Website Title: Noble Energy Inc. - SLW Ranch B12 Econode T5N-R64W-S12 L02 - Weld County
Notice Period Begins: April 23, 2020
Notice is hereby given that an application for a proposed projector activity has been submitted to the
Colorado Air Pollution Control Division for the following source of air pollution:
Applicant: Noble Energy Inc.
Facility: SLW Ranch B12 Econode T5N-R64W-S12 L02
Oil and gas exploration and production
NESW Sec 12 T5N R64W
Weld County
The proposed project or activity is as follows: Noble is requesting to remove vapor recovery units at an
existing oil and gas exploration and production site and to vent an existing low pressure separator and vapor
recovery tower emissions to flare.
The Division has determined that this permitting action is subject to public comment per Colorado
Regulation No. 3, Part B, Section III.C due to the following reason(s):
• the source is requesting a federally enforceable limit on the potential to emit in order to avoid other
requirements
The Division has made a preliminary determination of approval of the application.
A copy of the application, the Division's analysis, and a draft of Construction Permit 13WE2794 have been
filed with the Weld County Clerk's office. A copy of the draft permit and the Division's analysis are
available on the Division's website at https://www.colorado.gov/pacific/cdphe/air-permit-public-notices
The Division hereby solicits submission of public comment from any interested person concerning the ability
of the proposed project or activity to comply with the applicable standards and regulations of the
Commission. The Division will receive and consider written public comments for thirty calendar days after
the date of this Notice. Comments may be submitted using the following options:
• Use the web form at https://www.colorado.gov/pacific/cdphe/air-permit-public-notices. This page

CDPHE Gas Venting APEN - Form APCD-211
` 'Y Air Pollutant Emission Notice (APEN) and
CDPHE Application for Construction Permit
1M
All sections of this APEN and application must be completed for both new and existing facilities, including APEN
updates. Incomplete APENs will be rejected and will require re-submittal. Your APEN will be rejected if it is filled
out incorrectly, is missing information, or lacks payment for the filing fee. The re-submittal will require payment
for a new filing fee.
This APEN is to be used for gas venting only. Gas venting includes emissions from gas/liquid separators, well head
casing, pneumatic pumps, blowdown events, among other events. If your emission unit does not fall into this
category, there may be a more specific APEN for your source (e.g. amine sweetening unit, hydrocarbon liquid
loading, condensate storage tanks, etc.). In addition, the General APEN (Form APCD-200)is available if the
specialty APEN options will not satisfy your reporting needs. A list of all available APEN forms can be found on the
Air Pollution Control Division (APCD)website.
This emission notice is valid for five (5)years. Submission of a revised APEN is required 30 days prior to expiration
of the five-year term, or when a reportable change is made (significant emissions increase, increase production,
new equipment, change in fuel type, etc.). See Regulation No. 3, Part A, II.C. for revised APEN requirements.

Section 03 - Description of Project
In the October 2019 application, Noble stated they would be removing the VRUs at this site, which recycle the LP separator and VRT gases to sales gas, and would
route the LP gases (as Point 004) to an existing open flare and the VRT gases (new point 016) to a new enclosed flare. After reviewing the previous permit
applications and permit issuances, it appears Point 004 was previously permitted for routing HP separator gas to an open flare. I discussed this issue with Noble.
Noble clarified in an email 3/3/2020 that the HP separator was never vented to the open flare. Thus, they wanted to update the emissions stream composition to
correctly reflect the LP stream. Noble also collected site-specific samples to better understand emissions. These samples and the model are used to estimate
emissions. On March 17, 2020, Noble proposed a different configuration and provided a revised application on 4/1/2020 to permit a new Point 016 for a combined
LP and VRT stream routed to enclosed combustors. On 4/14/2020, Noble informed me they were no longer moving forward with the different configuration and
requested to revert back to the original submittal with the revised model and emissions provided 2/12 and 3/12/2020. On 4/20/2020, Noble requested to increase
the requested throughput for the LP separators and VRT.

Description
Noble used a site-specific liquids sample collected at the outlet of the VRT (Separator Watt-N7-01-SLW0B12, collected 7/24/2013) as the basis for the Promax model. Noble used the " •eversipator" simulation in Promax to
then estimate the inlets to the VRT and then used the "reversipator" again to create the inlet to the low pressure separator. Noble then used the HP liquid stream calculated by the reversipator as an inlet in a different
Promax model that was then based on the expected pressure and temperature for the VRT at this site. The site-specific sample was at a pressure of 5 psig and 75 deg F and was the basis for the reversipator streams. Noble
set up the other Promax model using the calculated HP inlet but with the VRT at a pressure of 4 psig and temperature of 100 deg F. The LP and VRT gas flows and compositions are based on this Promax model. I compared this
model and it was slightly higher than the LP and VRT gas streams modeled by the "reversipator." Since the model a: the expected pressure and temperatures creates higher emissions, I will accept these models as the basis
for the LP and VRT gas flow and composition for requested permit limits. Further, Noble sampled the streams on 3/2/2020 and the sample had slightly higher concentrations for some pollutants. Noble used the higher values
between the model and gas sample results to estimate emissions. Primarily, the HAPs are based on the model and the VOC wt% is based on the gas sample.

Section 07 - Initial and Periodic Sampling and Testing Requirements
Using Gas Throughput to Monitor Compliance 6Gt�. _
Does the company use site specific emission factors based on a gas sample to estimate emissions? .> i . ^3 Sample submitted 3/4/2020
This sample should represent the gas outlet of the equipment covered under this AIRs ID, and should have been collected within one year of the application received date. However, if the facility has
not been modified (e.g., no new wells brought on-line), then it may be appropriate to use an older site-specific sample.
If no, the permit will contain an "Initial Testing Requirement" to collect a site-specific gas sample from the equipment being permitted and conduct an emission factor analysis to demonstrate
that the emission factors are less than or equal to the emissions factors established with this application.
Are facility-wide permitted emissions of VOC greater than or equal to 90 tons per year? Facility emissions are greater than 40 tpy.
If yes, the permit will contain:
-An "Initial Testing Requirement" to collect a site-specific gas sample from the equipment being permitted and conduct an emission factor analysis to demonstrate that the emission factors
are less than or equal to the emissions factors established with this application.
-A "Periodic Testing Requirement" to collect a site-specific gas sample from the equipment being permitted and conduct an emission factor analysis to demonstrate that the emission factors
are less than or equal to the emissions factors established with this application on an annual basis.
Will the operator have a meter installed and operational upon startup of this point? No
If no, the permit will contain a condition that requires the operator to calculate gas throughput using the liquid throughput until the meter is installed and operational (not to exceed 180
days). This condition will use the "Volume of waste gas emitted per BBL of liquids throughput" (scf/bbl) value in section 03.
Does the company request a control device efficiency greater than 95% for a flare or combustion device?
If yes, the permit will contain compliance testing requirements to demonstrate the destruction efficiency of the combustion device based on
inlet and outlet concentration sampling
You have indicated above that the monitored process parameter is natural gas vented. The following questions do riot require an answer.

Section 08 - Technical Analysis Notes
As of Issuance 1 (issued Jun? 12, 2014), this permit has included Point 004 listed in the description as "separator controlled by a flare stack." Point 004 was controlled by an open flare. Based on the gas composit on used for the emission
calculations, the stream appeared to be from a high pressure separator but it's not clearly identified in the permit or )A. With this modification, Noble is clarifying the stream is the low pressure separator stream, revising the gas stream
composition based on modeling and sampling of the LP stream, and decreasing throughput from 65 MMscf/yr to 2 MMscf/yr.
I was concerned this point is new and Noble no longer needs Point 004 for flaring HP gas. I emailed Noble and Janessa Salgado responded via email stating "The purpose of this permit application was to correct historic permitting errors at the
facility. Digging into the history of this facility we never combusted HP gas in the open flare. The HP gas was only sent through HP sales compressors and onto sales. The LP gas was sent through VRU's and when :he VRU's were down to the
open flare. So, this modification is correcting the composition of the gas associated with Point 004." Thus, I will update Point 004 based on the requested flow and revised stream composition.
Noble sampled the stream 3/2/2020 and emailed the results to me. The sampling showed some higher concentratiors, so Noble applied a safety factor of 2.9 to all the pollutants from the modeling to ensure the permitted values are higher
than the sample results. Noble submitted revised emission calculations on 4/20/20 requesting to increase the throughput from 2.0 MMscf/yr to 8.0 MMscf/yr. Noble also requested to use the highest between the model and the sample instead
of applying a safety factor.
Since the wells and separators commenced operation 7/1/2013 and no new wells have been constructed, hydraulicaly fractured, or recompleted on or after August 1, 2014, the separator is still not subject to Reg 7 requirements.

Description
Noble used a site-specific liquids sample collected at the outlet of the VRT (Separator Watt-N7-01-SLWOB12, collected 7/24/2013 ! as the basis for the Promax model. Noble used the "reversipator" simulation in Promax to
then estimate the inlet to the VRT and then used the "reversipator" again to create the inlet to the low pressure separator. Noble then used the HP liquid stream calculated by the reversipator as an inlet in a different Promax
model that was then based on the expected pressure and temperature for the VRT at this site. The site-specific sample was at a pressure of 5 psig and 75 deg F and was the basis for the reversipator streams. Noble set up the
other Promax model using the calculated HP inlet but with the VRT at a pressure of 4 psig and temperature of 100 deg F. The LP and VRT gas flows and compositions are based on this Promax model. I compared this model
and it was slightly higher than the LP and VRT gas streams modeled by the "reversipator." Since the model at the expected pressure and temperatures creates higher emissions, I will accept these models as the basis for the
LP and VRT gas flow and composition for requested permit limits. Further, Noble sampled the streams on 3/2/2020 and the model stream composition is higher than the sample results.

Section 07 - Initial and Periodic Sampling and Testing Requirements
Using Gas Throughput to Monitor Compliance
Does the company use site specific emission factors based on a gas sample to estimate emissions? _ , ^:,`4; „0$ Sample submitted 3/4/2020
This sample should represent the gas outlet of the equipment covered under this AIRs ID, and should have been colleted within one year of the application received date. However, if the facility has
not been modified (e.g., no new wells brought on-line), then it may be appropriate to use an older site-specific sample.
If no, the permit will contain an "Initial Testing Requirement" to collect a site-specific gas sample from the Equipment being permitted and conduct an emission factor analysis to demonstrate
that the emission factors are less than or equal to the emissions factors established with this application.
Are facility-wide permitted emissions of VOC greater than or equal to 90 tons per year? Yes Facility emissions are greater than 40 try.
If yes, the permit will contain:
-An "Initial Testing Requirement" to collect a site-specific gas sample from the equipment being permitted and conduct an emission factor analysis to demonstrate that the emission factors
are less than or equal to the emissions factors established with this application.
-A "Periodic Testing Requirement" to collect a site-specific gas sample from the equipment being permittec and conduct an emission factor analysis to demonstrate that the emission factors
are less than or equal to the emissions factors established with this application on an annual basis.
Will the operator have a meter installed and operational upon startup of this point? N
If no, the permit will contain a condition that requires the operator to calculate gas throughput using the li iuid throughput until the meter is installed and operational (not to exceed 180
days). This condition will use the "Volume of waste gas emitted per BBL of liquids throughput" (scf/bbl) valLe in section 03.
Does the company request a control device efficiency greater than 95% for a flare or combustion device?
If yes, the permit will contain compliance testing requirements to demonstrate the destruction efficiency of the combustion device based on
inlet and outlet concentration sampling
You have indicated above that the monitored process parameter is natural :as vented. The following questions do not require an answer.

Section 08 - Technical Analysis Notes
Noble had submitted a pressurized liquids sample from the VRT outlet and model to estimate emissions. On 3/4/2020, Noble submitted a sample of the VRT gas stream collected 3/2/2020 which showed the modeled stream composition as
slightly higher for VOC and HAPs. Thus, no initial sample will be required and the model will be used as the basis for establishing permit limits. Emissions are based on the final application provided 4/20/2020.
