1. 1 ITSA Meeting April 2, 2004 San Diego Thermal Spraying in California

2. 2 Improve air quality & protect public health –Coordinate local, state, and federal efforts to attain air quality standards –Legal authority to control emissions from Vehicles Engines/Equipment (e.g. lawnmowers) Fuels Consumer Products Air Toxics Sources ARB’s Role

3. 3 Identification of Toxic Air Contaminants Airborne Toxic Control Measures Air Toxics “Hot Spots” (AB2588) inventory and fees Neighborhood Air Monitoring Risk Reduction Guidelines ARB’s Toxics Program

4. 4 Air Toxics Regulations FEDERAL - EPA MACT/NESHAP Large Sources Area Sources STATE - ARB ATCMs Large Sources Small Sources Area Sources LOCAL - Air Districts Local Rules Large Sources Small Sources Area Sources

5. 5 2002: ARB began Thermal Spraying project Goals: –Characterize thermal spray industry in CA –Quantify toxic air emissions –Determine whether health risks exist ARB’s Thermal Spraying Project

6. 6 2003 Survey of Thermal Spraying Material Manufacturers 2004 Survey of Thermal Spraying Facilities Air Dispersion Modeling Health Risk Assessment Possible ATCM ARB’s Thermal Spraying Project

7. 7 Key Findings from Surveys: –103 tons of thermal spraying materials sold in CA in 2002 –Materials contained 18 tons of chromium and 34 tons of nickel –The aerospace industry uses more than 1/3 of the materials –CA has 46 active thermal spraying facilities –Most facilities have control devices –More than 1/2 of facilities use chromium-containing materials ARB’s Thermal Spraying Project

8. 8 Board Member request Potential use as replacement for hard chromium electroplating Community Health Program Environmental Justice concerns ARB’s Thermal Spraying Project

9. 9 Hexavalent chromium is very toxic –Small quantities can increase cancer risk substantially Nickel can cause cancer and other health effects ARB’s Thermal Spraying Project

10. 10 ARB Air Districts Thermal Spraying Material Manufacturers Industry Trade Organizations (ITSA) Thermal Spraying Facilities Other Interested Stakeholders ARB’s Thermal Spraying Project

11. 11 Conduct Surveys Compile Scientific Research Develop Emission Inventory Perform Air Dispersion Modeling Estimate Potential Health Risks Determine if ATCM is needed ARB’s Thermal Spraying Project

12. 12 If ATCM is Needed: Workshops Conference Calls Public Opportunity to Comment Board Hearing Formal Regulatory Process ARB’s Thermal Spraying Project

13. 13 April Workshop May Draft Regulatory Language September Proposed Regulation and Staff Report Available Public has 45 days to comment October Board Hearing ARB’s Thermal Spraying Project

14. 14 South Coast AQMD –Evaluating Need for Rule for Thermal and Conventional Spraying of Hexavalent Chromium-Containing Compounds –22 Thermal Spraying Sources –100+ Conventional Spraying Sources –SCAQMD Working Closely with ARB to Ensure Proposed Rule is Consistent with ATCM –Opportunity for Public Input in June 2004 Activities at Local Districts
