# Gail,
You are the first person to have raised this point and I agree with everything you say in your message below. The answer to your question is provided in the Great River Energy (GRE) BART Analysis on the Appendix A-14 page (attached) from the 2/27/07 version. The page documents the Cost of Flue Gas Re-Heating (Thermal Oxidizer) at $19,017,610. Unfortunately, that detailed page does not appear in the final (12/12/07) version of the GRE analysis.
The $19,017,610 for flue gas reheating plus the $37,136,403 is $56,154,013, which matches the total cost we used from the SCR cost summary page in Table A-13. I apologize for any inconvenience the omission may have caused you. Please let us know if we can be of further assistance. Thanks,

Hi Tom, I am having trouble reconciling the total annualized cost for SCR in Appendix C.2 of the RH SIP for Coal Creek. In the company's December 2007 BART report there is a summary table in Appendix A from which I believe you got the figures for the State's BART determination in Appendix B.2 of the RH SIP. All the numbers in the company's summary for other control technologies seem to match up with the subsequent tables that break down the cost analyses in their Appendix A except SCR. There are two annualized cost totals for SCR in Table A-13 21,379,562 and 37,136,403 (includes lost fly ash sales). The figure reported in the summary is $56,150,000; can you help me figure out how to get to that figure? I may not be seeing an updated supplemental report or something along those lines.
Thanks! Gail
