Instructions 

Use of This Form 

• 	 Proposed new construction or modifications should first be evaluated to determine ifthe change is 

major under the major NSR program using the procedures at 40 CFR 52.21 (Le., baseline actual to 

projected actual applicability test). Ifthe proposed construction does not qualify as a major under 

that test, then it may be subject to the requirements ofthe 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. J 52(d) - Modification means any physical or operational change at a source that would 

cause an increase in the allowable emissions ofthe affected emissions units for any regulated NSR 

pollutant or that would cause the emission ofany 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 ofoperation 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.J52(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 ofa stationary source calculated 

using the maximum rated capacity ofthe source (unless the source is subject to federally 

enforceable limits which restrict the operating rate, or hours ofoperation, or both) and the most 

stringent ofthe 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.

• 

2. The information should include all ofthe 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/ttnichief/eipac/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 ofhours in a year) and dividing 

by 2,000 (which is the number ofpounds 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 ofsuch 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 ofhours in a year) and dividing by 2,000 (which is the 

number ofpounds in a ton). 

1. 	 "Allowed" means the source is restricted by permit conditions that limit its emissions and are 

enforceable as a practical matter (Le., allowable emissions). The allowable emissions for any 

Page 1\ 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 ofhours in a year) and 

dividing by 2,000 (which is the number ofpounds 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 

(lbslhr) times allowed hours (which is the number ofhours in a year) and dividing by 2,000 (which 

is the number ofpounds 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 offollowing: 

• 	 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 ofthe 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. Ifthe allowable emissions ofan 

emissions unit would be reduced as a result ofthe 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 ofthe 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. Ifthe 

allowable emissions ofan emissions unit would be reduced as a result ofthe change or 

replacement, use zero in the calculation.

• ./ Modeling Analysis 

Do I need to do a modeling analysis? 

The Federal Minor New Source Review Regulations at 40 CFR 49. 1 59(d) requires that a modeling 

analysis (AQIA) ofproposed emissions be performed ifthere is reason to be concerned that new 

construction would cause or contribute to a National Ambient Air Quality Standard (NAAQS) or 

Prevention ofSignificant Deterioration (PSD) increment violation. 

In addition, ifthe 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 ofthe NAAQS and PSD Increment, EPA Region 8 requests that those 

proposed activities that meet the following criteria perform an AQIA: 

I. 	 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 ofthe environmental impact ofthe activities proposed. 

2. 	 Modeling ofproposed 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 ofthe 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) Ifyou have questions about whether modeling may be necessary based on the 4th criteria 

above, please contact EPA Region 8's Modeling Lead:

What Kind ofAir Quality Modeling Analysis Is Needed? 

1. 	 EP A Region 8 considers a stepped or phased approach to modeling to be appropriate, as 

follows: 

Step I: Qualitative Air Quality Assessment 

Step 2: Screening Modeling Analysis 

Step 3: Preliminary Modeling Analysis (refined modeling) 

Step 4: Full Impact Modeling Analysis (refmed modeling) 

Step 5: PSD Increment and NAAQS Analysis 

Step 6: Additional Impact Analysis 

2. 	 Step 1: Qualitative Air Quality Assessment 

Narrative description ofthe 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. 

Ifa 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 ofair quality from proposed emissions may be shown by using a simple

Instructions 

Use 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 ofAmerica or other lands as specified in 40 CFR part 49, collectively 

referred 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 ofthe 

facility taking into consideration the capacity and configuration ofthe equipment and operations. 

Emission or operational limits can also be taken into consideration as maximums ifthey 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 offederal Clean Air Act programs that use PTE to detennine whether they apply are 

(I) the Prevention ofSignificant 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 defmed in that rule as "major") must apply for a Title V operating permit. 

Ifa 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 ofthe 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 ofa 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 fonn for each requested 

limitation. 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 ofspecific pollutants. In that 

• 

Page 2 of4 
• 

case, all emissions units at a facility and all pollutants regulated by that given rule or regulation must 

be addressed by this section ofthe 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, ifapplicable, 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 ofair 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. (ie., 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 ofhours in a year) and dividing by 2,000 (which is • 

the number ofpounds in a ton). 

Item 5 - New construction projects that have the potential to emit GHG emissions ofat least 100,000 

tpy C02e and 100 or 250 tpy on a mass basis, modifications at existing PSD facilities that increase 

GHG emissions by at least 75,000 tpy C02e and minor sources that increase GHG emissions by at least 

100,000 tpy C02e and 100 or 250 tpy on a mass basis are subject to PSD permitting requirements, even 

ifthey 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 ofthe potential emissions ofthe 

following pollutants before and after proposed emission controls. More information about GHG 

permitting and how to calculate CO2 equivalents (C02e), the mass emissions ofeach individual GHG

1.1. Summary 

Dakota-3 E&P Company, LLC (Dakota-3) is submitting this application for a Prevention 

of Significant Deterioration (PSD) and/or Part 71 Title V (Title V) synthetic minor permit 

to the Environmental Protection Agency (Agency) in accordance with the Federal Minor 

New Source Review (NSR) Rule (40 CFR 49) adopted pursuant to the Federal Clean 

Air Act. 

• 

Dakota-3 is proposing to construct and operate the Owl Comes Out 7 -9H Pad 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 and/or Title 

V major source thresholds. These limits can be found in Section 4.0 of the application. 

1.2. Site Location 

The Owl Comes Out 7 -9H Pad is proposed to be located in the northwest % of the 

southwest % Section 17, Township 150 North, Range 91 West, Mountrail County, on 

the FBIR in North Dakota. 

1.3. Site Description 

At the proposed Owl Comes Out 7 -9H Pad there will be six oil and gas wells that are 

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 Mountrail 

County, North Dakota. The surrounding area is mainly used for agriculture and livestock 

grazing. The proposed pad's associated well names are: 

1. Owl Comes Out 7 -9HA 

2. Owl Comes Out 7-9HB 

3. Owl Comes Out 7 -9HD 

• 

4. Owl Comes Out 7 -9HX 

5. Owl Comes Out 7-9HY 

6. Owl Comes Out 7 -9HZ 

The names of the wells may be subject to change due to landowner requirements, 

drilling location changes, timing of well leases, etc. The Agency will be notified if the 

names change.

2.0 NARRATIVE DESCRIPTION 


This section of the application provides a detailed description of the operations at the 

Owl Comes Out 7-9H Pad. For purposes of estimating emissions from this facility, the 

combined first twelve-month potential production from the six proposed wells at this 

facility was used. These production rates can be found in Attachment B, Emission 

Inventory. 

The production rates used in this application are grossly overestimated when compared 

to the actual predicted production rates in the first and subsequent years. The wells that 

will be producing to this facility do not begin producing at the same time. In reality, there 

will be up to six or more years' difference in when the initial production from wells begin 

to when the final wells are constructed and begin to produce. It is not physically possible 

for all of the wells to be simultaneously drilled and begin initial production. However, to 

allow for reasonable flexibility and to be conservative, this application has considered a 

maximum potential production case from the pad. Due to ever-changing drilling 

schedules, completion schedules, economics, etc., the wells will begin actual production 

at different times. 

The entire pad facility will consist of the following primary production equipment and 

capabilities. 

6 - Heater Treater/Separators 6 -line-Heaters (0.75 MMBtu/hr max) 

30 - Oil Production Tanks 1 - Gasoline Recycling Pump 

12 - Produced Water Tanks 6 - Electric Lifting Units 

6 - Oil and Gas Producing Wells 1 - Truck Loading Rack 

1 - Manufactured Produced Gas Flare 6 - Diesel Engines 

1 - Manufactured Enclosed Tank Vapor Combustor 

The oil/gas/water emulsion being produced from the wells is transported up each 

weIIbore using an electric lifting unit. The emulsion from the wells producing to this site 

is transported in a closed system to individual two-phased separators and then to the 

three-phase separators (heater treaters). 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 treaters then reduce the pressure closer to ambient pressure and 

heat 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 separators 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 transported for sale via the truck loadout. Produced water is 

stored in the onsite water storage tank until it is transported otfsite 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 recyde 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. Onsite diesel 

genset engines will provide electricity until transmission lines are installed. 

A process flow diagram and plot plan of the site is shown in Attachment H.

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 each 

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. 

As noted in Section 2.0 above, determination of potential emissions from the proposed 

facility has been approached in a very conservative fashion. The combined production 

rate for the pad assumes all of the wells start production simultaneously (represented in •

example Figure 1). With this assumption, the initial 30-day production from each well is 

summed to estimate a potential total production rate from the pad. Operating practice is 

that the wells will be drilled over time, often months or even years apart. Further, after 

each well is drilled and brought into production, the initial production rate generally 

decreases greatly before the next well is drilled. Therefore, this potential to emit (PTE) 

estimate is meant only to define an outer envelope of emissions for permitting 

applicability purposes. Furthermore, the allowable emissions estimates presented in 

Section 4 are also very conservative compared to anticipated actual emissions that 

could be emitted at the facility during any given 12-month rOiling average. An example 

demonstrating the predicted production of a theoretical multiple well pad over an 

extended period of time is presented in Figure 2. This example does not represent 

predicted production from the well pad being permitted in this application; however, it 

does serve to demonstrate typical operations for this type of facility.

Potential emissions from this facility originate primarily from the heater treater lineheaters 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 engines and 

natural gas-fired external combustion units, 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 (Le., 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 Gensets) 

4. 	 Natural Gas External Combustion Units (Heater Treater Line-Heaters); 

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 rnol% 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 pipeline

• 
• 

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 Engines 

Diesel engines connected to generators provide the facility with electricity. The potential 

emissions from the engines 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 "" and ZZZZ emission limits as applicable. 

3.4 Natural Gas External Combustion Unit Emissions 

The natural gas external combustion units at the facility are the heater treater line­ • 

heaters. Each heater is rated to a maximum capacity of 750,000 Btulhr. The emissions 

are based on AP-42 factors and assume the heater is running 8,760 hours per year. 

3.5 Truck Loading Emissions 

Oil sales and water pipelines are planned for this facility in the future; however, since 

the pipeline infrastructure has not yet been constructed, the facility is not anticipated to 

be hooked to the oil sales pipeline in the near future, and the produced oil and water will 

be trucked from the facility. The emissions associated with the truck loading operations 

will be estimated using daily production, AP-42 factors, and submerged fill loading 

without any control. 

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.

4.0 EMISSIONS AND OPERATIONAL LIMITS REQUESTS 


Datoka-3 is requesting emissions and operational limits at the Tracy 15H 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 PSDfTitie V major source thresholds of 250/100 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 (ORE). 

Although this control device is certified to meet 99% ORE. Oakota-3 will assume the 

minimum required 98% ORE for purposes of calculating the controlled tank vapor 

emissions. This control device will allow Oakota-3 to apply a 98% control efficiency to 

the uncontrolled PTE. On this basis, the requested emission limit from the storage tanks 

is: 28.01 tons per year of VOCs and 0.26 tons per year of HAPs. 

4.2 Reciprocating Internal Combustion or Compression Ignition Engines 

Oakota-3 will be required to limit the emissions from any reciprocating intemal 

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 

1111 and zzzz., as applicable.

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 CH4 emissions. Although the VOC, HAP, and CH4 

emissions are reduced by the smokeless combustion device, CO, NOx• PM, PM1Q, PM2.5 •

and N20 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 pipeline 

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. 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 units (0.5-0.75 

MMBtu/hr heater treater line-heaters) at the facility; therefore, the emissions estimate is 

equal to the uncontrolled potential to emit.

5.5 Truck Loading Emissions 

No limits have been requested for the truck loading operations at the facility; therefore, 

the emissions estimate is equal to the uncontrolled potential to emit. 

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 fugitive 

emissions will be estimated after a final permit is issued in order to track 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 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 gensets. 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.

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/workinglbreathing 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.

• 


Recordkeeping Requirements: 

In order to demonstrate compliance with the 12-month rolling emission limits for the oil 

production tanks, Dakota-3 will track facility oil production rates for each month, 

beginning with the first full calendar month after operations commenced. The monthly 

totals will be summed to create a production rate for the prior twelve month rolling 

operating period. As demonstrated in Attachment C of this application, the total voe, 

total HAP, and any single HAP emissions in tons per year are directly proportional to the 

production rate of oil at the facility. Based upon this relationship, compliance with the 

requested limits in this application will have been maintained if the production rate 

during any twelve month rolling period is less than the production rate used to establish 

the emission limits. 

• 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 

The limits requested on the emissions from the storage tanks are directly dependent on 

the production throughput in the tanks. All emissions at the facility will be controlled in 

one or more enclosed combustors and/or utility flares that are designed and operated to 

reduce the mass content of voe (or voe and HAP) emissions in the vapors vented to 

the device by at least 98%. 

Dakota-3 will follow, for each enclosed combustion device and utility flare, the 

manufacturer's written operating instructions, procedures and maintenance schedule to 

ensure good air pollution control practices for minimizing emissions. 

All vent lines, connections, fittings, valves, relief valves, or any other appurtenance 

employed to contain and collect vapors and transport them to the enclosed combustor, 

or utility flare will be maintained and operated during any time the facility is operating. 

Each enclosed combustion device will be: 

• 	 a. Designed to have sufficient capacity to achieve at least a 98% destruction 

efficiency for hydrocarbon volumetric flow and BTU content routed to the device; 

b. 	 Operated with a liquid knock-out system to condense any condensable vapors; 

c. 	 Equipped with a thermocouple to detect the presence of a pilot flame with a 

minimum accuracy of ±2 percent of the temperature being monitored expressed 

in °e, or ±2.5 °e; 

d. 	 Equipped with a recording device, such as a chart recorder or similar device, to 

document the presence of a flame; 

e. 	 Equipped with an electronically controlled ignition system with a malfunction 

alarm and remote notification system if the pilot 'name fails; 

f. 	 Maintained in a leak-free condition; and 

g. 	 Operated in a smokeless mode.

98% reduction requirements. 


b. 	 Records will be kept of all required monitoring of the control device operations. 

c. 	 Records will be kept of any instances in which any control device was bypassed 


or down in each calendar month, the reason for each inCident, its duration, and 


the corrective actions taken or the preventative measures adopted to avoid such 


bypasses or downtimes. 


d. 	 Records will be kept of the any exceedance of the operating parameters 

specified in the manufacturer or vendor guarantee or engineering analysis and 

selected for the required monitoring. The records will include the enclosed 

combustor's total operating time during the calendar month in which the • 

exceedance occurred, the date, time and length of time that the parameters were 

exceeded, and the corrective actions taken or the preventative measures 

adopted to operate the facility within that operating parameter. 

e. 	 Records will be kept of any instances in which the pilot flame is not present in the 


enclosed combustor or the utility flare, the date and times that the pilot was not 


present and the corrective actions taken or the preventative measures adopted to

• Total VOC (orVOC, 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 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, 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.

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 facility's actual emissions are modest in nature (Le., below typical permitting 

thresholds) as demonstrated in Figure 2: therefore, additional ambient impact analysis 

is not warranted.

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 detennine the possibility of any impacts from the facility on TES. EPA will conduct

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.
