3/3/20102 Presentation Outline Objective Updates to Draft Proposal Key Elements of Updated Draft Proposal –Options for Certification –Design Requirements –Performance Requirements –Compatibility Requirements Status of Emissions Inventory Rulemaking Timeline Comments/Questions?

3/3/20103 Objective Inform stakeholders of major changes to updated draft proposal

3/3/20104 Updates to Draft Proposal Implementation Dates –Harmonize with U.S. EPA rule for ≤40HP beginning in MY2012 –Harmonize with U.S. EPA rule for >40HP in MY2012 and MY2013 –Set more stringent standards for >40 HP beginning in MY2014 ORVR –ORVR has been removed from the proposal –However, ARB proposal will require Phase II compatible fill deck plates

3/3/20105 Draft Proposal – Key Elements Summary Table - ≤40HP Design Requirements Harmonized Design Based Standards (≤ 40 HP) Effective Date Model Year Applicable Marine Vessel Type and Test Procedures Under Cowl Fuel Hose Permeation Grams/m 2 / Day ROG Fuel Hose Permeation Grams/m 2 / Day ROG Fuel Tank Permeation Grams/m 2 / Day ROG Diurnal Requirement Grams/Gal/ Day HC Fuel Injection Or Equivalent Grams/Hr Fuel Cap Grams/m2/ day ROG 2012 and later All Marine Vessels N/A1.5 Test Procedure 40 CFR § CFR § or SAE J CFR § CFR § N/ A 40 CFR § ARB Certification begins in MY2012 Can only certify by design

3/3/20106 Draft Proposal – Key Elements Options for Certification For >40HP 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 E10 90% California Phase 3 Reformulated Gasoline with 10% by volume ethanol (Phase 3 CERT)

3/3/20107 Draft Proposal – Key Elements Design Requirements – Fuel Hose Fuel Hose Permeation Standard –5.0 grams/m 2 /day Test Procedure –40 CFR –High Accuracy Option – SAE J1737 –Test temperature 40°C –Test fuel E10 or CE10

3/3/20108 Draft Proposal – Key Elements Design Requirements – Fuel Tank Fuel Tank Permeation Standard –0.70 grams/m 2 /day Test Procedure –40 CFR –Test temperature 28°C –Test fuel E10 or CE10

3/3/20109 Draft Proposal – Key Elements Design Requirements – Diurnal Diurnal Performance Standard –0.25 grams/gallons/day Test Procedure –40 CFR –Test fuel E10 Diurnal standard can be met with any technology –However, if a pressure relief valve is used, durability must be demonstrated

3/3/ Draft Proposal – Key Elements Design Requirements – Fuel Tank ARB performed 40 CFR on a 33 gallon tank with a 1.5L canister

3/3/ 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 105F Test fuel –E10

3/3/ Draft Proposal – Key Elements Summary Table - >40HP Design Requirements Design Based Standards (> 40 HP) Effective Date Model Year Applicable Marine Vessel Type and Test Procedures Under Cowl Fuel Hose Permeation Grams/m 2 / Day ROG Fuel Hose Permeation Grams/m 2 / Day ROG Fuel Tank Permeation Grams/m 2 / Day ROG Diurnal Requirement Grams/Gal/ Day HC Fuel Injection Or Equivalent Grams/Hr Fuel Cap Grams/m2/ day ROG 2012 and 2013 All Marine Vessels N/A1.5 Test Procedure 40 CFR § CFR § or SAE J CFR § CFR § N/ A 40 CFR § and later All Marine Vessels With Horsepower > 40 HP Test Procedure *40 CFR § ***40 CFR § or SAE J1737 *40 CFR § **40 CFR § **TP-1502 *40 CFR § *Using a test fuel of either Phase 3 CERT fuel or CE 10 fuel. **Using Phase 3 CERT fuel. ***Using Phase 3 CERT fuel or CE 10 fuel with a test temperature of 40° C. As an option for high accuracy testing, manufacturers may use SAE J1737. ****ARB certification begins in MY 2012.

3/3/ Draft Proposal – Key Elements Performance Requirements Performance Alternative Standard Test Procedure TP-1501 –One 24-hour diurnal SHED test using the California Summer Profile Test fuel –E10 Performance Requirements Effective Date Model Year Applicable Vessel Type Diurnal Standard Grams HC/day 2014 and subsequent All Spark-Ignited Marine Vessels with Engine Horsepower > 40 HP * Tank Volume (liters)

3/3/ Draft Proposal – Key Elements Compatibility Requirements Fuel fill deck plate design –Meet fill pipe face requirements in fill plate design 13 CCR Section 2235 Fuels –The fuel system must be compatible with commercially available pump fuel for sale at the time the boat is sold

3/3/ Status of the Emissions Inventory Updated emissions inventory will include: –Additional SHED testing data –CSUS storage and usage survey data –Updated growth population estimate based on economic impact of sales Estimated completion date: late March

3/3/ Rulemaking Timeline Final Workshop –A workshop for the Spark-Ignition Marine rulemaking will be held on April 28 Board Hearing –Staff is preparing to go to the Board in September
