DESCRIBE OVERALL PROCESS AT THE SITE
The POD61-17 is primarily a natural gas, condensate, and produced water production facility. The inlet production streams flow through high pressure separation equipment,
which separates the high pressure gas, condensate, and produced water streams. The separated high pressure gas and condensate streams flow offsite through pipelines to
another facility.
The separated high pressure produced water streams decrease pressure as they flow into the low pressure separator. The gas stream from the low pressure separator vents to

atmosphere. The skim oil stream from the low pressure separator flows into the skim oil tank, from where the associated vapors vent to atmosphere and skim oil is
periodically loaded into transport trucks and removed from the site. The produced water stream from the low pressure separator flows into one or more of the produced water
tanks, from where the associated vapors vent to atmosphere and produced water is periodically loaded into transport trucks and removed from the site. A blowdown tank
exists to accumulate the expected negligible or very small volumes of condensed liquids associated with various equipment blowdown streams; where the separated skim oil
combines with the trucked skim oil and the separated produced water combines with the trucked produced water.
The expected maximum POD61-17 production rates are listed below.
High pressure gas stream rate: 15 million standard cubic feet per day (MMscfd)
High pressure condensate rate: 3,000,000 barrels per year (BPY)
Skim oil rate: 2,137 BPY
Produced water rate: 988,136 BPY
DESCRIBE PROJECT AND INVOLVED PROCESS
PIONEER has certified the emissions associated with the overall operation of the process equipment at the POD61-17 Facility under Title 30 Texas Administrative Code §
106.352.
The POD61-17 will consist of the following air pollutant emission sources:

One low pressure separator vent (Emission Point No. [EPN] EPN LPSEP);

One skim oil tank (EPN: SOTK);

Up to 3 produced water tanks (EPNS PWTK1 through PWTK3);

One blowdown tank (EPN BDTK);

Skim oil truck loading facilities (EPN LOAD1);

Produced water truck loading facilities (EPN LOAD2); and

Facility fugitive emission components (EPN FUG).
Planned MSS emissions for 12 blowdowns events per year from associated piping/vessels have been reviewed. These authorized MSS emissions are included on the
emissions table.
TECHNICAL SUMMARY - DESCRIBE HOW THE PROJECT MEETS THE RULES
Low Pressure Separator Vent
The separated high pressure produced water streams decrease pressure as they flow into the low pressure separator, from where the separated gas stream vents to atmosphere.
Pioneer used the BR&E process simulation to estimate the maximum expected low pressure separator vent stream composition and rate. In accordance with the 30 TAC
Chapter 101 definition of volatile organic compound (VOC), the calculated mass rates of the propane and heavier hydrocarbon components are summed to determine the
estimated total VOC mass emission rates. The process simulation estimated vent stream hydrogen sulfide (H 2S) content and rate were used to estimate the H2S mass
emission rates.
Skim Oil Tank
Since there is a pressure drop from the low pressure separator to the atmospheric skim oil tank, there will be flash, along with the normal working and breathing loss,
emissions from the tank. Pioneer used the BR&E process simulation to estimate the maximum expected skim oil tank flash vapor stream composition and rate. In
accordance with the 30 TAC Chapter 101 definition of VOC, the calculated mass rates of the propane and heavier hydrocarbon components are summed to determine the
estimated flash vapor total VOC mass emission rates from the tank. The process simulation estimated flash vapor stream H2S content and rate were used to estimate the
flash vapor H2S mass emission rates from the tank.
Pioneer used the BR&E process simulation to estimate the skim oil composition. Since the Environmental Protection Agency (EPA) TANKS 4.0.9d computer program does
not accept the input of components with operating temperature vapor pressures greater than atmospheric pressure, the BR&E estimated percentages of these components
were combined with the BR&E estimated percentages of iso-pentane and normal pentane to determine the skim oil composition to use with the EPA TANKS program. The
estimated skim oil composition, the maximum expected skim oil volume, the currently expected tank attributes, and the EPA TANKS program were used to estimate the
potential working and breathing loss VOC emissions from the tank.
The BR&E process simulation estimated flash VOC emissions were added to the EPA TANKS program estimated working and breathing loss VOC emissions for the
estimated total VOC emissions from the tank. The BR&E process simulation estimated flash H2S emissions were doubled for the estimated total H2S emissions from the
tank, in case there are any working & breathing loss H2S emissions from the tank.
Produced Water Tanks
This registration represents that there may be up to three produced water tanks at this site. Accordingly, the total estimated produced water rate is divided by three for the
produced water rate through each produced water tank. The discussion below is for each produced water tank.
Each Produced Water Tank
Since there is a pressure drop from the low pressure separator to the atmospheric produced water tank, there will be flash, along with the normal working and breathing loss,
emissions from the tank. Pioneer used the BR&E process simulation to estimate the maximum expected produced water tank flash vapor stream composition and rate. In
accordance with the 30 TAC Chapter 101 definition of VOC, the calculated mass rates of the propane and heavier hydrocarbon components are summed to determine the
estimated flash vapor total VOC mass emission rates from the tank. The process simulation estimated flash vapor stream H 2S content and rate were used to estimate the flash
vapor H2S mass emission rates from the tank.
Since the BR&E process simulation estimated essentially no hydrocarbon in the produced water, Pioneer assumed that up to one (1) volume percent (vol%) of the produced
water is skim oil. The estimated produced water composition, the maximum expected produced water volume, the currently expected tank attributes, and the EPA TANKS
program were used to estimate the potential working and breathing loss VOC emissions from the tank.

The BR&E process simulation estimated flash VOC emissions were added to the EPA TANKS program estimated working and breathing loss VOC emissions for the
estimated total VOC emissions from the tank. The BR&E process simulation estimated flash H 2S emissions were doubled for the estimated total H2S emissions from the
tank, in case there are any working & breathing loss H2S emissions from the tank.
Blowdown Tank
Based on the combined volume of the associated piping/vessels and the average operating pressure, the maximum expected volume per maintenance/startup/shutdown (MSS)
blowdown event is determined. There should be no more than one full MSS blowdown event per hour and no more than 12 full MSS blowdown events per year. The
potential hourly and annual MSS vent gas rates are used with a representative gas analysis to determine the speciated mass H2S and VOC emission rates to the atmosphere
from the MSS vents. In accordance with the 30 TAC Chapter 101 definition of "VOC", the mass rates of the propane and heavier hydrocarbon components are summed to
determine the estimated total VOC emission rates.
Truck Loading Facilities
For Each of the Skim Oil and Produced Water Truck Loading Facilities
The uncontrolled truck loading emission rates are estimated using the EP A AP-42 Chapter 5.2.2.1.1 liquid loading equation of (L) = [(12.46) x (S) x (P) x (M)] ÷ (T) and
associated EP A guidance, as well as the TCEQ October 2000 draft document titled "Air Permit Technical Guidance for Chemical Sources: Loading Operations", where:
1.
"L" is the pounds of emissions per 1,000 gallons of liquid loaded;
2.
"S" is the saturation factor - a saturation factor of 0.60 is used since the trucks are generally dedicated service trucks with submerged liquid loading lines;
3.
"P" is the loaded liquid vapor pressure in psia units - the liquid maximum and average vapor pressures from the liquid EPA TANKS program calculation are
respectively used for the hourly and annual loading calculations;
4.
"M" is the molecular weight of the vapors in pounds per pound mole (lbs/lb mole) units - this value is obtained from the liquid EPA TANKS program calculation;
and
5.
"T" is the loaded liquid temperature in degrees Rankine (OR) units - the liquid maximum and average liquid temperatures from the liquid EPA TANKS program
calculation are respectively used for the hourly and annual loading calculations.
The uncontrolled "L" value is multiplied by the estimated maximum number of thousands of gallons of liquid loaded per hour and year to determine the uncontrolled hourly
and annual total emission rates. The vapor weight percents (wt%s) from the liquid EPA TANKS program calculation are multiplied by the total emission rates to determine
the speciated hourly and annual emission rates. In accordance with the 30 TAC Chapter 101 definition of VOC, the calculated mass rates of the propane and heavier
hydrocarbon components are summed to determine the estimated total VOC hourly and annual emission rates. The potential H2S emissions from the truck loading activities
are estimated using the ratio of the determined H2S to total VOC emissions from the associated liquid tank multiplied by the potential total VOC emissions from the truck
loading activities.
Facilities Fugitive Emissions
The utilized fugitive emissions estimation methodologies follow those advocated by the October 2000 draft TCEQ guidance document titled "Air Permit Technical Guidance
for Chemical Sources: Equipment Leak Fugitives". The gas, skim oil, and produced water compositions that are based on the BR&E process simulation, estimated associated
fugitive emission components counts, and the American Petroleum Institute (API) oil and gas production facility empirical fugitive emission factors are used to estimate the
potential fugitive VOC and H2S emissions from the POD61-17. Per instructions from the TCEQ, the estimated hydrocarbon (only) compositions of the liquid stream types
are used with the pertinent API liquid stream type fugitive emission factors to estimate the speciated hydrocarbon fugitive emissions for each liquid stream type. The
estimated propane and heavier hydrocarbon fugitive component emissions are summed for the estimated total VOC fugitive emissions for each stream type. The estimated
total VOC, speciated VOC, and H2S fugitive emissions for each stream type are summed for the estimated fugitive emissions of the same from the POD61-17.
