To the mixed reaction of business people who will be affected by it, Irvine officials Tuesday formally announced their intention to help protect the planet's ozone layer by restricting the use of solvents and other compounds. 

Although other cities, including Los Angeles, have banned the use of plastic foam containers that have chlorofluorocarbons, or CFCs, Irvine's proposed law goes after virtually all "ozone-depleting compounds." 

"We think It is the most far-reaching ordinance in the United States, and we think it will set the standard nationally and globally," Irvine Mayor Larry Agran said at a news conference Tuesday.
