chile and Peru. Vale announced Brumadinho. A tailings dam is an artificial reservoir designed to store wet that it intends to decommission all upstream dams over the by-products of the mining process, i.e., tailings. Tailings are stored as slurries—typically above ground—rather than released to the water table next three years at a cost of $1.3 billion (5 billion BRL), while as they contain metal residues and processing chemicals. ArcelorMittal stated that it aims to halt the construction of new An upstream dam is created by the tailings themselves as their edges mines using wet tailings from 2024. At the industry level, the harden to produce walls. The wall grows in increments, built on top of International Council on Mining & Metals (ICMM)—a body previously hardened tailings. Upstream dams seemingly carry a higher risk of failure, particularly in wet weather areas. The structural integrity tasked with improving sustainable development performance of the wall depends on low moisture content within the tailings that form the wall, placing added importance on the proper removal and in the mining and metals industry—announced plans to review recycling of water in the tailings themselves. As such, an upstream dam global best practices by the end of 2019, following growing calls is deemed to be most suitable for facilities in areas with low rainfall, low seismic activity, and relatively flat terrain.3 from a number of mining companies for the creation of a global independent regulator to monitor the safety of tailings dams. It is Downstream dams grow with the wall being reinforced on the down- stream section of the dam. This normally requires more material and is hoped that this review will lead to the creation of a classification therefore costlier than an upstream dam. A centreline dam is a mix of system and independent reviews of tailings dams. both of these methods as it builds the wall up using the tailings in the dam, like it does in upstream dams, but also involves reinforcement of the downstream side of the wall. The centreline therefore rises vertically.

While tighter safety standards would likely increase Tailings operating costs, all the major miners we engaged with expected this to be manageable at prevailing commodity prices, including that of iron ore, which has strengthened considerably following the significant loss of output since the Brumadinho disaster (see Sidebar: Impact on Iron Ore Prices). Downstream Wall Increase While higher iron ore prices could support some companies in Downstream funding additional regulatory costs, should they be sustained, we believe that companies with safe storage methods and well- Tailings invested assets are better positioned over the medium term.

While safety measures are included in the Lost Production Has Led to a Steep Rise in Iron Ore Prices short-term compensation frameworks for the CEOs of Anglo ($/Tonne) American, BHP, and Rio Tinto, safety targets within long-term 100 incentive plans are notably lacking (Exhibit 1). The weighting of safety in mining companies’ short-term incentive plans, and its contribution to overall remuneration, is, in our view, insufficient 90 given that the companies have such high risk exposure. Lazard’s Response to the Brumadinho 80 Disaster We have had a series of meetings and discussions with the 70 management of mining companies since Brumadinho, focusing on tailings dams specifically, as well as broader mining safety issues.

  • BHP “Extreme” Consequence Tailings Dams with Potential to Cause Fatality of 100 Employees
    BHP “Extreme” consequence tailings dams with potential to cause fatality of 100 employees: Briefing Paper by David Noonan, Independent Environment Campaigner - 22 May 2020 BHP has Questions to answer on Worker Safety, Transparency and Accountability at Olympic Dam BHP took over Olympic Dam copper-uranium mine in 2005, operating the mine for a decade before a GHD “TSF Dam Break Safety Report”1 to BHP in August 2016 concluded all existing Tailings Storage Facilities (TSFs) are “Extreme” consequence tailings dams with a failure potential to cause the death of 100 BHP employees: “BHP OD has assessed the consequence category of the TSFs according to ANCOLD (2012a,b). A dam break study, which considered 16 breach scenarios of TSFs 1 to 5, was completed by GHD (2016) and indicated a potential for tailings and water flow into the mine’s backfill quarry and underground portal. The following conclusions were drawn: • The population at risk (PAR) for a TSF embankment breach is greater than 100 to less than 1000 mine personnel primarily as a result of the potential flow of tailings into the adjacent backfill quarry and entrance to the underground mine. • The financial cost to BHP OD for a tailings dam failure was assessed by BHP OD to be greater than US$1B, a “catastrophic” loss according to ANCOLD guidelines (2012a,b). Based on these criteria, the TSFs at Olympic Dam have been given a consequence category of “Extreme” to guide future assessments and designs. Note that this is an increase compared to the assessment prior to the FY16 Annual Safety Inspection and Review (Golder Associates, 2016a) which classified TSF 1-4 and TSF 5 as “High A” and “High B”, respectively.

  • Be Aware of Potential Risk of Dam Failure in Your Community
    Be Aware of Potential Risk of Dam Failure in Your Community Approximately 15,000 dams in the United States are classified as high-hazard potential (HHP), meaning that their failure could result in loss of life. Dams can fail for a number of reasons, including overtopping caused by floods, acts of sabotage, or structural failure of materials used in dam construction. The worst dam failure in the United States occurred in 1889 in Johnstown, Pennsylvania. Over 2,200 died, with many more left homeless. Dams present risks but they also provide many benefits, including irrigation, flood control, and recreation. Dams have been identified as a key resource of our national infrastructure that is vulnerable to terrorist attack. States have the primary responsibility for protecting their populations from dam failure. Of the approximately 94,400 dams in the United States, State governments regulate about 70 percent. About 27,000 dams throughout our Nation could incur damage or fail, resulting in significant property damage, lifeline disruption (utilities), business disruption, displacement of families from their homes, and environmental damage. The most important steps you can take to protect yourself from dam failure are to know your risk. Contact government offices to learn if an Emergency Action Plan (EAP) is in place and to evacuate when directed by emergency response officials. An EAP is a formal document that identifies potential emergency conditions at a dam and specifies preplanned actions to be followed by the dam owner to reduce property damage and loss of life. The plan may save lives and property damage through timely evacuations of those who live, work, or enjoy recreation near a high-hazard potential dam.

  • Effects of the Glen Canyon Dam on Colorado River Temperature Dynamics
    Effects of the Glen Canyon Dam on Colorado River Temperature Dynamics GEL 230 – Ecogeomorphology University of California, Davis Derek Roberts March 2nd, 2016 Abstract: At the upstream end of the Grand Canyon, the Glen Canyon Dam has changed the Colorado River from a run-of-the-river flow to a deep, summer-stratified reservoir. This change in flow regime significantly alters the temperature regime of the Colorado River. Seasonal temperature variation, once ranging from near to almost , is now limited to 7 . The lack of warm summer temperatures has prevented spawning of endangered 0℃ 30℃ humpback chub in the Colorado River. Implementation of a temperature control device, to − 14℃ allow for warmer summer releases to mitigate negative temperature effects on endangered fish, was considered by the federal government. Ultimately, this proposal was put on indefinite hold by the Bureau of Reclamation and U.S. Fish and Wildlife Service due to concerns of cost and unintended ecological consequences. The low-variability of the current dam-induced Colorado River temperature regime will continue into the foreseeable future. Agencies are reviewing humpback chub conservation efforts outside of temperature control. Keywords: Colorado River, Grand Canyon, Glen Canyon Dam, thermal dynamics 1.0 Introduction Temperature in natural water bodies is a primary driver of both ecological and physical processes. Freshwater plant and animal metabolisms are heavily affected by temperature (Coulter 2014). Furthermore, the thermal structure of a water body has significant impacts on the physical processes that drive ecosystem function (Hodges et al 2000); fluid dynamics drive transport of nutrients, oxygen, and heat. Human action, often the introduction of dams or industrial cooling systems, can alter the natural thermal regimes of rivers and lakes leading to reverberating impacts throughout associated ecosystems.

  • Hydroelectric Power -- What Is It? It=S a Form of Energy … a Renewable Resource
    INTRODUCTION Hydroelectric Power -- what is it? It=s a form of energy … a renewable resource. Hydropower provides about 96 percent of the renewable energy in the United States. Other renewable resources include geothermal, wave power, tidal power, wind power, and solar power. Hydroelectric powerplants do not use up resources to create electricity nor do they pollute the air, land, or water, as other powerplants may. Hydroelectric power has played an important part in the development of this Nation's electric power industry. Both small and large hydroelectric power developments were instrumental in the early expansion of the electric power industry. Hydroelectric power comes from flowing water … winter and spring runoff from mountain streams and clear lakes. Water, when it is falling by the force of gravity, can be used to turn turbines and generators that produce electricity. Hydroelectric power is important to our Nation. Growing populations and modern technologies require vast amounts of electricity for creating, building, and expanding. In the 1920's, hydroelectric plants supplied as much as 40 percent of the electric energy produced. Although the amount of energy produced by this means has steadily increased, the amount produced by other types of powerplants has increased at a faster rate and hydroelectric power presently supplies about 10 percent of the electrical generating capacity of the United States. Hydropower is an essential contributor in the national power grid because of its ability to respond quickly to rapidly varying loads or system disturbances, which base load plants with steam systems powered by combustion or nuclear processes cannot accommodate. Reclamation=s 58 powerplants throughout the Western United States produce an average of 42 billion kWh (kilowatt-hours) per year, enough to meet the residential needs of more than 14 million people.
