### 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.Pleasename each resulting spreadsheet with the following naming

convention:[FacilityID]_Unit_[BoilerID]_Processdata.xls(example: 8100_Unit_2_Processdata.xls).

Pleaserefer 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

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

Notes: Coal Firing Rate is for each of the 5 coal feeders on the unit.

Average Heat Input, Flue Gas Flow Rate, Flue Gas Pressure, Flue Gas Pressure, Flue Gas Sampling Point Temperature, and Flue Gas Carbon Dioxide Content are for the common stack for units 1&2 and are measured bythe CEM. Flue Gas Flow rate is a measured, wet not dry

. Flue Gas Oxygen Content is measured at the economizer outlet and is an averge of several monitors used for control.Daily A verage Process Data for a 30 Day Period Including the Testing Date Synfuel Firing Rate (units)Pet Coke Firing RatePet Coke Firing Rate (units)Coal Gas Firing Rate
