Authorities Probe Oil Leak on Bangkok Pipeline

The Pollution Control Department is investigating an oil leak in the drainage system along Fuel Road and Rama III Road in Bangkok, conducting detailed sampling and oil fingerprinting analysis to identify those responsible and urgently seal the underground pipe to prevent oil from escaping into public water sources.

On September 17, Dr. Surin Vorakitja, Director of the Pollution Control Department, reported on progress in the contamination investigation. Officials discovered a suspicious point in a 2.5-meter-deep pit where a pipe showed swelling and oil seeping out in droplets. Initial investigation revealed the pipe is part of Buffs Pipeline Transport Limited's oil transport system serving Makkasan, Don Muang, and Bang Pa-in, with Bangkok Fuel Pipeline and Logistics Limited holding the service contract. Experts have already pumped out the oil and are working to identify the exact leak point.

Dr. Surin explained that officials are attempting to slide back the pipe's protective sleeve to pinpoint the leak location precisely. If that fails, the pipe may need to be cut, requiring extreme caution due to fire risk. Initial measurements showed volatile organic compounds (VOCs) at 21 ppm at the site, with no explosion or fire hazard detected.

Oil samples have been collected for advanced chemical analysis using oil fingerprinting techniques to compare with samples from nearby oil transport operators, helping to identify the source accurately under legal standards. The pit area remains high-risk, requiring special safety precautions.

The Pollution Control Department will coordinate closely with Bangkok's City Administration and the Energy Ministry to monitor repairs and sealing of the underground pipe, ensuring no oil residue reaches public water sources. Residents in the surrounding area who detect strong odors or abnormalities in drainage systems can report emergencies to the Pollution Control Department's 24-hour hotline at 1650.
