1 Evaporative Emission Standards for Boats Mike Samulski Office of Transportation and Air Quality International Boat Builders’ Exhibition & Conference Session 309: Boat Fuel Systems October 7, 2008

2 Outline Overview of new program 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 HC+NOx 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 Refueling/spillage Venting emissions (diurnal, hot soak, running loss) 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

9 Marine Evap Standards Standard/ Category Hose Permeation Tank Permeation Diurnal Standard level15 g/m 2 /day1.5 g/m 2 /day0.40 g/gal/day Portable tanks2009 a b PWC Other tanks2009 a c,d a 2011 for primer bulbs. Phase-in for under cowl fuel lines, by length, on OB engines: 30% 2010, 60% 2011, 90% 2012, 100% 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, 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.

10 Program Details Hose Permeation Diurnal Refueling Spillage Tank Permeation Small Business Provisions Certification

11 Fuel Line Permeation Fuel line –15 g/m 2 /day, 2009 Fuel CE10, 23°C –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/m 2 /day hose Molded hose and other rubber components –Fluoroelastomer construction –Alternative primer bulb products rubber barrier layer reinforcement cover

13 Fuel Tank Permeation 1.5 g/m 2 /day –E10 fuel, 28°C –Preconditioning Fuel soak Durability testing Design-based certification –Metal tanks –Automotive type multi-layer tanks Tank manufacturer will certify

14 Technical Approaches Multi-layer constructions Alternative materials Barrier treatments Barrier platelets Coatings Nanocomposites

15 Diurnal Standards Portable fuel tanks –Self-sealing valve Installed tanks –Trailerable boats (<26 ft) 0.40 g/gal/day °C –Nontrailerable boats 0.16 g/gal/day °C Tank manufacturer will certify

16 Technical Approaches Design-based certification –Seal tank (up to 1.0 psi) Can use pressure mitigation (e.g. bladder) –Passive-purge carbon canister Prevent fuel from entering canister Carbon and canister specifications canister in boat

17 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 Refueling

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

19 Potential Canister Installation

20 Small Businesses Small Business Regulatory Enforcement Fairness Act –Convened SBREFA Panels in 2001 and 2006 –Representatives from engine, boat, tank, and hose manufacturers Rule includes all recommendations from panel report –Appropriate lead time –Broad definition of emission family –Compliance progress review for fuel tanks –Engineering design-based certification for tanks –Fuel tank credit program –Hardship provisions

21 Certification Procedures The ABCs of getting a Certificate of Conformity with EPA emission regulations…

22 Certification Procedures The basics: –If your product is subject to EPA emissions standards, you must obtain a Certificate of Conformity before you introduce it into US Commerce. Must demonstrate compliance with the applicable regulation. –Certificates are issued by the Compliance and Innovative Solutions Division (CISD), Office of Transportation and Air Quality. CISD’s Heavy-Duty and Nonroad Engines Group processes the Applications for Certification for Marine SI –You must certify every model year or production period

23 How do I certify? To obtain a Certificate of Conformity: 1.Read the regulations! SD/I & components: 40 CFR Parts 1045, 1060, 1065 and 1068 OB/PWC: add 40 CFR Part Request an EPA Manufacturer Code: Contact: Mr. Pete Petersen, ; 3.Determine: Engine Families/Permeation Families The type of Certificate you need: –Exhaust, Evaporative (fuel lines, fuel tanks), or both

24 How do I certify? 4.Gather your data 5.Pay your fee: Per Application Information: Pay electronically at: Contact: Mr. Bill Vanden Broek ov *The amount of the fee depends on the calendar year in which the application is submitted, not the engine’s model year.
