Evaporative Emissions Standards & Regulations John Adey, Technical Director ABYC

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

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

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

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

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

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

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

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

Pressurization? 33CFR ► ► (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 (b)(5).

@ 3 PSI

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

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.

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

How Many Different Nozzles?

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