The Tennessee Department of Transportation now fuels at least 250 state vehicles with a biodiesel
blend in the Johnson City, Knoxville, Nashville, Chattanooga and Cookeville areas. TDOT is using B20
(20 percent biodiesel) in heavy-duty dump trucks and large pieces of equipment, such as bull dozers and
back hoes, loaders, pavers, bobcats, track hoes and water trucks. “It's imperative that government and
businesses begin identifying ways to improve air quality,” said TDOT Commissioner Gerald Nicely.
“Using biodiesel is an effective way TDOT can reduce harmful emissions and protect our environment.”
The Cherokee Boys Club, in Cherokee, North Carolina (of the Eastern band of Cherokee Indians) is
responsible for the school system, social services and enterprise departments. They began running their
construction equipment on B20 last fall. All 28 of their school buses are fueled with a biodiesel blend.
“The Cherokee people are very environmentally conscious,” said Frank Cooper, Cherokee Boys Club
Finance Manager. “Living at the foot of Great Smokey Mountain National Park, we have seen first-hand
the effects of pollution on trees and water, as well on asthma rates. Using biodiesel seemed like a logical
step we could take to protect the environment, and to decrease dependence on foreign oil.”
Manatt’s, Inc., a diversified construction company with operations in ready-mix concrete, asphalt
paving, and other services based in Brooklyn, Iowa is running all of its diesel construction equipment on
biodiesel blends. The Des Moines Metro Division uses B5-B20 blends in about 100 pieces of diesel
equipment. “We are really pleased,” said Curt Manatt, Vice President. “We haven’t had any fuel-related
problems with our equipment since switching to biodiesel. In fact, at first I didn’t even tell our mechanics
that I had switched fuel because I wanted to see if they noticed a difference. They didn’t notice at all.”
North Bay Construction is a general engineering contractor specializing in grading, paving and
underground utility work, based in Petaluma, California. The company began using B20 in about a dozen
pieces of diesel equipment in June, 2006. They plan to begin using biodiesel blends in their entire heavy
equipment fleet (200 pieces) later this year. “We feel good about moving to a cleaner fuel that is
produced domestically and thus will provide a more secure source of energy,” said North Bay
Construction President & Owner, Steve Geney. “We believe our example can be a model for the industry
and are very excited about making the full switch to biodiesel in the coming months.”
