Portable Fuel Container Public WorkshopCalifornia Air Resources BoardMonitoring and Laboratory DivisionOctober 20, 2004Understanding Spillage
AgendaIntroductionReview PFC Control StrategiesEmission Reduction Estimates Causes of SpillageSpillage Control AlternativesNext Steps
IntroductionMarch 2004 WorkshopIntroduced revised Regulation, new Certification Procedure and draft test methods for PFCs Reviewed consumer commentsReviewed manufacturers consumer findingsARB conducted in-house consumer testing
May 2004 WorkshopIntroduced concept of Consumer Acceptance to improve usage and acceptabilityDrafted new Spill-Proof Spout test method that used multiple test fixtures to simulate more equipment
Introduction (cont.)August 2004 Focus GroupARB contracted a Focus Group to observe consumer behavior with existing cans and spouts Focus Group also investigated Consumer Acceptance criteria and examined feasibilityGroup described some of the most common complaints and provided suggested improvements
Other (ongoing)ARB continuing with residential and commercial telephone surveysSurveys used to determine inventories, throughput and question consumer experiences
Review PFC Control StrategiesThree control strategies designed to reduce emissions from 99 to 24 TPD
Categories include:Evaporation (83 TPD)Permeation (8 TPD)Spillage (8 TPD)
Emission Reduction EstimatesTwo strategies effective at reducing emissions:Evaporation, very effectivePermeation, mostly effective
Spillage strategy effectiveness unclearConsumer ComplaintsFocus Group FindingsIn-House TestingTelephone Survey Results
Emission Reduction Estimates (cont.)Evaporation (Automatic Closure)Requires a spout to remain closed when storedPrevents vapor from evaporating into the atmosphereA projected 61 TPD emission reductionCurrently estimated as a 61 TPD reduction.
Permeation (Barrier Treatments)Designed to prevent plastic containers from saturating with fuel and emissions escaping into the airA projected 6 TPD emissions reductionCurrently estimated at 3 TPD emissions reduction
Emission Reduction Estimates (cont.)Spillage (Automatic Shut Off)Requires spout to automatically stopDesigned to prevent overfilling equipmentA projected 8 TPD emission reductionReductions currently unclear
Causes of SpillageOperator ErrorPre-RegulationSloppy fuel transferOver fillingPost-RegulationNot understanding the instructionsUsing the PFC incorrectlyFunctional FailurePre-RegulationLeaking componentsPost-RegulationBroken and sticking spoutsAutomatic shut-off failureSpouts dont fit all applications
Spillage Control Alternatives
Enhance PFCs usage controls
Spillage Control Alternatives (cont.)Enhance PFC Usage ControlsIntroduce anti-dripping language for spoutsMultiple spout test fixturesCertification ProcedureEnhanced labeling requirementsConsumer Acceptance requirements
Spillage Control Alternatives (cont.)Other?

IntroductionsDepending upon number of new participants, go around the room.Read off agenda items.Point out that we have modified the posted agenda.Try to open up audience to promote an interactive presentation and discussion.Briefly read each item verbatim.Promote audience interaction, try to get people to open up early.Briefly read each item verbatim.Promote audience interaction, try to get people to open up early.Briefly read each item verbatim.Promote audience interaction, try to get people to open up early.Briefly read each item verbatim.Promote audience interaction, try to get people to open up early.Briefly read each item verbatim.Promote audience interaction, try to get people to open up early.Briefly read each item verbatim.Promote audience interaction, try to get people to open up early.
July TimeframeWould like manufacturers to submit marketplace studies, test results, etc. to make it very productive session.
