MEMORANDUM

DATE: August 10, 2010

SUBJECT: Emission Factors for Existing Stationary SI RICE

FROM: Bradley Nelson, EC/R, Inc.

TO: Melanie King, EPA OAQPS/SPPD/ESG

1.0 PURPOSE

The purpose of this memorandum is to present the hazardous air pollutants (HAP), 

volatile organic compounds (VOC), carbon monoxide (CO) and nitrogen oxides (NOx) emission 

factors that were used for existing stationary spark ignition (SI) reciprocating internal 

combustion engines (RICE) in order to estimate impacts under the national emission standards 

for hazardous air pollutants (NESHAP) that these engines are subject to.

2.0 INTRODUCTION

EPA used information presented in the Compilation of Air Pollutant Emission Factors (AP-42) 

to estimate HAP emission factors for 2-stroke lean burn (2SLB), 4-stroke lean burn (4SLB), and 

4-stroke rich burn (4SRB) engines for the final NESHAP. The trace organic compounds that 

were defined by section 112(b) of the Clean Air Act as HAP were summed for each engine type 

(i.e., 2SLB, 4SLB, 4SRB). Based on comments received during public comment interagency 

review period, EPA determined that the AP-42 emission factors for HAP would be the most 

appropriate and representative to estimate HAP emissions from existing SI engines.

For CO and NOx, EPA developed emission factors for existing stationary SI engines using test 

data from the RICE Emissions Database and supplemented this data, to the extent all information 

was available, with emissions data received after the proposal. The following sections describe 

how EPA estimated HAP emission factors from AP-42 information and CO and NOx emission 

factors from available emissions data.

3.0 METHODOLOGY FOR DEVELOPING EMISSION FACTORS

The following section describes the methodology used to develop emission factors for 

existing SI engines. These methodologies were developed by EPA and used to calculate AP-42 

emission factors.1 These methodologies include:

 Data Collection and Review,

 Data Evaluation and Analysis,

 Emission Data Grouping,

 Development of Emission Factors.

The data collection and review process included the collection of test reports that were submitted 

during the comment period. The pollutant test data from the new test reports were added to the 

existing dataset to create a revised pollutant data set. The data evaluation step included the 

review of the new test reports to verify that the data was of proper quality and included the 

necessary quality assurance and quality control data (QA/QC). The emission data grouping step 

included separating the data by engine type (2SLB, 4SLB, 4SRB) and pollutant. The data sets 

were further grouped by facility and by engine model. The development of emission factors step 

involved averaging the pollutant test runs for each engine model located at a facility. The 

average emission factors from each engine model at a facility were then averaged to calculate the 

pollutant emission factor for that engine type. Section 4.0 presents a summary of the results of 

the emission factor development for each of the engine types.

4.0 EMISSION FACTORS

The HAP emission factors for each of the engine types were calculated using the Trace 

Organic Compound emission factors presented in the Compilation of Air Pollutant Emission 

Factors (AP-42).2 The trace organic compounds that were defined by section 112(b) of the Clean 

Air Act as HAP were summed for each engine type (i.e., 2SLB, 4SLB, 4SRB). The resulting 

engine type AP-42 HAP emission factor was then converted from pounds per million British 

Thermal Units (lb/MMBtu) to pounds per horsepower-hour (lb/HP-hr) using the following 

equation:3 

lb/HP-hr = lb/MMBtu * 0.002546 MMBtu/HP-hr/0.34

where 0.34 is the assumed efficiency for a SI engine.

HAP Emission Factors for Small (≤500 HP) Stationary Reciprocating Internal Combustion Engines (RICE), April 

13, 2004 (EPA-HQ-OAR-2005-0030-0009).

The VOC emission factor was calculated by dividing the HAP emission factor in lb/HPhr for each engine type by 0.194, which was the HAP/VOC ratio that was established and used to 

estimate impacts under the New Source Performance Standards for SI engines and NESHAP for 

stationary RICE promulgated in 2008.

4

The CO and NOx test data from the RICE Emissions Database were used to calculate CO 

and NOx emission factors for each engine type. In addition, CO test data received during the 

comment period was included in the emission data set for 4SLB and 4SRB engines. The CO and 

NOx emission factors were calculated first by averaging the test data from each engine model at a 

facility for each engine type. The averages of each of these engine models were then averaged to 

calculate a CO and NOx emission factor for the engine type. A summary of the test data and 

calculations for the CO and NOX emission factors are presented in Appendix A of this 

memorandum.
