One (1)Triethylene glycol (TEG)natural gas dehydration unit
(make, model, serial number to be determined)with a design
capacity of 12.0 MMscf per day. This emissions unit is equipped
with two (2) Kimray, model 21015 gas-glycol pumps with a design

GENERAL TERMS AND CONDITIONS
36. This permit and any attachments must be retained and made available for inspection upon
request. The permit may be reissued to a new owner by the APCD as provided in AQCC
Regulation No. 3, Part B, Section II.B upon a request for transfer of ownership and the
submittal of a revised APEN and the required fee.
37. If this permit specifically states that final authorization has been granted,then the remainder
of this condition is not applicable. Otherwise,the issuance of this construction permit does
not provide"final"authority for this activity or operation of this source. Final authorization of
the permit must be secured from the APCD in writing in accordance with the provisions of
25-7-114.5(12)(a) C.R.S. and AQCC Regulation No. 3, Part B, Section III.G. Final
authorization cannot be granted until the operation or activity commences and has been
verified by the APCD as conforming in all respects with the conditions of the permit. Once
self-certification of all points has been reviewed and approved by the Division,it will provide
written documentation of such final authorization. Details for obtaining final authorization
to operate are located in the Requirements to Self-Certify for Final Authorization
section of this permit.
38. This permit is issued in reliance upon the accuracy and completeness of information
supplied by the owner or operator and is conditioned upon conduct of the activity, or
construction, installation and operation of the source,in accordance with this information and
with representations made by the owner or operator or owner or operator's agents. It is valid
only for the equipment and operations or activity specifically identified on the permit.
39. Unless specifically stated otherwise, the general and specific conditions contained in this

provisions of Section 25-7-114.5(7)(a), C.R.S.
40. Each and every condition of this permit is a material part hereof and is not severable. Any
challenge to or appeal of a condition hereof shall constitute a rejection of the entire permit
and upon such occurrence,this permit shall be deemed denied ab initio. This permit may be
revoked at any time prior to self-certification and final authorization by the Air Pollution
Control Division (APCD) on grounds set forth in the Colorado Air Quality Control Act and
regulations of the Air Quality Control Commission (AQCC), including failure to meet any
express term or condition of the permit. If the Division denies a permit, conditions imposed
upon a permit are contested by the owner or operator,or the Division revokes a permit,the

Point Description
One(1)Tdethylene glycol(TEG)natural gas dehydration unit(make.model,serial number to be determined)with a design capacity of 12.0 MMscf per day.This
emissions unit is equipped with two(2)Kimray.model 21015 gas-glycol pumps(one pump serves as a back-up)with a design capacity of 3.5 gallons per minute.This
unit is equipped with a flash tank,reboiler and still vent.Emissions from the still vent are routed to an air-cooled condenser and then to the flare.Emissions from the
gash tank are 100%recycled to the sales gas line or to the fuel gas system.
Emissions Calculation Review
The source used GRI Glycalc 4.0 to estimate emissions.The Glycalc run was based on a weighted average of extended wet gas analyses collected 11/20/2014 from
North Platte 14-36 and 11/20/2014 from North Platte X-D-35HZ.The model was based on the following parameters:
Inlet Gas Pressure 814.7 psis
Inlet Gas Temperature 120 deg F

Regulatory Review
Regulation 3
Part A APEN Requirements
APEN is required since emissions are greater than 1 tpy VOC.
Part B-Construction Permit Requirements
Permit is required since facility-wide VOC emissions are greater than 2 toy
Regulation 7-Volatile Organic Compounds
XII.H VOLATILE ORGANIC COMPOUND EMISSIONS FROM OIL AND GAS OPERATIONS
Applicant is subject to the emission control requirements for glycol dehydrators since it is located in the nonattainment area and uncontrolled actual VOC emissions are
greater than 15 IpY
XVII.D STATEWIDE CONTROLS FOR OIL AND GAS OPERATIONS
Per Reg 7.Section XVII.6.5,dehydrators subject to an emission control requirement under 40 CFR Part 63 are exempt from Section XVII.However,as discussed
below in MACT HH.this deny is not subject to a control standard under MACT because it is meeting an emission exemption.Thus,the deny is still subject to Regulation
7 XVII requirements.
Applicant is currently subject to XVIII.0.2 because actual uncontrolled VOC emissions are greater than 15 toy.
Applicant is currently subject to XVII.0.3 and XVII.D.4.a because the dehydrator will be constructed after 5/1/2015 and uncontrolled actual emissions of VCC are greater
than 2 tpy.
Regulation 8-Control of HAPs
Part E-MACT HH
Since this facility is an oil and gas exploration and production facility,it qualifies as a production field facility as defined in MACT HH_As a production field facility,only
dehys and storage vessels with flash are included when determining major source status.This production field facility is a synthetic minor source of HAPs and is then
an area source of HAPs per MACT HH.This TEG dehy is subject to MACT HH area source requirements.However,the dehy will be able to comply with the exemption
by maintaining actual benzene emissions to less tan 1984 lb/yr.This source is only required to calculate and keep records demonstrating that benzene emissions stay
below the exemption threshold.
