INF C PHE Comment
Website Title: REP Processing, LLC - Severance Compressor Station - Weld County
Notice Period Begins: February 3, 2026
Notice Period Ends: March 5, 2026
NOTICE is hereby given that an Operating Permit application has been submitted to the Colorado
Air Pollution Control Division, 4300 Cherry Creek Drive South, Denver, Colorado 80246-1530, for the
following source of air pollution:
Applicant: REP Processing, LLC
6301 N. Western Ave Suite 200
Oklahoma City, OK 73118
Facility: Severance Compressor Station
REP Processing, LLC has applied for an Operating Permit for the Severance Compressor Station in
Weld County, CO. The REP Processing, LLC Severance Compressor Station receives natural gas from
nearby well sites via a gathering system pipeline. Gas entering the station flows into an inlet slug
catcher to prevent liquids from entering the compressors. Gas from the slug catcher is then
directed to the compressors. Eight (8) Waukesha L7044 GSI S5 compressors compress the gas.
Following compression, the gas is sent to a dehydration unit (SK-4100). The dried gas is then sent
to the gas pipeline. TEG regeneration vapors from the dehydration unit still vent are directed to a
`BTEX' condenser, and then to an enclosed combustor. Flash gas from the dehydration unit's flash
tank and condensate from the TEG regeneration skid are directed back to the facility inlet slug
catcher. Liquids from the inlet slug catcher are directed to a 3-phase separator vessel (V-7100).
Vapors from the separator are routed to a combustor (FL-9500). Condensate from the 3-phase
separator is sent to the condensate surge vessel (V-8100), with the vapors routed to the combustor
(FL-9500). The condensate leaves the facility vis pipeline. Produced water from both the 3-phase
separator vessel and the condensate surge tank vessel will be sent to a 400-bbl produced water

storage tank (TK-9000). Vapors from the produced water tank and loading operations are directed
to the vapor combustion unit (FL-9500). Produced water is removed from the tank via truck.
Additional emissions at the facility include compressor blowdowns (BD-1) and pig launching (PG-1).
A copy of the application, including supplemental information, the Division's analysis, and a draft
of Operating Permit 230PWE518 are available on the Division's website. The Division has made a
preliminary determination of approval of the application. Based on the information submitted by
the applicant, the Division has prepared the draft operating permit for approval. Any interested
person may contact the division at cdphe_apcd_title_v@state.co.us to obtain additional
information. Any interested person may submit written comments to the Division concerning 1) the
sufficiency of the preliminary analysis, 2) whether the permit application should be approved or
denied, 3) the ability of the proposed activity to comply with applicable requirements, 4) the air
quality impacts of, alternatives to, and control technology required on the source or modification,
and 5) any other appropriate air quality considerations. Any interested person may submit a
written request to the Division for a public comment hearing before the Colorado Air Quality
Control Commission (Commission) to receive comments regarding the concerns listed above as well
as the sufficiency of the preliminary analysis and whether the Division should approve or deny the
permit application. If requested, the hearing will be held before the Commission within 60 days of
its receipt of the request for a hearing unless a longer time period is agreed upon by the Division
