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 s

handled by using separate spreadsheets. Please name each resulting spreadsheet with the following naming co

[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 tabs at the 

the page. Please begin with the Boiler Information tab, then proceed to the Hourly tab for a given constituent, an

the daily tab for the constituent. Yellow highlighted column headers mean that the field is required. Gray highlig

do not require data entry, as they are filled in automatically from the information that you input on the Boiler Info

worksheet. Green highlighting in a cell indicates that it should be populated using a dropPlease refer to the following steps when using this spreadsheet. CEM data for each constituent are collected on t

worksheet. Additionally, your are asked to provide boiler specific information about the control device configurat

fuel mix during the test .

Boiler Information

1. Please enter the the EIA Facility Code, Facility Name and Boiler ID of your boiler on the Boiler Information work

2. Please enter the typical control device configuration and operating rate used during the 30

Information worksheet in columns D and E.

3. Please enter information about the typical fuel mix for the boiler in columns F through U on the Boiler informa

worksheet. You may specify up to 4 different fuels used in the mix, using drop-down boxes, as well as fuel input r

units. The unit choices are contained in a drop-down box. If you choose "other" as your fuel, you must specify th

"Specify if Fuel is other" column.

4. If applicable, please enter Operational Upsets or other Important Conditions Occuring During 30 Day Period on 

Information worksheet in column V.

CEM Hourly Average Results

There are 4 hourly averge results worksheets in this spreadsheet, inlcuding CO, NOX, SO2, and Hg. There are 720 r

that you are entering CO, NOX, SO2, and Hg data in the appropriate worksheets. As you scroll to the right on each 

screens, you will find text boxes, which expand as you type, requesting that you provide the equations/descriptio

process used to convert to both lb/MMBtu and ppmvd @ 7% O2.

1. In the red box, please provide the date and hour of each average, along with the converted values for both lb/

CEM Daily Average Results
There are 4 daily averge results worksheets in this spreadsheet, inlcuding CO, NOX

, SO2, and Hg. The intent of this 

is for you to provide daily average data based on the hourly data that you provided for your boiler, in both lb/MM

ppmvd @ 7% O2. Please ensure that you are entering CO, NOX, SO2, and Hg data in the appropriate worksheets.
