### Instructions for filling CEMS Information

This Information Collection Request (ICR) spreadsheet is intended to collect CEM data for CO, NO and Oxidized). This spreadsheet is intended to be used for one boiler of one facility. Data for multiple boilers should be handled by using separate spreadsheets. Please rename each resulting spreadsheet with the following naming convention: [FacilityID]_Unit_[BoilerID]_CEMS.xls (example: 8100_Unit_2_CEMS.xls).

This spreadsheet is divided into several worksheets, which may be accessed by clicking on each of the color coded tabs at the bottom of the page. Please begin with the Boiler Information tab, then proceed to the Hourly tab for a given constituent, and then to the daily tab for the constituent. Yellow highlighted column headers mean that the field is required. Gray highlighted cells do not require data entry, as they are filled in automatically from the information that you input on the Boiler Information worksheet. Green highlighting in a cell indicates that it should be populated using a drop

-down menu, which is provided.

Please refer to the following steps when using this spreadsheet. CEM data for each constituent are collected on their own worksheet, which are color coded by surrogate group. Additionally, your are asked to provide boiler specific information about the control device configuration and fuel mix during the test for each surrogate group.

Boiler Information

1. Please enter the EIA Facility Code, Facility Name and Boiler ID of your boiler on the Boiler Information worksheet. on the first row. Note that column D contains each constituent/surrogate group combination being tested, and is color coded to the various hourly and daily data entry tabs. 2. Please enter the typical control device configuration and operating rate used during the 30 Boiler Information worksheet in columns E and F for each constituent/surrogate group combination. 3. Please enter information about the typical fuel mix for the boiler used during the 30

-day test period for each constituent/surrogate group in columns G through V on the Boiler information worksheet . You may specify up to 4 different fuels used in the mix, using drop

-down boxes, as well as fuel input rate and units. The unit choices are contained in a drop

-down box. If you choose "other" as your fuel, you must specify the fuel in the "Specify if Fuel is other" column. 4. If applicable, please enter Operational Upsets or other Important Conditions Occurring During 30 Day Period on the Boiler Information worksheet in column W.

CEM Hourly Average Results

There are 5 hourly average results worksheets in this spreadsheet, including CO, NOX

### , SO 2 

### There are 720 rows for which you may enter data, one for each hour of a 30 day monitoring period. You must enter both the unit of measure on this worksheet from your CEM readout and the converted values for both lb/MMBtu and ppmvd @ 7% O 2 

### . Please ensure that you are entering CO, NOX

Note: To convert from a wet to a dry concentration value, EPA suggests the moisture approximation method in Part 75 (i.e., Appendix A, section 2.1.5, the minimum potential moisture of 3.0 percent or a measured value from the past). Also, the tester can calculate the concentration in units of ppmvd@ 7 percent O2 using the CO2 data. The tester can determine O2 values from the CO2 measurements using Method 3B, equation 3B

Sample Unit Conversion Equation from Hourly Units of parts per million by volume dry basis at 7% O 2 

### (ppmvd @ 7% O 2

### ): Otter Tail's CEMS does not have the capability to convert wet ppm to 7% dry basis. Per guidance given from Jeff of RTI International to Mr. Terry Graumann of Otter Tail Power Company in an email dated April 7, 2010, Otter Tail was to enter data in the units of measure we have and change column headings to reflect those units.EIA
