what happened
It is too soon to pinpoint the exact cause of the incident. We are conducting an investigation and will provide updates on our findings. Based on the limited information available now, it appears that during routine operations, a failure of surface equipment resulted in the release of water, oil, and gas.

The incident happened during the completions process when transitioning from installing a tubing hanger to installing an adapter flange lower master valve.

current activities
- Air quality monitoring have been ongoing, and the results have been below levels of concern, and no public health effects are expected. There are currently 7 air monitors on-location and 5 off-location remote monitoring stations.

- Pairs of Rapid Assessment Teams and Sampling Groups have been deployed to conduct visual impact assessments on all water bodies, ditches, land, and private residences within a 1-mile radius from the incident. Groundwater well sampling has also begun.
- Impacted wildlife areas are being assessed with the help of a Chevron wildlife specialist and supporting regulatory agencies.
- The Greeley Canal clean-up is nearly complete. On-site soil testing for the presence of contamination have confirmed the successful removal of impacted soils along the channel bottom and sidewalls. We continue testing along the restored sections.
- Reclamation efforts along Willow Creek continue. We continue to work under the direction of state and federal regulatory agencies.
working together
Immediate action was taken to assess the safety of employees, contractors, and the public. More than 340 people mobilized to support the response effort. Unfortunately, one contractor employee was injured and treated at a local medical facility. All other personnel are accounted for.
As we are now in the recovery phase, a Unified Command has stepped down and transitioned into a Chevron response with oversight from the Energy and Carbon Management Commission’s (ECMC) authority. The Unified Command was comprised of Weld County Office of Emergency Management, Chevron, Galeton Fire Protection District, and the Environmental Protection Agency.
Our priority remains the safety and security of our neighbors, our workers, and the environment. Air quality monitoring has been ongoing, and the results have been below levels of concern.
As a precaution, some residents within a half-mile of the well pad were temporarily relocated. We are working with those residents and Weld County to conduct air monitoring, any necessary cleaning, and return residents to their homes.
community response
Chevron maintains ongoing communication with impacted homeowners and remains committed to supporting their safety and return home. Roughly 75-100 people contracted by Chevron showed up to help move the items from the Galeton Elementary School to a temporary location at Benjamin Eaton Elementary School. They assisted in packing, loading, and unloading hundreds of boxes to the appropriate temporary rooms. We are also currently evaluating mental health services to offer to the impacted parties.

environment
- The focus has been on safe management of the well site. We have begun to conduct sampling of soil or groundwater. With the well secured, we will begin evaluating follow-up actions in cooperation with government agencies.
- Neither Chevron nor responding agencies are not aware that any sources of drinking water have been affected. Some liquid from the well entered Willow Creek at the beginning of this incident. The liquid from the site was diverted into a collection area to protect the creek. Booms have been placed in the creek to help prevent oil in the water from traveling further downstream and are continuing to remove oil and water from the creek for safe disposal offsite.
- It is unlikely that well water would be affected by this incident. If you have concerns about your well, Weld County Department of Public Health and Environment has a free volatile organic compound testing program. You can learn more about this service on the Weld County website. However, the presence of any contaminants in your well water does not necessarily mean that your well was affected by this incident. A proper evaluation of the source of any contaminants would still have to be done.
