Portable Fuel Container Public Workshop

1. California Air Resources Board Portable Fuel Container Public Workshop Monitoring and Laboratory Division Understanding Spillage October 20, 2004

2. Agenda • Introduction • Review PFC Control Strategies • Emission Reduction Estimates • Causes of Spillage • Spillage Control Alternatives • Next Steps

3. Introduction • March 2004 Workshop • Introduced revised Regulation, new Certification Procedure and draft test methods for PFC’s • Reviewed consumer comments • Reviewed manufacturer’s consumer findings • ARB conducted in-house consumer testing • May 2004 Workshop • Introduced concept of Consumer Acceptance to improve usage and acceptability • Drafted new Spill-Proof Spout test method that used multiple test fixtures to simulate more equipment

4. Introduction (cont.) • August 2004 Focus Group • ARB contracted a Focus Group to observe consumer behavior with existing cans and spouts • Focus Group also investigated Consumer Acceptance criteria and examined feasibility • Group described some of the most common complaints and provided suggested improvements • Other (ongoing) • ARB continuing with residential and commercial telephone surveys • Surveys used to determine inventories, throughput and question consumer experiences

5. Review PFC Control Strategies • Three control strategies designed to reduce emissions from 99 to 24 TPD • Categories include: • Evaporation (83 TPD) • Permeation (8 TPD) • Spillage (8 TPD)

6. Emission Reduction Estimates • Two strategies effective at reducing emissions: • Evaporation, very effective • Permeation, mostly effective • Spillage strategy effectiveness unclear • Consumer Complaints • Focus Group Findings • In-House Testing • Telephone Survey Results

7. Emission Reduction Estimates (cont.) • Evaporation (Automatic Closure) • Requires a spout to remain closed when stored • Prevents vapor from evaporating into the atmosphere • A projected 61 TPD emission reduction • Currently estimated as a 61 TPD reduction. • Permeation (Barrier Treatments) • Designed to prevent plastic containers from saturating with fuel and emissions escaping into the air • A projected 6 TPD emissions reduction • Currently estimated at 3 TPD emissions reduction

8. Emission Reduction Estimates (cont.) • Spillage (Automatic Shut Off) • Requires spout to automatically stop • Designed to prevent overfilling equipment • A projected 8 TPD emission reduction • Reductions currently unclear

9. Causes of Spillage • Operator Error • Pre-Regulation • Sloppy fuel transfer • Over filling • Post-Regulation • Not understanding the instructions • Using the PFC incorrectly • Functional Failure • Pre-Regulation • Leaking components • Post-Regulation • Broken and sticking spouts • Automatic shut-off failure • Spouts don’t fit all applications

10. Spillage Control Alternatives • Enhance PFC’s usage controls • Other?

11. Spillage Control Alternatives (cont.) • Enhance PFC Usage Controls • Introduce anti-dripping language for spouts • Multiple spout test fixtures • Certification Procedure • Enhanced labeling requirements • Consumer Acceptance requirements

12. Spillage Control Alternatives(cont.) • Other?

13. Next Steps • Control strategy decision • ARB staff to rework the PFC Regulation • Next Workshop January-February 2005 • Regulation to the Board 2nd Quarter 2005
