Website Title: Noble Energy, Inc. - SLW RNCH B01 ECONODE T5N-R64W-S12 L01 - Weld County
Notice Period Begins: April 26, 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: Noble Energy, Inc.
Facility: SLW RNCH B01 ECONODE T5N-R64W-S12 L01
Well Production Facility
SENE quadrant of Section 1, Township 5N, Range 64W
Weld County
The proposed project or activity is as follows: Noble Energy Inc submitted on 2-9-2023 a permit application
to modify permit 13WE2740. The permit modification included: (1) reduction of requested throughput and
emissions from point 004 (Condensate Tanks) and update of site -specific emission factors; (2) reduction of
requested throughput and emissions from point 005 (HC loadout) and adoption of state emissions factors; (3)
reduction of requested throughput and emissions from point 006 (PW Tanks) and adoption of state emission
factors; (4) reduction of requested throughput and emissions from Point 014 (VRT flaring). With the
modification, this well production facility is considered a synthetic minor source of VOC under the TV and
NNSR programs.
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 13WE2740 are available
