Air Pollution Control Division
Website Title: Crestone Peak Resources Operating LLC - Hingley 18H N167 Battery - Weld County
Notice Period Begins: April 6, 2023
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: Crestone Peak Resources Operating LLC
Facility: Hingley 18H N167 Battery
Well Production Facility
NENE Quadrant, Section 18,Township 1N, Range 67W
Weld County
The proposed project or activity is as follows: Point 001 has updated site specific emissions factors as a
result of sampling and reduced requested throughput from 532,900.0 barrels of condensate per year in
issuance 1 to 98,500 barrels for this issuance. While the emisisons factor for VOC increased from last
issuance, the requested uncontrolled and controlled emissions decreased From 684 and 34.2 tpy
respectively in issuance one to 140 and 7 tpy for this issuance. Requested emissions for all other criteria
pollutants and HAPS also decreased for this point. Therefore the modification to point 001 represents only a
decrease in emissions.
Point 002 has dropped below APEN reporting thresholds and is cancelled in this project, representing
decrease in emissions.
Point 003 continues to use state default emission factors for loadout and reduced it's throughput from
532,900 to 98,500. All requested emissions from point 003 have decreased correspondingly.
Point 013 has updated site specific emissions factors as a result of sampling and reduced its requested
throughput from 4.5 MMscf per year to 3.80 MMSCF. Although SSEF for VOC increased for this issuance, the
reduction in throughput results in lower requested VOC emissions than in issuance one. Therefore
modification of point 013 represents a decrease in emisisons.
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 20WE0896 are available
on the Division's website at https://www.colorado.gov/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
