  1. IMPLEMENTATION OF SENATE BILL X1 28 & UPDATE OF POWER PLANT SITING GUIDANCE Workgroup Meeting August 3, 2001 Air Resources Board California Environmental Protection Agency

  2. Purpose of Today’s Meeting • Discuss ARB’s approach for Electrical Generation Retrofit Regulation and Guidance update • Solicit members for workgroup • Highlight important dates for regulation/guidance • Set workgroup meeting dates

  3. Focus for Today • Statewide regulation and schedule for retrofitting electrical generating facilities • Update “Guidance for Power Plant Siting and Best Available Control Technology”

  4. Presentation Overview • Retrofit Regulation: • Background • Scope of regulation • Power Plant Guidance Update: • Current Guidance BACT emission levels • Areas of possible change • Low emission measurement • Regulation/Guidance Workgroup: • Workgroup’s role • Tentative regulation & workgroup schedule

  5. Statewide Retrofit Regulation: Background

  10. Statewide Retrofit Regulation:Scope

  11. Scope of Regulation • Applicability • 1 MW and greater • Supplies power to the grid • Includes: • Prime reciprocating engines • Peakers • Boilers • Qualifying Facilities (Q.F.’s) • Renewables • Other

  12. Scope of Regulation(continued) • Pollutants: • All criteria pollutants - NOx, CO, VOC, PM10, SOx • Emission limits: • Based on class/category of source (i.e., combined-cycle turbine, natural gas-fired boiler, wood-fired boiler, landfill gas-fired ICE) • Incentives for zero emission technologies

  13. Scope of Regulation(continued) • Banking criteria • TBD • Timelines for implementation of retrofits • TBD • Exemption for repowers

  14. Retrofit Starting Points • ARB guidance • RACT/BARCT emission limits currently in place • BACT emission control techniques • District Rule and Regulation commitments

  15. Emission Reduction Credit Bank • Two Step Process: • 1) Establish bank tracking system • 2) Fund the bank from emission reductions achieved from regulation

  16. Update to the Guidance for Power Plant Siting and Best Available Control Technology

  17. Current BACT Guidance:Achievable Emission Levels for Simple-Cycle Configuration • 5 ppmvd NOxat 15% O2, 3-hr rolling average • 6 ppmvd CO at 15% O2, 3-hr rolling average • 2 ppmvd VOC at 15% O2, 3-hr rolling average, or 0.0027 lbs/MMBtu • Case-by-case determination for industrial frame turbines

  18. Current BACT Guidance:Achievable Emission Levels for Combined-Cycle and Cogeneration Configuration • 2.5 ppmvd NOxat 15% O2, 1-hr rolling average, or 2.0 ppmvd at 15% O2, 3-hr rolling average • 6 ppmvd CO at 15% O2, 3-hr rolling average • 2 ppmvd VOC at 15% O2, 1-hr rolling average, or 0.0027 lbs/MMBtu

  19. Current BACT Guidance:Achievable Emission Levels for SOx and PM10 • For PM10 and SOx, emission limits corresponding to combustion of natural gas with total sulfur no more than 1 grain/100 SCF • For SOx, equivalent to no more than 0.55 ppmvd @ 15% O2

  20. Areas of Possible Change • Simple-cycle power plants: • Lower NOx levels for aeroderivative turbines • Definitive NOx BACT for industrial frame turbines • Combined-cycle power plants: • Lower NOx BACT

  21. Low Emission Measurement Committee • Investigating problems with low NOx measurement in gas turbine exhaust • To develop a test method to more accurately quantify low NOx emissions from gas turbines • University test study quantifying sources of error in NOx measurement methods • South Coast AQMD low emission performance testing on SCONOx • Efforts of other organizations

  22. Regulation/Guidance Workgroup

  23. Tentative Regulation and Guidance Schedule • Mail draft regulation November 9, 2001 • Statewide Public Consultation Workshops • Sacramento December 11, 2001 • Los Angeles December 12, 2001 • Eureka December 14, 2001 • Board Meeting April 25, 2002

  24. Workgroup’s Role • Identify stakeholders’ perspectives • Exchange technical information • Provide forum to brainstorm draft concepts

  25. Workgroup Schedule • Initial Workgroup Meeting August 3, 2001 • Workgroup Meeting September 13, 2001 • Workgroup Meeting October 4, 2001
