What is stage 2 vapor recovery?
What is stage 2 vapor recovery?
Gasoline dispensing pump vapor control devices, commonly referred to as Stage II Vapor Recovery Control, are systems that control volatile organic compound (VOC) vapor releases during the refueling of motor vehicles. The Stage II system controls the release of VOC, benzene and toxics emitted from gasoline.
What pollutants do vapor recovery nozzles remove?
Ozone also degrades rubber and plastic products. How effective is Vapor Recovery? Vapor recovery will remove about 95% of the vapors that escape when gasoline tanks are being refueled.
What is Stage 1 vapor recovery?
“What is Stage I Vapor Recovery?” Stage I Vapor Recovery is used during the refueling of gasoline storage tanks to reduce hydrocarbon emissions. Vapors in the tank, which are displaced by the incoming gasoline, are routed through a hose into the cargo tanker, instead of being vented to the atmosphere.
What is enhanced vapor recovery?
Page 1. Enhanced Vapor Recovery (EVR) prevents. the escape of smog-forming gasoline. vapors. Vapor recovery systems collect gasoline vapors during bulk fuel delivery (Phase I) or vehicle fueling (Phase II).
When did stage II refueling vapor recovery start?
——-f 1. Introduction Stage IIVRS were adopted by some states beginning in the 1980s to meet the ozone National Ambient Air Quality Standards (NAAQS). Stage II and ORVR are two types of emission control systems that capture fuel vapors from vehicle gas tanks during refueling.
What are stages of gas vapor recovery in Texas?
The United States Environmental Protection Agency (EPA) approved revisions to 30 Texas Administrative Code (TAC) Chapter 115, Subchapter C, Division 4 and Texas’ State Implementation Plan (SIP) for decommissioning Stage II vapor recovery equipment at gasoline dispensing facilities (GDF).
When was vapor recovery removed from the SIP?
It was required under the Federal Clean Air Act until the EPA issued a decision that on-board vapor recovery was in widespread use throughout the vehicle fleet, allowing states to request that requirements for Stage II be removed from their SIPs.
What are Stage II and ORVR emission control systems?
Stage II and ORVR are two types of emission control systems that capture fuel vapors from vehicle gas tanks during refueling. Stage II and vehicle ORVR were initially both required by the 1990 Amendments to the CAA under sections 182(b)(3) and 202(a)(6), respectively.
