Recommendation on Feasibility for Onboard Refueling Loss Control

摘要

Refueling loss hydrocarbon emissions, estimated to be in the range of 4-5 g/gallon, can be controlled by use of control equipment at the service station (Stage II control) or by use of control equipment in the vehicle (onboard control). As required by the 1977 amendments to the Clean Air Act, the Emission Control Technology Division (ECTD) of EPA has reviewed and analyzed available data on the feasibility and desirability of onboard refueling loss control which will be discussed in this report. This information will be combined by the Office of Policy Analysis with available Stage II control information to provide the basis upon which the Administrator may choose the best of the two strategies.
