  1. ARB’s Intent to Establish Evaporative Emission Standards for Pleasure Craft NMMA/ARB Meeting Feb. 7, 2006

  2. Why is ARB Considering Evaporative Emission Standards for Pleasure Craft? • California needs significant additional emission reductions to attain ambient air quality standards. • There is a large population of pleasure craft within California (estimated at 850,000). • Evaporative emissions from pleasure craft are estimated to be 22 tons per day (annual average). • Cost effective solutions may be available.

  3. Potential Control Technologies to be Evaluated • Active and passively purged carbon canisters • Low permeation fuel hoses • Low permeation fuel tanks • Insulation

  4. ARB’s Baseline Evaporative Emissions Testing • ARB conducted baseline evaporative emissions testing on nine pleasure craft • Diurnal, hot soak, and some refueling data were generated • Running loss data is needed to complete the emissions inventory

  5. ARB’s Evaporative Emissions Testing (Continued) Note: Complete boats and PWC were tested in SHEDs.

  6. NMMA’s Evaporative Emissions Testing • ARB is willing to consider industry generated data to help determine potential standards • ARB is requesting that NMMA share its evaporative emissions data

  7. Next Steps for Rule Development(Tentative) • Initial Workshop • March 2006 • Emissions Inventory Development • Spring 2006 – Spring 2007 • Control Technology Evaluation • Summer 2006 – Summer 2007 • Development of Staff Proposal • Summer 2007 – Winter 2007 • Board Hearing • Early 2008
