• Evaporative emission types
• New Standards
• Program details
• Small businesses
• Certification
• Questions

3
Final Rule

• On September 4, 2008, EPA Administrator Steve
  Johnson signed, into law, new exhaust and
  evaporative emission standards for spark-ignition
  marine engines and vessels.
• These standards apply only to new engines and
  vessels sold for use in the United States.
• The standards will help reduce harmful
  health effects of ozone and carbon
  monoxide from these products.

4
Final Standards Overview

• HCNOx exhaust emission standards for SI marine
  engines are similar in stringency to existing
  standards in California
• New CO exhaust emission standards for all SI
  marine engines
• New Not-to-Exceed provisions
• New evaporative emission standards

5
Evaporative Emission Types
Venting emissions (diurnal, hot soak, running
loss)
Refueling/spillage
Permeation (fuel tank, hoses, other)
6
Highway Evap Standards
Three decades of automotive evaporative emission
control (full vehicle test/standards)
Nonroad equipment are just now becoming subject
to evaporative emission control
7
Existing Nonroad Standards

• Component based standards
• Fuel and tank permeation
• Component test for diurnal control
• Design-based certification
• Existing standards
• Large SI equipment (2007)
• Recreational vehicles (2008)
• Portable gas cans (2009)

8
New Standards

• SI Marine
• Portable tanks
• Tank permeation
• Self-sealing vent
• Vessels
• Hose and tank permeation
• Diurnal emissions
• Refueling spillage
• Small SI as well
• Hose and tank permeation
• Running loss

nontrailerable boats (gt 26 ft. in length or gt8.5
ft. in width) may meet a standard of 0.16
g/gal/day over an alternative test cycle. d The
standard is effective July 31, 2011. For boats
with installed fuel tanks, this standard is
phased-in 50/100 over the first two years. As
an alternative, small manufacturers may
participate in a diurnal allowance program.

Fuel Line Permeation

• Fuel line
• 15 g/m2/day, 2009
• Fuel CE10, 23C
• Boat and engine hose
• Phase-in for under cowl fuel line
• Primer bulbs, 2011
• Vent and fill lines
• Standards do not apply unless hose will hold
  standing fuel
• Fuel line manufacturers will certify

12
Technical Approaches

• Straight-run hose
• Low permeation hose widely available
• Fluoroelastomer/fluoroplastic barriers
• SAE J1527 includes specification for 15 g/m2/day
  hose
• Molded hose and other rubber components
• Fluoroelastomer construction
• Alternative primer bulb products

• Nanocomposites

15
Diurnal Standards

• Portable fuel tanks
• Self-sealing valve

17
Refueling

• Fuel nozzle standards
• Marinas must use standard nozzles whenever they
  replace existing nozzles or install new ones
• Same to those already used for motor vehicle
  pumps
• Standardized dimensions
• Automatic shut-off
• System integration
• Fuel systems should be designed to allow flow to
  nozzle for automatic shut-off
• Will help with carbon canister installation
  designs and reduce spillage

18
System Integration

• Industry consensus standards
• SAE J1527 addresses hose permeation
• ABYC H24 potential vehicle for specifying best
  practices for fuel system designs
• NMMA certification
• Canister installation standards
• Industry is developing canister installation
  practices in context of EPA USCG standards
• ABYC is assessing fuel/air separators and fuel
  system designs for spillage control
