Sources: 5. Developments: 2. Following resident complaints regarding fuel odors causing dizziness and vomiting, Thai energy officials discovered approximately 200,000 liters of unauthorized diesel fuel stored in six large tanks at a data center in the Rama 9 area of Bangkok. The facility lacked the required permits under the Fuel Oil Control Act B.E. 2542. Legal proceedings were initiated at Makkasan Police Station, and authorities ordered the removal of the fuel. Subsequent cleanup operations managed by the Pollution Control Department and the Huai Khwang District Office addressed oil contamination found in the facility’s wastewater holding tanks and public drainage pipes. Efforts to prevent runoff into the Samsen Nai Canal included using sandbags, oil-removing agents, and vacuuming wastewater. Environmental monitoring indicated a decrease in Volatile Organic Compounds (VOCs) in drainage pipes, with internal holding tanks eventually testing at 0 ppm for VOCs, hydrogen sulfide, and Lower Explosive Limit (LEL). ## Timeline ### 2026-09-06: Rama 9 Data Center oil contamination cleanup underway Authorities are cleaning up oil-contaminated wastewater and sludge at a Rama 9 data center to prevent pollution from entering the Samsen Nai Canal in Bangkok. 2 sources. https://clstr.news/cluster/rama-9-data-center-oil-contamination-cleanup-underway ### 2026-09-03: Thai energy officials sue Rama 9 data center over unauthorized diesel storage Thai energy officials are taking legal action against a Rama 9 data center for storing 200,000 liters of unauthorized diesel fuel following resident complaints of strong odors. 4 sources. https://clstr.news/cluster/thai-energy-officials-sue-rama-9-data-center-over-unauthorized-diesel-storage --- Cite as: Rama 9 data center fuel and contamination incident.
