Re:

Final Part 70 Operating Permit

Title V Permit #V-SUIT-0023-2022.00

Public Service Company of Colorado

Tiffany Compressor Station

Dear Mr. Campbell:

The Southern Ute Indian Tribe Air Quality Division (Tribe) has completed its review of Public Service

Company of Colorado (PSCo) request to renew a Title V Permit to Operate pursuant to the Title V

Operating Permit Program at 40 CFR Part 70, for the Tiffany Compressor Station.

Based on the information submitted in the company’s application, and the comments received during the

public comment period, the Tribe hereby issues the enclosed Title V Permit to Operate. The final permit

will become effective on February 12, 2024.

A 30-day public comment period was held from November 22, 2023 to December 22, 2023. The Tribe

received no comments from PSCo during this time and 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 27, 2023 to February

10, 2024. No comments were received from EPA Region 8 during this review period.

During the Administrative Review period, the Tribe identified the need to remove the emergency

affirmative defense provisions from the permit, due to the EPA’s finalization on August 21, 2023, of

the rulemaking titled Removal of Title V Emergency Affirmative Defense Provisions From State

Operating Permit Programs and Federal Operating Permit Program. The final rulemaking

required permitting authorities with affirmative defense permit terms based on 40 CFR 70.6(g), to

remove the affirmative defense provisions from Title V operating permits by the next permit renewal

that occurs following the effective date of the EPA rulemaking. EPA Region 8 was notified of this

change to the draft permit.

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 Tiffany Compressor Station conditions natural gas to pipeline quality for delivery to Xcel

Energy, Public Service Company of Colorado (PSCo) customers. The facility compresses natural

gas using three compressor engines and removes water from the gas stream using three

dehydrators. The gas is then odorized and delivered into a PSCo pipeline that provides gas to

Pagosa Springs, the San Luis Valley, and the PSCo mountain customers. This facility is classified

as a natural gas transmission facility defined under Standard Industrial Classification 4922.

The primary emission sources are three natural gas-fired four-stroke rich-burn (4SRB) spark

ignition (SI) compressor engines and three triethylene glycol (TEG) dehydrators.

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 tons per year.

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.

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

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)]

2006.

[40 CFR 63.6585]

2.1.2. Emission and Operating Limitations

2.1.2.1.

If you own or operate an existing stationary RICE located at an area

source of HAP emissions, you must comply with the requirements in

Table 2d to this subpart and the operating limitations in this subpart that

apply to you.

[40 CFR 63.6603]

Table 2d to Subpart ZZZZ of Part 63 – Requirements for Existing Stationary RICE

Located at Area Sources of HAP Emissions

As stated in §63.6603 and §63.6640, you must comply with the following requirements for existing stationary

RICE located at area sources of HAP emissions:

For Each…

11. Non-emergency, nonblack start 4SRB remote

stationary RICE >500 HP

You must meet the following

emission limitation, except during

periods of startup…

a. Change oil and filter every 2,160

hours of operation or annually,

whichever comes first1;

b. Inspect spark plugs every 2,160

hours of operation or annually,

whichever comes first, and replace as

necessary; and

c. Inspect all hoses and belts every

2,160 hours of operation or annually,

whichever comes first, and replace as

necessary.

During periods of start

up you must…

Minimize the engine's

time spent at idle and

minimize the engine's

startup time at startup to

a period needed for

appropriate and safe

loading of the engine,

not to exceed 30

minutes, after which

time the non-startup

emission limitations

apply.

Sources have the option to utilize an oil analysis program as described in §63.6625(i) or (j) in order to extend the

specified oil change requirement in Table 2d of this subpart.

If an emergency engine is operating during an emergency and it is not possible to shut down the engine in order to

perform the management practice requirements on the schedule required in Table 2d of this subpart, or if performing

the management practice on the required schedule would otherwise pose an unacceptable risk under federal, state, or

local law, the management practice can be delayed until the emergency is over or the unacceptable risk under

federal, state, or local law has abated. The management practice should be performed as soon as practicable after the

emergency has ended or the unacceptable risk under federal, state, or local law has abated. Sources must report any

failure to perform the management practice on the schedule required and the federal, state or local law under which

the risk was deemed unacceptable.

2.1.2.2.

For emission units E001, E002 and E003: you must evaluate the status of

their stationary RICE every 12 months. Owners and operators must keep

records of the initial and annual evaluation of the status of the engine. If

the evaluation indicates that the stationary RICE no longer meets the

definition of remote stationary RICE in §63.6675 of this subpart, the

owner or operator must comply with all of the requirements for existing

non-emergency SI 4SRB stationary RICE with a site rating of more than

500 HP located at area sources of HAP that are not remote stationary

RICE within 1 year of the evaluation.

[40 CFR 63.6603]

2.1.2.2.1.

In accordance with §63.6675, for stationary RICE located on a

pipeline segment, Remote Stationary RICE must meet the criteria

listed below:

2.1.2.2.1.1.

A pipeline segment with 10 or fewer buildings intended

for human occupancy and no buildings with four or more

stories within 220 yards (200 meters) on either side of the

centerline of any continuous 1-mile (1.6 kilometers) length

of pipeline. Each separate dwelling unit in a multiple

dwelling unit building is counted as a separate building

intended for human occupancy.

2.1.2.2.1.2.

The pipeline segment does not lie within 100 yards (91

meters) of either a building or a small, well-defined outside

area (such as a playground, recreation area, outdoor theater,

or other place of public assembly) that is occupied by 20 or

more persons on at least 5 days a week for 10 weeks in any

12-month period. The days and weeks need not be

consecutive. The building or area is considered occupied

for a full day if it is occupied for any portion of the day.

2.1.2.2.1.3.

For purposes of this section, the term pipeline segment

means all parts of those physical facilities through which

gas moves in transportation, including but not limited to

pipe, valves, and other appurtenance attached to pipe,

compressor units, metering stations, regulator stations,

delivery stations, holders, and fabricated assemblies.

Stationary RICE located within 50 yards (46 meters) of the

pipeline segment providing power for equipment on a

pipeline segment are part of the pipeline segment.

Transportation of gas means the gathering, transmission, or

distribution of gas by pipeline, or the storage of gas. A

building is intended for human occupancy if its primary use

is for a purpose involving the presence of a humans.

[40 CFR 63.6603 and 63.6675]

2.1.3. General Compliance Requirements

2.1.3.1.

You must be in compliance with operating limitations and other

requirements in this subpart that apply to you at all times.

2.1.3.2.

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 you 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 Administrator 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]

2.1.4. Testing and Initial Compliance Requirements

2.1.4.1.

For emission units E001, E002 and E003: you must minimize the engine'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 emission standards applicable to

all times other than startup in Table 2d to subpart ZZZZ apply.

2.1.4.2.

For emission units E001, E002 and E003: you have the option of utilizing

an oil analysis program in order to extend the specified oil change

requirement in Table 2d to this subpart. The oil analysis must be

performed at the same frequency specified for changing the oil 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]

2.1.5. Continuous Compliance Requirements
