To implement environmental protection policies on mobile source pollution control and to protect public health, on 6 December 2018 the EPA amended the Standards for the Compositions of Automobile Gasoline and Diesel Fuels. The amendments were formulated in reference to the control standards for petroleum-based fuels used by other Asian and European countries and the US, and will tighten controls over the composition of fuels.
Burning gasoline and diesel fuels emits nitrogen oxides (NOX), sulfur oxides (SOX), hydrocarbons (HC) and other various toxic substances that can lead to environmental effects such as unpleasant odors, acid rain and smog. Many countries around the world are thus gradually adjusting their environmental laws towards stricter controls on mobile sources of pollution and fuel compositions. To keep in line with international standards and contribute to air quality improvement, Taiwan is also making several revisions to the nation’s current control standards. Most equipment used for construction and agricultural purposes in Taiwan that runs on gasoline and diesel fuels already falls under the jurisdiction of the current standards and there is no need for revisions. However, the EPA is now including motor boats and aircraft as control targets under the Standards so as to further reduce air pollution and its impacts on human health.
The main focus of the amendments include: renaming the original regulation to Standards for Fuel Compositions of Mobile Sources; adjusting the maximum benzene content in gasoline to 0.8% and the maximum polycyclic aromatic hydrocarbons (PAH) content in diesel fuels to 8%; and, limiting the maximum sulfur content in marine fuels to 0.5% and in aviation fuels to 0.2%.
The Standards for Fuel Compositions of Mobile Sources took effect on 1 January 2019. Hence, the EPA recommends early adaptations to be made in response to the amendments.
