With widespread use of onboard systems, Stage II no longer effective, say the EPA. The agency 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. This final rule is part of the Obama Administration's initiative to ensure that regulations protect public health and the environment without being unnecessarily burdensome to American businesses, it said. Onboard refueling vapor recovery (ORVR) for capturing gasoline vapor when gasoline-powered vehicles are refueled is in widespread use throughout the highway motor vehicle fleet.
