E-85 Pumps Not Ul Safe

With thousands of flex-fuel vehicles hitting the road, gas stations are adding E-85 to
their fuels. E-85 is 85 percent ethanol and 15 percent gasoline. But, as Lester
Graham reports, storing and pumping E-85 fuel is a major concern because, so far,
no equipment has been certified as safe to handle it:


The Department of Energy’s Handbook for Handling, Storing, and Dispensing E-85
warns, “certain materials commonly used with gasoline are totally incompatible with
alcohols.” Other government guidelines give detailed instructions about storing E-85
in underground storage tanks and the pumps people use to fill their vehicles. But,
with more and more filling stations adding E-85 pumps, not everyone is following the
instructions and warnings.


Brad Hoffman is with the nation’s largest underground storage tank service
company, Tanknology. The company inspects gas station distribution systems:


“I think they pretty much just took for granted that their tank could store whatever
fuel they put into it and they didn’t really check the compatibility of the tank and the
other piping and dispensing equipment. They didn’t really confirm that it was
compatible with the E-85 that was being delivered.”


And some of the fiberglass underground storage tanks are not compatible. Ethanol
can soften the polymers in certain tanks. That can make them weaker and might
cause them to leak. There’s also concern that leak detection equipment might also
be damaged by ethanol. So if a tank is leaking, it might go undetected. And it’s not
just the tanks. There are questions about compatibility with the pumps filling flex-fuel
vehicles.


The ethanol industry says there have been no major problems with tanks or pumps
so far. Matt Hartwig is with the Renewable Fuels Association:


“Most gas station operators will use tanks that are appropriate. They will clean the
tanks. They would do the proper maintenance and the proper preparation required
to install E-85 infrastructure. Because of the nature of ethanol, you do need a
dedicated tank and pump system to dispense the fuel. I don’t think consumers and
the American driver have anything to fear.”


But fuel tank and gas pump inspectors are not as sure. Brad Hoffman with
Tanknology says government guidelines give checklists of recommendations on how
to prepare tanks and pumping systems:


“Being realistic, I think there’s a chance that some marketers may, you know, for
whatever reason, may not thoroughly check each of those items. And there could be
some problems, either with the tanks or the dispensing systems.”


Problems that could cause leaks.


Underwriters Laboratories is the safety testing organization that certifies the safety of equipment storing and pumping fuels. John Drengenberg is with
UL. He says it was only last year that a manufacturer asked for requirements for equipment handling E-85. Drengenberg says old gasoline equipment might not
be safe to pump E-85:


“The alcohol is different in that it’s much more corrosive. We know for a fact that
alcohol will attack soft metals, in particular aluminum and copper, things of that type,
and even plastics. So, therefore, what worked for gasoline dispensers, may not work
for ethanol dispensers.”


Drengenberg says gaskets, seals, and o-rings in the pump, hose or handle could
deteriorate and mean leaking fuel at the pump:


“With this type of fuel, ethanol, we’re mostly worried about fire hazards. If there is a
leak – let’s say for some reason ethanol attacked a gasket or a seal on a dispenser,
you could have a fuel leak – the fuel leak could be very dangerous in that any spark
could set it off. You could have a fire or possibly an explosion. So, that is the
concern that we have, certainly. And that is why we’re developing requirements for
these ethanol dispensers.”


UL expects to issue requirements for equipment by the end of the year. In the
meantime, whether the tanks and pumps offering E-85 at your gas station are safe is
up to the judgment of the local fire chief, fire marshal, or other local official.

INSURANCE RATES DRIVING SPRAWL? (Short Version)

Some big city mayors and urban legislators say insurance rates are unfair to people who live in cities. The GLRC’s Lester Graham reports, state legislatures are reluctant to change insurance rate structures in fear of angering suburban voters:

Some big city mayors and urban legislators say insurance rates are unfair
to people who live in cities. The GLRC’s Lester Graham reports, state
legislatures are reluctant to change insurance rate structures in fear of
angering suburban voters:


Insurance rates are higher in cities than they are in suburbs. Often
they’re much higher. Peter Kuhnmuench is an insurance industry
spokesman with the Insurance Institute of Michigan. He says there are
more risks and more insurance claims in the cities that drive up the costs.


“We see a higher incidence of fire and burglary and theft in the urban
areas typically than you do in the suburban areas.”


And although suburban residents typically drive their cars farther to
work, drivers in the city have more collisions and theft claims.


Legislators in cities want the insurance costs tp be spread out across a wider
population, but suburban legislators don’t want their residents to have to
subsidize urban insurance rates. Those in the city say the irony is:
through tax dollars, their residents are forced to subsidize more lanes of traffic for
the suburbanites who commute to work in the city.

Traffic Jams Waste Billions of Gallons of Fuel

Drivers are spending more time and burning more fuel stuck in traffic. An annual study found the
upward trend of more traffic congestion continues. The Great Lakes Radio Consortium’s Lester
Graham reports:


The latest report looks at 2001. It found that about half of the time we spend in traffic jams is due
to delays caused by accidents, vehicle breakdowns, weather and construction. But researchers at
the Texas Transportation Institute at Texas A and M University found that people are driving
farther to work and they’re also making more trips. Instead of combining trips to the bank, the
grocery store and the cleaners, more and more drivers tend to make separate trips, putting more
cars on the road at a time. David Schrank is one of the researchers. He says it ends up being a
huge waste of fuel.


“In 2001, almost five-point-seven billion gallons of fuel — that’s with a ‘b’– were wasted in
traffic congestion in 75 urban areas in the United States.”


And the study estimates we all spent more time, three-and-a-half billion hours, stuck in traffic
during the year.

Drivers Worry About Fuel Consumption

A survey of automobile drivers found many people complaining about higher than expected fuel consumption. The Great Lakes Radio Consortium’s Lester Graham reports:

A survey of automobile drivers found many people complaining about higher than expected fuel
consumption. The Great Lakes Radio Consortium’s Lester Graham reports:


The JD Power and Associates 2003 Initial Quality Study found that one of the top complaints of
drivers was fuel consumption. Perhaps not surprisingly, it was the number one complaint about
the massive military-modeled Hummer H2. But it was also a complaint about the hybrid models
such as the Toyota Prius, one of the most fuel efficient cars on the road. A JD Power and
Associates spokesperson didn’t want to be recorded, but in a statement indicated that drivers were
probably more aware of fuel consumption because of higher gasoline prices this past year. He
suggested the complaints about the hybrid and other compact cars likely came because drivers
found the cars didn’t always get the kind of mileage suggested by the Environmental Protection
Agency window sticker. That’s been the case in past years, but this year more drivers noticed the
difference.
