Re:

Final Part 70 Operating Permit

Title V Permit #V-SUIT-0031-2020.00

Red Cedar Gathering Company

South Ignacio Central Delivery Point

Dear Mr. Hunderman:

The Southern Ute Indian Tribe Air Quality Program (AQP) has completed its review of Red Cedar

Gathering Company’s (Red Cedar) request to renew a Title V Permit to Operate pursuant to the Title V

Operating Permit Program at 40 CFR Part 70, for the South Ignacio Central Delivery Point.

Based on the information submitted in the company’s application, the Tribe hereby issues the enclosed

Title V Permit to Operate. The final permit will become effective on June 14, 2021.

A 30-day public comment period was held from March 12, 2021 to April 11, 2021. The Tribe received

no comments from Red Cedar during this time and no comments were received from the public, affected

states, or tribes.

On March 24, 2021, Red Cedar identified an incorrect VOC emission factor in the Part 70 renewal

application for South Ignacio Central Delivery Point. As per Reservation Air Code §2-106(5) - Duty to

Supplement and Correct, Red Cedar submitted an application revision to correct the emission factor and

the potential to emit. The correction resulted in a decrease in VOC emissions but did not result in any

change to regulatory applicability.

A 45-day Administrative Review period at EPA Region 8 was held from April 27, 2021 to June 11,

2021. 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 contact Matt Wampler at 970-563-2202.

Sincerely,

Matt Wampler

Process Description:

The South Ignacio Central Delivery Point (CDP) is owned by Red Cedar Gathering Company.

The facility is located within the exterior boundaries of the Southern Ute Indian Reservation in

Section 32, Township 33 North, Range 7 West in La Plata County, Colorado.

The facility is comprised of equipment that dehydrates and compresses coal-bed methane gas from

several wells to transmission pipeline specifications. Gas entering the facility from the field is

first fed to an inlet separator that gravimetrically removes water that may have formed / condensed

during transportation from the supplying gas wells. Separator overhead gas is fed to one of the

eight compressor engines from a common suction header. The compressors discharge gas to a

common discharge header that feeds to scrubbers. The scrubbers separate and collect liquids that

may have formed during compression. The compressed gas is then fed to two dehydration units.

Tri-ethylene glycol is circulated counter-currently and absorbs water from the saturated gas. Rich

glycol is circulated to a reboiler, where moisture is driven to the atmosphere by heating the glycol.

Dry gas exits the contactors and is directed to the sales line, where it is metered and exits the

facility. The gas processing capacity of the facility is approximately 70 MMscfd with eight

compressor engines operating.

Process equipment installed at the facility consists of eight natural gas-fired reciprocating engines,

two Triethylene glycol dehydration units equipped with reboiler burners. There are several

insignificant emission units at this facility including various tanks and heaters.

by the same deadline as required for fee payment to the address listed in the

Submissions section of this permit.

[RAC 2-118]

1.1.5. Basis for calculating annual fee:

1.1.5.1.

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)]

1.1.5.1.1.

“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, inplace 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)]

1.1.5.1.2.

Actual emissions shall be computed using compliance methods

required by the permit.

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

1.1.5.1.3.

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)]

1.1.5.2.

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 AQP prior to

the start of each calendar year.]

1.1.5.3.

The permittee shall exclude the following emissions from the calculation of

fees:

1.1.5.3.1.

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

source emits in excess of 4,000 tons per year

1.1.5.3.2.

Any emissions that come from insignificant activities not required

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

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

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

completeness by a responsible official.

[RAC 2-105 and RAC 2-118(2)(c)]

assessment of penalties and interest in accordance with RAC § 2-118(6).

[RAC 2-118(6)]

1.1.8. When notified by the Tribe of underpayment of fees, the permittee shall remit full

payment within 30 days of receipt of an invoice from the Tribe.

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

1.1.9. A permittee who thinks a Tribe assessed fee is in error and who wishes to challenge

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

with full payment of the assessed fee.

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)]

1.2.1.2.

It shall not be a defense for a permittee in an enforcement action that it

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.

for measuring NOX and CO emissions to demonstrate

compliance with the emissions limitations in this permit. The

performance tests shall be conducted in accordance with

appropriate reference methods specified in Table 2 to

Subpart JJJJ of 40 CFR part 60. The Permittee may submit

to the EPA a written request for approval of an alternate test

method but shall only use that alternate test method after

obtaining written approval from the EPA.

3.1.2.4.1.1.

The initial performance test shall be conducted

within 90 calendar days of startup of a new engine.

The results of performance tests conducted prior to

the effective date of this permit may be used to

demonstrate compliance with the initial performance

test requirements, provided the tests were conducted

in an equivalent manner as the performance test

requirements in this permit.

3.1.2.4.1.2.

Performance tests shall be conducted within 90

calendar days of startup of a rebuilt and replaced

engine.

3.1.2.4.1.3.

Performance tests shall be conducted within 90

calendar days of startup after each catalyst

replacement.

3.1.2.4.1.4.

Subsequent performance tests for NOX and CO

emissions shall be performed semiannually.

3.1.2.4.1.4.1.

If the results of two consecutive subsequent

semiannual performance tests demonstrate

compliance with NOX and CO emissions

limits, required testing frequency for NOX

and CO may change from semi-annually to

annually.

3.1.2.4.1.4.2.

If the results of any subsequent annual

performance

test

demonstrate

non50

compliance with the NOX or CO emissions

limits, required monitoring frequency for

NOX and CO shall change back to

semiannually.

3.1.2.4.2.

The Permittee shall not perform engine tuning or make any

adjustments to engine settings, catalytic control system

settings, processes or operational parameters immediately

prior to the engine testing or during the engine testing. Any

such tuning or adjustments may result in a determination by

the EPA that the test is invalid. Artificially increasing an

engine load to meet test requirements is not considered

engine tuning or adjustments.

3.1.2.4.3.

The Permittee shall not abort any engine tests that

demonstrate non-compliance with any NOX and CO

emissions limits in this permit.

3.1.2.4.4.

Performance tests conducted on the 4SRB engine for

measuring NOX and CO emissions shall meet the following

requirements:

3.1.2.4.4.1.

The pressure drop across the catalyst bed and the

inlet temperature to the catalyst bed shall be

measured and recorded during all performance tests;

3.1.2.4.4.2.

All performance tests for NOX and CO emissions

shall be performed simultaneously;

3.1.2.4.4.3.

All performance tests shall be conducted at a

maximum operating rate (90% to 110% of the

maximum achievable engine load available on the

day of the test). The Permittee may submit to the

EPA a written request for approval of an alternate

load level for testing, but shall only test at that

alternate load level after obtaining written approval

from the EPA;

3.1.2.4.4.4.

During each test run, data shall be collected on all

parameters necessary to document how emissions

were measured and calculated (such as test run

length, minimum sample volume, volumetric flow

rate, moisture and oxygen corrections, etc.);

3.1.2.4.4.5.

Each test shall consist of at least three 1-hour or

longer valid test runs. Emission results shall be

reported as the arithmetic average of all valid test

runs and shall be in terms of the emissions limits in

this permit;

3.1.2.4.4.6.

Performance test plans shall be submitted to the EPA

for approval at least 60 calendar days prior to the date

the test is planned;

3.1.2.4.4.7.

Performance test plans that have already been

approved by the EPA for the emission units approved

in this permit may be used in lieu of new test plans

unless the EPA requires the submittal and approval

of new test plans. The Permittee may submit new

plans for EPA approval at any time; and

3.1.2.4.4.8.

The test plans shall include and address the following

elements:

3.1.2.4.4.8.1.

locations,

test

methods,

laboratory

identification);

3.1.2.4.4.8.5.

Quality

assurance

plan

(calibration

procedures and frequency, sample recovery

and field documentation, chain of custody

procedures); and

3.1.2.4.4.8.6.

Data processing and reporting (description of

data handling and quality control procedures,

report content).

3.1.2.4.5.

The Permittee shall notify the EPA and the Southern Ute

Indian Tribe at least 30 calendar days prior to scheduled

performance testing. The Permittee shall notify the EPA at

least 1 week prior to scheduled performance testing if the

testing cannot be performed.

3.1.2.4.6.

If the results of a complete and valid performance test of the

emissions from the permitted engine demonstrates

noncompliance with the emissions limits in this permit, the

engine shall be shut down as soon as safely possible, and

appropriate corrective action shall be taken (e.g., repairs,

catalyst cleaning, catalyst replacement). The Permittee shall

notify the EPA and the Southern Ute Indian Tribe in writing

within 24 hours of each such shut down. The engine must be

retested within 7 days of being restarted and the emissions

must meet the applicable limits in this permit. If the retest

shows that the emissions continue to exceed the limits in this

permit, the engine shall again be shut down as soon as safely

possible, and the engine may not operate, except for

purposes of startup and testing, until the Permittee

demonstrates through testing that the emissions do not

exceed the emissions limits in this permit.

3.1.2.4.7.

If a permitted engine is not operating, the Permittee does not

need to start up the engine solely to conduct a performance

test. The Permittee may conduct the performance test when

the engine is started up again.

3.1.2.5.

Monitoring Requirements

3.1.2.5.1.

The Permittee shall continuously measure the engine

exhaust temperature at the inlet to the catalyst bed on the

engine.

3.1.2.5.2.

Except during startups not to exceed 30 minutes, if the

engine exhaust temperature at the inlet to the catalyst bed

deviates from the acceptable ranges specified in this permit

then the following actions shall be taken. The Permittee’s

completion of any or all of these actions shall not constitute,

nor qualify as, an exemption from any other emissions limits

in this permit:

3.1.2.5.2.1.

Within 24 hours upon determining a deviation of the

engine exhaust temperature at the inlet to the catalyst

bed, the Permittee shall investigate and document

when an investigation is initiated, what the

investigation consisted of and when the investigation

is completed. The investigation shall include testing

the temperature sensing device, inspecting the engine

for performance problems and assessing the catalytic

control system for possible damage that could affect

catalytic system effectiveness (including, but not

limited to, catalyst housing damage and fouled,

destroyed or poisoned catalyst).

3.1.2.5.2.2.

If the engine exhaust temperature at the inlet to the

catalyst bed can be corrected by following the engine

manufacturer’s recommended procedures or

equivalent procedures developed by the Permittee or

vendor and the catalytic control system has not been

damaged, then the Permittee shall correct the engine

exhaust temperature at the inlet to the catalyst bed

within 24 hours of inspecting the engine and catalytic

control system.

3.1.2.5.2.3.

If the engine exhaust temperature at the inlet to the

catalyst bed cannot be corrected using the engine

manufacturer

recommended

procedures

equivalent procedures developed by the Permittee or

vendor, or the catalytic control system has been

damaged, then the affected engine shall cease

operating immediately and shall not be returned to

routine service until the following has been met:

3.1.2.5.2.3.1.

The engine exhaust temperature at the inlet to

the catalyst bed is measured and found to be

within the acceptable temperature range for

that engine; and

3.1.2.5.2.3.2.

The catalytic control system has been

repaired or replaced, if necessary.

3.1.2.5.3.

The Permittee shall monitor the pressure drop across the

catalyst bed of the engine once every calendar month using

pressure sensing devices before and after the catalyst bed to

obtain a direct reading of the pressure drop (also referred to

as the differential pressure). [Note to Permittee: Differential

pressure measurements, in general, are used to show the

pressure across the filter elements. This information will

determine when the elements in the catalyst bed are fouling,

blocked or blown out and thus require cleaning or

replacement.]

3.1.2.5.4.

The Permittee shall perform the first measurement of the

pressure drop across each catalyst bed no more than 30

calendar days from the date of the initial performance test.

Thereafter, the Permittee shall measure the pressure drop

across the catalyst bed, at a minimum once a calendar month.

Subsequent performance tests, as required in this permit, can

be used to meet the periodic pressure drop monitoring

requirement for that month. The pressure drop reading can

be a one-time measurement on that day, the average of

measurements taken during performance test runs, or a 12hour average of all the measurements on that day if

continuous readings are taken.

3.1.2.5.5.

If the pressure drop reading exceeds ± 2 inches of water from

the baseline pressure drop reading taken during the most

recent performance test, then the following actions shall be

taken. The Permittee’s completion of any or all of these

actions shall not constitute, nor qualify as, an exemption

from any other emissions limits in this permit:

3.1.2.5.5.1.

Within 24 hours of determining a deviation of the

pressure drop across the catalyst bed, the Permittee

shall investigate and document when an

investigation is initiated, what the investigation

consisted of and when the investigation is completed.

The investigation shall include testing the pressure

transducers and assessing the catalytic control

system for possible damage that could affect

catalytic system effectiveness (including, but not

limited to, catalyst housing damage, and plugged,

fouled, destroyed or poisoned catalyst).

3.1.2.5.5.2.

If the pressure drop across the catalyst bed can be

corrected by following the catalytic control system

manufacturer’s recommended procedures or

equivalent procedures developed by the Permittee or

vendor, and the catalytic control system has not been

damaged, then the Permittee shall correct the

problem within 24 hours of inspecting the catalytic

control system.

3.1.2.5.5.3.

If the pressure drop across the catalyst bed cannot be

corrected using the catalytic control system

manufacturer’s recommended procedures or

equivalent procedures developed by the Permittee or

vendor, or the catalytic control system is damaged,

then the Permittee shall do one of the following:

3.1.2.5.5.3.1.

Conduct a performance test as specified in

this permit to ensure that the emissions limits

are being met and to re-establish the pressure

drop across the catalyst bed; or

3.1.2.5.5.3.2.

Cease operating the affected engine

immediately. The engine shall not be

returned to routine service until the pressure

drop is measured and found to be within the

acceptable pressure range for that engine as

determined from the most recent

performance test. Corrective action may

include removal and cleaning of the catalyst

or replacement of the catalyst.

3.1.2.5.6.

The Permittee is not required to conduct parametric

monitoring of exhaust temperature and catalyst differential

pressure on engines that have not operated during the

monitoring period. The Permittee shall certify that the

engine did not operate during the monitoring period in the

annual report specified in this permit.

3.1.2.6.

Recordkeeping Requirements

3.1.5. General Provisions / Conditional Approval

Pursuant to the authority of 40 CFR 49.151, the EPA hereby conditionally

grants this permit.

This authorization is expressly conditioned as follows:

3.1.5.1.

Document Retention and Availability: This permit and any required

attachments shall be retained and made available for inspection

upon request at the location set forth herein.

3.1.5.2.

Permit Application: The Permittee shall abide by all representations,

statements of intent and agreements contained in the application

submitted by the Permittee. The EPA shall be notified 10 days in

advance of any significant deviation from this permit application as

well as any plans, specifications or supporting data furnished.

3.1.5.3.

Permit Deviations: The issuance of this permit may be suspended or

revoked if the EPA determines that a significant deviation from the

permit application, specifications, and supporting data furnished has

been or is to be made. If the proposed source is constructed,

operated, or modified not in accordance with the terms of this

permit, the Permittee will be subject to appropriate enforcement

action.

3.1.5.4.

Compliance with Permit: The Permittee shall comply with all

conditions of this permit, including emissions limitations that apply

to the affected emissions units at the permitted facility/source.

Noncompliance with any permit term or condition is a violation of

this permit and may constitute a violation of the Clean Air Act and

is grounds for enforcement action and for a permit termination or

revocation.

3.1.5.5.

Fugitive Emissions: The Permittee shall take all reasonable

precautions to prevent and/or minimize fugitive emissions during

the construction period.

3.1.5.6.

NAAQS and PSD Increment: The permitted source shall not cause

or contribute to a NAAQS violation or a PSD increment violation.

3.1.5.7.

Compliance with Federal and Tribal Rules, Regulations, and

Orders: Issuance of this permit does not relieve the Permittee of the

responsibility to comply fully with all other applicable federal and

tribal rules, regulations, and orders now or hereafter in effect.

3.1.5.8.

Enforcement: It is not a defense, for the Permittee, in an enforcement

action, to claim that it would have been necessary to halt or reduce

the permitted activity in order to maintain compliance with the

conditions of this permit.

3.1.5.9.

Modifications of Existing Units/Limits: For proposed modifications,

as defined at 40 CFR 49.152(d), that would increase an emissions

unit’s allowable emissions of a pollutant above its existing permitted

annual allowable emissions limit, the Permittee shall first obtain a

permit modification pursuant to the MNSR regulations approving

the increase. For a proposed modification that is not otherwise

subject to review under the PSD or MNSR regulations, such

proposed increase in the annual allowable emissions limit shall be

approved through an administrative permit revision as provided at

40 CFR 49.159(f).

3.1.5.10.

Relaxation of Legally and Practically Enforceable Limits: At such

time that a new or modified source within this permitted

facility/source or modification of this permitted facility/source

becomes a major stationary source or major modification solely by

virtue of a relaxation in any legally and practically enforceable

limitation which was established after August 7, 1980, on the

capacity of this permitted facility/source to otherwise emit a

pollutant, such as a restriction on hours of operation, then the

requirements of the PSD regulations shall apply to the source or

modification as though construction had not yet commenced on the

source or modification.

3.1.5.11.

Revise, Reopen, Revoke and Reissue, or Terminate for Cause: This

permit may be revised, reopened, revoked and reissued, or

terminated for cause. The filing of a request by the Permittee, for a

permit revision, revocation and reissuance, or termination, or of a

notification of planned changes or anticipated noncompliance does

not stay any permit condition. The EPA may reopen this permit for

a cause on its own initiative, e.g., if this permit contains a material

mistake or the Permittee fails to assure compliance with the

applicable requirements.

3.1.5.12.

Severability Clause: The provisions of this permit are severable, and

in the event of any challenge to any portion of this permit, or if any

portion is held invalid, the remaining permit conditions shall remain

valid and in force.

3.1.5.13.

Property Rights: This permit does not convey any property rights of

any sort or any exclusive privilege.

3.1.5.14.

Information Requests: The Permittee shall furnish to the EPA,

within a reasonable time, any information that the EPA may request

in writing to determine whether cause exists for revising, revoking

and reissuing, or terminating this permit or to determine compliance

with this permit. For any such information claimed to be

confidential, you shall also submit a claim of confidentiality in

accordance with 40 CFR part 2, subpart B.

3.1.5.15.
