Bronco Comprehensive Area Plan (CAP)

As of August 10, 2022, Oxy achieved approval for the Bronco CAP from the ECMC. Oxy has a 30-year legacy in Colorado and is committed to serving as an innovative and sustainable leader in the oil and gas industry.


What is a CAP?

A CAP is a proposed plan covering future oil and gas operations in a defined geographic area. The purpose of a CAP is to propose development based on thoughtful and comprehensive planning and cumulative impact considerations. A CAP focuses on infrastructure location, Best Management Practices (BMPs), and centralization of facilities, among other development aspects.

Bronco CAP Specifics

  • Since the initial proposal in 2022, KMOG has removed 2 proposed pads from the Bronco CAP, updating the total pad count to 9. Additionally, KMOG is now drilling 141 wells instead of the proposed 209 wells.

  • ​The planned development avoids impacts on residents by well pads, and facilities are now located greater than three (3) miles from the nearest Residential Building Unit.

  • While the Bronco CAP does fall within a Disproportionately Impacted Community, there are no Residential Building Units near the pad to trigger additional measures.

  • Traffic will be contained within the Bronco CAP boundary and U.S. Highway 34, avoiding County roads or residential streets.​

Bronco Structure

The Bronco CAP is made up of two OGDPs (Colt and Filly). Colt and Filly, respectively, have locations, hearings, and schedules unto themselves. For information regarding the events of Colt and/or Filly, please see "Progress and Project Updates" below.

  • KMOG is proposing a water recycling operation on location capable of treating approximately 10,000 bbls of water per day.

  • Produced water will be piped from locations in the CAP lands to the recycling equipment and piped to other locations for completions operations.

  • Using recycled water will reduce the need for freshwater and decrease the amount of water sent to disposal.

  • Starting with the first location being turned over to production, water will flow to the recycling system and then be used for subsequent completions until the last well has been completed in the Bronco CAP lands.

  • Once the last well has been stimulated, all produced water will be piped to disposal, eliminating truck traffic associated with produced water hauling.

The aforementioned techniques allow KMOG to eliminate truck trips that otherwise would be necessary. We can estimate that the following methods will contribute to the elimination of the following truck trips:

Water on Demand:

Colt - 591,380

Filly - 564,112

Oil Piping:

Colt - 214,561

Filly - 276,129

Produced Water Piping:

Colt - 30,170

Filly - 31,677

Our Best Practices

We strive to make our activities compatible with the surrounding community and use various techniques to avoid, minimize, and mitigate the temporary impacts associated with development. Our team designs each location after careful consideration of the area’s specific attributes. We deploy the following strategies to mitigate possible impacts including:  


Noise: We will perform a mitigation and monitoring noise model for the Bronco CAP and will determine compliance prior to the start of construction. 

Road and Traffic: We reduce traffic as much as possible through oil transfer and Water-On-Demand systems. The oil produced from our horizontal locations is transported off-site through a pipeline, eliminating the need for trucks. We transport the water used in hydraulic fracturing through our innovative Water-On-Demand pipeline system, further reducing truck traffic.

Since its inception in 2012, this technology has enabled Oxy to eliminate 60 million miles of truck traffic from the roads in Weld County, reducing emissions, dust, road wear, and inconvenience to our neighbors. This system also reduces our surface footprint by eliminating the need to store water in tanks onsite during well completion.


Monitoring Emissions: During drilling and completions, independent third-party environmental air quality experts perform continuous air quality monitoring. During the development phase, we will post monthly monitoring reports created by the third-party consultant to this webpage.
Independent third-party air quality experts use traditional and innovative technologies to add context to and validate the data collected. Air monitoring stations include a weather station, a hydrocarbon analyzer, and carbon sorbent tubes. In addition, strategically placed air canisters may supplement data from the air monitoring stations. Air samples are collected and analyzed according to EPA standards. The results are compared to health guideline values set by the CDPHE.
Air monitoring data is collected continuously and is monitored 24/7 by our Integrated Operations Center (IOC). Our monitoring program establishes response and investigation levels designed to protect the health, safety, and welfare of communities, our employees, and the environment. Additionally, our 24/7 IOC ensures that responses are timely and effective.  
To monitor emissions near our production facilities, we have an in-house emissions team that conducts leak detection and repair inspections. During the production phase, every facility is inspected periodically by trained individuals using a handheld infrared camera. We also use infrared camera-equipped drones and conduct frequent audio/visual/olfactory inspections to detect and control emissions.


Remote Monitoring: Our Integrated Operations Center (IOC) in Platteville, staffed 24 hours per day, 365 days per year, enables real-time monitoring of the wells, production facilities, and water tanks. Additionally, the system allows us to monitor personnel locations and surrounding features, including sensitive areas, bodies of water, habitats, and communities. The IOC also serves as a point of contact 24/7 for inquiries from community members.

Progress and Project Updates

This page will be updated regularly with information and permitting updates.

Current Phase – Colt OGDP hearing is currently scheduled for March 6th. Filly is currently in review and was submitted on February 7, 2024.


Completed Phases

  1. The ECMC deemed the Bronco CAP as complete, meaning all the information submitted was ready for the consultation phase and public comment.

  2. The ECMC posted the CAP application and supporting exhibits on its website. Please see the link to the right.

  3. We provided notice of hearing via certified mail to all interested parties, including surface owners, mineral owners, Weld County, and State agencies, including CPW, CDPHE, and the State Land Board. 

  4. Oxy held a community meeting on May 23, 2022, with the purpose of providing the project overview and answering questions. Meeting slides are linked to the right.

  5. The ECMC approved the Bronco CAP on August 10, 2022.

  6. We provided a 30-day application notice for our Weld County Comprehensive Development Plan (Plan via certified mail to interested parties).

  7. Weld County approved the CDP on April 27, 2023.

  8. The first five 1041 WOGLAs were submitted to Weld County Oil and Gas Department on various dates, including: (East Street 11.30.23, Hi Chapparal 08.08.23, Hickory Miguel 12.26.23, Daniel Boone 01.24.24, Roan Angel 11.17.23.)
