How will we know that copper isnt being replaced with something that creates its own set of environmental problems?
• A: To avoid creating another environmental or health problem, SB 346 prohibits all but de minimis use of cadmium, hexavalent chromium, lead, mercury, and asbestiform fibers in friction materials, all substances known to cause environmental and/or health problems. The legislation also calls for monitoring of nickel, zinc, and antimony, substances that may be used in some brake formulations but at levels that are not currently viewed as a source of environmental or health problems. If the use of nickel, zinc and antimony in friction materials increases by more than 50%, SB 346 requires DTSC to complete scientific studies to determine whether a maximum concentration of any of these materials is needed.
