Denver, CO 80246-1530

Subject: Modification of Existing Condensate Tank BatteryConn Creek Gas Treating Facility, Garfield County, Colorado

Dear Mr. McMillan,

On behatf of OXY USA WTP LP (OXY), ENSR Corporation (ENSR) submits the attached updated Air

Pollutant Emission Notice (APEN), construction permit application and supporting information for a

project to modify two existing condensate tanks and install two new condensate tanks at OXY's Conn

Creek Gas Treating Facility (CCGTF).

The CCGTF (facility) is an existing natural gas processing plant that is operating under several lnitial

Approval construction permits. The facility is a major source for purposes of Colorado's operating

permit (Title V) program. OXY submitted a timely and complete operating permit application to the

bivision and the operating permit is currently in process. The facility is currently a synthetic minor

source (area source) for purposes of National Emission Standards for Hazardous Air Pollutants

(NESHAP) for source categories known as Maximum Available Control Technology (MACT), as

incorporated by reference in AQCC Reg. 8.

Background

OXY owns and operates natural gas production and gathering systems comprising the Grand Valley

Field (Field No. 31290) in Garfield County. The Grand Valley Field includes numerous well sites and

multiple-well pads that produce natural gas. Gas production and gathering operations include three

areas of operation known as: the "Valley" (Cascade Creek and Conn Creek Drainage); the "Mesa";

and the "Logan Wash" areas. Produced liquids (water and hydrocarbon condensate) removed from the

natural gas production stream at each well site or pad by two-phase or three-phase separators may be

stored in one mixed liquid (water and condensate) tank or in separate segregated condensate and

produced water tanks. The liquids are periodically transported by truck to OXY's Cascade Central

Facility ("Water Plant") located in the Valley. As part of a strategy to reduce condensate transportation

costs and to achieve a substantial reduction in volatile organic compound (VOC) and organic

hazardous air pollutant (HAP) emissions from condensate productlon (flashing, working and standing

losses) and truck loading activities, OXY has undertaken a project to centralize condensate handling.

Ultimately, OXY plans to transport rnore produced fluids directly to the CCGTF by pipelines, where the

gas, condensate and water can be separated and the vapors flashed from the condensate can be

controlled.

ENSRMr. Mark McMillanSeptember 19,2008Page2

The CCGTF (AIRS 045/0831) is currently designed to treat and process up to 40 MMscf per day

natural gas gathered from Valley, Mesa and Logan Wash wells. The CCGTF currently operates two

4OO-bbl(each) condensate tanks designated TK-415 and TK-416 (AIRS 045/0831/012). The

condensate tanks currently receive mixed liquids (condensate and water) from the facility's lnlet Slug

Catcher. The hydrocarbons received by the tanks are at elevated pressure and when the condensate

enters the atmospheric tanks, flash vaporization occurs that results in emissions of VOC and organic

HAP compounds. The tanks are operating under terms and conditions of lnitial Approval Permit No.

06GA1232 issued by the Division on October 17,2007. Effective May 1, 2008, the existing tanks

became subject to statewide requirements for condensate tanks set out under Colorado AQCC

Regulation 7 XVll.C. OXY installed a closed vent system designed to route tank vapors to the existing

flare at the facility and since May 2008 the tanks have operated in compliance with AQCC Reg. 7.

Project Description

To accommodate expanding field-wide natural gas and condensate production and to achieve

strategic objectives for centralizing condensate handling operations at the CCGTF, OXY plans to

expand the tank battery at the CCGTF from two tanks to four. OXY will also install a separator/heater

treater and a vapor combustion unit (VCU) to control emissions. ln addition, a produced water tank will

be installed, along with a pump and piping to transport produced water to the Water Plant. Stabilized

condensate product will be loaded out by truck.

As illustrated in the attached simplified process flow diagram and projected site diagram, one new

46g-bbl "separator Feed Tank" (TK-5235) and one new 400-bbl condensate storage tank (TK-417) will

be installed. The two existing condensate tanks (TK-415 and TK-416) will be converted from flashing

tanks to stabilized condensate storage tanks. ln addition, one new 400-bbl produced water tank will be

installed (T-5310).

The new Separator Feed Tank will receive mixed liqurids from the facility's lnlet Slug Catcher, which

receives field gas and produced liquids from the Grand Valley Gathering Systems. The condensate

received by Separator Feed Tank will be at lnlet Slug Catcher pressure conditions and will contain

solution gas, so flash emissions will occur from the Separator Feed Tank when the pressure is

reduced to atmospheric. All four hydrocarbon tanks and the three-phase separator/heater treater will

be connected to the new VCU(s) by a closed vent system. Mixed liquids from the Separator Feed

Tank will be routed to a new three-phase separator and heater treater to separate water, condensate

and any gas still in solution. Water will be routed from the separator/heater treater to the new 400-bbl

produced water surge tank. Stabilized condensate (no solution gas) will be routed from the

separator/heater treater to three condensate storage tanks (TK-41514161417). The condensate

received by the three storage tanks will be at near-atmospheric conditions, so no flash emission will

occur. Working and standing losses may however occur from vapor displacement during filling

operations and from diurnal fluctuations in ambient temperature. Condensate will be piped to a new

truck loading station located just east of the CCGTF. Water will be pumped from the Water Surge

Tank (T-5310) to the Water Plant.

The VCU will be an enclosed combustor that will achieve a 98 percent reduction in VOCs. The

make/model of the unit is yet to be determined, but the VCU and the closed vent system will conform

to AQCC Reg. 7. The facility may install more than one VCU, as necessary to accommodate vapor

throughput.

ENSRMr. Mark McMillanSeptember 19,2008Page 3

The modified tank battery at the CCGTF will include:

. three 4oo-bbl (each) condensate storage tanks: one new tank (TK-417) and two existing tanks

(TK-415 and TK-416);

r one new400-bbl Separator Feed Tank (TK-5235)

. one Relief Knockout vessel (V-51 15)

! one new three-phase separator (V-5240) and one new natural gas-fired heater treater (V-

5245)

r one or more natural gas-fired vapor combustion units (VCU-51 16)

r one new Water Surge Tank (T-5310)

. one new separator feed pump (P-5234)

r one new water pump (P-5311) and piping to the Water Plant

t one new Condensate Unloading Pump (P-5234)

r new truck loading station

The current lnitial Approval Permit No. 06GA1232, which was issued prior to promulgation of

statewide requirements for condensate tanks set out in AQCC Reg. 7, includes terms and conditions

limiting condensate throughput to 7 300 bbls per rolling 12-months and VOC emissions to 55.3 tonsper rolling 12-months. The attached APEN requests a substantial increase in condensate throughput

irom the iurrent permit limit, but with the 98 percent reduction that will be achieved by the VCU(s),

VOC emissions will decrease substantially from the current permit limitation. ln addition, as discussed

above, field-wide VOC emissions from the well sites/pads will decrease as a result of the centralized

condensate handling strategy and the reduction in emissions at the well sites from flashing and truck

loading. Also, the reduced truck traffic will result in a reduction in vehicle miles traveled on unpaved

roads, which will reduce PM10 emissions and truck exhaust emissions.

The tanks are not affected by federal New Source Performance Standards (NSPS) set out at 40 CFRpart 60 Subpart Kb and incorporated by AQCC Reg. 6 because the tanks each have a design capacity

less than or equal to 1,589.874 m' 4+0,000 gallons) and they are each used for petroleum or

condensate stored, processed, or treated prior to custody transfer [40 CFR 560.1 1 0b(dx4)].

The tanks are not "storage vessel with the potential for flash emissions" as defined in the Oil and

Natural Gas Production MACT rule set out at 40 CFR Part 63 Subpart HH. The oil and natural gas

production MACT regulates "storage vessel with the potential for flash emissions" located at major

sources of HAP. Subpart HH defines "storage vessel with the potential for flash emissions" to mean

(emphasis added): "any storage vessel that contains a hydrocarbon liquid with a stock tank GOR

equal to or greater than 0.31 cubic meters per liter [1,750 cflbbl] and an API gravity equal to or greater

than 40 degiees and an actual annual average hydrocarbon liquid throughput equal to or greater than

79,SOO titerl per day [500 BOPD]. The Separator Feed Tank will have flash emissions, as discussed

above, and the API gravity of the condensate will exceed 40, but the actual annual average and the

requested allowable annual total condensate production rate for the tank battery, requested in the

attached APEN (96,360 bbls/year and 264 BOPD) will be less than the 500 BOPD threshold. As a

consequence, the condensate tanks would not be affected facilities under Subpart HH even if the

facility were to become a major source.

Air Pollution Control Division

Coloedo Dcrmrunenrof Public flerkh*od Ervironnr*nrOperating and Maintenance Plan Template for

Condensate and Mixed Liquid Storage TanksVer. September 10,2008

The Air Pollution Control Division (Division) developed this Operating and Maintenance Plan (O&M Plan) for condensate andmixed liquid storage tanks permitted at synthetic minor facilities in the State of Colorado. An O&M plan shall be submittedwith the permit application. One O&M Plan may be used for multiple tanks at one facility if each are controlled and monitoredin the same manner. If the O&M Plan template is completed correctly, the Division will approve the O&M plan and aconstruction permit will be issued with the requirement to follow the O&M Plan as submitted. If the template is not completedcorrectly, the Division will work with the facility to make corrections. Once a construction permit is issued, the facilityoperator must comply with the requirements of the O&M Plan upon commencement of operation. Operators are not requiredto use this template. Independent case specific O&M Plans may be developed and submitted for approval with the pirmitapplication. However, the Division encourages the use of this template to expedite the permit application approval p.o..ir.

Submittal Date: September 21, 2008

Section 1 - Source ldentification

For new permits some of this information (i.e. Facility AIRS ID, Facility Equipment ID, permit Number, and AIRS point ID)may not be known at the time of application. Please only fill out those fields that are known and leave the others blank.

Company Name:Facility Name:

OXY USA WTP LP Facility Location: S32 T65 R97W, Garfield CountyConn Creek Gas TreatingFacility

Facilily AIRS ID (for existing facilities) 045/0831

' Tank types include condensate (C) and mixed liquid (ML)

Section 2 - Maintenance Schedules

Check one of the following:

Facility shall follow manufacturer recommendations for the operation and maintenance of equipment and controldevices. These schedules and practices, as well as any maintenance records showing compliinCe with theserecommendations, shall be made available to the Division upon request.

Facility shall follow individually developed maintenance practices and schedules forthe operation and maintenance ofequipment and control devices. These schedules and practices, as well as any maintenancsrecords showing compliancewith these recommendations, shall be made available to the division upon request and should be consisteniwith goodair pollution control practices for minimizing emissions as defined in the New Source Performance Standard (NSpS)general conditions.

Section 3 - Monthly Emission Modelins or Calculations

The following box must be checked for o&M plan to be considered complete.

The source will calculate emissions based on the methods and emission factors provided in the permit application andX approved by the division, as reflected in the construction permit. Please see the operation and maintenance plan

guidance document for further details and examples of emission calculations.

Section 4 - General Monitoring Reouirements

All condensate collection, storage, processing and handling operations, regardless ofsize, shall be designed, operated andmaintained to minimize leakage of volatile organic compounds to the atmosphere to the maximum extent practicable.

Table I below details the schedule on which the source must monitor each of the listed operating parameters depending on therequested permitted emissions at the facility. Check the appropriate box based on the faiility widi permitted VbC emissions.

Table 2 outlines condensate and mixed liquid throughput monitoring methods. The source must chose one primary monitoringmethod and, optionally, may chose up to two backup methods. CheCk each box that applies.

Section 5 - Emission Control or Recycling Equipment Monitoring Requirements

If a control device is used then leakage of VOCs to the atmosphere must be minimized as follows:

o Thiefhatch seals shall be inspected for integrity annually and replaced as necessary;o Thiefhatch covers shall be weighted and properly seated;o Pressure reliefvalves (PRV) shall be inspected annually for proper operation and replaced as necessary;o PRVs shall be set to release at a pressure that will ensure flashing, working and breathing losses (as applicable) are

routed to the control device under normal operating conditions;t Annual inspections shall be documented with an indication of status, a description of any problems found, and their

resolution.

Dear Mr. Vaughan,

This letter described the results of Hankard Environmental's analysis of noise from Oxy's ConnCreek Compressor Station Expansion Projec! which is located in Garfielcl County, Colorado.Noise levels from the existing Conn Creek Compressor Station were measured, and this datawas used to predict the noise levels that will exist when the expanded station is operational.The noise levels predicted from the combined operation of the;xisting and expanded facilitiesare below the limits promulgated in applicable Garfield County and State of Coloracloregulations. The following describes the project site, applicable noise regulations, the results ofour noise level measurements, and the noise levels we predict from the Combined operation ofthe existing and proposed compressor stations.

PROJECT AND SITE DESCRIPTIONThe proposed Conn Creek Compressor Station Expansion Project is located in Garfield County,approximately 11 miles north of De Beque, Colorado. The existing and expansion compressorstation sites are located in a deep valley off of Conn Creek Road, as shown in Figure 1. The landto the north of the site is owned by Oxy USA Inc., out to a distance of approximit"ty fir" miles,Two-thousand foot high ridges are located to the east and west. The land over the eastern ridgeis owned by the Puckett Land Company, and is currently being explored for gas development-potential. The land over the western ride is owned by the Shell Frontier Oil and Gas Company,and is also being explored for gas development potential. The land to the south of the site isowned by the Bureau of Land Management and the Savage Limited Partnership.

A three-dimensional map of the site is show in Figure 2. The primary noise generatingcomponents of the existing station include the Generator Building and the CompressorBuilding. The Generator Building contains three Caterpillar 3512 Generator Seti with exteriorcooling towers. Only two of these engines run at any one time per on site management. Theexisting Compressor Building houses five Caterpillar 3516 units with exterior

"ooling towers.

The primary noise source at the expansion compressor station will be a Compressorbuildingthat will house two Caterpillar 3616 units with exterior cooling units.

APPLICABLE REGU LATIONSSecLion 5'03.08(1) of the Garfield County Zontngand Subdivision Regulations (lndtLstrialPerfotmance Standards for Conditional and Special Uses) states that the "Volume of sounclgenerated shall comply with the standards set forth in the Colorado Revised Statutes at the timeany new application is made' (A. 93-061)". This refers to the Colorado Revised Statutes (C.R. S.)525-1_2-101et seq. noise regulation. A second noise regulation that is applicable to this pioject isthe Colorado Oil and Gas Conservation Commissio.,'r ICOCCc) Rule

^SbZ lupaated November

2006). The noise limits contained in these two regulations are identical, ani their maximumpermissible noise levels are shown in Table 1.

The noise limits shown in Table 1. vary depending on time of day and surrounding land use.Thepermit being applied for will allow 24 hour per clay operation, thus the maximum noiselevel will be defined by the nighttime (quietest) ii*it fo, each land use zone. COGCC Rule g02states that "In remote locations, where there is no reasonably proximate occupied strucfure ordesignated outside activity area, the light industrial standard may be applicalle,,. There are nooccupied_structures (residences) located within at least two miles of tne p.oposed project. Interms of land use, almost all of the land surrounding the site is being developed for gus

NOISE MEASUREMENTSNoise Ievels from the existing operations (compressor station ancl generators) were measureclon August 26,2008 at the eleven locations around the site shown ir', Figrr" 3. A Larson DavisModel824 Sound Level Meter (ANSI Type 1) was usecl for all measurements. The meter wascalibrated within the past year by the manufacturer, and field calibrations were also conducted.All of the noise level measurements were taken with the microphone mounted five feet abovethe ground on a tripod, and with the microphone fitted with a iin.1r.r"".r. The equivalentsound level (L"q) for each location was measured for one to five minutes and paused whenvehicular or other non-facility noise was present. The measured noise levels are shown inFigure 3 (Luq, dBA). The levels range from 5g to 23 dBA.

During the noise level measurements the existing compressor station was operatin g atgO% ofcapacity (typical), two_ of the three generator engines were running (standard proc&ure), andall garage doors and doorways were completely open (worst-case). fn" winds were blowingbetween 3 to 10 miles per hour from the south. Ali of the noise measurements were takendownwind or cross-wind from the site. Overall, these measurements represent "worst-case"(loudest) conditions. The measured noise levels, which include one-third octave band soundlevels, were used to calculate the sound power level for the existing generator building, existingcompressor station building, and future compressor station building(discussed. belowJ.

NOISE ANALYSIS RESULTSNoise levels from the combined operation of the existing and expansion compressor stations atConn Creek were predicted using an acoustical computer model (SoundPlan v6.5). SoundPlanis an internationally recognized sound propagation software model which utilizes iSO-9613outdoor sound propagation algorithms. Parameters input into this model included terrain type,terrain elevation, the locations of buildings that act as barriers, and the sound power level of themajor compressor station noise sources (existing generator building, existing compressor stationbuilding, and proposed compressor station building). The terrain information wis derivedfrom 15 meter elevation contours. The locations of buildings were approximated from acombination of digital aerial mapping and design drawings of the proposed compressor station.The sound Power levels for the existing generator building and existing .o*pr"sio. stationbuilding were calculated from the measurements conducted for this project (described above).This same sound Power level was assumed for the proposed compressor station, as the numberand type of equipment is identical.

First a noise model of the existing compressor station was generated and usecl to predict noiselevels at the measurement locations. The model was validated by comparing meaiured andpredicted results. The measured and predicted noise levels agreed within approximately t3dBA for locations within 500 feet of the existing station. This is within the expectecl accuracy ofthe model.

Next, the proposed compressor stafion was added to the noise model and the model was usedto predict how noise will propagate from the compressor station toward adjacent properties.Figure 4 shows the results of this analysis in the form of noise level contours overliid onto anaerial photograph of the project site. From the figure it can be seen that 65 clBA (project limit) isnot exceeded outside of Oxy USA's property. Note that these noise level predictions assumethat all of the doors in the generator building and both compressor buildings are completelyopen. Thus, lower levels would be expected with all or some doors closecl.

In summary, noise levels from the combined operation of the existing Conn Creek CompressorStation and the Conn Creek Compressor Station Expansion Project are preclicted to be lowerthan the 65 dBA limit specified by the State of Colorado when measured at any point along theproject's property boundary.
