Background:

The South Oakford Compressor Station is a natural gas compressor station, with two, NG-fired, 6,350-bhp, compressor engines, one, NG-fired, 778-bhp, emergency generator engine, and one, NG-fired, 3.347 MMBtu/hr boiler. The Department’s earliest records of the station are from 1994.

On November 16, 1995, CNG Transmission Corporation submitted an application for an initial Title V Operating Permit (TVOP) for the South Oakford Compressor Station. On October 13, 1996, the Department issued a Reasonably Available Control Technology Permit, RACT-65-000-840 for the station. On July 17, 1998, the initial TVOP, which was the first facility-wide permit for the station, was issued with an expiration date of July 17, 2003.

During the year 2000, Consolidated Natural Gas Company (the parent company of CNGT) was merged with Dominion Resources Inc., and Dominion became the owner of the facility. On December 26, 2002, Dominion submitted an application to renew the TVOP. On October 31, 2007, the renewed permit was issued with an expiration date of October 31, 2012. The two parts washers (Source ID 111) at the facility were added as a subfacility, as part of this renewal.

On January 11, 2012, Dominion Transmission, Inc. submitted an application to, again renew the TVOP for the South Oakford Compressor Station. Since that time, the name of the owner has changed to Dominion Energy Transmission, Inc.

On June 3, 2016, Dominion submitted an application to install a Clean Burn System on each of the two compressor engines (Source IDs 101 and 102). This included improved engine components which included cylinder heads, pistons, cylinder liners, and turbochargers. In addition, on June 16, 2016, the Department received a petition for an Alternate Compliance Schedule for compliance with the requirements of RACT II for the compressor engines. The final compliance date requested in the petition was February 16, 2018. On April 18, 2017, the Department mailed its approval of both of these requests to the company in the form of a reply to a Request for Determination RFD - 65 - 00840A.

On October 24, 2016, the company submitted an application for a Modification, to incorporate the requirements of RACT II into the Title Operating Permit. This application requested that a limit be placed on the annual operating time of the Aux. Emergency Generator Engine (Source ID 103). No other changes have been made to the sources or controls at the facility since December 2002. These applications are the subject of the Technical Review Document (TRD). The proposed TVOP renewal incorporates both applications.

On December 19 and 20, 2017, both compressor engines (Source IDs 101 and 102) were tested for NOx, CO, and VOC. The results demonstrated compliance with the presumptive NOx and VOC emission limits established to comply with the requirements of RACT II. The testing completed all changes, whose delayed performance was authorized by the Alternate Compliance Schedule, prior to the final performance date of February 16, 2018.

(Values effective January 1, 2014.) 2Emissions from the boiler are based on AP-42, Table 1.4-2. 3Emissions from the engines are based on AP-42, Table 3.2-1 & Table 3.2-3. 4Blow-by emissions from the compressor are based on 23 (11.5 * 2) scfh/piston rod (EPA EnergyStar), 8 piston rods, and NG analysis supplied by the company, in its 2015 annual

report. 5Methane emissions from P01 are based on CH4 emissions from the natural gas compressors and the ratio of VOC from the two sources. Values reported in this table were rounded from calculations performed elsewhere. Total facility emissions are a combination of regulated potential emissions and estimated emissions.

The use of Clean Burn Technology has a negligible effect on emissions of CO2e. However, the reduction in authorized operation of the emergency engine lowered emissions from this source.

The South Oakford Compressor Station is a Title V source, because its potential emissions of NOx and CO are greater than the Major Source threshold of 100 tons per year and VOC are greater than the Major Source threshold of 50 tons per year. Its annual emissions of PM2.5, PM10, and SO2 from the facility are less than the Major Source threshold of 100 tons per year. For Hazardous Air Pollutant (HAP) emissions, the facility has a single HAP (Formaldehyde) with an emission potential greater than the 10 TPY major source threshold. This means that South Oakford is also a Major Source of HAP emissions. Finally, CO2e emissions from South Oakford are less than the Major Source threshold of 100,000 tpy. Therefore, South Oakford is a minor source of CO2e.

The facility was evaluated for the applicability of New Source Performance Standards (NSPS), National Emission Standards for Hazardous Air Pollutants (NESHAP), other Federal Standards, and applicable requirements of 25 Pa. Code Chapters 121 - 145, of the Commonwealth of Pennsylvania. The following standards were considered:

Table 5: Regulatory Analysis Dominion Energy Transmission, Inc.

South Oakford Compressor Station (TVOP-65-00840) Federal Regulations

NSPS

40 CFR Part 60, Subpart Kb - Standards of Performance for Volatile Organic Liquid Storage Vessels (Including Petroleum Liquid Storage Vessels) for Which Construction, Reconstruction, or Modification Commenced After July 23, 1984.

Any condensate stored in storage vessels at the South

Oakford Compressor Station does not have sufficient

vapor pressure for Subpart Kb to have any applicable

requirements for these tanks.

40 CFR Part 60, Subpart LLL - Standards of Performance for SO2 Emissions From Onshore Natural Gas Processing for Which Construction, Reconstruction, or Modification Commenced After January 20, 1984, and on or Before August 23, 2011.

South Oakford compresses pipeline quality natural gas,

and does not have equipment which “sweetens” the

natural gas. This Subpart regulates removal of acid gas

(H2S and SO2). No source at the facility has applicable

requirements under the Subpart.

40 CFR Part 60, Subpart JJJJ - Standards of Performance for Stationary Spark Ignition Internal Combustion Engines.

This Subpart applies to SI engines larger than 500-bhp,

constructed after July 1, 2007, and lean burn SI engines,

rated greater than 1,350 HP, manufactured after

January 1, 2008. The SI engines at South Oakford pre-

date this Subpart, and have no applicable requirements

under it. (Continued)

Dominion Energy Transmission, Inc. South Oakford Compressor Station TVOP-65-00840

11

(Table 5 NSPS - Continued)

40 CFR Part 60, Subpart KKKK - Standards of Performance for Stationary Combustion Turbines.

The facility has no combustion turbines. No source at

the facility has applicable requirements under the

Subpart.

40 CFR Part 60, Subpart OOOO - Standards of Performance for Crude Oil and Natural Gas Production, Transmission and Distribution for which Construction, Modification or Reconstruction Commenced after August 23, 2011, and on or before September 18, 2015.

South Oakford is not a natural gas processing plant, and

only its compressors could have requirements under the

subpart. The natural gas compressors were constructed

before this time. This Subpart is not applicable to any

source at South Oakford.

40 CFR Part 60, Subpart OOOOa - Standards of Performance for Crude Oil and Natural Gas Facilities for which Construction, Modification or Reconstruction Commenced After September 18, 2015.

The South Oakford Compressor Station was constructed

before this date, and the Subpart is not applicable.

NESHAPS

40 CFR Part 63, Subpart H - National Emission Standards for Organic Hazardous Air Pollutants for Equipment Leaks.

This Subpart has requirements for equipment at

Major Sources of HAPs1, which includes compressors.

However, it is only applicable for sources that have

requirements under a NSPS or MACT standard that

call for this Subpart, which is not the case for any

source at the South Oakford Compressor Station.

Therefore, this Subpart has no requirements for any

source at this facility.

40 CFR Part 63, Subpart HH - National Emission Standards for Hazardous Air Pollutants From Oil and Natural Gas Production Facilities.

This subpart has differing requirements for both

facilities that are a Major Source of HAPs, and

facilities that are area sources. South Oakford is a

Major Source of HAP emissions, but has no

equipment of the types affected by this Subpart.

Also, the South Oakford Station compresses natural

gas that was processed to pipeline quality standards,

prior to entering the station. Therefore, this Subpart

has no applicable requirements for any source at

South Oakford.

(Continued)

1 Maximum potential emissions of the highest individual HAP and combined HAPs are greater than either, 10 TPY, or 25 TPY, respectively.

(Table 5 NESHAPS - Continued)

40 CFR Part 63 Subpart HHH - National Emission Standards for Hazardous Air Pollutants From Natural Gas Transmission and Storage Facilities.

This subpart applies to natural gas storage facilities

that are Major Sources of HAPs, and this is true for

South Oakford. This NESHAPs deals with the glycol

dehydration unit and its associated control device

(flare). BTEX emissions from the flare exhaust must

be lower than the value calculated by Equation 1 in

§40 CFR 63.1275(b)(1)(iii). The Glycol Dehydration

System (Source ID 105) is an existing, small, glycol

dehydration unit, equipped with a flare, and must

have achieved compliance with this Subpart by

October 15, 2015. All pertinent requirements of

Subpart HHH have been included in this renewal

Title V permit, including provisions for monitoring,

recordkeeping and reporting.

40 CFR Part 63, Subpart ZZZZ - National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines.

This MACT was initially promulgated during June 2004

and covers all stationary RICE. It was revised during

both, January 2008 and March 2010, with

requirements for additional classes of engines. The

compressor engines (Source IDs 101 & 102) are

existing, non-emergency, Spark Ignition, two-stroke,

Lean Burn (LB), reciprocating internal combustion

engines (RICE) with a rated capacity greater than 500-

bhp, and located at a Major Source of HAP emissions.

The auxiliary generator engine (Source ID 103) is an

existing, emergency, Spark Ignition, four-stroke, Rich

Burn (RB), reciprocating internal combustion engine

(RICE) with a rated capacity greater than 500-bhp, and

located at a Major Source of HAP emissions, which

does not produce power for sale. 40 CFR

63.6590(b)(3) exempts the compressor engines,

which meet the description in (i), and auxiliary engine

which is covered in (iii).

Therefore, the compressor engines (Source IDs 101 &

102) and the auxiliary generator engine (Source ID

103) have no requirements under Subpart ZZZZ. No

source at South Oakford has any requirements under

this Subpart. (Continued)

(Table 5 NESHAPS - Continued)

40 CFR Part 63, Subpart DDDDD - National Emission Standards for Hazardous Air Pollutants for Major Sources: Industrial, Commercial, and Institutional Boilers and Process Heaters

Some Industrial, Commercial, Institutional (ICI) Boilers

and Process Heaters at major sources of HAPs are

subject to Subpart DDDDD. The natural gas-fired,

3.347 MMBtu/hr Ajax Boiler 1 (Source ID 031) does

have applicable requirements under Subpart DDDDD.

The effective date of this subpart was January 16,

2016, under the subpart. The operator is required to

submit an initial notification, perform a one-time

energy assessment, tune-up the boiler once every five

years, and operate the boiler in a manner to minimize

emissions.

Other Air Programs

40 CFR Part 64 - Compliance Assurance Monitoring (CAM)

Each of the compressor engines (Source IDs 101 &

102) have NOx and VOC emission limits, add-on

controls, and uncontrolled potential emissions of NOx

and VOC greater than the major source amounts.

However, the definition of control device for CAM in

§64.1 Definitions excludes controls that prevent

pollutants from forming, which is the case for both,

the High Energy Ignition and the Clean Burn

Technology on the engines. Therefore, no source at

South Oakford is subject to CAM.

40 CFR Part 98 - Mandatory Greenhouse Gas Reporting

The South Oakford Compressor Station has potential

emissions in excess of 25,000 of CO2e per year. If it

emits greater than this amount, the owner/operator

must report those emissions to EPA.

However, the preamble of the final version of the

GHG MRR, located at 74 Fed Reg 209, pp. 56287-

56288, states that the GHG MRR is not considered an

“applicable requirement” under the Title V Operating

Permit program. Therefore, this Subpart, while an

obligation for the South Oakford, is not considered an

applicable requirement for this TVOP.

Section is applicable.

25 Pa Code § 123.43 (Measuring Techniques) Section is applicable.

25 Pa Code Chapter § 127.441 (Operating permit terms and conditions)

Section is applicable. Emission control, workpractice,

recordkeeping, and reporting restrictions for the

facility were created under the authority of this

section. Also, restrictions relating to emission of SO2

were removed, since they are non-applicable. This is

because no source at the facility is capable of

generating SO2 emissions that approach regulatory

limits.

25 Pa Code Chapter § 129.14 (Open Burning Operations)

Section is applicable. The facility is not in an air basin,

and open burning is allowed, with certain exceptions.

25 Pa Code Chapter § 129.63 (Degreasing Operations)

The facility has two parts washers (Source ID 111)

which have applicable requirements under this

Section.

25 Pa Code 129.91 - 129.95 (Stationary Sources of NOx and VOCs)

Sources at the Station had requirements under

RACT I. However, except for the NOx emission limits

on the emergency generator engine (Source ID 103),

these were superseded by RACT II requirements.

Also, the existing permit contained limits on CO

emissions from the compressor engines, added under

the authority of RACT I (§ 129.91 - 129.95). This

authority does not exist, and these limits were not

carried forward into the proposed permit. (Continued)

(Table 5 Pa. Code - Continued)

25 Pa Code 129.96 - 129.100 (Additional RACT Requirements for Major Sources of NOx and VOCs)

The Station in a Major Source of both NOx and VOCs.

Sources at the Station were constructed before July

20, 2012, and emit NOx and VOC in excess of 1 tpy.

These are the boiler (Source ID 031), compressor

engines (Source IDs 101 & 102), and emergency

generator engine (Source ID 103). The compressor

engines (Source IDs 101 & 102) are subject to a

presumptive, maximum, NOx emission limit of 3

gram/hp-hr and a presumptive, maximum, VOC

emission limit of 1 gram/hp-hr, during normal

operation, under 25 Pa. Code § 129.97(g)(3)(i). The

compressor engines required an alternate compliance

schedule, which is now complete, to meet this limit.

The boiler (Source ID 031) with potential NOx

emissions of less than 5 TPY and potential VOC

emissions of less than 2.7 TPY and the emergency

generator engine (Source ID 103), with the addition of

a fewer than 500-hour annual operation limit are

required to be maintained and operated in

accordance with manufacturer’s specifications and

good operating practices, as presumptive RACT, under

25 Pa. Code § 129.97(c)(1) and (8). These

requirements were added to the proposed permit.

25 Pa Code Chapter 135.3 (Reporting) South Oakford is a Title V facility, and the

owners/operators must submit annual emission

reports.

25 Pa Code Chapter 135.5 (Recordkeeping)

Dominion Energy Transmission, Inc. must fulfill the

following requirements: 1. The permittee shall

maintain comprehensive, accurate records which, at a

minimum, shall include: a. The number of hours per

month that each piece of equipment operated; and b.

The amount of fuel used per month, in each piece of

equipment; 2. The owner/operator shall keep daily

records of all product delivery. 3. These records shall

be kept on site for a period of five years, and be made

available to the Department upon request.

Changes from Existing Operating Permit:

1. The name of the owner has changed from Dominion Transmission, Inc., to Dominion Energy Transmission, Inc. The names of the Responsible Official and Permit Contact have also been updated.

2. The general prohibition against air pollution 25 Pa. Code § 121.7 has been added (Section C, Condition #001, New).

3. Since the natural gas compressors have blow-by emissions of natural gas, the compressors (Source ID 112 for Compressors #1 and #2 and Source ID 113 for Compressors #3 and #4) at the station, were added as sources in the proposed permit.

4. A requirement for weekly surveys of the facility for visible stack emissions, visible fugitive emissions, and malodors, when it is active and manned, and to keep records of these surveys, was added (Section C, Condition #010, New).

5. The applicable requirements of 40 CFR Part 63, Subpart DDDDD were added for the boiler (Section D, Source ID 031, Conditions #002 - #015, New).

6. The applicable requirements for 40 CFR Part 63, Subpart HHH, which have become effective for sources at the facility since the last permit renewal, were added to the permit (Section D, Source ID 105, Conditions #003 - #011, New). Old permit requirements for Subpart HHH were removed (Section C, Conditions #007 and #020 - #024, Old), because the dehydration unit is a small unit, and at the time the previous TVOP was issued, it was exempt from the Subpart.

7. The applicable requirements for RACT II, which have become effective for sources at the facility since the last permit renewal, were added to the permit (Section C, Conditions #026 - #027; Section D, Source ID 031, Condition #001; Section D, Source ID 103, Condition #004; Section E, Source Group G01, Conditions #001 - #002 and #005, New). Clean Burn Technology, a proprietary, very high Air/Fuel ratio combustion process, was added to the compressor engines, and a voluntary limit on the hours of operation of the auxiliary generator engine was added to meet RACT II requirements (Section D, Source ID 103, Condition #002, New). RACT I requirements were removed (Section C, Conditions #008 - #010; Section D, Source ID 031, Conditions #003 - #004; Section D, Source ID 101, Conditions #003 - #007; Section D. Source ID 102, Conditions #003 - #007, Old), except for limits on NOx emission from the aux. generator engine (Section D, Source ID 103, Condition #003, Old), since they were superseded by RACT II. Annual NOx emissions from Source ID 103 were proportioned to its new hourly operation limit (Section D, Source ID 103, Condition #002, New).

8. Limits on CO emissions imposed under RACT I were removed, since the authority to impose these limits did not exist (Section D, Source ID 101, Condition #003 and Section D, Source ID 102, Condition #003, Old).

9. Limits on SO2 emissions have been removed (Section D, Source ID 031, Condition #002; Section D, Source ID 101, Condition #002; Section D, Source ID 102, Condition #002, Old), since emissions are negligible. The natural gas processed and used at the station is of pipeline quality.

10. The language of other conditions in the permit was updated.

Conclusions and Recommendations:

An inspection of South Oakford Compressor Station for a Full Compliance Evaluation was last conducted on April 3, 2016, by Anna Fabrizi, Air Quality Specialist of PA DEP. Ms. Fabrizi determined that the plant met all of the requirements of the existing TVOP. The Compressor Engines (Source IDs 101 and 102) were last tested for NOx, CO, and VOC emissions on December 19, 2017, and found to be in compliance with both, the limits in the current permit and the new limits in the proposed permit. These engines were last tested for formaldehyde on March 13, 2013. The notice of the intent to issue a renewed TVOP, incorporating a Minor Permit Modification with the applicable requirements of RACT II appeared in the Greensburg Tribune-Review on January 18, 19, and 20, 2018. Copies of the proposed permit were sent to Judi W. Fox, Environmental Specialist III, for Dominion, EPA, George Traister, the Department’s Air Quality inspector for the facility, and Tom Norris, Air Quality District Supervisor for the District.

The Dominion Energy Transmission, Inc. has proposed, in this application, to continue to operate a natural gas compressor station in Hempfield Township, Westmoreland County. I recommend the issuance of a five-year Operating Permit for this facility, subject to the conditions in the proposed Title V Operating Permit.
