Arapahoe County reviews permits for Wetterhorn and Harbordale oil drilling sites

The Colorado Energy and Carbon Management Commission (ECMC) held a significant hearing on July 2, 2025, focusing on the proposed development of two oil and gas sites in Arapahoe County. This meeting is crucial for local residents as it addresses both environmental concerns and energy needs in the community.

The proposed sites, known as the Harbordale and Wetterhorn Andes, are set to cover approximately 5,440 acres and involve the drilling of up to 38 new horizontal wells. The developers emphasized their commitment to minimizing environmental impacts, stating that the sites are strategically located over 2,000 feet from the nearest residential building units (RBUs) and over a mile from schools and childcare centers. This distance is designed to protect public health and safety, a primary concern for community members.

Key discussions during the meeting included the rigorous permitting process that has been undertaken, which involved multiple neighborhood meetings and consultations with Arapahoe County officials. The developers reported that no major issues have been identified during the review process, and they are on track to finalize their permits by July 2025.

Air quality monitoring was a significant topic of interest. The commission confirmed that Arapahoe County regulations require air quality monitoring for the first three years of production at all sites. This includes the installation of two monitoring wells on each pad site to ensure compliance with environmental standards. The developers have submitted an air quality monitoring plan that is currently under review, which will detail the locations of these monitors.

In addition to air quality measures, the developers outlined various best management practices aimed at reducing emissions and protecting local wildlife. These include using utility power for drilling operations, implementing sound walls during drilling, and conducting avian surveys to avoid disturbing local bird populations.

The commission's approval of this project could have significant implications for the local economy, potentially creating jobs and increasing energy production in the region. However, it also raises concerns about environmental impacts, which residents are keen to monitor closely.

As the ECMC continues to evaluate the proposal, community members are encouraged to stay informed and engaged in the process, ensuring that their voices are heard in discussions about the future of energy development in Arapahoe County.
