RE: Enerplus Resources (USA) Corporation Application for New Construction

Oak/Spruce Facility

To Whom It May Concern;

Enclosed please find the application for new construction for the Enerplus Resources (U SA) Corporation Oak/Spruce

facility. Included in the application for new construction is a synthetic minor limit request for the facility requesting

federally-enforceabl e limitations on the facility’s potential to emit.

An environmental assessment, including an evaluation of endangered species and an archeological survey, has been

completed for this facility and the final report has been su bmitted to the attention of Mr. Mark Herman of the United

States Department of the Interior, Bureau of Indian Affairs in the Great Plains Region Office located in Aberdeen, South

Dakota.

As requested, the application contains backup calculations for the various input parameters used in calculating the

potential to emit for the facility; howe ver, the finalized summary developed by the North Dakota Bakken Task Force for

the calculation the applicable tank flash emission factor (97. 91 standard cubic feet per barrel) has not been included in

this application at this time as the Task Force has not re leased their final document. Upon release, Enerplus Resources

(USA) Corporation will make available to the EP A the finalized summary under separate cover.

If you should have any questions or concerns, please don’t hesitate to contact the undersigned.

Respectfully,

Tony Lucero

## Facility Process Description

Generally, a crude oil reservoir contains not only the oil itself, but saline water and also a dissolved form of natural gas

due to the high pressures of the underground reservoir. Because fluids from a reservoir are under a higher pressure

below ground than at the ground surface, recovery of fluids is initially driven by rock and fluid expansion from reservoir

conditions to surface conditions. After time this pressure source becomes depleted and the well will no longer flow to

surface and an artificial lift, usually in the form of a pump, must be installed to continue production.

Fluids produced at the wellhead(s) are transferred via an underground flowline(s) to various processing units utilized to

separate the fluids into three phases; oil, natural gas, and water. The separator and heater/treater processing units

separate the fluids into the three different process streams. The different fluid densities are used to separate the fluids

and heat is used to make the process more efficient. Descriptions of the elements involved in the crude oil recovery

process are described below:

High

Ͳ Pressure Natural Gas

Dissolved natural gas entrained in the wellhead fluids evolves out of solution as the pressure of the fluid decreases.

Additionally, as the wellhead fluid(s) is heated, the natural gas components off

Ͳ gas more readily than the heavier oil

and water counterparts. Recovered natural gas is either used as fuel for onsite equipment or transferred to the

natural gas sales line for conveyance to a gas plant for sale.

Crude Oil

Recovered crude oil is separated from the saline water component of the recovered fluids in the heater/treater

processing units and is transferred via underground flowlines to aboveground oil storage tanks. Crude oil is

temporarily stored in these on

Ͳ site containers prior to being transferred to the lease automatic custody transfer

(LACT) unit for conveyance to a refining process plant.

Saline Water

Recovered saline water is similarly separated from the crude oil component of the recovered fluids in

heater/treater processing units and is transferred via an underground flowline(s) to an aboveground storage

tank(s). Recovered water is temporarily stored on

Ͳ site prior to being loaded into tanker trucks for transport and

disposal.

Low

Ͳ Pressure Natural Gas

In addition to the natural gas recovered from the wellhead fluids as described above, natural gas is also collected

and recovered from off

Ͳ gassing that occurs from the crude oil stored in the on

Ͳ site oil storage tanks. This natural

gas is collected in what is called a vent line from the oil storage tanks and water storage tank(s) at the facility. This

additional, low

Ͳ pressure, natural gas is routed to an enclosed combustion device capable of a minimum destruction

removal efficiency of 98%.

Recycle Pump Process

This facility also has a recycle pump(s) that is used to return fluid from the above ground oil and water storage

tanks to the heater/treater in the event the oil or water does not meet quality standards and needs additional

processing.

Upset Conditions

Although a sales line for both the natural gas and crude oil are present at the facility, a condition known as an

“upset” may occur in which the produced and recoverable natural gas cannot be transferred to the natural gas

sales line. In these instances, the high

Ͳ pressure natural gas will be routed to a ground pit flare capable of 90%

destruction removal efficiency.Enerplus Resources (USA) Corporation

The heater treater burner fuel consumption was calculated using the equipment capacity of 500,000 British thermal

units (Btu), with an assumption of continuous operation using natural gas fuel and an average gross heating value of

approximately 1,020 British thermal units per standard cubic foot (Btu/scf) (AP

Ͳ 42, Vol. I, Ch 1.4: Natural Gas

Combustion).

The recycle pump fuel consumption was calculated using the actual fuel tank size of 1.6 gallons with an assumed use of

one tank per month. The generator(s) fuel consumption was calculated by converting the generator size in kilowatts (kW) into Btu per hour,

with an assumption of continuous operation using natural gas fuel and an average gross heating value of approximately

1,020 Btu/scf (AP

Ͳ 42, Vol. I, Ch 1.4: Natural Gas Combustion).

Engines listed above will meet the applicable emission standards in accordance with published regulatory standards. EPA

emission standard certification(s) of conformity and emission warranties for proposed engines are included in

## Decline Factor Supporting Documentation

### The Basis for the 0.6 Factor and How it Relates to 80% Decline in Production for the First Year

The first year daily production rates are represented by the jagged line in BOX 1

.  The area under the line

represents the total actual production volume for the first year.  It is difficult to calculate the total volume

under the jagged line so it is smoothed out in BOX 2 using statistical methods.

BOX 1  BOX 2 

BOX 3  BOX 4 

The smoothed curve is straightened out in BOX 3

, and then leveled out in BOX 4

. Now the production for the

first year is represented by the area under the line in BOX 4 which is easily calculated. Production curves from

a large sampling of wells indicate the average well declines by 80% during the first year. That 80% decline is

represented by the level line in BOX 4 after the first 30

Ͳ day average production rate is multiplied by 0.6.

Example: For the first month the well makes an average 3.333 MMCFD. With 80% decline during the first

year, the well will make 0.667 MMCFD at the end of the first year (3.333

– 0.8(3.333)

= 0.667).  Then the

average daily production rate over 365 days is (3.33 + 0.667)/2

= 2.0 MMCFD which is the same as 3.333 x 0.6

= 2.0 MMCFD. Start Up   365 Days

MMCFD

Actual production during the first year is

represented by the area under the jagged line

which ultimately turns out to be ~730 MMCF. Start Up   365 Days

The jagged line representing daily production is

“smoothed” out usin g statistical methods.

Start Up   365 Days Start Up   365 Days

2 MMCFD

Leveled” out, projected daily gas production

rate vs. time

Total projected production for the first year is

represented by the area under the straight line 2 MMCFD x 365 days

= 730 MMCF The “smoothed” curve in BOX 2 is “straightened” out

using mathematical methods.Decline Over First 12 Months

= (1

Ͳ 12th Month of Production) / (1st Month of Production)

Decline Factor (facility

Ͳ specific)

= Average Production Over 12 Month Period / 1st Month of Production 5. Average the decline factors from each specific facility to obtain a representative decline factor for the formation.

## Introduction

The following pages explain the emission calculation methods applied to Oil and Gas (O&G) production facilities on the

Ft. Berthold Indian Reservation that fall into one of the following categories:

a) Existing, unpermitted (Part 49) facilities seeking synthetic minor limits; or 

b) The construction of a new facility.

The permitting official should note that emissions associated with the exploration and production of O&G resources

cannot be predicted with any degree of precision or accuracy until after it is determined the oil or gas well will actually

produce and site specific production data are collected and known. Therefore, unlike other stationary sources for which

projected emissions upon startup can be estimated in advance for purposes of pre

Ͳ construction air permitting,

emissions from O&G exploration and production facilities are only known post

Ͳ construction and completion. This

situation is unique to O&G exploration and production facilities and, therefore, requires a practical regulatory response.

To accommodate the need for registration pre

Ͳ construction Enerplus Resources (USA) Corporation (Enerplus) has taken

a conservative approach to emission calculations for the start

Ͳ up of new exploration and production facilities, and the

modification of existing facilities.

Applied control technologies have been referenced within this document for tank emissions and emissions from treater

flares. Emissions from other sources such as vehicle miles traveled, fugitive equipment leaks, truck loading, etc. are also

included in the calculations.



## Unique Issues with Bakken Pool VOCs

The composition of crude oil from the Bakken Pool (defined as wells in the Bakken, Sanish and Three Forks formations)

typically contains a high amount of lighter end components which have the potential to produce increased volumes of

flash emissions. The North Dakota Department of Health (NDDoH)

Ͳ Bakken VOC Task Force and industry have created

Bakken default values based on Bakken production wells which have been utilized in instances where site

Ͳ specific data is

unavailable.



## Potential to Emit

The federal regulations define "potential to emit" as:

“The maximum capacity of a stationary source to emit a pollutant under its physical and operational

design. Any physical or operational limitation on the capacity of the source to emit a pollutant, including

air pollution control equipment and restrictions on hours of operation or on the type or amount of fuel

combusted, stored or processed, shall be treated as part of its design if the limitation or the effect it

would have on emissions is federally enforceable.”

The PTE of VOCs, HAPs and other pollutants associated with oil and gas production have been calculated pre

Ͳ control for

determining source status. Post control emissions are also included to prove source ability to meet synthetic minor limit.



## Emission Factors

Emission factors relate the quantity of a pollutant released to an activity or production associated with the release of the

pollutant. Emission factors for engine emitting units have been obtained from the manufacturer documents. Additional

emission factors were taken from the U. S. Environmental Protection Agency’s (EPA) Office of Air Quality Planning and

Standards (OAQPS) AP

Ͳ 42 emission factors. The AP

Ͳ 42 is maintained by the Emission Factor and Inventory Group (EFIG)

and can be found online at the EPA’s Clearinghouse for Inventories & Emissions Factors (CHIEF):

http://www.epa.gov/ttn/chief/ap42/index.html

.2 The EPA’s CHIEF website ( http://www.epa.gov/ttn/chief/index.html ) contains information on and links for emissions

inventories, emissions factors, emissions modeling, and emissions monitoring.



## Regulated Air Pollutant Sources

When calculating facility emissions, each potential emitting unit located on the facility was considered to determine

source potential to emit. Generally, the following are the most common emission sources and the type of regulated air

pollutants they may emit at a typical O&G production facility:

a) Oil/Condensate Tanks

– VOC, HAP, H2S (NOx, CO, SO2 when controlled)

b) Treater Flares

– VOC, HAP, NOx, CO, H2S, SO2

c) Heaters/Burners

– VOC, HAP, NOx, CO, SO2

d) Truck Loading

– VOC, HAP

e) RICE Engines

– VOC, HAP, NOx, CO

f) Pneumatic Pumps

– VOC, HAP

g) Pneumatic Controllers

– VOC, HAP



## Emission Calculation

A facility’s emissions are calculated in an Excel workbook. The spreadsheet will serve two functions in that it will provide

a simple way of calculating facility

Ͳ wide emissions, as well as insuring that emissions are calculated in a manner similar

to those currently applied in states bordering the facility locations.

The Enerplus Emission Calculations Workbook contains the following 10 tabs:

a) Input

– The necessary data to perform calculations applied throughout the workbook shall be entered on this

tab.

b) RICE Input

– The necessary data to perform the required calculations for RICE shall be entered on this tab.

c) Emission Summary

– The calculated emissions are summarized by source and pollutant on this tab.

1) Oil/Condensate Tanks

– The tank vapor emissions are calculated here.

2) Equipment Leaks

– Connector, flange, and valve leaks are calculated here.

3) Treater Flare

– The treater flare emissions are calculated here.

4) Treater Burner

8) Pneumatic Controllers –The pneumatic controller emissions are calculated here.



## Emission Calculation Procedure

The calculation workbook was completed per the detailed process below:



### Production Data

Line 3: New wells: the average daily production for a facility that has not been producing shall be calculated by applying

a conservative estimation based on an average from owner/operator wells that have production data for a year or more.

Existing wells: the average daily production in BOPD shall be calculated based on the most recent year of production.3 Line 4: New wells: the average daily production for a facility that has not been producing shall be calculated of gas in

Mscf per day, based on an average from owner/operator wells that have been in production for a year or more. Existing

wells: enter the average daily production in Mscf, based on the most recent year of production.

Line 5: New wells: enter 0.46 on this line (See calculation in Appendix D). Existing wells that have produced for more

than 18 months shall use a decline factor of 1.

Decline Factor Calculation Steps

1) For each month of the first 12 months of production, sum the production data to calculate a monthly total.

2) Calculate a decline in production over the first 12 months by applying the following formula:

Decline Over First 12 Months

= (1

Ͳ 12 th Month of Production)/ (1 st Month of Production)

3) Calculate an average of the production data over the 12 month period.

4) Calculate the decline factor for that facility by applying the following formula:

Decline Factor (facility

Ͳ specific)

= Average Production Over 12 Month Period/ 1 st Month of Production

5) Average the decline factors from each specific facility to obtain a representative decline factor for the

formation.

For further detail on decline factor calculation see Appendix D.2.

Line 6: The predetermined first year average daily oil production rate (BOPD) which is calculated by multiplying the

average daily rate entered on Line 3 by the decline factor entered on Line 5.

Line 7: The predetermined first year average daily gas production rate (Mscfd) which is calculated by multiplying the

average daily rate entered on Line 4, by the decline factor entered on Line 5.



### Oil/Condensate Tank Data

Emissions from storage tanks that store crude oil (or other process condensate) include flashing losses, working losses,

and breathing losses. Vapors containing regulated pollutants are released from solution in hydrocarbon liquids as the

liquids are transferred from higher pressure vessel (separator) to lower pressure vessel (storage tank). These vapors are

called flashing losses. Vapors escaping from hydrocarbon liquids while they are stored in atmospheric tanks are called

standing/working/breathing (S/W/B) losses. Standing losses are essentially evaporation losses. Working losses are those

caused by decreased/increased tank vapor space occurring as the tank is filled/emptied. Breathing losses are those

promoted by daily ambient changes in air temperature and barometric pressure. Flashing losses are normally greater

than the working and breathing vapor losses. Oil/Condensate Tank emissions include all S/W/B losses and flashing

emissions.

The workbook calculates the tank emissions by using either an actual direct measurement (scf/bbl), a representative

average or by using the Bakken Pool emission factor of 97.91 scf/bbl. In addition to the scf/bbl value, the workbook uses

the molecular weight, lower heating value of the fuel and the VOC, HAP, CH 4 , and CO 2 weight fractions of the tank

vapors to calculate the tank vapor emissions.

## Qualitative Air Quality Impact Analysis

This permit application does not include an air quality impact analysis as the effects on air emissions from this source are

not anticipated to impact air quality in the region. A qualitative approach to modeling the air quality impact was

performed based on the following items:

x Natural gas is being used to fuel equipment on the facility and typical emissions from utilizing this type of fuel

are insignificant.

x The region for which the source is operating is classified as an attainment area; therefore, there are no

significant air quality issues in the region for which this source would impact.

Due to the above factors, the proposed emissions under this permit are not anticipated to impact air quality in the

region.

## P OTENTIAL TO 

## E MIT

Based on this facility’s maximum annual operational potential to emit (PTE) calculations presented in

Attachment C of the Application for New Construction, this facility will require a federally

Ͳ enforceable

limitation on emissions to avoid an otherwise applicable federal Clean Air Act program, rule or

requirement, including Prevention of Significant Deterioration (PSD) and an applicable Title V Operating

Permit.

Requested Limitation. To limit this facility’s PTE, Enerplus is requesting mandated installation, operation

and maintenance of 98% destruction removal efficiency emission control equipment.

Combustor size(s) and quantity needed are likely to change as:

x Drill schedules change (i.e. all planned wells at a pad are not drilled at the same time; therefore

affecting the cumulative production rates and combustion unit sizing);

x Actual production rates are determined (i.e. actual production rate is lower than the

conservative average herein); and

x Combustion unit availability closer to the time of well construction.

As such, vendor guarantees are included in Attachment G for the selected combustion units from which

Enerplus will utilize based on actual well production values of natural gas. These combustion unit(s) are

guaranteed to ensure 98% removal of VOC and HAPs; therefore, the most appropriate unit of this

selection will be installed as actual well construction/drilling commences. If an alternate combustion

unit(s) is selected, Enerplus will provide the EPA with the guarantee to ensure 98% removal of VOC and

HAPs for approval prior to installation.

Effect on Emissions. Estimates of the facility’s anticipated emissions with and without the above

requested limitations are provided in the emission summary in Appendix C.

Emission of hydrofluorocarbons (HFC), perfluorocompound (PFC), sulfur hexafluoride (SF6), ammonia

and lead are not typical of oil and gas production, and are therefore not anticipate to be emitted from

Test Report – Cimarron Energy Parshall Flare



### page 1 **1. Introduction**

Air Pollution Testing, Inc. (APT) was contracted by Cimarron Energy, Inc. to conduct

source emission testing services at a facility near Parshall, North Dakota.

The purpose of the test program was to determine the concentrations and mass

emission rates of oxygen (O 2 

### ), carbon dioxide (CO 2 

### ), carbon monoxide (CO), methane

(CH 4 

### ) and non-methane organic compounds (NMOC) at both the inlet and outlet

sampling locations of an enclosed flare stack. The unit is fed with off gas from various

facility processes. Concurrent inlet gas velocity measurements, as well as pilot light

data, were collected for the determination of total inlet emissions. All of the above data

were combined to determine the overall destruction removal efficiency (DRE) of the unit.

The emissions testing was conducted under three different operating conditions; 1 oz., 4

oz. and 10 oz. inlet feed pressures.

Table 1.1 provides contact information for key personnel involved in the test program.

### page 3 **4. Test Method Details**

4.1. Stack Gas Velocity, Volu metric Flow Rate and Moisture

Stack gas velocity, volumetric flow rate and moisture (H 2 

### O) content were measured in

accordance with EPA Methods 1, 2 and 4.

Each sampling period consisted of conducting a temperature and differential pressure

traverse of the stack using a K-type thermocouple and an S-type pitot tube. Concurrent

with each traverse, a sample of gas for moisture determination was extracted from the

stack at a constant flow rate of no more than 0.75 cubic feet per minute (cfm). The gas

sample passed through a stainless steel probe, through a series of four (4) chilled glass

impingers, and through a calibrated dry gas meter. See Appendix 4 – Schematics for a

diagram of the EPA Methods 1, 2 and 4 sampling train.

Prior to sampling, the first two impingers were each seeded with 100 milliliters of water.

The third impinger was empty. The fourth impinger was seeded with 250 grams of dried

silica gel. Following sampling, the moisture gain in the impingers was measured

gravimetrically to determine the moisture content of the gas.

All of the above data were combined with concurrently collected diluent (O 2 

### and CO 2 

### )

data to calculate the stack gas velocity and volumetric flow rate in units of feet per

second (ft/sec), actual cubic feet per minute (acfm), dry standard (1 atmosphere and

68°F) cubic feet per minute (dscfm), and pounds per hour (lb/hr).

4.2. Diluent, Carbon Monoxide and Non-methane Hydrocarbons – Flare Exhaust

O 2 

### , CO 2 

### , CO and NMOC emission concentrations were measured in accordance with

EPA Methods 3A (O 2 

### and CO 2 

### ), 10 (CO) and 25A (NMOC).

Each sampling period consisted of extracting a gas sample from the stack at a constant

flow rate of approximately three liters per minute (lpm). The sample passed through a

refrigeration-type gas conditioner to remove moisture and into the sampling port of a

TECO Model 48H gas filter correlation infrared CO analyzer, a Servomex Series 1400

paramagnetic O 2 

### / non-dispersive infrared CO 2 

### analyzer and a Thermo Model 55 flame

ionization analyzer equipped with a methane separator. The gas conditioner was

bypassed for the NMOC analyzer. The gas concentrations were displayed on the

analyzer front panels in units of either parts per million, dry volume basis (ppmvd – CO),

percent, dry volume basis (%vd – O 2 

### and CO 2 

### ), or parts per million, wet volume basis as

propane (ppmvw as C 3 

### H 8 

### – NMOC) and logged to a computerized data acquisition

system (CDAS). Please see Appendix 4 – Schematics for a diagram of the EPA

Methods 3A, 10 and 25A sampling train.

Before and after each sampling period, the analyzers were challenged with calibration

gases to calibrate the instruments, to verify linearity of response, and to quantify zeroAPT Project: CIM1122

Test Report – Cimarron Energy Parshall Flare



### page 4 and span drift for the previous sampling period. The calibration gases were prepared

and certified in accordance with EPA Protocol 1. To ensure no system bias, the

analyzer calibrations were conducted by introducing all gases to the analyzers at the

sampling probe tip at stack pressure.

Following sampling, the CDAS data were averaged in one-minute increments, corrected

for instrumental drift, and reported as average emission concentrations for each

sampling period.

4.3. Total Hydrocarbon / NMOC – Flare Inlets

Methane and NMOC concentrations were measured in accordance with ASTM D-1945

and 1946, which are industry standard analytical methods for analysis of fuel gas type

samples. Samples were collected from each inlet in Tedlar bags for off-site

GC/FID/TCD analysis for C1 – C6+ hydrocarbons, oxygen, carbon dioxide and nitrogen.

The concentration data were combined with the pitot traverse data (condensate waste

gas) or manufacturer data (pilot light) to calculate flare inlet NMOC mass flow to

determine the control efficiency for NMOC.

Laboratory analysis of the waste gas sample indicated high oxygen and nitrogen from

likely sample leakage. The hydrocarbon and carbon dioxide concentrations were

normalized to remove the leakage. DRE was calculated on both a mass flow in/out

basis and by carbon balance.

## SUMMARY

On November 5, 1998, the Edmonton office of Maxxam Analytics Inc. conducted a source emission survey and efficiency

test on the Incinerator Exhaust Stack that was op erating on a Mobil well site (06-03-030-27-W4M) near the Mobil Lone

Pine Creek Gas Plant. Sampling was carried out on the separator inlet to determine concentrations of organic compounds

and water content. Sampling was carried ou t on the separator outlet to determin e concentrations of organic compounds,

total reduced sulphur compounds and water content. Samplin g was carried out on the incinerator exhaust stack to

determine concentrations of sulphur dioxide, oxides of nitrogen, carbon monoxide, total reduced sulphur compounds

and organic compounds. Furthermore, destruction efficiencies were determined for total reduced sulphur compounds

and organic compounds.

The summary of results is as follows:
