1 CARB Rule Changes- Affects on the Automotive Repair Industry Virginia St. Jean, CIH Industrial Hygienist/DPH Green Programs Manager SF Hazardous Materials Unified Program Agency

2 SFDPH Clean and Green Program Launched in 2001 as pilot award program Compliance excellence Pollution prevention Toxics reduction Auto Repair and Maritime sector only 5/17/2012 Virginia St. Jean 2

3 SFDPH s INTEREST Develop industry specific resource guides to provide latest toxics and compliance tips Serve roll as non-biased information resource- compliance, greener products/methods 5/17/2012 Virginia St. Jean 3

4 Why Automotive Sector? Interest from industry/businesses Toxics/green washing concerns Businesses already well associated Requested information on ingredients of concern in new aerosol formulations after Dec /17/2012 Virginia St. Jean 4

37 What to do now? AEROSOL CLEAN OUT DAY!!! Use up old products, recycle empties Recycle (non-empty) aerosols as Universal Waste Purchase only CA compliant aerosols Avoid ingredients of concern Keep staff informed of your needs/choices for a safer shop Use refillable containers 5/17/2012 Virginia St. Jean 37

38 What to do now? Use product only for intended use Provide extra training for users Work closely with vendors for the right product Talk to other shops/associations- survey others on best ways to use new products Think outside the box- is there a different way perform the maintenance or repair? 5/17/2012 Virginia St. Jean 38
