3 firms pay more than $1.75 million in penalties to state Air Resources Board

The California Air Resources Board has announced combined penalties of more than $1.75 million against three companies doing business in the state.

ARB said San Antonio-based Tesoro Corp. has paid $1.01 million for violations of California’s reformulated gasoline regulations. ARB said Tesoro supplied gasoline not complying with state requirements from two Tesoro refineries and one terminal for more than 52 days. About $760,500 will go to California’s Air Pollution Control Fund, and $253,500 will go to fund retrofits of California school buses with diesel-particulate filters.

ARB said Riverside-based K&N Engineering Inc. has agreed to a $521,000 settlement to resolve alleged violations of the California Health and Safety Code related to advertising and sales of illegal, aftermarket, automotive performance parts in California.

State investigators said K&N sold performance parts that had not received exemptions from California’s emissions control system anti-tampering laws. California law prohibits advertising, selling or installing parts that modify vehicle emissions control systems unless the parts are proved to not reduce the effectiveness of the systems.

Navistar Inc., the Illinois-based manufacturer of commercial trucks, buses, defense vehicles and engines, has paid $250,000 in penalties to ARB for failing to follow proper testing procedures for one of its diesel-exhaust filters, as required by state law.
