  1. California Environmental Protection Agency Air Resources Board Ozone Transport Regulations Public Workshop January 28, 2003

  2. Workshop Agenda • Welcome and Introductions • Staff Presentation • Background • Concepts Under Consideration • Proposed Schedule • Public Comment and Discussion

  3. Purpose of Workshop • Inform public about plans to amend transport regulations • Staff currently scheduled to recommend amendments to Board May 2003 • Discuss concepts under consideration • Provide opportunity for public input

  4. Background

  5. Transport Mitigation Includes: • Air Quality Attainment Planning • Transportation Planning • Land Use Planning

  6. California Clean Air Act (CCAA) Requirements ARB is required to: Assess Transport • Identify transport couples • Assess relative contribution of upwind emissions on downwind ozone concentrations Mitigation • Establish mitigation requirements

  7. ARB Transport Activities • Transport assessments - 1990, 1993, 1996, 2001 • Mitigation requirements established in 1990 and amended in 1993 • Board directed staff to strengthen mitigation requirements- April 2001 • Workshop on mitigation strategies - June 2001 • Report to Board- July 2001

  8. Current Mitigation Requirements • Sufficient measures based on modeling • Best Available Retrofit Control Technology (BARCT) on stationary sources

  9. Need for Review • Board direction to strengthen mitigation regulation • Address equity issue • Some upwind areas have less stringent NSR permitting programs than their downwind neighbors • Acceleration of BARCT achieved • Timely implementation of innovation and technology

  10. Concepts Under Consideration

  11. Concepts Under Consideration 1. New Source Review Program Require equal “no net increase” thresholds for upwind and downwind areas 2. All Feasible Measures Provide timely and ongoing assessment of All Feasible Measures

  12. Concept 1:Equal New Source Review (NSR) Program Thresholds

  13. Overview of NSR Program New or Modified Source 1. Apply BACT * 2. Reanalyze potential to emit 3. Offset emissions (no net increase) YES Do Permitted Emissions Exceed Threshold? NO * Changes are not being proposed to BACT thresholds Comply with Existing District Rules

  14. Why Require Equal“No Net Increase” Thresholds? • Current NSR threshold levels based on State ozone classification (BACT & “no net increase”) • NSR requirements not currently part of transport regulation • Different thresholds create inequity among transport couples • Differences exist in “no net increase thresholds” • Regional impact Bay Area/Sacramento/San Joaquin Valley

  15. “No Net Increase” Thresholds

  16. Concept 2:Facilitate Expeditious Adoption of All Feasible Measures

  17. All Feasible Measures Requirements Under CCAA • CCAA’s Requirements • Achieve 5% reduction in district-wide emissions OR include all feasible measures in clean air plan • District reviews every 3 years and submits to ARB for approval • ARB provides technical assistance, guidance documents, and recommendations

  18. Concept for All Feasible Measures • Ensure timely implementation of CCAA requirements already applicable to upwind districts • Require the most effective strategies within district’s legal authority • Incorporate mechanism for ongoing assessment of all feasible measures • Maintain both NOx and ROG pollutant strategies

  19. Proposed Schedule

  20. Proposed Schedule • Public Workshop January 28, 2003 • 2nd Public Workshop February/March 2003 • Stakeholder Meetings On going • Staff Report Early April 2003 • Public Hearing May 22-23, 2003* *Tentative Date
