CLEAN TRUCKS: A ban on old and dirty diesel rigs at the Los Angeles and Long Beach ports went into effect, with port officials reporting they did not have to turn away many trucks. The $1.6 billion Clean Trucks Program aims to reduce diesel by 80 percent within five years, starting with a ban on trucks built before 1989. By 2012, all trucks entering the ports will be required to meet 2007 vehicle emission standards. The American Trucking Association continues to pursue a lawsuit against the ports on some provisions of the program, but failed to get an injunction stopping it from going into effect Oct. 1.

PROXY WAR: International Rectifier Corp. officials are urging shareholders to ignore a sweetened $23 a share tender offer launched last week by rival chip maker Vishay Intertechnology Inc. The cash offer values the El Segundo power management chipmaker at about $1.7 billion. Vishay, based in Malvern, Pa., also has nominated a slate of directors for election at the company's annual meeting on Oct. 10. International Rectifier said that Vishay has yet to secure commitments to fund the takeover.
