A company fined by the U.S. Environmental Protection Agency for selling an unregistered diesel additive in 2006 now says it has full EPA approval for its product.

Biofriendly Corp., incorporated in Nevada with principal offices in Covina, Calif., has agreed to pay the U.S. Environmental Protection Agency $1.25 million for manufacturing and selling an unregistered fuel additive. EPA officials say this is the largest penalty ever levied for violation of the Clean Air Act's registration requirements for fuels and fuel additives. The consent decree allows Biofriendly to pay a fine for what it calls an "administrative dispute" while admitting no liability.

Biofriendly sold "Green Plus," an unregistered fuel additive it claimed reduced emissions in diesel fuel, between Sept. 2002 and May 2006. When Biofriendly discovered it was in violation, it stopped selling Green Plus domestically.

The company announced Monday that the U.S. Environmental Protection Agency approved new product registrations for its Green Plus liquid combustion catalyst after a two-year review.

Green Plus is added in very small quantities to fuel (diesel or gasoline) in order to "create a more complete, cooler and more linear burn," says the company. According to their web site, the additive works "at the molecular level to slightly 'unbundle' complex hydrocarbon molecule clusters to enable oxygen to reach the fuel and react with the fuel more easily." Green Plus is now available commercially worldwide.
