Notice of a Proposed Construction Permit Warranting Public Comment
COPHE
Website Title: PDC Energy, Inc - Market Federal 18 Sec HZ - Weld County
Notice Period Begins: December 22, 2025
Notice is hereby given that an application for a proposed project or activity has been submitted to
the Colorado Air Pollution Control Division for the following source of air pollution:
Applicant: PDC Energy, Inc
Facility: Market Federal 18 Sec HZ
Well Production Facility
NWNE quadrant of Section 18, Township 7N, Range 65W
Weld County
The proposed project or activity is as follows:
Process Description:
A commingled liquid stream (containing natural gas, condensate and produced water) flows from
eight (8) wells, through one (1) of eight (8) heated separators, each with a 0.500 MMBtu/hr burner.
In the separators the fluids are separated into individual phases (natural gas, produced water,
hydrocarbon liquid). The fluid phase then exits the separators as follows: The hydrocarbon liquid
(condensate) flows from the separators to one surge vessel which further separate the fluid phase.
The hydrocarbon liquid then flows to a third party pipeline to be sold via a Lease Automatic
Custody Transfer (LACT) unit. At times when a surge vessel is not operational, the condensate flows
to four (4) 538 bbl condensate storage tanks. The tank vapors are sent to the enclosed combustors.
Once adequate volumes are accumulated, the condensate is loaded into a tank truck and sold. Any
produced water that may be generated is sent to six (6) 400 bbl produced water storage tanks. The
tank vapors are sent to the enclosed combustors. When an adequate volume of water is
accumulated, it is trucked off-site to an appropriate treatment facility. The natural gas phase exits
the separators and can flow to engine-driven compressors, which compress the gas before it is sold
into a pipeline, or flow directly to a pipeline. Natural gas exiting the separators can also be
compressed and sent back to the wells to stimulate production in gas lift service. Tank truck

loading emissions also occur during the condensate loading of the tank trucks for sales. The
condensate is submerge-filled as it is loaded into the truck. As the condensate is pumped into the
truck, the fluid displaces the vapors. The displaced truck vapors are sent to the condensate tanks
via a vapor balance, and then to an enclosed combustor.
Public Notice Requirements: The owner or operator is requesting syn minor limits on the PTE of
VOC to avoid major source requirements. As a result, project is subject to a 30 days public notice
The division has determined that this permitting action is subject to public comment requirements
under Colorado Air Quality Control Commission Regulation Number 3, Part B, Section III.0 due to
the following reason(s):
• This source is requesting a federally-enforceable limit on the potential to emit to avoid
other requirements. (Regulation Number 3, Part B, Section III.C.1.d.)
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 number
25WE0104 are available on the division website: Air Permit Public Notices
