1. Introduction
Background and Purpose of This Permit Amendment
MarkWest Javelina Company, LLC (MarkWest) owns and operates the Javelina Gas Processing
Facility, located at 5438 Union Street in Nueces County, Texas. The Javelina Gas Processing
Facility is authorized by New Source Review (NSR) Permit Number 19296. On June 13, 2014,
the TCEQ received an application to renew Permit Number 19296. On January 5, 2018,
MarkWest also submitted a permit amendment application to authorize emission increases that
were represented in the June 2014 renewal application and address additional items
subsequently identified by the TCEQ. The permit renewal and this permit amendment
application are pending issuance by the TCEQ.
MarkWest has recently conducted a retagging of its fugitive equipment leak components.
MarkWest has also conducted a technical evaluation of its maintenance, startup, and shutdown
(MSS) activities. This permit amendment application reflects corrections to the fugitive
emissions, MSS emissions, and other updates to appropriately represent the existing facility
operations. MarkWest requests to replace the January 2018 amendment application with this
amendment application.
The Javelina Gas Processing Facility was designed to process 140,000,000 standard cubic feet
per day of inlet gas and is not requesting any production increases. Please note that this
amendment application is not for an increase in operation or production, but rather to update
fugitive equipment leak representations, include additional MSS activities, and correct other
representations.
Tables A and B contain an annual and hourly summary of the current permit limits, proposed
permit limits, and changes in emissions for this proposed amendment, respectively. The
Javelina Gas Processing Facility is not a major source for criteria pollutants, and the proposed
changes do not trigger major new source review permitting. Therefore, Greenhouse Gas (GHG)
emissions are not required to be included in the permit application. MarkWest complies with the
applicable GHG reporting requirements under 40 Code of Federal Regulations Part 98. Boiler
representations remain unchanged since the 2004 permit renewal.

4. Process Description
Javelina Gas Processing Facility is unique and functions as a reuse/recovery operation that
ultimately provides waste minimization and emissions reduction in the area by processing
refinery off-gas from several facilities in the Corpus Christi area. Excess off-gas at the refineries,
if not beneficially used, would have to be flared. The Javelina facility processes refineries off-
gas, recovers various useful products, and the residue gas is returned to the refineries as clean
fuel gas.
Refinery off-gases from Corpus Christi area refineries are delivered via pipeline to the Javelina
Gas Processing Facility, and the gases are further processed. MarkWest produces LPG, which
is primarily sent off site via pipeline. This section contains a process flow diagram, which
outlines the primary equipment at the site. This application includes an update of the piping
components such as valves, connectors, and compressors, based on a recent retagging of
equipment.
Additionally, routine maintenance occurs at the Javelina Gas Processing Facility to ensure
equipment is operating properly and control devices are operating properly to minimize
emissions and ensure compliance with permitted limits. MarkWest authorized many of its MSS
activities in the December 2014 amendment to Permit Number 19296; however, MarkWest has
since identified additional activities to authorize in its permit. Thus, additional activities and
routine maintenance on additional process equipment is represented in this amendment
application. Process equipment and other routine maintenance that may occur at MarkWest
include, but are not limited to, the following examples:
• Maintenance/catalyst change/cleaning of process vessels and associated piping and
other equipment and activities, such as:
o Acetylene unit
o Butylene conversion unit
o Ethylene and propane refrigeration systems
o C4 reactor
o C5 HDS unit
o Demethanizer unit
o Deethanizer/C2 splitter
4-2
o Depropanizer/C3 splitter
o E/E treaters
o P/P treaters
o Expander
o Mercury guard bed
o Gas compressor areas
o Scrubbers and separators
o Dehy units
o Meter provings
o Maintenance of all pumps and valves
o Sulfurox unit and incinerator
o Amine regeneration and tail gas treating areas
o Various filters
o PSA unit
o Exchangers and coolers
o Cryo Unit
o VRU
o Fuel gas system
o Flare pilot
o Heaters
o Wastewater and storm water system maintenance
o Filter maintenance
o Prover trailer and meters
o Pipeline clearing and rebalancing, and
o Pig launching for maintenance.
Further, many routine MSS activities are controlled in MarkWest’s flare, which has continuous
monitoring. MarkWest is submitting this amendment application to update permitted emission
limits to more accurately represent reasonable worst-case flare emissions. In addition,
MarkWest’s permit currently authorizes 876 hours of sulfur recovery incinerator bypass. During
these periods, the waste gases are routed to the flare, and MarkWest is representing these
flaring emissions. Markwest’s current permit also includes off-gas flaring from the neighboring
Air Products facility. MarkWest proposes to simplify the permit structure outlined in the
Maximum Allowable Emissions Rate Table, which provides for four separate emission limits for
4-3
the flare. Currently, the permit contains separate emission limits for routine MarkWest
emissions, MSS emissions from activities conducted at MarkWest, Air Products emissions, and
MarkWest startup and turnaround emissions. MarkWest contends that the four emission limits
for the EPN presents unique recordkeeping challenges, since the four limits apply to the same
EPN, and multiple limits may apply simultaneously. MarkWest, therefore, requests a simplified
permit structure, the specifics of which are outlined in Sections 6 and Appendix A.
Prior to conducting maintenance on a facility such as a process vessel, it must be cleared,
purged, and degassed. MarkWest previously permitted vessel purging, which is controlled by
the site’s flare. In accordance with TCEQ control requirements for MSS, vessel purging and
degassing is controlled to 10% Lower Explosive Limit (LEL). The residual VOCs that are
contained in the vessel may be vented to atmosphere, and MarkWest identified that these VOC
emissions are not currently included in its air permit. MarkWest is amending its permit to
authorize the degassing emissions and ensure that its permit comprehensively includes the
appropriate emissions associated with routine MSS. Markwest conducted a comprehensive
retag effort for fugitive components throughout the facility. This permit amendment application
also includes the updated component counts to appropriately represent as-built operation and
its associated emissions.
5-1
5. Process Emissions This section describes the emission calculation methods associated with this permit amendment
application.
Flare Emissions
This amendment application includes updated flare emission calculations. The emissions are
based on historical flare CEMs data from 2014 through 2017, with a 15% safety factor included.
Site-wide plant startup/shutdown/turnaround (TAR) emissions were based on a full shutdown
scenario, with three nitrogen purges to 10% LEL. Flare data from shutdown events occurring in
2016 were also evaluated, which included a shutdown for Hurricane Harvey and two additional,
smaller-scaled shutdown/maintenance events, with a 15% safety factor. The emissions for TAR
are established with the higher of the TAR full shutdown calculation, 2016 flare data, or permit
limits established in the current permit. The overall flare limits are proposed by summing all
potential events on an annual basis. Hourly limits were established by taking the higher of
hourly routine emissions that may occur or plantwide MSS emissions.
Fugitive Emissions
Fugitive emission rates of VOC from the piping components and ancillary equipment are
estimated using the methods outlined in the TCEQ’s Air Permit Technical Guidance for
Chemical Sources: Fugitive Guidance, December 2017. Each fugitive component is classified
first by equipment type (valve, pump, connector, etc.) and then by material type (gas/vapor, light
liquid, heavy liquid). An uncontrolled hourly VOC emission rate is obtained by multiplying the
number of fugitive components of a particular equipment/material type by the appropriate
SOCMI emission factor. To obtain controlled fugitive emission rates, the uncontrolled rates are
multiplied by a control factor. MarkWest historically employed the TCEQ’s 28 M LDAR program
and is currently using EPA’s approved Alternate Work Practice (AWP) that enhances the LDAR
program using Optical Gas Imaging (OGI). EPA has incorporated OGI in the promulgated
regulations (e.g. 40 Code of Federal Regulations Part 60, Subparts OOOO and OOOOa). OGI
can detect leaks for VOC and Greenhouse gases. MarkWest uses OGI on a bi-monthly basis,
and any leak detected is then followed by Method 21 monitoring to confirm and take corrective
actions for any VOC leaks. This practice includes difficult to monitor components. Markwest’s
LDAR contractor is working with TCEQ for approval of OGI as an AWP. The emissions in this
application represent the implementation of TCEQ’s 28 VHP LDAR program. In addition,
5-2
MarkWest monitors and identifies leaks for repair for connectors on an annual basis. As such,
28 CNTA control credits are applied to the connectors and 28 VHP control credits are applied to
the other fugitive components. Stream speciation is applied to determine the hourly emissions.
Annual fugitive emission calculations are based on 8,760 hours of service. Pumps with dual
tandem seals with vapor barrier vents to flare that are alarmed are exempt from monitoring and
100% reduction credit is taken. Inlet Gas Compressor D rod packings are vented to the flare,
and a 100% reduction credit is also taken on those components. Additionally, the refrigerant
compressors are contained in a closed loop system with no emissions to the atmosphere, and
100% credit is taken on those components. The Inlet Gas Compressors’ 1st stage and 2nd stage
rod packing are routed to two separate pipe vents, IGC Vent 1 and IGC Vent 2. Over time, the
rod packings have potential to leak. MarkWest has added these two EPNs in the permit
amendment application. The emission are estimated based on flow rate measured for the
Greenhouse gas (GHG) reporting and using expected worst case short-term and average
compositions for hourly and annual calculations.
Process Heater Emissions
Emissions of PM10 and VOC from the Molecular Sieve and Regeneration Heaters are based on
AP-42 emission factors. CO and NOX emissions from the Butylene Converter are also based on
AP-42. SO2 emissions are based on combustion of gas containing 0.05 grains sulfur per dry
standard cubic feet. Assuming all of the sulfur is converted to SO2 during combustion, 1 lb-
mole of sulfur in the fuel yields 1 lb-mole of SO2 out of the stack. The molar flow rate of SO2 out
of the stack is then multiplied by the molecular weight of SO2 to obtain the hourly emission
rates. Annual emission rates are based on the average heat input and 8,760 hours per year.
Boiler Emissions
Boiler emissions remain as represented in the current permit and Maximum Allowable Emission
Rate Table (MAERT).
Cooling Tower Emissions
The cooling tower is an existing facility, and PM10 and PM2.5 emissions are represented in the
application per TCEQ guidance. Historically, TCEQ was not including PM emissions from the
cooling towers. The PM10 and PM2.5 emissions are estimated using the methodology provided in
5-3
the Reisman and Frisbie paper entitled “Calculating Realistic PM10 Emissions from Cooling
Towers.” Detailed calculations are provided in Appendix A.
The recirculation rate and the current BACT limit of 0.08 ppmw are the basis for the hourly and
annual emissions of VOC. Markwest is not requesting any change from the current MAERT.
Please note, that currently the cooling tower has a VOC leak. As discussed in prior
conversations with TCEQ, Air Permit Division, the corrective action will require a plant wide
shutdown, which will result in emissions more than current cooling tower emissions. Therefore,
the cooling tower is under a delay of repair. The cooling water exchanger system upstream of
the cooling tower was sampled to identify potential leak locations. MarkWest has already
purchased four (4) replacement exchangers which are being stored on site. Two (2) additional
exchangers will be replaced or repaired. All exchanger work will be addressed during the next
scheduled turnaround. Meanwhile, MarkWest is continuing to sample the cooling tower on a
monthly basis.
Sulfur Recovery Incinerator Emissions
Vendor-specific data and AP-42 factors are used to estimate the emissions from the sulfur
recovery incinerator. Detailed calculations are provided in Appendix A.
6-1
6. Best Available Control Technology Evaluation A BACT analysis is required since this permitting application includes an amendment. No
modifications have been proposed, and this permit application is for all existing equipment and
facilities. This section contains a summary of the BACT analysis. BACT is established
pursuant to the TCEQ’s three-tiered BACT review. Tier I BACT consists of the level of control
technology currently accepted and established as BACT through permit reviews for that type of
facility in the same industry. Tier II BACT consists of the level of control technology currently
accepted as BACT in recent permits for similar air emissions streams in a different industry.
Tier III BACT is a detailed technical and quantitative economic analysis of all emission reduction
options available for the process under review. For the types of facilities covered by this
application, current Tier I BACT can be identified by examining current TCEQ air permit
technical guidance documents.
Flare The flare was designed to meet the standards in 40 Code of Federal Regulations §60.18.
Further, MarkWest monitors the flow of vent gas to the flare, BTU content, ammonia, and
monitors H2S and hydrocarbons with a GC. A 98% control efficiency for all hydrocarbons is
conservatively represented. Therefore, BACT is met.
Fugitives
Markwest, through consultant, is working with TCEQ for approval of Optical Gas Imaging (OGI)
as an Alternative Work Practice (AWP) for the Texas LDAR program. Upon issuance of this
amendment, MarkWest will employ 28 VHP, which is current TCEQ BACT. Additionally,
MarkWest will conduct annual monitoring of connectors.
Process Heaters
The adjustments in the emissions calculations results in an increase in VOC emissions for the
Molecular Sieve Heater and Regeneration Heater. Following good combustion practices will
minimize VOC and represents BACT for the heaters. Small increases are also represented for
the Butylene Converter. This heater is less than 4 MMBtu/hr, and TCEQ prescribes BACT for
heaters greater than 40 MMBtu/hr.
6-2
Sulfur Recovery Incinerator
The permit amendment includes slight emissions increases for the sulfur recovery incinerator. It
does not appear that the last permit renewal properly represented the facility’s heater duty, and
the emission calculations have been corrected. The minimum inlet gas flowrate remains
unchanged, and the facility is not increasing production. The incinerator continues to represent
99% efficiency, which reflects BACT given the facility’s age.
MSS
Equipment is purged to 10% LEL, and gas streams resulting from MSS activities and equipment
purging are controlled by the flare. Current TCEQ guidelines indicate that BACT for MSS is the
same as current BACT requirements for flares. Since BACT for flares is met, BACT for MSS is
also met.
7-1
7. Federal NSR Applicability The Javelina Gas Processing Facility is located in Nueces County, which is an attainment or
unclassified area for all pollutants. Therefore, Nonattainment NSR permitting does not apply.
MarkWest has calculated the emission increases for all affected sources. The site is an existing
minor source, and PSD would be required if the project increase meets major source
thresholds. The requested emission rates from all affected sources are below major source
thresholds, therefore PSD review is not required.

Notes:1. Emission rates based on continuous flare monitoring data.2. Routine MSS totals are summed to determine annual emissions and the highest four are summed to determine reasonable worst‐case short‐term emissions.3. Since the emission rates are based on monitoring data, a 15% contingency is added to account for MSS activities that may not have occurred during the four‐year period on which this analysis is based, or at the highest potential maximum rate.4. Established in the permit's current maximum emission rates table.5. Routine MSS totals with 15% contingency, Normal Operations totals, flaring of off‐spec gas, and Air Products flaring emissions are summed to establish total routine maximum emissions.6. Established plantwide turnaround totals were evaluated with 2017 events, which included shutdown/startup for Hurrican Harvey and two other planned events. A full plant shutdown scenario was also considered (see Table A‐12). Currently established permit limits were also considered, and a 15% contingency was applied as necessary. The highest values are used to establish the limits.7. TAR emissions are tracked separately from routine flaring emissions and, as such, the highest of the routine maximum emissions and TAR emissions are taken to establish the flare permit limits.

1. The ethylene concentration in the inlet gas stream is less than 11%; therefore, SOCMI Without Ethylene Factors were used.2. Relief valves are routed to the flare ; therefore, 100% control efficiency is applied.3. Pumps packing are controlled with dual seals, leakage routed to seal pot then flare.4 IG Compressor D emissions are routed to flare. IG compressors A, B, and C rod packing streams are manifolded and emitted through two stacks, with remaining emissions routed to the flare. Refrigerant compressors are in a closed-loop system.
