  1. California Environmental Protection Agency Air Resources Board Public Workshop Airborne Toxic Control Measure (ATCM) for Motor Vehicle and Mobile Equipment Coatings May 9, 2001

  2. Agenda • Introductions • General Information on Toxics Program • Background Information • Summary of Draft Regulation • Project Schedule • Q&A

  3. AB 1807 • Established California’s Air Toxics Program • Established a two-phase process for the identification and control of air toxics

  4. Toxic Air Contaminant (AB 1807) “...an air pollutant which may cause or contribute to an increase in mortality or in serious illness, or which may pose a present or potential hazard to human health.”

  5. Program FrameworkAB 1807 - A Two-Phase Program  Risk assessment - formal identification of toxic air contaminants  Risk management - develop needs report/ control measures

  6. Suspected Toxic Substance OEHHA Evaluates Health Effects Draft Report Public Workshops Scientific Review Panel Public Hearing Board Decision to List as a TAC Steps of Identification Process ARB Assesses Exposure

  7. Assessment of TAC Sources Public Workshops Public Hearing Prioritize Control Options Board Decision to Adopt Control Measure Public Workshops APCDs Implement and Enforce Control Measure Draft Report On Control Measures Steps of Risk Management Phase

  8. Hexavalent Chromium and Cadmium • Hexavalent chromium and cadmium are used in automotive coatings • Used as a color pigment and as a corrosion inhibitor • Emitted as metal particulates

  9. Why Control Hexavalent Chromium ? • Hexavalent chromium is one of the most toxic compounds identified by ARB • Minimal emissions can lead to significant risk • Removal of hexavalent chromium will reduce the need for public notification and risk reduction plans

  10. What are the Current Restrictions on Hexavalent Chromium? • Some air districts have rules that reduce hexavalent chromium emissions • SCAQMD prohibits the use of coatings that contain hexavalent chromium • VCAPCD requires chromium-containing coatings to be sprayed inside a spray booth

  11. Feasibility of Proposal • Alternative coatings are readily available and widely used • Surveys show minimal usage of coatings containing hexavalent chromium and cadmium

  12. Draft Regulation • Applicability • Exemptions • Standards • Compliance timelines

  13. Applicability • ATCM applies to manufacturers and distributors of motor vehicle and mobile equipment coatings • ATCM also applies to auto bodyshops and other facilities that use motor vehicle and mobile equipment coatings

  14. Exemptions • ATCM does not apply to motor vehicle or mobile equipment coatings used outside of California • The exemption does not apply to coatings sold to retail outlets in California

  15. Standards • Coatings containing hexavalent chromium and cadmium cannot be sold in California • No motor vehicle or mobile equipment coating facility may use or possess a coating containing hexavalent chromium or cadmium • Each coating container subject to this rule must be code dated

  16. Timelines • Coatings manufactured before the effective date of the regulation may be sold for six months after the effective date • End users may use non-complying coatings for 12 months after the effective date

  17. Project Schedule • Final Staff Report in early August, 2001 • Board Hearing on September 20-21, 2001 • Office of Administrative Law review completed approximately March, 2002 • Regulation “Effective Date”
