A few errors have been found in the original cuecost.xls and cuecost2.xls
Excel workbooks.  These errors have been corrected or minor revisions made
resulting in the Excel workbook called, "cuecost3.xls."  

Cuecost3.xls is considered to be a useful tool, and may be used to estimate
the costs of coal-fired utility boiler controls for sulfur dioxide, nitrogen
oxides, and particulate matter, but the user should be aware that this
version (cuecost3.xls) is now considered to be a beta test version of the
workbook. 

If you have questions or problems with this model or the documentation, please call 
Norm Kaplan (EPA) at (919) 541-2556.

Note from CATC Webmaster:

A slight error was noticed in the original CUECost Excel spreadsheet (the word "DRAFT"
was printed on one page).  I have replaced the original file with an updated file,
included in the ZIP files, called CUECOST2.XLS

The CUECost economic analysis workbook is a Y2K-compliant system designed to produce 
rough-order-of-magnitude cost estimates (+30%/-30% accuracy) of the installed capital 
and annualized operating costs for air pollution control (APC) systems installed on 
coal-fired power plants to control sulfur dioxide, nitrogen oxides, and particulate 
matter. The workbook is capable of calculating estimates of an integrated APC system or 
individual component costs for various APC technologies currently used in the utility 
industry.  The technologies included in the workbook are:

Flue Gas Desulfurization (FGD) = Limestone with Forced Oxidation (LSFO)
Lime Spray Drying (LSD)
Limestone with Dibasic Acid (LSDBA)

Particulate Matter Removal = Electrostatic Precipitator (ESP)
Fabric Filter (FF)

Nitrogen Oxide Control = Selective Catalytic Reduction (SCR)
Selective Non-Catalytic Reduction (SNCR)
Natural Gas Reburning (NGR)
Low NOx Burners (LNB)


The CUECost system is presented as four files:
* CUECost Users' Manual - three zipped files in Adobe Acrobat
- User's Manual main text and Appendixes A through D
- Appendix E
- Appendix F
* CUECost Workbook - a Microsoft Excel set of spreadsheets.
