Re: Kinder Morgan Altamont LLC – Altamont Main Gas Processing Plant
Approval Order DAQE-AN100050016-20 &
Title V Operating Permit # 1300006003
R307-401-12 Notification for Replacement of Compressor Engine

Dear Mr. Burge:

Kinder Morgan Altamont LLC (Kinder Morgan) operates the Altamont Main Gas Processing Plant, which is
currently permitted to operate under Approval Order DAQE-AN100050016-20 (dated April 13, 2020) and
Title V Operating Permit (#1300006003 (dated September 27, 2022). Kinder Morgan is proposing to
replace one existing compressor engine identified as ICE-9 at the station with a like-kind unit, which will
have additional emission controls. The replacement four-stroke rich-burn (4SRB) engine will have a
maximum site and nameplate rating of 1,030 bhp, which is consistent with the rating of the existing
engine. In addition, the engine will be configured with non-selective catalytic reduction catalyst (NSCR)
and an air-fuel-ratio controller (AFRC). Kinder Morgan plans to operate the existing ICE-9 engine until the
replacement unit is installed. At no time will the replacement engine and the engine it replaces both
operate simultaneously. The compressor will not be replaced as part of the project.

This replacement will not increase the potential to emit (PTE) of any air pollutant nor cause emissions of
any new air pollutant. Utah Rule R307-401-12 provides an exemption from the requirement to submit a
Notice of Intent (NOI) as follows:

R307-401-12. Reduction in Air Contaminants.

(1) Applicability. The owner or operator of a stationary source of air contaminants that reduces or
eliminates air contaminants is exempt from the requirement to submit a notice of intent and obtain
an approval order prior to construction if:

(a) the project does not increase the potential to emit of any air contaminant or cause
emissions of any new air contaminant, and

(b) the director is notified of the change and the reduction of air contaminants is made
enforceable through an approval order in accordance with (2) below.

(2) Notification. The owner or operator shall submit a written description of the project to the
director no later than 60 days after the changes are made. The director will update the source's
approval order or issue a new approval order to include the project and to make the emission
reductions enforceable. Public review under R307-401-7 is not required for the update to the
approval order.

This project meets the Reduction in Air Contaminants exemption because:

(a) The project does not increase the PTE of any air contaminant or cause emissions of any new air
contaminant, and
(b) With this letter, notification of the change is being provided in accordance with paragraph (b).
The project is expected to commence on September 16, 2024.

The project triggers applicability to 40 CFR 60 Subpart JJJJ for “new” (as defined in the rule) non-
emergency 4SRB engines ≥500 hp. The replacement engine will be subject to emissions limits for nitrogen
oxides (NOx) (1.0 g/HP-hr), carbon monoxide (CO) (2.0 g/HP-hr), and volatile organic compounds (VOC)
(0.7 g/HP-hr) from Table 1 in 40 CFR 60.4233(c) for engines manufactured after January 1, 2011. The
replacement engine will be considered a “non-certified” engine for purposes of this rule. Per 40 CFR
60.4243(a)(2)(iii), Kinder Morgan will be required to complete performance testing initially (within 180
days of initial startup) and every 8,760 hours or 3 years thereafter, whichever comes first. 60.4243(a)(2)(iii)
also requires Kinder Morgan to keep a maintenance plan and records of conducted maintenance and will
be required to, to the extent practicable, maintain and operate the engine in a manner consistent with
good air pollution control practice for minimizing emissions. Per 40 CFR 60.4243(g), for each engine
configured with an AFRC, the controller must be maintained and operated appropriately in order to
ensure proper operation of the engine and control device to minimize emissions at all times.

The project does not include any modifications or changes to the compressor. Therefore, the project does
not trigger applicability to 40 CFR 60 Subpart OOOOb at 60.5385b (reciprocating compressor
requirements) for CE-2, nor does it trigger requirements of 60.5397b for fugitive emissions.

For purposes of 40 CFR 63 Subpart ZZZZ, per 40 CFR 63.6590(c)(1), a “new” (as defined in the rule)
stationary reciprocating internal combustion engine (RICE) located at an area source of HAP is required to
meet the requirements of 40 CFR 60 Subpart JJJJ for a spark ignition engine. The replacement engine
meets these criteria; no further requirements under 40 CFR 63 Subpart ZZZZ will apply for this engine.

The project also triggers applicability to Utah Rule R307-501 which applies to all oil and natural gas
exploration, production, and transmission operations, well production facilities, natural gas compressor
stations, and natural gas processing plants in Utah. The facility meets these criteria, and the project is
subject to R307-501. The project is not subject to other requirements within R307-502 through R307-511
generally because the replacement equipment will be regulated by an Approval Order, is not located at a
well site, and the compressor is not impacted by the project.

Under the provisions of R307-401-12, a BACT evaluation is not formally required. Note that a previous
BACT determination that Kinder Morgan performed for installation of a similar engine at another Utah
facility concluded that new compressor engines equipped with NSCR catalyst for NOx, CO, and VOC
control would be lower than the generally-accepted BACT. No add-on controls are expected to be feasible
for sulfide dioxide (SO2) and particulate matter (PM10 and PM2.5) from internal combustion engines firing
pipeline quality natural gas.

The estimated change in potential emissions from the engine is summarized in the table below. The “Pre-
Project PTE” includes total potential emissions from the existing engine that is being replaced (the engine
within CE-2, excluding compressor) and “Post-Project PTE” includes total potential emissions from the
replacement engine (excluding compressor). Detailed emission calculations are provided in Attachment A,
and the engine specifications are attached as Attachment B to this notification.

Table 1. Estimated Change in Potential Emissions (tpy)
Contaminant Pre-Project PTE Post-Project PTE Difference
NOx 6.96 6.96 0.00
CO 4.97 4.97 0.00
VOC 0.70 0.70 0.00
SO2 0.02 0.02 0.00
PM / PM10 / PM2.5 0.65 0.65 0.00
Total 13.30 13.30 0.00

Kinder Morgan requests concurrence from the Utah Division of Air Quality (UDAQ) that this project meets
the R307-401-12 Reduction in Air Contaminants exemption.

Furthermore, as a follow-up action to make this project enforceable, Kinder Morgan requests UDAQ issues
an update to the facility’s Approval Order. Kinder Morgan is requesting addition of the following permit
changes within the AO:

1. Change the applicability for unit ICE-9 to include JJJJ.

Kinder Morgan also requests that the facility’s Title V Operating Permit (#1300006003 (dated September
27, 2022) incorporate these changes.

Please do not hesitate to contact me at 303-914-7605 or [e-mail] if you have
questions as you process this request.

Sincerely,

Erin Dunman
EHS Engineer

Standard Conditions per ASTM D3588-91 [60°F and 14.696psia] and
ISO 6976:1996-02-01[25, V(0;101.325)].
Based on the fuel composition, supply pressure and temperature, liquid
hydrocarbons may be present in the fuel. No liquid hydrocarbons are
allowed in the fuel. The fuel must not contain any liquid water.
Waukesha recommends both of the following:
1) Dew point of the fuel gas to be at least 20°F (11°C) below the
measured temperature of the gas at the inlet of the engine fuel
regulator.
2) A fuel filter separator to be used on all fuels except commercial
quality natural gas.
Refer to the 'Fuel and Lubrication' section of 'Technical Data' or contact
the Waukesha Application Engineering Department for additional
information on fuels, or LHV and WKI* calculations.

NOTES
SPECIAL REQUIREMENTS
Requires option code 1008B/1008SB for 0.15 g/bhp-hr NOx 0.30 g/bhp-hr CO catalyst.
20. In cold ambient temperatures, heating of the engine jacket water, lube oil and combustion air may be required. See Waukesha Technical Data.
18. Continuous Power Rating: The highest load and speed that can be applied 24 hours per day, seven days per week, 365 days per year except for normal
maintenance at indicated ambient reference conditions and fuel. It is permissible to operate the engine at the indicated overload power, for two hours in every
24 hour period.
19. emPact emission compliance available for entire range of operable fuels; however, fuel system and/or O2 set point may need to be adjusted in order to
maintain compliance.
12. Heat exchanger sizing values given as the maximum heat rejection of the circuit, with applied tolerances and an additional 5% reserve factor.
10. Cooling circuit capacity, lube oil capacity, and engine dry weight values are typical.
16. Due to variation between test conditions and final site conditions, such as exhaust configuration and background sound level, sound pressure levels under
site conditions may be different than those tabulated above.
6. Air flow is based on undried air with a tolerance of ± 7%.
15. Engine sound data taken with the microphone at 1 m (3.3 ft) from the side of the engine at the approximate front-to-back centerline. Microphone height was
at intake manifold level. Engine sound pressure data may be different at front, back and opposite side locations. Exhaust sound data taken with microphone 1
meter (3.3 ft) away and 1 meter (3.3 ft) to the side of the exhaust outlet.
3. Fuel consumption is presented in accordance with ISO 3046/1 with a tolerance of -0 / +5% at maximum rating. Fuel flow calculation based on fuel LHV and
fuel consumption with a tolerance of -0/+5 %. For sizing piping and fuel equipment, it is recommended to include the 5% tolerance.
1. All data is based on engines with standard configurations unless noted otherwise.
9. Inlet air restrictions based on full rated engine load. Exhaust backpressure based on 138 PSI BMEP and 900 RPM. Refer to the engine specification section
of Waukesha's standard technical data for more information.
17. Cooling system design flow is based on minimum allowable cooling system flow. Cooling system maximum external restriction is defined as the allowable
restriction at the minimum cooling system flow.
5. Emission levels for engines with Waukesha supplied 3-way catalyst are given at catalyst outlet flange. For all other engine models, emission levels are given
at engine exhaust outlet flange prior to any after treatment. Values are based on a new engine operating at indicated site conditions, and adjusted to the
specified timing and air/fuel ratio at rated load. Catalyst out emission levels represent emission levels the catalyst is sized to achieve. Manual adjustment may
be necessary to achieve compliance as catalyst/engine age. Catalyst-out emission levels are valid for the duration of the engine warranty. Emissions are at an
absolute humidity of 75 grains H2O/lb (10.71 g H2O/kg) of dry air. Emission levels may vary subject to instrumentation, measurement, ambient conditions, fuel
quality, and engine variation. Engine may require adjustment on-site to meet emission values, which may affect engine performance and heat output. NOx,
CO, THC, and NMHC emission levels are listed as a not to exceed limit, all other emission levels are estimated. CO2 emissions based on EPA Federal
Register/Vol. 74, No. 209/Friday, October 30, 2009 Rules and Regulations 56398, 56399 (3) Tier 3 Calculation Methodology, Equation C-5.
4. Heat rejection tolerances are ± 30% for radiation, and ± 8% for jacket water, lube oil, intercooler, and exhaust energy.
7. Exhaust temperature given at engine exhaust outlet flange with a tolerance of ± 50°F (28°C).
8. Exhaust gas mass flow value is based on a "wet basis" with a tolerance of ± 7%.
14. Fuel volume flow calculation in metric units is based on 100% relative humidity of the fuel gas at a combustion temperature of 25°C and metering
conditions of 0°C and 101.325 kPa (14.696 psia; 29.92 inches of mercury). This is expressed as [25, V(0;101.325)].
11. Fuel must conform to Waukesha's "Gaseous Fuel Specification" S7884-7 or most current version. Fuel may require treatment to meet current fuel
specification.
2. Power rating is adjusted for fuel, site altitude, and site air inlet temperature, in accordance with ISO 3046/1 with tolerance of ± 3%.
13. Fuel volume flow calculation in english units is based on 100% relative humidity of the fuel gas at standard conditions of 60°F and 14.696 psia (29.92
inches of mercury; 101.325 kPa).
21. Available Turndown Speed Range refers to the constant torque speed range available. Reduced power may be available at speeds outside of this range.
