2.4.1 Utah Administrative Code Rule R307-510-4 Standards

In accordance with the Utah Administrative Code Rule R307-510-4 from the Oil and Gas
Industry: Natural Gas Engine Requirements (510), testing will be conducted to show levels in
units of HC+NOx and CO (as g/BHp-hr).
2.4.2 EPA 40 CFR 60, Subpart JJJJ Standards

According to the requirements of EPA 40, CFR 60 Subpart JJJJ § 60.4233(d), non-emergency
stationary SI ICE manufactured after July 1st, 2008, and rated between 25 hp and 100 hp must
comply with the requirements of the standards for field testing listed in 40 CFR § 1048.101(c).
Under 40 CFR § 1048.101(c)(2) the HC + NOx standard is 3.8 g/KW-hr (2.8 g/BHp-hr) and the
CO standard is 6.5 g/kW-hr (4.8 g/BHp-hr). For natural gas-fueled engines, owners and operators
are not required to measure non-methane hydrocarbon emissions or total hydrocarbon emissions
to show that the engines meet the emission standards; that is, HC is assumed to equal zero.

Emission Measurement Methodologies:

The units will be tested according to EPA 40 CFR 60 (A), Methods 1, 3A, 4, 7E, 10, 18, 19 and
25A. Method 18 grab bags will be utilized to account for Methane and Ethane contents for the
determination of NMNEHC. Emissions in terms of g/BHp-hr will be converted from ppm levels
using the formulae from the Wyoming/Colorado portable analyzer protocol and a BSFC factor
(BTU/BHp-hr). Three, one hour tests will be conducted on each engine.

Operating Parameters:

Operating parameters, where applicable, will be recorded for each 1 hour test which may include
engine rpm, air/fuel ratio setting(s), suction/discharge pressures, ect.

Engine Load Approximation:

Oasis Emission Consultants, Inc. will approximate the engine load using the measured process
parameters, such as gas throughput, suction/discharge pressure/temperature; by correlating the
intake manifold conditions with the engine manufacture heat balance data; or, the engine load.
Maximum Engine hp HC+NOX CO
Equal to or greater than 25 hp
and < 100 hp
2.83 g/BHp-hr 4.85 g/BHp-hr
Maximum Engine Power NOX CO
Greater than 19 KW (25 hp)
and less than 75 KW (100)
(except gasoline and rich burn
engines that use LPG)
2.8 g/BHp-hr
(3.8 g/kW-hr)
4.8 g/BHp-hr
(6.5 g/kW-hr)
It is expected that the performance tests will be conducted within ±10% of 100% peak, or the
highest achievable load.

Test Methods:

All EPA test methods that we intend to utilize are listed below.

 EPA 40 CFR 60 Appendix A, Method 1: Method 1 requires measurement of the various
physical attributes of a stack to establish appropriate sampling locations. An O2 stratification
check will be performed according to 8.1.2 of Method 7E prior to testing to determine
sampling location for engines with stack diameters greater than 6 inches, but less than 12
inches. For stacks equal to or greater than 12 inches in diameter, if the sampling port
locations meet the minimum Method 1 criterion for distance from disturbances, sampling
may be conducted at three points. If sampling ports do not meet Method 1 criterion for
distance from disturbances, stacks equal to or greater than 12 inches in diameter will have an
O2 stratification check performed to determine sampling locations. An O2 stratification is not
required for engines with a stack diameter less than 4 inches.
 EPA 40 CFR 60 Appendix A, Method 3A: O2 measurements will be conducted using an
instrumental analyzer according to Method 3A. The O2 levels will be used in conjunction
with Method 19 to determine the overall exhaust effluent flow.
 EPA 40 CFR 60 Appendix A, Method 4: Method 4 allows for the evaluation of the
moisture content within the effluent stream. A sample of the effluent stream is extracted at a
constant rate. The water is condensed from the stream through a series of impingers
surrounded by an ice bath. The total mass of the water condensed and the total volume of gas
measured are used to calculate the moisture content within the exhaust effluent stream.
 EPA 40 CFR 60 Appendix A, Method 7E: Method 7E is the instrumental method for
measuring the NOx concentration in the effluent stream. After passing through a sample
conditioning system, NOx concentration is measured by a chemiluminescent gas analyzer.
The analyzer is calibrated using EPA Protocol G1 gas before and after each one hour test
run.
 EPA 40 CFR 60 Appendix A, Method 10: Method 10 is the instrumental method for
measuring the CO concentration in the effluent stream. After passing through a sample
conditioning system, CO concentration is measured by a NDIR gas analyzer. The analyzer is
calibrated using EPA Protocol G1 gas before and after each one hour test run.
 EPA 40 CFR 60 Appendix A, Method 18: Method 18 employs an integrated grab bag
sampling system. Method 18 will be utilized to account for Ethane and Methane
concentrations to determine NMNEHC.
 EPA 40 CFR 60 Appendix A, Method 19: The BSFC factor and the measured Oxygen
content will be used to arrive at the overall exhaust effluent flow.
 EPA 40 CFR 60 Appendix A, Method 25A: Total Hydrocarbons will be measured on a hot-
wet basis by using a Flame Ionization Analyzer. This analyzer will be calibrated using EPA
Protocol G1 Propane (C3) gas before and after each one hour test run.
