Description

The American Petroleum Institute (API) commissioned this study to "Develop Fugitive Emission Factors and Emission Profiles for Petroleum Marketing Terminals" by screening and/or bagging components at three marketing terminals. The United States Environmental Protection Agency (U.S. EPA) separately funded the same test contractor (Radian) to test an additional terminal. The results for all four marketing terminals are presented in this report.

New average emission factors, new default zero emission factors, and new emission correlation equations were developed for the majority of the component types found in petroleum marketing terminals. In almost all cases the new average emission factors, new default zero emission factors and new emission correlation equations predict substantially lower emissions than those factors and equations determined in previous studies of the chemical and petroleum refinery industries. These emission factors are lower because of lower leak distributions and lower correlations between mass emissions and screening values.

In addition to screening and bagging, a test was performed to determine the quantities of liquid gasoline that leaked out of loading arms after filling the gasoline tank trucks. These drips occur immediately after the trucks have been loaded and the liquid loading arms released from the trucks. In almost all cases the measured drip volumes per loading arm were below the detection limit of the measuring instrument (0.1 mL per truck loading event), indicating that these drips result in minimal emissions.
