Updates to Draft Proposal • Implementation Dates – Harmonize with U. S. EPA rule for ≤ 40 HP beginning in MY 2012 – Harmonize with U. S. EPA rule for >40 HP in MY 2012 and MY 2013 – Set more stringent standards for >40 HP beginning in MY 2014 • ORVR – ORVR has been removed from the proposal – However, ARB proposal will require Phase II compatible fill deck plates 3/3/2010 4

Draft Proposal – Key Elements Options for Certification For >40 HP Proposed Spark-Ignition Marine Engine regulation has two methods of certification: • Design-Based – Requires low permeation components and standards for venting and marine engine performance – – low permeation fuel hose low permeation fuel tank venting performance test meet fuel injection definition or perform fuel injection performance test • Performance-Based Alternative – One standard applied to the complete evaporative system – – Based on a 24 -Hour Diurnal Test (California Summer Profile) The standard will be based on E 10 • 90% California Phase 3 Reformulated Gasoline with 10% by volume ethanol (Phase 3 CERT) 3/3/2010 6

Draft Proposal – Key Elements Design Requirements – Fuel Hose • Fuel Hose Permeation Standard – 5. 0 grams/m 2/day • Test Procedure – 40 CFR 1060. 515 – High Accuracy Option – SAE J 1737 – Test temperature • 40°C – Test fuel • E 10 or CE 10 3/3/2010 7

Draft Proposal – Key Elements Design Requirements – Fuel Tank • Fuel Tank Permeation Standard – 0. 70 grams/m 2/day • Test Procedure – 40 CFR 1060. 520 – Test temperature • 28°C – Test fuel • E 10 or CE 10 3/3/2010 8

Draft Proposal – Key Elements Design Requirements – Diurnal • Diurnal Performance Standard – 0. 25 grams/gallons/day • Test Procedure – 40 CFR 1060. 525 – Test fuel • E 10 • Diurnal standard can be met with any technology – However, if a pressure relief valve is used, durability must be demonstrated 3/3/2010 9

Draft Proposal – Key Elements Design Requirements – Fuel Tank • ARB performed 40 CFR 1060. 520 on a 33 gallon tank with a 1. 5 L canister 3/3/2010 10

Draft Proposal – Key Elements Design Requirements – Fuel Injection • Meet Fuel Injection Definition – “Fuel Injection is defined as any mechanical or electrical fuel system in which pressurized fuel is sprayed or injected into the intake system of an internal combustion engine. ” or • Perform Fuel Injection Performance Test – Standard • 0. 2 grams/hour – Test Procedure • TP-1502 – 3 -hour Hot Soak @ 105 F • Test fuel – E 10 3/3/2010 11
