1. Presented at the Fifth Annual California Unified Program Conference February 6, 2003 Enhanced Vapor Recovery Cindy Castronovo Air Resources Board Cal-EPA

2. 2 Outline Vapor recovery program background What is EVR? What is ISD and how does it work? Is EVR applicable to all gasoline dispensing stations? When will stations need to comply? What equipment may need to be upgraded? How much will it cost?

3. 3 Vapor Recovery Provides Large Emission Reductions ROG Reductions LEVCBGVR (SCAB 2010 tons/day) 0 20 40 60 80 100 120

4. 4 Regulatory Roles California Air Resources Board –Vapor recovery rulemaking –Certifies Phase I and Phase II systems State Water Resources Control Board – USTs, Overfill Prevention, Secondary Containment –Develops regulations enforced by CUPAs Local Air Pollution Control Districts –Permit GDFs and enforce vapor recovery rules

5. 5 Vapor Recovery at Service Stations Phase IPhase II

6. 6 EVR Modules Module 1: Phase I vapor recovery Module 2: Phase II standards & specs Module 3: ORVR compatibility Module 4: Liquid retention and nozzle spitting Module 5: Spillage and dripless nozzles Module 6: In-station diagnostics (ISD) PHASE I SYSTEM PHASE II SYSTEM

7. 7 Onboard Refueling Vapor Recovery or “ORVR”

8. 8 ORVR - Phase II Incompatibility

9. 9 In-Station Diagnostics (ISD) Identify failures automatically Notifies station operator Reduces emissions by early detection and prompt repair Supplements district inspections Concept similar to OBD for vehicles Tie-in to existing UST leak monitors

19. 19 ISD System Pilot Program ISD Workgroup formed Successful hands-off operation of five ISD stations for two months Passed challenge mode tests –99% detection –no false failures ISD systems demonstrated feasible

20. 20 Partial EVR Exemption for Districts in Attainment with State and Federal Ozone Standards Exempt existing sites from all EVR modules except ORVR compatibility ORVR compatibility to minimize benzene exposure New and modified stations must comply Six northern CA districts qualify

21. 21

22. 22 ISD Exemption and Phase-In

23. 23 EVR Implementation Dates Compliance Date - Date all facilities must comply Operative Date – Date when new or modified station must install equipment Effective Date – Starts the 4 year clock

24. 24 Current EVR Timeline

25. 25 October Staff Proposal

26. 26 Proposed EVR Timeline

27. 27 Proposed EVR Timeline Dotted box: time between start of 4-year clock and date required for new installations Start of solid bar: date required for new or modified facilities End of solid bar: date required for existing facilities (installed before start of bar) January 2003

28. 28 When Must I Upgrade to EVR? New Installations / Upgrades –July 1, 2001 Phase I –April 1, 2003 ORVR, Unihose –October 1, 2003 Phase II, ISD Existing Installations –April 1, 2005 Phase I, ORVR –October 1, 2007 Phase II –October 1, 2007 ISD (high thruput) –April 1, 2008ISD (medium thruput)

29. 29 Phase I System Components Spill containers & covers –drain valves Rotatable product and vapor adaptors –dust caps and drop tube Overfill prevention device –ball floats or drop tube OPD –Pressure/vacuum vent valve Tank gauge port components Other (extractor fittings, tool kits, etc.)

30. 30 EVR Phase I Certified Systems Phil-Tite(VR-101-B) drain valve for product side ball floats for overfill prevention OPW(VR-102-A) product drain valve drop tube overfill prevention http://www.arb.ca.gov/vapor/eo.htm

31. 31 Phase II System Components Dispenser & associated vapor piping Control board Nozzles & splash guards Hoses, break-aways, swivels Flow control units Vapor pump (for assist) Vapor processor

32. 32 ORVR Compatible Phase II Systems Healy(G-70-186 and G-70-191) nozzle senses ORVR vehicle and turns off assist vapor pump SaberVac(G-70-196) air ingestion varies depending on pressure differential across vapor pump Balance*(G-70-52, etc) no forced air ingestion *approval letter in February 2003

33. 33 EVR Phase II Certified Systems Required for new installations beginning October 2003 No EVR Phase II systems yet certified No EVR Phase II systems under test Expect testing to begin in February Will delay operative date if necessary to allow more time to certify systems

34. 34 Gasoline Stations (GDF) Rank by Volume Fuel Dispensed

35. 35 EVR Equipment and Installation Costs Per Station (from Oct 2002 EVR Technology Review Report)
