Unocal Settles With Air Resources Board: The Los Angeles-based oil company agreed to pay $2,088,666 in cash and to sponsor various clean-air projects to resolve the air board’s complaint that it had failed to add enough detergent to its gasolines to meet state rules. Unocal is required to spend most of the settlement money on improving its bulk terminal facilities “to help assure future compliance with ARB clean-gasoline specifications,” the agency said in a statement. Unocal must also buy and take off the road 167 vehicles built before 1975 without receiving the clean-air credits ordinarily due with such purchases. The company must pay $345,666 to the state and $50,000 to a scholarship fund at California Polytechnic State University, San Luis Obispo.
