1. Hydrocarbon storage tanks (HSTs) include tanks that store hydrocarbon products and hydrocarbon production waste streams such as, oil production tanks; condensate productions tanks; and slop oil tanks. Produced water tanks at this facility are considered to be HSTs only if they are connected by piping, or by interconnected or common vent lines to other HSTs.

(Requested additional paragraph to Section I.D.3.(a):

I.D.3.(a) Facility – Wide Emission Requirements, Monitoring Requirements “The permittee shall calculate monthly emissi on for each emission source type (tanks, process devices, etc.) using the ratio of: actual production th roughput, operating hours, or other appropriate parameter, divided by the appropria te production parameter value used to calculate the estimated monthly emissions in the permit application. The emission ra tio thus derived will be multiplied by emission value calculated for each source type in the application, to determine the calculated emissions for each month for each source type. “

Requested revised Section I.K.3. :

I.K.3. Requirements for Testing Engines over 500 horsepower

For each engine with a site-rated bhp greater than or equal to 500, the permittee shall conduct an in itial EPA Reference Method performance test within one year of startup, measure VOC emissions. The permittee shall also conduct subsequent performance tests on each engine thereafter, every 8,760 hours of operation or 3 years, whichever comes first. The results of the performance tests shall be used to calculate the actual engine emissions included in the consecutive 12-month facility-wide total.

Requested revised Section I.K.4. :

I.K.4. Requirements for Catalyst-Equipped Engines

For each engine over 500 site-rated horsepower, if equipped with a catalytic control system:

(a) Install, operate, and maintain pressure-sensing devices at the inlet and outlet of the catalyst to measure and record the pressure drop across the catalyst.

(b) Install, operate, and maintain temperature-sensing devices to measure the temperature of the engine exhaust at the inlet of the catalyst.

(c) Measure and record the pressure drop across the catalyst and the temperature of the engine exhaust at the inlet of the catalyst, at least monthly, to ensure that the pressure drop and temperature are maintained within the operating limits specified by the catalyst manufacturer.

Other Requested Changes Revisions:

Other requested changes to permit language include additional items not discussed above, but which were listed or requested under “Technical Clarifi cations” in a letter from the North Dakota Petroleum Council to Mr. Jim Martin, EPA, dated December 7, 2011.

### Process Description

This is a multi-well facility that will separat e production from three (3 ) proposed oil and natural gas exploration and production wells dr illed at this location. Each we ll 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, condens ate and produced water) flows from each well. The well fluids flow to its res pective 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 (condensat e) and produced water flow to their respective storage
tanks.

The natural gas stream fr om the vertical heater treater is expected to be metered into a natural gas sales pipeline. If t he pipeline is not immediat ely available or if it becomes unavailable the natural gas will go to a utility flare.

From the condensate storage tan ks, 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 divert ed to one of the "divert" tanks wh ere it will be tr eated 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 pi pelines 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 pi ping 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 natu ral 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 moto r driven pumping unit, and other facility power
needs.

V OC, Benzene & n-Hexane Emissions

Annualized Production (BPY): 226,300 Control Description: Utility Flare

Production While Controls Operational: 226,300 Control Efficienc y : 98%

Production forecasts are based on the first year of production for similar wells in the area. Production decline was built int o 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 fac ilities pr oduction 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.
