Evaporative Emission Standards for Boats

Mike SamulskiOffice of Transportation and Air Quality

International Boat Builders’ Exhibition & Conference

Session 309: Boat Fuel SystemsOctober 7, 2008

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

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.

Fuel Line Permeation

• Fuel line– 15 g/m2/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/m2/day hose

• Molded hose and other rubber components– Fluoroelastomer construction– Alternative primer bulb products

Fuel Tank Permeation

• 1.5 g/m2/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• 25.6-32.2°C

– Nontrailerable boats• 0.16 g/gal/day• 27.6-30.2°C

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

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

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 91• http://epa.gov/otaq/marinesi.htm

2. Request an EPA Manufacturer Code:• http://epa.gov/otaq/verify/mfr-code.htm• Contact: Mr. Pete Petersen, 734.214.4204;

petersen.pete@epa.gov

3. Determine:• Engine Families/Permeation Families• The type of Certificate you need:

– Exhaust, Evaporative (fuel lines, fuel tanks), or both
