Technical guidance: State II vapor-recovery systems for control of vehicle-refueling emissions at gasoline-dispensing facilities. Volume 1. Chapters. Final report

Technical Report ·
OSTI ID:5706072

The Clean Air Act Amendments (CAAA) of 1990 require the installation of Stage 2 vapor recovery systems in many ozone nonattainment areas and direct EPA to issue guidance as appropriate on the effectiveness of Stage 2 systems. The document provides guidance on the effectiveness of Stage 2 systems and other Stage technical information on emissions, controls, costs, and program implementation. Stage 2 vapor recovery on vehicle refueling is an effective control technology to reduce gasoline vapor emissions that contain volatile organic compounds (VOC) and hazardous air pollutants. Vehicle refueling emissions consist of the gasoline vapors displaced from the automobile tank by dispensed liquid gasoline. The Stage 2 system collects these vapors at the vehicle fillpipe and returns them to the underground storage tank.
