Evaporative Emissions

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 ABYCs

4
Construction Standards?

• Whats 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
• SoBY 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
• lt26 .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
_at_ 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.
