a 2011 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.

Marine Diurnal Transition

3 • 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

Inventory Control

4 • 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

Inventory Examples

5 • 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

Vessel Labels

6 • 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

Refueling Auto Shut-off

7 • 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

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
