Process Description

This is a multi-well facility that will separate production from two (2) proposed oil and natural 

gas exploration and production wells drilled at this location. Each well will flow to its respective 

process equipment; this equipment is similar in construction and function. The typical process 

train is described below. 

The commingled fluid stream (containing natural gas, condensate and produced water) flows 

from each well. The well fluids flow to its respective 6' x 20' vertical heater treater (0.5 

MMBtu/hr burner duty rating). In this vertical treater, the fluid is heated to a desired 

temperature range to aid in separation of the condensate, natural gas and produced water. 

The hydrocarbon liquid (condensate) and produced water flow to their respective storage 

tanks. 

The natural gas stream from the vertical heater treater is expected to be metered into a natural 

gas sales pipeline. If the pipeline is not immediately available or if it becomes unavailable the 

natural gas will go to a utility flare. 

From the condensate storage tanks, the condensate is metered through a L.A.C.T. (Lease 

Automated Custody Transfer) unit and is sold as it is pumped, using electric motor driven 

pumps, into a condensate sales pipeline. If the condensate does not meet sales quality 

standards it is automatically diverted to one of the "divert" tanks where it will be treated until it 

can meet sales specifications and be sold. 

The produced water uses electric motor driven water transfer pumps to pump the produced 

water to a centralized water handling facility for disposal. 

The hydrocarbon vapors from all of the storage tanks are sent to a utility flare through a 

common tank piping system. 

If conditions do not allow the use of the pipelines to transport the produced water or 

condensate, then the liquids will be loaded into tanker trucks and hauled from the facility. 

There are fugitive emissions associated with the piping connections, flanges, valves, etc. 

These emissions occur due to the potential seeping of gas from connections, seats, and seals. 

A trailer mounted dual fueled (diesel and natural gas) engine driven generator will be utilized 

for facility power until utility power is available. This generator will supply the power necessary 

to operate the LACT pumps, an electric motor driven pumping unit, and other facility power 

needs.

NOTES:

a - Condensate tanks emissions estimated using the process simulation software BR&E ProMAX and a like kind pressurized condensate analysis (Rupple).

b - Divert tanks are used only during upset conditions (i.e., when condensate does not meet sales specifications), quantification of emissions is not required.c - Produced water tank vent lines are connected to the condensate tank vent system and accounted for at source (001) "Condensate Storage Tanks". Produced water is not

 an emission source but the small amount of condensate that carries over in the water is the source of emissions, condensate tank emissions account for all of these emissions.

d - Burner emissions based on EPA AP-42 emission factors from Section 1.4, Tables 1.4-1 and 1.4-2 for uncontrolled natural gas burners (July 1998), the worst case assumption

 that burners operate 8,760 hours per year and a fuel heating value of 1430 Btu/SCF.e - Heater Treater uncontrolled vent (casing head gas) VOC and HAP emissions represent a worst-case scenerio in which casing head gas does not go to pipeline.f - Generator engine emissions are estimated using 150 Hp diesel fueled tier II engine emission factors. These engines are trailer mounted and are expected to be portable. 

 Engine emissions have been listed here to ensure that all emissions sources have been identified due to uncertainty of when utility power will be available.

g - Truck loadout emissions were based on worst case assumption that produced liquids will be trucked from the facility year round, due to uncertainty of pipeline.h - Fugitive component type and count is an estimate, the emissions were calculated using EPA Table 2-4 for E&P production facilities.

VOC, Benzene & n-Hexane Emissions

Annualized Production (BPY): 150,870 Control Description: Utility Flare

Production While Controls Operational: 150,870 Control Efficiency: 98%

Production forecasts are based on the first year of production for similar wells in the area. Production decline was built into the

annualized total.

VOC lb/bbl was calculated using BRE Promax software and a representative pressurized liquid analysis (Rupple).

Production while controls operational represents the portion of this facilities production where the tank emissions were

controlled.

NOx and CO emission factors were taken from Table 4 of the Texas Natural Resource Conservation Commission's (TNRCC) 

"Air Permit Technical Guidance for Chemical Sources - Flares and Vapor Oxidizers" document. The waste gas stream is assumed

to be high-Btu (> 1,000 Btu/scf).

Other Requested Data

1. Field natural gas is used as fuel for the burners associated with the vertical heater

treaters. The quanitity of natural gas used varies due to fuel consumption being 

regulated by a thermostat.

2. This facility typically operates 24 hours per day, 7 days a week, 52 weeks a year.

3. The only emission control anticipated for use at this facility is an enclosed flare or 

utility flare.

4. Air dispersion modeling is not being supplied with this application. This facility

is located in an attainment area, in an undeveloped area of the Fort Berthold

Reservation. The potential impacts from this facility should not require air

dispersion modeling.

Permit Application 14‐32B   

Permission to survey the site has been requested from the allottees and BIA and the required

NEPA/EA Process has commenced.  Survey permission is anticipated to be granted during May 2012.

As soon as permission is granted, environmental on‐site surveys will be performed (BIA, Site survey,

Biology, Archeology, Tribal historic preservation, Company Rep.) for AVOID, MOVE, and MITIGATE

consideration.     

After the above surveys/studies are completed, the Third Party consultant (TP) will submit the

Solicitation of View (SOV) letter to all affected Agencies, at which time the 30‐day SOV comment

period will begin.   

After the 30‐day SOV comment period closes, the TP will submit a draft EA to the BIA, taking into

account comments received during the SOV period.  The BIA Regional Office will review the Draft EA

and SOV comment letters, and recommend any required revisions of the EA to the TP.  After any and

all issues raised during the SOV/draft EA process are resolved, a FONSI will be issued and signed by

BIA, after which the 30‐day public comment period for the FONSI begins.    

   

If no unresolved issues are raised during the 30‐day public comment period, and if all the allottee

signatures are in place, BIA will approve and transmit the FONSI to the permittee.    

No permits from BIA and/or BLM will be issued and no disturbance of the site or construction of the

referenced facility can commence until all steps in the above process are completed, a signed FONSI

is transmitted to the permittee, and all related approvals are obtained from BLM/BIA.
