### Instructionsfor Completing the Process Data Template

This template is to be used to record the 30 daily averages of specific process data required by the ICR. The ERT does not have the capability to store these daily averages. This spreadsheet included 4 separate surrogate worksheets,in case the boiler tested is tested for all surrogates at 4 different dates.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. yelloware required (if applicable to your boilers' operation). You do not need to populate cells shaded in gray, as they ar automaticallypopulated from the Boiler Information worksheet. Please Do Not modify the structure of this spreadsheet by adding or subtracting rows, columns, cells. Please name each resulting spreadsheet with the following naming convention:[FacilityID]_Unit_[BoilerID]_Processdata.xls(example: 8100_Unit_2_Processdata.xls).

Please refer to the following steps when using these spreadsheets.

BoilerInformation Worksheet

Pleaseenter the EIA Facility Code, Facility Name and Boiler ID of your boiler on the Boiler Informationworksheet.

ProcessData Worksheets

Please use one process data worksheetfor each HAP surrogate even is simultaneous testing of different HAP surrogates was done.
