  1. Evaporative Emissions Standards & Regulations John Adey, Technical Director ABYC

  2. Philosophy & Misnomers • The ONLY Federal Regulations that apply to Recreational Boat Construction are found in Title 33 the Code of Federal Regulations. • This recent EPA Ruling has changed that • Title 40 part 91 Contains the Rule • ABYC WILL be adding this to the CD and Other Electronic products as permission is given

  3. Philosophy & Misnomers Cont… • This is FEDERALLY ENFORCEABLE • Non Compliance WILL cause a Recall • Talks on-going for inspection of the EPA Requirements during the USCG Factory Visit. • NMMA Certification will follow the EPA Implementation times, NOT ABYC’s

  4. Construction Standards? • What’s Out there? • SAE J1527 Fuel Hose • ABYC H-24 Gasoline Fuel Systems On Board Boats • ABYC A-XX Carbon Canisters • ABYC H-XX Non Metallic Fuel Tanks

  5. How Have These Changed?Fuel Hose • You are Already Seeing It • A-1-15 = EPA Compliance, USCG Compliance, ABYC Compliance

  6. ABYC H-24 July 2010 • Already has the option of A-1-15 Hose • Per SAE J1527 • Will Require A-1-15 Hose • Published July 2009 Effective July 2010 • So…BY July 2010 Compliance with ABYC = USCG, EPA, NMMA

  7. CANISTERS • NO Industry Standard Exists Today • Auto Industry = Proprietary • Incredible help from Industry • Standard Underway • Construction in A-XX • Installation in H-24

  8. Key Marine Points in A-XX • Able to Handle Condensate, Corrosive Environment • Not Block Flow – e.g. No Pressure • Keep Carbon Intact • Pass Fire Test – If Installed in Engine Cpt. • Volume of Carbon vs Tank size • <26’ .04 x Tank Capacity • ≥26’ .016 x Tank Capacity

  9. Key Points for H-24Under Consideration: • Self Draining • NO Fuel in the Canister **EVER** • Check Valve etc.etc. • Mounting • Fire Test? • Daisy-Chained?

  10. Pressurization? 33CFR 183.520 • (a) Each fuel tank must have a vent system that prevents pressure in the tank from exceeding 80 percent of the pressure marked on the tank label under Sec. 183.514(b)(5).

  11. @ 3 PSI

  12. Solution? Could Be. • Considerations for Safety Standards: • Securing the tanks • Connection Methods • Hose Types • Cap & Vent durability testing • Engine Connections

  13. Spitback? The Wording: • You must design and build your equipment such that operators can reasonably be expected to fill the fuel tank without spitback or spillage during the refueling event.

  14. Spitback? • Mentioned, though vaguely. • Could be a key point to the canister install • EPA is attempting to standardize nozzle size • Fill rates vary from standard auto 9-12 gpm • Fill habits vary from trailer to in-water • A not-to-ignore item, we were not expecting • H-24 will have to deal with this

  15. How Many Different Nozzles?

  16. Tank Permeation • Barrier coat? • New Plastics? • Blow Molding? • Rotational Molding? • Conventional Testing? • Possible ABYC H-XX Standard for Non-Metallic Fuel Tanks.
