Two Los Angeles city councilmen, a Santa Monica councilman and the West Hollywood mayor have called for enactment of local laws requiring deposits on beverage containers, if the Legislature does not pass a statewide "bottle bill." Nine states have such laws. Los Angeles Councilman Zev Yaroslavsky said he has introduced an ordinance that would require a nickel deposit on beer and soda containers. Appearing with Yaroslavsky at a news conference were Councilman Howard Finn, Santa Monica Councilman Alan Katz and West Hollywood Mayor John Heilman. Katz and Heilman said they are drafting ordinances that would take effect when 10% to 20% of the state or county population is covered by a bottle bill. "The larger the population, the better these bills will work from an economic point of view," Heilman said.
