Tailing Storage Failures and Environmental Risks
📌 Two companies, PT HNC and PT QMB, operating in the nickel industrial park (IMIP) faced severe tailing storage facility failures in March 2024, leading to fatalities and environmental contamination.
💧 The tailings, described as filter tailings (with 35% water content, often marketed as "dry"), turned to sludge when exposed to heavy rain, causing liquefaction and landslides.
⚠️ Reports detail a high accident rate, including three fatalities from a PT QMB collapse on March 21st, and previous issues like brake failure accidents at PT HNC.
🏭 Nickel production yields only about 0.7% nickel from the ore, resulting in vast amounts of tailing waste, annually equaling twice the total waste volume of Jakarta.

Safety Lapses and Regulatory Concerns
🚫 An immediate cause of the March incident was the continuation of operations during heavy rain, indicating a failure to halt activities despite known risks associated with unstable OR residue.
🚧 Workers reported unsafe equipment being forced into use and a complete lack of safety lighting in storage areas, with heavy machinery operating over the tailing dumps.
📜 Despite the breaches, PT IMIP reportedly received a Proper Blue award from the Indonesian government shortly after the tailing breaches, suggesting a lack of serious post-incident evaluation by regulatory bodies.
🚫 There is a critical lack of Green Open Space (Buffer Zone) between the industrial facilities and residential areas, with operations running directly adjacent to or even encroaching upon community land boundaries.

Health and Community Impact
🚱 Local residents report that surrounding water sources are no longer potable due to contamination from the tailing waste leaching into rivers like the Bahodopi River.
🤕 Exposure risks to the contaminated water include cancer risk and skin irritation/itching, as the acidic process liquid used in production remains in the tailing sludge.
🏗️ Communities are concerned as investment and construction have encroached upon areas surrounding the storage facilities, despite the recognized danger posed by storing toxic waste near settlements.

Geographical and Technological Vulnerabilities
🌋 The Morowali area is situated in a seismically active zone (part of the Seram-Matano fault line), making the region susceptible to earthquakes and further compounding the instability of the tailing dams.
🌊 The initial plan to dispose of the $6$ million tons/year of tailings into the ocean was blocked by NGOs; subsequent land-based dry stacking is proving environmentally hazardous due to volume and instability.
🔬 A recommended sustainable alternative is implementing biolixiviation technology to process lower-grade ores, which, while slower, reduces the volume of hazardous tailings produced compared to current chemical processes.

Key Points & Insights
➡️ Halt high-risk operations immediately when environmental conditions (like heavy rain) indicate a high probability of failure, overriding production targets, especially near unstable tailings.
➡️ Mandate and enforce a sufficient buffer zone (Green Open Space) between industrial waste storage and residential areas to mitigate cancer and dermal risks from contamination.
➡️ Authorities must establish an independent assessment body to evaluate tailing storage facilities, critically reviewing compliance records post-incident, rather than granting awards immediately after failures.
➡️ Explore and scale sustainable technologies like biolixiviation to drastically reduce the $6$ million tons/year of hazardous tailing waste generated annually.
