Instructions 

Use 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.

Criteria Pollutant Emissions Estimates 

 Estimates of Current Actual Emissions, Current Allowable Emissions, Post-Change Uncontrolled 

Emissions, and Post-Change Allowable Emissions for the following air pollutants: particulate 

matter, PM10, PM2.5, sulfur oxides (SOx), nitrogen oxides (NOx), carbon monoxide (CO), volatile 

organic compound (VOC), lead (Pb) and lead compounds, ammonia (NH3), fluorides (gaseous and 

particulate), sulfuric acid mist (H2SO4), hydrogen sulfide (H2S), 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 any 
Page 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.

 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 4th criteria 

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

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.htm. 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

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.

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 of America 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 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 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 of specific pollutants. In that 
Page 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 CO2e and 100 or 250 tpy on a mass basis, modifications at existing PSD facilities that increase 

GHG emissions by at least 75,000 tpy CO2e and minor sources that increase GHG emissions by at least 

100,000 tpy CO2e 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 CO2 equivalents (CO2e), the mass emissions of each individual GHG

NSR Synthetic Minor Permit Application 

Project #: WEP211324

1.0 INTRODUCTION 

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 Patricia Kelly 2-1H 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 Patricia Kelly 2-1H Pad is proposed to be located in the southwest 1⁄4 of the 

sothwest 1⁄4 Section 2, Township 150 North, Range 94 West, McKenzie County, on the 

FBIR in North Dakota. 

1.3. Site Description 

 

At the proposed Patricia Kelly 2-1H Pad there will be four 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 McKenzie 

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

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

1. Patricia Kelly 2-1HZ 

2. Patricia Kelly 2-1HC 

3. Patricia Kelly 2-1HD 

4. Patricia Kelly 2-1HX 
Patricia Kelly 2-1H Pad 09/30/11 pg. 2

Project #: WEP211324

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.

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 

Patricia Kelly 2-1H Pad. For purposes of estimating emissions from this facility, the 

combined first twelve-month potential production from the four 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. 

4 - Heater Treater/Separators 4 - Line-Heaters (0.75 MMBtu/hr max) 

16 - Oil Production Tanks 1 - Gasoline Recycling Pump 

4 - Produced Water Tanks 4 - Electric Lifting Units 

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

1 - Manufactured Produced Gas Flare 4 - Diesel Engines 

1 - Manufactured Enclosed Tank Vapor Combustor 4 - LACT Units 

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

wellbore 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 
Patricia Kelly 2-1H Pad 09/30/11 pg. 4 

NSR Synthetic Minor Permit Application 

Project #: WEP211324

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. 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.

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 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 

Patricia Kelly 2-1H Pad 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 rolling 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.

Project #: WEP211324

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 (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 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 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 pipeline 
Patricia Kelly 2-1H Pad 09/30/11 pg. 9 

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 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 IIII 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 lineheaters. Each 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 hooked 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.

4.0 EMISSIONS AND OPERATIONAL LIMITS REQUESTS 

Datoka-3 is requesting emissions and operational limits at the Patricia Kelly 2-1H 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: 20.75 tons per year of VOCs and 0.29 tons per year of HAPs. 

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.

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, PM10, PM2.5 

and N2O 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.

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 fugitive 

emissions 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 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/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. 
Patricia Kelly 2-1H Pad 09/30/11 pg. 14 

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 

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 VOC (or VOC 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 °C, or ±2.5 °C; 

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 flame fails; 

f. Maintained in a leak-free condition; and 

g. Operated in a smokeless mode.

analysis or provide a manufacturer or vendor guarantee; and 

e. Visually confirm that no smoke is present during operation of any enclosed 

combustor or utility flare whenever an operator is on site; at a minimum, 

quarterly. 

Recordkeeping Requirements: 

a. Records will be kept of the site-specific design input parameters provided for the 

independent engineering analysis or provided to the manufacturer or vendor and 

used to properly size the enclosed combustors and utility flares to assure the 

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 

increase the operating time of the pilot flame. 

f. Records will be kept of any instances in which the thermocouple (or other heat 

sensing monitoring device) installed to detect the presence of a flame in the 

enclosed combustor or utility flare is not operational, the time period during which 

it was not operational, and the corrective measures taken.

combustor or utility flare whenever an operator is on site; at a minimum, 

quarterly. 

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. 

6.3 Produced Casing Head Gas Emergency Utility Flare 

Dakota-3 is not requesting any limits from the produced casing head gas because it is 

being sent to the gas sales pipeline. If a malfunction from the pipeline occurs and the 

gas cannot be sold, Dakota-3 will record the volume of gas sent to the emergency utility 

flare. 

During an emergency or malfunction Dakota-3 will route the produced casing head gas 

to the onsite utility flare that will be designed and operated to reduce the mass content 

of VOC (or VOC and HAP) emissions in the vapors vented to the device by at least 

98%. Dakota-3 will follow, for the 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 utility flare will be 

maintained and operated during any time the facility is operating. 
Patricia Kelly 2-1H Pad 09/30/11 pg. 17 

NSR Synthetic Minor Permit Application 

Project #: WEP211324

The emergency utility flare will be: 

a. Designed and operated in accordance with the requirements of 40 CFR 60.18 

and 40 CFR 63.11. 

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

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

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

d. 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 °C, or ±2.5 °C;

described above for the production storage tanks control device as specified in Section 

6.2. 

Recordkeeping Requirements: 

The recordkeeping requirements for the emergency utility flare will be the same as 

described above for the production storage tanks control device as specified in Section 

6.2. 

6.4 RICE Engines 

Depending on the size (hp) and date of manufacture, Dakota-3 is required to meet the 

emission standards set forth in 40 CFR 63 Subpart JJJJ or 40 CFR 60 Subparts IIII and 

ZZZZ, as applicable. 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-heaters, no monitoring or recordkeeping requirements are being 

proposed by Dakota-3. 
Patricia Kelly 2-1H Pad 09/30/11 pg. 18 

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. Method 21 

a) Use the equipment leak detection methods in 40 CFR Part 60, 

Appendix A–7, Method 21; and 
Patricia Kelly 2-1H Pad 09/30/11 pg. 19 

NSR Synthetic Minor Permit Application 

Project #: WEP211324

b) If an instrument reading of 10,000 ppm or greater is measured, a leak 

is detected. 

ii. Optical Gas Imaging Instrument 

a) Use an optical gas imaging instrument for equipment leak detection in 

accordance with 40 CFR Part 60, Subpart A, §60.18(i)(1) and (2) of the 

Alternative work practice for monitoring equipment leaks; 

b) Any emissions detected by the optical gas imaging instrument are a 

leak unless screened with Method 21 (40 CFR Part 60, Appendix A–7) 

monitoring, in which case 10,000 ppm or greater is designated a leak; 

c) The optical gas image will include an image of the equipment in 

addition to any observed leaks; and 

d) The optical gas imaging instrument will be operated in accordance with 

the instrument manufacturer’s operating parameters. 

iii. Operator Developed Inspection Protocol - Best Management Practices 

a) Develop and use a written inspection protocol approved by EPA, 

based on best management practices, for leak detection; 

b) Any emissions detected by the protocol are a leak unless screened 

with Method 21 (40 CFR Part 60, Appendix A–7) monitoring, in which 

case 10,000 ppm or greater is designated a leak; 

c) The protocol will include the following: 

I. A detailed description of the best management practice to be 

used for leak detection; 

II. A requirement to use a log book that contains a list, summary 

description, or diagram showing the location of all equipment in 

hydrocarbon service at the facility, and the required 

recordkeeping for equipment leaks; and 

III. A requirement that the log book be signed by the inspector at the 

completion of each inspection. 

Recordkeeping Requirements: 

a. Dakota-3 will document and maintain a record of each leak detection inspection 

and repairs. 

b. All leak detection inspection records will include, at a minimum, the following 

information: 

i. Date of the inspection; 

ii. All documentation and/or images produced in the inspection; 

iii. Findings of the inspection; 

iv. Any corrective action taken; and 

v. Inspector's name and signature. 

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 
Patricia Kelly 2-1H Pad 09/30/11 pg. 20 

NSR Synthetic Minor Permit Application 

Project #: WEP211324

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 (i.e., 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 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.

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.
