### Process Description

This is a multi-well facility t hat will separate producti on from four (4) 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.

### Condensate Storage Tank Emissions Calculations

VOC, Benzene & n-Hexane Emissions

Annualized Production (BPY): 301,730 Control Description: Utility Flare

Production While Controls Operational: 301,730 Control Efficiency: 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 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).

Permission was acquired to survey the site from the allottees and BIA and the required NEPA/EA

Process commenced. Environmental on

‐ site surveys are currently being performed (BIA, Site survey, Biology, Archeology, Tribal historic preservation, Company Rep.) for AVOID, MOVE, and MITIGATE

consideration. The environmental on

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 submits 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. If 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 scoping period for the FONSI begins.

If no unresolved issues are raised during the 30

‐ day public scoping 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 or development of the

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