cps plans to add a new coal unit
CPS Plans to Add a New Coal Unit
  • Type : Pulverized Coal, Hybrid Pressure(2520 psi, 1050 oF, 1050 oF)
  • Location: Calaveras Lake
  • Fuel: Powder River Basin Coal
  • Size: 750 MW
  • Heat Rate: 9,300 BTU/KWH
  • Proposed Permit Levels (annual averages)
    • SO2 - 0.06 Lb/MMBTU (wet limestone scrubber)
    • NOx - 0.05 Lb/MMBTU (SCR)
    • PM - 0.022 Lb/MMBTU (fabric filter)(collectibles + condensables)
    • Hg - 0.00002 Lb/MWH (oxidation and/or sorbent injection)
summary of cps licensing approach for new coal unit
Summary of CPS Licensing Approachfor New Coal Unit
  • Began with some of the lowest emission rate coal units in the U.S.
  • Exemplary emissions performance of corporate coal fleet
  • Began strategic energy planning process well in advance of need. CPS strategic energy planning project has been in progress 5+ years now. New coal unit a major element of the process. Board adopted strategic energy plan on June 30, 2003
  • Involved the public early on – Public involvement began 3.5 years ago
summary of cps licensing approach for new coal unit1
Summary of CPS Licensing Approach for New Coal Unit
  • Went well beyond Best Available Control Technology (BACT) levels for new coal unit
  • Provided offsets for emissions from the proposed coal plant
  • Applied Mercury Maximum Available Control Technology (MACT) as originally proposed
  • Added renewables and conservation to the strategic energy portfolio
  • Took, and continue to take, message to the community
sample of public involvement
Sample of Public Involvement
  • Citizens Advisory Committee (CAC)
    • Frequent updates since 2001
  • Southeast Quadrant Citizens’ Advisory Group
    • More than 20 meetings since October 1, 2002
  • Environmental Health Oversight Committee
    • 11 meetings since December 2, 2003
  • All these groups continue to meet for periodic updates
  • Public has provided substantive input
    • CPS adopted public input as commitments to Community
sample of public involvement1
Sample of Public Involvement
  • Five Town Hall Meetings
    • 4/6/04 Ed White Middle School
    • 4/8/04 John Marshall High School
    • 4/13/04 Sam Houston High School
    • 4/15/04 John F. Kennedy High School
    • 4/27/04 East Central High School
  • TCEQ Public Meeting
    • December 16 2004
timeline of major events
Timeline of Major Events
  • Spring 2001 – Internal committee Comprehensive Energy Resource Coordination and Implementation Team (CERCIT) established to identify energy options and develop strategicenergyplan
  • October 2002 – Established Southeast Quadrant Citizens Advisory Group (SEQCAG)
  • June 30, 2003 – CPS Board gave approval to proceed with the strategic energy plan including the new coal unit
  • November 21, 2003 – Permit application submitted to TCEQ
timeline of major events1
Timeline of Major Events
  • January 12, 2004 – TCEQ finds permit application to be administratively complete
  • November 5, 2004 – TCEQ issues draft permit. This process took more than 1 year from initial application and the draft permit had only minor changes from the application
  • December 16, 2004 – TCEQ holds public meeting on draft permit at East Central High School
  • May 18, 2005 – Contested hearing – determination of party status and adoption of schedule
timeline of major events2
Timeline of Major Events
  • May 18–Sept 12, 2005Discovery and Deposition period
  • Sept 30, 2005CPS files its direct case and provides witness list
  • Oct 24, 2005Opposition files its direct case and provides witness list
  • Nov 9, 2005Objections to direct cases due
  • Nov 28, 2005Prehearing conference
  • Dec 5–9, 2005Hearing on merits
  • Jan 16, 2006File closing arguments and briefs
  • March 27, 2006Record of Decision (expected)
  • Dec 5, 2006 – Hearing settled!
  • Dec 28, 2006 – Permit Issued!
slide11

What were the Issues of Concern?

Based upon comments by protestants

  • Project not Needed
    • Conservation/Renewables are adequate to meet needs
  • TCEQ should Regulate CO2
    • Permit does not propose CO2 limit
    • Applicant has not identified Best Available Control Technology (BACT) for CO2
  • BACT Issues
    • Integrated Gasification Combined Cycle = BACT
    • Mercury emissions are too high
  • Health Impacts
    • Environmental Justice issues
  • Visibility Issues
    • Visibility impact on Big Bend National Park
    • Increment Consumption at Big Bend
cps key environmental commitments to the community
CPS’ Key Environmental Commitments to the Community
  • Use of Best Available Control Technology on new unit
  • Enhance coal yard environmental controls
  • Reduce existing emissions so there will be no net increase in aggregate emissions as a result of new unit going on-line
  • 10% renewables commitment by 2015 (~ 600 MW)
  • Increase spending on conservation programs
  • Enhanced air quality monitoring program around plant
  • Community environmental health awareness program
  • New Unit will be brought under Ch. 117 NOx cap
  • Additional emissions reductions from existing units so there will be a substantial net decrease in aggregate emissions after new unit goes on-line
