  1. ARB Enhanced Vapor Recovery Update July 27, 2005 EVR Seminar Santa Barbara Cindy Castronovo Air Resources Board Cal-EPA

  2. Outline • EVR Background and Applicability • “New” vs. “Existing” Facility (major mod) • EVR Timeline • EVR Phase I • Liquid Retention Nozzle Requirement • ORVR Compatibility • Unihose Dispensers • EVR Phase II • In-Station Diagnostics

  3. 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

  4. 120 100 80 60 40 20 0 Vapor Recovery Provides Large Emission Reductions ROG Reductions (SCAB 2010 tons/day) LEV CBG VR

  5. Vapor Recovery at Service Stations Phase I Phase II

  6. EVR Applicability • Phase I and Phase II systems at gasoline dispensing facilities with underground storage tanks (USTs) • New and existing facilities • EVR does not require VR systems if not already required by district rule • EVR for ASTs is under development (www.arb.ca.gov/vapor/ast/ast.htm)

  7. Partial EVR Exemption for Districts in Attainment with State Ozone Standards • Exempts existing sites from all EVR modules except ORVR compatibility • ORVR compatibility required to minimize benzene exposure • New facilities and facilities with major modifications must comply with EVR

  8. Recent Change in State Ozone Standards • More stringent state ozone standard approved by ARB at April 2005 meeting • Still going through rulemaking process • May change district attainment status in the next year • CP-201 section 2.4.4 allows 4 years to comply if district reclassified

  9. “New” vs. “Existing GDF” • EVR standards phased in over several years with multiple deadlines • New facilities need to meet all operative EVR standards • Existing facilities have up to four years after the effective date of the standard to comply • “Major Modifications” change status from “existing facility” to “new facility” and trigger operative EVR requirements

  10. Phase I Major Modification Modification of the Phase I system that involves the addition, replacement, or removal of an underground storage tank, or modification that causes the tank top to be unburied, is considered a major modification of the Phase I system.

  11. Phase II Major Modification Addition, replacement or removal of 50 percent or more of the buried vapor piping, or the replacement of dispensers, is considered a major modification of the Phase II system. The replacement of a dispenser is not a major modification when the replacement is occasioned by end user damage to a dispenser. Phase II system upgrades to make the systems ORVR compatible do not constitute a major modification. Phase II system upgrades to comply with the under-dispenser containment requirement (CCR, Title 23, section 2636(h)(1)) initiated before January 1, 2004 do not constitute a major modification. Modifications to dispensers may require use of unihose configurations as described in CP-201 section 4.11.

  12. EVR Modules PHASE I SYSTEM Module 1: Phase I vapor recovery PHASE II SYSTEM 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)

  13. 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 EVR Implementation Dates

  14. 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.)

  15. EVR Phase I Systems • VR-101-E Phil-Tite • VR-102-E OPW • VR-103-A EBW • VR-104-A CNI http://www.arb.ca.gov/vapor/eo.htm

  16. EVR Phase I Installation Training • Manufacturers training plan is part of ARB certification requirements • Districts may choose to require that installers be trained • Warranty may be conditioned upon use of trained installers

  18. 350 ml Liquid Retention Standard • As of April 1, 2005, only nozzles meeting the liquid retention standard of < 350 ml/1000 gallons dispensed are allowed. • Allowable nozzles are listed in recently signed G-70-199-AJ

  20. Onboard Refueling Vapor Recovery or “ORVR”

  21. ORVR - Phase II Incompatibility

  22. ORVR Compatible Phase II Systems Healy (G-70-191 and VR-201-A) nozzle senses ORVR vehicle and turns off assist vapor pump Balance (G-70-52, etc) no forced air ingestion Hirt (G-70-177-AA) thermal oxidizer processor Gilbarco/OPW Vaporsaver (G-70-204) membrane processor

  24. ORVR Compatibility Deadlines * based on 2003 calendar year

  25. Unihose Requirement There shall be only one hose and nozzle for dispensing gasoline on each side of a multi-product dispenser (MPD). This shall not apply to facilities installed prior to April 1, 2003 unless the facility replaces more than 50 percent of the dispensers. Facility modifications that meet the definition of “major modification” for a Phase II system in D-200 trigger the unihose requirement as the facility is considered a “new installation”. Exception: dispensers which must be replaced due to damage resulting from an accident or vandalism may be replaced with the previously installed type of dispenser.

  40. What ISD doesn't do Exempt station owners from receiving a notice of violation Identify single events that are out of the acceptable limits Identify borderline failures Exempt station owners from annual compliance testing

  41. ARB ISD Enforcement Policy • ISD output not currently appropriate for enforcement • No response by GDF operator to ISD failure signal is enforceable

  42. 18 Month ISD Evaluation • Examine the capital cost impacts of ISD on smaller throughput GDFs • Determine whether performance of field ISD systems is similar to performance of the system tested in certification

  43. In-Station Diagnostics (ISD) Exemption and Phase-In
