NOTES:

Go to

"**S:\ A dmin\ A** **-A ir\ Plant 9 NOx REPORTS** " and open the current month file, i.e. "**2004-01 Jun - lb-day NOx Plant 9.xls** This is the report form that is submitted to BCAA each month before the 10th.

Go to

"**R:\ Stacks\ Plant9\ Reports\ 2004 1st Half Year**" and open the current month CEMS data summary, i.e. "**TJK 2004 -06 June CEMS datalog - Plant 9 xls** This is the data management file used to summarize CEMS data from the datalogc files, to do hourly and daily

averages, and to identify calibrations and down time.

Go to

"**P:\Citect\User\P9_reprt**" and copy the"**datalogc.dbf**"file (current date and time to the minute) and copy it to "**R:\ Stacks\ Plant9\ Reports** This is the raw data file from the Plant 9 CEMS data recorder. Don't open the original for fear of causing it to stop recording.

Open the "**datalogc.dbf**" file copy and copy

the first 3 columns (date, time, ppm NOx) to

"**R:\ Stacks\ Plant9\ Reports\ 2004 1st Half Year\ TJK 2004 -06 June CEMS datalog - Plant 9.xls**" Do a save on the CEMS data file with new data and close the datalogc file.

Now manage the CEMS data by reviewing for missing 2-minute interval readings, shutdown periods, questionable readings. Copy the hourly

average and 3-hour average formula cells down to each xx:00:xx hour. Copy the dailly

average NOx formula down to the last cell of each day

. **Enter a 1, 2, 3, or 4 in column "J" for (1) invalid readings, (2) excess emissions, (3) plant down, or (4) daily auto calilbration.** When finished and all calibrations and daily averages have been calculated, save the document.

Now open the "**S:\ A dmin\ A** **-A ir\ Plant 9 NOx REPORTS** ", "**2004-01 Jun - lb-day NOx Plant 9.xls**" andenter the daily average NOx ppm readings

The daily

nitric acid production summary is located at "S:\ OPER\ EXCEL\ ops\ daily reports\ Daily

2004" Go to

"**S:\ OPER\ EXCEL\ ops\ daily reports\ Daily 2004**" and record or copy the daily nitric acid production for Plant 9. Enter the daily

production numbers into the tons/day column on the monthly report.

When the monthly

NOx report is finished save a copy to for use the next month. Update the first day and month summary

to 2004. You are done with the Monthly NOx report.

Now, go back to "**R:\ Stacks\ Plant9\ Reports\ 2004 1st Half Year\ TJK 2004 -06 June CEMS datalog - Plant 9.xls** Transfer the total plant operating hours, CEMS operating hours, and excess emission hours to the AOP semi-annual monitoring report at

"**S:\ A dmin\ Environmental\ A** **ir\ BCA A** **Title V Semi-annual Monitoring Reports\ 2004 Jan to Jun semi-annual monnitoring report\ \ 2004 1st CEMS EXCESS EMISSIONS and MONITORING REPORT.xls"** 9/23/2011 PLANT 9 Monthly NOx Report Page 2
