  1. Evaporative EmissionStandards for Boats Evaporative Emission Standards for Boats Office of Transportation and Air Quality IBEX Meeting October 2011

  2. Marine Evap Standards a2011 for primer bulbs. Phase-in for OB under-cowl fuel lines, by length: 30% in 2010, 60% in 2011, 90% in 2012, 100% in 2015. b Design standard. c Fuel tanks installed in nontrailerable boats (> 26 ft. in length or >8.5 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.

  3. Marine Diurnal Transition • Vessels manufacturers may produce proscribed number of diurnal-exempt vessels • Small Volume Exemption • 1,200 vessels between July 31, 2011 and July 31, 2013 • Other Exemption • 50% of production volume between July 31, 2011 and July 31, 2012 • Notifications sent to EPA by July 31, 2011 • 220 boat builders participating • 204 using 1,200 vessel option • 16 using % of production option

  4. Inventory Control • Manufacturers may exhaust fuel tank and engine inventory, per 1060.605(f) • In Model Year 2012, vessel with 2011 model year engine may use high permeation fuel tank • In Model Year 2013, vessel must meet all evaporative regulations, regardless of engine model year installed in vessel • Diurnal system standards apply on July 31, 2011, with no inventory provisions

  5. Inventory Examples • Vessel Manufacturer purchases 2011 model year engines through Dec 31, 2011 • High permeation fuel tanks • Certified diurnal system required unless vessel manufacturer is participating in Marine Diurnal Transition Program • On Jan 1, 2012, Vessel Manufacturer has 2011 engines and fuel tanks in stock • Vessels with 2011 engines may use high permeation fuel tanks • Vessel Manufacturer allowed to exhaust fuel tanks in stock • On Aug 1, 2012, Vessel Manufacturer begins building 2013 model year vessels • Certified, low permeation fuel tanks required • Certified diurnal system required unless vessel manufacturer is participating in Marine Diurnal Transition Program

  6. Vessel Labels • 2012 Model Year Vessel Label • Statement, “MEETS EPA EVAP STANDARDS USING CERTIFIED COMPONENTS” • Corporate name and trademark • Label not required on 2012 model year vessels with 2011 model year engines • Diurnal-exempt label • Heading “EMISSION CONTROL INFORMATION” • Corporate name and trademark • Vessel’s date of manufacture in Month and Year format • For vessels with inboard engines, date of manufacture is when engine is installed • For vessels with outboard motors, date of manufacture is when fuel tank is installed • Statement, “THIS VESSEL IS EXEMPT FROM DIURNAL STANDARDS UNDER 40 CFR 1045.625” • Label can be separate or combined with above label • Either or both labels can be combined with Coast Guard label

  7. Refueling Auto Shut-off • Per EPA regulations, all new fuel nozzles purchased by marinas must have automatic shut-offs • EPA requires vessel manufacturers use good engineering judgment to ensure no fuel spillage or spitback occurs during refueling event • If fuel system meets ABYC H-24 provisions, then the vessel will also meet EPA requirements

  8. E10/E15 as Certification Fuel? • EPA is expecting to propose a new certification fuel for cars and light-trucks at the end of 2011 • Likely to propose a 15% ethanol/gasoline (E15) blend • EPA recently approved a waiver for E15 and expects use to grow significantly in coming years • EPA is considering proposing the new certification fuel for all nonroad categories that use gasoline • Apply to Marine SI, Small SI, Large SI, and Rec Vehicles • Apply to both exhaust and evaporative emissions

  9. E10/E15 as Certification Fuel? • For nonroad categories, EPA has explored three options • E15 • E10 initially, then move to E15 after market review indicates E15 is a “significant” fraction of fuel sold • E10 • EPA would allow multiple years for manufacturers to re-certify their products on the new fuel • Open to allowing carryover of existing CE10/E10 data from fuel tank and fuel line permeation testing • No decisions have been made yet • Proposal will be available on EPA website after signature • http://www.epa.gov/otaq/hwy.htm
