Notice of a Proposed Construction Permit Warranting Public Comment
Website Title: Summit DJ -O Operating, LLC - Makena Gas Plant - Weld County
Notice Period Begins: March 12, 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: Summit DJ -O Operating, LLC
Facility: Makena Gas Plant
Natural Gas Processing Plant
NESE quadrant of Section 25, Township 8N, Range 62W
Weld County
The proposed project or activity is as follows:
Summit DJ -O Operating, LLC submitted an application on 8/20/2024 requesting the
replacement of an existing engine under Point 008 and currently covered under General Permit 02.
The Makena Gas Plant is a 60 MMscfd cryogenic gas plant, designed to remove CO2, water, and
natural gas liquids from field gas. This specific engine drives a compressor responsible for
compressing residue gas from a demethanizer into a product gas pipeline.
This facility is considered an existing major stationary source of NOx and VOC. The new engine is
considered a new emissions unit and major modification applicability follows BAE-PAE where BAE _
zero and PAE = PTE. PTE of NOx is 6.5 tpy (tons per year) and PTE of VOC is 11.4 tpy which are
below the significant threshold of 25 tpy. As a result, the addition of the new unit is not considered
a major modification. It should be also noted the new engine is replacing another existing engine
with the same rating and debottlenecking of other units is not expected from this project.
Furthermore, the operator is requesting federally enforceable limitations on the PTE of NOx in
order to avoid major stationary source requirements and major modification requirements. As a
result, project is subject to a public notice period of 30 days.
