    Effect of Proposed Evaporative
    Emission Standards for Marine
    The U.S. Environmental Protection Agency (EPA) is proposing new
    evaporative emission standards for gasoline-fueled boats and personal
    watercraft. These proposed standards would require most new boats
    produced in 2008 or later to be equipped with low-emission fuel tanks
    or other evaporative emission controls. This fact sheet describes the
    proposed program and its expected impact on boat manufacturers and
    fuel tank manufacturers.
    Why is EPA regulating marine fuel systems?
    We analyzed evaporative emissions from gasoline fuel tanks used in
    boats and determined that they emit over 100,000 tons of gasoline
    vapors each year across the United States. Most of these emissions occur
    either from permeation of the fuel through plastic fuel tanks and rubber
    hoses, or as a result of heating of the fuel from normal daily temperature
    changes (diurnal emissions). These vapors contribute to the formation of
    smog and contain toxic compounds such as benzene. The Clean Air Act
    requires EPA to set emission standards to address these problems. These
    impacts are described in more detail in “FAQ: Environmental Impacts of
    Recreational Vehicles and Other Nonroad Engines” (EPA420-F-01-030,
    September 2001).

    Who is responsible for compliance?
    The proposed regulations would apply to new boats when they are sold. So it would be
    the responsibility of the boat manufacturer to ensure that each boat sold is in compliance
    with the new standards. Boat manufacturers could choose to certify fuel tanks and hoses
    themselves or to purchase certified fuel tanks and hoses. Fuel tank and hose manufactur-
    ers who only sell products to boat manufacturers that certify their boats themselves would
    not be required to certify their tanks or hoses separately, but could chose to do so.
    What are the proposed standards?
    We are proposing standards for diurnal, fuel tank permeation, and hose permeation
    emissions. The proposed evaporative emission standards are 1.1 g/gallon/day for diurnal,
    0.08 g/gallon/day for fuel tank permeation, and 5 g/m
    /day for hose permeation. This
    represents about an 80 percent reduction from the average evaporative emission rate of
    current marine vessels.
    How would I comply with the standard?
    There are two ways in which you could show compliance with the diurnal standard. First,
    you could build all of your boats to have emission rates at or below of 1.1 grams per
    gallon. Second, you could choose to comply with this standard on average using various
    technologies. In either case, you would need to certify your emissions to EPA. For the
    permeation standards, all of your fuel tanks and hoses would have to have emission rates
    lower than the proposed standards.
    How do I certify?
    The Clean Air Act specifies that certification must be based on emission test data. Our
    program calls for a manufacturer to measure emissions from its fuel system according to
    new test procedures that we are proposing. These test procedures include separate meth-
    ods for measuring diurnal emissions, tank permeation, and hose permeation. However, we
    realize that few of the potentially affected manufacturers would have the ability to build
    their own test facilities and conduct their own emission testing. That is why we are
    proposing to allow manufacturers to use test data collected by EPA and others for se-
    lected marine evaporative emission control technologies. To use this data, you would only
    need to demonstrate that emission controls are sufficiently similar to the ones that we
    have already tested.

    Page 3
    Which technologies has EPA tested?
    We have tested several evaporative emission control technologies that we believe will be
    used by manufacturers to meet our marine evaporative emission standard. These include
    pressurized fuel tanks, insulated fuel tanks, and fuel bladders. We plan to continue
    testing and retesting these technologies during 2002 so that we have a reliable database
    when the Final Rule is published. We will also continue testing permeation barriers for
    fuel tanks and hoses prior to the Final Rule and any new technologies that are identified.
    What technologies could be used to meet the new standards?
    Each of the technologies being tested has some defining characteristics, as described
    below. If you can show that your controls have the same characteristics, then you can use
    the data we already have to show that you meet emission standards.
    • Nonpermeable tanks and hoses - We presume that metal tanks and hoses are
    nonpermeable, and that plastic tanks are permeable. However, we are aware that
    there are plastic tanks and rubber hoses that have very low permeability, especially
    those with some sort of a permeation barrier. Thus, you could certify a plastic tank
    or rubber hose as nonpermeable, if you can provide an appropriate data and techni-
    cal analysis.
    • Pressurized tanks with pressure-relief valves - The defining characteristics for
    pressurized tanks are the pressure at which the relief valve opens, and how it works.
    The system we tested works by remaining sealed until the tank pressure reaches the
    vent pressure, and then maintains a constant tank pressure by slowly bleeding
    • Insulated tanks - This approach works by minimizing the daily temperature change.
    The defining characteristic is the number of degrees that the fuel temperature
    changes when the insulated tank is exposed to the test temperature cycle in an
    enclosed environment compared to an uninsulated tank. Thus, you could use emis-
    sion test data if you could show that your insulation works to keep the temperature
    change from exceeding the temperature change observed in our test.
    • Bladder tanks - We tested a sealed bladder tank. All bladder tanks that are sealed
    should not have measurable diurnal emissions. However, a bladder tank that is
    vented can have significant emissions. Therefore, based on our current test data,
    only sealed bladder tanks would be needed.
    • Volume-compensating air bladders - The most critical characteristic for this system
    is the ratio of the volume of the air bladder to the vapor volume of the fuel tank.
    However, since these systems require small pressures or vacuum within the tank to
    open and close the bladder, the pressure relief system is also important.

    What else would I need to do to certify?
    In addition to providing test data, the proposed regulations would require that you submit
    an application for certification annually, and that you maintain records of your products
    for eight years.
    How does this affect small businesses?
    Many fuel tank manufacturers are small businesses. We incorporated provisions for small
    businesses into the proposal. It includes ample lead time, a number of technology options
    for compliance with the proposed requirements, and a set of flexibilities to ease certifica-
    tion and compliance after the rule is implemented.
    Are there potential safety implications?
    EPA consulted with the U.S. Coast Guard (USCG) throughout the development of this
    proposal. A key aim of our approach has been to develop technology options for both
    permeation and diurnal control which will meet USCG regulatory requirements and be
    safe in use. We will continue to consult with USCG on safety issues related to potential
    control technology and requirements throughout the rulemaking.
    How can I comment on the proposed rule?
    We welcome your comments on the proposed rule. You may submit comments by send-
    ing an E-mail to, or, for more detailed instructions on submitting
    written comments, please see the Federal Register notice. It is available from the EPA
    Air Docket by calling (202) 566-1742; please refer to Docket No. A-2000-02. In addi-

    Hey EPA how about you stop wasting time tinkering with private boat owners gas tanks and fix/fine the corporate industrial polluters who are actually actively destroying the environment.

    The EPA is out of touch with reality. Take trying to hold a no drip, no leak, child proof 5 gallon spout open without spilling anything because you can't hold the can correctly. You end up spilling more than it is worth and they all leak. I just bought the "old fashion' replacement nozzles for my cans.

    My Ford has a Diesel Particulate Filter. Good until it gets filled. Then it has to regenerate. You have to drive about 50 miles at 50 mph to do that. In the mean time your mph drops from 21 to 13 mpg until you go on the trip to clean out the filter. How does the EPA figure that is helping the environment by burning more fuel.

    So how many gallons of fuel did the existing tanks loose to be compliant with the new regs and at what cost to the consumer, volume and $$$$$$ that we now have to pay for the new boat, with the tank that costs more to build, rigg, and install.

    I just watched a show on FOX that interviewed the CEO of Blitz the"red plastic fuel cans" they have shut thier doors after 30 some years. Blitz can't fight all the lawsuit's by foolish/ Blitz cas can users that hurt themselves or others with their cans.
    The feds even wanted them to make a spark arrester plastic/metal nozzle to keep the flames from following the gas back into the can?

    Whatever....and the beat goes on...meaning that I can't think of anything intelligent to say about this except that some of you guys have some great points about this and should make those known to someone that can possibly do something about it.

    On the drippy, hard to use gas cans...DaveintheBush and others...Honda makes a red plastic gas can that says "no drip gas can" on it, and like everything else Honda does, it works, all the time and perfectly. It has a push button on top that is easy to use your thumb on when you hold and tip the can, and an extra handle on the 5 gallon one. So you can get the nozzle where you want it before anything comes out, and it shuts off with no drips. Also comes in 1 gal and 2 1/2 gal. should be able to get one at Haltness in Valdez. Now...only issue with these is when the can gets warm enough to build up some vapor pressure inside, and this is an issue with any gas can. You should push the button before picking the can up to release the vapor pressure...OMG, here comes another regulation!

    This is a huge issue with these non-vented cans. Ive had mine get a little warm (outside temp went from 40-65) at camp site and they look like they are gonna explode their so swollen. Then you vent em and guess what? All the friggin vapor comes out just like it would have if it had been venting all day not swelling to explosion size.

    Government regulations on stuff like this is so unnecessary and foolish its absurd. Another waste of tax payer money.

    I can't help but think boating safety will be compromised by this rule. You put anything in the fuel system to hold pressure with a relief valve is asking for trouble. Things need to be simple and reliable on boats. The Gub'mt doesn't think that way of course so we need to push back.

    Cap' N Ron is correct, Honda makes the best can on the market. I sell them at Alaska Pacific Rental in Palmer and will give you your money back if you don't like them. I also have a Sportsmans show special on Honda EU2000 generators for $950.00

    I am not an expert on this, but have been forced to learn. What it comes down to is all boat builders are required by law to meet the new EPA rules with boats built after August 1, 2013. The rules are based on car standards, which means you need expansion room to avoid spills due to expansion, at a level posture or at an up-to 18 degree angle.
    The side effects of these new regulations may mean smaller capacities in some cases to allow expansion room and/or redesign of the tank or boat shapes to maintain capacity and additional cost for approved hardware and larger tanks shapes to maintain capacity. Glen
