Notice Of A Proposed Renewal Title V Operating Permit
- Warranting Public Comment
Air Pollution Control Division
Website Title: DCP Operating Company, LP - Platteville Natural Gas Processing Plant - Weld County
Notice Period Begins: April 3, 2023
NOTICE is hereby given that an application to renew an Operating Permit 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: DCP Operating Company, LP
6900 E. Layton Ave.
Suite 900
Denver, CO 80237
Facility: Platteville Natural Gas Processing Plant
13675 Weld County Road 34
Platteville, CO 80651
DCP Operating Company, LP has applied to renew the Operating Permit for the Platteville Natural Gas
Processing Plant in Weld County, CO. This facility is a natural gas processing plant. The operating permit
renewal for this facility includes the following changes: modify permit limitations, emission factors and
calculation methods to reflect the facility's current mode of operation, as requested in the renewal
application, one minor modification application and two significant modification applications (with
addendum), incorporate the applicable requirements of Colorado Construction Permit 01WE0430, update
monitoring requirements to be consistent with recently issued permits and include the most recent version
of applicable federal and state regulations. This operating permit renewal incorporates equipment
previously permitted under Colorado Construction Permit 01WE0430, which includes the EG dehydration unit
and facility flare. Emission limitations for the facility flare were not modified with the operating permit
renewal. The renewal operating permit adds the contribution of assist gas into the EG dehydration unit
emission limits, updates the fugitive VOC emission limit based on a more recent component count, and
updates all engine emission limitations to align with Colorado Regulation No. 7, Part E, Section I.D.5.
requirements, as requested in the minor and significant modification applications received during the permit
term. These modifications result in an overall decrease in facility -wide emissions (-150.4 tpy NOx, -0.8 tpy
CO and -59.8 tpy VOC). A facility -wide HAP limit was introduced to ensure major source requirements are
not triggered under federal rules. A copy of the application, including supplemental information, the
Division's analysis, and a draft of the Renewal Operating Permit 02OPWE252 are available on the Division's
website at https://www.colorado.gov/cdphe/air-permit-public-notices. 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 renewal 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
