The auditing of air pollution fee collected from gasoline/diesel during Jan. to Oct. 2006 was completed and the results were quite satisfied. Respectively, the total quantities of gasoline and diesel are 8.64 millions and 4.3 million kiloliters. The shares of primary, secondary and third-grade gasoline are 50%, 46%, and 4%. The air pollution fees attributed to gasoline and diesel are NT$ 473 million and NT$ 430 million. 216 gasoline random samples and 205 diesel random samples, taken from fuel storages and gas stations, were analyzed. Thirty-one samples of illegal fuels were found in the scheme. Unqualified diesel oil is mostly fishing boat uses with the oil stream, and the unqualified gasoline mixture of benzene and toluene. This project has set up a chromatographic band for investigated and analyzed possible source of illegal fuels. In this year, the project covers the gasoline and diesel’s prices of different countries, regulation, automobile’s fuel, bio-resource regulation trend, and the information of automobile’s exhaust. Furthermore, the project finished investigation of the amount of fuel’s consumption, and estimated air pollution in Taipei and Kaohsiung. This project helped the EPA to revise the “Standard of Characteristic and Performance on Gasoline and Diesel for Automobile” and “Air Pollution Control Fee of Gasoline and Diesel”. The new air pollution control fees will become effective from the beginning of the next year, which will depend on sulfur content with three different levels.
