# Instructions

**U se of This Form** 

• Proposed new construction or modifications should first be evaluated to determine if the change is major under the major NSR program using the procedures at 40 CFR 52.21 (i.e., baseline actual to projected actual applicability test). If the proposed construction does not qualify as a major under that test, then it may be subject to the requirements of the minor NSR rule at 40 CFR 49.151.
**Helpful Definitions from the Federal Minor NSR Rule (40 CFR 49) –** This is not a comprehensive list.



## • 40 CFR 49.152(d) - Modification means any physical or operational change at a source that would cause an increase in the allowable emissions of the affected emissions units for any regulated NSR pollutant or that would cause the emission of any regulated NSR pollutant not previously emitted.
The following exemptions apply:
(1) A physical or operational change does not include routine maintenance, repair, or replacement.
(2) An increase in the hours of operation or in the production rate is not considered an operational change unless such increase is prohibited under any federally-enforceable permit condition or other permit condition that is enforceable as a practical matter.
(3) A change in ownership at a source is not considered a modification.

• 40 CFR 49.152(d) - Allowable emissions means ‘‘allowable emissions’’ as defined in §52.21(b)(16), except that the allowable emissions for any emissions unit are calculated considering any emission limitations that are enforceable as a practical matter on the emissions unit’s potential to emit.

• 52.21(b)(16) - Allowable emissions means the emissions rate of a stationary source calculated using the maximum rated capacity of the source (unless the source is subject to federally enforceable limits which restrict the operating rate, or hours of operation, or both) and the most stringent of the following:
(i) The applicable standards as set forth in 40 CFR parts 60 and 61;
(ii) The applicable State Implementation Plan emissions limitation, including those with a future compliance date; or
(iii) The emissions rate specified as a federally enforceable permit condition, including those with a future compliance date.Page 8 of 15

# Criteria Pollutant Emissions **Estimates**

 E stimates of Current Actual Emissions, Current Allowable Emissions, Post-Change Uncontrolled Emissions, and Post-Change Allowable Emissions for the following air pollutants: particulate matter, PM 10 

## , PM 2.5 

## , sulfur oxides (SOx), nitrogen oxides (NOx), carbon monoxide (CO), volatile organic compound (VOC), lead (Pb) and lead compounds, ammonia (NH 3 

## ), fluorides (gaseous and particulate), sulfuric acid mist (H 2 

## SO 4 

## ), hydrogen sulfide (H 2 

## S), total reduced sulfur (TRS) and reduced sulfur compounds, including all calculations for the estimates.

1. These estimates are to be made for each emission unit, emission generating activity, in addition to total emissions.

2. The information should include all of the supporting calculations, assumptions and references. Emission estimates must address all emission units and pollutants proposed and/or affected by the limitation and be presented in short term (e.g. pounds per hour) as well as annual (tons per year) units.

3. Any emission estimates submitted to the Regional Administrator must be verifiable using currently accepted engineering criteria. The following procedures are generally acceptable for estimating emissions from air pollution sources:

• Source-specific emission tests;

• Mass balance calculations;

• Published, verifiable emission factors that are applicable to the source. (i.e. manufacturer specifications)

• Other engineering calculations; or

• Other procedures to estimate emissions specifically approved by the Regional Administrator.

4. Guidance for estimating emissions can be found at http://www.epa.gov/ttn/chief/efpac/index.html

.

Current Actual Emissions: Current 

## actual emissions for a pollutant is expressed in tpy and generally is calculated by multiplying the actual hourly emissions rate in pounds per hour (lbs/hr) times actual hours operated (which is the number of hours in a year) and dividing by 2,000 (which is the number of pounds in a ton).

1. For an **existing air pollution source (permitted and unpermitted)** that operated prior to the application submittal, the current actual emissions are the actual rate of emissions for the preceding calendar year and must be calculated using the actual operating hours, production rates, in-place control equipment, and types of materials processed, stored, or combusted during the preceding calendar year. The emission estimates must be based upon actual test data or, in the absence of such data, upon procedures acceptable to the Regional Administrator.


## Current Allowable Emissions: Current allowable emissions for a pollutant is expressed in tpy and generally is calculated by multiplying the allowed hourly emissions rate in pounds per hour (lbs/hr) times allowed hours (which is the number of hours in a year) and dividing by 2,000 (which is the number of pounds in a ton).

1. “Allowed” means the source is restricted by permit conditions that limit its emissions and are enforceable as a practical matter (i.e., allowable emissions). The allowable emissions for anyPage 12 of 15 

## emissions unit are calculated considering any emissions limitations that are enforceable as a practical matter on the unit’s PTE.

2. For an **existing permitted air pollution source** that operated prior to the application submittal, the current allowable emissions are the allowable rate of emissions for the preceding calendar year and must be calculated using the permitted operating hours, production rates, in-place control equipment, and types of materials processed, stored, or combusted during the preceding calendar year.



## 3. For an **existing air pollution source** that does not have an established allowable emissions level prior to the modification must report the pre-change uncontrolled emissions.
Post-Change Potential Emissions (Potential uncontrolled emissions from proposed project): This is the maximum capacity of a source to emit a pollutant under its physical and operational design. This is expressed in tpy and generally is calculated by multiplying the maximum hourly emissions rate in pounds per hour (lbs/hr) times 8,760 hours (which is the number of hours in a year) and dividing by 2,000 (which is the number of pounds in a ton).
Post-Change Allowable Emissions: A source’s allowable emissions for a pollutant is expressed in tpy and generally is calculated by multiplying the allowed hourly emissions rate in pounds per hour (lbs/hr) times allowed hours (which is the number of hours in a year) and dividing by 2,000 (which is the number of pounds in a ton).

1. Unless the source is restricted by permit conditions or other requirements that are enforceable as a practical matter, the post-change allowable emissions would be equivalent to post-change uncontrolled emissions. For the post-change allowable emissions a lower level of allowable emissions may be proposed.

2. For physical or operational changes at minor sources and for minor physical or operational changes at major sources, the total increase in allowable emissions resulting from your proposed change would be the sum of following:

• 

## For each new emissions unit that is to be added, the emissions increase would be the potential to emit of each unit.

• 

## For each emissions unit with an allowable emissions limit that is to be changed or replaced, the emissions increase would be the allowable emissions of the emissions unit after the change or replacement minus the allowable emissions prior to the change or replacement. However, this may not be a negative value. If the allowable emissions of an emissions unit would be reduced as a result of the change or replacement, use zero in the calculation.

• 

## For each unpermitted emissions unit (i.e., a unit without any emissions limitations before the change) that is to be changed or replaced, the emissions increase would be the allowable emissions of the unit after the change or replacement minus the potential to emit prior to the change or replacement. However, this may not be a negative value. If the allowable emissions of an emissions unit would be reduced as a result of the change or replacement, use zero in the calculation.Page 13 of 15

# Modeling Analysis
Do I need to do a modeling analysis?

The Federal Minor New Source Review Regulations at 40 CFR 49.159(d) requires that a modeling analysis (AQIA) of proposed emissions be performed if there is reason to be concerned that new construction would cause or contribute to a National Ambient Air Quality Standard (NAAQS) or Prevention of Significant Deterioration (PSD) increment violation.

In addition, if the AQIA reveals that the new construction could cause or contribute to a NAAQS or PSD increment violation; such impacts must be reduced before a pre-construction permit can be issued.
To facilitate the protection of the NAAQS and PSD Increment, EPA Region 8 requests that those proposed activities that meet the following criteria perform an AQIA:
1. The proposed activity has air emissions that EPA Region 8 determines have the potential to cause adverse air quality effects for which an air quality impact analysis is necessary for an accurate assessment of the environmental impact of the activities proposed.

2. Modeling of proposed emissions is usually warranted, even though the proposed activity does not meet the modeling requirements, above, if it is reasonable to believe the new activity may cause or contribute to a violation of applicable ambient air quality standards or increments in circumstances such as:

(a) A substantial portion of the new or modified emissions have poor dispersion characteristics (e.g., rain caps, horizontal stacks, fugitive releases, or **building downwash** ) in close proximity to **ambient air** at the site boundary;

(b) The new or modified emissions are located in **complex terrain** (e.g., terrain above stack height in close proximity to the source); or

(c) The new or modified emissions are located in areas with existing air quality concerns.

(d) If you have questions about whether modeling may be necessary based on the 4 th 

## criteria above, please contact EPA Region 8’s Modeling Lead:

Gail Tonnesen Region 8 Modeling Lead Tonnesen.gail@epa.gov 303-312- 6113Page 14 of 15 

# What Kind of Air Quality Modeling Analysis Is Needed?

1. EPA Region 8 considers a stepped or phased approach to modeling to be appropriate, as follows:
Step 1: Qualitative Air Quality Assessment Step 2: Screening Modeling Analysis Step 3: Preliminary Modeling Analysis (refined modeling) Step 4: Full Impact Modeling Analysis (refined modeling) Step 5: PSD Increment and NAAQS Analysis Step 6: Additional Impact Analysis

2. Step 1: Qualitative Air Quality Assessment
Narrative description of the current air quality conditions and the expected impact the permitted source would have on that air quality. Some suggested factors to consider in the qualitative discussion could include meteorology, terrain, distance to ambient air, expected emissions, etc. If a convincing case cannot be made qualitatively that no impacts to air quality would be expected, a screening analysis should next be performed.

3. Step 2: Screening Analysis
For proposed new or modified sources that meet the modeling requirement criteria identified above, protection of air quality from proposed emissions may be shown by using a simple screening technique (e.g., SCREEN3 or AERSCREEN). Screening models are available for download at the EPA SCRAM website: http://www.epa.gov/ttn/scram/dispersion_screening.ht m . A pre-approved modeling protocol is not necessary prior to conducting a Screening Analysis.

4. If the proposed new or modified emission increases do not increase ambient concentrations of a pollutant by more than the significant impact levels, as compared to the SILs identified below, 

## no further modeling is necessary.
**Significant Impact Levels Pollutant Averaging Period Class II Area SIL**  **(ug/m 3**

## CO 1 hr 2,000 ppb 8 hr 500 ppb

**Note:** The Class I area SILs are provided as guidance and have not been formalized by EPA.Page 15 of 15 

## 5. Sources that cannot demonstrate protection of air quality using a screening technique should continue to the modeling requirements in **Step 3** through **Step 6** . Modeling in Steps 3 through 6 should be performed based an approved protocol.

6. Applicants are encouraged to contact the EPA Region 8 Modeling Lead prior to conducting any refined modeling analysis (Step 3 through Step 6) to obtain an approved protocol.


# What Should I Include In My Application If Modeling Is Necessary?

1. Approved Modeling Protocol
In order to expedite the permitting process, it is recommended that you include a protocol that has already been approved. An application will not be deemed complete until the protocol has been approved.

2. Modeling Results
In all cases, the modeling results should include the name of the model used, all input parameters, and the resulting output. Electronic copies of the modeling input/output files should be provided to EPA Region 8.

# I **nstructions**

**U se this form to provide general and summary information about the synthetic minor NSR**  **source (facility or plant) on Tribal lands and to indicate the emissions limitations requested. Submit this form once, in addition to FORM NEW, for each synthetic minor NSR source on**  **Tribal lands.**

**1. Who Can Request Federally-Enforceable Limitations Under the Tribal NSR Authority?**
The Tribal NSR Rule applies only to sources located within the exterior boundaries of an Indian reservation in the United States of America or other lands as specified in 40 CFR part 49, collectivelyreferred to as “Indian country”. So, to use the authority in the Tribal NSR Rule to create federallyenforceable limitations, a facility must be located within Indian country. Land ownership status (for example, whether the land is owned by a Tribal member or whether the land is owned in fee or in trust) does not affect how the rule applies.
**2. Who Might Want to Request Federally-Enforceable Limitations?**
The primary reason for requesting federally-enforceable limitations is to avoid an otherwise applicable federal Clean Air Act program, rule or requirement. Many federal Clean Air Act programs use a source’s “potential to emit” (PTE) air pollution to determine which rules or requirements apply. A facility’s PTE is based on the maximum annual operational (production, throughput, etc) rate of the facility taking into consideration the capacity and configuration of the equipment and operations. Emission or operational limits can also be taken into consideration as maximums if they are federally enforceable. So, using a synthetic minor NSR permit to establish federally enforceable limitations can lower a facility’s PTE and possibly allow the facility to avoid certain federal Clean Air Act requirements.
Three examples of federal Clean Air Act programs that use PTE to determine whether they apply are (1) the Prevention of Significant Deterioration (PSD) construction permitting program, (2) the Title V operating permit program, and (3) the Maximum Achievable Control Technology (MACT) program. For example, existing sources that are considered “major” for Title V (meaning they have the potential to emit air pollution at levels defined in that rule as “major”) must apply for a Title V operating permit. If a source accepts a federally-enforceable limitation through a synthetic minor NSR permit that reduces their PTE to below the “major” threshold, and the source does not meet any of the other requirements that would trigger applicability to the part 71 program, then the source no longer needs a Title V operating permit. When planning for the construction of a new source or expansion of an existing source, a source can also accept limitations on PTE (using a synthetic minor NSR permit) that allow the source to avoid PSD. Limitations on PTE can similarly help a source to avoid new MACT standards that would otherwise apply to the source.

**3. Section B. ATTACHMENTS**
This section lists the information that must be attached to the application form for each requestedlimitation. The requested limitation(s) must be described for each affected emissions unit (or pollutantgenerating activity) and pollutant and must be accompanied by the supporting information listed on the form and described below. Note that applicability of many federal Clean Air Act requirements (such as Title V, PSD and MACT) is often based on facility-wide emission levels of specific pollutants. In thatPage 3 of 4 

## case, all emissions units at a facility and all pollutants regulated by that given rule or regulation must be addressed by this section of the application form.

**Item 1 –** The requested limitation and its effect on actual emissions or potential to emit must be presented in enough detail to document how the limitation will limit the source’s actual or potential emissions as a legal and practical matter and, if applicable, will allow the source to avoid an otherwise applicable requirement. The information presented must clearly explain how the limitation affects each emission unit and each air pollutant from that emission unit. Use the information provided in response to Item 4 below to explain how the limitation affects emissions before and after the limitation is in effect.

**Item 2 –** For each requested limitation, the application must include proposed testing, monitoring, recordkeeping and reporting that will be used to demonstrate and assure compliance with the limitation. Testing approaches should incorporate and reference appropriate EPA reference methods where applicable. Monitoring should describe the emission, control or process parameters that will be relied on and should address frequency, methods, and quality assurance.

**Item 3 –** The application must include a description and estimated efficiency of air pollution control equipment under present or anticipated operating conditions. For control equipment that is not proposed to be modified to meet the requested limit, simply note that fact; however, for equipment that is proposed to be modified (e.g. improved efficiency) or newly installed to meet the proposed limit, address both current and future descriptions and efficiencies. Include manufacturer specifications and guarantees for each control device.

**Items 4 –** Any emission estimates submitted to the Regional Administrator must be verifiable using currently accepted engineering criteria. The following procedures are generally acceptable for estimating emissions from air pollution sources:
(i) Source-specific emission tests; (ii) Mass balance calculations; (iii) Published, verifiable emission factors that are applicable to the source. (i.e., manufacturer specifications). 

## (iv) Other engineering calculations; or (v) Other procedures to estimate emissions specifically approved by the Regional Administrator.
Post-Change Allowable Emissions: A source’s allowable emissions for a pollutant is expressed in tpy and generally is calculated by multiplying the allowed hourly emissions rate in pounds per hour (lbs/hr) times allowed hours (which is the number of hours in a year) and dividing by 2,000 (which is the number of pounds in a ton).

**Item 5** - New construction projects that have the potential to emit GHG emissions of at least 100,000 tpy CO 2 

## e and 100 or 250 tpy on a mass basis, modifications at existing PSD facilities that increase GHG emissions by at least 75,000 tpy CO 2 

## e and minor sources that increase GHG emissions by at least 100,000 tpy CO 2 

## e and 100 or 250 tpy on a mass basis are subject to PSD permitting requirements, even if they do not significantly increase emissions of any other pollutant. As such, any requested limits to avoid PSD must take into account greenhouse gases.
Therefore, please include in your permit application estimates of the potential emissions of the following pollutants before and after proposed emission controls. More information about GHG permitting and how to calculate CO 2

# 1.0 **I NTRODUCTION** 

**1.1. Summary** 
Dakota-3 E&P Company, LLC (Dakota-3) is submitting this application for a Prevention of Significant Deterioration (PSD) synthetic minor permit to the Environmental Protection Agency (Agency) in accordance with the requirements of the Consent Agreement dated August 29, 2011, regarding compliance with the Federal Minor New Source Review (NSR) Rule (40 CFR 49) adopted pursuant to the Federal Clean Air Act. Dakota-3 signed the Consent Agreement to address the unique situation where a synthetic minor source permit could not be obtained prior to commencing construction because the new Tribal Minor NSR Rule’s August 30, 2011, implementation date did not feasibly allow time for preparation, review and processing of applications and permits.
Under the Consent Agreement, Dakota-3 is required to submit, by October 1, 2011, synthetic minor preconstruction permit applications for all oil and gas production facilities within the Fort Berthold Indian Reservation (FBIR) in North Dakota. These applications are for facilities that are anticipated to commence construction between August 31, 2011, and December 31, 2011 (Table A-2 of the Consent Agreement).
Dakota-3 is proposing to construct and operate the Delores Sand 29-32H Oil and Gas (O&G) production facility on the FBIR. Included in this application for a synthetic minor permit are allowable emissions specified by requested federally enforceable permit conditions that limit the emissions from the facility to below the PSD major source thresholds. These limits can be found in Section 4.0 of the application.



# 1.2. **Site Location**
The Delores Sand 29-32H Pad is proposed to be located in the northwest 1⁄4 of the northeast 1⁄4 Section 29, Township 151 North, Range 94 West, McKenzie County, on the FBIR in North Dakota.



# 1.3. **Site Description**
At the proposed Delores Sand 29-32H Pad there will be one oil and gas well that is currently proposed to produce to the facility. The facility will be situated on an approximately ten acre site, with an elevation of approximately 2,000 feet (mean sea level), in McKenzie County, North Dakota. The surrounding area is mainly used for agriculture and livestock grazing. The proposed pad’s associated well name is:

1. Delores Sand 29-32H
The name of the well may be subject to change due to landowner requirements, drilling location changes, timing of well leases, etc. The Agency will be notified if the name changes.Delores Sand 29-32H Pad 09/30/11 pg. 2 NSR Synthetic Minor Permit Application Project #: WEP211324 

# 2.0 NARRATIVE DESCRIPTION

This section of the application provides a detailed description of the operations at the Delores Sand 29-32H Pad. For purposes of estimating emissions from this facility, the first twelve-month potential production from the proposed well at this facility was used. These production rates can be found in Attachment B, Emission Inventory.
The entire pad facility will consist of the following primary production equipment and capabilities.
1 - Heater Treater/Separator 1 - Line-Heater (0.75 MMBtu/hr max) 4 - Oil Production Tanks 1 - Gasoline Recycling Pump 1 - Produced Water Tank 1 - Electric Lifting Unit 1 - Oil and Gas Producing Well 1 - Truck Loading Rack 1 - Manufactured Produced Gas Flare 1 - Diesel Engine 1 - Manufactured Enclosed Tank Vapor Combustor 1 - LACT Unit


## The oil/gas/water emulsion being produced from the well is transported up the wellbore using an electric lifting unit. The emulsion from the well producing to this site istransported in a closed system to individual two-phased separator and then to the threephase separator (heater treater). The initial two-phase separator reduces the pressure of the oil/gas/water emulsion to allow the gas to separate from the oil and water. The heater treater then reduces the pressure closer to ambient pressure and heats the leftover emulsion using a flame-arrested line-heater. The combination of higher temperatures and low pressures allow for additional separation of the gas/oil/water phases from each other because of differences in densities. The line-heater is fueled by onsite produced casing head gas that is routed to the heater’s combustion chamber. Propane may also be used as an alternative fuel if necessary. Following the heater treater the oil and water are routed to their separate storage tanks.
The produced casing head gas is transferred from the two-phase separator to the sales gas pipeline. An onsite utility flare serves as an emergency backup in the event that the gas cannot be placed into the sales line. The oil and water production tank’s working, standing, breathing, and flashing vapors are routed to an enclosed combustion device. The stored oil is typically transported for sale via the Lease Automated Custody Transfer (LACT) unit, with the truck loadout serving as an emergency backup if there was a malfunction with the oil pipeline. Produced water is stored in the onsite water storage tank until it is transported offsite using the water pipeline.
At the facility, there is a small gasoline fueled pump located near the production storage tanks. This pump is commonly known as a “transfer” or “recycle.” The pump is used to periodically recycle the liquids (oil/water) in the bottom of the production tanks back into the heater treater for further separation. Otherwise, the facility is completely electrified; however, the electricity lines have not yet been installed at the facility. An onsite diesel genset engine will provide electricity until transmission lines are installed.Delores Sand 29-32H Pad 09/30/11 pg. 3 NSR Synthetic Minor Permit Application Project #: WEP211324 

## A process flow diagram and plot plan of the site is shown in Attachment H.Delores Sand 29-32H Pad 09/30/11 pg. 4 NSR Synthetic Minor Permit Application Project #: WEP211324 

# 3.0 POTENTIAL TO EMIT ESTIMATE

In estimating the average production for the first twelve months, a decline curve was developed. The decline curve takes into account the fact that the initial production of the well will greatly decline over the initial twelve months of production. Assuming that the well’s production would be equivalent to the initial production will grossly overestimate production and is not realistic for how an oil and gas well operates. The decline curve calculated for this facility was developed using existing well data from wells previously drilled and producing in the same region. The confidential decline curve estimations are included in Attachment I of the application.Delores Sand 29-32H Pad 09/30/11 pg. 5 NSR Synthetic Minor Permit Application Project #: WEP211324

## Potential emissions from this facility originate primarily from the heater treater lineheater emissions, the production storage tank uncontrolled emissions, truck loading emissions, diesel genset emissions, and fugitive emissions (e.g., truck loading, equipment leaks and road dust). The maximum design capacity of the engine and natural gas-fired external combustion unit, in conjunction with maximum annual anticipated oil and gas production rates of this facility, were used in determining the facility’s potential to emit (PTE). The oil, gas, and water production rates were estimated by using data from recently drilled wells in the same region and extrapolating the rates for this proposed pad.
The potential emissions are stated in the Application for New Construction (Form NEW), Table E(i) – Proposed New Facility. The emissions from the facility fall into the following categories (i.e., emitting units).
1. Production Storage Tanks (Oil and Water); 2. Casing Head Gas (Produced Gas); 3. Reciprocating Internal Combustion Engines (Recycle Pump Engine and Diesel Genset) 4. Natural Gas External Combustion Unit (Heater Treater Line-Heater); 5. Truck Loading 6. Miscellaneous Fugitive Emissions (Fugitives);


# 3.1 Production Storage Tank VOC Emissions
To estimate the uncontrolled PTE of the production tank’s vapors (working, breathing, standing, and flashing), extended BTEX low pressure oil analyses were taken from representative wells producing out of the same geological region. E&P Tanks V2 was used to calculate the production tank’s vapors using the anticipated maximum production rates, area-specific ambient pressure/temperature data, representative process operating conditions, and sampled analytical data. The E&P Tanks output summary includes all of the needed input data in the emission inventory, such as the vapor rate that is produced from the tanks (scf/bbl), the mol% of the vapor components, such as VOCs, HAPs, GHGs, etc.
All applicable uncontrolled emissions from the storage tanks calculations, low pressure analytical data, and E&P TANKS program inputs and outputs are provided in the attachments.


# 3.2 Produced Casing Head Gas Emissions

At the two-phase separator, +90% of all of the initial casing head gas is separated and sent to the gas sales pipeline. After the initial separation occurs, the leftover emulsified oil/gas/water is transferred to the three-phase heater treater. The heater treater then separates the residual gas from the oil and water. Due to the reduced pressure of the heater treater, the sales pipeline pressure is too high to overcome; therefore, the residual gas is routed to the onsite utility flare. Furthermore, if the gas sales pipelineDelores Sand 29-32H Pad 09/30/11 pg. 6 NSR Synthetic Minor Permit Application Project #: WEP211324

## pressure increases to the point at which the produced casing head gas from the twophased separator cannot be sold or the gas pipeline has a malfunction, the flare serves as an emergency backup.


# 3.3 Reciprocating Internal Combustion or Compression Ignition Engine
Diesel engine connected to generator provide the facility with electricity. The potential emissions from the engine are estimated by assuming the engine is operating 8,760 hours per year and applying the federally required 40 CFR 63 Subpart JJJJ or 40 CFR 60 Subparts IIII and ZZZZ emission limits as applicable.



# 3.4 Natural Gas External Combustion Unit Emissions
The natural gas external combustion unit at the facility is the heater treater line-heater. The heater is rated to a maximum capacity of 750,000 Btu/hr. The emissions are based on AP-42 factors and assume the heater is running 8,760 hours per year.


# 3.5 Truck Loading Emissions
The facility is connected to the oil pipeline via the LACT unit; therefore, no emissions are associated with truck loading. The only time truck loading would occur is under emergency or malfunction situations.


# 3.6 Fugitive Emissions: Dust and Equipment Leaks
Fugitive emissions from equipment leaks and dust are not required to be estimated for purposes of potential to emit within the NSR permitting program. However, the fugitive emissions will be estimated after a final permit is issued and production begins in order to track to the twelve-month rolling average actual emissions. The fugitive leak emissions primarily consist of leaks from connectors, open-ended lines, valves, pumps, etc. These emissions will be estimated using EPA’s average emissions factors for total hydrocarbon emissions from O&G production operations. The fugitive dust emissions will be estimated using AP-42 factors to capture the emissions associated with vehicle traffic at the location.Delores Sand 29-32H Pad 09/30/11 pg. 7 NSR Synthetic Minor Permit Application Project #: WEP211324 

# 4.0 EMISSIONS AND OPERATIONAL LIMITS REQUESTS

Datoka-3 is requesting emissions and operational limits at the Delores Sand 29-32H Pad in order to obtain a synthetic minor status with regard to the NSR permitting programs. The federally enforceable permit conditions will allow Dakota-3 to operate the facility while emitting less than the PSD major source thresholds of 250 tons per year of a regulated criteria pollutant, 10 tons per year of an individual HAP, and 25 tons per year of all emitted HAPs.


# 4.1 Production Storage Tank Emissions
The majority of emissions associated with the facility occur from the working, breathing, standing, and flashing vapors from the production storage tanks. Therefore, Dakota-3 will control the storage tank VOC and HAP emissions by installing an enclosed smokeless combustion device that has been independently tested and certified to exceed the requirements of 40 CFR 60.18 at 98% destruction efficiency (DRE). Although this control device is certified to meet 99% DRE, Dakota-3 will assume the minimum required 98% DRE for purposes of calculating the controlled tank vapor emissions. This control device will allow Dakota-3 to apply a 98% control efficiency to the uncontrolled PTE. On this basis, the requested emission limit from the storage tanks is: 4.92 tons per year of VOCs.


# 4.2 Reciprocating Internal Combustion or Compression Ignition Engines

Dakota-3 will be required to limit the emissions from any reciprocating internal combustion or compression ignition engine being operated at the facility due to the federally enforceable requirements of 40 CFR 63 Subpart JJJJ or 40 CFR 60 Subparts IIII and ZZZZ, as applicable.Delores Sand 29-32H Pad 09/30/11 pg. 8 NSR Synthetic Minor Permit Application Project #: WEP211324 

# 5.0 ALLOWABLE EMISSIONS

The allowable emissions are the new estimated controlled potential to emit based on the federally enforceable controls and limits requested in Section 4. The allowable emissions are also presented in the Application for New Construction (Form NEW), Table E(i) – Proposed New Facility.


# 5.1 Storage Tank Emissions
The storage tank controlled emissions are estimated by applying 98% control efficiency to the uncontrolled VOC, HAP, and CH 4 

## emissions. Although the VOC, HAP, and CH 4 

## emissions are reduced by the smokeless combustion device, CO, NO x 

## , PM, PM 10 

## , PM 2.5 

## and N 2 

## O emissions are created by the combustion process. These emissions estimates are calculated using AP-42 factors and applying the weight percentages of the criteria pollutant and greenhouse gas components from a representative gas analysis.


# 5.2 Produced Casing Head Gas Emissions
As stated in Section 3, the produced casing head gas is transferred to the gas sales pipeline. However, the residual gas released from the oil/gas/water emulsion in the heater treater will be sent to the onsite utility flare. Furthermore, if the gas sales pipelinepressure increases to the point at which the produced casing head gas from the twophased separator cannot be sold or the gas pipeline has a malfunction, the flare serves as an emergency backup. No limits have been requested for the produced casing head gas emissions at the facility; therefore, the emissions estimate is equal to the potential to emit.


# 5.3 RICE Engine Emissions
No limits have been requested for the RICE at the facility. Dakota-3 is required to meet the federally enforceable emission standards depending on the size (hp) and date of manufacture; therefore, the emissions estimate is equal to the uncontrolled potential to emit.



# 5.4 Natural Gas External Combustion Unit Emissions
No limits have been requested for the natural gas external combustion unit (0.5-0.75 MMBtu/hr heater treater line-heater) at the facility; therefore, the emissions estimate is equal to the uncontrolled potential to emit.Delores Sand 29-32H Pad 09/30/11 pg. 9 NSR Synthetic Minor Permit Application Project #: WEP211324 

# 5.5 Truck Loading Emissions

The facility is connected to the oil pipeline via the LACT unit; therefore, no emissions are associated with truck loading. The only time truck loading would occur is under emergency or malfunction situations with the oil pipeline; therefore, there are no emissions associated with truck loading.


# 5.6 Fugitive Emissions: Dust and Equipment Leaks
Fugitive emissions from equipment leaks and dust are not required to be estimated for purposes of potential to emit within the NSR permitting program. However, the fugitiveemissions will be estimated after a final permit is issued in order to track the twelvemonth rolling average actual emissions. The fugitive leak emissions primarily consist of leaks from connectors, open-ended lines, valves, pumps, etc. These emissions will be estimated using EPA’s average emissions factors for total hydrocarbon emissions from O&G production operations. The fugitive dust emissions will be estimated using AP-42 factors to capture the emissions associated with vehicle traffic on the location.


# 5.7 Diesel Storage Tank Emissions
There will be an onsite storage tank at this facility to store diesel fuel that will be utilized in the diesel genset. This tank will be either a horizontal or vertical 1,000 gallon tank. Emissions for this tank were estimated using EPA TANKS 4.09d and determined to be less than 0.01 tpy. Because of the low level of emissions from this equipment, it has been determined to have insignificant emissions. The EPA TANKS 4.09d emissions summary output is in Attachment J.Delores Sand 29-32H Pad 09/30/11 pg. 10 NSR Synthetic Minor Permit Application Project #: WEP211324 

# 6.0 PROPOSED MONITORING AND RECORDKEEPING

As per the Application for Synthetic Minor Limit Request (Form SYNMIN), Page 1 (B), ATTACHMENTS, Item, 2, Datoka-3 is required to propose testing, monitoring, recordkeeping, and reporting requirements that will be used to demonstrate and assure compliance with the proposed allowable emissions.


# 6.1 Production Storage Tanks
The production storage tanks will have their flashing and standing/working/breathing vapors routed by a closed-vent system to equipment designed to capture the VOC and total HAP emissions generated at the facility for sale or other beneficial purposes, or an emissions control device that achieves a minimum of 98% destruction efficiency. Dakota-3 will follow the tank manufacturer’s recommended maintenance schedule and procedures to ensure optimum performance. Furthermore, Dakota-3 will employ the following methods to ensure the tank vapors are efficiently being routed to the requested proposed device(s):
a. Thief hatch covers will be weighted and properly seated; b. Pressure relief valves (PRV) will be set to release at a pressure that will ensure flashing, and standing/working/breathing losses are routed through a closed-vent system to equipment designed to capture the VOC and total HAP vapors. The vapors will be routed to equipment designed for sale or other beneficial purpose, or an emissions control device; and c. Periodic measurements of the peak pressure and vacuum values in the vapor recovery and control systems will be conducted to ensure that the pressure and vacuum relief set-points are not being exceeded (e.g., due to fouling or increased activity levels) resulting in venting and possible damage to equipment.
Monitoring Requirements:
Dakota-3 will estimate the emissions from the production storage tanks by performing one of the following methods:
a. Direct measurement of standing/working/breathing losses by sampling and lab analysis; b. EPA TANKS 4.0.9d to calculate standing/working/breathing losses; c. Direct measurement of flashing emissions by sampling and lab analysis; d. Process simulator such as PROMAX, HYSIM, HSYS using site-specific sampling and lab analysis to calculate flashing emissions in conjunction with EPA TANKS 4.0.9d to calculate standing/working/breathing losses; e. API E&P TANKS Software V2.0 using representative sampling and lab analysis to calculate standing/working/breathing losses and flashing emissions; or f. Other methods approved by EPA.Delores Sand 29-32H Pad 09/30/11 pg. 11 NSR Synthetic Minor Permit Application Project #: WEP211324 

## Recordkeeping Requirements:
Total VOC, total HAP, and any single HAP emissions, in tons, from production storage tanks will be calculated and recorded at the end of each month, beginning with the first full calendar month after operations commenced. Prior to twelve full months of operation, Dakota-3 will, at the end of each month, add the emissions for that month to the calculated emissions for all previous months since operations commenced, where applicable, and record the total. Thereafter, Dakota-3 will, at the end of each month, add the emissions for that month to the calculated emissions for the preceding eleven months and record a new twelve-month total.
Dakota-3 will keep records of all input parameters and calculations, including the input and output reports for the models, used to determine the monthly emissions.


# 6.2 Production Storage Tank Emissions Control Device

Dakota-3 will properly operate and maintain the engines as per the manufacturer’s specifications to ensure compliance with the above standards. If the engines emissions are not certified to meet the required standards, Dakota-3 will have performance tests conducted on the engines as required by the applicable subparts.



# 6.5 Natural Gas-Fired External Combustion Units
Due to the insignificant emissions associated with the 0.5 to 0.75 MMBtu/hr natural gas (or propane) fired line-heater, no monitoring or recordkeeping requirements are being proposed by Dakota-3.Delores Sand 29-32H Pad 09/30/11 pg. 15 NSR Synthetic Minor Permit Application Project #: WEP211324 

# 6.6 Truck Loading
LACT units are utilized to transport the oil and water at this facility into their respective pipelines. However, there is a truck loading rack at the facility in case of a malfunction. If the truck loading rack must be used in an emergency or malfunction situation, the tank trucks will be loaded using submerged fill.


# 6.7 Fugitive Emissions: Equipment Leaks
Dakota-3 will minimize leaks of volatile organics from each piece of equipment in hydrocarbon service at this facility.
Work Practice and Operational Requirements:
a. At a minimum, Dakota-3 will detect and repair leaks at each tank thief hatch, centrifugal compressor vent, reciprocating compressor vent, instrument, meter, diaphragm, pressure relief device, dump arm, open-ended valve or line, vent line, flange, connection, fitting, or any other appurtenance employed to contain and collect vapors and transport them. b. Dakota-3 will make the first attempt to repair any leaking equipment within five days after the leak is detected. c. Any leaking equipment will be repaired as soon as practicable, but no later than 15 days after the leak is initially detected, unless the repair is technically infeasible without a facility shutdown. Such equipment will be repaired before the end of the first facility shutdown, after the leak is initially detected. Dakota-3 will make the first attempt to repair any leaking equipment within five days after the leak is detected. Dakota-3 will minimize leaks of volatile organics from each piece of equipment in hydrocarbon service at this facility.
Monitoring Requirements:
a. Dakota-3 will conduct leak detection monitoring on an annual basis. If no instrument reading of 10,000 ppm or greater is measured for two consecutive quarterly monitoring periods, the required monitoring frequency will change from quarterly to semi-annual. If no instrument reading of 10,000 ppm or greater is measured for two consecutive semi-annual monitoring periods, the required monitoring frequency will change from semi-annual to annual. If any single instrument reading of 10,000 ppm or greater is measured, the required monitoring frequency will change back to quarterly. b. Dakota-3 will use one of the following methods to conduct leak detection of the equipment: i.

# 6.8 General Recordkeeping Requirements
Total VOC (or VOC, total HAP, and any single HAP) emissions, in tons, from each piece of equipment will be calculated and recorded at the end of each month, beginning with the first full calendar month after operations commenced. Prior to twelve full months of operation, Dakota-3 will, at the end of each month, add the emissions for that month toDelores Sand 29-32H Pad 09/30/11 pg. 17 NSR Synthetic Minor Permit Application Project #: WEP211324 

## the calculated emissions for all previous months since operations commenced, where applicable, and record the total. Thereafter, Dakota-3 will, at the end of each month, add the emissions for that month to the calculated emissions for the preceding eleven months and record a new twelve-month total.
Dakota-3, when feasible, may use a Supervisory Control and Data Acquisition (SCADA) system to monitor and record the needed data. SCADA consists of computer systems that monitor and control industrial, infrastructure, or facility-based processes. The system may include, but is not limited to, production monitoring, electronic pressure indicating transmitters, pilot flame status monitoring, valve position setpoints, temperature monitoring, alarm notification, data logging, flowmeter monitoring, etc.Delores Sand 29-32H Pad 09/30/11 pg. 18 NSR Synthetic Minor Permit Application Project #: WEP211324 

# 7.0 QUALITATIVE AIR QUALITY ASSESSMENT

The climatology and air quality of the area of interest is dominated by continental air masses with only minor terrain features (from a synoptic point of view) of interest. The area has excellent ventilation since large air mass movement is not limited by any significant geologic features. This is in stark contrast to other areas in Region 8 that may have limited atmospheric mixing due to mountain valleys or large mountain ranges that can minimize the effect of air mass movement.
Ambient air quality data has been gathered in and near the reservation for many years. The results of that ambient monitoring network indicate ambient concentrations of all pollutants well below the National Ambient Air Quality Standards (40 CFR 50). Those measured values include the impact of substantial oil and gas development that has occurred in the region including development near the proposed facility. In fact, much of the monitoring data yields background values despite the presence of current industrial activity and general anthropogenic sources. The reported data shows that the values are the same or nearly the same as one would find in a rural location devoid of any industrial activity (although industrial activity is clearly nearby).
A typical single well pad facility’s actual emissions are modest in nature (i.e., below typical permitting thresholds); therefore, additional ambient impact analysis is not warranted.Delores Sand 29-32H Pad 09/30/11 pg. 19 NSR Synthetic Minor Permit Application Project #: WEP211324 

# 8.0 ENDANGERED SPECIES ACT

The Endangered Species Act (ESA) requires EPA, in consultation with the U.S. Fish and Wildlife Service (USFWS) and/or the NOAA Fisheries Service, to ensure that actions EPA authorizes are not likely to jeopardize the continued existence of any listed threatened or endangered species (TES) or result in the destruction or adverse modification of designated critical habitat of such species. TES are considered to be those species recognized by the USFWS as listed or proposed species, and those designated as candidate TES under the ESA. Whether critical habitat for TES exists near the facility will first be assessed by consulting the USFWS North Dakota Ecological Service Field Office website ( http://www.fws.gov/northdakotafieldoffice/index.htm ) and noting the potential occurrence of each TES by county. Once the potential presence of a species is assessed, a look at whether any critical habitat exists in the vicinity of the facility will help determine the possibility of any impacts from the facility on TES. EPA will conduct an evaluation of the potential for TES impacts from the facility and consult, as appropriate, with USFWS regarding identification and mitigation of any impacts.Delores Sand 29-32H Pad 09/30/11 pg. 20 NSR Synthetic Minor Permit Application Project #: WEP211324 

# 9.0 NATIONAL HISTORIC PRESERVATION ACT

The National Historic Preservation Act requires EPA, in consultation with State and/or Tribal Historic Preservation Officers, to ensure that actions authorized are not likely to affect cultural resources.
The potential for cultural resources in the vicinity of the facility will be assessed by consulting with the North Dakota State Historic Preservation Office (NDSHPO) and the Tribal Historic Preservation Officer(s), and conducting a literature review of available information from the area immediately surrounding the facility (http://history.nd.gov/hp/siclass1.html). If the review finds a need for more intensive analysis of the immediate area of the facility, a Class II or III cultural resources inventory may be performed as required. EPA will conduct the consultation with NDSHPO and Tribal officials to identify any cultural resources that could be impacted by the facility and any needed mitigation measures for those impacts.Dakota-3 E&P Company, LLC.
