ARBs 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.

Potential Control Technologies to be Evaluated

• Active and passively purged carbon canisters
• Low permeation fuel hoses
• Low permeation fuel tanks
• Insulation

4
ARBs 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
ARBs Evaporative Emissions Testing (Continued)
Note Complete boats and PWC were tested in
SHEDs.
6
NMMAs 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
