SUBJECT: MACT Floor and MACT Determin ation for Existing Stationary SI RICE ≤ 500

HP Located at Major Sources

FROM: Tanya Parise, EC/R, Inc.

TO: Melanie King, EPA OAQPS/SPPD/ESG

1.0 PURPOSE

The purpose of this memorandum is to pr esent the maximum achievable control

technology (MACT) floor and MACT determinati on for existing stationary spark ignition (SI)

reciprocating internal combusti on engines (RICE) less than or equal to 500 horsepower (HP)

located at major sources. These engines are subj ect to national emission standards for hazardous

air pollutants (NESHAP) under 40 CFR part 63, subpart ZZZZ.

2.0 INTRODUCTION

EPA proposed NESHAP for existing stationary SI engines at area sources of hazardous

air pollutants (HAP) and existing st ationary SI engines that are le ss than or equal to 500 HP at

major sources of HAP on March 5, 2009 (71 FR 9698). The EPA previously promulgated

NESHAP for existing stationary SI engines gr eater than 500 HP that are located at major

sources, which were published on June 14, 2004 ( 69 FR 33474). The final NESHAP for existing

stationary SI engines at area sour ces and existing stationary SI engi nes that are less than or equal

to 500 HP at major sources will add requireme nts to 40 CFR part 63, subpart ZZZZ, for these

engines.

The final NESHAP was developed following cr iteria set forth under section 112 of the

Clean Air Act (CAA). The MACT floor for existi ng sources must be no less stringent than the

average emission limitation achieved by the best performing 12 percent of existing sources for

which the Administrator has emissions inform ation. The MACT standards must be no less

stringent than the MACT floor. EPA must also determine whether to control emissions “beyondthe-floor,” after considering the costs, non-air quality health and environmental impacts, and

energy requirements of such more stringent control.

# 2 Section 112 of the CAA allows the EPA to establish subcategories among a group of

sources. In order to properly take into account the differences between existing stationary SI

engines less than or equal to 500 HP at major sources, EPA has determined that the following

subcategories are appropriate:

 Non-emergency 2-stroke lean burn (2 SLB) stationary SI RICE 100-500 HP;

 Non-emergency 4-stroke lean burn (4 SLB) stationary SI RICE 100-500 HP;

 Non-emergency 4-stroke rich burn (4 SRB) stationary SI RICE 100-500 HP;

 Non-emergency landfill and digester gas stationary SI RICE 100-500 HP;

 Non-emergency stationary SI RICE <100 HP; and

 Emergency stationary SI RICE.

EPA has discussed the appropriateness of distinguishing stationary engines by

capacity/size, fuel, mode of operation (emergency versus non-emergency), burn type (lean burn

versus rich burn), and number of strokes (2-s troke versus 4-stroke) in a previous memorandum. 1



# The rationale provided in that memorandum suppor ts establishing the sub categories listed above,

with the exception that for small existing stati onary SI engines, EPA has determined based on

comments received on the proposed ru le that it is appropriate to define small engines as those

below 100 HP.

3.0 MACT FLOOR AND MACT DETERMINATION

General Approach

The MACT floor for existing stationary RICE must be no less stringent than the average

emission limitation achieved by the best performi ng 12 percent of existing sources for which the

Administrator has emissions information. In the proposed rule, EPA established the MACT

floor using the emissions data that EPA had ava ilable at the time. Following the proposed rule,

EPA received additional emissions te st data for more than 600 engines. EPA received emissions

data for 2SLB, 4SLB, and 4SRB engines, and en gines using landfill and digester gas. The

emissions test data included test results from engines ranging in size from 39 HP to 12,000 HP at

loads between 11 and 100 percent. The additional test data EPA received is available from the

docket (EPA-HQ-OAR-2008-0708).

EPA believes that previous determinations regarding the appr opriateness of using

formaldehyde levels in concentration (parts per million (ppm)) as surrogates for HAP for 4SRB

stationary SI RICE, and carbon monoxide (CO) levels in concentration for al l other stationary SI

RICE, are still valid. Consequently, EPA is fi nalizing formaldehyde standards for 4SRB RICE

and CO standards for other SI RICE to regulate HAP emissions.

# 3 MACT Floor Approach

In order to determine the MACT floor for each subcategory, EPA ranked all of the

sources for which it had data based on their emissions and identified the lowest emitting 12

percent of the sources based on the lowest test for each engine. EPA used all of the emissions

data for those best performing engines to de termine the emission limits for the final rule,

accounting for variability. EPA assessed the vari ability of the best performers by using a

statistical formula designed to estimate a MACT fl oor level that is achieved by the average of the

best performing sources if the best performing sour ces were able to replicate the compliance tests

in our data set. Specifically, the MACT floor limit is an upper predic tion limit (UPL) calculated

with the Student’s t-test using the TINV function in Microsoft Excel, assuming normal

distribution as shown below:

UPL = AVERAGE (Test Runs in Top 12%) + [S TDEV (Test Runs in Top 12%) x TINV (2 x

0.01, n-1 degrees of freedom) x SQRT ((1/n)+(1/3))]

The Student’s t-test has also been used in other EPA rulemakings (e.g., New Source

Performance Standards for Hospital/Medical/Inf ectious Waste Incinerators, Proposed NESHAP

for Industrial, Commercial, and Institutional Bo ilers and Process Heaters) in accounting for

variability. A prediction interval for a future observation is an interval that will, with a specified

degree of confidence, contain the next (or some other pre- specified) randomly selected

observation from a population. In other words, th e prediction interval estimates what future

values will be, based upon present or past back ground samples taken. Given this definition, the

UPL represents the value which EPA can expect the mean of 3 future observations (3-run

average) to fall below, based upon the results of an independent sample from the same

population. In other words, if EPA was to randoml y select a future test condition from any of

these sources (i.e., average of 3 runs), EPA can be 99 percent confident that the reported level

will fall at or below the UPL value. To calcula te the UPL, EPA used the average (or sample

mean) and sample standard deviation, which ar e two statistical measures calculated from the

sample data. The average is the central value of a data set, and the standard deviation is the

common measure of the dispersion of the data se t around the average. This approach reasonably

ensures that the emission limit selected as the MACT floor adequately represents the level of

emissions actually achieved by the average of the units in the top 12 percent, considering

ordinary operational variability of those units. Both the analysis of the measured emissions from

units representative of the top 12 percent, and the variability an alysis, are reasonably designed to

provide a meaningful estimate of the average pe rformance, or central tendency, of the best

controlled 12 percent of un its in a given subcategory. The MACT floor and MACT

determination for each subcategory is described be low and is summarized in Table 1. Note that

the determination for emergency SI RICE and non- emergency stationary SI RICE less than 100

HP are discussed in separate memorandum. 2

# Non-Emergency 2SLB 100 ≤ HP ≤ 500

For 2SLB engines between greater than or e qual to 100 HP and less th an or equal to 500

HP, EPA found that using test da ta from engines less than 500 HP would be appropriate and

most representative of engines in this subcategory. EPA has CO emissions data for 28 stationary

2SLB engines below 500 HP. Therefore, the t op 12 percent is represen ted by 3 engines. EPA

ranked the data and identified the lowest emitti ng 12 percent based on the lowest test for each

engine. In order to determine the MACT floor, EP A used all of the emissions data for the 3 best

performing engines, which accounts for variabilit y. As discussed, EPA assessed the variability

of the best performers by using a statistical formula (UPL) designed to estimate a MACT floor

level that is achieved by the av erage of the best performing s ources if the best performing

sources were able to replicate the compliance test s in EPA’s dataset. Based on this approach and

rounding up to the nearest whole in teger, the MACT floor for 2S LB engines greater than or

equal to 100 HP and less than or equal to 500 HP located at major sources is 225 ppm by

volume, dry basis (ppmvd) of CO at 15 percent oxygen (O 2 

# ). A summary of the test data that

was used to set the MACT floor is presented in Appendix A-1 and A-2.

# 5 EPA evaluated whether to go beyond-the-floor and considered oxidation catalyst. The

technology is capable of reducing HAP and CO fr om existing stationary 2SLB engines. EPA

evaluated the cost of oxidation ca talyst control compared to th e HAP reductions that would be

achieved. Going above-the-floor and requiring oxidation catalyst on all non-emergency 2SLB

engines greater than or equal to 100 HP and less than or equal to 500 HP at major sources would

require significant total capita l investment and total annual co ntrol costs, which EPA does not

believe are justified for these engines. Also, the cost per ton of HAP reduced for a 250 HP nonemergency 2SLB engine is $186,000 and $109,000 for a 500 HP engine, which EPA believes are

unreasonable. The cost per ton is based on reducing HAP emissions by 43 percent from

uncontrolled levels, which was the average HAP reduction observed during EPA’s testing at

Colorado State University (CSU). 3 

# The 43 percent equates to a HAP emission reduction of 108

pounds per year (lb/yr) for a 250 HP engine or 360 lb/yr for a 500 HP engine. For further

information on the cost per ton of HAP reduce d, please refer to the memorandum entitled “Cost

per Ton of HAP Reduced for Existing Stationary SI RICE” in the rulemaking docket (EPA-HQOAR-2008-0708). EPA does not believe the costs justify going above-the-floor for existing

stationary non-emergency 2SLB engines greater th an or equal to 100 HP and less than or equal

to 500 HP. Therefore, MACT is equivalent to the MACT floor for this subcategory and is 225

ppmvd of CO at 15 percent O 2



# .

Non-Emergency 4SLB 100 ≤ HP ≤ 500

For 4SLB engines greater than or equal to 100 HP and less than or equal to 500 HP, EPA

found that using test data from engines less than or equal to 1,000 HP woul d be appropriate.

EPA does not have any data for 4SLB engines be low 500 HP and believes that test data from

engines less than or equal to 1,000 HP would be re presentative of engines less than or equal to

500 HP. Information gathered during the de velopment of the New Source Performance

Standards for Stationary SI Engines 4 

# showed that emissions from 4SLB engines between 500

and 1000 HP were similar to emissions from 4SLB engines less than 500 HP. EPA has CO

emissions data for 33 stationary 4SLB engines less than or equal 1,000 HP. EPA ranked the data

and identified the lowest emitting 12 percent based on the lowest test for each engine. For 4SLB

engines greater than or equal to 100 HP and less than or equal to 500 HP, the top 12 percent is

represented by 4 engines. Based on the appro ach previously discusse d, the MACT floor for

4SLB engines greater than or e qual to 100 HP and less than or e qual to 500 HP located at major

sources is 47 ppmvd of CO at 15 percent O 2 

# . A summary of the test data that was used to set the

MACT floor is presented in Appendix B-1 and B-2.

# See document number EPA-HQ-OAR-2005-0030-0053 in the docket for the New Source Performance Standards

for Stationary SI Engines.

# 6 The MACT floor for existing non-emergency 4S LB engines greater than or equal to 100

HP and less than or equal to 500 HP is based on the emissions data from the best performing 4

engines. These 4 engines are equipped with oxi dation catalyst. EPA found no evidence in the

record of other available emission controls fo r reducing HAP emissions from stationary 4SLB

engines, in particular no othe r emissions controls that redu ce HAP by a greater amount than

oxidation catalyst. Additional above-the-floor em issions reductions may not be achieved by all

engines. Therefore, MACT is equivalent to the MACT floor for this subcategory and is 47

ppmvd of CO at 15 percent O 2



# .

Non-Emergency 4SRB 100 ≤ HP ≤ 500

For 4SRB engines greater than or equal to 100 HP and less than or equal to 500 HP, EPA

found that using test data from engines less than 500 HP would be appropriate and most

representative of engines in this subcategory. EPA has form aldehyde emissions data for 51

4SRB engines less than 500 HP, whic h resulted in 6 engines repr esenting the best performing

engines. Again, EPA ranked the data and identified the lowest emitting 12 percent based on the

lowest test for each engine. Based on the appr oach previously discussed, the MACT floor for

4SRB engines greater than or equa l to 100 HP and less than or equal to 500 HP located at major

sources is 10.3 ppmvd of formaldehyde at 15 percent O 2 

# . A summary of the test data that was

used to set the MACT floor is presented in Appendix C-1 and C-2.

EPA evaluated whether to go beyond-the-floo r and considered non- selective catalytic

reduction (NSCR). The technology is capable of HAP and CO reductions, as well as nitrogen

oxides (NO

x 

# ) reductions from existing st ationary 4SRB engines. EP A evaluated the cost of

NSCR control compared to the HAP reductions th at would be achieved. Going above-the-floor

and requiring NSCR on all non-emergency 4SRB e ngines greater than or equal to 100 HP and

less than or equal to 500 HP at major sources would require significant to tal capital investment

and total annual control costs, which EPA does not believe are justified for these engines. For

example, capital control costs are estimated at $179 million for non-emergency 4SRB engines

between 100 HP and 500 HP. For the same engine s, annual control costs alone are estimated to

be $67 million. EPA believes these costs are not reasonable given the amount of emission

reductions that would be achieved. The cost pe r ton of HAP removed for going beyond-the-floor

and requiring emission limits based on the use of NSCR for non-em ergency 4SRB engines

would be $141,000 per ton of HAP removed. Theref ore, MACT is equivalent to the MACT

floor for existing stationary non-emergency 4SRB e ngines greater than or equal to 100 HP and

less than or equal to 500 HP and is 10.3 ppmvd of formaldehyde at 15 percent O 2



# .

# 7 Non-Emergency Landfill/Digester Gas 100 ≤ HP ≤ 500

For stationary engines operating on landfill and digester gas fuels, EPA did not have any

emissions data for engines below 500 HP that co mbust these fuels. Therefore, EPA found that

using all available test data w ould be appropriate and believes that using data for larger size

engines would be representative of engines in this subcategory. EPA has CO emissions data for

176 engines combusting either landfill or digester gas fuels. Again following the same approach

as discussed, EPA ranked the data and identified the lowest emitting 12 percent based on the

lowest test for each engine, which for this subcategory resulted in 21 engines representing the

best performing engines. Following the appro ach described earlier in this memorandum and

rounding up to the nearest whole integer, the MA CT floor for landfill and digester gas engines

greater than or equal to 100 HP and less than or equal to 500 HP located at major sources is 177

ppmvd of CO at 15 percent O 2



# .

Oxidation catalyst and NSCR were consider ed as above-the-floor regulatory options for

stationary engines operating on landfill and digester gas fuels. However, because of technical

difficulties in successfully applying such contro ls to engines combusting waste gas, which

include fouling of the catalyst by s iloxanes resulting in an inoperab le catalyst in short periods of

time, EPA determined that there are no viable above-the-floor options. Therefore, due to

feasible technology not being available at this time, MACT for existing stationary landfill and

digester gas engines greater than or equal to 100 HP and less than or equal to 500 HP at major

sources is equivalent to th e MACT floor and is 177 ppmvd of CO at 15 percent O 2
