35Combined SO2 + NOx Emission Rates from Coal Plants - Lb/MWH
U.S. Coal Plant Average 14.83 Lb/MWH
CPS
CPSFuture
Note: 16 of the 100 largest generating companies do not have any coal fired generation
CPS Seeks Public Input
• Established Southeast Quadrant Community Advisory Group (SEQCAG) in October 2002.
• SEQCAG issued report and list of issues in April 2003, continues to meet on a quarterly basis.
• CPS Board of Trustees endorsed management’s commitments to SEQCAG, added more requirements and approved going forward with project in June, 2003.
CPS’ Key Environmental Commitments to the Community
• Use BACT on new unit at a minimum • 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• 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
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: 9,800 BTU/KWH• Proposed Permit Levels (annual averages)
