Presentation Transcript

  1. Enhanced Vapor Recovery Workshop November 9, 1999 • New and/or Revised Test Procedures Volumetric Phase I (TP-201.1) Fugitive Emissions (TP-201.2F) Liquid Retention (TP-201.3E) P/V Valve Integrity (TP-201.2B, Appx. 1)

  2. Current Procedure Volumetric Efficiency  95% No Emission Factor New Procedure Volumetric Efficiency  98% Emission Factor - HC  0.17 lbs./1000 gallons Volumetric Phase I (TP-201.1)

  3. No Current Procedure In Place New Procedure Modified 2” Decay Test Measure HC Concentration In UST Ullage Record UST Pressure For Given Amount of Time Calculate Mass Emission Factor Based On HC Concentration and Avg. UST Pressure Fugitive Emissions(TP-201.2F)

  4. Quantifies Liquid retained in the: Nozzle Spout Vapor path (of nozzle and/or hose) Aspirator port and associated chambers Also quantifies Spitting Defined as liquid expelled from a nozzle when the lever of a nozzle of an inactive dispenser is squeezed. Liquid Retention (TP-201.3E)

  5. Current Methodology 300 Gallon Tank Simulates a UST Size Needed to Dampen Out Pump Pulsation Immobile, Requires Components To Be Brought In For Testing New Procedure Mobile - Can Be Used in Parts Houses and In the Field Measures Both Vacuum and Pressure Stds. PV Valve Integrity(TP-201.2B)

  6. Nozzle Vapor Check (TP-201.2B, Appx. 2) Valve Integrity 2” Pressure Decay (TP-201.3) (Include Drop Tube Flow Test) Phase II Certification (TP-201.2) Includes Vent Sleeve Change From Efficiency Based To Mass Based Spillage (TP-201.2C) “Dripless” Nozzles (TP-201.2D) Test Procedures Under Construction
