Thailand regulates VOCs emission from oil depot

Ministry of Natural Resources and Environment announced “Notification of the Ministry of Natural Resources and Environment on the Emission Standard of Vapor From a Bulk Gasoline Terminal B.E.2564 (2021)” in the Royal Gazette on 15 October 2021 by virtue of Enhancement and Conservation of National Environmental Quality Act, B.E. 2535 (1992). The notification, which repeals the previous notification established in 2010, sets out a standard limit for the emission of total volatile organic compounds (total VOCs) from the oil depot.

The vapor emission of total VOCs during the supply of gasoline from a tank truck shall not exceed 17 mg/L (Milligram Total VOCs / Liter in emitted vapor) per hour. The samples shall be collected from a stack of the vapor pollution control system by continuous sampling method or more than 4 times of sampling per hour for calculation of average value. In case the vapor pollution control system is not installed, a sample shall be collected at the point where possible maximum VOCs concentration exists. To prevent a disaster risk, the tools for sampling and measurement shall be explosion-proof.

The notification became effective on the following day of the announcement in the Royal Gazette.
