Subject: Encina Power Station - Revised Baseline Emissions

Steve and Camqui:

Enclosed is the revised baseline emissions for the Encina Power Station. I sorry this took me so long to

get to you. I also included the Excel spreadsheet so that you can see how the Rule 69 NOx correction

was done. Please let me know if you have any questions.2002 Operating Year(tons) #1 Nat. Gas #1 Res. Oil #2 Nat. Gas #2 Res. Oil #3 Nat. Gas #3 Res. Oil #4 Nat. Gas #4 Res. Oil #5 Nat. Gas #5 Res.
