Instructions for filling in the Emission Test Template

This Information Collection Request (ICR) spreadsheet is intended to collect information about emission data from fossil fuel 

burning power plants and which test methods were used to do so for cases where the test methods are not currently 

supported by the Electronic Reporting Tool (ERT). This spreadsheet should only be used if the method is not in the ERT or if

you do not have access to a lab which performs methods that are in the ERT. You must complete at least 3 separate runs or 

sampling events for each of the requested constituents. This spreadsheet is intended to be used for one boiler of one 

facility. Data for multiple boilers should be handled by using separate copies of this spreadsheet. Fields shaded in yellow 

are required. All cells that are shaded in green are populated using drop-down lists. You do not need to populate cells 

shaded in gray, as they are automatically populated from the Boiler Information worksheet. Please name each resulting 

spreadsheet with the following naming convention: [FacilityID]_Unit_[BoilerID]_EmisTestMethods.xls (example: 

8100_Unit_2_EmisTestMethods.xls).

Please refer to the following steps when using these spreadsheets.

Boiler Information Worksheet

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

2. Please enter the control device configuration.

Emission Data Worksheets

The emission data worksheets are provided for each constituent or constituent family required for this analysis. On each 

spreadsheet, you must enter boiler operating information during sampling, fuel input information, and emission test results.

There are generally 1 to 3 emission test results records to be entered depending on the constituent or constituent family. 

For example, CO only requires 1 record with 3 sample events, while Mercury requires that you enter both Hg0 and Hg+2, or if 

the Ontario-Hydro Method was used, you would need to enter Hg0, HgP, and Hg+2. However, both the Speciated Volatile 

Organic HAP and Speciated Semi-Volatile Organic HAP worksheets allow you to use a drop-down provided in the Constituent 

field to define as many records as needed to record each HAP that you have results for. General instructions follow for 

these worksheets:

Boiler Operation Information

1. Please provide the values of all requested parameters for each of test run/sample.

2. Please provide any other supporting information or comments in the Other Supporting Information field.

Fuel Information

1. Please enter what types of fuel are being used in your boiler using the drop-downs in the Fuel Type Selection field. You 

may enter up to 4 fuel types. If you are not burning one or more of the fuel types entered in one or more samples, then 

enter an input rate of zero. 

2. Please enter the unit of measure using the drop down provided.

3. Please enter the test method used to determine the fuel input rate.

4. Please provide any other information that you feel may be important in the Other Supporting Information field.

Emission Data

1. Some constituents ask for the emission rate results of each run in two different units of measure, while others do not. If 

emission rate results are requested in two different units of measure (ex. lb/MMBtu (Pounds per million BTU) and ppmvd @ 

7% O2(parts per million by volume dry basis at 7 percent oxygen)), you are required to provide both.

2. Please provide the test method used. This may or may not match the example given in the Test Method Used field. 

Please ensure that the name includes the owning organization of the test method (ex. U.S. EPA Method 0010).

3. Please provide any other information that you feel may be important in the Other Supporting Information field.

4. If data sheets and QA/QC documentation tables are provided for the test method you are entering data for please also 

enter these data.
