MEMORANDUM 

DATE: May 29, 1987 

TO: Walt Stevenson, EPA/SDB 

FROM: Cecil Stackhouse, Jr. and David White, Radian Corporation 

SUBJECT: Spray Dryer and Continuous Emission Monitoring System 

Reliability at Shiras Steam Plant Unit No. 3 

This memo summarizes the reliability of the flue gas desulfurization 

(FGD) system and continuous emissions monitoring system (CEMS) at the Shiras 

Steam Plant Unit 3. The data analyzed covered two years of operation 

between January 1985 and December 1986. 

The Shiras Power Plant is operated by Marquette Board of Light and 

Power in Marquette, Michigan. Unit 3 is subject to Subpart Da and is rated 

at 44 MWe (approximately 450 million Btu/hour heat input). Unit 3 is a 

pulverized-coal boiler and fires low-sulfur subbituminous coal 

(approximately 1.1 lb SOp/million Btu). The FGD system is a lime spray 

dryer; inlet and outlet S02 levels are monitored using CEMS. Under Subpart 

Da Unit 3 is subject to the 0.6 lb/million Btu heat input and the 70 percent 

S 02 reduction requirement. 

Reliability is defined as the percent of time a system operates 

relative to the amount of time it is called upon to operate. To determine 

the reliability of the FGD system and CEMS at Shiras No. 3, the quarterly 

summary data and the monthly data supplied in two years of Quarterly Excess 

Emissions Reports were used (attached). 

For 1985 and 1986 the boiler operated 15,889 hours or 91% of the time. 

The FGD system operated for 15,588 hours, achieving greater than 98 percent 

reliability during the two year operation period. 

The CEMS consists of a single continuous SC^ and oxygen monitor and a 

data recording system. The CEMS alternately monitors at the inlet and 

outlet of the FGD system. It was assumed that when the monthly data sheets 

showed a daily calculated percent reduction value, the CEMS was operating. 

Progress Center/3200 E. Chapel Hill Rd./Nelson Hwy./P.O. Box 13000/Research Triangle Park. N.C. 27709/(919)541-9100 
Based on these data, the CEMS operated 13,676 out of 15,889 hours, equal to 

a reliability of 86 percent. The data show that 1,008 of the 2,213 hours of 

malfunction (45%) were caused by the S02 analyzer. The remaining downtime 

resulted from datalogger malfunction and removal of the inlet sample line 

for repair.

INTRODUCTION: 

The following data of emissions from the Marquette, Michigan 

Board of Light and Power's Shiras Unit No. 3 are reported in 

compliance with Section 114 of the Clean Air Act, as amended, 

42 U.S.C. Section 7414 which requires this data to be submitted quarterly.

UNIT #3 

SUMMARY 

1st Quarter of 1985 

Unit No. 3 was on line for 98 7_ of the 1st quarter, based on 2,160 hours. 

The total number of startup/shutdown's for the quarter was one (1). Unit 

No. 3 had some reportable emissions, equipment malfunctions, instrument 

malfunctions, maintenance periods and calibrations during the quarter. The 

diluent oxygen monitoring system provided 1,512 hours of useful data out of 

a possible 2,160 hours for a data recovery of 70 %. The opacity monitoring 

system provided 2,160 hours of useful data out of a possible 2,160 hours for 

a data recovery of 100 %. 

Opacity limit violations occurred during less than 1 % of the quarter. 

The quarterly average of SO2 at stack discharge was 0.28 lb/MBTU. 

The quarterly average of NO at stack discharge was 0.69 lb/MBTU. 

The Kaye datalogger which serves our gas analyzers for Unit No. 3 had 

data aquisition of 70 % of the quarter. 
P-1? 

Page 2 

Unit #3 

The following pages contain a more specific breakdown of the system availabilities, 

excess emission summary tables, and day-to-day excess emissions and equipment problems. 

The Parameter-Availability - (time periods that yield reasonably reliable data) for 

the Dupont 460/1 (NO /S02 ), Thermox (diluent 0 2 ) , and the RM-41 (opacity) monitoring 

systems include: 

(a) Total - the time that the entire system (instrument, computer, and recorder) was functioning properly. 

(b) Recorder - the time that the instrument and the recorder, but not necessarily the computer, were functioning properly. 

(c) Computer - the time that the instrument and the computer, but not necessarily the recorder, were functioning properly. 

(d) Useful Data - the time that the instrument and at least one of the data 

recording systems were available. 

The Instrument Availability includes the time that the RM-41 was working properly, 

without consideration of the operational status of either the computer or the 

recorder. 

The Dupont 460/1 Estimated values are the "best estimate" calculations performed by 

the computer if the diluent 0~ gas monitor is not working. The program is designed 

to use an artifical 4 % 02 value in the calculation of lb/MBTU (NOX/S02) if the 

oxygen monitor has been taken out of service to the computer. 

The Recorder Availabilities are defined as the hours for which the Kaye Datalogger 

for a particular parameter was operating correctly, irrespective of monitor operation. 

The Boiler Availability includes the time that the unit was on line.

Tlie equations used by the computer, or manually, in the event of a computer failure are: 

(NO ) x (F) x = NO emissions in lb/MBTU (wet basis) 

20.9 (1-B) - 7o 0 2 

20 9 (S02) x (F) x = S02 emissions in lb/MBTU (wet basis) 

20.9 (1-B) - 7» 0 2

(NO ) = average ppm NO x 119.14 x 10 ) 

x x 

(S02) = average ppm S02 x 165.9 x 10 ) 

(B) = moisture in flue gas sample 

(F) = 9044 BTU/lb 

The instruments used in Continuous Emission Monitoring (CEM) will be identified, as 

follows:

OXIDES (Dupont 460/1): REPORTING COMPUTER (Kaye Datalogger) 

All data recorded on Kaye Datalogger 

The equation used to calculate the percent CEM system availability is:

The reportable data for Unit #3 is listed in this report, by day, witb any 

applicable explanations accompanying each day's data. 

Instrument malfunctions which prevented the monitoring of stack emissions 

will be explained on a daily basis. 

Unit or equipment malfunctions which caused excess emissions will also be 

included. 

OPACITY 

For a given date, all opacity violations (6 minute) will be tabulated 

with each violation positioned according to the hour in which it occurred. 

The total hours of excess emissions for the day, the average excess emission 

value and the maximum excess emission value will be given. The percent of 

excess emissions due to startup/shutdown, malfunctions, or normal operation 

will also be given. 

SULFUR DIOXIDE (S02) / NITROGEN OXIDES (NO ) 

For a given date,' all S02 and NO violation time periods (3 - continuous 

hours) will be listed in chronological order, followed by their respective 

violations. The violations will be reported in units of lb/MBTU.

INTRODUCTION: 

The following data of emissions from the Marquette, Michigan 

Board of Light and Power's Shiras Unit No. 3 are reported in 

compliance with Section 114 of the Clean Air Act, as amended, 

42 U.S.C. Section 7414 which requires this data to be submitted quarterly.

UNIT # 3 

SUMMARY 

Second Quarter of 1985 

Unit No. 3 was on line for 100 % on the second quarter, based on 2,184 

hours. 

The total number of startup/shutdowns for the quarter was zero (0). Unit 

No. 3 had some reportable emissions, equipment malfunctions, instrument 

malfunctions, maintenance periods and calibrations during the quarter. 

The diluent oxygen monitoring system provided 2,016 hours of useful data 

out of a possible 2,184 hours for a data recovery of 92.3 %. The opacity 

monitoring system provided 2,160 hours of useful data out of a possible 

2,184 hours for a data recovery of 98.9 %. 

Opacity limit violations occurred during less than 2 % of the quarter. 

The quarterly average of S02 at stack discharge was 0.29 lb/MBTU. 

The quarterly average of NO at stack discharge was 0.68 lb/MBTU. 

The Kaye datalogger, which serves our gas analyzers for Unit No. 3 had 

data aquisition of 91.2 % of quarter.

Unit #3 

The following pages contain a more specific breakdown of the system availabilities, 

excess emission summary tables, and day-to-day excess emissions and equipment problems. 

The Parameter-Availability - (time periods that yield reasonably reliable data) for 

the Dupont 460/1 (NO /S02 ), Thermox (diluent 0 2 ) , and the RM-41 (opacity) monitoring 

systems include: 

(a) Total - the time that the entire system (instrument, computer, and recorder) was functioning properly. 

(b) Recorder - the time that the instrument and the recorder, but not necessarily the computer, were functioning properly. 

(c) Computer - the time that the instrument and the computer, but not necessarily the recorder, were functioning properly. 

(d) Useful Data - the time that the instrument and at least one of the data 

recording systems were available. 

The Instrument Availability includes the time that the RM-41 was working properly, 

without consideration of the operational status of either the computer or the 

recorder. 

The Dupont 460/1 Estimated values are the "best estimate" calculations performed by 

the computer if the diluent 0 2 gas monitor is not working. The program is designed 

to use an artifical 4 % 0 2 value in the calculation of lb/MBTU (NO^SO^ if the 

oxygen monitor has been taken out of service to the computer. 

The Recorder Availabilities are defined as the hours for which the Kaye Datalogger 

for a particular parameter was operating correctly, irrespective of monitor operation . 

The Boiler Availability includes the time that the unit was on line.

The following data of emissions from the Marquette, Michigan 

Board of Light and Power's Shiras Unit No. 3 are reported in 

compliance with Section 114 of the Clean Air Act, as amended,

UNIT # 3 

SUMMARY 

Third Quarter of 1985 

Unit No. 3 was on line for 81.0 % of the 3rd quarter, base on 2.208 

hours. 

The total number of startup/shutdowns for the quarter was one (1) Unit 

No. 3 had some reportable emissions, equipment malfunctions, instrument 

malfunctions, maintenance periods and calibrations during the quarter. 

The diluent oxygen monitoring system provided 2,038 hours of useful data 

out of a possible 2,208 hours for a data recovery of 92.3 %. The opacity 

monitoring system provided 2,184 hours of useful data out of a possible 

2,208 hours for a data recovery of 99.0 %. 

Opacity Limit violations occurred during less than 1 % of the quarter. 

The quarterly average of S02 at stack discharge was 0.29 lb/MBTU. 

The quarterly average of NO at stack discharge was 0.59 lb/MBTU. 

The Kaye datalogger, which, serves our gas analyzers for Unit No. 3 had data 

aquisition of 97 % of quarter. 
P.49 

Page' 2 

Unit #3 

The following pages contain a more specific breakdown of the system availabilities, 

excess emission summary tables, and day-to-day excess emissions and equipment problems, 

The Parameter-Availability - (time periods that yield reasonably reliable data) for 

the Dupont 460/1 (NO /S02 ), Thermox (diluent 0 2 ) , and the RM-41 (opacity) monitoring 

systems include: 

(a) Total - the time that the entire system (instrument, computer, and recorder) was functioning properly. 

(b) Recorder - the time that the instrument and the recorder, but not necessarily the computer, were functioning properly. 

(c) Computer - the time that the instrument and the computer, but not necessarily the recorder, were functioning properly. 

(d) Useful Data - the time that the instrument and at least one of the data 

recording systems were available. 

The Instrument Availability includes the time that the RM-41 was working properly, 

without consideration of the operational status of either the computer or the 

recorder. 

The Dupont 460/1 Estimated values are the "best estimate" calculations performed by 

the computer if the diluent 02 gas monitor is not working. The program is designed 

to use an artifical 4 % 02 value in the calculation of lb/MBTU (NOx/S02) if the 

oxygen monitor has been taken out of service to the computer. 

The Recorder Availabilities are defined as the hours for which the Kaye Datalogger 

for a particular parameter was operating correctly, irrespective of monitor operation. 

The Boiler Availability includes the time that the unit was on line.

UNIT # 3 

SUMMARY 

Fourth Quarter of 1985 

Unit No. 3 was on line for 94.6 % of the 4th quarter, base on 2.208 

hours. 

The total number of star tup/shutdowns for the quarter was one (1) Unit 

No. 3 had some reportable emissions, equipment malfunctions, instrument 

malfunctions, maintenance periods and calibrations during the quarter. 

The diluent oxygen monitoring system provided 2,160 hours of useful data 

out of a possible 2,208 hours for a data recovery of 99 %. The opacity 

monitoring system provided 2,208 hours of useful data out of a possible 

2,208 hours for a data recovery of 100.0 %. 

Opacity limit violations occurred during less than 1 % of the quarter. 

The quarterly average of S02 at stack discharge was 0.27 lb/MBTU. 

The quarterly average of NO at stack discharge was 0.60 lb/MBTU. 

The Kaye datalogger, which, serves our gas analyzers for Unit No. 3 had data 

aquisition of 98 % of quarter. 
Page -2 

Unit #3 

The following pages contain a more specific breakdown of the system availabilities, 

excess emission summary tables, and day-to-day excess emissions and equipment problems. 

The Parameter-Availability - (time periods that yield reasonably reliable data) for 

the Dupont 460/1 (NO /S02), Thermox (diluent 02 ), and the RM-41 (opacity) monitoring 

systems include: 

(a) Total - the time that the entire system (instrument, computer, and recorder) was functioning properly. 

(b) Recorder - the time that the instrument and the recorder, but not.necessarily the computer, were functioning properly. 

(c) Computer - the time that the instrument and the computer, but not necessarily the recorder, were functioning properly. 

(d) Useful Data - the time that the instrument and at least one of the data 

recording systems were available. 

The Instrument Availability includes the time that the RM-41 was working properly, 

without consideration of the operational status of either the computer or the 

recorder. 

The Dupont 460/1 Estimated values are the "best estimate" calculations performed by 

the computer if the diluent 0? gas monitor is not working. The program is designed 

to use an artifical 4 % 02 value in the calculation of lb/MBTU (NOx/S02) if the 

oxygen monitor has been taken out of service to the computer. -

The Recorder Availabilities are defined as the hours for which the Kaye Datalogger 

for a particular parameter was operating correctly, irrespective of monitor operation. 

The Boiler Availability includes the time that the unit was on line.

INTRODUCTION: 

The following data of emissions from the Marquette, 

Michigan Board of Light and Power's Unit No. 3 are 

reported in compliance with Section 114 of the 

Clean Air Act, as amended, 42 U.S.C. Section 7414 

which requires this data to be submitted quarterly. 

The NOx Data in this report is of doubtful accuracy. 

Independent testing in accordance with EPA Method 7 

has shown error in the Continuous Monitor. Mr. 

Dave Shultz, EPA Region 5, is aware of this problem.

UNIT NQ. 3 

SUMMARY 

SECOND QUARTER QF 1986 

Unit No. 3 was on line for 100'/. of the second quarter, 

based on 2, 184 hours. 

The total number of startup/shutdowns for the quarter was 

0. Unit No. 3 had some reportable emissions, equipment 

malfunctions, instrument malfunctions, maintenance periods 

and calibrations during the quarter. The diluent oxygen 

monitoring eystem provided 2,184 hours of useful data out 

of a possible 2, 184 hours for a data recovery of 100%. The 

opacity monitoring system provided 2,184 hours of useful 

data out of a possible 2,184 hours for a data recovery of 

100#/.. 

Opacity limit violations occurred during less than 1'/. of 

the quarter. 

The Quarterly average of SQ2 at stack discharge was 0.325 

lb/MBTU. 

The quarterly average of NOx at stack discharge was 0.476 

lb/MBTU. 

The Kaye datalogger, which services our gas analyzers for 

Unit No. 3 had data acquisition of 99V. of 

quarter. 
P.83 

UNIT NO. 

The following pages contain a more specific breakdown of 

the system availabilities, excess emission summary tables, 

and day-to-day excess emissions and equipment problems. 

The Parameter-Availability - (time periods that yield 

reasonable reliable data) for the Dupont 460/1 (N0x/S02), 

Thermox (diluent 02), and the RM-41 (opacity) monitoring 

systems include: 

(a) Total - the time that the enitre system 

(instrument, computer, and recorder) was function 

properly. 

(b) Recorder - the time that the instrument and the 

recorder, but not necessarily the computer, were 

functioning properly. 

(c) Computer - the time that the instrument and the 

computer, but not necessarily the recorder, were 

functioning properly. 

(d) Useful Data - the time that the instrument and at 

least one of the data recording systems were 

available. 

The Instrument Availability includes the time that the RM41 was working properly, without consideration of the 

operational status of either the computer of the recorder. 

The Dupont 460/1 Estimated values are the "best 

estimate" calculations performed by the computer if the 

diluent 02 gas monitor is not working. The program is 

designed to use an artifical 4% 02 value in the calculation 

of lb/MBTU (NOx S02) if the oxygen monitor has been taken 

out of service to the computer. 

The Recorder1 Avilabilities are defined as the hours for 

which the Kaye Datalogger for a particular parameter was 

operating correctly, irrespective of monitor operation. 

The Boiler Availability includes the time that the unit was 

on line.

UNIT # 3 

SUMMARY 

First Quarter of 1986 

Unit No. 3 was on line for 81.25 7, of the 1st quarter, base on 2,160 

hours. 

The total number of startup/shutdowns for the quarter was 1 (one) . Unit 

No. 3 had some reportable emissions, equipment malfunctions, instrument 

malfunctions, maintenance periods and calibrations during the quarter. 

The diluent oxygen monitoring system provided 1,755 hours of useful data 

out of a possible 1,755 hours for a data recovery of 100 %. The opacity 

monitoring system provided 1,755 hours of useful data out of a possible 

1,755 hours for a data recovery of 100 %. 

Opacity limit violations occurred during less than 1 % of the quarter. 

The quarterly average of S02 at stack discharge was 0»29 lb/MBTU. 

The quarterly average of NO at stack discharge was 0»65 . lb/MBTU. 

J \ ——m_________m______________*•— 

The Kaye datalogger, which, serves our gas analyzers for Unit No. 3 had data 

aquisition of 98 % of quarter.

Unit #3 

Tbe following pases contain a more specific breakdown of tbe system availabilities, 

excess emission summary tables, and day-to-day excess emissions and equipment problems. 

Tbe Parameter-Availability - (time periods that yield reasonably reliable data) for 

tbe Dupont 460/1 (NO /S02), Thermox (diluent 0-), and tbe RM-41 (opacity) monitoring 

systems include: 

(a) Total - the time that tbe entire system (instrument, computer, and recorder) was functioning properly. 

(b) Recorder - tbe time that the instrument and tbe recorder, but not nee-, 

essarily tbe computer, were functioning properly. 

(c) Computer - the time that the instrument and the computer, but not necessarily tbe recorder, were functioning properly. 

(d) Useful Data - the time that the instrument and at least one of the data 

recording systems were available. 

The Instrument Availability includes the time that tbe RM-41 was working properly, 

without consideration of the operational status of either the computer or the 

recorder. 

The Dupont 460/1 Estimated values are tbe "best estimate" calculations performed by 

tbe computer if the diluent 0« gas monitor is not working. The program is designed 

to use an artifical 4 % Or- value in tbe calculation of lb/MBTU (NOx/S02) if tbe 

oxygen monitor bas been taken out of service to the computer. 

The Recorder Availabilities are defined as tbe hours for which the Kaye Datalogger 

for a particular parameter was operating correctly, irrespective of monitor operation. 

The Boiler Availability includes the time that the unit was on line.

INTRODUCTION: 

The following data of emissions from the Marquette, 

Michigan Board of Light and Power's Unit No. 3 are 

reported in compliance with Section 114 of the 

Clean Air Act, as amended, 42 U.S.C. Section 7414 

which requires this data to be submitted quarterly. 

The NOx Data in this report is of doubtful accuracy. 

Independent testing in accordance with EPA Method 7 

hae shown error in the Continuous Monitor. Mr. 

Dave Shultz, EPA Region 5, is aware of this problem.

UNIT NO. 3 

SUMMARY 

THIRD QUARTER QF 1986 

Unit No. 3 was on line for 92. AV. of the third quarter, 

based on 2,208 hours. 

The total number of startup/shutdowns for the quarter was 

1. Unit No. 3 had some reportable emissions, equipment 

malfunctions, instrument malfunctions, maintenance periods 

and calibrations during the quarter. The diluent oxygen 

monitoring system provided 2,040 hours of useful data out 

of a possible 2,040 hours for a data recovery of 100%. The 

opacity monitoring system provided 1,968 hours of useful 

data out of a possible 2,040 hours for a data recovery of 

96.5%. 

Opacity limit violations occurred during less than IV. of 

the quarter. 

The Quarterly average of S02 at stack discharge was 0.307 

lb/MBTU. 

The quarterly average of NOx at stack discharge was 0.360 

lb/MBTU. 

The Kaye datalogger, which services our gas analyzers for 

Unit No. 3 had data acquisition of 92. AV. of 

quarter. 
P.18 

UNIT NO. 

The following pages contain a more specific breakdown of 

the system availabilities, excess emission summary tables, 

and day-to-day excess emissions and equipment problems. 

The Parameter-Availability - (time periods that yield 

reasonable reliable data) for the Dupont 460/1 (N0x/S02), 

Thermox (diluent 02), and the RM-41 (opacity) monitoring 

systems include: 

(a) Total - the time that the entire system 

(instrument, computer, and recorder) was functioning properly. 

(b> Recorder - the time that the instrument and the 

recorder, but not necessarily the computer, were 

functioning properly. 

(c) Computer - the time that the instrument and the 

computer, but not necessarily the recorder, were 

functioning properly. 

(d) Useful Data - the time that the instrument and at 

least one of the data recording systems were 

available. 

The Instrument Availability includes the time that the RM41 was working properly, without consideration of the 

operational status of either the computer of the recorder. 

The Dupont 460/1 Estimated values are the "best 

estimate" calculations performed by the computer if the 

diluent 02 gas monitor is not working. The program is 

designed to use an artifical AV. 02 value in the calculation 

of lb/MBTU (NOx S02) if the oxygen monitor has been taken 

out of service to the computer. 

The Recorder Aviiabilities are defined as the hours for 

which the Kaye Datalogger for a particular parameter was 

operating correctly, irrespective of monitor operation. 

The Boiler Availability includes the time that the unit was 

on line.

INTRODUCTION: 

The following data of emissions from the Marquette, 

Michigan Board of Light and Power's Unit No. 3 are 

reported in compliance with Section 114 of the 

Clean Air Act, as amended, 42 U.S.C. Section 7414 

which requires this data to be submitted quarterly. 
UNIT NQ. 3 

SUMMARY 

Fourth Quarter of 1986 

Unit No. 3 was on line for 83.7% of the fourth quarter, based on 

2, 208 hours. 

The total number of startup/shutdowns for the quarter was 1. 

Unit No. 3 had some reportable emissions, equipment malfunctions, 

instrument malfunctions, maintenance periods and calibrations 

during the quarter. The diluent oxygen monitoring system 

provided 1,848 hours of useful data out of a possible 1,848 hours 

for a data recovery of 100%. The opacity monitoring system 

provided 1,800 hours of useful data out of a possible 1,848 hours 

for a data recovery of 97.4%. 

Opacity limit violations occurred during less than 3% of the 

quarter. 

The quarterly average of S02 at stack discharge was 0.341 

lb/MBTU. 

The quarterly average of NOx at stack discharge was 0.309 

lb/MBTU. 

The Kayedatalogger, which services our gas analyzers for Unit No. 

3 had data acquisition of 92.7% of quarter. 
P.35 

UNIT NQ. 3 

The following pages contain a more specific breakdown of the 

system availabilities, excess emission summary tables, and dayto-day excess emissions and equipment problems. 

The Parameter-Availability - (time periods that yield reasonable 

reliable data) for the DuPont 460/1 (N0x/S02), Thermox (diluent 

02), and the RM-41 (opacity) monitoring systems include: 

a) Total - the time that the entire system 

(instrument, computer, and recorder) was 

functioning properly. 

b) Recorder - the time that the instrument, 

and the recorder, but not necessarily the 

computer were functioning properly. 

c) Computer - the time that the instrument and 

the computer, but not necessarily the recorder, 

were functioning properly. 

d) Useful Data - the time that the instrument 

and at least one of the data recording systems 

were available. 

The Instrument Availability includes the time that the RM-41 was 

working properly, without consideration of the operational status 

of either the computer or the recorder. 

The Dupont 460/1 Estimated values are the "best estimate" 

calculations performed by the computer if the diluent 02 gas 

monitor is not working. The program is designed to use an 

artifical 4% 02 value in the calculation of lb/MBTU (NOx S02) if 

the oxygen monitor has been taken out of service to the computer. 

The Recorder Availabilities are defined as the hours for which 

the Kayedatalogger for a particular parameter was operating 

correctly, irrespective of monitor operation. 

The Boiler Availability includes the time that the unit was on 

line.
