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

HP Located at Major Sources

1.0 PURPOSE 

The purpose of this memorandum is to present the maximum achievable control 

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

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

located at major sources. These engines are subject 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 stationary SI engines that are less 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 greater 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 sources and existing stationary SI engines that are less than or equal 

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

engines. 

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

Clean Air Act (CAA). The MACT floor for existing 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 information. 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.

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 (2SLB) stationary SI RICE 100-500 HP; 

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

 Non-emergency 4-stroke rich burn (4SRB) 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-stroke versus 4-stroke) in a previous memorandum.1 

The rationale provided in that memorandum supports establishing the subcategories listed above, 

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

comments received on the proposed rule 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 performing 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 available at the time. Following the proposed rule, 

EPA received additional emissions test data for more than 600 engines. EPA received emissions 

data for 2SLB, 4SLB, and 4SRB engines, and engines 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 appropriateness 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 all other stationary SI 

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

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

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 determine the emission limits for the final rule, 

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

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

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

in our data set. Specifically, the MACT floor limit is an upper prediction 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%) + [STDEV (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/Infectious Waste Incinerators, Proposed NESHAP 

for Industrial, Commercial, and Institutional Boilers 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, the prediction interval estimates what future 

values will be, based upon present or past background 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 randomly 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 calculate the UPL, EPA used the average (or sample 

mean) and sample standard deviation, which are 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 set 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 analysis, are reasonably designed to 

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

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

determination for each subcategory is described below 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 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 CO emissions data for 28 stationary 

2SLB engines below 500 HP. Therefore, the top 12 percent is represented by 3 engines. EPA 

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

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

performing engines, which accounts for variability. 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 average of the best performing sources if the best performing 

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

rounding up to the nearest whole integer, the MACT floor for 2SLB 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 (O2). A summary of the test data that 

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

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

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

evaluated the cost of oxidation catalyst control compared to the 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 capital investment and total annual control 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 reduced, 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 than 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 O2. 

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 would be appropriate. 

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

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

500 HP. Information gathered during the development of the New Source Performance 

Standards for Stationary SI Engines4 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 approach previously discussed, the MACT floor for 

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

sources is 47 ppmvd of CO at 15 percent O2. A summary of the test data that was used to set the 

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

The MACT floor for existing non-emergency 4SLB 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 oxidation catalyst. EPA found no evidence in the 

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

engines, in particular no other emissions controls that reduce HAP by a greater amount than 

oxidation catalyst. Additional above-the-floor emissions 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 O2. 

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 formaldehyde emissions data for 51 

4SRB engines less than 500 HP, which resulted in 6 engines representing 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 approach previously discussed, the MACT floor for 

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

sources is 10.3 ppmvd of formaldehyde at 15 percent O2. 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-floor and considered non-selective catalytic 

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

oxides (NOx) reductions from existing stationary 4SRB engines. EPA evaluated the cost of 

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

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

less than or equal to 500 HP at major sources would require significant total 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 engines, 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 per ton of HAP removed for going beyond-the-floor 

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

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

floor for existing stationary non-emergency 4SRB engines 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 O2. 
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 combust these fuels. Therefore, EPA found that 

using all available test data would 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 approach described earlier in this memorandum and 

rounding up to the nearest whole integer, the MACT 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 O2. 

 Oxidation catalyst and NSCR were considered 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 controls to engines combusting waste gas, which 

include fouling of the catalyst by siloxanes resulting in an inoperable 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 the MACT floor and is 177 ppmvd of CO at 15 percent O2. A summary 

of the test data that was used to set the MACT floor is presented in Appendix D-1 and D-2.
