Small Engines to Pollute Less

In the next few years, lawnmowers, weed whackers and many boat engines
might cost a little more… but they’ll pollute less. Mark Brush
reports the Environmental Protection Agency has proposed a new rule
aimed at cutting air pollution from these small engines:


Today’s lawnmowers and boat engines put out a lot more air pollution than
your car. That’s because your car has a catalytic converter that burns
up a lot of harmful chemicals.


The EPA says that to meet its new rule, many small engine makers will
eventually add catalytic converters to their equipment. In the past,
small engine makers have complained that adding catalytic converters
will increase the risk of fire.


John Millett is a spokesman with the EPA. He says the EPA studied the
safety issue before drafting the proposed rule:


“We found no increase of risk of fire. In fact, several of the experts
that we consulted actually suggested that because of reducing the
amount of fumes that would escape from these engines we would actually
see improved safety.”


If the rule is approved, it’s estimated that consumers would pay around
$300 more for a new boat engine, and around $25 more for a new lawn
mower.

Regs to Force Cleaner Lawn Mower Engines

A leading maker of small engines says it can adjust to a clean-air decision regarding sales in California. Chuck Quirmbach reports:


The US EPA is letting California require highly polluting small engines to be sold with catalytic converters that cut smog emissions by roughly 40%.


Wisconsin-based engine maker Briggs and Stratton, and politicians who represent some communities with Briggs factories, had fought California’s regulation. They contended it would be hard to make one set of engines for California and another for the rest of the country.


But company vice-president Tom Savage says Briggs has been anticipating the regulation and can handle it through segregating the firm’s inventory.


“Most of our products are sold through the big boxes. There are systems set up so that we can get inventory to the right spot.”


Savage says they’d already been expecting the EPA to require tougher pollution controls on small engines nationwide over the next one to five years.

Drivers Filling Up With Cleaner Fuel

  • Low-sulfur fuel is now available to everyone, even if they haven't realized it yet. (Photo by Pam Roth)

A quiet revolution of cleaner air began this year for cars
and trucks. Motorists might not know it, but they’ve been burning
low-sulfur fuel as part of a requirement under the federal Clean Air
Act. The requirement was put in place during the Clinton Administration.

A quiet revolution of cleaner air began this year for cars and trucks. Motorists might
not know it, but they’ve been burning low-sulfur fuel as part of requirement under the
federal Clean Air Act. The requirement was put in place during the Clinton Administration.
The Great Lakes Radio Consortium’s Mike Simonson reports:


Low-sulfur fuel is sometimes referred to as “green gas.” The gas isn’t really colored green.
But if it was, people might have noticed that they’re pumping different gas. For two years,
refineries in the United States have been investing millions of dollars to produce the new gas.
Dave Podratz is the manager of the Murphy Oil refinery in Superior, Wisconsin. He says his
refinery spent 26 million dollars to begin making the gas since October.


“It’s not the kind of thing you would notice, the average consumer going to the pump probably
wouldn’t even notice it watching tail pipe emissions, but the sufur dioxide emissions are
definitely going down.”


Podratz says the new fuel cut the amount of sulfur by 90 percent. And other tail pipe
emissions are going down as well. That’s because low sulfur fuel improves the efficiency
of your car’s catalytic converter, Which, in turn, reduces the amount of pollutants like
nitrogen oxide and carbon monoxide.
