### Instructionsfor filling Mercury EmissionReporting Information

This spreadsheet is intended for you to enter informationabout Historic Mercury emissionsat your facility for each boiler, based on reading from continuous emissionsmonitoring systems(CEMS) data. Please provide both your boiler's hourly data and daily data. Fields required in each worksheetare highlighted in yellow. Gray cells are automticallyfilled for you. Green cells require you to choose a value from a drop

-down box. Pleasename each resulting spreadsheet with the following naming convention:[FacilityID]_Unit_[BoilerID]_HgCEMS.xls(example:8100_Unit_2_HgCEMS.xls).

Unit Information Worksheet

1. Boiler informationincluding EIA Facility Code, Facility Name, Boiler ID, and Unit Type are required regardless of whetherother information is provided on this worksheet. 2. Mercury Emission Limits. Please provide units of measure in the columns that followsthe mercury emissionlimit values.

CEMS Data Hourly

The CEMS Data Hourly worksheet is based upon Pt. 75 App. F or 40 CFR CH I (7

-1

-07Edition). The basic entries are based on Equation F

-28 and F

-29. There are a few additional entries required. You are required to report historic mercury emissiondata for the following species of mercury, if recorded by your CEMS: Hg, Hg0

### , and Hg

1. Please enter the collection date (MM/DD/YYYY)and collection hour (HH24:MM)of each data record. 2. Please enter the total Hg emissions(ounces), total Hg fluegas concentration,concentration unit of measure, and the

averagehourly Hg emission factor for each species of Hg (lb/MMBtu). 3. Please provide the fluegas flowrate (scfh), fluegas temperature(°F),unit or stack operating time (hr), and moisture fraction of the stack gas. 4. Please enter the heat input (MMBtu/hr),average load for the hour of the reading (MW Gross), and the F used).

The CEMS Data Daily worksheetrepresents data rolled up from the hourly values, as appropriate. Please provide the followinginformation:

1. Please enter the collection date (MM/DD/YYYY). 2. Please enter the total Hg emissions(ounces), total Hg fluegas concentration,concentration unit of measure, and the

averagedaily Hg emissionfactor for each species of Hg (lb/MMBtu). 3. Please enter the average mercury emission rate (ounces/hour). 4. Please provide the average fluegas flowrate(scfh), average fluegas temperature(°F),unit or stack operating time (hr), and average moisture fraction of the stack gas. 5. Please enter the average heat input (MMBtu/hr),average daily load (MW Gross), and the F
