Ozone: Stage Two Vapor Recovery Rule and Guidance
Guidance on Removing Stage Two Gasoline Vapor Control Programs from State Implementation Plans and Assessing Comparable Measures
This guidance document provides both technical and policy recommendations to states and local areas on how to develop and submit an approvable State Implementation Plans (SIP) revision seeking to remove or phase-out an existing State Two program. This guidance introduces methods and equations that could be used to calculate the emissions consequences of discontinuing State Two control programs for purposes of demonstrating compliance with specific Clean Air Act (CAA) provisions in sections 110(l) and 193 governing EPA approval of SIP revisions.

Final Rule Waives Requirements for Gas Pump Vapor Recovery
May 16, 2012 - EPA has determined that the systems used at gas station pumps to capture harmful gasoline vapors while refueling cars can be phased out. Modern vehicles are equipped to capture those emissions. Beginning later this year, states may begin the process of phasing out vapor recovery systems at the pump.
