RE: Part 70 Operating Permit – Permit Renewal

Title V Permit # V-SUIT-0002-2026.00

SIMCOE, LLC

Treating Site #2 Compressor Station

Ms. Best,

The Southern Ute Indian Tribe Air Quality Division (AQD) has completed its review of SIMCOE,

LLC’s (SIMCOE) request to renew a Title V Permit to Operate, pursuant to the Title V Operating

Permit Program at 40 CFR Part 70, for the Treating Site #2 Compressor Station.

Based on the information submitted in SIMCOE’s application, the AQD hereby issues the enclosed Title

V Permit to Operate. The final permit will become effective on January 16, 2026.

A 30-day public comment period was held from October 31, 2025, to November 30, 2025. The AQD

received no comments from SIMCOE during this time. No comments were received from the public,

affected states, or tribes.

A 45-day Administrative Review period at EPA Region 8 was held from December 2, 2025, to January

15, 2026. No comments were received from EPA Region 8 during this review period.

Pursuant to RAC §2-109(8), within 60 days after the final permit has been issued, the applicant, any person

who participated in the public comment process and is aggrieved by the action, and any other person who

could obtain judicial review of that action under applicable law, may appeal to the Environmental

Commission in accordance with the Southern Ute Indian Tribe/State of Colorado Environmental

Commission’s Reservation Air Code (RAC) and the Commission’s Procedural Rules. Additionally, the

regulations at RAC §2-109(7) specify that any person may petition the EPA Administrator within 60 days

after the expiration of the Administrator’s 45-day review period to make an objection that the permit

would not be in compliance with applicable requirements. Any such petition must be based only on

objections to the permit that were raised with reasonable specificity during the public comment period

unless the petitioner demonstrates that it was impracticable to raise such objections within such period, or

unless the grounds for such objections arose after such period.

If you have any questions concerning the enclosed permit, please feel free to contact me.

Sincerely,

Process Description:

Treating Site #2 is a natural gas production field facility prior to the point of custody transfer.

Fruitland coal bed methane wells feed into a gathering pipeline system leading to the inlet of this

facility. The gas does not contain any condensate or natural gas liquids. The gas from coalbed

methane wells enter the facility and passes through a slug catcher used for water and gas

separation. The water that drops out is stored in water tanks. Each water tank has a tank heater

used during the winter months to heat the water. The produced water in transferred offsite for

disposal. After leaving the slug catcher, the produced gas compressed before passing through one

glycol dehydrator unit equipped with natural gas fired reboilers to further dry the gas.

The facility’s primary pollutant-emitting sources are two compressor engines, a generator engine,

and a tri-ethylene glycol dehydrator. The engines are fueled by natural gas, and one of the

compressors utilizes lean burn technology while the other equipped with catalytic reduction.

Current production at this facility is about 4 MMscfd.

recent form provided by the Tribe.

[RAC 2-118(2)(c)]

1.1.6. Basis for calculating annual fee:

1.1.6.1.

Subtotal annual fees shall be calculated by multiplying the applicable

emission fee set pursuant to RAC §2-119(1) of this code times the total

tons of actual emissions for each fee pollutant. In lieu of actual emissions,

annual fees may be calculated based on the potential to emit for each fee

pollutant. Emissions of any regulated air pollutant that already are

included in the fee calculation under a category of regulated pollutant,

such as a federally listed hazardous air pollutant that is already accounted

for as a VOC or as PM10, shall be counted only once in determining the

source’s actual emissions.

[RAC 2-119(2)(a)]

1.1.6.1.1.

“Actual emissions” means the actual rate of emissions in tpy of

any fee pollutant (for fee calculation) emitted from a Title V

source over the preceding calendar year or any other period

determined by the Tribe to be more representative of normal

operation and consistent with the fee schedule adopted by the Tribe

and approved by the Administrator. Actual emissions shall be

calculated using each emissions units actual operating hours,

production rates, in-place control equipment, and types of

materials processed, stored, or combusted during the preceding

calendar year or other period used for this calculation.

[RAC 1-103(2)]

1.1.6.1.2.

Actual emissions shall be computed using compliance methods

required by the permit.

[RAC 2-118(1)(b)]

1.1.6.1.3.

If actual emissions cannot be determined using the compliance

methods in the permit, the permittee shall use other federally

recognized procedures.

[RAC 2-118(1)(b)]

1.1.6.2.

The total annual fee submitted shall be the greater of the applicable

minimum fee or the sum of subtotal annual fees for all fee pollutants

emitted from the source.

[RAC 2-119(2)(b)]

[Explanatory note: The applicable emission fee amount and applicable minimum fee (if necessary)

are revised each calendar year to account for inflation, and they are available from AQD prior to

the start of each calendar year.]

1.1.6.3.

The permittee shall exclude the following emissions from the calculation

of fees:

1.1.6.3.1.

The amount of actual emissions of any one fee pollutant that the

source emits in excess of 4,000 tpy.

1.1.6.3.2.

Any emissions that come from insignificant activities not required

in a permit application pursuant to RAC §2-106(4).

[RAC 1-103(2)(c)]

1.1.7. Annual fee calculation worksheets shall be certified as to truth, accuracy, and

completeness by a responsible official.

challenge such fee shall provide a written explanation of the alleged error to the

Tribe along with full payment of the assessed fee.

[RAC 2-119(3)(c)]

1.2. Compliance Requirements

1.2.1. Compliance with the Permit

1.2.1.1.

The permittee must comply with all conditions of this part 70 permit. Any

permit noncompliance with federally enforceable or Commission-only

permit conditions constitutes a violation of the RAC and Clean Air Act

and is grounds for enforcement action; for permit termination, revocation

and reissuance, or revision; or for denial of a permit renewal application.

[RAC 2-110(3)(a)]

“prompt” or otherwise specifies a time frame for reporting deviations, that

definition or time frame shall govern.

2.2.4.2.

Where the underlying applicable requirement fails to address the time

frame for reporting deviations, reports of deviations will be submitted

based on the following schedule:

2.2.4.2.1.

For emissions of a hazardous air pollutant or a toxic air pollutant

(as identified in the applicable regulation) that continue for more

than an hour in excess of permit requirements, the report must be

made by email, telephone, verbal, or facsimile communication by

the close of business the next working day, upon discovery of the

occurrence, and in writing within 10 working days from the

occurrence;

2.2.4.2.2.

For emissions of any regulated air pollutant, excluding those listed

in RAC §2-110(7)(b)(i), that continue for more than 2 hours in

excess of permit requirements, the report must be made by email,

[40 CFR 63.6675]

2.2.3. General Compliance Requirements

2.2.3.1.

You must be in compliance with the emission limitations, operating

limitations, and other requirements in this subpart that apply at all times.

[40 CFR 63.6605(a)]

2.2.3.2.

At all times you must operate and maintain any affected source, including

associated air pollution control equipment and monitoring equipment, in a

manner consistent with safety and good air pollution control practices for

minimizing emissions. The general duty to minimize emissions does not

require the permittee to make any further efforts to reduce emissions if

levels required by this standard have been achieved. Determination of

whether such operation and maintenance procedures are being used will be

based on information available to the Tribe which may include, but is not

limited to, monitoring results, review of operation and maintenance

procedures, review of operation and maintenance records, and inspection of

the source.

[40 CFR 63.6605(b)]

2.2.4.

Testing and Initial Compliance Requirements

2.2.4.1.

You must operate and maintain the stationary RICE and after-treatment

control device (if any) according to the manufacturer’s emission related

written instructions or develop your own maintenance plan which must

provide to the extent practicable for the maintenance and operation of the

engine in a manner consistent with good air pollution control practice for

minimizing emissions.

[40 CFR 63.6625(e)]

2.2.4.2.

You must minimize the engines’s time spent at idle during startup and

minimize the engine’s startup time to a period needed for appropriate and

safe loading of the engine, not to exceed 30 minutes, after which time the

emissions standards applicable to all times other than startup in Table 2d

apply.

40 CFR 63.6625(h)]

2.2.4.3.

You have the option of utilizing an oil analysis program in order to extend

the specified oil and filter change requirement in Table 2d to this subpart.

The oil analysis must be performed at the same frequency specified for

changing the oil and filter in Table 2d to this subpart. The analysis program

must at a minimum analyze the following three parameters: Total Acid

Number, viscosity, and percent water content. The condemning limits for

these parameters are as follows: Total Acid Number increases by more than

3.0 milligrams of potassium hydroxide (KOH) per gram from Total Acid

Number of the oil when new; viscosity of the oil has changed by more than

20 percent from the viscosity of the oil when new; or percent water content

(by volume) is greater than 0.5. If all of these condemning limits are not

exceeded, the engine owner or operator is not required to change the oil. If

any of the limits are exceeded, the engine owner or operator must change

the oil within 2 business days of receiving the results of the analysis; if the

engine is not in operation when the results of the analysis are received, the

engine owner or operator must change the oil within 2 business days or

before commencing operation, whichever is later. The owner or operator

must keep records of the parameters that are analyzed as part of the

program, the results of the analysis, and the oil changes for the engine. The

analysis program must be part of the maintenance plan for the engine.

[40 CFR 63.6625(j)]

Reserved – Consent Decree Requirements

Compliance Assurance Monitoring (CAM) Requirements

6.1. 40 CFR Part 64 Compliance Assurance Monitoring [40 CFR 64.1 – 40 CFR 64.10]

Notwithstanding the conditions in this permit, the permittee shall comply with all

applicable conditions of 40 CFR Part 64 - CAM.

6.1.1. The CAM requirements specified at 40 CFR Part 64 apply to the following emission

units with respect to the NOx and CO emission limits identified in the PSD Permit

Requirements section of this permit.

TS2-1 - Waukesha L5790GSI 4SRB SI Natural Gas-Fired Compressor

Engine, 1,215 Nameplate Rated HP[

TS2-2* - Waukesha L5790GSI 4SRB SI Natural Gas-Fired Compressor

Engine, 1,215 Nameplate Rated HP

[40 CFR 64.2]

TS2-2 was removed from the site in 2022. However, the engine remains in the Part 70 permit as

they are still listed in the PSD permit for the facility.

6.1.2. Excursions, as defined in the CAM plan, shall be reported in accordance with the

Facility-Wide Reporting Requirements section of this permit.

6.1.3. Operation of Approved Monitoring

6.1.3.1.

At all times, the owner or operator shall maintain the monitoring,

including but not limited to, maintaining necessary parts for routine

repairs of the monitoring equipment.

[40 CFR 64.7(b)]

6.1.3.2.

Except for, as applicable, monitoring malfunctions, associated

repairs, and required quality assurance or control activities

(including, as applicable, calibration checks and required zero and

span adjustments, the owner or operator shall conduct all monitoring

in continuous operation (or shall collect data on all required levels)

at all times that the pollutant-specific emissions unit is operating,

Data recorded during monitoring malfunction, associated repairs,

and required quality assurance or control activities shall not be used

for purposes of these CAM requirements, including data averages

and calculation, or fulfilling a minimum data availability

requirement, if applicable. The owner or operator shall use all the

data collected during all other periods in assessing the operation of

the control device and associated control system. A monitoring

malfunction is any sudden, infrequent, not reasonably preventable

failure of the monitoring to provide valid data. Monitoring failures

that are caused in part by poor maintenance or careless operation are

not malfunctions.

[40 CFR 64.7(c)]

6.1.3.3.

Upon detecting an excursion or exceedance, the owner or operator

shall restore operation of the pollutant-specific emissions unit

(including the control device and associated capture system) to its

normal or usual manner of operation as expeditiously as practicable

in accordance with good air pollution control practices for

minimizing emissions. The response shall include minimizing the

period of any startup, shutdown or malfunction and taking any

necessary corrective actions to restore normal operation and prevent

the likely recurrence of the cause of an excursion or exceedance

(other than those caused by excused startup or shutdown

conditions). Such actions may include initial inspection and

evaluation, recording that operations returned to normal without

operator action (such as through response by a computerized

distribution control system), or any necessary follow-up actions to

return operation to within the indicator range, designated condition

or below the applicable emission limitation or standard, as

applicable.

[40 CFR 64.7(d)(1)]

6.1.3.4.

Determination of whether the owner of operator has used acceptable

procedures in response to an excursion or exceedance will be based

on information available, which may include but is not limited to,

monitoring results, review of operation and maintenance procedures

and records, and inspection of the control device, associated capture

system, and the process.

[40 CFR 64.7(d)(2)]

6.1.3.5.

After approval of the monitoring required under the CAM

requirements, if the owner or operator identifies a failure to achieve

compliance with an emission limitation or standard for which the

approved monitoring did not provide an indication of an excursion

or exceedance while providing valid data, or the results of

compliance or performance testing document a need to modify the

existing indicator ranges or designated conditions, the owner or

operator shall promptly notify the Tribe and, if necessary submit a

proposed modification for this permit to address the necessary

monitoring changes. Such a modification may include, but is not

limited to, reestablishing indicator ranges or designated conditions,

modifying the frequency of conducting monitoring and collecting

data, or the monitoring of additional parameters.

[40 CFR 64.7(e)]

6.1.4. Based on the results of a determination made under §64.7(d)(2), the Tribe or EPA

may require the permittee to develop and implement a Quality Improvement Plan

(QIP) in accordance with §64.8.

[40 CFR 64.8]

6.1.5. The permittee shall submit monitoring reports in accordance with §64.9(a) for

CAM requirements on a semi-annual basis to the Tribe as specified in the FacilityWide Reporting Requirements section in this permit.

[40 CFR 64.8(a)]

6.1.6. The permittee shall maintain records of monitoring data, monitor performance data,

corrective actions taken, any written QIP and any activities undertaken to

implement a QIP, and any other supporting information required to be maintained

under Part 64 (such as data used to document the adequacy of monitoring, or

records of monitoring maintenance or corrective actions as specified in §64.9(b)).

[40 CFR 64.9(b)(1)]

Enhanced Monitoring, Recordkeeping, and Reporting
